When Should You Turn on Your Air Conditioner?

This entry was posted in Air Conditioning on by .

We all know that spring-like weather starts early in Arizona. And this year is no exception. Temperatures are already starting to creep back up above 80 degrees. Although nights and mornings can still be chilly, many of us are tempted to turn on the air conditioner in the afternoon to cool off a bit. But before you touch that thermostat (and long before that first 100-degree day hits), it’s important to ensure your air conditioner is working optimally.

Spring Cleaning for Your AC

Like with the rest of your home, your air conditioner requires maintenance to stay in tip-top shape. Early spring is the ideal time to make sure it’s clean. This includes replacing or cleaning air filters, cleaning up dirt and debris around the exterior unit and cleaning the coil and condensate drain. If you don’t feel comfortable with any of these tasks, the team at Cool Blew is happy to help as part of preventive maintenance service.

Professional Tune Up

As part of preventive maintenance, you will also gain the advantage of having an expert technician ensure every component of your air conditioner is working optimally. If malfunctions are identified, they can be fixed in a timely manner. This means not having to experience an unexpected system failure on a summer day when cooling is critical. Even if you think your air conditioner is working fine, it makes sense to schedule a tune-up with an HVAC professional. And spring is the optimal time before the busy summer season begins.

Considering a New Air Conditioner?

If you’ve been putting off replacing an aging, inefficient system, we can help you with that, too. We provide free in-home estimates and can help you determine the best system for your specific needs. A new air conditioner will save you a substantial amount on your monthly utility bill and will improve your home’s comfort considerably.

Replace the Air Conditioner or Just the Evaporator Coil?

This entry was posted in Air Conditioning on by .

In the Valley of the Sun, weather can be tough on air conditioners. While they can run for many years without missing a beat, the elements can eventually begin to erode components – including the evaporator coils. When this happens, the refrigerant that flows through the coils can begin to leak. This is a significant repair, and often it makes sense to simply replace the unit. But this isn’t always the case.

Signs of Evaporator Coil Problems

  • Loss of cooling power
  • Registers not blowing cool air
  • Hissing sounds from the unit
  • Rising electric bills

Reasons to Replace the Unit

Your AC is 10 years or older – If you have a unit that is approaching the end of its life (10 years or older), it typically makes sense to go with replacement because of the increase in efficiency that you will gain with a newer model. Here’s another way to think about it. Replacing just the evaporator coils in an old unit is akin to replacing the engine in a car with 150,000 miles on it. It just doesn’t make sense.

Your AC uses R-22 (Freon) – If you have a very old unit that uses the now banned R-22 refrigerant (Freon), replacement is a no-brainer. This type of refrigerant is no longer being produced, which means it’s in limited supply and increasingly expensive. Regardless if it’s a problem with the coils or any other type of refrigerant leak, unit replacement is the way to go if your unit takes R-22.

The evaporator coil you need is obsolete – If you have a unit with a low SEER rating, the replacement coil may no longer be available. Mismatched coils can drag down the performance of your unit and ultimately cause a full system breakdown.

Think you may have an evaporator coil problem with your air conditioner? Considering a new unit? Call the experts at Cool Blew today.

Maximize Your Air Conditioner Efficiency in 2020

This entry was posted in HVAC Maintenance on by .

While most of us aren’t running our air conditioners in February, there’s no disputing that they are essential throughout most of the year in Arizona. So, it’s a good thing that they’re built to last and work reliably for years.

Yet, like all good things, air conditioners can be taken for granted. Most work without a problem, even in extreme heat, without missing a beat. But, if they are neglected or not properly maintained, problems can happen.

The Time to Call Is Before There’s an Issue

Consider that your air conditioning system has many components – both inside and outside of your home. These include motors, switches, fans, vents and more. They all work together to generate comfortable, cool air. Keeping this mechanical and electronic symphony playing in harmony requires regular, preventive maintenance.

Choose a Trusted Provider of Air Conditioning Maintenance and Repair

Today’s air conditioners are complicated. You want an HVAC service provider that is both highly trained and experienced. Establish a relationship so that the provider can get to know your HVAC system. The goal is to get in the habit of twice-yearly service inspections (ideally in the spring and fall), so that you don’t have breakdowns in the hot summer months or in the chill of winter. Yes, air conditioners, as well as other HVAC, parts and components can wear out or malfunction – and at different times. With regular maintenance, potential problems can be identified proactively, and parts replaced before you experience a problem.

