Top 7 HVAC companies in San Bernardino, California

Cost data in San Bernardino

A full residential HVAC system replacement in San Bernardino typically falls between $11,200 and $13,900 according to one published schedule. A second set of 2025 invoiced figures shows an average of $23,465 with the upper quartile reaching $33,723. Labor is listed at $165 per hour. Permit fees range from $250 to $700. The two sources diverge sharply on the central tendency, which itself signals wide variation by equipment tier and job complexity. Both figures sit above national benchmarks, consistent with the high-cost tier noted for the area.

The shortlist

This shortlist is built from public listing data, not a review of work performed. Companies are ranked by a Bayesian-adjusted rating that pulls each star rating toward the national mean of 4.764 until review volume supports an independent score.

Alpha Air Conditioning Experts

Alpha Air Conditioning Experts operates from 1602 E Highland Ave, San Bernardino, CA 92404 and lists (909) 953-8492. Its Services category and published 24/7 availability together point to a firm oriented toward direct residential service calls. The raw 5.0 rating from seven reviews adjusts downward to 4.869 because the modest review count still receives shrinkage toward 4.764. The score before tie-breakers sits at 4.809. Those seven reviews cannot reveal consistency across larger job volumes or performance on complex Title 24 retrofits.

All in One HVAC Services San Bernardino CA

All in One HVAC Services San Bernardino CA lists its address as 3541 Laurel Ct, San Bernardino, CA 92404 and can be reached at (909) 872-8670. The General contractor category combined with 24/7 availability suggests broad service coverage rather than narrow HVAC specialization. Its raw 5.0 from seven reviews is pulled to an adjusted 4.829, still above the 4.764 mean, with the pre-tie-breaker value at 4.809. Seven reviews leave open questions about performance on larger commercial projects.

Next Level Heating And Cooling

Next Level Heating And Cooling is located at 350 E Commercial Rd #106, San Bernardino, CA 92408 and lists the number (714) 225-1859. Its General contractor listing and single review together indicate limited public signal depth. The raw 5.0 from one review adjusts to 4.812, reflecting strong shrinkage toward the national mean of 4.764. The pre-tie-breaker score is 4.772. A single review supplies almost no information on repeat business or seasonal workload handling.

Blm Heating & Air Conditioning

Blm Heating & Air Conditioning operates from 802 N Mountain View Ave, San Bernardino, CA 92401 and can be contacted at (909) 760-1365. The General contractor category and absence of 24/7 notation suggest standard daytime scheduling. Its raw 5.0 from five reviews receives only modest downward adjustment to 4.798, landing just above the 4.764 mean. The score before tie-breakers equals 4.798. Five reviews cannot demonstrate reliability on the HERS verification steps now required for rebates.

Alliance Heating & Air Conditioning

Alliance Heating & Air Conditioning lists 185 W 40th St, San Bernardino, CA 92407 and the phone (909) 404-7561. Its General contractor category implies it handles mixed residential and light commercial work. The raw 5.0 from four reviews adjusts to 4.792. The pre-tie-breaker score matches 4.792. Four reviews leave the performance record thin on multi-system or heat-pump jobs.

Bird Refrigeration

Bird Refrigeration is situated at 109 4th St, San Bernardino, CA 92410 and lists (909) 905-5622. The General contractor listing and single review again indicate sparse public data. Its raw 5.0 from one review is adjusted to 4.772, only 0.008 above the national mean. The score before tie-breakers is 4.772. One review offers almost no insight into long-term service response or warranty work.

Therma-Pro Mechanical Services, Inc.

Therma-Pro Mechanical Services, Inc. operates from 2150 W Rialto Ave, San Bernardino, CA 92410 and can be reached at (909) 218-3622. Its General contractor category plus a published website suggest some emphasis on mechanical systems. The raw 4.5 from eight reviews is lifted to 4.748 because the count remains small relative to the national mean of 4.764. The pre-tie-breaker value is 4.708. Eight reviews still leave open questions about consistency on coastal versus inland job sites.

Licensing and permits

The Contractors State License Board (CSLB) issues the required C-20 Warm-Air Heating, Ventilating and Air-Conditioning license at the state level. That classification covers installation, repair and replacement of warm-air heating and cooling systems. A $25,000 contractor license bond is mandatory under Business and Professions Code section 7071.6. Workers compensation insurance is required whenever employees are present; no exemption filing is permitted for C-20 or C-38 holders. The state does not require general liability insurance beyond the bond, though individual cities may impose additional rules. Building permits for furnace or air-conditioner replacements are issued by the local city or county building department rather than by CSLB. Homeowners must therefore confirm permit requirements directly with the jurisdiction where the work occurs.

Climate considerations

San Bernardino sits in Title 24 climate zones rather than IECC designations, with the dominant zones labeled 3B and 3C under a dry-to-marine moisture regime. Heating degree days total 2,200 while cooling degree days reach 1,000, producing a balanced mixed load profile. Design temperatures are 44 °F in winter and 89 °F in summer. Low inland humidity reduces latent loads compared with coastal markets. Natural gas remains the primary heating fuel, yet state code now favors heat pumps. Central air saturation is moderate to high. Equipment must therefore handle both heating and cooling seasons without oversizing, especially on the hotter inland side of the county where summer peaks drive service demand.

Incentives available in 2026

California Home Energy Rebates through the CEC and HEEHRA remain available in Phase 1, offering up to $8,000 for qualifying heat pumps. No statewide income-tax credit exists for HVAC equipment, although SGIP continues for heat-pump water heaters. Utility programs such as TECH Clean California and Golden State Rebates supply $1,000 to $3,000 or more. All major utilities participate. TECH requires the installer to be an enrolled contractor, which narrows the pool of eligible firms. With federal 25C and 25D credits expired, the only surviving federal incentive is the 30 % 48E ITC limited to commercial or third-party-owned systems. These rules together mean homeowners must first confirm that any candidate installer holds both a C-20 license and TECH enrollment before discussing equipment options.

How to choose

Check the CSLB license lookup before any site visit. Confirm the firm is enrolled in TECH if a rebate is planned. Ask which HERS rater will perform the required duct-leakage and refrigerant-charge tests and who pays for re-testing if the first attempt fails. Compare the two published cost ranges against the specific equipment tier quoted. Verify 24/7 availability only for firms that explicitly list it. Finally, request references for recent Title 24 projects in the same zip code.
