Air Conditioning Dilemmas: Is Your Cool Air Going Out the Window?

This entry was posted in Air Conditioning on by .

As spring training gets underway and homeowners prepare for another blistering summer in Phoenix, DST seems like a good idea. No, not daylight savings time. DST – Demand a Spring Tune-up for your air conditioner and have our expert professionals perform a home energy assessment to see where you might be losing precious cool air. Your air conditioning system uses a tremendous amount of electricity to cool down the hot desert air. In summer, up to 60 percent of your monthly energy bill can be attributed to your air conditioner. It’s an unfortunate fact that many Arizona AC systems are working overtime cooling the great outdoors due to cold air escaping through substandard window and door seals, leaky ducts and lack of proper home insulation. Here are a few things you can do to make sure your air conditioner is working efficiently to cool your home:

  • Lack of Proper Ceiling Insulation Can Cause Your Electric Bill to Go Through the Roof
    In Arizona, many home air conditioning units are located on the roof. During the summer, in the heat of the day, roof temperatures can exceed 140 degrees. Without proper insulation, your attic can be a major factor in contributing to inefficient cooling and cold air loss. When your attic is super-heated it affects the temperature throughout your entire house. Air conditioning ducts in the ceiling are warmed by the surrounding hot air and reduce the overall efficiency of your AC system, which means your air conditioner uses more electricity and your bill goes through the roof.

  • Leaking Ducts
    Generally speaking, air conditioning ducts are out of sight, out of mind. However, they are crucial to the delivery of cold air throughout your home. If you’ve got leaks in your duct system, that means cold air is escaping into thin air. One of the most common areas for leaking ducts is in the attic. Over the years, we have seen many duct disasters including ductwork that was improperly installed when the house was built or (even worse) ducts that have been damaged by repairmen working on other issues in your home such as wiring or other home repairs. If your ducts have been neglected for years, this spring might be the right time for duct inspection.

  • Don’t Forget Where the Heat Pours In
    Once you’ve checked your windows and doors for proper seals and insulation, don’t forget – cold air not only goes out, heat pours in from large, south facing picture windows and patio doors. Proper window treatments and sun block curtains or heavy blinds help insulate Arizona homes and keep the sun from heating up your home.

Cool Questions Curious Customers Ask Air Conditioning Experts

This entry was posted in Air Conditioning on by .

Over the years, we’ve worked with thousands of homeowners in the ever-expanding Phoenix metro area. Installing new HVAC systems, performing regular service and providing emergency repairs in the hottest city in America keeps us very busy indeed. We’re grateful for all our customers. In our line of work, given the complex nature of the electrical circuits, motors and multiple components involved, we can honestly say, no two air-conditioning/duct systems are exactly alike. Customers call us all the time with questions about their air conditioners. Here are few questions we’re asked on a regular basis:

  • My air conditioner isn’t working. How can I tell if it’s broken?
    We often receive emergency calls in the middle of the night from frantic customers claiming, “My air conditioner just stopped – you’ve got to get someone over here right away.” As soon as you notice your AC is not working, there are a few initial troubleshooting steps to take. First, checkout your thermostat. If the screen is blank or dark, that could be the problem. If the batteries are dead or there’s an electrical wiring problem preventing electricity from getting to the thermostat, then it’s not communicating with your HVAC system. If the thermostat appears to be in working order, then the next step is to check the circuit breakers for you AC system. If a breaker has been tripped, you’ll need to reset it. Turn it all the way off then back on again. Remember, some circuit breakers can be tricky. They’re not always clearly marked (although they should be), and they may require turning off and on more than once. If you reset the system, and your air conditioner turns on and works for awhile, then trips the breaker again, there is definitely something wrong and you should give us a call.

  • My electric bill has increased dramatically. Is there something wrong with my AC?
    The Department of Energy states that air conditioning is responsible for the lion’s share of your monthly electric bill – especially in the summertime in Phoenix, when your air conditioner could be accountable for as much as 60 percent of your entire energy consumption. Common factors increasing your energy use include the settings on your thermostat. If you’re keeping it nice and cool inside your home, and your air conditioner is operating constantly, you’re going to run up a significant utility bill. That might seem so obvious, you wonder why we mention it. A few degrees higher or lower on your setting can make a big difference. Forgetting to adjust the thermostat while you’re at work can be significant. You might want to consider installing a new smart, wi-fi enabled thermostat which will give you more control over your air conditioning system. Other factors include refrigerant leaks, dirty coils, faulty fans or capacitors or other problems that impede air flow and lower the efficiency of your air conditioner. In other words, the harder your air conditioner is working to achieve the cool temperature you desire in your house, the more energy you’re going to use. Ideally, you should schedule service twice a year for your HVAC system to make sure everything is working properly.

