I've been customer of Harrington for 30+ years and have never been disappointed. Always fixed right the first time. My most recent service was done by Adam, 'AJ'. He was courteous, answered all of my questions, explained what he was doing, and was all around nice guy. I've had two new systems installed by them and when I'm ready for the next one, Harrington will be my choice again. May 2024 they installed a new system, replacing my 22 year old Trane. Again, they did a superior job from beginning to end. Can't say enough good things about this company. I highly recommend them. July 9, 24 Marcus came to investigate a rattling in the condenser unit. Found it in 10 seconds- it was a piece of grass that grew behind the grate and was touching the fan. He was another one of Harrington's customer friendly service techs. Justin did a great job troubleshooting my system when it was down. AJ always comes through with a good semi-annual service and answers all of my questions.
