Another DIY Project

I noticed that the air blowing out of our furnace vents seems weak this year. Something needed to be done. Shouting, “To the net,” I did some research. The first thing I did was change the filter, which helped — that rascal was filthy. I then set a calendar reminder to check and change it every three months. Then I visited the crime scene for clues.

Our furnace is a Tempstar L9 unit horizontally mounted in the attic above the garage. I’ve been up there to deal with problems before so I’m comfortably familiar with it. It’s our original unit, so it’s almost sixteen years old. I’m embarrassed to admit, the blower hasn’t been cleaned since the capacitor failed ten years ago. I decided to do two things, based on research: clean the blower and increase its speed.

Both were easy, with the second part being easiest. The heating and cooling systems use the same blower and ducts (yeah, duh). But the wiring on my system can only specify that one of them has the higher blower setting, and that is the A/C. So I switched it so the heating has that setting for the winter. Before I started messing with the wires, I perused the manual’s wiring table and instructions and then photographed the original wire placement with my phone. I’ve learned to do that last anytime I’m dealing with switches and wires. It’s saved my butt a few times.

Now it’s all much improved. I’m once again grateful to the net and its helpful videos. Finishing, I set another calendar reminder for the summer, so I can go back up in there and switch over the wires for the air conditioning. Have a good one. Cheers
