How to Calculate the True Cost of Your HVAC

This entry was posted in HVAC Systems on by .


Arizona homeowners understand the critical nature of having trouble-free, reliable air conditioning all summer long. And yes, studies have shown, temperatures in the Southwest are getting hotter, and summers are getting longer. As CEO of your household, you are called upon to make all kinds of decisions. From the seemingly insignificant to major improvements, such as when to replace your HVAC. It’s your job to do the research and allocate your resources wisely. Choosing the right time to install a new HVAC system will make the difference between a cool, carefree summer or a series of HVAC mishaps requiring service while you swelter in the heat. Because of the lower temperatures and lighter workload in the winter, the months between January and March are ideal for a new system installation. If you’re considering replacing your HVAC system in 2019, calculating your energy costs can be an important factor in making the right decision.

Energy Costs Continue to Go Up

Utility bills and energy costs are a significant part of any family’s budget. In 2017, Arizona state utility regulators approved a $95 million rate hike for APS, which was later challenged in court and featured heavily on the news. The US Department of Energy says air conditioning can account for more than half of the monthly energy use in a typical home and up to 70 percent in hotter climates. You need only review your own electric bill to understand the trend is headed one way – up. To calculate how much you are spending each month to cool your home, the US Department of Energy has created this Energy and Cost-Savings Calculators for Energy-Efficient Products.

What Is the Life Span of a Typical Air Conditioner?

HVAC units are built to last a long time. In moderate climates, some units provide service for 10 years or more. However, summers in Arizona are extremely tough on hard working air conditioners. A typical life span for an air conditioner running nonstop in the desert would be approximately seven to eight years. Depending on when your home was built and when your air conditioner was installed, your AC unit may be nearing the end of its useful life. You’ll know it’s time to consider purchasing a new air conditioner when the service calls and maintenance bills start piling up.

SEER Ratings, BTUs and Air Conditioners

SEER ratings provide guidelines for energy efficiency. If you have an older air conditioner, the SEER rating may be six or lower. Purchasing an AC unit with a higher SEER rating means a more efficient use of energy to displace heat in the process of cooling your home. That’s how a new, energy efficient AC unit can save you money on your electric bill. The higher the SEER rating, the better. BTUs stands for British thermal units, which in simplified terms, is a standard of measurement for the amount of heat your air conditioner can remove from a given room or area. The higher the BTU rating, the more cooling power of the air conditioner. At first glance, these calculations may seem a bit confusing. Give us a call to schedule an overall HVAC consultation, and we’ll be happy to explain the fine points of saving you money on your utility bills.

HVAC Holiday Gift Ideas

This entry was posted in HVAC Systems on by .


With the holidays here, the December ritual of finding something unique for family members poses a puzzle that an army of elves can’t solve. Hold the socks with the whacky designs and skip the last-minute scarves. Leave the goofy battery powered sweaters in the bin and just say no to another bottle of celebrity perfume. Consider a climate comfort alternative instead!

Temperature Affects Every Aspect of Our Lives

At first glance, heating and air conditioning gifts may seem a bit unusual. After all, desert temperatures in December are moderate and delightful. However, when you consider how much time Arizonans spend indoors (over 90 percent in the summer months) and just how important temperature is to personal comfort, then it starts to make sense. If you’ve got someone in your life who’s always a little too hot or too cold, giving the gift of temperature control could be just the right move.

HVAC-Related Gifts – The Sleeper Hit of the Year

This year, why not give a gift that truly keeps on giving all year long. Consider these offerings for the temperature sensitive VIP in your life.

  • Wi-fi Enabled Smart Thermostat – Creating a comfortable home environment starts with your thermostat. Because most thermostats are extremely reliable, homeowners rarely think about replacing them. However, new smart thermostats give you more control over your HVAC, allow you to heat or cool your home more efficiently, help you save money on energy costs and even let you adjust settings from your phone. Sounds like a great tech gift for dad that the whole family will enjoy.
  • Ceiling Fans – If you struggle with heat during the summer, installing ceiling fans can make a huge difference. Ceiling fans not only make rooms more comfortable to be in, they also help reduce your utility bill. Though ceiling fans do not actually lower the temperature in a given room, they make you feel cooler by moving air across your skin. Ceiling fans come in a multitude of styles, shapes and sizes and will add value to your home.
  • Cooling Mattress Pads – The recent rise of popularity in memory foam mattresses has brought along an unintended consequence. At night, as you sink into the memory foam, your body tends to generate more heat because there’s less air moving around your skin for cooling. Hi tech cooling mattress pads are the answer. This is a “cool” gift for anyone who perspires while sleeping.
  • All New HVAC System – Depending on how old your air conditioner is, it may be time for an all new HVAC system. This is understandably a large purchase and would definitely not fit under the Christmas tree. However, the winter months are the best time to install a new system, so you’ll be cool and worry-free when the hot weather comes along in spring. If you’re not ready to replace the entire system, you can always get dad a new set of air filters just for fun!

