We found Cozy World using HomeStars, as they were by far the highest rated HVAC contractor. We had a complicated conversion needed to be done, from an oil furnace to a gas furnace, plus we needed a direct vent wall mounted furnace added which involved 175 feet of gas line installed underground. We were willing to pay more for a good contractor, but found that Cozy World was very price competitive, so we chose them, hopeful they would live up to their reputation. Their success is simple....they are very focused on 100% customer satisfaction. They do what they say they will do, regardless of any unforeseen problems they run into. They do their work in a very clean, organized and professional way, for the price they quoted. We actually asked Fred (Farhad) for some extra scope items to be done while he was here with his crew and he did them all and did not charge any extra. We would 100% recommend Cozy World, as they are a great company!
