Maria was very thorough and quickly identified the issue with our AC. The quote was reasonable, and I’m very glad we found Sullivan to help extend the life of our system. Thank you for the excellent service!

Woke up to cold shower this morning. Called Sullivan and had immediate response. Jerry evaluated the situation and in a few hours Marie and tech were here to install a new Bradford White hot water heater.... made in the USA was a bonus!!
Excellent service, professional and personable while getting the job done. Cannot thank them enough for being there for us.
