The phone number posted does not even belong to the owner anymore. And when I called the number it was a former employee's number. She promised to give my number to Mary Ann but no one ever called me back.

The contact person is easy to talk to and their rates are very affordable and competitive. The workers are professional and courteous, and they arrived earlier than planned. I can hire them again for my future air conditioning needs and repairs.

I was satisfied with the rate and service they provided. I can always ask for their services in the future.

They arrived a little late because of an unexpected problem with a client prior me. I commend the guys who serviced our aircon unit. They were efficient and friendly. In an hour or less, they cleaned the unit and I was satisfied with the outcome. I would definitely contact this service provider again after 6 mos.

Had a bit of delay on the agreed time of arrival, but they informed me right away (so all was good). They responded to questions pretty fast and the quality of service was also good.
