Air conditioning units are problamatic to say the least, mine is no different. For once I can sit back and relax knowing Integrity Air conditioning was on the job. That's a rarity in the heating and cooling industry. They are fully insured, licensed and not to mention, "Rosie certified". You need look no further then their name to know what your going to get as far as work ethic and quality are concerned. Integrity will be first on my list in the future for any of my cooling and heating needs.
