Monday, March 4th, 2024A Cracked Heat Exchanger Is a Major Furnace Repair Issue
Monday, February 19th, 2024Gas furnaces are reliable and powerful heating systems that can work for many years delivering warmth to a home. It’s why they’re still the most common household heating system across the country.

But as long as a furnace receives regular maintenance each year and prompt repairs when needed, the risk is minimal.
We want to focus on one specific furnace repair problem that can create serious health hazards: a cracked heat exchanger. The more you know about it, the easier it will be to prevent it.

What Exactly Is “Puron” and How Is It Different From Other Refrigerants?
Monday, January 22nd, 2024If you don’t have deep knowledge of the refrigerants used for air conditioning systems and heat pumps, that’s fine. This is a technical field and you want to leave any work with refrigerants to certified HVAC professionals. For example, you might think that the refrigerant in your current AC is called “freon.” But freon isn’t a general term. It’s a brand name for a specific type of refrigerant.

Why Pilots Lights Have Gone “Out of Fashion”
Monday, November 27th, 2023Once upon a time, when people discussed gas furnaces, they often talked about the pilot light. This flame burned through the winter in the furnace, ready to ignite the burners as soon as gas started to flow to them. Sometimes the pilot light would go out and need relighting—and this was often Troubleshooting Step #1 on lists of what to do if a gas furnace stopped working.
But now the question people are asking isn’t “how to light a gas furnace in Fresno, CA” so much as wondering what happened to the pilot light. Some models may still use them, but not many. The pilot light has gone out of fashion, and for some good reasons.

Sealed Combustion Furnace: What Makes It Different From a Standard Furnace?
Monday, October 16th, 2023How much do you know about the operation of your furnace? You may understand the basics of how a gas furnace runs: gas burners ignite, hot combustion gas collects inside the heat exchanger, the heat from the exchanger walls transfers to the air, and a blower pushes the air into the ventilation system. But there are some differences between furnace construction that can make a significant difference, such as whether your furnace is a sealed combustion furnace.
If you’ve never heard of the term sealed combustion furnace, we’re glad to explain to you what it is and why it’s different—and often superior—to a standard furnace. If you’re interested in sealed combustion heaters in Fresno as a choice for your home, we can assist you.
Is Electronic Ignition Only for Electric Furnaces?
Monday, September 18th, 2023You may have heard about furnaces switching to something called electronic ignition. If you have a gas furnace, you might think this doesn’t apply to you—after all, wouldn’t electronic ignition only apply to electric furnaces?
The keyword you might be overlooking is ignition, which means igniting something. Electronic furnaces do not use any type of combustion or burning to work. Instead, they allow electric voltage to flow through a series of heating elements, which then warm up through electrical resistance. The only furnaces that use electronic ignition are the ones that burn natural gas (or less common options like propane or oil).
If you’re curious about how this works and how to light a gas furnace with electronic ignition, we’ll explain below. We’ll also look at why electronic ignition is a beneficial change from standing pilot lights.
