I highly recommend Sean for any HVAC needs! He responded extremely quickly and was incredibly friendly from the moment he arrived. What I appreciated most was his honesty—he gave me a very fair and transparent assessment of my system without trying to sell me things I didn't need. If you’re looking for someone reliable and honest to work on your HVAC, look no further.

My furnace broke during a cold snap and my place was freezing with little ones. The other contractor quote an amount that didn’t fit my budget, but then I spoke with Sean from UltraCool and he can right over to assess, sans service fee, and offered up solutions that were 50% less than other guy. He even advocated on my behalf when vendor with repair part lied about the part. This effort meant a lot. His diligence and follow up exceeded my expectations.
