What Your HVAC Contractor Should Check During Seasonal Tune-Ups

As temperatures shift in North Texas, your HVAC system must be ready to perform at its best—whether it’s battling the summer heat or taking the edge off a winter chill. The best way to avoid breakdowns and ensure long-term efficiency is through seasonal HVAC tune-ups. But not all tune-ups are created equal.

At Texas Air Authorities, we believe in being thorough. Our NATE-certified technicians follow a detailed checklist during every seasonal maintenance visit to ensure your comfort system is running safely, efficiently, and reliably. If you’re hiring an HVAC contractor, here’s what they should be checking during a seasonal tune-up.

1. Thermostat Calibration and Functionality

Your thermostat is the command center of your HVAC system. If it’s not reading temperatures correctly or communicating properly with your unit, you’ll notice inconsistent temperatures and higher energy bills. A technician should:

1. Verify thermostat accuracy
2. Ensure it’s responding properly to commands
3. Replace batteries if necessary
4. Reprogram your schedule for seasonal needs (if applicable)

2. Air Filter Inspection and Replacement

A dirty or clogged air filter restricts airflow, causes strain on the system, and negatively impacts indoor air quality. During a tune-up, your technician should:

1. Check the condition of the air filter
2. Replace it with a new one (or recommend a suitable type)
3. Offer guidance on how often to change it based on your home’s needs

3. Inspect and Clean Evaporator and Condenser Coils

Dirty coils reduce your system’s efficiency and cooling ability. Over time, buildup can lead to overheating or even a system shutdown. Your HVAC technician should:

1. Inspect the indoor evaporator coil for dirt and mold
2. Inspect the outdoor condenser coil for debris, leaves, or grime
3. Clean both coils as needed to restore proper heat exchange

4. Check Refrigerant Levels

Low refrigerant can cause your system to run longer, cool less efficiently, or freeze up entirely. A technician should:

1. Measure refrigerant pressure
2. Check for signs of refrigerant leaks
3. Recharge the system if necessary and discuss long-term solutions if leaks are present

5. Inspect Electrical Components and Connections

Loose or worn electrical components can cause short circuits or dangerous malfunctions. Your contractor should:

1. Tighten connections
2. Inspect wiring for signs of wear, corrosion, or damage
3. Test capacitors, contactors, and relays for proper operation

6. Clean and Clear the Condensate Drain Line

Condensate drain lines can easily clog with algae or debris, leading to water leaks and potential property damage. Your technician should:

1. Flush the drain line
2. Inspect the drain pan for standing water or rust
3. Ensure proper drainage to prevent future issues

7. Inspect Blower Motor and Fan

Your blower is responsible for circulating air throughout your home. If the motor or fan is dirty or failing, it can severely affect performance. During the tune-up, your technician should:

1. Inspect and clean the blower motor and fan blades
2. Check for proper airflow and motor function
3. Lubricate moving parts (if needed)

8. Test System Startup and Shutdown Cycles

To ensure smooth operation, your contractor should test the full cycle of your system from start to stop. This includes:

1. Ensuring the system starts easily
2. Observing the unit while it’s running
3. Confirming it shuts off properly once the target temperature is reached

9. Evaluate Ductwork and Airflow

Your duct system is vital to distributing air throughout your home. During a seasonal check, your HVAC technician should:

1. Look for visible leaks or damage
2. Test airflow in different parts of the home
3. Recommend sealing or insulation improvements if needed