  • How will I know when it’s time to replace my air conditioning system?
    This is an important issue for all Arizona homeowners because replacing your air conditioner is something you’ll need to do sooner or later, as well as a major expense, quite a considerable job and not something you want to do in the middle of a blistering summer. In other words, if you’re trying to squeeze another year or two out of your old system, you may live to regret that decision. If your air conditioner happens to break down during a major heatwave when AC repair companies are overloaded with service calls, you could be without air conditioning for days. The best approach is to establish the age of your air conditioner (most systems will last up to 8-10 years). Have regular maintenance performed by the same company so they will get to know your AC system and understand its strengths and weaknesses. And keep track of your repairs so when the expenses total more than a third of the cost of a new system, you’ll know it’s probably time to consider a newer, more efficient AC system.

We’ve Got the Answers to Your Questions

If you’ve got questions, we’ve got answers. Our friendly service technicians will take the time to perform a thorough and complete service inspection of your entire system and provide you with a detailed evaluation so you can determine what’s best for the comfort of your family this coming summer.

Remodeling or Building a New Home in 2019? Don’t Overlook the Importance of Air Conditioning

This entry was posted in Air Conditioning on by .

Flip or Flop, Property Brothers and Fixer Upper. These home remodeling shows present viewers with a behind the scenes look at the design, construction and home renovation process. Most home makeover shows feature variations on a similar theme. Tired, distressed house meets optimistic, energetic designer/builder who, through cheerful hard work and plucky determination, solves problem after problem, presenting a fabulous “new” home – all on time and under budget. Just for good measure, this is accomplished in 44 minutes (don’t forget, 16 minutes for commercials). However, a full disclosure statement during credits at the end of the show might read, “Results may vary. Your home building or remodeling project may take more time.”

Style and Design Verses Functionality and Livability

HGTV’s home remodeling shows are successful because they reveal how designers achieve a certain look. It’s no secret, architects, designers and builders understand that visually stunning style and design are the keys to selling projects. However, homeowners know it’s the inner workings of a house that make it comfortable to live in. That’s why, especially in Arizona, it’s crucial to put emphasis on the engineering and design of the air conditioning system before you finalize plans for your new or remodeled home. If you are in the process of constructing a new home or doing an extensive addition or renovation project, don’t wait until it’s too late to bring us in for an HVAC consultation.

Air Conditioning Factors to Consider in Your Newly Constructed or Remodeled Home

During the hot summers in Phoenix, achieving constant, cool comfort in every room in your home, when it’s 100 plus degrees outside, can be quite a challenge. Here are a few factors to consider when designing – or revamping your AC system:

  • The Right HVAC System for Your Home – Whether you are building a new home or renovating, getting the right size, model and style of air conditioner/heat pump is crucial. Many homeowners equate size with cooling power. A common theory is, a bigger AC unit should do a better job of cooling the house. However, this is not always the case. Our professionals will perform a full assessment of your project to determine tonnage and just the right amount of cooling power needed. Our experts will explain it all, so you can make the right decision for your home.
  • HVAC System Location – In Arizona, many homes have air conditioning systems located on the roof while others are placed alongside the house or in the back. Deciding where to locate your HVAC system is an important air conditioning design/engineering judgment call. Rooftop or ground level AC systems have different advantages and disadvantages. Our knowledgeable service technicians will present you with the pros and cons of each option so you can make an informed decision.
  • Ductwork – Unsung and Unseen – Because ducts are hidden behind walls, in the ceiling between rafters or under the floors, homeowners rarely think of them. However, in new construction or extensive home remodeling, ductwork is critical and often does not receive the attention it deserves. For instance, just adding a duct to an existing system to support a room addition is not sufficient and can throw off the balance of your entire home. Ducts can be damaged or blocked during the construction process – we’ve seen it many times. Ductwork needs to be completed with care and checked multiple times before the walls are closed-up.

When It Comes to Air Conditioning and Construction, Let Us Be Your “Cool” Watchdogs

The list of installation factors to consider during construction is lengthy. It’s important to note that issues not dealt with during the construction process can have long-term ramifications for your home. Our friendly professionals will be happy to meet with you to assess your needs and provide you with information and options. Why not give us a call today?

