I went with Reliable based on the HomeStars reviews and was not disappointed. In 2012 they replaced our ancient furnace after it broke down in the spring with a new high efficiency one. In 2014 we added a humidifier. Each time we went with Reliable Home Comfort and they have been consistently good. And in the spring of 2015 we added a new air conditioner. In each case the job was very price competitive but not at the cost of good product and installation. They were able to offer a competitive price on our air conditioner plus we were eligible for the $400 government rebate. They responded to our calls quickly, were at our house on time, did great work and accommodated a few special requests and modifications without any complaints or difficulties. Rob and Dave are friendly, professional and extremely knowledgeable about their business. I have no hesitation in giving them a 10 for product and service!
