J's Air & Heating Services - Dallas's Expert HVAC Services

Yes, a faulty reversing valve is a common culprit for this issue in Dallas, especially with our frequent temperature swings that cause extra wear. Our technicians perform a thorough diagnostic to confirm the valve is the problem. If repair isn't viable, we'll expertly replace the valve, ensuring your heat pump can properly reverse refrigerant flow to efficiently both heat and cool your home, saving you from needing separate systems.

Due to significant dust and pollen in our area, we generally recommend checking your filter monthly and replacing standard 1-inch filters every 30-60 days. For homes with pets or allergy sufferers, monthly changes are best. We can assess your specific system during a maintenance visit and recommend the optimal filter type and schedule to prevent clogs that strain your HVAC system and reduce indoor air quality.

Our Dallas-focused maintenance service is designed to catch problems like early valve wear or excessive dust buildup before they cause a breakdown. We thoroughly clean system components, check refrigerant levels, test electrical connections, lubricate moving parts, and calibrate your thermostat. Most importantly, we inspect the heat pump's reversing valve operation and check your filter, providing a detailed report on your system's health to ensure reliable, efficient performance through our hot summers and cool winters.
