How long do furnaces typically last?

Most furnaces last 15-20 years with regular maintenance. If yours is approaching that age or needs frequent repairs, it may be time to consider a replacement.

What size furnace do I need for my home?

Furnace size depends on your home's square footage, insulation, and layout. We assess your home to recommend a properly sized furnace for even, efficient heating.

How often should I schedule furnace maintenance?

We recommend a maintenance visit once a year, ideally before the start of the heating season, to keep your furnace running safely and efficiently.

What are common signs my furnace needs repair?

Watch for ignition or pilot light problems, thermostat issues, weak airflow, or a blower that runs without producing warm air — all signs it's time to call for service.

Should I repair or replace my furnace?

It depends on the furnace's age, repair history, and efficiency. We'll give you an honest assessment and help you weigh the cost of repair against the long-term value of a new system.
