All Colston Services - Oklahoma City's Experienced HVAC Services

Many thermostat issues in OKC homes stem from faulty wiring or unstable power at the control board. Our electric inspection verifies the voltage, checks for shorts or loose connections at the thermostat wiring, and ensures your HVAC system has a proper, dedicated circuit. This foundational check often resolves erratic thermostat behavior and prevents misdiagnosis, saving you time and money on unnecessary HVAC part replacements.

Absolutely. In Oklahoma's varying seasons, overgrown grass, weeds, and debris can quickly obstruct the outdoor unit (condenser) of your heat pump. Blocked airflow is a leading cause of inefficiency and can contribute to issues like the reversing valve struggling to switch between heating and cooling modes. Our regular lawn care includes trimming and clearing a 2-foot perimeter around your unit, ensuring optimal airflow and helping your system run smoothly.

Not always. While a faulty reversing valve is a common culprit, the issue could also be electrical. Before assuming a major repair, our technicians first perform a detailed electrical inspection. We check the thermostat signals, the reversing valve solenoid, and associated relays for power. Often, the problem is a tripped breaker, a blown fuse, or a faulty connection—issues we can fix quickly, potentially avoiding a full valve replacement.
