What Our Customers Say

I can’t say enough about J&J Mechanical. They have always treated me in a way that shows me they value my business. Everybody who delivers their services is very professional and knowledgeable. I trusted them to install a new heating and air conditioning unit about 2 years ago. Even before that I purchased their annual maintenance contract because of the work they had done and the value the contract gave me. They are great people and I am happy to have a business relationship with them.
