HVAC - Put Your Money Where Your Mouth Is: Part 3

My work continued on our A/C system at the house.  It started with a trip to Home Depot.  Since I needed to replace the insulation on the pipes outside, it was important to pick up some new insulation and zip ties. 

I was so focused on my work I forgot to take pictures, but believe me, the old insulation was falling apart.  It just completely fell apart in my hands.  So I put the new insulation on, and tightened it down with zip ties.  I feel pretty good about it.  Here's the "after" pictures.

The hardest part was just getting around to the back of the units.  The concrete is very hard on the knees.  Luckily, I remembered an old towel I had, so I tucked it underneath my knees. 

I also got back to cleaning the inside coils.  Again, I forgot to take pictures.  But here is what it looked like before.

I talked to my HVAC Instructor Raul yesterday, and he told me to NOT take it out.  Just leave it where it was.  Go ahead and hit it with coil cleaner, and let it sit for five minutes.  Since it sits in a pan, I could use the water hose on low, and the water would drain down the pipes.  I had my shop/vac on standby for any water that made it out of the pan, but not much managed to get out. 

For reference, this is your friend:

So now it's time to let the system run for a bit, and see if everything improves.  It's already gotten colder in the house.  Now it's time to see if the electric bill comes down a bit.  Since this is about the hottest time of year in Florida, the difference should be really noticeable.  Hopefully things will turn out for the best, and I may be able to write part four of this blog.
