I had an excellent experience working with Comfort Shield Heating and Air Conditioning, LLC. I have been using this company for about a year and a half and I would definitely recommend their service to other people. Most recently, the company did their regular six-month check up for my furnace and air conditioning unit and they also realized that the capacitor needed to be changed. In my opinion, the employees have always been professional and friendly. I also appreciate the excellent follow-up that the company remembers to keep. I would be happy to use them again in the future.
