RTEC AIR: Certified HVAC Services Serving Houston, TX 77082

Yes, absolutely. A proper, professionally sized and installed system is the first defense against coil freeze-ups, which are common here due to our high humidity. An undersized or incorrectly installed unit can run constantly, causing the coil to drop below freezing and ice over. Our installation experts ensure your new system is perfectly matched to your home's layout and Houston's climate, promoting efficient operation and preventing this frustrating issue.

Faulty thermostat wiring is a frequent culprit for warm air in Houston homes, often caused by our heat and humidity affecting connections. Our technicians are skilled at diagnosing and repairing these wiring problems. We'll check the connections at your thermostat and air handler, identify any shorts, breaks, or corrosion, and make secure repairs to restore proper communication and cooling to your system quickly and reliably.

Our preventative maintenance service is tailored for Houston's specific challenges. To prevent evaporator coil freeze-ups, we thoroughly clean the coil and ensure proper airflow by checking and replacing dirty air filters—a major cause. We also verify refrigerant levels and check all electrical components, including thermostat connections, to catch small wiring issues before they leave you without cool air. Regular maintenance is the best way to ensure efficiency and prevent breakdowns during our hottest months.
