Working great!

Thank you for the furnace I installed it over the weekend and it works great. Keeping me nice and toasty!

Great Furnace Core

This brand new furnace core was delivered on time, slid right into place, and has worked great. It's quiet and makes plenty of heat. The core costs significantly less than the whole new furnace, and was easy to replace into the original furnace frame. My original furnace lasted over 30 years, with lots of use, but the blower bearings went out. Replacing the blower required removing the whole furnace from the RV, and then pulling the core out of the frame, and then disassembling the core, in order to replace the blower. However, the next cold season, my original furnace developed other issues. So, I had to pull the furnace from the RV a 2nd time. At that point, even though I had got a smokin' good deal on the used blower assembly, I wished I had scored the entire new core from the start, and got the job done right the first time. By finally replacing the whole core, I now have all brand new parts, and I saved a bundle of cash, compared to buying a complete new furnace. I like the new furnace core. In fact, it's cranking out heat right now.
