When an AC Runs for Too Long

Monday, May 1st, 2023

We’ve written before about the problem of a short-cycling air conditioner, which is when an AC stops its cooling cycle (which usually lasts 15–20 minutes) earlier than normal, then continues to turn on and off rapidly. This is a serious problem that often requires calling for repairs.

There is the opposite version of this problem—an air conditioner that runs for far too long. When an air conditioner spends more than 30 minutes on its cooling cycle, or won’t stop cooling at all, it’s a huge waste of energy and will make the house too cold.

There are several reasons you may start to see this “nonstop AC” problem in your home. You can count on our technicians to find out the exact problem and have it fixed.

The Benefits of Ductless Mini Split Systems

Monday, July 11th, 2022

Ductless mini split systems are a type of comfort system for homes that work through a series of wall-mounted air handlers. Think of one of these systems as similar to a standard split system air conditioner, except the condenser doesn’t connect to a single indoor blower and evaporator hooked to ductwork. Instead, it connects to a series of separate mini-air handlers/evaporators placed throughout the rooms.

We offer installation of ductless heating and ductless air conditioning Fresno, CA. These systems aren’t ideal for all homes, but their benefits make them attractive options if you’re planning on making upgrades or changes to your HVAC system or if you live in an older home lacking ductwork. 

Here are a few of the best benefits of ductless mini splits…

Why Does My AC Smell Strange?

Monday, April 18th, 2022

An air conditioning system is not supposed to have any noticeable odor as it runs. The air from the vents should have the neutral smell of the rest of the house. If you start to detect any smell from the air vents you’ve never noticed before, such as a dirty laundry stink, rotten eggs, or an acrid burning, it’s something to pay attention to.

You may need to call our technicians for air conditioning system repair in Fresno, CA after you notice any of these odors. A few may have simple causes, but in many situations, these odors warn of a bigger problem with an AC. We’ll look into these strange air conditioning system smells and what they may mean.

We’re experiencing extremely hot days in the Central Valley—days with true summer heat, and spring has only just started. You may have had to turn on your AC for the first time in several months to battle the heat. But your air conditioning system is going to need extra help to handle the continuing heat we’ll face through the middle of the year: professional air conditioning maintenance.

We always stress with our customers the importance of having their air conditioning systems professionally inspected and tuned up annually, preferably in spring to beat out the hot weather. The weather is already turning hot, so the time to call us to schedule your regular air conditioning maintenance in Fresno, CA is now.

Getting a Bigger AC Is Probably Not a Good Idea

Monday, October 4th, 2021

We’re accustomed to thinking that getting an appliance that’s “more powerful” is always for the best. But this isn’t the case—and it’s certainly not the best when it comes to a central air conditioning system.

Maybe you’re unhappy with your current air conditioning in Fresno, CA. This recent summer was hot, and when you lowered the thermostat to your standard comfort level, you didn’t feel as cool as you expected. The air conditioner just didn’t seem like it could handle the heat. Getting a bigger AC might sound like a good solution; it seems sensible. But it rarely is. We’ll talk more about air conditioner size below and how to get the right cooling.

How Has Your AC Held Up This Summer?

Monday, September 6th, 2021

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.

Late August Still Isn’t Too Late for an AC Tune-Up

Monday, August 23rd, 2021

It’s hot outside in August, and it’ll be hot in September as well. Summer isn’t finished, and your home’s air conditioning system has hard work ahead of it.

And that’s one of the reasons it’s not too late to have your annual AC tune-up and inspection. We recommend our customers have this maintenance service done in spring because it gets the air conditioning system ready before the first of the big heat waves arrive, and it takes the most advantage of maintenance’s benefits. But, and this is the key point to remember, AC maintenance does not have an expiration date. It only needs to be done each year.

So, although we recommend having your future AC tune-ups done in spring if possible, it’s not too late to have the work done now. It’s far better than skipping it for a year.

5 Reasons an AC May Start Short-Cycling

Monday, August 9th, 2021
air-conditioning-system-grill-top-down

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.
