Lassen Heating and Cooling LLC

I recently had a heat pump installed on the second floor of my new home by Lassen Heating and Cooling LLC, and I couldn’t be more pleased with the experience. From the beginning, Sean took the time to understand my needs and make sure I had the perfect unit for my space. His expertise and attention to detail were immediately apparent. The installation itself was incredibly efficient. Sean and his team completed the entire job in just a day and a half. Watching them work was like watching a well-oiled pit crew in action. They moved seamlessly from room to room, installing ductwork with precision and care, all while keeping everything immaculately clean. Now I’m sitting in a comfortably cool room, and I’m also looking forward to lower heating bills this winter thanks to the energy efficiency of the heat pump. I highly recommend Lassen Heating and Cooling to anyone looking for knowledgeable professionals, quality work, and top-notch customer service.

Avoid using this company!! They installed an HVAC system in a new build in 2023. In late July and early August 2024, the upstairs HVAC system in the home stopped providing cool air. Sean Lassen was contacted multiple times over email and phone to ask him to investigate the problem. He only responded to our inquiries when the builder reached out to him and asked him to contact us. Unfortunately, instead of going out to the house to investigate the issue (his website says he offers 24/7 emergency service but couldn't offer me any timetable to come out other than to say it would be several weeks before he'd have time) he offered excuses about being too busy, being too far from the location of the property, not having good employee support since COVID, and then mentioned that we would be outside our warranty anyway. I had another HVAC company go out to diagnose the problem and the builder also investigated the problem directly. Ended up having a different HVAC company install a new flare, reconnect the pipe, add refrigerant and test the system at a total cost of almost $1700. Lassen HVAC is completely unresponsive to homeowners, takes absolutely no interest or accountability for his workmanship and responsibility for any corrective actions that might be needed after the fact. Did I mention that we missed out on a couple thousand dollars in rebates when our system was installed too because he never got us the paperwork we needed?? DO NOT USE THIS COMPANY!

Above i wrote a neg review for Lassen Heating - there was a misunderstanding. Mr lassen worked with me directly for a long time. the issue is NOT with Lassen i see now. the issue i have is with Carrier brand Support. I bought the house 2 years ago and Mr Lassen installed the system and he was never called to service it for many years. today we talked and he assisted me and offered me some valuable advice. i appreciate his time and patience.

My experience with the Lassen HVAC company has been limited because not because I haven’t tried over and over and over again to get in touch with the owner of the company who originally installed a carrier infinity HVAC system in my home in Northwest Connecticut. I have not received any phone calls back and I have been trying to diagnose a fourth code for over one year at this point And have left numerous voicemail friendly messages to ask if they could come over and try to diagnose the situation. They were the original installers. I bought the house two years ago and would’ve like them to do the original service but never got a call back. Disappointed and frustrated .
