Excellent Service
I needed a new fan motor for my air conditioner. Jack replaced the motor and it ran for about 30 minutes and stoped. I called the company and explained what I had observed and they sent Mark out the next day to replace the motor and the same thing happened. They ordered a replacement motor from the air conditioner company, Mark installed it and problem was solved. This was all done very professionally and within a reasonable time period.Great company to deal with.
Jack is a very knowledgeable technician. He serviced my AC unit and found the fan motor was on its way out. He showed me the problem with the motor and had a replacement on his truck. Jack is very friendly guy and does not hesitate to discuss what he is doing and why. When he was finished, I received a complete report on items he had tested or inspected. I am Pleased he will be handling my HVAC system. Gina was also very helpful in arraigning my appointment.
Jack was very polite, knowledgeable and thorough in solving our AC problem.
