HVAC Maintenance in Dallas: Keeping Your System Alive Through Triple-Digit Heat
By Tom Bradley
Dallas homeowners ask more of their HVAC systems than residents of almost any other major American city. With summer temperatures routinely climbing above 100 degrees and heat waves pushing the mercury past 110, your air conditioning runs nearly around the clock from May through September. This relentless demand means that a poorly maintained system is not just inefficient but a breakdown waiting to happen at the worst possible time.
A proper HVAC maintenance visit for Dallas homes should go far beyond a basic filter change. Our VENTNEX technicians perform a comprehensive 21-point inspection that includes checking refrigerant charge, cleaning the evaporator and condenser coils, inspecting electrical connections for heat damage, testing capacitors, lubricating moving parts, and verifying thermostat calibration. Each of these items directly affects your system's ability to handle extreme heat.
Location matters too. Homes in sun-exposed areas of North Dallas, Addison, and Carrollton where condenser units sit on south-facing concrete pads can see outdoor unit temperatures exceed 140 degrees. We check for adequate clearance around the unit, verify the condition of the refrigerant lines and insulation, and ensure the condenser fan is moving the correct volume of air. In some cases, we recommend installing a shade structure to reduce the thermal load on the compressor.
The cost of a maintenance visit is a fraction of an emergency repair call during a July heat wave, when HVAC companies across the DFW metroplex are booked solid and parts suppliers are backordered. We recommend scheduling your maintenance in April or May, while appointment availability is high and our technicians can give your system the thorough attention it needs before the heat arrives.
