I have used Ellsworth's Heating and Cooling for several years, and I give them Five Stars in every category! Their techs are very courteous people, and they give me a window of time when they will be here. They always show up during that time, and do not keep me waiting. They also put those little booties on over their feet so as to not track dirt in. I appreciate that. I also appreciate the great job they do for me. They were out recently,and found a hairline crack in one of the elbow joints in the air conditioner. They fixed it right up! Luckily, I had renewed my maintenance contract. I am so satisfied with Ellsworth's Heating and Cooling, that I have recommended them to my neighbors, who sometimes have difficulty getting their air conditioning company to come out in a reasonable time frame. But I don't have that problem!
