Furnace & Heating FAQs
My furnace won't turn on — what could be wrong?
Common causes include a tripped breaker, a faulty thermostat, a clogged filter, a bad igniter or flame sensor, or a safety lockout. Call us and we'll diagnose it quickly, with a clear written estimate before any repair.
Should I repair or replace my furnace?
If your furnace is over 15–20 years old, needs frequent repairs, or is showing signs of a cracked heat exchanger, replacement is often safer and more cost-effective. We'll give you an honest recommendation based on your equipment and budget.
How much does a new furnace installation cost?
It depends on the size, efficiency rating, and your home's setup. That's why we provide a transparent, no-pressure estimate with options before any work begins. Financing is available on new installs.
How often should my furnace be serviced?
We recommend a professional tune-up once a year, ideally in fall before heating season. Regular maintenance keeps your system safe, efficient, and less likely to fail on the coldest night.
Do you offer emergency heating service?
Yes. Call us directly for urgent no-heat situations and we'll prioritize your request for same-day service whenever possible.
Do you install heat pumps and high-efficiency systems?
Absolutely. We service and install furnaces, heat pumps, and high-efficiency heating systems from most major brands, including Trane — and can recommend the best fit for your home.
