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.

“Our appointment window was between 12:00PM and 3:00PM; Miss Chloe arrived early and finished our annual preventative maintenance service very efficiently and professionally. She was very friendly, respectful and seemed to really enjoy her job and meeting people of varied backgrounds. I look forward to asking for her specifically when next year’s routine maintenance for our Anderson-installed furnace.”

“On 1/15/24 I left a dissatisfied review about being ineligible for after hours service even though I’ve been a long standing customer. Joe called me back the same evening and apologized and explained the why behind the new policy. Maintenance plan customers are covered after hours because too many off the street consumers looking for a quick fix were taking advantage of them leaving them stretched to service their loyal customers.
This makes perfect sense to me. Joe sent the service technician Tim out and he fixed my furnace in short order. I enrolled in the maintenance plan today. I’m always willing to pay for quality, service, security and dependability. I just didn’t know. This all worked out very well in the end. Thank you Joe and Tim!”

“I have been loyal to Anderson, but they have not been loyal to me. I hired them to install complete HVAC/heat pump+duct work in my last two homes. I got home from work tonight to no heat. It’s 7 degrees F outside. I called for after hours service, which I hate to do anyway, but got a call back from the service person stating that their current policy is “no after hours service unless you are subcribed to our maintenance program”. If I would have known about the quid pro quo arrangement I would have enrolled in the service agreement. For MANY reasons, I am an unhappy repeat customer tonight!”
