What we install
Six HVAC services in Fontana. One crew.
Every job starts with a load calculation and a fixed bid. No guessing on system size.
AC Installation & Replacement
High-SEER2 central air systems sized by Manual J load calc for Inland Empire heat, not a rule of thumb.
Heat Pumps
All-electric heat-pump systems that cool in summer and heat in winter, with the strongest current rebate eligibility.
Furnaces
High-efficiency gas furnaces for homes keeping a combustion system, installed to code with new venting.
Ductwork & Sealing
New and repaired ducts with mastic-sealed joints. Leaky ducts waste up to 30% of your cooling in IE attics.
Ductless Mini-Splits
Zoned cooling and heating for additions, garages, ADUs and rooms the central system can't keep up with.
Smart Thermostats
WiFi thermostats and zoning controls that cut runtime and let you pre-cool before peak rates.
How it works
Four steps. One to two days. Done right.
Most Fontana system swaps finish in 1-2 working days. New ductwork or zoning adds a day.
Home Assessment
Free visit with a load calculation on your home's size, insulation and sun exposure, plus a fixed bid in 48 hours.
System & Permit
We size and recommend the right SEER2 system, confirm rebate eligibility, and pull the Fontana permit.

Frequently asked
HVAC FAQ - Fontana & Inland Empire.
How much does a new AC system cost in Fontana?
A complete high-efficiency system typically runs $7,000-$14,000 installed, depending on size, SEER2 rating and whether ductwork is replaced. Heat pumps fall in a similar range and often qualify for the largest rebates. We give a fixed bid after the load calc.
What SEER2 rating do I need in the Inland Empire?
For our climate, 15.2 SEER2 is the current minimum, but a 16-18 SEER2 system usually pays back fast given how hard ACs run here. We model the payback for your home.
How do I know what size system I need?
We run a Manual J load calculation. An oversized AC short-cycles and never dehumidifies; an undersized one runs nonstop in July. Correct sizing is the whole game here.
How long does installation take?
Most straight swaps are done in 1-2 days. Adding ductwork, zoning or a mini-split can add a day. We pull permits and schedule inspection.
Do you offer financing?
Yes. Through HFS Financial and HERO/PACE, from $89/mo, 0% APR for 18 months, $0 down for qualified homeowners. Pre-qualify in 60 seconds without affecting your credit.