Furnace Foresight – Preventive Maintenance on Your Heating System Saves Time and Money

This entry was posted in HVAC Maintenance on by .


Imagine an appliance that doesn’t get a tremendous amount of use, rarely causes problems, works year in and year out and almost never seems to need service. For many Phoenix homeowners, that describes their furnace. In Arizona, your furnace plays a distant second fiddle to the hardworking and all-important air conditioner. A summer without air conditioning is utterly unthinkable. However, Phoenix weather is so perfect during the winter months, some residents can go an entire season without turning their furnace on. This can lead to a bad case of FNS (Furnace Neglect Syndrome).

OK, so there’s not really a condition known as FNS, but it is true that many Arizonans take their furnace for granted and let years go by without having a service check performed.

Furnaces Are Built to Last Decades – What Could Possibly Go Wrong?

It is absolutely true that most furnaces are manufactured to very high standards and are extremely reliable. The fact that furnaces are so dependable can lull homeowners into a false sense of security. Here are the top five reasons to have your furnace inspected even if it appears to be working just fine:

  • Detect Carbon Monoxide Leaks – One of the most important reasons for a yearly furnace inspection is to check for carbon monoxide leaks – an odorless, colorless gas that can be potentially dangerous (even deadly) to you and your family. If you have a faulty heat exchanger or it becomes cracked, it’s possible for carbon monoxide to escape into your home. Our trained technicians will inspect your furnace to insure there are no carbon monoxide leaks.
  • Check Igniters and Clean the Burners – Whether you have an older gas furnace with a pilot light or a newer electronic ignition system, it is essential that the igniting sequence of your furnace works perfectly. If you notice a hesitation or delay in the ignition process of your furnace once it is turned on, your burners might need to be cleaned. Our technicians will inspect this crucial part of your furnace.
  • Inactivity Often Leads to a Dusty, Dirty Furnace – When your furnace sits inactive for many months, a year or even more, dust and dirt builds up and settles into the moving parts and fittings of your furnace. Occasionally rust will appear on the burners. You may notice the first time you fire up your furnace after months of inaction, there is a funny odor. That smell is the dust being burned off the exposed surfaces of your furnace. During a pre-winter inspection, our service techs will clean your furnace and get rid of excess dust and dirt, so it does not make its way into your home.
  • Thermostat Checkup – The key to proper home heating starts with your thermostat. We will check the calibration, the wiring and the accuracy of your thermostat and make sure it’s working properly. We will also provide you with information about new wi-fi enabled “smart” thermostats which can save you money and help you heat your home more efficiently.
  • Replace Dirty Filters with Clean Air Filters – Air filters keep your home free from indoor air pollutants, such as dust, dander and the fine desert dirt that tracks into your home. Replacing your air filters is a priority for any service inspection.

The Heat Is On

With Thanksgiving behind us and the new year just ahead, take the time to have your furnace checked before you experience any problems. Preventive maintenance detects and solves small problems before they turn into big headaches. Give us a call at 623-872-2900 and one of our expert technicians will inspect your furnace and your entire HVAC system for you.

Do You Need a Ductless Mini-Split System?

This entry was posted in HVAC Systems, Uncategorized on by .


Ductless mini-split systems are becoming increasingly common for good reason. They offer a range of benefits that are worth considering – especially if you struggle with temperature variances in your home or are looking for a simplified cooling/heating solution for a room that’s not connected to your HVAC system.

What Are Ductless Mini-Split Systems?

Mini-split systems have two parts. A unit is installed outside, called the condenser. There are models that only cool and those with a heat pump that offer both cooling and heat. The part of the system that gets installed inside your home on a wall is called an air handler. The temperature is adjusted by a remote control. Each air handler is referred to as a “zone.”

