How do I know when it’s time to replace my furnace?

If your furnace is over 15 years old, needs frequent repairs, or can’t heat your home evenly, it may be time for a replacement. A new system can improve comfort and lower your energy bills.

What size furnace do I need for my home?

The correct furnace size depends on your home’s square footage, insulation, and layout. Our technicians perform a detailed load calculation to ensure your new system is properly sized for efficient heating.

How long does furnace installation take?

Most furnace installations can be completed in one day. Complex setups, such as those involving new ductwork or fuel conversions, may take a little longer.

Will a new furnace help lower my energy costs?

Yes. Modern furnaces are designed to use less fuel while producing more consistent heat. Upgrading to a high-efficiency unit can significantly reduce your monthly heating expenses.

Do you remove my old furnace during installation?

Absolutely. Our team safely removes your old system, disposes of it properly, and ensures your new furnace is installed cleanly and efficiently with minimal disruption to your home.

How much does it cost to install a new furnace?

Furnace installation typically starts at $6,500 for a gas furnace and $7,000 for an oil furnace. Your final price can vary based on furnace size, efficiency level, venting requirements, and any ductwork or code upgrades needed. These prices are general guidance—not a guaranteed quote.

Corey Menard is a STELLAR human being as well as an EXPERT HVAC technician! He cheerfully and swiftly diagnosed an in-wall heating pipe burst, repaired it, and added a much-needed shut-off valve for one of my (three) heating zones. My English language dictionary does NOT contain the words I need to express my gratitude toward him, or express my gratitude to Landry for sending Corey to my home on Wednesday 02/11/2026. Thank Corey, thank you, and thank Corey!
