Mace Energy while I have had limited experience with them. They have been one of the best Supply companies to get parts from, even when they don’t service your brand. And they actually have them in stock. And the next thing I highly recommend them for is they have absolutely the BEST wood pellets to burn. They also sell Coal in several different sizes. They are also very friendly people, and very knowledgeable with Harman pellet stove, as that is what they specialize in. Highly recommended company.

We have a 19 yr. old Harman Advance, and always call Mace Energy when we need replacement parts. They usually have what we need in stock, at very reasonable prices. I called yesterday morning about a failed pressure switch, and although the Harman part number had changed, they had a new comparable switch in stock. I installed it today and our stove is up and running again. Thanks once again, Mace Energy.