Don’t Forget Your Ductwork

In the dusty environment that we live in, ductwork isn’t something to ignore. Ducts are vital for delivering conditioned air to every room in your house. So, if they’re loaded with dirt or mold, you and your loved ones are breathing that in. As part of HVAC system efficiency and upkeep, make sure that your ducts are checked and cleaned.

Let Us Perform a Complete Inspection and Evaluation of Your HVAC System

Make 2020 the year for an air conditioner reset. Let Cool Blew help you maximize the efficiency and effectiveness of your air conditioner and entire HVAC system. Call us to schedule a tune-up and inspection today!

Is Your Heat Pump Leaking Refrigerant?

This entry was posted in HVAC Maintenance on by .

Just like your refrigerator and air conditioner, a heat pump requires refrigerant to work. Yet unfortunately, many homeowners don’t discover that their heat pump’s refrigerant levels are low until they’re experiencing a problem like icing or no heat.

Is It a Leaking Heat Pump?

Within your HVAC system, your air conditioner and heat pump both rely on refrigerant to provide an optimal temperature inside your home. And, it shouldn’t dissipate during operation. Instead, your HVAC system should convert refrigerant from liquid to gas and vice versa – never decreasing in volume. However, leaks can happen, and they often occur at connector points.

During the cold winter months, often the first sign of a refrigerant leak is an indoor temperature that begins to drop. You may notice that the heater seems to be running continuously. Yet, the temperature doesn’t seem to be matching the thermostat setting. If it’s getting chilly, and the heat doesn’t seem to be where it should be, it’s time to call for a technician.

What About Icing?

When a heat pump is leaking refrigerant, there’s often a snowball effect of problems. The first of these can be the heat pump’s evaporator coil. Because heat absorption is the refrigerant’s purpose, leaking refrigerant can prevent the coil from absorbing heat. This ultimately causes moisture on the evaporator coil to ice over. You may be tempted to scrape off the ice but note that this isn’t going to solve the problem. What you actually need to do is call an HVAC technician who can both seal the leak and add the necessary refrigerant to enable your system to operate efficiently.

Don’t Neglect a Refrigerant Leak

Low refrigerant isn’t an HVAC problem to put off for another day. The stress caused by this problem can leave you in the cold, as well as impact the compressor and drive up electrical costs. If you’re struggling with a lack of heat, call the experts at Cool Blew. We’re here to help you identify the cause of the problem and ensure that you’re up and running as quickly as possible.

Is Your Thermostat the Problem?

This entry was posted in HVAC Maintenance on by .

When your heater is not quite getting the job done and you’re feeling an uncomfortable chill in your indoor air, it’s natural to think there’s a problem with your furnace or heat pump. And, the unit could certainly be the culprit. But, it’s important to understand that a heating system is made up of a group of components that work together. And, if one is malfunctioning, it can cause a system-wide problem. Sometimes, the problem is one that often gets overlooked – the thermostat. Even minor thermostat problems can have an impact on your comfort and cause your utility bills to soar.

Poorly Placed Thermostats

If you’ve been struggling with HVAC challenges for a while, the problem may be with your thermostat’s installation. Often, we find that the device has simply been installed in the wrong part of a house. It should be located near the center of your home so that it’s accurately picking up the average temperature rather than the highest of highs and lowest of lows. Thermostats placed near direct sunlight or drafty doors or windows can pick up false readings and cause your heater to either work overtime or not at all.


One of the most common thermostat issues is miscalibration. There is a sensor in the wall unit of your thermostat that should accurately read the temperature inside your home. Even if it’s off just a couple of degrees, it can increase energy bills and affect your comfort. Indicators of this type of problem are a heating system that runs too long or not long enough. The good news is that the experts at Cool Blew can recalibrate your thermostat quickly and get you back to an accurate reading.

Connection Failure

Thermostats are connected to your heater or air handler via wires that control when the heater and the blower motor turn on and off. If these connections are lost, you’re going to experience problems. Again, this is a common problem that we’re well-versed in repairing.

Old Thermostat

Do you still have a manual thermostat that uses sliders and dials or a stripped-down digital model? If so, you’re not getting the maximum value of your heating system. Smart, programmable thermostats offer tremendously improved control and energy savings over the older models. And, they can be conveniently controlled via an app on a phone or tablet. Don’t miss out on this technological advancement that delivers tremendous benefits in your home.

At Cool Blew, we’re focused on your comfort. Call us for heating and thermostat repairs 24/7/365.

Humidity and Your Home

This entry was posted in Indoor Air Quality (IAQ) on by .

Low indoor air humidity can be a challenge in the winter months for homeowners. Dry air can impact nasal passages, mucus membranes, throats, eyes and skin. It can also dry out wood, paint and other surfaces.

