I had a new 5 Ton Condenser and Air Handler installed by L&J. From the start of the project to completion they were on top of my project. From filing the Permits with The TOH to completion.
I called Lou and Julie to get a estimate, Lou was there the very next morning to take a look. He discussed the different types of AC Units and sent me an estimate on Sunday night. We signed a contract the next day. I needed a quiet unit and Lou was spot on with the unit he picked for us. He could of definitely upsold me but was very fair with his pricing actually beat 2 other prices. His crew was neat and very professional, finished on time.
Would Highly recommend this company from… read full review

Hello Julie & Lou! Hope you are well, sorry Iv'e taken this long to leave our review. In a most apreciative way, we could not be happier with our Daikin ductless system. From the initial contact with Julie in setting up appointment for Lou to give estimate, to the installation, we just want to express our sincere thank you's. Funny thing, my wife had a slight medical emergency that day. We had to leave the 2 installation guys at the house by themselves, while I drove her to emergency room. They did a fantastic job. We have had the system for about a year now & all is working great. My wife & I thank you again.
Regards
Mitch G.

L&J have been our go-to HVAC company since we moved to the area. They installed our mini split heat pumps quickly and professionally, and were very quick to respond to questions. Then, when my boiler had an emergency issue on the coldest day of the year, L&J again quickly resolved the problem and were so knowledgeable and helpful. Julie and Lou are professionals, and I trust them to get the job done right. Thank you L&J!
