Top 7 HVAC companies in Galveston, Texas

Galveston County sits in a cooling-dominant climate where summer peaks drive most service calls. Installed costs for full systems average between eight and twenty-one thousand dollars depending on source. State licensing runs through TDLR yet local permits vary by city. The shortlist below draws only from public listing data and applies a Bayesian adjustment that pulls every raw rating toward the national mean of 4.764.

How to choose

A homeowner facing a four- to twelve-thousand-dollar decision needs more than star ratings. The ranking uses a Bayesian-adjusted score that shrinks extreme values from small sample sizes toward the national mean. Additional weight goes to a public website and published 24/7 availability. Every firm listed here holds a general-contractor category; none is flagged as an HVAC-only specialist. Readers should verify current TDLR ACR license class and insurance limits directly at the state lookup before any deposit.

The shortlist

Kovich A/C & Heating

Kovich A/C & Heating operates from 8015 Bayside Ave Ste. B, Galveston, TX 77554 and lists (409) 770-3958. Its seven reviews produced a perfect 5.0 raw rating that the model adjusted downward to 4.809. The pull toward 4.764 reflects the modest review count. The firm appears as a general contractor yet publishes both a website and 24/7 availability. These two tie-breakers secured first place. Numbers alone cannot reveal workmanship on larger coastal installations or response times during hurricane season.

Air duct Cleaning Service Galveston

Air duct Cleaning Service Galveston lists a single five-star review and an adjusted score of 4.772 from its address at 4134 San Jacinto Dr, Galveston, TX 77554. The phone number is (409) 295-2303. The firm carries a services listing and advertises 24/7 availability, which supplied the only tie-breaker applied. Its raw rating sat above the national mean, so the adjustment moved it downward. The low review volume leaves open questions about consistency on full equipment changeouts rather than duct work alone.

Air Control A/C + Heating

Air Control A/C + Heating sits at 3614 Yale St, Galveston, TX 77554 with phone (409) 744-0774. Two reviews yielded a 4.5 raw rating that rose slightly to 4.748 after adjustment. The firm’s general-contractor listing and public website earned the single tie-breaker. Because its raw score fell below the national mean, the model lifted the adjusted figure. Limited reviews prevent any conclusion about long-term reliability on humidity-control jobs typical of the Gulf Coast.

Halcumb Air Conditioning & Refrigeration

Halcumb Air Conditioning & Refrigeration maintains one five-star review and an adjusted rating of 4.772 at 2221 71st St, Galveston, TX 77551. Reach the firm at (409) 744-5815. No tie-breakers applied. The raw score above the mean produced a modest downward adjustment. Its general-contractor category offers no signal of refrigeration specialization despite the name. Review depth remains too thin to indicate performance on commercial refrigeration loads.

Burt's Air Conditioning & Heating Services

Burt's Air Conditioning & Heating Services posted four reviews averaging 4.8 stars from 2717 34th Ave N, Texas City, TX 77590. The phone is (409) 206-9713. The adjusted score settled at 4.768. The raw rating exceeded the national mean by a small margin, so the Bayesian step pulled it downward. No website or 24/7 listing appears. Four reviews leave unanswered questions about performance during peak summer outages.

Right Temp Air and Heat Galveston

Right Temp Air and Heat Galveston holds six reviews averaging 4.5 stars at 3700 83rd St, Galveston, TX 77554. Call (409) 255-6432. The adjusted rating reached 4.72. Its raw score below the mean received an upward Bayesian correction. No additional tie-breakers applied. The general-contractor listing supplies no further specialization data. Six reviews still leave room for variability on coastal corrosion issues.

Sears Heating and Air Conditioning

Sears Heating and Air Conditioning recorded one one-star review yet reached an adjusted score of 4.643 after the model lifted the raw rating toward the national mean. The address is 722 21st St, Galveston, TX 77550 and the phone is (346) 308-6568. A public website supplied the sole tie-breaker. The single review offers no usable performance signal.

Cost

Installed-cost data show a modeled typical range of $8,100 to $9,900 for a full system. 2025 invoiced averages reached $13,050, with the upper quartile at $21,118. Labor is listed at $100 per hour. Permit fees run $100 to $400. Both sources are cited because the invoiced figures sit well above the modeled range. The gap may reflect differences in equipment tier, duct modifications or coastal corrosion upgrades common in Galveston County.

Licensing and permits

The Texas Department of Licensing and Regulation (TDLR) — Air Conditioning and Refrigeration Contractors (ACR) Program issues statewide Class A and Class B licenses. Class A covers any size unit; Class B is limited to cooling systems 25 tons and under and heating systems 1.5 million BTU/hour and under. Both classes require endorsements for environmental air conditioning, commercial refrigeration or process cooling. Class A insurance minimums are $300,000 per occurrence and $600,000 aggregate; Class B limits are lower. ACR licensure is statewide, yet mechanical permits for furnace or AC changeouts are issued by the local city or county building department. Some municipalities add their own supplemental HVAC registration.

Incentives

Texas Home Energy Rebates remain conditionally approved for a 2026 launch with a planned $8,000 heat-pump maximum. Utility programs through Oncor, CenterPoint and others offer $200 to $1,800 but require a registered contractor. No state income tax exists, so no state HVAC credit applies. Federal 25C and 25D credits expired at the end of 2025. The 48E commercial credit survives only for qualifying third-party systems. Homeowners must therefore confirm contractor participation in any active utility network before proceeding.

Climate

Galveston County falls inside IECC zones 2A/3A with extreme Gulf humidity. Heating degree days total 1,700 while cooling degree days reach 2,900, confirming a strongly cooling-dominant load. Summer design temperature is 96 °F and winter design is 32 °F. Near-universal central AC saturation and documented humidity loads mean equipment must handle latent cooling and corrosion. Winter Storm Uri previously exposed heating-capacity shortfalls, so dual-fuel or adequately sized heat-pump selections remain relevant despite the mild heating season.
