We have been very impressed by the professionalism and knowledge of your employees during their visits. The Energy Audit you performed was so informative and although we thought our house was already energy efficient, you suggested additional things we could do ourselves to increase the efficiency of our home even more. At no time did your employees pressure us to do anything we did not want to do. During the most recent visit, your employees spent several hours cleaning and servicing our furnace & air conditioning unit, and from everything my husband & I saw, performed numerous maintenance tasks that we had never seen performed by other heating professionals we had previously hired.
