Furnace Repair

Don’t get left in the cold! Is your furnace acting up, blowing cold air, or making too much noise? Our experienced team of professionals is here to keep your home warm and cozy. We repair all makes and models, and we will never try to sell you a service that you don’t need. Our technicians are honest and hard working, and we’re always transparent and fair about the work we do.

Furnace Replacement

Sometimes a repair is not sufficient to fix your furnace. Sometimes a new furnace is the most cost-effective and energy-efficient way to go. We will always be honest with you about a possible furnace replacement. We value our time and your money––we don’t want to perform repairs or service on an appliance that is in need of replacement.

If you do need a furnace replacement, we know how overwhelming it can be. Here are some of the frequently asked questions about furnaces that we get from some of our Modesto residents:

What Are The Different Types Of Furnaces?

Single Stage: A single-stage furnace has only one stage of operation. It can either be turned on or turned off.

Two Stage: A two-stage furnace has two settings––full and half speed. This is a more efficient way to heat and provides for better comfort, because it can move the air at a slower pace.

Variable Stage or Modulating: A variable-stage or modulating furnace modulates the speed and heat output based on the temperature outside and the desired comfort level. This furnace only works as much as you need it, making this type the most energy-efficient type of furnace.

What Is AFUE?

AFUE, or Annualized Fuel Utilization Efficiency, is a measure of furnace-heating efficiency. The higher the AFUE, the more efficient the furnace.

What Size Furnace Do I Need?

We can calculate the correct size furnace for your home. The number of BTUs, or British Thermal Units, needed to heat your home is dependent on a number of variables. Contrary to what you might think, a bigger furnace may not necessarily mean more heating power for your home. Call us at Valley Air Conditioning & Heating, and we can set up an appointment to calculate the furnace size you might need.

“Felipe arrived to perform my HVAC maintenance on the new system I had installed last year. He was very respectful and confidently answered all my questions. While here I inquired about the MARS surge protector. He thoroughly explained the purpose and advantages of having the device on my unit. I decided to have one installed and since he had one on his truck he installed it while he was here eliminating the need for another service call. Once again, great friendly service from a Valley Air Conditioning technician!”

“Shawn is a superb tech. The Barnett family name is well known in the area. He was so patient and we face timed the entire process with the landlord who is an electrical engineer. Furnace repaired. Works beautifully. Swapped out the bad main board, replaced a voltage regulator. AC needed replacement so we’re on order for a Payne unit. I highly recommend sticking with the professional techs. HVAC can be complex. Valley has the the technicians and the tools to get the job done correctly. Highly recommended!.”

- June N.

Gas Furnace Replacement in Manteca, CA 95337

“Your team did a great Job! They were able to remove my old furnace (in the attic) down through my existing attic access without having to cut a new hole in the ceiling. They installed the new furnace and had it running by a little after noon. They cleaned up after themselves and removed all of the old parts and pieces. The new furnace/air conditioner appears to have more power and really puts the air out. It's only been running for one day now but so far we are very pleased with the unit.”
