AC Tune-Up FAQs
You can always contact our team with questions about HVAC installations, repairs, or maintenance. Here are some questions our customers often ask!
Do I need to replace my air filters?
Yes, air filters must be periodically replaced in central and mini-split cooling systems. Ideally, this should be done every 3 months. Dirty air filters slow down airflow and reduce the efficiency of your equipment.
But don’t worry, Cencal Gold Plan Members receive an annual supply of air conditioner filters to keep their system running right all year long.
Why isn’t my air conditioner cooling?
If you’re not getting any cool air out of your home’s air conditioner, there are a few things you can check for:
- Make sure there is power to your unit. Check your circuit breaker.
- Ensure air filters are clean.
- See if the coils are frozen over. If so, turn off the unit until they thaw.
- Is the thermostat working normally? Try adjusting the temperature and wait for a change.
If AC issues are popping up consistently, it’s best to have a professional assess your unit. We’ll tune-up your air conditioner for peak performance.
Is my AC refrigerant low?
Refrigerant is the fluid inside your AC condenser unit that cools air passing through the system. When this fluid is too low, it can lead to an air conditioner that isn’t cooling! 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 HVAC techs a chance to top up 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.
When is the best time for AC maintenance?
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 properly and ready for summer.
A service professional can suggest any repairs or upgrades to avoid AC emergencies when the heat is sweltering. So think about scheduling your AC Tune-Up in the spring or early summer.
