I called up Larsen Energy Systems after a referral from a friend to ensure my HVAC system and bathroom vent were adequately sealed and ducted. I'm happy to say that Casey and team are both friendly and reliable, not to mention they completed the work in record time without sacrificing quality. Like others have said, I don't think there is a better HVAC company in the area for the price.
Our furnace went out during a cold spell. Our 1st contact said a major component was defective and the furnace should be replaced. The price they quoted was shocking. Our 2nd contact was incompetent, and wasted a week. Casey was recommended by our realtor. He diagnosed the problem down to 2 small components, replaced them and started the furnace at a fraction of the 1st contacts price. We were very pleased with the friendly and competent service.
I had an excellent experience with this HVAC company. They quickly diagnosed a heat pump issue that several others couldn’t figure out and fixed it efficiently. I hired them again to install a new AC at another property. They did an excellent job and vent above and beyond. Their team is professional, highly knowledgeable, and very reasonably priced. I’ll definitely use them again for any future HVAC needs.
We were coming off a full-on mold nightmare and needed someone who actually knew HVAC, ducts, furnace, airflow—the whole thing. The second Casey walked in, you could tell he’s been doing this forever. More than that, he cared. We weren’t just another job; we had a weird, tricky situation and he treated it like it was his own family’s place. He’s a perfectionist (in the best way). No corners cut. Worked around our schedule. Explained options without upselling. He brought in the right folks when needed, redesigned our duct layout, and got us real airflow back in the rooms that were always stuffy. He replaced all the ductwork, sealed everything, balanced the air, and even cleaned up the crawlspace before installing the new ducts so the system wouldn’t pick up junk down the road, little details we never would’ve thought of. Finally, as we speak the air feels clean, temps are even, HVAC runs more efficiently, and the whole system just… works. After months of remediation and legal back-and-forth, Casey stayed positive and kept moving things forward. The seller before us left us with a jimmy-rigged liability and now our small family is honestly forever grateful for a what feels like a new system. If you’re anywhere in Sonoma County and need an HVAC contractor for duct replacement, furnace or AC install, indoor air quality help after mold, or just better airflow, go straight to Larson Energy and ask for Casey. He’ll get you the best value and the right fix. Heating and cooling, ductwork, energy efficiency, these guys are the real deal. Thank you, Casey.
casey himself helped me with my aging ductwork in bennett valley. i had an obvious leak and failure points in a few areas in my system that he identified immediately. aggressively competitive pricing surprised me a bit, because i’m more used to some of the bigger guys. wanted to wait a few months to review properly because of the lower price, and happy to be able to say wow - job done perfectly, and he was really natural and easy to work with. pretty strongly recommended if you have needs on a 30-40 year old home in sonoma county and if you’re on a reasonable budget but still want an actual local professional who doesn’t constantly upsell or find fake problems.
