HVAC Repair Tomah WI | Call Performance Heating & Cooling Solutions

Tomah's cold, damp winters can cause ice to build up on your heat pump's outdoor coil, especially if the defrost cycle is faulty or airflow is restricted. If you see significant ice, turn the system to 'emergency heat' mode and call us. We'll safely thaw the unit, check the defrost controls, refrigerant levels, and airflow to prevent future freezing and protect your system.

In Tomah, with our seasonal dust and allergens, we recommend checking your standard 1-inch filter monthly and replacing it at least every 90 days. If you have pets or family members with allergies, consider changing it every 30-60 days. A clean filter prevents clogs that strain your blower motor, reduce efficiency, and can even lead to frozen coils in your heat pump.

We recommend bi-annual professional tune-ups: one in spring for your cooling system and one in fall for heating. Our Tomah-based maintenance includes cleaning coils, checking refrigerant levels, testing safety controls, inspecting electrical connections, and ensuring proper airflow. This proactive service catches small issues before they become major repairs, like a frozen heat pump or a system failure from a clogged filter.
