is it necessary to service ac every year

[DelAnderson]

Yes, servicing your AC unit at least once a year is highly recommended by professionals to maintain efficiency, prevent costly breakdowns, extend its lifespan, and ensure good air quality, even if it seems to be working fine. While some experts suggest twice yearly (spring for AC, fall for heating), annual tune-ups catch small issues before they become major problems, saving you money on energy bills and repairs in the long run.
