I found Frontier's contact details while doing a Google search since I was having trouble controlling the humidity in my house. I called and spoke to Ishpal Bhutta . I already had a humidifier but there was condensation taking place on my windows. He was courteous and asked a couple of questions on the phone. We fixed a time and he was punctual. Ishpal identified the part that had malfunctioned on my Honeywell humidifier. He had to order the part but did not charge me for the first visit. He then came by with the part and installed it. He actually ended up quoting much less then he paid for the part but he said since he had given me his word he would stick to his original quote. I really appreciated his honesty and sincerity. I have since referred Ishpal to a couple of my friends for their heating and air conditioning needs and they have found him excellent as well. I will continue to use Ishpal and highly recommend him! I give him a rating of 10.
