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.

Removal & Install

Remove the old equipment, set the new condenser and air handler, and seal or replace ductwork as needed.

Test & Clean

Charge the system, verify airflow and temperature split, set the thermostat, and haul the old unit away.

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.

 Trustindex verifies that the original source of the review is Google. Moses team helped us converting our backyard to a beautiful sitting area. Moses helped a lot with arranging everything and consultation. They finished the job in just a few days without cutting corners and exactly as we asked them to do. Although they were not cheap, but I think their quality of work was worth the money.

 Trustindex verifies that the original source of the review is Google. We had a wonderful experience working with Manny on our landscaping project.
The quality of their work was outstanding.
Everything was completed to a high standard, and the attention to detail really showed in the final result.
Perhaps most importantly, they finished the project a few days ahead of schedule, which exceeded our expectations.
Overall, a very professional and reliable team, we would definitely work with them again!!

 Trustindex verifies that the original source of the review is Google. Our landscaping project was just finished by West Coast Home Remodeling. After a lot of confusion on our end, we are very happy with the final design and the way it came out.
Zack really helped us understand what will work for our vision, needs and budget.
The whole yard feels like a proper hangout spot instead of unused space and that’s exactly what we were aiming for!

 Trustindex verifies that the original source of the review is Google. Shawn and the team worked very quickly and professionally to transform our entire backyard into a kid friendly paradise (removed an old patio and dead grass and installed patio pavers, turf, DG, hedges). There were a few instances where things weren’t exactly as we wanted them, and Shawn was quick to address to our satisfaction. I’ve already recommended the team to others who are looking to do yard transformations.
