Before You Call Anyone, Know How to Protect Yourself
The moment your AC quits on a 100-degree McKinney afternoon, urgency works against you. Technicians who count on that urgency may recommend a compressor replacement when a capacitor swap would do the job. Two things protect you before a truck rolls up: ask for a written diagnostic quote before any work begins, and get a second opinion if the first quote tops $800 on a system under ten years old. Neither of these steps costs you much time, and both can save you hundreds.

Long-Established Local Names
Bill Joplin’s Air Conditioning & Heating (joplins.net) has been running service calls in McKinney and surrounding communities since 1978. They carry NATE certification, an A+ BBB rating, and have earned the Carrier President’s Award — a combination of credentials that is genuinely difficult to accumulate and harder to fake. For homeowners who treat contractor vetting the way they treat hiring a contractor for a roof, Joplin’s record speaks clearly.
Burnside Air Conditioning & Heating (burnsideac.com) has been operating under what they call the Gold Star Standard since 1958, giving them more than 65 years of continuous service in Collin County. A company that survives that long in one market is doing something right on the service side.
Newer but Well-Reviewed

Their A+ BBB rating and consistent five-star reviews across Google, Facebook, and Angi suggest they have built real customer loyalty in a market where word travels fast through neighborhood Facebook groups.
Airview AC (airviewac.com) has been voted a Nextdoor neighborhood favorite by local homeowners for four consecutive years. That kind of peer recognition from an app built around hyper-local trust is a meaningful signal, particularly for first-time homeowners who want a name they have seen their actual neighbors recommend.
Brandon’s Comfort Specialists (brandonsac.com) is McKinney-based and has been serving the Greater Dallas area for more than 20 years, holding an A+ BBB rating throughout. Their local base combined with broader service reach can be useful if you have rental properties or family across the metro.
How to Compare Your Options
Whichever names you start with, do not stop at one. Pull written diagnostic quotes from two or three licensed, NATE-certified local companies and lay them side by side before you authorize any repair. Compare the warranty each offers on parts and labor, the total price, and the company’s local track record and recent reviews. The right choice is the contractor that scores well across all of those for your specific repair — not simply the first one available. As with any contractor, confirm scope and pricing directly before work begins.
Common AC Failures in McKinney Homes
North Texas heat stress puts specific components at risk. Knowing the most common failures helps you evaluate a technician’s diagnosis.
- Capacitors and contactors are the single most frequent repair in this climate. Capacitors help motors start and run; they degrade faster in sustained high-heat conditions. A capacitor replacement typically runs $150–$350 parts and labor and should always be the first thing ruled out before any larger recommendation.
- Refrigerant leaks are common in systems over eight years old. The repair involves locating the leak, sealing it, and recharging the system. On older systems using R-22 refrigerant (see section below), this cost can escalate significantly.
- Dirty evaporator or condenser coils cause the system to work harder and freeze up. This is often a maintenance failure rather than a component failure — worth addressing before spending money on parts.
- Blower motor failure typically produces weak airflow or no airflow with the compressor still running. Motor replacements range from $300–$700 depending on the unit.
- Thermostat and control board issues can mimic serious system failures. Always confirm the thermostat is ruled out before accepting a diagnosis involving the air handler or compressor.
The Repair vs. Replace Decision
The $5,000 Rule
A widely used contractor-independent rule: multiply the repair cost by the age of the system in years. If that number exceeds $5,000, replacement typically makes more financial sense than repair. A $600 repair on a 6-year-old system ($3,600) is reasonable. A $700 repair on a 14-year-old system ($9,800) is a harder sell.
This rule is a starting point, not a verdict. Factor in the system’s overall condition, whether it has had multiple repairs in the past two years, and whether the rest of the unit is in good shape.
Age Thresholds to Know
Most central AC systems in North Texas operate reliably for 12–15 years. Beyond 15 years, major component failures become less predictable and more frequent. If your system is approaching or past that range and requires a repair costing more than 30–40 percent of a new system’s price, get a replacement quote from a second company before committing to the repair.
The R-22 Refrigerant Problem
Systems manufactured before approximately 2010 almost certainly use R-22 (Freon), which the EPA phased out of production. R-22 is no longer manufactured domestically and must be sourced from reclaimed supplies, which has pushed costs to $100–$150 per pound or higher. A system that needs two or three pounds of R-22 to address a leak — and still has an active leak — is rarely worth repairing. That money almost always belongs toward a new R-410A or R-32 system.
When Repair Is the Right Call
- The system is under 10 years old and this is its first significant failure
- The failed component is a capacitor, contactor, or thermostat
- The repair cost is under $500 on a system with otherwise clean maintenance history
- You have a planned replacement within 12–18 months and need to bridge the gap
When Replacement Makes More Sense
- The system is 15 or more years old
- It uses R-22 and has an active refrigerant leak
- You have spent more than $1,000 on repairs in the past two years
- The compressor has failed on a system over 10 years old (compressor replacement on an aging system often costs more than a new unit)
- Energy bills have risen significantly without an obvious explanation
Practical Steps When Your System Quits
- Check the thermostat batteries and settings first. It sounds obvious because it is, and it is also the cause of a meaningful percentage of “AC is broken” service calls.
- Check the circuit breaker. A tripped breaker on the air handler or condenser is a common cause of sudden shutdown.
- Check the condensate drain line. A clogged drain triggers a float switch that shuts the system off. Clear the clog and the system often restarts without a service call.
- If none of the above resolves it, call two companies from the list above for diagnostic quotes before authorizing any repair over $300.
- Ask each technician to explain exactly what failed, why it failed, and what the alternative options are. A technician who cannot or will not answer those questions clearly is a signal.
A Note on Seasonal Timing
McKinney HVAC companies get stretched thin in June, July, and August. If your system is aging and you know it, scheduling a pre-season inspection in March or April gives you time to make a replacement decision without deadline pressure. It also gives contractors time to order equipment, which matters during supply chain crunches that have hit the HVAC industry repeatedly in recent years.
Frequently Asked Questions
How much does AC repair cost in McKinney, TX?
Most AC repairs in McKinney fall between $150 and $800 depending on the failed component, with capacitor replacements on the low end and refrigerant leak repairs or blower motor replacements on the higher end. Compressor replacements can exceed $1,500 and often make replacement of the full system worth considering instead.
At what age should I replace my AC instead of repairing it?
A system 15 or more years old that requires a repair costing more than 30-40 percent of a new unit’s price is generally a replacement candidate rather than a repair one. The $5,000 rule — multiplying repair cost by system age — is a practical starting point: if that product exceeds $5,000, get a replacement quote before authorizing the repair.
Who should I call for AC repair in McKinney, TX?
Several well-established options serve McKinney directly, including Bill Joplin’s Air Conditioning and Heating (in business since 1978 with NATE certification and an A+ BBB rating), Burnside Air Conditioning and Heating (serving Collin County since 1958), Harris Air Services (family-owned since 2008 with strong peer reviews), Airview AC (a Nextdoor neighborhood favorite), and Brandon’s Comfort Specialists (McKinney-based with 20-plus years of service). Whichever you start with, request written quotes from two or three licensed, NATE-certified local companies and compare warranty, price, and reviews before authorizing the work.
What are signs my AC is about to fail?
Common warning signs include warm air blowing from vents with the system running, weak airflow, the system cycling on and off more frequently than normal, unusual sounds like grinding or clicking at startup, and a noticeable increase in electricity bills without a change in usage habits. Ice forming on the refrigerant lines or the air handler is also a sign that something is wrong and the system should be shut off and inspected.
