Great service from Bill and his crew. After getting the run around from other companies about the warranty on my air conditioner I gave up and had Ashton install a new unit instead. Quality service and installation and super quick and reliable. Would definitely recommend Ashton Heating & Cooling to anyone!

Paul is the best guy in town! He was very prompt and courteous when our furnace broke down. He was very friendly and willing to explain everything he was doing. I was very impressed with his knowledge, skill and customer service. He was trustworthy and sincere. I genuinely felt like he had my best interest in mind. I learned a lot from him not only about my furnace but about how to best circulate the air in my home and how to most efficiently heat and cool all levels of our home.
