September 16th, 2024

If you’ve heard anything about duct cleaning, you might wonder if it’s really an important service. The simple answer is: if your home has ductwork, it will need regular duct cleaning. Not necessarily every year, but you will have to get into a regular schedule to have a professional HVAC service come to your home for duct cleaning in Fresno, CA.

We have to emphasize professional. People may think they can do duct cleaning on their own with a long-hose vacuum. Or they may turn to a salesman who offers a suspiciously low quote for duct cleaning but doesn’t have any real credentials. Say “no” to both the salesman and to yourself! This job absolutely needs professionals for it to provide any benefits.

What It Means When Your AC Runs for Too Long

September 2nd, 2024
cold-man-and-woman-in-parkas

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.

Whole-House Generators: Why Choose One Over a Portable Generator

August 19th, 2024

When it comes to generators for a house, you have a choice between several types of models. Portable generators are a popular choice because they’re less expensive to purchase than having a whole-house generator installation in Fresno. However, we don’t recommend going with a portable generator if you’re looking to get your home through an extended power outage. Portable generators have their uses, but when it comes to protecting your home and family, having our professionals install a whole-house generator is your best option. We’ll explain more below.

Why Your Water Heater Needs Its Anode Rod Regularly Changed

August 5th, 2024

Can water heaters rust? Most definitely! We’ve looked at how this can occur before and what it means for a water heater. Thes short version is that it usually means a water heater must be replaced. An extremely old water heater can begin to corrode, which is as good a sign as any that the unit is overdue for retirement. But younger water heaters can rust as well if they aren’t cared for properly.

This brings us to our topic today: the anode rod in a storage tank water heater, also known as the sacrificial anode rod for reasons that we’ll explain. One of the most important maintenance tasks to keep a tank water heater running for many years is to make regular anode rod changes—because the anode rod is one of the most important defenses a water heater has against rust and other types of corrosion. Follow us below as we look into the anode more.

What Causes Poor Indoor Air Quality in Homes?

July 22nd, 2024

According to the US Environmental Protection Agency, the air quality inside homes and other buildings is often three to five times worse than the air outdoors. This goes against what most people think of pollution, but it’s true. And low indoor air quality is a serious problem. The EPA lists various short-term and long-term negative effects of indoor air quality, including:

  • Short term: irritation of the eyes, nose, and throat, headaches, dizziness, fatigue
  • Long-term: respiratory diseases, heart disease, cancer

We offer indoor air quality services, such as air filters, for our customers to help them enjoy better health and greater comfort in their homes. In this post, we’ll explain exactly why people need this help: the causes and the sources of low indoor air quality (IAQ).

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

July 8th, 2024
circuit-breaker-panel-close-up

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?

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?
