Our contractor hired Mancini to install new radiators and through-the-wall air conditioning in our second story extension. They did a great job, and were very friendly and helpful, so we switched to them when it was time to maintain our existing main-floor air conditioner. It was an older and less common model, and we really appreciate that the company took the trouble to send their professional most familiar with this type of air conditioner rather than just the person already working in the house, and we were also impressed with the detailed cost/benefit explanations they provided in terms of repair options. Great service - highly recommended.
