The technicians from Heat Relief Heating & Cooling were swell fellows. This was our first time using their services. We were referred to them from Northwest Natural Gas. The technicians were prompt, polite and professional. They were able to make their assessment quickly then they took the time to explain their findings to us as well as what they could do to fix it. They also took the time to answer our questions. They were knowledgeable and professional. They were respectful of our home and very courteous. They replaced a gas supply line. We would use Heat Relief Heating & Cooling again!
