Frequently Asked Questions

How do I know if my furnace needs to be replaced?

Signs include age over 15–20 years, frequent repairs, rising energy bills, uneven heating, or a cracked heat exchanger. We'll give you an honest assessment.

What AFUE rating should I look for?

Standard furnaces run at 80% AFUE; high-efficiency models reach 95–98%. Higher AFUE means lower gas bills — we'll help you calculate the payback period.

How long does furnace installation take?

Most installations are completed in one day — typically 4 to 6 hours for a straightforward replacement.

Do I need to upgrade my ductwork when replacing the furnace?

Not always. We inspect your existing ductwork and let you know if any modifications are needed for proper airflow with the new system.

Yes — we offer flexible financing options with same-day approvals. Ask about current promotions when you schedule your free estimate.
