Why You Have a “Start-Stop-Start-Stop” Air Conditioner

Monday, April 12th, 2021

You’ve been searching online to find out why your air conditioning system seems caught in a rapid start-stop loop. Of course, you expect your AC to turn on for a stretch and then turn off for a period before it turns on once again: this is the regular operation as long as your house is warm enough for the AC to need to turn on in the first place. 

But an air conditioner shouldn’t start and stop repeatedly over a short time. If you have an AC that is running for less than ten minutes, staying off for about the same time, and then coming on to repeat the cycle, you’re right to believe there is a problem.

Fortunately, you’ve found the contractor who offers the Glendale, AZ air conditioning services that can solve this problem.

Knowing when it’s time to schedule an appointment for a new air conditioning installation in Glendale, AZ is the key to making a smooth transition without enduring any roasting hot days in your house. After all, you don’t want to get caught with a failed AC during one of the hottest summer days in Phoenix— when it’s more than 110°F outside!

Understanding how many years you can expect from your current AC is an essential tool in the “fight” to ensure you always have a working cooling system. The trouble is that it’s not easy to give a straightforward, one-number-fits-all answer to the question in the title. Many factors come into play when determining how many years an AC has left in it. We’ll get into details below, but the best way to get a health-care check on your air conditioner is to schedule regular maintenance for it this spring and ask our technicians about how its future is looking.

Some Special Advantages of Scheduling AC Maintenance

Monday, March 15th, 2021
thumbs-up

We declared February to be “Air Conditioning Maintenance Month.” In a place that gets as hot as Phoenix, February is the right time to get regular air conditioning maintenance in motion. 

But if you still haven’t scheduled your AC tune-up and inspection with our team, March is a great time as well. In fact, there isn’t such a thing as an “expiration date” for air conditioning maintenance; it just needs to be done every year. Still, the sooner you have it done, the more you’ll enjoy the benefits of it through the imminent hot weather.

Why an AC Compressor May Burn Out

Monday, November 23rd, 2020

Your air conditioning system worked hard this summer, and it’s probably still putting in work because the heat is carrying through the fall. Because you won’t be ready to schedule your next AC maintenance appointment until spring, it’s wise to pay special attention to how the AC is currently operating. You want to catch any problems early so you can arrange for air conditioning replacement or air conditioning repair in Tempe, AZ with our team. 

We want to talk about one of the biggest issues your AC may run into, which is a burnt-out compressor. The compressor is the literal heart of the air conditioning system, since it’s what causes refrigerant to circulate and carry out heat exchange. (Note: If you use a heat pump, all of this applies to it as well, since its compressor operates the same way.) If the compressor fails, it often means the entire air conditioner must be replaced.

Reasons for Compressor Burn Out

A compressor burns out when the motor overheats and the wiring in it fuses with the casing. The motor is part of the compressor’s housing, so a burnt-out motor means a burnt-out compressor. What can cause this burn-out?

  • Refrigerant floodback: Liquid refrigerant is not supposed to move into the compressor. If this occurs, it will cause the oil in the compressor to break down, leading to mechanical strain that will overheat and burn out the motor. Refrigerant floodback can occur if the AC is overcharged with refrigerant, which is a common problem caused by amateur repair work.
  • Low refrigerant: Refrigerant leaks are extremely detrimental to an AC, and the main reason is that the lower amount (charge) of refrigerant will cause the compressor to overheat. 
  • Electrical overload: There are several sources for excess voltage overloading the motor and causing burn out. There may be an electrical short, a voltage surge, or a drop in voltage causing the motor to make a higher demand that overwhelms it. 
  • Strain from short-cycling: We’ve talked about short-cycling before. It’s a phenomenon where the AC becomes trapped in its start-up cycle and turns on and off rapidly over a short time. The motor draws on the most electrical power at start-up, and it can much more easily overheat because of this. If you notice short-cycling, please have a technician on the problem soon to avoid compressor burn out. 
  • Mechanical issues due to degradation: In other words, the motor is plain worn-out, possibly from age. If the compressor fails in a system that is older than 10 years, it’s likely because the mechanical parts are too worn down. 
  • Corrosion: High moisture levels can sometimes lead to corrosion beginning in the motor that will cause burn out. This is avoidable with regular maintenance.

