Diagnosed and fixed an issue quickly. Arranged an appointment within minutes and fixed the next day. Sean also inspected the duct work and replaced our thermostat. Great work.

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.

Really great thing to find a professional with such a pleasant process. Sean is what we look for in a pro being that he is great at communication, work quality, professionalism, invoicing, service, and payment methods. He works with many other property managers and makes my job smoother.
