OA Central Air - Garland's Experienced HVAC Services

Our maintenance service is designed to keep your system running efficiently through Garland's hot summers and cool winters. We perform a comprehensive check, including cleaning coils, checking refrigerant levels, inspecting electrical components, and calibrating your thermostat. For homes with heat pumps, we pay special attention to the reversing valve and defrost cycle. This proactive care helps prevent unexpected breakdowns and can extend the life of your system.

Yes, this is a common issue we address for Garland residents. Connectivity problems often stem from incorrect wiring at the HVAC unit, a compatibility issue, or a need for a common wire (C-wire) that your thermostat may require. Our technicians will diagnose the root cause at your thermostat and at the air handler or furnace, ensuring proper installation and setup so you can reliably control your home's temperature from your device.

As a rule of thumb, if your system is over 10-15 years old, requires frequent repairs, or your energy bills are steadily climbing, a replacement may be more cost-effective. We consider factors specific to your Garland home, like insulation levels and ductwork condition. We provide honest assessments, and if a replacement is the best path, we guide you through efficient models that qualify for rebates and can better handle our local climate.