If you notice a decline in cooling in your house, an increase in humidity, hear strange noises from the outside cabinet of the AC, or detect short-cycling, please shut off the air conditioner and call our technicians. The sooner we’re on the problem, the better chance we have of heading off a burnt-out compressor and need to replace the system.

Preparing for fall in Arizona isn’t as extreme a job as it is in more northern states where the change in seasons means heading toward days where the temperatures are below freezing. But we still have to make adjustments for cooler weather, and we also have to make sure our air conditioning systems remain in top shape because they may need to kick back on at any time.

So, what HVAC service in surprise, AZ do you need to help you get ready for fall? We have some suggestions of ways that we can best serve you as we move toward the season of pumpkins and somewhat cooler weather.

Is It Important to Know the SEER Rating for a New AC?

Monday, August 17th, 2020

SEER is one of two ratings used to measure the energy efficiency of an air conditioner. (The other is EER, we’ll get to that in a minute.) Because SEER is often displayed prominently on air conditioning systems and is one of the criteria for a unit to earn the ENERGY STAR label from the Department of Energy, people imagine it’s important. But how important? Is it the main factor in choosing the air conditioner when you are ready for an AC installation Glendale, AZ?

No, it’s not—but it’s still important!

Water Dripping From Your AC? Let’s Take a Look!

Monday, August 3rd, 2020
water-droplets

What are the normal sounds you hear from your central air conditioning system when it’s running? The whirring of the motors, the movement of air through the ducts, and the occasional dripping of water.

About that last sound … do you know why you hear water in your AC? It’s not because an air conditioner uses water to cool the air. Water is a product of how the air conditioner cools the air. As the blower fan pushes warm air over the evaporator coils in the air conditioner, the cold refrigerant in the coils absorbs heat from the air and causes moisture vapor to condense along its surface. It’s like the way moisture appears on the outside of a glass of cold liquid during a hot summer day.

However, the air conditioner is set up so that water leaves your house. If you notice water is dripping from your air conditioner, that’s not a good sign. Something is wrong with the condensate drainage system the AC uses to remove the water moisture, and you may need to call us for air conditioning repair in Mesa, AZ.

Why is this happening? A few possibilities:

Condensate drain is clogged

The water moisture from the evaporator coils drips down from the A-frame of the coils and into a shallow pan. The water then moves down a drain, helped by a special pump. This drain, like any drain, can become clogged. Algal growth is a common way this happens, but small debris can also work its way into the drain. The pan (only about 1” deep) will soon overflow, tripping a safety switch to shut off the AC. You’ll need pros to clean the drain.

Broken condensate pump

A small pump is responsible for moving the water from the shallow pan and either into the wastewater system or out a PVC pipe that deposits the water outside. The pump motor may burn out, making it difficult for the pan to drain, leading to the overflow and water leaving the AC.

Loose drain

Corrosion can weaken the connection of the drain to the condensate pan, leading to the pan coming loose. This will permit water to drip straight out of the air conditioner and into your house. Usually the entire pan and drain system must be replaced by professionals.

Cracked drain pan

The condensate pan is made from plastic, and in most HVAC cabinets it is set up over the furnace. Heat from the furnace over the years can cause the pan to eventually crack and allow water to drip out. The pan must be replaced if this happens—although the AC may be so old at this point that getting a new system is a better idea. Also, you don’t want water to drip onto the furnace, since it can cause corrosion on the heat exchanger and lead to potentially dangerous heat exchanger cracks.

When in doubt about your AC, call our technicians and leave the diagnosis and repair to us. We have 24/7 emergency service available.
