How 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.

One of the trickiest parts of navigating a new heating system installation for a house is figuring out energy efficiency ratings and what they mean.

This question is one we can start to answer by first asking another question:
When you move into a new home, usually the AC and the furnace were installed at the same time—and usually they’ll need to be replaced at the same time as well. In other cases, either the AC or furnace will run down before the other (air conditioning systems in general don’t last as long as either gas or electric furnaces), and you’ll arrange to have the older unit replaced.
Spring is a great time of the year to make significant changes to a home’s HVAC system. Between the extreme cold of winter and the extreme heat of summer is a mild period when a house won’t need either its heating system or AC running, and HVAC technicians have more open schedules for convenient appointments.
