"The serviceman from Green Heating Cooling & Electricarrived early, maybe 15 minutes since he had finished his previous job. He was very professional, friendly and courteous. He had a helper/trainee with him. They brought in their tools and went right to work. He said that my furnace filter needed to be changed. He did not have one my size. He told me the size and how to replace it. I bought one the next day and easily installed it. Next he went out side to inspect the heat exchanger which is combined with the air conditioner. He inspected it and replaced some clamp or fitting. Afterwards, it packed up, provided me a receipt, and gave me some advice on how frequently to change the filter and get my unit inspected/tuned up.Checked, adjusted, cleanedmy heat pump furnace. Checked the heat exchanger outside. Replace some clamp or contact item."