In ideal circumstances, indoor humidity should hover between 40 and 50 percent. Yet, keeping it at that level can be a challenge unless you’re taking steps to regulate the humidity. One option is a room humidifier. This is a small freestanding appliance that plugs into a standard outlet. They can be placed on the floor or on a table or countertop to deliver humidity directly where you’re located without wasting energy on empty spaces.

Today’s humidifiers come with a host of features including cool and warm mist, timers and features to trap contagions. They are inexpensive, portable and easy-to-use. However, they do require regular maintenance to keep them clean. Stagnant air left in a humidifier can become an ideal breeding ground for mold and bacteria.

An alternative to a room humidifier is a whole house humidifier which is an evaporative unit that is part of your HVAC system. Attached directly to your home’s ductwork, it blows vapor through the air ducts evenly throughout each room of a home. Whole house humidifiers also monitor your indoor humidity by measuring the moisture in the air and can operate either manually or automatically based on settings.

Unlike portable humidifiers, whole home humidifiers require little maintenance. There is no risk of lingering moisture so there is no way for mold or bacteria to grow. They are also highly energy efficient and quiet.

Both room humidifiers and whole house humidifiers tackle the same issue of dry air but in slightly different ways. However, both have the ability to increase your home comfort. Learn more about indoor humidity from the experts at Cool Blew.

Improve Your Home’s Value and Comfort with These Electrical Improvements

This entry was posted in Electrical on by .

Just venture into your local home improvement store, and you’ll be bombarded by a bevy of options to enhance the aesthetics of your home. Everything from new flooring to the latest paint shade can add value and pizzazz to your residence. Yet, one of the most impactful improvements that you can make is often overlooked. By focusing on home electrical improvements, you can not only improve the look of your home, but also increase its value and comfort.

  • Fans

    The days of brass and fake wood ceiling fans are thankfully over. Today’s fans come in a wide variety of styles that can fit everything from an Asian-inspired bungalow to an ultra-modern loft. The key is choosing one that fits your room and offers the low-cost cooling that you’re looking for. Whatever style you settle on, remember that ceiling fans are well worth the investment and should be used in living rooms, bedrooms and more because of their ability to help control AC costs.

  • Pendant Light Fixtures

    Choosing pendant light fixtures can definitely jazz up the look of a kitchen, dining space or office. They also create ambiance and can be matched with whatever décor you have. From retro to classic style, you can find pendant lighting to complement your décor.

  • Dimmer Switches

    Turn a ho-hum room into a romantic space while lowering electrical costs by dimming the lights. In fact, the use of dimmer switches in your home can save up to 10 percent on your energy bill while reducing the wear and tear on lighting and bulbs.

  • Smart Technology

    The Internet of Things has hit the residential market – and in a big way! Smart technology is being incorporated into lights, thermostats, appliances and even plumbing to make your home more functional and energy efficient.

Temperature Tussles – Couples Who Thermostatically Disagree

This entry was posted in Heating on by .

The concept that opposites attract has been featured in many poems, songs and movies. To be sure, relationships run hot and cold. However, when it comes to room temperature and thermostat settings, many couples have strongly differing opinions. Even though there’s little science to support it, in many cases, the guy would like it to be cooler, and she can never get warm. Because it is so central to comfortable living, temperature sensitivity can sometimes cause discord in the home.

Is Temperature Perception a Scientific Fact or a Matter of Opinion?

Do men and women maintain the same core body temperature under controlled circumstances? As we all know, internal body temperature for humans, men and women, hovers around 98.6 degrees. The National Institute of Health (NIH) asserts differences do arise within various groups depending on age, race, gender and physical condition. The main point is, when it comes to temperature, it’s all about perception – how your body perceives the atmosphere around you. Factors such as body weight, muscle mass, level of activity, person metabolism all contribute to feeling warm, hot, or cold. So, a “perfect” 70 degrees affect you one way and your spouse, another.

January is the coldest month of the year in Phoenix. As temperatures drop and night’s dip below freezing, waking up to a cold house can be bothersome. Unfortunately, cranking up the heat all night can get expensive. Here are some options which will give you more control over the temperature in your home:

  • Smart Thermostats Make Your Life Easier

    If you have an older, single thermostat located in one part of your home, it may be time for an upgrade. New Wi-fi enabled “smart” thermostats save you money and allow you to heat your home more efficiently by making it easy to tailor temperature settings throughout day and night. These digital wonders actually learn your schedule and tendencies and adjust accordingly. You can install multiple smart thermostats throughout different areas of your house, so they communicate with each other. This is especially important for expansive homes with a furnace on one end of the house and bedrooms on the opposite side of the house. It’s important to remember, various brands will provide different options. Our friendly service techs will be happy to explain the advantages to you.

