What Is an Urban Heat Island and How Does It Affect You and Your Air Conditioner?

This entry was posted in Air Conditioning on by .

Phoenix residents know the drill during a heatwave. When the temperature climbs above 105, you do what you can to avoid being outside during the hottest part of the day. Occasionally, you may find yourself walking down a city street or making your way across a scorching, treeless parking lot. It’s then you realize what the term, “urban heat island” means. In the highly developed, greater Phoenix area, asphalt, concrete, metal and hardscape stone and gravel combine to absorb and then release the heat of the sun, often adding up to ten degrees of temperature during any given day. Urban heat island effect also keeps the entire city temperature warmer in the night. When you have the equivalent of three months of 100+ temperatures, that adds up to a lot of extra stress on your air conditioner – and on you!

Extreme Temperatures in Phoenix – The Heat Is Coming

So far this year, temperatures have been relatively moderate. With July, August and September just ahead, triple digit heat will be coming soon. Most desert dwellers are well aware of normal heatwave precautions. Drink plenty of water. Always keep extra water bottles in your car. Do your workouts or dog walking early in the morning. Protect yourself from the sun. Don’t forget sunglasses, hats and baseball caps. Keep sun block handy (especially for the kids, who don’t always want it.) Stay indoors during the afternoons and if you suffer from asthma or a respiratory condition, try not to exert yourself.

Here are few a precautions for your air conditioner:

  • Check Your Air Filters

    Your air filters form the first line of defense in your home against dust, pet dander, particulates and VOC’s (volatile organic compounds). Did you know that indoor air pollution can be worse than outside air? If you haven’t checked your air filters in a while, it’s a good idea to replace them before the big dust storms of monsoon season hit.

  • Clear the Area Around Your Air Conditioner

    If you haven’t done so already, take time to inspect the area around your air conditioner to make sure it’s free from obstruction and not overgrown with grass, bushes or tree branches. Free flowing air around your air conditioner makes the transfer of heat away from your home easier.

  • Schedule an Early Summer HVAC Checkup

    We recommend two service calls per year. One in spring to prepare for summer and another in fall. Our friendly service technicians will perform a full system inspection and make sure your air conditioner is ready for the hottest days of summer, which are just ahead. Remember, it is important to have your refrigerant checked (at the very least) once per year, as well as all the other critical parts of your AC system.

Your Home Will Be an Oasis of Cool Amid the Phoenix Urban Heat Island

When the heatwaves hit and the temperature climbs well above 100 degrees, our phone rings off the wall. Don’t wait until your air conditioner breaks down to schedule service. Be proactive and give yourself and your family the gift of cool AC all summer long. Call us today.

Air Conditioning for Your New House or an Addition to Your Home

This entry was posted in Air Conditioning on by .

Population in the Southwest has grown tremendously over the last four decades. The Phoenix-Mesa-Scottsdale metropolitan area now has over 4.7 million people. In fact, just last year 25,000 new residents moved into Phoenix, bringing the total population to 1.7 million, making Phoenix the fifth largest city in the United States. New home construction is everywhere. Building and development is a way of life. If you’re in the exciting process of building a new home or if you are adding a significant addition to your existing home, there’s one crucial element of design that doesn’t always receive the attention it deserves. In Arizona, air conditioning is crucial to the enjoyment of a living space. However, it’s not always a top priority during the design and planning phase, especially for home additions.

Air Conditioning Is Crucial

When it comes to construction, architects and builders know, it’s visuals and design that sells a project. Less visible details, such as air conditioner location, duct work and vent placement can be seen as secondary. However, the extreme desert heat means your air conditioner is not only crucial for comfortable living, it’s also something you pay dearly for in terms of monthly utility bills. Poor planning and design can lead to sub-standard or inefficient cooling which may mean paying more to cool your home or addition. Here are a few HVAC points to consider in planning your new home or addition:

  • Get the HVAC Experts (That’s Us) Involved Early in the Design Process

    Of course we believe air conditioning should be a top priority for your home – it’s what we do! However, day in and day out we find ourselves repairing or re-engineering mistakes made by builders who are not qualified to design HVAC systems. That is especially true for room or wing addition projects. Get us involved early in the design process, before you get to final plans.

