Seasonal HVAC Maintenance Checklist for Texas Homes

Before the intense Texas summer heat arrives, schedule professional AC maintenance. This should include refrigerant level checks, coil cleaning, electrical connection inspection, and thermostat calibration. Replace your air filter and clear debris from around your outdoor unit. Test your system by running it for 15-20 minutes to ensure it cools properly before you really need it.

During peak cooling season, check your air filter monthly and replace as needed. Keep your outdoor unit clear of vegetation with at least 2 feet of clearance. Clean leaves and debris from the unit regularly. If you notice reduced cooling, higher bills, or unusual sounds, schedule service promptly. Running a struggling system can cause further damage and higher costs.

Before the first cold snap, schedule heating system maintenance. Technicians should inspect the heat exchanger for cracks, test safety controls, check gas connections, and clean burners. Replace your air filter and test your thermostat in heating mode. For heat pumps, ensure the defrost cycle is working properly for those occasional freezing Boerne mornings.

Continue monthly filter checks through heating season. Keep outdoor heat pump units clear of ice and debris. If you have a gas furnace, ensure carbon monoxide detectors are working. During extended freezes, keep your thermostat above 55 degrees even when away to prevent pipe freezing. Your HVAC system works harder during temperature extremes, so address any issues promptly.

Call a professional if you notice uneven temperatures between rooms, unusual odors when the system runs, excessive dust or humidity, strange sounds, or significantly higher energy bills. For systems over 10 years old, consider a replacement evaluation. Modern high-efficiency systems can reduce energy costs by 20-40% compared to older units.
