Twenty years ago, SUNDANCE Energy Services Inc. installed my furnace and all the ductwork in my house. The furnace is in the crawlspace under the house and the air conditioner is outside, so they don't have to come into the house for maintenance and repairs. The technicians who come out seem to work well together. They always get the job done efficiently. I've been happy with the quality of their products and their good service. They usually respond very quickly when I call and normally show up on time, unlike a lot of other tradespeople out there. I've been doing business with SUNDANCE Energy Services Inc. for a long time and I recommend them.
