They come in to check the furnace and the AC once a year in
March. They have been good so far. Since, I have terrible allergies, I spoke to them before I could get the furnace and the AC installed. So, they recommended some special filters on the furnace and a UV light on my central air conditioning system. It helped me tremendously and it was something that impressed me a lot. The person I spoke to said that at that time the UV light was just being developed and it would undoubtedly be available in a couple of years. They were very helpful. I used to pay them each time when they came in to check, but this year they suggested me to go in for the 5 year plan, as it was less expensive. I will definitely use their services in the future as well.