Wishing You a Happy New Year from the Entire Team at Cool Blew – Your HVAC Experts

This entry was posted in Air Conditioning on by .


Happy Holidays! Cool Blew has been delivering the “cool” to families all over the Valley since 2002. As we get ready to bid farewell to 2018, our family wishes you and your family the very best in the new year ahead. We thank all our customers for another great year. We couldn’t be the experts in HVAC repair and installation if it wasn’t for you!

Good Health, Resolutions and the Air We Breathe

It’s no surprise that New Year’s resolutions are often health related. In a recent YouGov poll, the top two resolutions for the coming year in the U.S. are to eat healthier and get more exercise. One of the most critical elements of good health, but often taken for granted, is the air we breathe. If you or a loved one suffers from asthma or respiratory conditions, you know that poor indoor air quality can negatively impact your family. In the dusty, desert climate of Arizona, cool air-conditioned, filtered air inside your home makes a huge difference for healthier, happier lives.

Consider Making a Resolution to Upgrade Your AC in 2019

Every year, homeowners are faced with deciding which major improvements will fit in their budget within a given 12-month period. Because AC units are built to last a long time and are often out of sight, out of mind, air conditioning can be one of those home improvement projects that gets pushed back from one year to the next. Often, other more visible home repairs take precedence. If your air conditioner is over ten years old or if you’ve noticed service calls and repairs adding up, it might be time to consider a major upgrade or purchasing a new HVAC system. Our service technicians will perform a full HVAC evaluation and inspect each and every component in your system to help you decide what is needed for great AC in the coming year.

When It Comes to AC Service, We Say Be Proactive, Not Reactive

Many Phoenix homeowners are surprised to learn that winter is an excellent time for major HVAC service. Scheduling maintenance in January, February or March guarantees your air conditioner will be in top form once the hot weather arrives. Unfortunately, many people wait for their AC unit to breakdown before they call for repairs. We refer to that as reactive service. Better to be proactive and get out in front of AC issues. Our service pros are great at detecting and fixing small problems before they grow into major ones.

Our Number One Resolution for 2019 – Deliver Great Service and Value to Our Customers

At Cool Blew, we understand the importance of delivering first rate service and great value to all our customers. As a family run business, we get it. In summertime, your air conditioner is the most important appliance you own. Making sure your AC is running smoothly and trouble free all year long is our number one priority. We consider our service professionals to be the best in the Valley and we love providing the “cool blew” wherever we go.

Happy New Year from the Gang at Cool Blew

We thank you for another wonderful year and we’re grateful for every call we received in 2018. We know we have to earn our reputation every day. We appreciate the opportunity to provide great HVAC service to families across the Phoenix metro area. We wish you all the best in 2019! Happy New Year!

Does Closing Room Vents Lower Cooling Costs?

This entry was posted in Air Conditioning on by .

We get it! You’ve been paying high cooling costs for months to keep your home comfortable during the long, sweltering Arizona summer. And, temperatures are still climbing above 100 degrees even though fall is just around the corner. You want relief and may be tempted to shut room vents to save a few dollars.
Don’t do it!

But, It Seems Logical…

It may make sense that if you shut room vents, you’ll be using less air to cool down your home. Unfortunately, air conditioning doesn’t quite work that way. Room vents are not installed in your home to restrict airflow. Rather, their purpose is to control the direction of air movement as it passes into a room.

Shutting a vent all the way doesn’t provide an effective seal, and it can cause damage to your HVAC system. Why? The motor that powers the blower fan in your system’s air handler is designed to push against a maximum air pressure. If the pressure is increased due to a blocked vent, it impacts the motor and will result in a drop in airflow throughout the system. If your system’s blower has a variable speed motor, this pressure will cause the motor to ramp up to its highest power level which will result in higher utility bills and greater stress on the motor. Over time, this can lead to problems with the compressor and evaporator coils.

Alternatives to Shutting Vents

Now that you know that shutting vents isn’t an effective way to save money and may actually cause problems with your HVAC system, it’s good to know that there are some ways you can lower your home cooling costs. Here are some easy strategies that you can use:

  • Maintain a thermostat reading around 78 degrees during the day.
  • Change air filters once a month.
  • Clean vent covers and ensure they’re not blocked.
  • Keep your outdoor unit clean so that it can expel heat.

Capacitor – New Marvel Superhero or Essential Air Conditioning Electrical Part?

This entry was posted in Air Conditioning on by .


