Common questions

Straight answers, no fluff.

These are the questions our techs actually get asked on the phone every day.

How much does a new furnace cost?
Standard 80% efficiency furnaces run $4,500-$7,500 fully installed. 95%+ high-efficiency runs $6,500-$10,000. Variable-speed premium models $9,000-$13,000. Quote is in writing before install — no surprises.
Should I get a high-efficiency furnace in Southern Utah?
Honest answer: probably not. Mild Southern Utah winters mean lower run hours, so the energy savings from a 95% AFUE vs 80% AFUE often don't pay back the price difference. We'll do the math with you and recommend honestly.
Should I consider a heat pump instead?
Possibly yes. Heat pumps work well down to ~30°F, which covers 99% of our winter days. They double as your AC AND qualify for federal tax credits. We'll compare apples-to-apples with a furnace replacement.
How long does install take?
Most replacements: 1 day. Larger projects (new gas line, new flue, ductwork): 1-2 days. Timeline given up front with quote.
Do you offer financing?
Yes — GoodLeap. Same-as-cash promo periods (12-18 months no interest if paid in full) or fixed-rate plans. Apply on our financing page, instant decision.
