Dolan Plumbing, Heating, Cooling, Electric & Remodeling installed a new HVAC system in our apartment for us. Something was wrong with the first unit, and we began to get a horrible odor from it. We called Dolan Plumbing, Heating, Cooling, Electric & Remodeling, and they came right out to replace the unit for us. The new unit seems to be working fine, but there is still that lingering odor. As far as their service, Dolan bent over backwards to help us. Their service techs were very professional, and always put down protective carpeting as they worked inside. We would definitely recommend the company to everyone!
