Dallas summers are no ordinary heat. Temperatures in Dallas County regularly climb past 100°F for weeks at a time, putting residential and commercial AC systems under continuous stress. Neighborhoods like Lake Highlands, Lakewood, Oak Cliff, East Dallas, and Uptown all face the same grueling demand on cooling equipment from June through September. Skipping routine maintenance in this climate can mean shortened equipment life, higher energy bills, and a breakdown on the hottest day of the year.
A-Thompson Refrigeration, Air Conditioning & Heating, Inc. has been helping Dallas-area property owners stay ahead of that risk for more than five decades.

What Does AC Maintenance Include in Dallas?
A professional tune-up visit covers the key components that keep your system running efficiently in extreme Texas heat. Air conditioning maintenance typically goes well beyond a simple filter swap. A licensed technician inspects, cleans, and tests the parts that wear fastest under heavy seasonal load.
A standard maintenance visit with A-Thompson may include:
- Inspecting and cleaning the evaporator and condenser coils for dirt and debris buildup common in the Dallas area.
- Checking and topping off refrigerant levels as needed for proper cooling capacity.
- Flushing the condensate drain line to prevent moisture backup and mold growth in humid summer conditions.
- Inspecting electrical connections, capacitors, and contactors for signs of wear or failure.
- Testing thermostat accuracy and calibrating settings to match your comfort needs.
Each visit may also include a blower motor check and a written report of findings so you know exactly where your system stands.
How Often Should Dallas Homeowners Schedule AC Service?
Most Dallas homeowners benefit from scheduling AC maintenance at least once per year, ideally in the spring before peak cooling demand begins. Because the Dallas-Fort Worth climate extends the cooling season well into October and can bring early heat in March, some property owners with older equipment or high-use systems may find twice-yearly service worthwhile. Catching small problems before summer hits can prevent costly emergency repairs when technicians across the Metroplex are busiest.
Why Local Experience Matters in North Texas
A technician who works specifically in the DFW Metroplex understands the local conditions that affect equipment. Dusty air blown in from West Texas, high pollen counts in spring, and the moisture swings that come with North Texas storms all create wear patterns specific to this region. Servicing properties across Dallas neighborhoods, as well as surrounding communities like Garland, Mesquite, and DeSoto, gives the A-Thompson team firsthand knowledge of how local conditions affect different system types.
