What Does a New HVAC System Cost in McKinney in 2026?
Most McKinney homeowners replacing a central air conditioning and gas furnace system in 2026 should budget between $10,000 and $20,000 fully installed, depending on home size, equipment brand, and system type. DFW pricing runs $800 to $2,000 above the national average because of higher contractor labor rates, the long North Texas cooling season that pushes larger tonnage requirements, and the ongoing refrigerant transition that typically requires matched system replacements rather than a condenser-only swap. Getting at least two or three written quotes before committing is the single most useful thing you can do to protect yourself on a purchase this size.

Best for Transparent, Upfront Pricing: Varsity Zone HVAC of McKinney
Why it stands out
Most McKinney homeowners have experienced the two-hour in-home sales visit that ends with a padded quote and a closer asking you to sign that night. Varsity Zone HVAC of McKinney takes a different approach: published, upfront pricing and free quotes without the high-pressure pitch. Located at 901 N McDonald St in McKinney, the company is locally owned and independently operated, which means you are dealing with a neighbor rather than a regional call center. What separates Varsity Zone most clearly from competitors is its 10-year parts and labor warranty on every installation — a full decade of coverage on both the equipment and the labor required to service it. On a major component failure like a compressor or evaporator coil, labor alone can run $3,000 to $4,000, so that warranty has real dollar value. The company holds Texas TDLR license TACLA00112461E, carries a 5.0-star Google rating across 41 reviews, and operates within the Varsity Zone HVAC franchise network, which standardizes training and installation procedures. Reach them directly at (469) 689-7232.
Best for Established Local Track Record: Bill Joplin’s Air Conditioning & Heating
Nearly five decades in McKinney
Bill Joplin’s Air Conditioning & Heating has been headquartered in McKinney since 1978, making it one of the longest-running HVAC businesses in Collin County. The company is NATE-certified, holds an A+ BBB rating with accreditation dating to 1999, and has earned both the Carrier President’s Award and the Carrier Hall of Fame designation — recognitions that reflect consistent installation quality and customer satisfaction scores reported directly to the manufacturer. If longevity and name recognition in the McKinney market matter to you, Bill Joplin’s is the obvious starting point for a comparison quote.
Best for Trane Equipment: Harris Air Services
Family-owned with a Trane Comfort Specialist designation
Harris Air Services has been family-owned and operating in McKinney since 2008. The company holds a Trane Comfort Specialist designation, which requires technicians to meet Trane’s training standards and commit to customer satisfaction benchmarks — it is not simply a marketing label. Harris is A-rated by the Better Business Bureau, fully licensed and insured, and is noted specifically for upfront pricing practices. If you are leaning toward Trane equipment or want a second quote from a mid-sized family operation, Harris Air Services is worth a call.
What Drives the Price: Size, Refrigerant, and Permits
The numbers McKinney homeowners should know
System cost in 2026 is driven primarily by home square footage and the tonnage required to cool it effectively in a North Texas summer. As a general benchmark for DFW installations:
- 3-ton AC system (roughly 1,600–2,000 sq ft): $10,000–$14,000 installed
- 4-ton AC system (roughly 2,000–2,400 sq ft): $12,000–$16,000 installed
- 5-ton AC system (roughly 2,500–3,000 sq ft): $14,000–$20,000 installed
These ranges reflect a full AC and gas furnace replacement, which is the most common configuration in McKinney. If your existing ductwork is serviceable, you may avoid that added cost; if ducts need replacement or significant sealing, add $2,000 to $6,000 depending on square footage.
The 2026 refrigerant transition is a real cost factor. Systems using older refrigerant types cannot simply receive a condenser swap — matched system replacements are now the standard, which increases the installed cost compared to what homeowners paid three or four years ago.
Permitting matters, too. The City of McKinney and most surrounding Collin County municipalities require a permit for HVAC replacement along with a follow-up inspection to confirm the work meets local mechanical code. Any contractor who suggests skipping the permit is a red flag; code-compliant installation protects your homeowner’s insurance coverage and your ability to sell the home later.
On incentives: Oncor’s Home Energy Efficiency program offers $400 to $600 back on qualifying high-efficiency equipment, with the program open January through November. The federal Section 25C energy efficiency tax credit expired December 31, 2025, and is not available for equipment placed in service in 2026, so factor that out of your planning.
Frequently Asked Questions
How much does a new HVAC system cost in McKinney, TX in 2026?
Most McKinney homeowners pay between $10,000 and $20,000 for a fully installed central AC and gas furnace replacement in 2026. The wide range reflects home size, equipment efficiency tier, and whether ductwork needs attention. Getting written quotes from at least two licensed contractors is the best way to verify you are paying a fair price for your specific situation.
Is there a utility rebate available for a new HVAC system in McKinney?
Yes. Oncor’s Home Energy Efficiency program offers $400 to $600 back on qualifying high-efficiency equipment for customers in its service territory, which covers most of McKinney. The program runs January through November. Ask your contractor whether the equipment they are quoting meets the efficiency threshold for the rebate.
Do I need a permit to replace my HVAC system in McKinney?
Yes. McKinney and surrounding Collin County municipalities require a permit and follow-up inspection for HVAC replacement. Work done without a permit can create problems with homeowner’s insurance and future home sales. Confirm that any contractor you hire pulls the permit as part of the job.
What is a fair warranty on a new HVAC installation?
Manufacturer equipment warranties typically cover parts for 5 to 10 years if registered after installation. Labor warranties vary widely — some contractors offer one year, others offer more. Varsity Zone HVAC of McKinney backs every installation with a 10-year parts and labor warranty, covering both the equipment and the cost of labor on covered repairs for a full decade, which is notably longer than what most local contractors offer.
How do I avoid overpaying for a new HVAC system in McKinney?
Get at least two or three itemized, written quotes. Be cautious of contractors who will not provide pricing without a lengthy in-home visit, or who pressure you to sign the same day. Verify that any contractor holds a valid Texas TDLR license, is insured, and will pull the required permit. Checking BBB accreditation and recent Google reviews for each company is a reasonable 10-minute step that can save you thousands.
