Commercial Furnace Repair and Maintenance in McKinney, TX

McKinney's commercial buildings are as varied as its homes. Historic storefronts and restaurants around the downtown square share the city with modern office parks, medical buildings, warehouses, and light industrial facilities. Each building type puts a different load on its heating unit. KMI A/C and Heating provides commercial furnace repair and maintenance in McKinney, TX, for all of them, with certified commercial HVAC technicians who adapt to the building in front of them.

Commercial Furnace Repair for Historic and Older McKinney Buildings

Older buildings bring heating challenges that new construction does not. Equipment may sit in a tight mechanical closet, an attic, or on a roof not designed for it. Gas piping may be old, and ductwork may leak or be undersized.

Signs Your Commercial Furnace Needs Repair:

• Rooms or dining areas that stay cold even when the furnace runs all day
• Weak airflow from some diffusers
• Dust, burning smells, or odd odors when the heating unit starts
• Pilot light problems or a burner flame that looks yellow
• Banging, rattling, or squealing noises
• Rising gas bills with no change in operating hours
• A furnace that cycles on and off or does not light

Our Commercial Furnace Repair Services for Older Buildings Include:

• Igniter, pilot assembly, and flame sensor repair
• Gas valve and gas connection inspection
• Blower motor, belt, and capacitor replacement
• Heat exchanger inspection and carbon monoxide testing
• Flue and venting inspection for blockages
• Thermostat upgrades and wiring repair
• Ductwork inspection to find leaks that waste heat

Why Older Buildings Need Careful Diagnosis:

• Leaky or undersized ducts can mimic a failing furnace
• Tight mechanical spaces make airflow and venting harder
• Older gas lines and connections deserve a careful safety check
• A proper diagnosis prevents wasted parts and money

Commercial Furnace Repair for Newer McKinney Buildings

Newer systems fail for different reasons. Standard-grade equipment, rushed installs, and heavy usage can all cause early problems.

Common Issues in Newer Buildings:

• Dirty or failed flame sensors
• Igniter and control board failures
• Blocked condensate lines on high-efficiency furnaces
• Thermostat or sensor errors
• Dust from nearby construction clogging filters and burners

Our Newer-Building Repair Services Include:

• Warranty-aware diagnosis and repair
• Wiring and control board repair
• Condensate drain and trap cleaning
• Airflow and static pressure testing

We tell you whether a failure is a part problem, an installation problem, or a maintenance problem.

Warehouse and Light Industrial Heating

McKinney's warehouses and shops often use unit heaters, rooftop heating units, and make-up air equipment. These systems face dust, tall ceilings, and open doors.

• Unit heater burner cleaning and ignition repair
• Gas piping and shutoff valve checks
• Fan and louver service for even heat distribution
• Thermostat placement and control tuning

Questions McKinney Business Owners Ask

Does my older building need a different type of maintenance?

The basics are the same, but we add venting, gas connection, and duct checks because older buildings are more likely to have leaks and tight equipment spaces.

Should I fix or replace a 15-year-old furnace?

It depends on the repair cost, the parts that have failed, and your energy bills. We give you the numbers so you can choose.