Ninety-three million miles away, at the center of the solar system, this perfect sphere of blazing hot plasma (5800 degrees Kelvin) beams relentless heatwave after heatwave to the innocent and perspiring residents of Phoenix. As the Arizona desert becomes super-heated with no end to summer in sight, a sizzling city pins its hopes on the diminutive electrical legend, CAPACI-TOR! Able to start air conditioning motors in a flash, CAPACI-TOR’s electrostatic field is essential in cooling homes and buildings in the Valley of the Sun.

No, “capacitor” is not a new Marvel character for summer release but rather your air conditioner’s electrical superhero. Electric motors within your air conditioner rely on capacitors to run smoothly. Did you know that over three quarters of all AC service problems and repairs are related to electrical issues?

Why Are Capacitors So Important to My Air Conditioner?

HVAC systems contain many electrical circuits, parts and components. If circuit boards can be considered the brains of the unit, then capacitors are the instigators. Capacitors regulate the “start-up” and “run” energy for the electric motors. Capacitors come in all shapes and sizes and are found in virtually all electric motors. In air conditioners, capacitors are small cylinders about the size of a Dixie cup used mainly to store and release electric charges not unlike a short-term battery. Capacitors regulate the motors in the compressor, blower and fan. If the capacitor fails, then the motor will soon stop working, and you may notice a clicking sound or a loud hum. Either noise is, unfortunately, not a good sign and you should call for service immediately.

What Can Cause A Capacitor to Fail?

The electrical system in your air conditioner is built to last. However, Arizona is a tough environment for your most important summertime appliance. Electrical thunderstorms, lightening, power failures and resulting power surges (when the power grid goes back on) can wreak havoc on capacitors. Like all the components in your air conditioner, capacitors can wear down over time. AC units operate six months or more in Phoenix year in, year out. All that heavy use and vibration takes a toll, especially on precision electronic parts.

What Should I Do If My Air Conditioner Becomes “In-Capacitated?”

Electrical problems and capacitor repairs are not for do-it-yourselfers. As capacitors fail, they often open up which, if not handled properly, can result in leakage of toxic materials. Our trained technicians will perform a detailed inspection and restore your capacitors and air conditioner to top form. Just like your car, regular maintenance on your HVAC unit will help prevent major problems from occurring. Why not call the experts at Cool Blew today!

Is It Time to Consider a New Air Conditioner for Next Summer?

This entry was posted in Air Conditioning on by .


Labor Day marks the unofficial end of summer for most regions in the U.S. However, for Arizona residents, summertime extends well beyond September with triple digit temperatures registering in October and November. The unrelenting desert environment and extreme temperatures push your air conditioning unit to the limit. If you’ve had a difficult summer due to air conditioner issues and downtime, you know how frustrating it can be to live without proper home cooling while your air conditioner is getting repaired. If your unit is nearing the end of its useful service life, now might be the perfect time to consider your options and plan ahead so you have a trouble-free summer in 2019.

I’ve Paid a Lot of Money for Repairs – I Don’t Even Want to Think About My AC

Human nature tends to deal with problems as they present themselves. If an issue has been solved, most people move on. If you’ve paid for air conditioner repair bills, logic would seem to dictate trying to squeeze another year out of your current unit. Depending on the age and service record of your air conditioner, that may or may not be a good idea. In other words, repair bills tend to increase as your air conditioner nears the end of its life. Here are five questions to consider regarding this essential home appliance.

  1. What Are the Benefits of Purchasing A New Air Conditioner?
    Probably the number one benefit to purchasing a new air conditioner versus continued repairs on your old unit is peace of mind. AC units seem to break down at the absolute worst times (during heatwaves, long holiday weekends, just before family events.) If you are living under the constant fear of not knowing what will happen next, it might be time to opt for a new unit. Other advantages include cleaner air and significant energy savings. Choosing a new AC unit with a high SEER rating will give you better energy efficiency which will result in lowering your monthly electric bill.

  2. How Old Is Your Air Conditioner?
    Phoenix has experienced incredible growth over the last decade. Many residents are new to the area. Unless a homeowner purchased their air conditioner, most people are not aware of the exact age of their unit. Air conditioners are manufactured to high standards with many AC units lasting 10 years or more. However, the severe desert climate, with its dust storms, high winds and intense heat, punishes your air conditioner and makes it work much harder. In fact, most AC units run full blast for six months out of the year. That’s a lot of wear and tear. Much like an automobile that has been driven hard for many years in a row, at a certain point, major components start to breakdown. It is not uncommon for Arizona air conditioners to need to be replaced after seven or eight years of service.

