    Lassen heating and cooling just installed a new Carrier Infinity heat pump system in our condo…read more Sean and Jacob are very professional, knowledgeable, and talented. They showed up on time and dedicated themselves to our project. I had requested proposals for two other contractors and Lassen gave us the best system at a lesser cost than the other competitors. I would highly reccomend Lassen Heating and Cooling to all my friends and family. Hoping to use them again this spring for our daughters home A/C system.

    Avoid using this company!! They installed an HVAC system in a new build in 2023. The labor only…read morehad a year warranty but the parts were supposed to have 5 years. In July 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 or responsibility for any corrective actions. 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!
