"My boiler went out and as always it happened on a weekend. I agreed to the extra fee for an emergency call. He was unable to fix the problem on the spot I think, due to a part unavailable on the weekend. They sent somebody back on Monday and fixed the problem while I was at work. When I got the invoice, there was no additional charge for the second visit and it ended up costing me just for the one service call. This was the first time I used Onofrio for my heating. Last April they put a new central air conditioning unit in my home. I was impressed with their attention to detail and service, so called them to handle this problem, and I will be using them for everything going forward."
