If It Looks Like A Duct, Acts Like A Duct and Leaks Like A Duct – It Might Be A Leaky Duct

This entry was posted in Maintenance on by .

Modern air conditioning is a clever invention that combines technology, electric motors, fans, compressors, coils, refrigerant and more to produce cold air on demand. In addition to that, as you know from paying your monthly utility bill, a lot of electricity is used to power your AC unit. All this effort and energy goes into creating cold air which is then dispersed by the blower throughout your home through your ductwork system. Unsung and unseen, your ducts are the final piece of the puzzle that delivers precious cold air which keeps you comfortable all summer long.

How Much Cold Air Are You Losing Through Leaky Ducts?

Ducts are not only the most overlooked components in your HVAC system but quite possibly the biggest offenders when it comes to lowering the overall efficiency of your air conditioning system. Did you know that faulty ductwork can allow 20, 30 or even 40 percent of your valuable cold air to escape through leaks and openings? In our many years providing AC service in Phoenix, we have seen all kinds of unfortunate duct-tales. Here are the most common duct related problems which are all very fixable:

  • Expansion and Contraction – Ductwork, especially in an attic is subject to extreme heat in the summertime. The temperature on your roof can exceed 140 degrees. Over time, your ducts expand in the intense heat and contract with the cold air. This punishing process of constant expansion and contraction can loosen joints, connectors and seals and cause leaks.
  • Foundation and Settling – As gravity works its magic on your house and the foundation settles, parts of your home may move slightly or get out of alignment. Foundation issues are very common in Arizona homes. Crossover areas where ducts connect from one part of the house to another are particularly susceptible to getting off kilter which can cause leaks.
  • Problems with Original Installation – Depending on the contractor who did the original HVAC installation when your house was built, you may have problems that have never been detected. It pains us to perform a duct system inspection only to find out work was left undone or unfinished years ago and the homeowner has been paying the price ever since.
  • Remodeling and Clumsy Repairs – We’ve seen a lot of damage done to ductwork (especially ceiling ducts) during remodeling projects by clumsy repairmen who weren’t paying attention to what they were doing or where they were stepping. Knocking a duct out of alignment to get at something else is unfortunately a very common occurrence.

The Good News Is Fixing Your Ducts Produces Immediate Results

Inspecting your ductwork, sealing leaks and closing holes in your duct system will pay significant dividends in terms of delivering more cold air where it belongs – in your home. There’s been a tremendous amount of construction over the last 50 years in Phoenix. Many homes that were built decades ago have never had their ducts checked. It’s something most homeowners simply haven’t considered having done.

Leaky Ducts Are Costing You Bucks!

An Arizona home air conditioning system represents a sizeable investment on your part. The actual cost of electricity can amount to 60 percent of your monthly utility bill in the summer. It’s a shame to allow your cold air to vanish into thin air due to leaky ducts. Give us a call so we can schedule a duct inspection today.

How Regular Service Extends the Working Life of Your Air Conditioner

This entry was posted in Maintenance on by .

In the Valley of the Sun, air conditioners put in a lot of overtime. For many months out of the year, Arizona AC systems operate almost nonstop, providing homeowners with cool relief from the intense heat. In fact, it’s affordable air conditioning that makes it possible for people to live and thrive in the desert and is a fundamental reason for Phoenix’s phenomenal growth over the last 40 years. In 1980, the population was just under 800,000 people. Today, Phoenix is the fifth most populous city in the U.S. with 1.6 million residents, and they nearly all have air conditioners.

Replacing an air conditioning system is a major expense for homeowners. In fact, other than adding an addition or doing a major remodeling job, it’s one of the largest expenses a homeowner will incur. In the desert, it’s not a question of if, but rather when you will need to replace your AC system. Getting the most out of your AC system, both in terms of performance and longevity, is truly important. The secret to extending the life of your air conditioner is expert, regular maintenance performed by a top AC service provider. We recommend two service checkups per year – one in spring and another in fall. Here are a few service keys to keep your air conditioner running smoothly for years to come:

  • Keep Your Air Conditioner Clean – The desert can be a windy, dusty place and dust is the enemy of your air conditioner. Regular cleaning, removing dust and dirt and lubricating moving parts is essential. Even though you may not notice it, wind-blown dust is a problem for your AC system.
  • Replace Air Filters – Replacing air filters on a regular basis helps eliminate dirt and dust from getting into your air conditioning system. Performing this simple task six times per year will lengthen the life of your air conditioner and improve the indoor air quality of your home.
  • Check Electrical Components – Over 80 percent of all air conditioning repairs are related to electrical issues. Extreme desert conditions (wind, dust, high temperatures, exposure to UV rays) are hard on electrical motors, parts and wiring. Many AC units are located on the roof, which means in the summer months, your air conditioner is toiling in temperatures above 140 degrees. Electrical issues can be dangerous and are best handled by professionals with proper equipment.
  • Check Refrigerant – It is crucial that refrigerant is monitored regularly and that your system has no leaks. When you have too much or too little refrigerant, it makes your air conditioner work harder to achieve the desired indoor temperature. Special tools are required to check your system for leaks.