Unlike standard HVAC systems, mini-split systems don’t require ductwork. This means that systems can be installed in a number of places, like room additions, offices, converted attics and storage rooms.

The Benefits of a Ductless Mini-Split System

Quick and Simple Installation – A ductless system requires a relatively easy installation with no need to update existing ductwork or to cut into walls.
Temperature Control – With a ductless system, each room has its own system, so each person can have their desired temperature.
Reduces Humidity – Most mini-split systems have a dry mode feature to eliminate excess moisture from a room. This is particularly beneficial during monsoon season.
Lower Monthly Costs – If central air is cost-prohibitive in a new addition or other space within your home without ductwork, a smaller ductless system may be the answer. One condenser can handle up to four indoor air units.

Types of Mini-Split Systems

There are a variety of options when it comes to mini-split systems that are worth considering, including single-zone and multi-zone condenser units, ceiling cassettes and wall units.

At Cool Blew, we’re here to help you with all your heating and cooling needs. Call us today to learn more about ductless mini-split systems and to find out if this is a good option for your specific needs.

HVAC Air Filter Tips to Help You Breathe Easier

This entry was posted in HVAC Maintenance on by .


If you’ve ever forgotten to change your HVAC air filter for any length of time, you know just how much dust and dirt is collected. Air filters are vitally important to the function of your HVAC system. They not only trap particles that can hinder your breathing, they also help your system run more efficiently. So, it’s important to know the basics of air filters if you’re a homeowner.

Choose the Optimal Filters

First, it’s important to remember that not all filters are created equal. They range dramatically in terms of price, function and durability. The most common type of HVAC air filter is the fiberglass/synthetic type that is commonly found in home-improvement and grocery stores. They are able to catch about 80 percent of particles in the air that are 50 microns or larger. These products can help prevent the buildup of dust and dirt on heat exchangers, fan motors and other surfaces of your HVAC system, but they’re not the most effective type available.

Polyester filters are made with a higher quality material that remove up to 95 percent of particles 5 microns or larger. They’re about five times pricier than fiberglass/synthetic filters, but they are a solid choice if you’re continuously battling dust in your home. Pleated filters offer even greater efficiency by trapping particulates 0.3 microns in size, including viruses and bacteria. Electrostatic filters are another filter option, and they’re available in both disposable and washable models.

If you or other members of your household have allergies, asthma or other respiratory issues, HEPA filters may be the way to go. These capture 99 percent of particles 0.3 microns and larger. Yet, it’s important to remember that these premium filters cost more and slightly reduce the air flow in your HVAC system, which translates into higher utility costs.

Determine the Right Size

HVAC filters come in a variety of sizes. To ensure you get one that fits correctly, measure the air filter cabinet space or your existing filter. The most common filter sizes are:

10 X 20, 14 X 20, 16 X 24, 18 X 30, 12 X 12, 14 X 24, 16 X 25, 20 X 20, 12 X 20, 14 X 25, 18 X 18, 20 X 24, 12 X 24, 14 X 30, 18 X 20, 20 X 25, 12 X 30, 15 X 20, 18 X 24, 20 X 30, 12 X 36, 16 X 20, 18 X 25, 4 X 24 and 25 X 25

Replace Filters Often

In the desert, dust abounds, and it will collect in your HVAC system. This is why it’s vitally important to change out filters at least once a month to ensure your home’s air is clean and your system is functioning optimally.

Prepare and Protect Your Plumbing for the Holiday Season

This entry was posted in Plumbing on by .


There’s a lot to do before the holidays. Meal planning, housecleaning and decorating all come to mind. Yet, it’s easy to overlook one very important holiday checklist item – the plumbing. Yes, plumbing. The biggest day of the year for plumbers is the day after Thanksgiving, followed by the day after Christmas. Why? Plumbing emergencies tend to arise after a big holiday meal and when there’s a house full of guests. And, a leak or a clog is nothing to celebrate!

To avoid having to deal with an unexpected holiday hassle, here are some tips to help you prepare and protect your plumbing for the season:

  • Ensure bathrooms have a plunger and extra toilet paper before any guests arrive. Also, have a garbage can in every bathroom. This will help ensure that guests won’t be tempted to flush items that shouldn’t be placed in the toilet.
  • Watch what you put down the disposal. Food items like potato peels, pumpkin guts, egg shells, pasta, stringy vegetables, gravy, and grease should be thrown in the trash and not down the drain.
  • Check the water heater for leaks, rust or corrosion. Don’t take the chance of having hot water issues during the holidays.
  • Clear drain clogs in sinks and tubs. A simple plunge usually clears out small clogs. Larger ones may require the assistance of a plumber.
  • Address plumbing problems now before the guests arrive. Small issues like running toilets, minor leaks or unresolved shower clogs can turn into bigger problems that put a damper on holiday festivities.

