Theisen's Heating & Cooling | Experienced HVAC Services in New Lexington, OH

Yes, frozen evaporator coils are a frequent issue we see in our area. It's often a sign of restricted airflow, possibly from a dirty air filter or blocked return vents, or it could indicate a refrigerant leak. Both problems prevent your system from absorbing heat properly, causing the coil to ice over. Continuing to run a frozen system can cause serious damage. We recommend turning the system off to let it thaw and calling us for a professional diagnosis to prevent costly repairs down the line.

Short cycling is hard on your HVAC system and a common local complaint. It can be caused by an oversized unit, a malfunctioning thermostat, or—especially relevant here—a dirty or frozen evaporator coil. When the coil is blocked, the system overheats or overcools too quickly, triggering the safety shut-off. This constant stopping and starting wastes energy and wears out components prematurely. Our technicians can pinpoint the exact cause, whether it's a simple cleaning, a thermostat calibration, or a discussion about proper system sizing for your New Lexington home.

Proactive maintenance is the best defense. We recommend a seasonal tune-up, which includes a thorough cleaning of the evaporator and condenser coils, checking refrigerant levels, calibrating the thermostat, and inspecting all electrical components. For our New Lexington customers, we pay special attention to airflow and coil health during these visits, as these are the root of many local issues. This regular care not only prevents breakdowns but also keeps your system running efficiently, saving you money on energy bills and extending the life of your equipment.
