7 Signs Your AC Needs a Tune-Up Before Texas Summer
Texas summers hit hard. With temperatures soaring across San Antonio and the surrounding areas, your air conditioning system becomes a necessity for your home’s comfort. But if your AC isn’t ready for the heat, you could deal with breakdowns, poor airflow, and sky-high energy bills. So, how do you know it’s time for a tune-up? In this blog, our HVAC experts at Damiani’s Comfort Design cover the top signs your AC needs attention before the next heat wave hits.
Why AC Tune-Ups Are Essential in Texas Heat
Living in Texas means your cooling system works overtime during the summer. Regular tune-ups help ensure your AC runs efficiently, reliably, and safely. Maintenance keeps internal components clean and calibrated, which reduces the risk of emergency repairs. It also keeps your system energy-efficient, which helps lower monthly bills and keeps your home cool—even during triple-digit temperatures.
Sign #1: Weak Airflow or Uneven Cooling
Do you notice some rooms feeling cooler than others, or not cool at all? Weak airflow or inconsistent cooling could mean clogged filters, ductwork issues, or problems with your blower motor. A professional tune-up will clear blockages, check airflow performance, and ensure even cooling throughout your home.
Sign #2: Unusual Noises or Odors
Your AC should run quietly and without strange smells. Buzzing, grinding, or rattling sounds could point to loose or damaged parts, while musty odors may indicate mold or mildew buildup inside the unit. During a tune-up, your technician will inspect and clean internal components to address any noises or smells before they turn into major problems.
Sign #3: Rising Energy Bills
If your energy bills are climbing without any change in usage, your AC may be running inefficiently. Dusty coils, poor airflow, or low refrigerant can make your system work harder than it should. A tune-up improves efficiency, which helps cut down on energy costs while keeping your home comfortable.

When your AC frequently turns on and off or runs for unusually long periods, something could be malfunctioning. These patterns often result from issues with sensors, refrigerant levels, or airflow problems. A professional tune-up can recalibrate your system to help it run at optimal intervals.
Sign #5: Thermostat Not Responding Properly
If your thermostat doesn’t seem to match the temperature in your home or takes forever to respond, your comfort could suffer. Tune-ups often include thermostat testing and adjustments to make sure your system reacts accurately and efficiently to your settings.
Sign #6: Moisture or Leaks Around the Unit
Water or refrigerant leaks around your indoor or outdoor unit shouldn’t be ignored. They could signal a blocked drainage tube, frozen evaporator coil, or refrigerant issue. These are all items checked and corrected during routine maintenance.
Sign #7: You Can’t Remember the Last Tune-Up
If it’s been over a year, or you can’t remember the last time your system was serviced, it’s definitely time for a check-up. Regular maintenance helps catch small issues early and ensures your system doesn’t break down when summer hits full force.
What Does an AC Tune-Up Include?
So, what is an AC tune-up exactly? A comprehensive AC tune-up includes:
- Cleaning the condenser and evaporator coils
- Checking and topping off refrigerant levels
- Replacing or cleaning air filters
- Inspecting electrical connections and tightening if needed
- Testing thermostat accuracy
- Lubricating moving parts
- Calibrating the entire system for proper performance
All of these tasks work together to keep your AC running smoothly and efficiently, especially during high-demand summer months.
