Top 7 HVAC companies in Dallas, Texas

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 it has enough reviews to stand on its own. Small tie-breakers apply for a public website, HVAC-specialist listing category, and published 24/7 availability.

Air Cool Pro –Heating & Air Conditioning

Air Cool Pro –Heating & Air Conditioning operates from 18383 Gallery Dr, Dallas, TX 75252 and lists (945) 232-8766. Its 52 reviews yield a raw 5 rating that the ranking adjusted down to 4.974 because the national mean sits at 4.764 and 52 reviews still allow modest shrinkage. The firm appears as a general contractor yet publishes 24/7 availability and maintains a public website, supplying the two tie-breakers that lifted its pre-tie-breaker score of 4.914. These numbers cannot reveal whether the firm holds the Class A or Class B ACR license required for larger systems.

Nuvo HVAC

Nuvo HVAC lists 14 reviews at a raw 5 that adjusted to 4.899, still above the 4.764 mean but pulled downward less aggressively than a larger sample would allow. It operates from 6060 N Central Expy Ste 206, Dallas, TX 75206 and can be reached at (214) 444-6886. The firm appears as a general contractor, lists 24/7 availability and a public website, and recorded a pre-tie-breaker score of 4.839. Limited review depth leaves open questions about consistency across varied job sizes.

TexAir HVAC Services Dallas

TexAir HVAC Services Dallas shows only one review at raw 5, adjusted to 4.832. The single review produces the largest downward pull toward 4.764 among the top three, yet the firm still ranks third after tie-breakers for its public website and 24/7 listing. It is based at 5050 Quorum Dr Ste 852, Dallas, TX 75254 and answers (972) 424-1971. Its general-contractor category supplies no further signals about equipment specialization.

Dallas HVAC Repair Service

Dallas HVAC Repair Service records four reviews at raw 4.8 that the adjustment lifted slightly to 4.808 because the rating sits above the 4.764 mean. The firm operates from 325 North St. Paul Street Ste 5200, Dallas, TX 75201 and lists (945) 303-8465. It lacks 24/7 publication, so only the website tie-breaker applied, producing a pre-tie-breaker score of 4.768. Four reviews leave performance on larger installations untested.

Silver Spur Air, Heating, & Plumbing of Dallas

Silver Spur Air, Heating, & Plumbing of Dallas posted 47 reviews at raw 4.7, adjusted upward to 4.765 because the rating falls below the national mean of 4.764. The address is 4300 N Central Expy #290, Dallas, TX 75206 and the phone is (972) 290-1996. The firm shows as a general contractor without 24/7 availability, so only the website contributed to its pre-tie-breaker score of 4.725. Forty-seven reviews still permit noticeable movement toward the mean.

Climate Tech Air Conditioning & Heating, LLC

Climate Tech Air Conditioning & Heating, LLC carries 36 reviews at raw 4.5 that adjusted upward to 4.68. The address is 13657 S Jupiter Rd #111, Dallas, TX 75238 and the number is (972) 254-6283. Published 24/7 availability and a public website supplied both tie-breakers despite the general-contractor category, moving its pre-tie-breaker score to 4.62. Thirty-six reviews remain small enough that further data could shift placement.

Dalco Air Conditioning & Plumbing

Dalco Air Conditioning & Plumbing lists 43 reviews at raw 4.4, adjusted upward to 4.61. It is located at 7310 Military Pkwy, Dallas, TX 75227 and reachable at (214) 381-1445. The combination of 24/7 availability and a website again supplied tie-breakers inside the general-contractor category, yielding a pre-tie-breaker score of 4.55. Forty-three reviews still allow the Bayesian adjustment to close much of the gap to the national mean.

How to choose

The Bayesian adjustment penalizes small samples more than large ones, so a 5.0 from one review cannot outrank a 4.7 from dozens. Verify the contractor's TDLR ACR license class matches the tonnage and BTU rating of the planned equipment, then confirm the city or county will issue the required mechanical permit. Participation in utility rebate programs is another filter because those programs restrict payments to registered contractors.

Cost

Installed-cost data for Dallas County show a typical full-system price of $9,000 inside a published range of $8,100-$9,900. A separate 2025 invoice sample reports an average of $13,050 and an upper quartile of $21,118. Labor is stated at $100 per hour. Permit fees range from $100 to $400 depending on the jurisdiction. The two cost sources disagree on central tendency, which itself indicates that final pricing depends on equipment efficiency, duct modifications and whether the job triggers local inspection requirements.

Climate

Dallas sits in IECC zones 2A/3A with 1,700 heating degree days and 2,900 cooling degree days, producing a strongly cooling-dominant load profile. Summer design temperature reaches 96 °F while winter design sits at 32 °F. Extreme humidity prevails east of the county line and becomes drier westward. Central air-conditioning saturation is near universal, yet Winter Storm Uri demonstrated that heating capacity can still fall short during rare cold events. Equipment must therefore handle high latent loads in summer and retain adequate heating output without excessive auxiliary resistance strips.

Licensing and permits

Texas issues ACR contractor licenses at the state level through the Texas Department of Licensing and Regulation (TDLR) Air Conditioning and Refrigeration Contractors Program. Class A covers any size unit; Class B is limited to cooling systems 25 tons and under and heating systems 1.5 million BTU per hour and under, each with Environmental Air Conditioning, Commercial Refrigeration, or Process Cooling/Heating endorsements. Class A minimum insurance is $300,000 per occurrence and $600,000 aggregate; Class B minimums are lower. Building or mechanical permits for furnace or AC changeouts are issued by the local city or county, not the state, and some municipalities add their own HVAC registration.

Incentives

Texas Home Energy Rebates remain conditionally approved with a planned launch in 2026 and a maximum heat-pump rebate of $8,000. No state income tax exists, so no state HVAC tax credit applies. Utility programs through Oncor and others offer $200-$1,800 but require a registered contractor. Federal 25C and 25D credits expired at the end of 2025; only the commercial 48E ITC survives. Homeowners therefore need to confirm whether a contractor participates in the specific utility network before any rebate can be claimed.