  • Zone Heating and Cooling

    By creating separate, dedicated areas, zone heating and cooling allows you to adjust individual rooms to a higher or lower temperature depending on how you or your spouse (or children) prefer it. If you’d like your master suite to be 5 degrees warmer 30 minutes before you wake up, just program it in. Zone heating and cooling puts tremendous control in the homeowner’s hands.

  • Increased Efficiency of Your Current HVAC System

    When people experience temperature fluctuations from room to room, they are often surprised to find that an HVAC system inspection may reveal certain problems or deficiencies which can be repaired and remedied quickly. Over the years, we’ve found disconnected or crushed air ducts, faulty fans, gaping leaks or holes and all other kinds of impairments to free-flowing air. If your system has not been checked lately or if it has been years since your ducts and vents were inspected, please give us a call.

Let Our HVAC Experts Solve Your Temperature Tussles

Our experienced technicians will review your entire HVAC system and solve the mystery of fluctuating temperatures from room to room. We will be happy to discuss your heating and cooling challenges with you. We’ll prepare a detailed HVAC plan to end your temperature tussles once and for all. Why not give us a call today.

8 Plumbing New Year’s Resolutions for 2020

This entry was posted in Plumbing on by .

With Christmas over, our thoughts turn to the new decade ahead and New Year’s resolutions. Of course, we all want to exercise more, spend less and enjoy each and every day in 2020. But, you may want to add a few plumbing-related resolutions to your list, too. Not only will they help improve your home’s comfort-level, they can save you money by reducing your water consumption.

Here are eight plumbing resolutions that every homeowner should try and stick to:

  1. Proactively fix leaky faucets, toilets and clogged drains before they become bigger, more costly plumbing problems.
  2. Only put human waste and toilet paper down the toilet. Nothing else – ever!
  3. Turn off water while shaving and brushing teeth.
  4. Run the dishwasher and washing machine only when there is a full load.
  5. Use drain guards to prevent harmful material from sliding down drains.
  6. Consider installing a water filter and/or softener. Although we’re fortunate enough to enjoy clean, drinkable water, the quality can be significantly improved with the addition of a whole house water filter or softener.
  7. Flush your water heater and have it professionally inspected at least once a year. Don’t forget that Arizona’s hard water can really wreak havoc on water heater tanks.
  8. Consider having your sewer line rodded to prevent an inconvenient and costly backup.

Here in the desert, water is our most precious natural resource. We can’t live without it, and there’s a limited supply. We encourage you throughout the year to follow these resolutions and to share them with family, neighbors and friends. Together, we can all help our environment.

And don’t forget to call us at 623-872-2900 for any and all of your plumbing needs in 2020. At Cool Blew, we’re your go-to provider of professional plumbing service throughout the Valley.

Happy New Year from our family to yours!

Emergency HVAC Call from the North Pole

This entry was posted in HVAC Systems on by .

We recently received an emergency call from the North Pole. It seems a certain S. Claus is having trouble with the furnace in his workshop, and his elves are getting cranky. They’re shivering and sneezing, coughing and wheezing and planning a work stoppage – which would be disastrous. You might say their relationship with their employer has grown a little frosty. “Do you work over the holidays?” Mr. Claus inquired. We told him our lines are always open – 24/7, 365 days a year. And that goes for anyone in the Valley who might need our services over the holiday season.

We Pause to Reflect

During this time of year, we like to take the time to reflect on our many blessings. Arizona is a special place, and we feel lucky to live and work here. As reports of arctic blasts and winter snowstorms keep our northern neighbors indoors, we smile and say, “Looks like another perfect day in the Valley.” We’re happy to be here. We love working on heating and air conditioning issues. Every system is different, each presenting its own unique challenge. Believe it or not, providing truly great HVAC service is like figuring out a series of interesting puzzles every day. Our job never gets boring.

At Cool Blew, We’re Grateful for You

Many good things have happened this year. We are, most of all, grateful for you, our wonderful customers. All that we have and all that we do is because of you. We never forget that you are the very reason our company exists. We’re grateful that this area has prospered and grown. We’re happy the phone never stops ringing, and service requests keep coming in. Thanks for another great year!

If You Need Us Over the Holidays – We’re Here

The next few weeks will be filled with family, fun and good cheer! We hope you don’t need service on your HVAC system, but if something goes wrong – we’re always here. We wish you and your family all the best over the holidays. We’ll take care of Santa – you have a blast!
