Your AC in a Heat Wave: A Few Things to Know

Monday, September 17th, 2018

sunshine-imageThe heat here in the Central Valley these last few weeks has been … well, there’s been a lot of it. Recording breaking heat. In July, Fresno broke the record of consecutive days with triple digit heat—22 days, starting on July 6, according to the Fresno Bee. The newspaper also predicted the heat might subside in late August. But the heat waves sweeps on and on. We’re still experiencing days peaking in the triple-digits, with other days hovering in the 90s.

We hope you haven’t had to deal with any serious heat-related emergencies (we did a post on recognizing these emergencies) and that your air conditioner is still managing to keep your home cool. In fact, let’s talk about your AC and the heat. There are a few important things to know about running your air conditioner during these extremes.

How Leaking Refrigerant Affects an Air Conditioning System

Friday, July 6th, 2018

air-conditioner-unit-being-repairedOne of the more common problems that affects residential air conditioning systems is refrigerant leaks. An AC is designed to work with a specific amount of refrigerant, known as the system’s charge. The AC doesn’t use up the refrigerant as it runs, so under ideal circumstances, the refrigerant will remain at the same charge for the life of the system.

But circumstances are rarely ideal. Leaks can occur along refrigerant lines because of corrosion, and this will allow the refrigerant to escape. When the charge of an air conditioner drops, it will have negative effects on the AC, eventually leading to a complete breakdown. Below are the main ways refrigerant loss affects an air conditioning system.

Duct Sealing Can Improve Your Air Conditioning

Thursday, June 7th, 2018

duct-sealing-with-caulkingDuring a hot summer here in the Central Valley, you’ll want your air conditioning system to work at its best. This means reliable, even cooling around the rooms, and utility bills that don’t rise too high. Standard malfunctions can threaten your AC’s performance, but they aren’t the only danger to the well-working of your air conditioning system. Many people don’t realize that poor ductwork is often a serious problem for cooling systems.

However, there is a solution to this. Even if you don’t think your air conditioning system is performing badly, it may benefit from this same trick. And that trick is—duct sealing.

What to Do if Your Air Conditioning System Is Leaking Refrigerant

Monday, August 28th, 2017

air-conditioner-units-near-grassRefrigerant loss is one of the major problems an air conditioning system may encounter during its service life. And it’s not only a problem that occurs in aging, over-the-hill ACs. An air conditioning system that’s been in service for around 5 to 6 years can develop corrosion along its refrigerant lines because of exposure to formaldehyde in the air. It’s wise to always watch for indications that your AC, no matter how old it is, may be losing refrigerant to leaks:

  • A decline in cooling capacity
  • Hissing sounds from the cabinets
  • Ice developing along the indoor evaporator coil
  • Short-cycling (i.e. the compressor turns on and off repeatedly over a short time)
  • Hard starting
  • Liquid dripping from the indoor cabinet

These symptoms can point to other problems, but no matter the cause, they need professionals to look into them to see what air conditioning repairs will remedy the problem.

My AC Is Tripping the Circuit Breaker! What’s Wrong?

Tuesday, June 20th, 2017

During the winter, we looked at how a tripped circuit breaker can occur with a furnace. It can happen with your air conditioning system as well—it definitely has to work hard during our hot summers here in the Central Valley! An air conditioning system is a powerful appliance that draws on large amounts of electricity, which makes it possible for it to demand too much and cause a breaker to trip to protect the circuit. When that happens, the air conditioning system won’t run.

We advise people to always check their breakers when their AC suddenly shuts down. If you run into this situation, but the air conditioner continues to cause the circuit to trip, you have a more serious issue that will require professional air conditioning repair in Oakhurst, CA or elsewhere in the Central Valley.

Some Specific Consequences for an AC without Maintenance

Tuesday, May 23rd, 2017

tools-on-ac-unitWe place a special emphasis on regular air conditioning maintenance during the spring. There’s no better way to protect your investment in your HVAC equipment and ensure a long service life. Maintenance also helps keep your air conditioning system running at high efficiency and with reduced chances of breaking down suddenly during a hot day.

We’d like to explain in more detail exactly ­why maintenance is so essential. To do that, we’re going to list some of the ways that lack of maintenance creates trouble for an air conditioner. Explaining to people that “wear and tear” is bad news for an AC only tells part of the story. Actually showing people what this wear and tear is and what it does gets to the heart of the necessity of annual air conditioning system maintenance.

We can still expect a few more weeks of warm-to-hot weather in the Central Valley before the fall cooling starts. This means you must keep an eye on your air conditioning system to watch for any late-season repair issues. You shouldn’t shut off your AC for the season if it has a malfunction, since this can lead to larger problems with the system when the warm weather returns.

Air Conditioning Question: What Does Refrigerant Do?

Monday, May 4th, 2015

Modern air conditioning systems are complicated machines that require a balance of components working in peak condition: the compressor, fans, coils, capacitors, motors, etc. All of these parts play vital roles in providing a home with cool temperatures. If one of the parts starts to fail, it can mean a drastic drop in efficiency and effectiveness.
