I have been a customer with Dominion Service Company for more than 10 years. They installed my heating and air conditioning unit in 2000 and I have had a servicing agreement with them since installation. Their service is excellent and deal with my messy garage with no complains. I recently purchased an office condo and Dominion Service installed the whole system. Very ethical in my pricing and they also service the system under a servicing agreement. In all my years, I consider them the best in the business.
