I chose Energy Experts from Yelp. Kenny came out explained all the options/prices I could make on my decision. He was extremely polite and never pressured me during his estimate. I chose the 3.5 ton AC Pro AC, included cooling coil,heater, ultraviolet sensor, and cooling coil filter I. In addition to these items they cleaned the air ducts and installed an attic fan all for the cost of $6600.00. This I felt was a great price considering other quotes I received were too expensive. Also included are the cost for permits and energy inspections from the state. Bare in mind this took 1 and 1/2 days to complete because of the parts I selected. However, they made sure I had the A/C up and running the first day and completed the job the following day. One thing I admire about this company is they follow state energy requirements, they do a professional job and leave your home clean of any debri. Also they go over everything concerning the work they did and how to operate the system. You can't go wrong with this company and the unit runs great better than the one that came with this house when I bought it new.