Time to Schedule a Spring Tune Up

Spring is the best time of year to schedule a system checkup. Our friendly service technicians will be happy to perform a full inspection and provide you with an assessment of your air conditioner. Don’t head into summer unprepared. Why not call us today?

How to Avoid A Costly Air Conditioning Compressor Breakdown

This entry was posted in Maintenance on by .

If you ask a random group of five phoenix air conditioning repair technicians, “What’s the most important part of an air conditioning system?” It’s quite possible you’ll get five different answers. There are so many critical components working together to deliver cool air through your home’s AC system, it’s almost impossible to label a single part as the most critical. However, if you ask those same service specialists, “What’s the most expensive repair on a home AC system?” They’ll all give you the same answer – replacing a faulty air conditioning compressor.

Summer Will Be Here Soon

Phoenix is known as the hottest city in America and with good reason. The summers are long, and the desert sun is unrelenting. There are more 100+ degree days in Phoenix than just about any other major metropolitan area in the U.S. All that heat for much of the year puts a tremendous strain on your air conditioning system.

What Does an Air Conditioning Compressor Do and What Causes It to Breakdown?

Your air conditioning compressor is one of the largest components in your HVAC system and is installed either on the ground outside your home or up on the roof. At the very center of the cooling cycle, the compressor (you guessed it) compresses and pumps refrigerant through highly pressurized pipes throughout your entire system, to achieve cooling inside and to transfer (remove) unwanted heat outside. There are many factors that can cause your compressor to break down, including:

  • Clogged or Dirty Coils – The coils in your compressor facilitate the transfer of heat out of your house into the outside air. Unfortunately, coils are a magnet for dirt, debris and grime. If your coils become covered with dirt, it inhibits proper functioning and your compressor ends up working harder to achieve the same level of cooling. Over time, clogged coils will damage your compressor.
  • Leaks or Punctures in the Coils – If you have ever heard a slight hissing sound coming from your compressor, it could be refrigerant escaping from a tiny leak. Small holes and punctures occur, often due to corrosion. Depending on the age of your air conditioner, corrosion may be affecting the refrigerant level in your compressor.
  • Improper Refrigerant Levels – Your pressurized refrigerant lines are a closed system and require an exact amount of gas to run properly. Too much or too little refrigerant will cause problems within your system. Our trained service technicians will check for correct refrigerant levels in your compressor and system during a spring tune up.
  • Electrical Power Issues/Normal Wear and Tear – Electrical power and the correct voltage (not over, not under) is crucial to the normal operation of your compressor. Over time, depending on how old your AC system is, wires can degrade, and other electrical issues may arise simply due to normal wear and tear. Power surges, not uncommon during the summer in Phoenix, can cause electrical issues with your AC system.

Is a Noisy Air Conditioner Ruining the Peace and Quiet of Your Home?

According to the National Weather Service, the summer of 2018 featured no less than 128 days of 100 degrees or more. That’s over four months of serious Arizona heat! The long-range forecast in 2019 is for more record-setting triple digit temperatures. As modern inventions go, it’s hard to imagine a more useful, life-saving appliance in your home. Air conditioners make summer in Arizona livable. However, for all their ingenious heat transferring qualities, air conditioners are not always the quietest appliance in your home.

What Is That Noise?

Do you experience an ear-splitting high-pitched whine every time your air conditioner starts up? Are there serious thumps and ka-chunks when the compressor kicks in? This might be your air conditioner’s way of telling you, “I’m not going to be ignored. It’s time for my spring AC service call.”

Here’s a list of common AC noises and what they might be indicating as far as your air conditioner is concerned:

That Annoying, High-Pitched Squeal

A high-pitched whine or squeal is a sound often associated with slipping belts or an issue with the bearings. Either way the noise is most unpleasant and indicates service is needed.

Thump, Ka-chunk or Loud Rattling During Start-up

There is some argument as to whether the sound is more of a Ka-chunk or a thump. We’ll let the sound effects experts debate that point. Unfortunately, these noises are frequently caused by loose mounts, but more often than not, can indicate a problem with the compressor. This is not a sound you want to ignore.

