Expert HVAC Repair in Texarkana, TX 75503 - Custom Aire

It very well could be. A stuck or failing reversing valve is a common issue in our Texarkana climate, as the component cycles frequently between heating and cooling modes. This prevents the system from properly reversing refrigerant flow to provide heat. Our technicians can perform a detailed diagnosis to confirm if it's the valve, another electrical issue, or a refrigerant problem, and provide a clear repair plan to get your warmth back.

We never guess on size. Our process starts with a Manual J load calculation, which factors in your home's square footage, insulation, window types, sun exposure, and even local Texarkana weather data. This precise math ensures we recommend a system with the exact capacity needed—no more, no less. A properly sized unit runs efficiently, maintains consistent comfort, and avoids the short-cycling and high humidity issues common with oversized systems.

In many cases, a skilled technician can repair or replace just the reversing valve. However, if the valve has failed due to age or significant wear, and the system is older, a full replacement might be the more reliable and cost-effective long-term solution. We'll provide an honest assessment, explaining the condition of your entire system and the pros and cons of repair versus replacement, so you can make the best decision for your home and budget.
