Yes, HVAC air filters must be replaced periodically to maintain peak performance. This should be done every 3 months. Dirty air filters slow airflow and reduce your air conditioner’s efficiency, and poor efficiency leads to higher energy bills!
If your air conditioning is not performing properly, checking for a dirty air filter is a good place to start. Our cooling experts supply you with a year’s worth of air filters and an Annual Tune-Up when you become a Star City VIP Member.

Just like your vehicle, your air conditioner and home cooling system need routine maintenance and care to work efficiently. During an AC Tune-Up, a technician inspects and tests your AC equipment for health and performance.
Tune-ups and cooling maintenance are also great ways to prevent major repairs or damage from occurring. Our specialists get a chance to evaluate your AC and make recommendations for preventative measures that will save money down the road.

Refrigerant is the fluid inside your AC condenser that cools air passing through the system. When this fluid is too low, it can lead to an air conditioner that isn’t keeping you comfortable! Look for these signs to spot low refrigerant:

• Hissing or bubbling sounds from your AC unit.
• Ice is forming on refrigerant lines.
• Air is blowing, but it’s not cold.

Air conditioner tune-ups give our Comfort Techs a chance to check refrigerant levels. You don’t want to be caught without working AC on the hottest days! So help your cooling system with an annual tune-up.

Just as you would get an oil change and tune-up for your car before a big road trip, it’s best to get an AC Tune-Up before the heat waves start. When a technician inspects your air conditioning system, they ensure everything is working right and ready for summer.
During a service, a Star City expert will suggest any necessary repairs or upgrades to help prevent AC emergencies when the heat is sweltering. So think about scheduling your AC Tune-Up in the spring or early summer.
