Our furnace is dead! The main controller circuit board is shot and the blower motor is on it's last leg. It's 20 years old, so it's had a good run!
As we are looking at a replacement, I'm considering adding a HEPA filter. The one that they use is an extra box that goes on top of the furnace and takes an April Air filter. He didn't put the model number on the estimate, so I'm having trouble figuring out which product it is.
Anyone have experience with HEPA filters on their furnace? We only have forced air heat – no A/C. So, this would only help me in the winter when the heat is running. Trying to figure out if the extra cost bump is worthwhile.
