Report
We had a cracked heat exchanger and needed to replace our furnace ASAP since we were unable to use it due to CO poisoning risk. We called sure-fire and Tom was able to give us a thorough estimate and explained all the furnace options over the phone at 3 PM. By noon the next day, we had a brand new furnace and thermostat installed. The installation guys were friendly, knowledgeable and professional. Thank you, again!

Report
Super prompt service and response time. Our technician was polite, professional, knowledgeable, explained everything and had our AC up in running in about an hour. When it's 92 degrees you're very thankful. I liked the online service request form as our outage happened after hours. We got a call first thing in the morning and all repairs were done by 9am.
