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 San Jose, CA 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 Air Care Heating & Cooling, and we can set up an appointment to calculate the furnace size you might need.

“Sergio and Juan did and excellent job in the installation of the gas furnace and AC coil.. Although they did not complete the job in one day due to difficulty of the configuration and location of the existing furnace, Sergio came in the next day to finish the job. He is very careful to make sure everything is in the proper order and made good seals in all jointing area. After completion everything works fine.. Sergio is very professional and answered all my questions.”

“I found Air Care from a recommendation on my local elist. Great find! Air Care was quite willing to work on my rather ancient furnace, quickly diagnosing the problem and scheduling a return visit to complete the repair with a special order part before they left from their initial diagnostic visit.

Other HVAC contractors have a will-get-to-you-when-we-get-to-you attitude. Air Care was completely on top of communication and scheduling…no surprises…a big plus! Air Care arrived exactly on time and ready to rumble on both of their pre-scheduled visits.

During the initial diagnostic visit our technician Brian P. tried several heroic measures to restore operation–only concluding that a new part was required after significant effort to restore our heat the same day. Brian answered all of our many questions and respected our desire for social distancing during the pandemic.

But ultimately the measure of success is the repair itself. When Brian P. returned to install the new part he did not relent when the ancient beast refused to give up her hold on the misbehaving component. He persisted until the physically challenging replacement was completed and our heat restored during the coldest days of December.

We will certainly be calling Air Care when our (inevitable) future HVAC issues arise. I recommend them enthusiaistically.”
