Darek was fast to respond, professional, and gave me a good price without cutting corners (in fact, he went out of his way to do it right). My mini split was installed and working perfectly within about a week of my first call, and Darek was helpful and thorough the entire time. It's been several months since it was installed and I've had 0 issues, the system is working perfectly. Thank you!

We have our heating system for about 2 years now, and we always felt that the furnace was running too often and barely keeping up to heat the house when it was very cold outside.
When Derek came I explained this to him. He checked the entire system. He readjusted the furnace, increased the temperature of the outgoing air and also checked the temperature of the return air. He did a very diligent job, with the result our house feels warm, even at temperatures below 0. The running time of the furnace is decreased and we feel very comfortable.
Congratulations to such service personnel like Derek.

You have to see it to believe it! Fantastic installation of brand new Lennox furnace, pleasant and excellent workmanship. Job done right by professionals (Derek J and Darek B). Just can't explain how happy I was with the install. It seams, I am getting much more air out of the vents than before. Will be recommending to my friends for future work!

We were extremely happy with the quick response (the tech was here within 3 hours of my initial call) and the fast and accurate diagnosis and repair. We also appreciated a company that has someone available to answer the phone rather than some slow-responding message service. The tech was courteous, knowledgeable, and isolated the problem within minutes and had us enjoying heat again within the hour. We won't hesitate to call Littleton H & A/C again if a need arises.

What a relief to have real professionals who don't just hand you a quote, but explain what things mean and why. They took the time to make sure I knew not only how everything worked, but why it works that way. Courteous, polite, organized AND efficient...and that's saying something because our situation was a mess due to fault of the previous company. You can't go wrong with Littleton!
