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 Erie, PA 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 Nerthling's Heating and Air Conditioning, and we can set up an appointment to calculate the furnace size you might need.

“Cameron is a highly professional young man. Answered all my many questions to my understanding. He found and completed the repair in a reasonable time. Cleaned up on completion. Also sent announcement and his photo prior to arrival. Kudos to our electrician Earl Cameron for recommending Nerthling. You’ll be hearing from us in the fall”.

“I highly recommend Nerthling’s. I called them because our furnace was shutting off not keeping the house at a consistent temperature. I called around 8 AM and they sent two technicians out by mid morning. When I called the person I spoke with clearly explained what I should expect the diagnostic to consist of and what the cost would be. The young men that come were professional and courteous. They did a diagnostic and found that we did need a fan/ blower replaced which they were able to do same day. The cost was reasonable and service was excellent and honest.”

“Nerthlings is the way to go!! My husband and I purchased a hundred year old house that needed a new furnace and central air conditioning. We were very concerned about how this would be in terms of what we needed, how this is going to work in such an older home and what financing was available. From the finances to the assessment to the installation professional, kind, personable. Even from the initial phone call when you call the office they are simply amazing! Even after everything is installed they want to make sure that everything is running smoothly. And any complications we could call them at 2 o’clock in the morning and they would make sure that they were available to help with anything that is needed. I am so impressed with them I cannot say in words express enough how much this has been such a blessing to my husband and I. If you want a new air conditioner or furnace, I highly recommend them!! Words cannot express my appreciation for them”
