Cameron and Mateo did a great job, explained what they were doing, and showed pictures of the inside of the ducts as they were cleaning them. Very satisfied with our duct cleaning

Cameron was able to diagnose a problem that was intermittent quickly and then complete repair. All of our interactions w One Hour have been great. Our furnace is on the roof - not everyone is willing to work on that. They have earned our loyalty over years of maintenance and service that is always timely and courteous. Highly recommend.

Very nice people and great customer service. However, I was told I needed an entire new furnace. I got a second opinion and it was a simple part that needed replacement. I got quotes from both companies for the part replacement and the other company was less than half the price of One Hour Heating.

Job was done great! Only problem is cleaning the tools in my basement sink leave black crap and not cleaning it up. Great job professional but leave my sink with black stuff would have been a nice clean up or warning.
One hour ALWAYS does a wonderful job! Thank you! Happy holidays!
