Best for Established Track Record
Houk Air Conditioning
Few HVAC companies anywhere can point to more than six decades of continuous operation in a single market. Houk Air Conditioning has been serving Richardson since 1962, making it the longest-running option on this list. The company is family-owned and installs Trane, Carrier, and Lennox equipment, which means technicians are not locked into a single manufacturer when recommending a replacement system. All technicians are NATE-certified company employees rather than subcontractors. For homeowners who place a high value on institutional longevity and multi-brand expertise, Houk is the most straightforward recommendation.

Hammack Service Company
Founded in 1972 and BBB-accredited since 1991, Hammack has maintained an A+ BBB rating across more than five decades of operation. The company holds NATE certification, EPA refrigerant certification, and ACCA membership, and it has earned the Lennox Centurion Award — the highest dealer recognition Lennox grants. If you are specifically purchasing a Lennox system, Hammack’s exclusive focus on that brand means their technicians have unusually concentrated experience with Lennox equipment.

Best for Ductless Mini-Splits
Trotter Air Services
Trotter Air has been family-owned for three generations, going back to 1970. The company holds Armstrong ProTeam dealer status, NATE accreditation, and BBB accreditation. What sets Trotter apart for ductless work specifically is their preferred partnership with Samsung for mini-split systems — a brand that competes at the higher end of the ductless market. If you are adding a room addition, converting a garage, or supplementing an existing ducted system, Trotter’s Samsung focus gives them a concrete specialty most general HVAC contractors lack.

Best for Trane System Buyers
AC Pros
AC Pros has served Richardson and the surrounding area for over 30 years. The company holds Trane Comfort Specialist status, which Trane awards to dealers who meet specific standards for installation quality, customer satisfaction, and technician training. The company is fully licensed and insured and is familiar with local Richardson building codes. For homeowners who have already decided on a Trane system, working with a Trane Comfort Specialist generally means the installing contractor has met Trane’s own benchmarks for that equipment.

Best for 24-Hour Emergency Repairs
Baker Brothers Plumbing, Air & Electric
Baker Brothers was founded in 1945 and carries an A+ BBB rating. The company is one of the few on this list that explicitly offers 24-hour AC repair for emergencies, covering both residential and commercial customers in Richardson. Because Baker Brothers also handles plumbing and electrical work under one roof, they are a practical call when an HVAC problem turns out to involve a related system — a tripped breaker, a clogged condensate drain line, or a water issue near the air handler. For after-hours failures in the middle of a Texas summer, their round-the-clock availability is a meaningful differentiator.

Best Richardson-Based Local Option
Rescue Air and Plumbing
Rescue Air and Plumbing is locally owned, locally operated, and based directly in Richardson, TX — not a regional chain dispatching from a distant office. The company has been BBB-accredited since February 2015 and handles residential HVAC repair, installation, and plumbing. For residents who prefer to work with a company that has a direct stake in the Richardson community rather than a broader metro presence, Rescue Air is the clearest choice on that basis.

Best for Duct Cleaning and Air Quality Work
Cool Experts AC
Cool Experts AC is located at 1300 E Arapaho Rd in Richardson and holds an A+ BBB rating. In addition to standard repair and seasonal maintenance, they specifically offer duct cleaning and air scrubbing — services that most pure HVAC companies either outsource or do not offer at all. If indoor air quality is a priority, or if your ductwork has not been cleaned in several years, Cool Experts is worth contacting for that scope of work.

For homeowners who want to schedule seasonal maintenance without a lengthy phone process, their direct booking option is a practical convenience.
How to Choose the Right HVAC Company for Your Situation
The right company depends on what you actually need:
- Replacing a system with a specific brand preference — Hammack (Lennox), AC Pros (Trane), or Houk (Trane, Carrier, or Lennox)
- Adding ductless mini-splits — Trotter Air Services
- Emergency repair at any hour — Baker Brothers
- Preferring a company headquartered in Richardson — Rescue Air and Plumbing
- Duct cleaning or air scrubbing — Cool Experts AC
- Seasonal AC tune-up with easy online scheduling — Varsity Zone HVAC
- Longest operational history in the market — Houk Air Conditioning (since 1962)
For routine maintenance calls, any company on this list with NATE-certified technicians is a reasonable starting point. NATE certification means the technician has passed an independent third-party exam — it is the closest thing to a standardized credential in the residential HVAC industry.
