What It Means When Your AC Runs for Too Long

Monday, September 2nd, 2024

You get used to the way that your AC turns on and off—what’s known as its cooling cycle. An air conditioner cycles on when the thermostat sends a request for cooling, first turning on the blower fan and then the compressor. Once the thermostat registers the cooling has reached the target temperature, it signals the AC to cycle down, shutting off the blower fan and the compressor.

If you notice that your air conditioner is staying on for much longer, rarely cycling down, something is wrong. You may need to contact us for AC repair to resolve an issue in the HVAC system. You don’t want the air conditioner to continue to run, wasting power and making your home too cold. 

Below, we’ll look into what might cause this “runaway” AC trouble.

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

Monday, July 8th, 2024

The electrical panel in your home, i.e. the breaker box, serves the important function of protecting your electrical system from increases in voltage that can come from electrical shorts and appliances that place too much demand on their circuits. A breaker trips to cut off the voltage flow to the strained circuit, after which you can reset the breaker.

Your air conditioner may trip its circuit breaker at some point, as it’s one of the most powerful electrical appliances in your house. (If you don’t have an electric water heater, then it is the most powerful electrical appliance.) If you have to reset the AC’s breaker at some point, that’s usually not a serious problem. However, if the AC is regularly tripping the breaker, you may need to have AC repair done because something is wrong that’s causing the air conditioner to work harder than normal.

We’ll take a look in more detail at this situation below.

The Future of AC Refrigerants: What Comes After Puron?

Monday, June 10th, 2024
question-mark-badge

As the HVAC industry continues to evolve, one of the biggest changes we’ve seen over the past few decades is the change in air conditioning refrigerants: R-22 (commonly known as Freon) was replaced by R-410A (known as Puron). This change was driven by the need to reduce the environmental impact of air conditioners, as R-22 is a hydrochlorofluorocarbon (HCFC) that depletes the ozone layer. Puron, on the other hand, is a hydrofluorocarbon (HFC) with no ozone depletion potential, making it the more environmentally friendly choice. 

However, as technology and environmental standards advance, it’s a good time to ask: What comes after Puron?
