How to Prepare Your HVAC System for a Texas Summer

Texas summers are not just hot — they are a legitimate test of your home HVAC system. In Hood County, temperatures regularly exceed 100F for weeks at a time. The difference between a system that holds up all summer and one that fails on the hottest day often comes down to preparation.

1. Schedule a Professional Tune-Up in April or May

A professional HVAC tune-up is the single most important thing you can do before summer. A licensed technician will check refrigerant levels, clean coils, test capacitors and contactors, inspect the blower motor, and check the condensate drain. Catching a failing part in April costs a fraction of an emergency call in July when every HVAC company in Hood County is booked solid.

2. Replace Your Air Filter

In Texas, standard 1-inch filters should be changed every 4-6 weeks during heavy use seasons. A clogged filter restricts airflow, forces your system to work harder, and increases energy consumption. Stock up on filters at the beginning of summer so you are never tempted to skip a change.

3. Clean Around Your Outdoor Unit

Clear grass, weeds, or debris within 2 feet of your condenser unit. Gently rinse it with a garden hose from the inside out. Your condenser needs unrestricted airflow to release heat efficiently — a blocked condenser forces your system to work much harder.

4. Install a Smart Thermostat

A smart thermostat lets you set higher temperatures when you are away and cool down before you return. This reduces how hard your system works during peak heat hours and can reduce cooling costs by 10-15%. Texas HVACR Pros installs and programs smart thermostats throughout Granbury and Hood County.

5. Check Your Condensate Drain Line

Your AC removes humidity from the air and that moisture drains out through the condensate drain line. In Texas humidity, algae and mold can grow in this line and cause clogs leading to water damage and system shutdowns. Flush the drain line with distilled white vinegar every few months.
