They addressed issues I new a had with my air conditioning unit and located other issues with the hot water tank that was not identified by the previous hvac company (C&ffi) whom I received an outrageous proposal from to do the work. There price was lower to do both jobs than the previous company. I highly recommend them if you don’t want to be taken advantage of. IMAGES 1-3 REPAIR NEEDED 4-6 REPAIRS MADE.
