AC was freezing up every couple of days. Previous company kept adding refrigerant. Williams found the actual leak at the evaporator coil, repaired it properly, and it has held all season.Nathan B. · Harker Heights, TX

Old furnace had a cracked heat exchanger. They showed me the crack with a camera instead of just telling me. Made the replacement decision easy and they installed it the next day.Yolanda G. · Harker Heights, TX

Questions
HVAC Repair & Service FAQs — Harker Heights, TX
What is included in an HVAC service call in Harker Heights?
A technician inspects and tests the full system: electrical components, refrigerant charge, airflow, controls, the condensate system, and the ductwork where accessible. You get a written finding with the actual readings, not just a verdict.
Why is my house humid even though the AC is running?
Usually an oversized system that short cycles, or a blower running too fast for the coil. Both cool the air without giving it enough contact time to condense moisture. Correcting fan speed often fixes it without new equipment.
Can you fix ductwork in my attic?
Yes. Disconnected boots, crushed flex, leaking plenums, and undersized returns are extremely common in Harker Heights homes and they cause more comfort complaints than equipment failures do.
Do you service commercial rooftop units?
We handle light commercial rooftop and packaged equipment for small offices, retail spaces, and restaurants in the Harker Heights area alongside our residential work. Call (833) 435-6611 to discuss the specifics.
How do I know if the problem is the thermostat or the system?
A technician can isolate it in minutes by jumping the low-voltage terminals at the air handler. If the system responds directly but not to the thermostat, the thermostat or its wiring is the fault.
What is static pressure and why does it matter?
It is the resistance the blower has to push against, similar to blood pressure for a duct system. High static pressure kills airflow, shortens motor life, and causes both freezing coils in summer and short cycling in winter. Most companies never measure it. We do.
How long does a new AC installation take?
A standard residential changeout in Harker Heights is typically one day. Jobs involving ductwork modifications, attic access issues, or electrical upgrades can run into a second day. We give you the realistic timeline before scheduling.
How fast can you get to my home in Harker Heights?
Most standard appointments in Harker Heights are scheduled same day or next day, and emergency calls are dispatched as soon as a technician is free. When you call (833) 435-6611 the dispatcher will give you a realistic arrival window rather than an optimistic one, and you will get a call ahead before the technician arrives.
