A-OK Air Conditioning & Heating: Licensed HVAC Repair Serving Richardson, TX 75081

It very well could be. The reversing valve is what switches your heat pump between heating and cooling modes. If it gets stuck or fails, the system can't produce heat properly. Our technicians in Richardson can diagnose this specific issue quickly. Often, a repair is possible, but if replacement is needed, we use high-quality parts to restore your home's warmth efficiently.

Yes, that's a classic sign of an evaporator coil freezing. This is a common issue in our Richardson climate and is usually caused by restricted airflow (like a dirty filter), low refrigerant levels, or a problem with the blower fan. It's important to turn the system off and call us. We'll thaw the coil safely, diagnose the underlying cause, and fix it to prevent damage and restore efficient cooling.

While all repairs are important, a complete system failure during extreme heat or cold is the most urgent for your comfort and safety. However, issues like a frozen coil or a malfunctioning reversing valve should be addressed promptly. Ignoring them can lead to more extensive (and expensive) damage, like compressor failure. We offer timely service to Richardson residents to solve these problems before they escalate.
