In 2018, we chose Aspen to replace a standard gas log fireplace that sent more heat up the chimney than into the house. We had intentions of doing a ventless system, but they recommended installing a direct vent fireplace. They also took the mantle area down to the studs and rebuilt it to code, using a stone finish and custom mantle. Aesthetically, it was a huge upgrade to our house, and functionally it has been great.
Today (1/26/21) was the first time we needed to call for service, thinking the draft we were feeling was from a seal that might have opened up. Needless to say, Pete came out, talked through what the issue was (it had nothing to do with their craftsmanship or product failure), reminded us about yearly maintenance needs and was on his way.
Both experiences have been great. The team is clean when they are in the house, attentive to questions you have and overall a great business to work with.
