AC repair in McKinney
By the HeatAndAirCost editors · Last updated October 5, 2026 · How we research prices
Short answer
A typical AC repair in McKinney costs $150 to $650, close to the national average of $350, plus a $75 to $200 diagnostic fee. NOAA normals list about 2,498 heating degree days a year alongside a long, hot summer, a reminder that a Collin County system works through genuine cold spells as well as heat.[1]
What McKinney homeowners call about most
Between hot summers and the occasional hard freeze, these three issues cover most McKinney service calls.
- A high-pitched squeal from the outdoor unit. A squeal is often a fan motor bearing or a belt-driven part wearing out, and it tends to get worse rather than better on its own. Catching it early is usually cheaper than waiting for the part to fail completely.
- Ice forming on the refrigerant line outside. Ice on the line typically points to restricted airflow or a low refrigerant charge, not a sign the system is simply working too hard in the heat. Running the system with ice on the line can damage the compressor, so it is worth turning it off and calling for service.
- Thermostat goes blank or stops responding. This is usually a power or wiring issue at the thermostat rather than a failure of the outdoor unit. Checking the breaker and any batteries first rules out the simplest cause.
Texas TDLR licensing for McKinney HVAC work
As in the rest of Texas, HVAC licensing in McKinney runs through TDLR at the state level rather than through the city. A company installing, repairing, or maintaining AC and refrigeration systems should hold, or employ someone who holds, the TDLR Air Conditioning and Refrigeration Contractor (ACR) license.
Before hiring, verify the license number on TDLR's website and confirm the contractor pulls a permit for a full system replacement.[3]
Collin County's hot summers and cold nights in McKinney
McKinney shares its NOAA station, at McKinney Municipal Airport, with nearby Frisco: a normal summer high near 94°F, about 97 days a year at 90°F or hotter, and roughly 2,498 heating degree days alongside 2,531 cooling degree days. That near-even split between heating and cooling demand means a McKinney system has real work to do on both sides of the year.
Collin County's growth has brought in a large share of newer homes, and many McKinney systems are younger than the Texas average as a result. Heat still stresses the usual parts, capacitors, contactors and fan motors, regardless of a system's age, and McKinney's cold nights, roughly 48 a year at or below freezing by NOAA's normal, can expose a weak ignition component or safety switch on equipment that otherwise ran fine all summer.
Replacing the filter and checking that the thermostat is set correctly are the two free steps before calling for service. If a newer system is already struggling to keep up on a 95°F afternoon, that often points to a refrigerant or airflow problem rather than a sign the equipment itself is failing early.

How hard McKinney's climate works an HVAC system
Degree days count how far each day's average temperature sits from 65°F. Both seasons count here: cooling degree days run about 1.0 times heating degree days, so the heating side and the cooling side each put in a real season. At this station the normal summer high is 94°F (June through August) and the normal winter low is 36°F (December through February).

What electricity and natural gas cost in Texas
Homes in Texas paid an average of 15.47 cents per kilowatt-hour in 2025, 11% below the U.S. average of 17.30 cents. Natural gas delivered to homes averaged $17.98 per thousand cubic feet in 2024, 24% above the U.S. figure of $14.50. An air conditioner runs entirely on electricity, so the state rate sets the price of every extra hour of cooling. If a summer bill jumps without a matching heat wave, our high electric bill from AC guide lists the checks to run first.

How McKinney homes heat, and how old they are
Utility gas heats 53% of occupied homes in McKinney and electricity heats 45%, so a gas furnace is the most common setup. The usual gas-furnace failures are covered in furnace not turning on. Half of the city's housing units were built in 2007 or earlier, and 7.8% predate 1980, while 40% went up in 2010 or later. Our HVAC lifespan guide explains how long furnaces, air conditioners and heat pumps typically last.

Plumbing, heating and air-conditioning businesses in Collin County
The Census Bureau counted 264 plumbing, heating and air-conditioning contractor establishments in Collin County in 2023, with 2,939 employees between them. The industry code (NAICS 238220) includes plumbers and counts business locations, not licenses, so treat it as an upper bound on HVAC firms. It names no company; check any contractor's license before you hire.

What HVAC technicians earn in the Dallas-Fort Worth-Arlington, TX area
The median heating, air-conditioning and refrigeration mechanic in the Dallas-Fort Worth-Arlington, TX metro area earned $59,560 a year in May 2025, 2% below the national median of $61,010. An invoice adds parts, travel, overhead and margin to that wage, so read it as context for labor rates, not a price; our service call cost guide breaks a bill down.

Is this covered by a home warranty?
A home warranty is an annual service contract that pays to repair or replace covered home systems and appliances when they fail from normal use, in exchange for a monthly premium and a fixed service fee per visit. It does not cover a failure that has already happened or a fault that existed before the plan started, so it only helps if it is in place before the breakdown.

McKinney AC repair FAQs
How much does AC repair run in McKinney?
Most repairs fall between $150 and $650, averaging around $350 nationally, with a separate $75 to $200 diagnostic fee. A capacitor costs about $250 to $400 installed, a fan motor runs higher, and a full compressor replacement typically lands between $1,800 and $2,800. These numbers are researched national figures for 2026, not a bid from a McKinney contractor.
Does McKinney get cold enough to damage AC or heat pump equipment?
NOAA's normal counts about 48 nights a year at or below 32°F in the McKinney area, enough cold for a furnace or heat pump's ignition system to be tested every winter. A unit that ran fine all summer can still fail on the season's first hard freeze.
Why do new McKinney neighborhoods sometimes have uneven cooling?
Newer subdivisions still rely on ductwork that has to be balanced correctly for every room, and a system sized for the whole house can still leave one bedroom or bonus room warmer than the rest. A technician can check airflow room by room to find the cause.
Is a Texas license required for AC companies in McKinney?
Yes. TDLR's Air Conditioning and Refrigeration Contractor (ACR) license covers companies that install, repair, or maintain AC and refrigeration equipment across Texas, including McKinney. Verify the license number on TDLR's site before hiring.
What is the $5,000 rule for HVAC?
This shortcut multiplies a unit's age by the repair estimate and checks the result against $5,000. A 5-year-old unit and a $300 repair multiply out to 1,500, solidly favoring repair. An 11-year-old unit and a $1,150 repair multiply out to 12,650, a total that tips toward a new system. Check the $5,000 rule guide for the complete picture.