  • Options for Room Additions

    There are generally three options for master suites or room additions. They include utilizing and extending your current system, upgrading to a new, larger air conditioner or adding an independent system. A load calculation will need to be performed and your current system should be thoroughly assessed.

  • Schedule an HVAC Inspection and Consultation

    Whether you’re involved in building a new house or putting an addition on your existing home, scheduling an HVAC expert to meet with you will give you peace of mind going forward in your project. We deal with the results of poor HVAC planning every day. When it comes to properly cooling your home, knowledge and experience make a huge difference.

We’ll Help You Achieve the Best HVAC Solutions for Your New Home or Addition

Building a new home or overseeing an addition is a huge undertaking. For the comfort of your family, make sure air conditioning is a priority right from the start – not an afterthought. Our experienced professionals will provide you with the information you need and help you every step of the way. Why not call us today?

Will Your Air Conditioner Last Through the Summer of 2019 – 3 Key Questions to Ask

This entry was posted in Air Conditioning on by .

Typical Phoenix temperatures in early June hover in the nineties. As July approaches and triple digit heat descends on the Valley, you have to ask yourself one important question – is your air conditioner going to make it through the hottest months of the year? In 2018, there were over 128 days with temperatures above 100 degrees. This July, August and September will push your air conditioner to its very limits. If you had AC issues last summer or if you’re air conditioner is making funny noises, not cooling properly or just plain making you nervous, here are three questions to ask in considering if now is the right time to replace rather than repair. It’s important to remember, replacing your air conditioner during the hottest part of the summer is an option you want to avoid if at all possible.

  • How Old Is Your Current Air Conditioner?

    Manufactured to last a long time, in most parts of the U.S., air conditioners can last 10 to 15 years. However, in Phoenix, the hottest city in America, air conditioners have a shorter life span and generally provide reliable service up to 8 years. Not unlike an automobile with high mileage, desert air conditioners log heavy usage year in and year out. Dust storms and monsoons can take their toll and rooftop air conditioning units operate in intense sunlight with punishing UV rays and temperatures exceeding 140 degrees. To determine the age of your air conditioner, check your original AC invoice or warranty papers to determine if you have them. If you purchased your home more recently and have no idea how old your AC unit is, our service techs can usually figure it out based on the general condition of the air conditioner and reviewing the manufacturer’s model number and information.

  • How Much Have You Spent on Repairs in the Last Two Years?

    As air conditioners get older, more and more repairs are required to keep the unit running in top form. Major repairs, such as replacing the condenser, can be very expensive. If your AC unit is over eight years old and you’ve started to notice major repairs over the last two years, it may be time to replace. One typical guideline is if repairs are going to exceed one third of the cost of a new unit within a two-year period and your air conditioner is over 8 years old, you are probably better off replacing rather than continuously repairing your unit.

  • How Much Is Peace of Mind Worth?

    We understand that replacing an air conditioning unit represents a significant expenditure for homeowners. We don’t take this decision lightly. We pride ourselves on providing excellent service which ensures air conditioning units will last as long as they possibly can. However, when an air conditioner is approaching the end of its useful life, we generally advise, getting the new unit installed before the very hottest part of summer. We replace air conditioners all throughout the year and we are happy to do so. It’s simply more comfortable for homeowners to have trouble free AC without interruption through the months of July, August and September. Over the years, we’ve had many situations where customers tried to squeeze another year of service out of their AC unit and it unfortunately died at the very worst time imaginable.

  • Is It Time to Replace Your AC Unit?

    If your air conditioner is faltering, why not schedule a service call to determine what’s best for the hot summer ahead? Our professional and friendly service technicians have years of experience and will provide you with the information you need to decide if your AC unit is all set for the summer of 2019.

Countdown to Monsoon: Preparing Your Phoenix Home for Summer Storms

This entry was posted in Air Conditioning on by .

Throughout the fall, winter and spring, the weather throughout the greater Phoenix area is the envy of the country. Yet, things can become less than desirable during the summer months when temperatures soar, and monsoon conditions take shape. High winds, walls of dust, downpours of rain and plenty of lightning and thunder can be exciting to watch but also damaging to your home. Yet, with a few precautions, you can protect your home from severe weather that can unexpectedly hit from mid-June through late September.

