Prompt, courteous service! I called after 4 yesterday afternoon and they arrived today around noon (I was told between 12 and 2!) They quickly diagnosed the problem, gave me options and quoted me a very reasonable price. They had to go get the part and told me they had some other calls, but would be back as soon as they coukd. They were gone less than an hour! They got my air conditioner up and running in about another hour. J.F. Maxwell had done some work for us in the past also, and we will continue to call them in the future. Terrific people and company!