  3. When It Comes to Repairs – How Much Is Too Much?
    The nightmare scenario for homeowners is paying thousands of dollars for major repairs two or three years in a row only to find out you need to replace the entire unit anyhow. There is a general rule of thumb that states if your estimated repair bills are going to exceed a third of the cost of a new unit, you might be better off to skip the repairs and opt for a brand-new air conditioner. Remember, if your unit is eight, nine or ten years old, many of the major components will need to be replaced.

  4. I Don’t Know Anything About Air Conditioners – How Can I Make an Informed Decision?
    As with any major purchase, knowledge is your best friend. The perfect place to start is with a complete HVAC inspection and check up by the experienced professionals at Cool Blew. You’ll want to establish the general condition of all phases of your HVAC system. If you have service records, you can discuss them with our experienced service professionals and add up how much has already been spent and what costs you might expect to incur over the next two to three years. Possibly the most important decision you will make is which company you choose to hire. At Cool Blew, we pride ourselves on providing great service and honest advice. We will review your situation with you and recommend the best possible course of action.

  5. Do I Need to Decide Right Now?
    Summers are extremely busy for HVAC companies. Things generally start to slow down in the late fall. For many homeowners, it can take a long time to research, consider all options and complete the decision-making process regarding the purchase of a new air conditioner. Winter in Phoenix (November through March) is the ideal time to have a new unit installed.

    Choose Comfort and Reliability for Your Family

    Whether you’re considering a new air conditioner, need AC repairs or just want to schedule a complete HVAC inspection to give you a clear picture of the status of your HVAC needs, give Cool Blew a call. We’re straight shooters, we’re friendly, and we love providing great AC service

Icy Air Conditioner? What Does That Mean

This entry was posted in Air Conditioning on by .


This time of year, it’s hot by anyone’s standards. This makes it all the more striking when you notice ice on the exterior of your air conditioner. Yes, it happens, and it’s an indicator that there’s a problem that you need to address sooner than later.

Low Refrigerant

The most common cause of ice buildup on your air conditioner is a refrigerant leak within the system. This is often due to wear and tear and ongoing vibration of the unit. High winds, dust and pounding rain associated with monsoon storms can also be contributing factors.

When a refrigerant leak occurs, the temperature will drop on the coils containing the refrigerant. Condensation from the humidity in the air will then form ice on the coils. This kicks off a bad cycle of increasing ice buildup that results in your air conditioner working harder to maintain a cool temperature in your home. Over time, this can lead to the complete failure of your air conditioning system.

Clogged Filters and Coils

Refrigerant isn’t the only problem related to icing of your air conditioning unit. Those monsoon storms can also cause dirt, dust and debris to clog filters and coils, producing inefficient air flow. With reduced air flow, the outcome is the same as with low refrigerant – ice on your air conditioner.

What Should You Do?

While the sight of frost or ice on your air conditioner may initially make you think that the unit is functioning to full capacity, it’s important to know it’s a signal to call for service. Don’t wait for the situation to change. It will, but the next indicator of a problem will likely be an air conditioner that isn’t working at all. If you’ve detected ice on your air conditioner, or if you’ve noticed that the unit is working harder than it used to, don’t delay in calling Cool Blew. Our team of highly trained HVAC technicians has the experience and expertise to diagnose and repair any and every air conditioning problem – including icy coils.

Humanity Verses Humidity – How Moisture Affects You and Your Air Conditioning System

This entry was posted in Air Conditioning on by .


Air conditioning experts often ponder a simple question – what is the perfect temperature?

It’s All Relative

Albert Einstein’s celebrated general theory of relativity transformed the world of physics and astronomy. Not considered light reading, it is complex and difficult to understand. In the hopes of simplifying his concepts, this humorous anecdote has often been told, “When you place your hand on a hot stove for a minute, it feels like an hour; yet when you spend an hour with someone you’re attracted to, it goes by in a minute.” This comparison illustrates the point that the perception of time is relative. So too, is the perception of temperature.

Consider these examples. A round of golf in 80-degree winter weather in the dry Arizona desert (humidity less than 20 percent) feels comfortable. However, in the summer months, 80 degrees in muggy weather with the humidity climbing to 95 percent feels oppressive and stifling. It’s the same temperature, but the difference is the humidity. That’s why people from all over the world flock to Phoenix in winter. The weather is near perfect. Average daytime temperatures hover between 68 and 75 degrees while the relative humidity is an ideal 40 to 50 percent. As we all know, summer in Phoenix is another story.

What Is Humidity?

