A1 Mechanical Service | Trusted HVAC Repair in Coweta, OK

That's a classic sign of an evaporator coil freeze-up, a common issue in our area often caused by restricted airflow or low refrigerant. First, turn your system off to let the ice melt completely. Continuing to run it can cause serious damage. Our technicians at A1 Mechanical Service will diagnose the root cause—whether it's a dirty filter, blocked vents, or a refrigerant leak—and perform the precise repair needed to restore efficient cooling and prevent future freeze-ups.

Thermostat malfunctions are a frequent headache for local homeowners. Short cycling or failure to start can stem from wiring issues, dead batteries, dust buildup inside the unit, or the thermostat being in a poor location (like in direct sunlight or a drafty hallway). Our expert team will test your thermostat's calibration, check the wiring, and assess its placement. We can often fix the issue on the spot or recommend a reliable replacement to restore consistent and accurate control of your home's temperature.

Great question! Proactive maintenance is key. We recommend changing your air filter every 1-3 months to ensure proper airflow, which is a major factor in preventing coils from freezing. Also, keep all supply and return vents unobstructed by furniture or curtains. Scheduling an annual professional tune-up with A1 Mechanical Service is the best defense. We'll clean the coils, check refrigerant levels, calibrate your thermostat, and catch small issues before they lead to a breakdown, saving you discomfort and money in the long run.
