Can I Still Use an AC That Has Been Dormant for Three Years?

Even if you don’t use an air conditioner every single year, it probably will run just fine after a period of dormancy. ο»Ώ

Q: For various reasons, I haven’t turned on my air conditioner in three years. Can I simply start it up right now and use it again after all that time? Or do you have to turn it on every year to be sure it’s still OK?

A: Yes, you can turn it on and probably it will run properly. But we advise homeowners that they should have a tuneup done every year on their AC units when they start them up to ensure that they won’t have problems. An air-conditioning technician can check the moving parts and make sure that your refrigerant levels are correct. During the tuneup, a technician may find small problems that can be fixed early before a big breakdown occurs. But even so, in theory your AC should operate just fine.