Your Go-To Plumber During the Holidays and Throughout the Year

Hopefully, you will have a holiday free from any plumbing problems. But, if you do experience a leak, clog or other issue, you can rely on Cool Blew. With valley-wide emergency service, we’re here to help keep your holidays on track and running smoothly.

Heat Pump 411 – Everything You Wanted to Know About Heat Pumps

This entry was posted in Heating on by .


Many Phoenix area homeowners have questions about heat pumps. How does a heat pump differ from an air conditioner? Can a heat pump keep my home comfortable during the winter months? Is a heat pump the right choice for my home? Traditionally, in colder winter weather areas of the United States (the East Coast, Midwest and northern states) home heating and cooling systems are installed with two basic components – a gas furnace, as well as a separate air conditioning unit. However, in Arizona, many neighborhoods and outlying areas are without gas lines, so gas furnaces are not always an option. In many instances, heat pumps are the logical choice.

What Are the Differences Between Heat Pumps and Air Conditioners?

If you see an air conditioning unit sitting next to a heat pump in a showroom, they look the same. The inner workings are very similar with one major difference. An air conditioner can only cool your home by transferring the heat from inside your house to the outdoors (that is, of course, an oversimplification of the process of air conditioning). While a heat pump has the ability to reverse the process and extract heat from the outdoors and “pump” it into your home. Pump is not the ideal word in describing this process. Heat pumps “move” heat from one place to another rather than generate heat (which is what gas furnaces or electric heaters do.) Generating heat, whether utilizing gas or electric power can get costly. The good news is Phoenix winters are generally very mild with only a few cold snaps per year.

Is There More Than One Type of Heat Pump?

There are three main types of heat pumps; air source, split ductless and geothermal. Air source heat pumps are the most popular choice for Arizona homes and can reduce your heating bill significantly over old school electric baseboard heaters. Split ductless can be an excellent option for one room additions, garage workshops or a separate studio because they do not require any ductwork. Geothermal heat pumps can greatly reduce your home’s energy usage, but they require major upfront installation costs. There are advantages and disadvantages to each type of heat pump system. It’s a good idea to call in one of our experienced professionals to perform a complete HVAC inspection and assess your needs, review the options available to you and explain which system might work best for your home.

There are many reasons to consider choosing a heat pump for your home, including:

  • Heat Pumps Are Extremely Energy Efficient – A quote from the Department of Energy website states, “Today’s heat pump can reduce your electricity use for heating by approximately 50% compared to electric resistance heating such as furnaces and baseboard heaters. High-efficiency heat pumps also dehumidify better than standard central air conditioners, resulting in less energy usage and more cooling comfort in summer months.” Heat pumps yield more heat compared to the amount of electricity it takes to run them than older types of electric furnaces or heaters.
  • Cost – Which Is More Economical? – An expense comparison between a traditional AC/gas furnace house versus a home with a heat pump shows that over the course of one year, the cost works out to be just about the same. It is true that purchasing a heat pump with an extremely high SEER rating may be more expensive initially. However, there is no clear financial advantage to going with an air conditioner/gas furnace system over a heat pump.
  • Heat Pumps in Below Freezing Temperatures – People from all over the US visit Arizona from November through April because of the ideal desert climate. Temperatures in Phoenix are near perfect while the rest of the country bundles up for winter. However, occasionally temperatures will dip below freezing which can present a challenge for heat pumps. The solution is added heat strips which are electrically powered wire heating elements that warm up the air before it is blown into your home. Depending on how warm you like the temperature to be (especially in the mornings) your heat strip usage will vary.

Winter Is Coming

With the beautiful fall weather and relief from summer’s extreme heat, HVAC issues may be the last thing on your mind. However, November is a great month to schedule a fall checkup and review your options if you are considering a heat pump. Why not give us a call, and one of our friendly service pros will drop by and perform a full HVAC system assessment for you.

The “Fur” in Furnace and Other HVAC Animal Oddities

This entry was posted in HVAC Maintenance on by .