Humidity is the measure of moisture or water vapor in the air, which can be expressed in absolute humidity or, more commonly, the term most often used on TV weather forecasts, relative humidity. The higher the number, the more water vapor in the air. In Arizona, the months of July, August and September bring monsoons which carry moisture from the Gulf of California north over Mexica to Arizona. Monsoons greatly increase the amount of moisture in the air which you can feel as the storm approaches, and the outdoor temperature drops.

Why Does Humidity Make Humans Feel Hotter?

The human body has a built-in temperature regulator. As our bodies heat up, the hypothalamus triggers our perspiration response, and we start sweating. The water in sweat absorbs heat energy from inside the body and releases that heat as sweat, which evaporates through the pores in your skin (forehead, palms, arms and feet mostly.) If there is extra moisture in the air, your sweat doesn’t have the opportunity to evaporate as quickly, increasing your internal temperature and causing you to feel hot and sticky. Not unlike stepping out of the shower on a hot day in a closed bathroom. Though the water temperature was cool in the shower, upon getting out you notice perspiration on your forehead almost immediately, defeating the purpose of taking a shower in the first place.

Humidity in Your Home

Have you ever noticed water dripping from an air conditioner? Air conditioning systems not only lower the temperature, they also remove moisture from the air circulating inside your home. The evaporator coil of the air conditioner condenses excess water vapor (humidity) into liquid water which collects in the pan and is drained from the system. Think of a glass of iced tea on a hot, humid afternoon. Moisture (water vapor) in the air is condensed by the cold ice in your glass, creating drops of water which run down the side of the glass and pool on the table top.

Is Your Air Conditioning System Running at Maximum Efficiency?

Excess humidity, condensation, drips, drainage issues and standing water can present problems for air conditioning systems. With the monsoon season in full swing, don’t struggle with a malfunctioning air conditioner that isn’t reducing the humidity in your home. Call the pros at Cool Blew today.

Miffed About Myths – 5 Myths About Air Conditioning That Just Aren’t True

This entry was posted in Air Conditioning on by .


Here are five common myths about air conditioning that will make you a crusader for the truth in air conditioning.

As Long as I Change My Filters My System Will Be Fine

Many do-it-yourselfers are satisfied that they’ve done an adequate AC maintenance job by installing new filters once a year. In fact, filters should be changed about once a month and even more often if there are pets in the home. In addition to changing filters, refrigerant levels should be inspected at least once a year. Other parts of an air conditioner need to be cleaned and checked regularly, such as the blower. Certain moving parts also may require routine lubrication. Unless you are a trained technician with the proper tools, you are not going to have the expertise to maintain your HVAC system.

All New Central Air Conditioning Units Are Created Equal

One is as good as another. They’re all basically built on the same principles. It’s true that there are many similarities across manufacturers and brands. However, different companies have strengths in different areas. The main component that is unique in every case is the customer. What are your needs? If you are searching for a new air conditioning unit, it’s in your best interest to speak with a professional who brings years of experience to the table. Choosing the right unit for your home is critical, and proper installation is crucial.

Bigger is Better

It’s as American as hot dogs on the Fourth of July. Everyone knows bigger is better. A large engine makes your car go faster. A bigger fan moves more air than a tiny one, so why not super-size your air conditioning system? Funny thing about air conditioners and cooling power – size matters – the correct size. Consult with our AC experts to see if you have the proper sized unit for your home. Have you added a room or remodeled extensively? It may be time for an air conditioning inspection.

Closing Vents Will Save Me Money by Pushing Cold Air to Other Rooms

Not true. Air conditioning systems are based on balance and pressure. By shutting off one room, you are creating an imbalance in the entire system which does not help and in fact, hinders the effective cooling of your home overall.

If You Wait Long Enough, That Weird Noise Will Go Away

This is one of those enduring myths in life which starts with a different version in childhood. If I hide under the covers, and keep my eyes shut, the monster under the bed won’t be able to get me. If your air conditioning unit is making a horrendous noise when it starts up, it’ll probably work itself out if I just let it run long enough. Sorry, both are not true. Ignoring warning signs from your AC unit can lead to bigger problems down the road.

Service Contracts Are a Bad Idea

In Arizona, where air conditioners are pushed to extremes every summer, service contracts are a wise idea. Like your car, it doesn’t make sense to drive your air conditioning unit as hard as you can for years in a row without service. It’s bound to break down. Don’t be fooled by air conditioning myths. And, don’t take chances with your home comfort. Call Cool Blew today.
