Central Texas spring lasts about six weeks before summer takes over. That window is your best opportunity to prepare your HVAC system for the months ahead. Here is a practical checklist that Georgetown and Central Texas homeowners can use to get their systems ready before the heat hits.
Outdoor Unit
Clear debris from around the unit. After winter and spring storms, leaves, branches, and mulch accumulate around and under the condenser. Clear at least two feet of space on all sides and check underneath the unit for debris that could restrict airflow.
Gently rinse the condenser coil. Using a garden hose with moderate pressure, rinse the coil fins from the inside out to remove built-up pollen and dust. Never use a pressure washer, as it will damage the fins. If the coil is heavily coated, have a technician clean it properly.
Inspect the refrigerant lines. Look at the insulated copper lines running from the outdoor unit to your home. If the foam insulation is cracked, torn, or missing, replace it. Damaged insulation reduces efficiency and can lead to condensation problems.
Check that the unit is level. Over time, the pad beneath your outdoor unit can settle unevenly. A significantly unlevel unit puts stress on the compressor. If your unit looks noticeably tilted, have a technician assess it.
Indoor Air Handler and Ducts
Replace the air filter. Install a fresh filter at the start of each cooling season. Make a note to check it again in four to six weeks once your system starts running more frequently.
Check the condensate drain line. Your air handler produces condensation as it cools your home. The condensate drain line removes that water. In spring, algae and debris can block the line. Pour a cup of diluted white vinegar down the drain access port to clear buildup. If your system has a float switch, verify it is working by pouring water into the drain pan.
Inspect visible ductwork. Check any ductwork you can access in your attic or crawlspace for obvious gaps, disconnections, or tears in the insulation. Leaky ducts in a hot Central Texas attic are a significant source of energy waste and uneven cooling.
Thermostat and Controls
Test cooling mode before you need it. On the first mild warm day of spring, switch your thermostat to cooling and verify the system comes on, reaches your setpoint, and cycles off normally. Do not wait for the first 95-degree day to find out something is wrong.
Check thermostat calibration. If your home feels warmer or cooler than your setpoint, the thermostat may need recalibration or replacement. A smart thermostat that learns your schedule can also reduce runtime and lower energy costs.
When to Call a Professional
This checklist covers what homeowners can reasonably do themselves. A professional spring maintenance visit goes deeper, including refrigerant pressure checks, electrical component testing, blower motor inspection, and full system diagnostics. We recommend scheduling professional maintenance before temperatures consistently exceed 85 degrees.
