Heating & Air Conditioning in Folsom, CA

Furnace, air conditioner and heat pump service for Folsom homeowners, from our base nearby in Fair Oaks.

Climate and your system

The weather station near Folsom records only rainfall, so the temperature picture comes from NOAA’s 1991–2020 normals for Sacramento 5 ESE. Winter there is mild: January nights average 41°F and only about 4 nights a year reach freezing, which is easy territory for a heat pump. Summer is the hard part, with a July average high of 94°F.

Folsom (ZIP 95630) sits in Climate Zone 12. Under Title 24, replacing a central system there usually comes with a duct leakage test that an ECC-Rater (formerly a HERS Rater) verifies.

Homes in Folsom

Most of Folsom’s homes are newer: the typical home was built in 1997 and only about one in eight predates 1980. A home built in the late 1990s that still has its original system is now past 25 years of use, so a careful repair-or-replace conversation pays off, especially before the summer heat.

Permits: City of Folsom

The City of Folsom handles HVAC replacements as minor building permits through its online portal, eTRAKiT, where permits are applied for, paid and issued, and inspections are scheduled. The installing contractor normally applies for it. Source: City of Folsom, ePermit Center.

Common questions in Folsom

Yes. In California a building permit is required when an HVAC unit is replaced. In Folsom, residential HVAC permits come from the City of Folsom Community Development Department, and most replacements also require a Title 24 duct leakage test verified by an independent ECC-Rater (formerly HERS Rater). We get the permit and schedule the test for you.

SMUD supplies electricity and PG&E supplies natural gas in Folsom. SMUD’s heat pump and heat pump water heater rebates are paid only when the job is done by a contractor in the SMUD Contractor Network; ask us before you buy so we can confirm whether your project can qualify with us.

Through November 30, 2026 our residential visit and diagnosis is $49 per system, and we waive the $49 fee if you approve the repair. The price is the same on evenings and weekends, and you get a written repair price before any work starts. New installation estimates are free.
