Heating and Furnace Repair in McKinney, TX

Most McKinney homes were built after 2000, and many of their original furnaces and heat pumps are now 15 to 25 years old. When the heat quits, here’s what to check, what to do if you smell gas, and how McKinney’s permit rules apply.

No heat in McKinney? Check these before you call

• Furnace switch and breaker. The switch near the furnace looks like a light switch and is easy to bump off.
• Furnace door. Most furnaces won’t run if the front panel isn’t fully closed.
• Gas smell. If you smell gas, leave the house first, then call 911 and your gas utility from outside. Don’t touch the thermostat or light switches on the way out.
• Power. Even a gas furnace needs electricity for its blower and controls. Depending on your address, McKinney gets its electricity from Oncor or CoServ; your bill tells you which. If the whole house is dark, report it to Oncor at 888-313-4747 or CoServ at 800-274-4014 before you call an HVAC company. Some systems wait before restarting after power returns, so give it a little time.
• Thermostat. Set to Heat and above the room temperature.
• Filter. A clogged filter can overheat a furnace and trip its limit switch.

Still cold? Call 972-423-0012, 24/7.

McKinney homes and what their age means for your system

McKinney’s growth came late and fast. The Census puts the median McKinney home at 2007, and about 7 in 10 homes are single-family detached houses. At the same time, McKinney has a historic downtown with homes far older than the rest of the city.

The Census counts about 77,617 homes in McKinney. Here’s how they break down by decade built:

The house’s age doesn’t tell you the system’s age. The data plate on the outdoor unit does, and it’s the first thing we read.

McKinney’s inspection checklist for new homes shows what the City looks for in an HVAC installation: all equipment installed, including primary and secondary condensate drains, and an access walkway, working platform and lighting at the unit. A clogged primary drain on an attic unit is a common repair call; the secondary drain is there to catch the overflow, and water from it is a warning sign.

McKinney permits for HVAC work

• McKinney’s inspection checklist covers the installed equipment, primary and secondary drains, and the access walkway, working platform and lighting at the unit.
• The City of McKinney lists mechanical work (heating, cooling and ventilation) among home repairs that require a permit. It’s applied for through the City’s CSS portal as a Residential Stand-Alone Mechanical permit.
• The City lists minor repairs, including routine filter replacement, as work that doesn’t need a permit.

Dallas Heating and Air Conditioning is registered with the City of McKinney as a mechanical contractor. For a replacement, we pull the permit and schedule the inspection.

In the older homes around historic downtown McKinney, ducts and equipment can sit in tight or unusual spots. In the newer neighborhoods, it’s usually an attic furnace or air handler. We bring what we need for both, and tell you up front what we find.

Refrigerant and efficiency rules that affect your decision

R-22. The EPA ended the manufacture of new R-22 equipment in 2010 and the production and import of R-22 itself on January 1, 2020. An R-22 system can keep running, but it can only be recharged with recovered or reclaimed R-22. A large leak on an R-22 unit is often the point where replacement makes more sense than repair.

SEER2. Since January 1, 2023, Department of Energy rules require new split-system central air conditioners installed in the Southeast region, which includes Texas, to meet at least 14.3 SEER2 under 45,000 Btu/h and 13.8 SEER2 at 45,000 Btu/h and up. New split heat pumps nationwide must meet 14.3 SEER2. See SEER vs. SEER2.

Heat pumps. A heat pump is also your air conditioner, so the same rules apply, and a failed heat pump can take out heating and cooling at once. See heat pump repair.
