Top 7 HVAC companies in Merced, California

Merced County sits in California’s Central Valley with a population of 277680. Public records show seven HVAC-related listings that meet the ranking criteria. Review volume remains low across the set, so the Bayesian adjustment pulls every raw score toward the national mean of 4.764. The resulting shortlist supplies concrete addresses, phone numbers and category signals rather than subjective endorsements.

Cost of HVAC work in Merced

A modeled typical full-system install stands at $12,550, bounded by a published range of $11,200 to $13,900. Separate 2025 invoiced data list an average of $23,465 and an upper quartile of $33,723. Labor appears at $165 per hour. Permit fees range from $250 to $700. The two cost sources diverge sharply, with the invoiced average roughly twice the modeled typical price. Both figures come from the same data release dated 2026-08-16, so the gap itself is the usable information for budgeting.

The shortlist

Advanced Heating and Air Contractors

Advanced Heating and Air Contractors operates from 3514 Atwater Blvd, City of Atwater, CA 95301 and lists the phone number (209) 358-7921. Its four reviews produced a raw 5.0 that the adjustment lowered to 4.792 because the score sits above the national mean and the review count is still small. The listing category of general contractor plus a public website supplied the tie-breaker that placed it first. These numbers reveal nothing about how the firm schedules service calls or handles warranty claims.

G P Norton Co

G P Norton Co is located at 90 W Childs Ave, Merced, CA 95341 with the phone number (209) 723-3966. Eight reviews at a raw 5.0 adjusted downward only to 4.814, the smallest movement among the five-star entries because the larger review count gives the rating more weight. The manufacturer category listing supplies no website or 24/7 flag. The numbers cannot indicate whether the firm performs residential service or limits itself to equipment supply.

Air Boss Air-conditioning heating

Air Boss Air-conditioning heating lists the address 23 W Alexander Ave #279, Merced, CA 95348 and the phone number (209) 489-6862. One review at a raw 5.0 moved to an adjusted 4.772 after the mean pull. The general-contractor category and public website supplied the tie-breaker. With so few reviews the adjustment exerts strong influence, and the figures give no information on actual installation volume or crew size.

Diamond Heating & Air

Diamond Heating & Air is reached at 2885 Business Park Way Ste 1A, Merced, CA 95348 by calling (209) 722-7463. Its single review produced the same raw-to-adjusted drop from 5.0 to 4.772 seen in the prior entry. General-contractor status plus a website again provided the tie-breaker. The limited data set leaves open questions about backlog length and parts inventory.

Cooling Heating & Air Conditioning

Cooling Heating & Air Conditioning appears at 900 W 14th St, Merced, CA 95340. No phone number is published. Zero reviews produced an adjusted score exactly at the national mean of 4.764. The general-contractor category and website presence supplied the tie-breaker that kept it in the shortlist. Absence of review data means the ranking rests entirely on the tie-breaker signals.

Rocha’s Electrical, Heating & Cooling

Rocha’s Electrical, Heating & Cooling operates from 723 Nighthawk Ct, Merced, CA 95340 and lists the phone number (209) 564-1394. Four reviews at a raw 5.0 adjusted to 4.792. The electrician category listing supplied no website or 24/7 flag. The adjustment distance is identical to the first-ranked firm because both share the same review count. The numbers say nothing about whether the firm holds C-20 classification in addition to electrical licensing.

Air Eaze Heating & Air Conditioning

Air Eaze Heating & Air Conditioning is located at 1536 W 8th St, Merced, CA 95341 and can be reached at (209) 455-1286. Two reviews produced a raw 4.5 that adjusted upward to 4.748 because the score sits below the national mean. The general-contractor category and website supplied the tie-breaker. The modest review count still allows noticeable movement from the mean, and the figures cannot reveal response times during peak summer demand.

Licensing and permits

California issues HVAC licenses at the state level through the Contractors State License Board. The relevant classification is C-20 Warm-Air Heating, Ventilating and Air-Conditioning. A $25,000 contractor’s license bond is required by statute, and workers’ compensation insurance must be carried whenever employees are present. No employee exemption filing is permitted for C-20 work. Building permits for residential changeouts are issued by the local city or county building department, not by the CSLB. Title 24 compliance and mandatory HERS third-party verification of duct leakage and refrigerant charge apply to every permitted job.

Climate demands in Merced County

Merced County falls within IECC zones 2B-6B but uses California’s own Title 24 climate zones rather than standard IECC designations. The dominant zones are 3B and 3C with a dry moisture regime. Heating degree days total 2200 and cooling degree days total 1000, producing a balanced mixed load profile. Winter design temperature is 44 °F and summer design temperature is 89 °F. Low humidity reduces latent loads, yet the Central Valley remains strongly cooling-dominant in summer. Equipment must therefore be sized for both winter heating and substantial summer cooling while meeting strict Title 24 efficiency and verification rules.

Available incentives

California Home Energy Rebates remain available in Phase 1, offering up to $8,000 for qualifying heat pumps. No statewide HVAC income-tax credit exists, although SGIP covers heat-pump water heaters. Utility programs through PG&E and others can add $1,000 to $3,000 or more. All major incentive pathways require an enrolled or participating contractor. The 25C and 25D federal tax credits expired at the end of 2025, leaving only the commercial 48E ITC for third-party-owned systems. Homeowners must therefore select an installer already inside the TECH Clean California network to access the largest rebates.

How to choose an installer

Verify the C-20 license on the CSLB lookup site before any site visit. Confirm which HERS rater will perform the required duct-leakage and refrigerant-charge tests and ask who pays for a re-test if the first inspection fails. Request written confirmation that the firm is enrolled in the TECH network if rebate funds are part of the budget. Compare the published labor rate against the two cost sources to judge whether a quoted price aligns with county norms. Finally, ask for the exact permit jurisdiction and expected timeline for both installation and final inspection.
