Just like your car, your home’s central air conditioning needs regular turn-ups. Cleaning your HVAC unit periodically ensures that the entire system runs optimally, preventing the need to repair a broken air conditioner. Given that half of your energy bills involve cooling and heating your home, each tune-up helps you save hundreds of dollars annually, not to mention lowering the risk of expensive breakdowns. A spring HVAC checklist is the perfect way to stay on track.
