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 Zionsville, IN 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.

How Much Money Can a New Furnace Save You?

Our AFUE energy savings calculator can help determine how much you could save on your utility bills. Simply enter your current unit's AFUE value and compare it to a newer, more efficient system. You can even customize it to better match your home's system for a more accurate calculation.

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 JL Anderson Heating & Cooling, and we can set up an appointment to calculate the furnace size you might need.

Gas Furnace Installation in West Lafayette, IN 47906

“We had decided to replace our 25+ yr gas furnace and air conditioner and have installed a more efficient system. Joe Kollman met with us and explained the different options for the Trane gas furnaces and air conditioners. He answered all our questions and provided a detailed estimate for the services. Within a couple of weeks during the month of February, Craig Irvin and his apprentice arrived as scheduled to install both units in two days. The furnace was installed first and without any real inconvenience to us was completed by the end of the work day. The air conditioner was installed the next day. Both associates were professional, courteous, and health safety during the entire time that they were working in our home. They were timely in their work and cleared away any of the debris from the installation. Since the installation, we had some below zero temperatures, and the new Trane furnace kept the whole house (over 4000 sq. ft.) at a comfortable temperature. I would recommend Anderson Heating & Cooling and their associates. We are very happy with our Trane system.”
