Wondering how often to service your air conditioning unit? For optimal performance, most HVAC experts recommend servicing your AC at least once a year—ideally in spring before peak cooling season begins. Regular maintenance improves energy efficiency, extends the unit’s lifespan, and ensures consistent cool air throughout your home. Whether you use a central system, heat pump, or window air conditioner, routine check-ups keep everything running smoothly, lower electricity bills, and prevent costly breakdowns. Stay ahead of the heat—schedule your air conditioning service before the summer rush.
