Replacing an existing furnace

Replacing a furnace involves more than selecting a new unit. The new equipment must work with your home's heating needs, connections and remaining system components. A-1 serves homeowners in Topeka, Lawrence and Northeast Kansas.

If your current furnace is unreliable, start with a diagnosis. Our repair-versus-replacement guide explains how to compare the options without relying on age alone.

Keep, change or upgrade?

Keep what is suitable

Ask whether the existing thermostat, cooling equipment and duct connections are compatible and in suitable condition.

Identify required changes

Get proposed venting, drainage, electrical, gas or duct changes written into the scope. Ask how access and removal will be handled.

Separate optional upgrades

Compare comfort controls, equipment choices and other optional work separately from the items required for the installation.

A before-and-after furnace project

These photos show the same furnace project before and after installation. The supplied project record identifies the replacement as an Amana 96% AFUE, 80,000 BTU furnace. This is one installation example; the appropriate equipment for another home may differ.

Furnace questions

Should I replace the furnace and air conditioner together?

That depends on the condition and compatibility of the existing equipment. Ask for options that clearly identify what remains and what changes.

What should I have ready when I request an estimate?

Share your address, equipment model if available, where the furnace is located, the problem you are experiencing and any recent repair history.

Can I finance a replacement?

Financing is available on qualifying work, subject to approval and applicable terms. Review the financing page or ask when discussing your estimate.
