Comfy Cool & Heating - Houston's Licensed HVAC Repair

An improperly sized system in our climate often shows up as high humidity indoors, constant on/off cycling, uneven temperatures between rooms, and surprisingly high energy bills. An oversized AC cools too quickly without removing enough moisture, while an undersized unit runs constantly and can't keep up. Our technicians perform precise load calculations to recommend the perfect size for your home's square footage, insulation, and layout during an installation or replacement.

Yes, a faulty reversing valve is a frequent culprit when a heat pump won't change modes. This crucial component directs refrigerant flow for heating or cooling. Over time, wear, electrical failure, or contaminants can cause it to stick. Our repair specialists can diagnose valve issues quickly. Often, regular maintenance can help prevent this problem by keeping the system clean and the refrigerant at proper levels, which is why we emphasize our maintenance plans for Houston's year-round HVAC use.

Our maintenance service is tailored for our local climate. We clean coils clogged by Houston pollen and humidity, check refrigerant levels critical for heat pump efficiency, inspect electrical components for corrosion from our moist air, and ensure the reversing valve and other key parts are operating correctly. This proactive care helps prevent the most common local failures, improves energy efficiency, and ensures your system is ready for both our scorching summers and occasional chilly winters.
