Essential HVAC Maintenance Tips for Texas Summers

Texas summers put enormous strain on HVAC systems, with temperatures regularly exceeding 100°F for weeks at a time. In the DFW metro area, cooling systems may run 12-16 hours per day during peak summer months. Proper preparation and maintenance are essential to prevent costly breakdowns during the season when you need your system most.

Pre-Season Checklist

Before the heat arrives — ideally in March or April — schedule a professional inspection of your cooling system. A comprehensive tune-up should include checking refrigerant levels and pressures, cleaning condenser and evaporator coils, inspecting and tightening all electrical connections, testing capacitors and contactors, lubricating fan motors and bearings, verifying thermostat calibration, and clearing the condensate drain line.

Systems that enter summer without this maintenance are significantly more likely to fail on the hottest days, when repair companies are overwhelmed with emergency calls.

Filter Maintenance

During peak summer months, air filters should be checked every two to four weeks and replaced as needed. Clogged filters restrict airflow, forcing your system to work harder and consume more energy. A severely restricted filter can cause evaporator coils to freeze, leading to system shutdown and potential compressor damage.

We carry a full range of high-quality filters from Honeywell and other leading brands, including standard pleated filters, media air cleaners, and high-efficiency options for buildings with enhanced air quality requirements. Shop filters.

When to Call a Professional
