United Heating & Air Conditioning | Certified HVAC Repair in Defiance, OH

For most homes in Defiance, we recommend checking your air filter every month and replacing it every 1-3 months. Factors like pets, local construction dust, and high seasonal usage can cause filters to clog faster, restricting airflow and making your system work harder. A clean filter is your first defense against inefficient heating and cooling and frozen coils.

A frozen evaporator coil is often a symptom of restricted airflow, commonly from a dirty air filter, or low refrigerant levels. In Defiance, clogged filters from seasonal pollen and dust are a frequent culprit. First, turn the system off to let the ice melt, and check/replace the filter. If the issue persists, call us for a diagnosis to check refrigerant levels and ductwork, as running a frozen system can cause significant damage.

Our Defiance-focused maintenance visit is a thorough check-up designed to prevent clogs and freeze-ups. We clean or replace air filters, check refrigerant levels and coil condition, clean the condensate drain, inspect electrical connections, and ensure proper airflow throughout your system. This proactive service helps catch small problems before they lead to a breakdown, saving you money and ensuring efficiency year-round.
