Did you remember to have AC maintenance in Fresno, CA in the spring? If you did, then you gave your air conditioning system the best beginning to the summer. (If you didn’t … it’s not too late to schedule it!) But as wonderful as maintenance is, it can’t prevent all air conditioning problems or stop an AC from eventually wearing down.

As we move toward the fall, we recommend you think about your air conditioner’s performance over this last summer, especially if the system is more than 10 years old. If your air conditioning system is showing signs it needs repairs or it’s ready for retirement, have the service done as soon as possible. (Fall is a good time to replace older air conditioners because HVAC technicians have more open schedules.)

Let’s go through a few basic air conditioning considerations to see how well your cooling system held up.

5 Reasons an AC May Start Short-Cycling

Monday, August 9th, 2021

An air conditioning system runs in cycles where the compressor turns on to provide cooling for the house, then shuts down until the thermostat registers it needs to turn back on. These cooling cycles should last at least fifteen minutes.

If you notice your AC shuts down after only a short time, then turns on again soon after, it’s short-cycling. This malfunction makes it hard for the air conditioner to fully cool a house. It also wastes energy (compressor start-up draws on large amounts of electricity) and wears down the AC components rapidly. Below we’ve listed five frequent causes of this problem.

What Causes Ice to Form on an AC’s Evaporator Coil?

Monday, July 26th, 2021

A mistake that homeowners often make about the way their air conditioning systems work is to assume that ice appearing along the indoor evaporator coil is normal, just a sign the AC is working extremely well at cooling down the air.

The truth is that ice should never appear on any part of an air conditioner. When ice appears along the evaporator coil, it means something is interfering with the standard way the air conditioner operates. The ice creates a major problem on its own, but the source of the ice forming may be an even worse problem.

Why Your AC Is Running Continuously

An air conditioning system that won’t turn on is obviously a major problem. But an air conditioning system that continues to run and run without cycling down is almost as big a problem. A nonstop air conditioner will waste massive amounts of energy, make parts of the house too cold, and wear down the unit rapidly so it needs multiple repairs and an early replacement.

What has turned your AC system into a runaway train? We’ll examine several potential causes below. You shouldn’t attempt to diagnose the problem on your own, however. You’ll need an expert HVAC contractor in Fresno, CA to figure out what’s wrong and how best to fix it.

Why Is My AC Not Blowing Out Any Air?

Thursday, August 20th, 2020

Spinning-fan-closeupThere are different ways an air conditioning system can stop working. Sometimes the blower will turn on and send air to the room vents, but that air won’t be cool. Or the AC could keep shutting off after only running for a few minutes. But the most alarming problem for a homeowner—because it’s so immediately clear there’s trouble—is when the AC won’t blow out any air at all. Nothing comes out of the room vents, hot, cold, or otherwise.

What’s behind the “no blow air conditioner”? It could be a variety of malfunctions or errors. We’ll look into some possibilities below to help you understand when to call us for air conditioning repair in Fresno, CA or elsewhere in the Central Valley.

Why Does an Air Conditioner Short-Cycle?

Monday, June 15th, 2020

compressor-in-ac-unitOne of the most common signs of something wrong with a central air conditioning system is short-cycling. This is when an air conditioner fails to complete a full cooling cycle and instead shuts down early, only to turn back on again a short time later. Short-cycling is bad news for a few reasons:

  • It wastes power, resulting in higher utility bills
  • It puts extra strain on the AC, leading to an early replacement
  • It doesn’t give the system enough time to spread cool air evenly around the house

Under normal circumstances, you can expect your home’s air conditioning system to run for 15 minutes or more before it cycles down. If you notice that it’s running for shorter times than this and you hear it turn on multiple times in an hour, you should look into it. Sometimes short-cycling is a simple issue to correct. But in many cases, you’ll need to call technicians to diagnose what’s happening and then handle the necessary air conditioning repair in Fresno, CA.

Monday, July 15th, 2019

stripped-electrical-wireWhenever an air conditioning system abruptly shuts down—the fan won’t come on, the compressor won’t come on—one of the first things we recommend homeowners check is their electrical panel. A tripped circuit breaker might have caused the air conditioning system to lose power. Resetting the breaker may solve the problem.
