Barely a year old furnace wouldn't ignite. Called Carleton Refrigeration that night and had a tech out the next afternoon. Of course it started right up for Owen. He still checked everything out, but without the error codes couldn't find anything. He showed me how to check and we caught them - needed a new gas valve. He calls to let me know when he's on his way, is very professional and knowledgeable, takes the time to explain what's up without talking down to me and cleaned up after himself. And thanks to Ashley for the quick call back and appointment. Great customer service every time..