Many Phoenix homeowners schedule two HVAC maintenance checks per year. One in the spring to ensure the air conditioner is prepared for the grueling desert summer ahead and another in fall to prepare the HVAC system for winter. During the six months of Arizona summer, your idle furnace (depending on where it’s located) can make an attractive vacation home for squirrels, roof rats and other critters. During our fall checkups, we have found evidence of furry friends in furnaces and air vents. Unfortunately, rodents can find their way into very tight spaces. If you notice strange pitter-pattering noises in the middle of the night, you might have furry trespassers.

When Animals Invade

Many housing developments in the Phoenix metropolitan area are located near open spaces where animals abound. Even established neighborhoods are teeming with critters. It’s not uncommon for squirrels, rats and other rodents to seek refuge inside your outdoor HVAC unit or in your home via air ducts – many times gaining entrance through vents. Animals belong in the great outdoors. If your furnace or HVAC ducts have evidence of pests, it’s best to have us perform an entire system inspection and rid your house of these rodent intruders immediately.

Snakes and Spiders in Places They Don’t Belong

Phoenix residents have the added joy of occasionally discovering snakes and spiders in places they don’t belong. Snakes infrequently will make their way into the shade on the inside of an outdoor HVAC unit as well as black widow spiders spinning their webs on compressor hoses. We don’t report this to scare homeowners, but rather to let you know, over the years, we’ve seen just about everything. Always be cautious when uncovering an outdoor or utility room unit (or any HVAC unit) because you never know what you might find inside.

If you hear animals in your vents, or you see evidence of critters in or around your HVAC unit, the best solution is to call in professionals. Here’s a list of unwelcome visitors that may be trying to live in your HVAC system rent-free.

  • Squirrels and Raccoons – These are determined and ingenious creatures (particularly raccoons). They often find their way into your home through old, damaged, or faulty vents. You will likely hear them before you see them. If you notice foul odors from their droppings, call us immediately for service.
  • Mice and Rats – Small and crafty rodents can crawl into extremely small holes and spaces. They often cause damage by chewing on your refrigerant lines, electrical wires and other parts. Rats and mice love to pilfer insulation to build nests. Rodents present health risks for your family and need to be dealt with immediately. It is advised to clean and sanitize ducts if rodents have infested.
  • Spiders, Insects and Roaches – If you live in Arizona, spiders, insects and roaches are going to occasionally make their way into your home. It’s simply unavoidable. What we have noticed, over the years, is that certain areas are more susceptible to infestation if they have been ignored for long periods of time. Having regular inspections insures that your HVAC system won’t be overrun by creepy crawlers.

Living in the Desert

Close to Nature The beauty of Arizona is being so close to nature. This means being surrounded by critters and furry creatures, some of whom will occasionally invade your home. Twice yearly service calls and regular HVAC inspections will protect you and your family from the problems they can bring. Give us a call today!

The “H” in HVAC Is for Halloween – A Great Reminder Winter Is Not Far Off

This entry was posted in HVAC Maintenance on by .


The signs of autumn are everywhere. Pumpkins for carving, fall decorations and Halloween costumes are on display in stores. Children are choosing their favorite scary characters in preparation for the big night of trick or treating. And you are correct, the “H” in HVAC is not for Halloween – it’s for heating. However, Halloween serves as a great yearly reminder that the extreme 100+ degree temperatures of summer will soon be replaced by the cooler nights of fall. That means winter is not far off.

October is the perfect month to schedule an appointment to have your furnace inspected. The “H” in your HVAC system has been idle for months. After avoiding the extreme Arizona heat for six months, many Phoenix area residents forget winter nights in the desert can get very chilly.

Your Furnace Has Been on Summer Vacation

HVAC systems are complex, and your AC has been getting heavy use throughout the summer. Switching to heat means engaging a separate component that has not been used for a long time. Here are a few reasons why October is the perfect month for a fall HVAC checkup:

