Equipment, labor, line-set, electrical, code upgrades, haul-away — all in writing before install day. Quote doesn't move on the calendar.

04

GoodLeap Financing

Same-as-cash promo periods or fixed-rate financing. Quick application, instant decision, financing details folded right into your quote.

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 AC system cost?
Standard 3-ton replacements typically run $7,500-$11,500 fully installed (equipment, labor, code upgrades, haul-away). Premium variable-speed systems with heat pumps run $11K-$17K. Quote is in writing before install, no surprises.
Why does sizing matter?
Oversized AC short-cycles, doesn't dehumidify, wears out faster, and costs more upfront. Undersized AC runs nonstop and never quite cools. Manual J heat-load calc is the only way to get it right.
How long does install take?
Most replacements: 1 day. New ductwork or first-time install: 2 days. We'll give you the timeline up front with the 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.
What warranty comes with a new system?
Manufacturer parts warranty (typically 10 years on major components, registration required). Five Star workmanship warranty in writing. We register the equipment for you so the warranty is active day one.
