Jourdanton Hardware - Jourdanton's Certified HVAC Repair

For our local dust and pollen, we recommend a pleated filter with a MERV rating of 8-11. These trap more particles than basic fiberglass filters without overly restricting airflow, which is crucial for preventing evaporator coils from freezing. We carry a selection at the store and can help you find the right size and type for your specific HVAC unit.

A frozen coil is often a symptom of restricted airflow or low refrigerant. Before you call for service, check and replace a clogged air filter—we have those in stock. If the filter is clean, you may need a professional to check for leaks. We carry refrigerant leak detectors and coil cleaning solutions that can help with maintenance, but a persistent freeze-up usually requires a certified technician's diagnosis.

Yes, we do. Keeping the outdoor condenser clean is vital for efficiency. We stock condenser coil cleaners, fin combs to straighten bent fins, and hose attachments for safe rinsing. Stop by, and we can show you the simple tools and non-acidic cleaners that are safe for your unit, helping you maintain proper airflow and prevent strain on the entire system.