Tick-tick or Clicking Sounds

A rhythmic tick-tick or clicking sound is often caused by faulty fan blades. Sometimes, it can be as simple as a branch or a twig lodged in the fan. An obvious question is, “How can something hit the fan blade when it’s in an enclosed area?” Occasionally, high winds from thunderstorms blow branches and debris into your air conditioner. Clicking sounds can also be caused by defective relay switches.

A Loud Buzz

Air conditioners rely on electric motors to make the fans go, power the compressor, move liquids through the pumps and more. As with any electrical device or motor, if you hear a loud buzz or notice an incessant humming coming from your air conditioning unit, you’ll want to turn it off right away. If you hear crackling or detect a burning smell, you’ll want to act immediately. Turn off the AC unit at the circuit breaker and call for service. Electrical problems are responsible for over 80 percent of AC issues.

Wind Whistling Sound Near Vents Inside the House

If you hear wind whistling, whooshing or the faint sound of a distant train coming from your vents, you can rest assured, it is not an errant Amtrak whistle or a ghost train calling to you from the other side, but rather a pretty decent hint that there’s a loss of pressure or an opening somewhere in your duct work.

The Only Sounds You Want to Hear – The Sounds of Silence

“And the people bowed and prayed, to the “freon” God they made…” so wrote Paul Simon in his famous 60’s hit, The Sounds of Silence. When your air conditioner is working properly, you’ll hear a little whoosh from the fans or no noise at all. Silence is the sound of a healthy air conditioner. For most people, out of sight – and out of earshot – is most ideal. Give us a call and we’ll be happy to help your air conditioner pass the ear test. Call us today.

Spring Arrives Early in Arizona – Will Your Air Conditioner Be Ready?

This entry was posted in Maintenance on by .


One of the great benefits of living in Arizona is taking advantage of the spectacular winter weather and the early arrival of spring. In February, while most of the country finds itself knee deep in winter, Phoenix residents attend spring training games in shirt sleeves and shorts. In 1946, Bill Veeck purchased the Cleveland Indians and brought them to Arizona for pre-season exhibition games. Soon after, Major League Baseball established the Cactus League, which has grown tremendously since it was founded. Last year, Cactus League games attracted 1.75 million fans and visitors from all over the world. Spring training gives pitchers and position players the opportunity to tune-up and get ready for the long season ahead. The question for your household is, with spring just around the corner, will your air conditioner be ready for the rising temperatures and the summer season of 2019?

Spring Training for Your Air Conditioner

There’s no question, your air conditioner is the workhorse of all your major household appliances. Once the hot weather kicks in, your AC unit generally runs many hours per day from early spring until late fall. Often installed on the roof, HVAC units are subjected to extreme temperatures, UV rays, high winds, dust storms, monsoon rains and other extreme desert conditions. A highly complex system loaded with fans, motors, moving parts and intricate electrical components, your air conditioner, in order to run flawlessly, requires regular service and fine tuning, just like an automobile. `

The key to trouble-free, continuous cool comfort in your home from spring training through the World Series finale, starts with an AC inspection and spring tuning well before the summer heat turns up. Here are a few of the most common issues we find after air conditioners have been sitting idle through the winter months:

  • Dirty Air Filters and Clogged Coils – After running for a full season and being idle for months, your air conditioner often suffers from dirty air filters and clogged coils. Our service technicians will install new air filters and remove the desert dust and debris from your coils and your entire unit. We will check for leaves, branches and debris blown into your air conditioner during storms, and we’ll make sure you have no animal infestations.
  • Electrical Issues – Did you know that over 80% of air conditioning break downs are related to electrical issues. From capacitors to condensers, electrical motors, fans and wiring, your AC unit has many sophisticated component parts that need to be checked regularly to make sure they are working properly. It’s important to note, many electrical parts simply wear out over time from all the heavy use under the unrelenting Arizona sun.
  • Replacing Freon and Checking for Leaks – A spring tune-up will include checking for leaks and replacing Freon as needed in your air conditioner. If it has been more than a year since your last inspection, remember the constant vibration of your AC unit can dislodge or otherwise degrade connections and couplings in your air conditioner. Leaking Freon can be damaging to your AC unit and harmful to the environment.

Why Not Have Your Spring Tune-up Done Before You Turn on Your Air Conditioner?

This year, don’t wait for something to go wrong before you call for service. Managing your home environment and personal comfort means planning ahead. We recommend one service call in early spring and another in the fall. This enables our friendly service technicians to monitor your HVAC system on a yearly basis to uncover and fix small problems before they turn in to big ones. Give us a call today!
