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 Portland, MI 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 ESI Heating, and we can set up an appointment to calculate the furnace size you might need.

Gas Furnace Installation in Portland, MI 48875

““I was impressed with the professionalism of Nick Bengal, Randolph Martin and Mike Charles. They removed my old Lennox 21 V-Pulse furnace and installed a new Amana 97% Efficiency Modulating Variable-Speed Gas Furnace. They installed it as scheduled in a timely manner. They arrived on time and cleaned up after themselves. Randolph and Mike removed the old furnace and had the new furnace operational by the end of the day. My wife and I did not spend a night in the cold. Randolph and Mike were methodical in the installation process. After installing the furnace, Nick helped Randolph and Mike set up the new Amana furnace to work with my Geothermal heating and cooling system. Following completing the integration of the gas furnace and geothermal, Nick instructed me on how the gas furnace, geothermal and zone heating functions. Our home is the most comfortable, from a heating standpoint, it has ever been since moving into the newly built home in 1998. I highly recommend hiring ESI Heating and Cooling Inc. to install and service anyone’s heating and cooling needs.”” – Bruce B.