  • The Heat Is On – The first time you turn on your furnace each year can bring an unwelcome smell of burning dust. A fine layer of desert dirt and grime from summer wind storms can cover your heating elements and cause problems. During a fall service call, our technicians will inspect your furnace and remove any dust or debris from inside your heater. Also, it’s not uncommon for us to find evidence of furry friends making a home for themselves in your furnace. Air filters, which are also dust magnets, will be replaced. Remember, whenever you notice a burning smell, it’s always a good idea to have it checked out.
  • Gas Furnaces – Gas furnaces are generally very reliable. With their igniters and gas burners, they are slightly more complex than electric heaters. Unfortunately, with months of sitting idle, they don’t always fire up perfectly the first time. There is nothing more annoying than trying to figure out the instructions for lighting the pilot with a flashlight in your hand on the first cold night. To ensure a safe, first time start up for your gas furnace, have it checked in advance.
  • Have You Checked Your Thermostat Lately? – One of the most unsung and underappreciated elements of any HVAC system is the thermostat. Because they tend to work reliably and trouble free for years and years, we often inspect thermostats that are decades old. Replacing your old thermostat with a new smart thermostat can save money and make it easier to program your settings. Our service techs can explain the many options available. However, if your happy with your current thermostat, we’re happy to check it out and make sure it’s working properly.
  • Thinking Ahead to the Holidays – If you schedule a fall HVAC checkup for October or November, you can put your mind at ease knowing you’re set the holidays ahead. Now is truly the best time to get prepared for winter.

Happy Halloween

Each year, October 31st marks the start of the holiday season. We wish you and your children a safe and happy Halloween. For service so good that it’s scary call Cool Blew today for your fall tune-up.

Electricity and Your Air Conditioner – The Shocking Truth

This entry was posted in Electrical on by .


The U.S Census Bureau reported that Phoenix recently surpassed Philadelphia as the fifth largest city in the United States. 50 years ago, the number of residents in the Valley of the Sun hovered around 500,000. The current population of Phoenix is 1.6 million. This astonishing growth can be attributed to many factors. Perfect winter weather, a general migration in the U.S. from the colder Northeast to the warmer climates of the Southwest, the abundance and availability of affordable electric power and, of course, two very important words: air conditioning. Reasonably priced home air conditioning systems popularized in the 60’s and 70’s made it possible for Arizona’s exponential population growth. Air conditioning made the population grow. But, it’s electricity that makes your air conditioner go.

Facts About Air Conditioning and Electricity

It takes a fair amount of electricity to power the air conditioning system that cools your Arizona home. In fact, your AC unit uses more electricity than any other appliance (approximately 3000 to 5000 watts of power for every hour of use). This translates into extremely high energy bills during the summer months. Two-thirds of all homes in the US have air conditioning. However, in Phoenix it’s over 90 percent. Nationally, over 11 billion dollars per year is spent on electrical power for air conditioning.

Air Conditioning Breaker Switch

In the summer, when your AC unit is running constantly for weeks at a time, it is not uncommon for the breaker switch to be tripped – sometimes for no apparent reason. Possible explanations for your breaker switch to go off might be power dips or surges on the power grid or electrical issues due to lightening from storms. When your air conditioner mysteriously stops working, always check the breaker switch first. If your breaker switch is constantly going off, that might be an indication of a more serious electrical problem. You may have an undersized breaker, a faulty breaker switch or a loose breaker, which might need to be replaced.

Common Electrical Problems with Your Air Conditioner

Air conditioners are loaded with electrical circuits, wires and parts as well as fans and compressor motors. Over time, these components are subject to wearing down and may be degraded by heat, sunlight, extreme weather, gnawing critters, etc. You may be tempted (after reading a book or watching a YouTube video) to work on your own electrical issues. However, if you’re not an electrician or an AC technician, it’s best not to mess with wires, connectors and electrical problems in general. The advice we give our customers is to stick to changing the air filters and resetting the breaker switch. Electrical issues can cause serious damage to your air conditioning unit and more importantly, to you. Please be safe and call us immediately when you notice electrical issues.

What’s a Capacitor?

Capacitors are quite common, critical parts, central to all electrical motors, including the ones in your air conditioner. Capacitors regulate the start energy for the electric motors. Capacitors come in many shapes and sizes. Used mainly to store and release electric charges (similar to a short-term battery) capacitors regulate the motors in the compressor, blower and fan. If you have a faulty capacitor, you may notice a clicking sound upon start up or a loud hum if the motor can’t get going. Both sounds mean you should call for service immediately.

Leave Electrical Problems to the Professionals

When it comes to electricity and your air conditioner, the shocking truth is many people are injured each year in home repair related electrical accidents. Please remember electrical accidents can cause serious damage to you, to your air conditioning unit and to your home. When you have electrical issues, call the professionals at Cool Blew.
