HVAC Installation FAQs

How do I know if I need a new system vs. a repair?

If your system is over 12 years old, needs frequent repairs, or your energy bills are rising, replacement usually makes more financial sense. We'll give you an honest assessment — even if it means repairing instead of replacing.

What size AC do I need for my Boise home?

Most Boise homes need 2.5-4 tons depending on square footage, insulation, and window orientation. We perform a Manual J load calculation to determine the exact right size — never guesswork.

How long does installation take?

Most AC or furnace replacements are completed in one day. Full system replacements (including ductwork) may take 2-3 days.

Do you handle permits?

Yes — we pull all required permits from the City of Boise or Ada County. Included in your installation price at no extra cost.
