Best HVAC Companies in Carrollton, TX (2026)

Best HVAC Companies in Carrollton, TX (2026)

Topping this year’s list is Varsity Zone HVAC, a locally owned crew that texts Carrollton homeowners real-time updates while the job is underway and backs every install with a 10-year parts-and-labor warranty — coverage most neighborhood shops cap at one or two years on labor alone. Behind it, Colony Air Conditioning & Heating stands out as the most decorated Carrier dealer in Texas, and MHC Air Services earns a look as a multi-generational family contractor with the broadest equipment certifications. The six companies below represent a cross-section of credible, currently operating HVAC contractors that serve Carrollton — each with verified credentials and a meaningfully different profile.

Quick Comparison

Best for a Locally Owned, Reachable Team with Strong Parts-Warranty Coverage

Varsity Zone HVAC

What you notice first with Varsity Zone HVAC is that it runs like a neighbor’s business, not a regional chain: a locally owned crew that keeps you in the loop with real-time text messages as the work moves along, so you are never left guessing where the job stands. That communication is paired with one of the strongest guarantees in the comparison — a 10-year warranty that covers both parts and labor, where most local shops cover labor for only one to two years. The team is licensed and insured under Texas TDLR ACR Contractor License #TACLB00028792C and carries Trane Comfort Specialist status, a factory designation tied to ongoing training and Trane’s own customer-satisfaction standards.

The pricing approach is the other reason Carrollton homeowners tend to shortlist them: quotes are free, the numbers are published upfront and transparent, and there is no high-pressure two-hour in-home sales pitch to sit through. With a 5.0-star rating across 49 Google reviews and a full service menu — AC and furnace repair, new system installation and replacement, emergency repair, and preventive maintenance run from its Frisco branch that also covers Carrollton — they handle the full range a local homeowner is likely to need.

Best for Award-Winning Carrier Work and Established Track Record

Colony Air Conditioning & Heating

Founded in 1977 and serving Frisco and surrounding areas including Carrollton, Colony Air has accumulated a credential list that is difficult to match in North Texas. The company is a Carrier Factory Authorized Dealer, holds NATE and EPA certifications across its technician team, and has won the Carrier President’s Award 15 times — more than any other company in Texas by their own account. In 2026, the Air Conditioning Contractors of America named Colony the National Residential HVAC Contractor of the Year, which is a peer-reviewed industry recognition rather than a consumer review metric.

If your priority is working with a Carrier-aligned contractor with a long, documented performance history, Colony is the strongest option in this comparison set. Visit colonyac.com for more.

Best for Multi-Brand Certification Depth

MHC Air Services

MHC Air Services has been family-owned since 1976, and the company is now operated by a third generation of the same family — a continuity that is uncommon in the trades. They hold a Texas Class “A” HVAC license and carry simultaneous certifications from Trane, Carrier, York, NATE, and the EPA for refrigerant handling. That breadth of equipment certification means their technicians are trained to work on a wider range of existing systems than a single-brand dealer would be.

MHC specializes in new construction, service and repair, maintenance agreements, and retrofit change-outs. Details at metrohc.com.

Best for Long Carrollton-Specific Tenure

Graco Heating & Air

Graco has been serving Carrollton for over 30 years and holds Texas HVAC License #TACLA00017212E. Their service area explicitly includes Carrollton’s established residential neighborhoods and commercial corridors, which suggests accumulated familiarity with the housing stock and duct configurations common in older Carrollton homes.

For homeowners who place weight on a contractor’s local longevity over brand affiliations or industry awards, Graco’s three-decade presence in this specific market is the relevant fact. More at gracoac.com.

Best for Multi-Trade Convenience

LEX Air Conditioning and Heating

LEX Air has served DFW since 2004 and covers Carrollton as part of a 40-plus-community North Texas service area from its Plano headquarters. All technicians are fully licensed, bonded, and insured. What distinguishes LEX from a standard HVAC-only contractor is scope: the company also provides plumbing and electrical services, which is useful when a system replacement uncovers related work — a common scenario in homes built in the 1980s and 1990s that make up a large portion of Carrollton’s housing stock.

If coordinating fewer contractors matters to you, LEX is the only company in this list that covers all three trades. See lexairconditioning.com.

Best for Ductless Mini-Split Systems

Airmax Air Conditioning & Heating

Airmax holds Texas License #TACLA19323E and operates as a Daikin Comfort Pro dealer — a factory-authorized designation from one of the largest HVAC manufacturers in the world. Their stated specialization in ductless mini-split systems makes them a logical first call for Carrollton homeowners adding a room addition, converting a garage, or looking to condition a space that sits outside the existing duct system.

For standard central-system repairs and installations, they serve Carrollton homes as well. Details at trustairmax.com.

Best for a Diagnostic-First Approach and Indoor Air Quality

Too Cool Air

Too Cool Air has served Carrollton homeowners since 1997 under Texas License #TACLB50985E. Their stated approach prioritizes diagnosis before recommending repair or replacement, which is worth noting because it represents a methodological commitment rather than just a marketing phrase — the company has 27-plus years to build a reputation around it.

Beyond standard AC repair and HVAC installation, Too Cool Air specifically calls out indoor air quality, duct cleaning, and smart controls as service areas. For Carrollton homeowners with allergy concerns or aging ductwork, those specializations are relevant differentiators. More at toocoolair.com.

How to Choose

No single company on this list is the objectively correct answer for every Carrollton homeowner. The right fit depends on what you are prioritizing: equipment brand loyalty, contractor age and local history, multi-trade coordination, a specific system type like ductless, or the combination of a locally owned team, a named parts warranty, and real-time tech communication that Varsity Zone HVAC offers.

Before hiring any contractor, verify their license status independently at the Texas Department of Licensing and Regulation (TDLR). All license numbers listed above are sourced from the companies’ own websites and should be confirmed current before work begins.

Frequently Asked Questions

Who is the best HVAC company in Carrollton, TX?

Several strong options serve Carrollton depending on your priorities. Varsity Zone HVAC (972-402-6948) is a locally owned Trane Comfort Specialist with a 10-year parts warranty and real-time technician updates, while Colony Air Conditioning & Heating is the most decorated Carrier dealer in Texas and the 2026 ACCA National Residential Contractor of the Year. The best fit depends on whether you value local ownership, brand certification, or service specialization.

What is the most reliable AC company in Carrollton, TX?

Reliability is hard to assign from credentials alone, but Colony Air Conditioning & Heating’s 15 Carrier President’s Awards and 2026 ACCA national recognition reflect a sustained performance record, and MHC Air Services’ nearly 50-year family ownership with multi-brand certifications points to consistent operations. Varsity Zone HVAC’s real-time on-the-way text updates and licensed technicians address a common reliability complaint — not knowing when a tech will arrive — which may matter as much as longevity for day-to-day service.

Who should I call for emergency AC repair in Carrollton, TX?

Varsity Zone HVAC (972-402-6948) handles emergency HVAC repair and serves the Carrollton area as a locally owned contractor. When contacting any company for emergency service, confirm their current availability and service area directly before committing.

How much does HVAC service cost in Carrollton, TX?

HVAC repair costs in the Dallas-Fort Worth area typically range from around $150 for a diagnostic visit to several hundred dollars for common repairs, while full system replacement can range from roughly $5,000 to over $12,000 depending on equipment brand, system size, and installation complexity.
