What affects cost?

The cost to install a furnace depends on several factors, including:

  • Equipment size. Furnaces are sized in "BTUs". The larger the home, the more BTU output is typically needed, which increases cost.
  • Efficiency. Furnace efficiency is measured in "AFUE". The higher the AFUE, the more expensive the system.
  • System add-ons. Some homeowners choose to add on comfort features, like whole-home filtration or monitoring equipment, which increases cost.
  • Ductwork modifications. You'll pay more if you have old or improperly sized ductwork that needs modifications.
  • Company you hire. You’ll pay more for skilled, experienced techs who know how to properly install your furnace.

“...worked until after dark to ensure our system was fully installed.“

Our heat went out during the freeze last winter. We got a few quotes and decided on JW. The salesman wasn't pushy, spent time answering all questions. The professional technicians worked until after dark to ensure our system was fully installed. We were very pleased overall.