Protect Your Air Conditioner

Your outdoor air conditioning unit is vulnerable to damage during severe summer storms. A simple way to protect this vital and valuable piece of equipment is to trim back all the brush, trees and landscaping around it. The greatest risks during monsoon weather conditions are falling trees and blowing branches and leaves. They can both damage the unit from impact, as well as blow debris that can get lodged inside it.

As well, grass, brush and weeds can flood into the lower components of the system which can restrict airflow, clog coils and hinder the function of the system. Before the monsoon hits, take a few minutes to cut back vegetation and clean up all clippings to keep the area around your unit as clear and clean as possible.

Invest in a Surge Protector

With severe storms come plenty of lightning strikes. If one hits your home, you could experience an electrical surge which can damage your electronics and electrical systems. With a whole house surge protector, you can protect your HVAC system, as well as all the important electrical equipment that you rely on each and every day.

Schedule Air Conditioning Maintenance Today

At Cool Blew, we recommend Phoenix-area residents to have their HVAC system maintained. Before monsoon season is an ideal time to ensure your system is running efficiently and effectively.

With regular maintenance, you’ll be able to better manage summer electrical bills, correct small issues before they become costly repairs and prevent breakdowns before they happen.

Schedule your maintenance today. We’ll send out an experienced technician who can help provide peace of mind to you throughout monsoon season and beyond.

Dust Mites Just Might Be Aggravating Your Allergies and How Your Air Conditioner Can Help

This entry was posted in Air Conditioning on by .

Springtime in Arizona is often referred to as allergy sneezin’ – er, season. If you’ve been suffering from itchy, watery eyes, a runny nose and labored breathing, it could be from the pollen and ragweed found floating in the air this time of year. However, if your symptoms extend beyond spring, remember, not everyone suffers from hay fever. Some individuals are allergic to dust. For all its beauty, the desert is one extremely dusty place to live. If you’ve observed dust storms darkening the sky a mile high and blotting out the sun, you understand there’s some serious dust swirling around the Phoenix metroplex. Unfortunately, some of that dust finds its way into your home.

What Is Dust Made Of?

Have you ever been vacuuming and noticed a shaft of golden sunlight shining through your window to reveal an alarming amount of dust particles suspended in the air in your home? Though it largely goes unnoticed, left unchecked, dust in your home will build up quickly. Dust is comprised of fine dirt, tiny grains of sand, flaked skin cells, pet dander, small hairs, bits of threads, minute pieces of cotton fabric, pollution from automobile exhaust and even a little cosmic dust which falls to earth from the atmosphere. Microscopic dust mites live on human skin, animal dander and fungal spores. We’ve had astonished customers ask us, “You mean to tell me all this is inside my home?” The answer is yes. Incredibly, often the air quality inside your home is worse than the air outside. Here are steps you can take to minimize dust in your home, reduce your allergic reactions and improve your indoor air quality:

  • Change Your Air Filters Regularly – With the doors and windows closed, your home becomes, more or less, a closed system. Of course, dust and air pollution will get in when you open the doors. However, for most of the summer, your doors and windows remain closed all summer long to keep out the severe heat. Your greatest safeguard against dust is the air filter in your air conditioning system. As air from your home is recirculated through your AC system, the air filter helps remove all the little nasty little particulates listed above. If your air filters become clogged with dust and dirt, their effectiveness is greatly reduced, and more dust will circulate through your home.
  • Have Your Air Ducts Cleaned – Dust and dirt can accumulate in your air ducts. Many homeowners have no idea of the condition of their air ducts because they’ve never seen inside them. In many Phoenix homes, the ducts have never been cleaned. A duct inspection will also reveal if there’s any water collecting inside your ducts, which can cause mold and a faint, foul odor.
  • Consider an Added Air Filtration System Utilizing UV Lights – Ultra-violet lights add extra protection in that they eradicate biological contaminants from the dust in your air. If you or a family member is suffering from respiratory distress, this might be an option to explore. Our service technicians can review your present system and explain how UV light technology works.

Monsoon Season and Haboobs (Dust Storms) Will Be Coming Soon

Summer will be here before you know it. That means triple digit temperatures and dust storms accompanying monsoons. Now is the perfect time to have your air conditioning system checked and serviced, before the extreme weather hits. Give us a call, and we’ll be happy to schedule a service call to get you ready for the summer.

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.
