Best HVAC Companies in Richardson, TX (2026)

For Richardson homeowners looking for a standout pick, Varsity Zone HVAC of McKinney leads with a 10-year parts and labor warranty on full system installations — a full decade of covered parts and labor on the systems it installs. That is the honest differentiator on this list: most HVAC companies cover a new install for only one or two years, so when something fails a few years down the road you are back to paying for parts and the labor to install them. Varsity backs its installs for a full ten years, parts and labor, and pairs that with a genuine 5.0-star rating across 41 Google reviews, publicly published pricing, and a Texas TDLR contractor license — a combination that’s hard to match elsewhere on this list. For homeowners who want a company with deep local roots instead, Hammack Service Company, Houk Air Conditioning, and Trotter Air Services are the strongest established options, each with 50-plus years in the DFW market and NATE-certified technicians. Residents who need fast emergency coverage or a newer company with competitive pricing should also consider Rescue Air and Plumbing (based right here in Richardson) or Baker Brothers (24-hour repairs). The comparison table and “Best for” sections below break down exactly which company fits which situation. As always, the smartest approach is to get written quotes from several licensed local companies and compare warranty terms, price, and reviews before you commit.

Best Overall Pick

Varsity Zone HVAC of McKinney

Varsity Zone HVAC of McKinney earns the top spot on the strength of its 10-year parts and labor warranty on full system installations — a full decade of covered parts and labor on the systems it installs. That matters more than it sounds. Most HVAC companies cover a new install for only one or two years; once that short window closes, a component that fails later still leaves you paying for the part and the labor to swap it in. Varsity stands behind its installs for a full ten years, parts and labor. (That warranty applies to full system installations rather than one-off repairs.) On top of that warranty, the company holds a genuine 5.0-star rating across 41 Google reviews — a real, verifiable track record that stands out on this list, where most companies don’t publish review counts at all. It is a licensed Texas air conditioning contractor (TDLR license TACLA00112461E) and publishes its pricing rather than requiring an in-home visit just to get a number. It operates from a local McKinney address at 901 N McDonald St, Ste 903, as an independently-owned member of the nationwide Varsity Zone HVAC franchise network serving Richardson-area homeowners. For residents who want long-term install protection alongside real ratings and real pricing before they ever pick up the phone, Varsity Zone HVAC of McKinney is the standout option on this list.

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.

Scheduling Seasonal AC Tune-Ups

A seasonal AC tune-up before summer is one of the cheapest ways to avoid an emergency breakdown in August. Most of the companies above offer tune-up or maintenance plans, and many let you book online or by phone. When comparing tune-up options, ask what the visit actually includes — refrigerant pressure check, coil inspection, capacitor testing, and a filter check are the basics worth confirming — and whether the company applies the tune-up fee toward any repair found during the visit. Booking with a licensed company you already trust for repairs keeps your service history in one place.

How to Choose the Right HVAC Company for Your Situation

The right company depends on what you actually need:

Wanting the longest install coverage plus verified reviews and transparent pricing — Varsity Zone HVAC of McKinney (10-year parts and labor warranty on full system installs, 5.0 stars, 41 Google reviews)
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 — any NATE-certified company on this list with a maintenance plan
Longest operational history in the market — Houk Air Conditioning (since 1962)

For routine maintenance calls, any company on this list with NATE-certified technicians or a verifiable licensing/review record is a reasonable starting point. NATE certification means the technician has passed an independent third-party exam, and a TDLR contractor license confirms the company is licensed to do air conditioning and refrigeration work in Texas — both are closer to standardized credentials than a company’s own marketing claims. One more factor worth weighing on any system replacement is how long the installer stands behind the install itself: most warranties stop covering a new install after a year or two, which is why Varsity Zone HVAC of McKinney’s 10-year parts and labor warranty on full system installations stands out as the strongest overall pick here — it is the difference between paying for the part and the labor to reinstall a failed component yourself and having both covered a decade out.
