What our customers are saying

My mother is on a fixed income but due to her medical conditions she is unable to experience extreme heat or cold. Her unit broke down around 8 pm. I called several companies who wanted several hundred dollars to just come look at it. When I called Lowell he had no problem coming out and taking a look for a reasonable price. My mothers unit needed a part he had to go pick up however Lowell made sure her unit was working temporarily before he left and returned the very next day to replace the broken part. The unit has been working like a dream ever since. Not only was Callahan Mechanical respectful to my mother and very reasonably priced, Lowell and his son (family owned and operated company) were dependable and very honest. I would recommend this company to everyone. They have a customer for life.
