Lennox Air Conditioner Maintenance & Service
Give your air conditioner a little love with annual maintenance, and it will love you back by staying as efficient and problem-free as possible. But even the best air conditioner will need some repairs from time to time.
As your air conditioner ages, it depreciates in value — kind of like a car. And you don’t want to put thousands of dollars into a car if it’s not going to improve in value, just like you don’t want to spend thousands of dollars on air conditioner repair when you could get a new one that works much better.
Keep your air conditioner in top shape and help prevent costly, unexpected repairs with the Summers and Smith Elite Program, which includes our Annual Preventative Maintenance Program.
