Ellsworth's Heating and Cooling takes care of the heating and air conditioning needs of a home in Florida for me. The last time they came out, they fixed a flow switch for me. My contact there says they showed up on time, and were easy to work with. They did a professional job, and they did it very quickly. From my dealings with them, they seem to know what they are doing, and they do it efficiently. That has not always been the case with some companies I have used, and I appreciate Ellsworth for being a good company with good employees!
