Top 7 HVAC companies in Denton, Texas

Denton County’s population exceeds 887,000 and sits in a cooling-dominant climate zone. Public listings supply the data for this ranking. Companies receive a Bayesian-adjusted score that pulls raw star ratings toward the national mean of 4.764 until review counts grow large enough to stand alone. Additional tie-breakers favor a public website, HVAC-specialist listing, and published 24/7 availability. This is a shortlist built from public listing data, not a review of work performed.

The shortlist

HVAC Repair Pros

HVAC Repair Pros operates from 7408 Riverchase Trail, Denton, TX 76210 and lists (940) 978-3767. Its general-contractor category and lack of 24/7 notation suggest daytime commercial and residential work. Fifteen reviews produced a raw rating of 5.0 that the model adjusted downward to 4.883 because the count remains modest relative to the national mean. The firm also carries a public website that supplied the final tie-breaker. These figures cannot reveal whether the fifteen reviews cover recent installations or only service calls.

Karma Air

Karma Air lists its address as 4135 Boxwood Dr, Denton, TX 76208 and phone as (469) 987-1313. The single review at 5.0 received an adjusted score of 4.832 after the model pulled it toward 4.764. Published 24/7 availability and a public website supplied the two tie-breakers that placed it ahead of firms with more reviews but lower availability signals. The numbers give no indication of how the lone review was collected or whether the firm maintains inventory for same-day parts.

One Hour Heat & AC Denton

One Hour Heat & AC Denton is located at 414 W Parkway St Ste 201, Denton, TX 76201 and can be reached at (945) 260-3108. Nineteen reviews yielded a raw 4.7 that adjusted to 4.799. Both 24/7 availability and a public website contributed to its position. The adjustment moved the score upward from what a larger sample at the same raw rating would have produced. The data do not disclose how many of the nineteen reviews involved full system replacements versus repairs.

Liberty Heating Services

Liberty Heating Services lists 221 S Locust St, Denton, TX 76201 and (817) 772-8715. Two reviews at 5.0 produced an adjusted score of 4.799 after upward movement toward the mean. Published 24/7 availability served as the sole tie-breaker. With so few reviews the model exerts stronger pull, which is why the adjusted figure sits below the raw rating. The numbers cannot show whether the firm carries its own service trucks or subcontracts labor.

Merit Services

Merit Services operates from 204 N Mayhill Rd, Denton, TX 76208 and lists (972) 245-2848. Nine reviews at 4.6 adjusted upward to 4.786 because the raw score sat below the national mean. A public website and 24/7 availability supplied the tie-breakers. The modest review count kept the adjustment noticeable. These figures reveal nothing about the proportion of commercial versus residential jobs completed.

Elite HVAC Repair Denton

Elite HVAC Repair Denton lists 717 N Elm St, Denton, TX 76201 and (940) 413-0948. Three reviews at 4.0 moved upward to an adjusted 4.715 once pulled toward 4.764. Published 24/7 availability provided the only tie-breaker. The small sample size produced a larger adjustment than firms with more reviews. The data cannot indicate whether the three reviews reflect recent work or older listings still visible online.

Denton Air Conditioning and Heating

Denton Air Conditioning and Heating is located at 110 Cardinal Dr, Denton, TX 76209 and reachable at (940) 260-8190. Seventeen reviews at 4.1 produced an adjusted score of 4.524 with no additional tie-breakers recorded. The raw rating sat below the mean, so the model pulled the score upward, yet the final position remained last. The review count is large enough that further reviews would change the score only modestly. These numbers supply no information on response times during the summer peak.

How to choose

Verify every firm’s current TDLR ACR license class through the public lookup before requesting a quote. Compare the exact review count behind any star rating rather than the displayed number alone. Confirm whether the listing shows a public website or 24/7 availability when after-hours service matters. Ask for references from recent full-system replacements rather than repairs. Request written confirmation that the contractor will pull the required local mechanical permit.

Installed costs

One data source places a typical full-system installation between $8,100 and $9,900. A second source reports an invoiced average of $13,050 with the upper quartile reaching $21,118. Labor is listed at $100 per hour. Permit fees range from $100 to $400. Both sources are cited because the figures diverge. The difference likely reflects variation in equipment efficiency, duct modifications, and whether the job included electrical upgrades.

Local climate demands

Denton falls in IECC zones 2A/3A with 1,700 heating degree days and 2,900 cooling degree days. The load profile is cooling-dominant, with summer design temperatures of 96 °F and winter design temperatures of 32 °F. Extreme humidity on the eastern side of the county requires equipment sized for both latent and sensible loads. Central air conditioning saturation is near-universal, and natural gas or electricity supplies primary heating. Heat pumps are rated excellent for the market, yet Winter Storm Uri demonstrated that heating capacity must be verified for rare but severe cold events.

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 covers cooling systems 25 tons and under and heating systems 1.5 million BTU/hour and under, each with required endorsements. Class A requires commercial general liability insurance of $300,000 per occurrence and $600,000 aggregate. Class B requires $100,000 per occurrence and $200,000 aggregate. ACR licensure is statewide, but mechanical permits for residential changeouts are issued by the local city or county building department; some municipalities add their own HVAC registration.

Available incentives

The Texas Home Energy Rebates program remains conditionally approved with a planned launch in 2026 and a maximum heat pump rebate of $8,000. Utility programs through Oncor and others offer $200 to $1,800 but require a registered contractor. No federal residential HVAC tax credit exists for 2026. The largest federal allocation in the country moves slowly, so homeowners should prioritize installers already enrolled in utility networks to capture any 2026 state or local rebates that do launch.

Homeowners should cross-check every license number directly with TDLR and request current insurance certificates before signing any contract.
