A Action Heating & AC - Gaithersburg's Experienced HVAC Repair

Yes, that's a common issue here. The reversing valve is critical for switching between heating and cooling. Our technicians perform a detailed diagnosis to confirm the valve is the culprit. We then expertly repair or replace the valve, ensuring it's properly calibrated for our local climate to restore full, efficient operation of your heat pump.

Given local allergens and seasonal humidity, we recommend a layered approach. We start with a professional duct cleaning to remove accumulated dust and debris. Then, we can install high-efficiency air filters or a whole-home air purification system, like a UV light, to actively neutralize mold spores, bacteria, and viruses, creating a cleaner, healthier indoor environment.

Absolutely. Our preventative maintenance plans are designed for Gaithersburg homes. We perform bi-annual tune-ups that include checking refrigerant levels, testing the reversing valve operation, cleaning coils, and inspecting air filters and ductwork. This proactive care helps prevent breakdowns, improves efficiency, and maintains better air quality, saving you money and hassle in the long run.
