My aunt, who bought her house in 1977, is finally thinking about replacing her furnace and A/C this spring.
I got to thinking about this system after she was talking to me about it, because I had not even been in her house since I was 8 years old, but I remember the system rather well.
The furnace was this dark grey gas unit, and I think he name was Brentwood....It is the only furnace I have ever seen with that name on it. I think the name was actually on a label with some kind of logo that was a light blue oval with the name inside of it.
What I always remember more than anything was the A/C. I was always curious how the system worked, but I never have gotten to work on one, and I don't even really see any units like this around anymore.
The condenser was a big blue thing that was made by Servel.
Here are a few things that I always had questions on, but never really knew anyone that could anser them.
1 She had to have a company come out every spring to service it and start it - she said that the original company told her that during the winter when it was not being used, it shut itself off inside and needed to be restarted in the summer. Ever hear of such a thing?
2. The WEIRD sequence of operation. When the thermostat called for cool, the indoor blower started, but the condenser did not start for about 3 minutes after the call for cool. I figure maybe this was a delay on make control, but here is where it gets strange:
When the thermostat satisfied, the indoor blower stopped right away, but the outdoor condenser unit continued to run for about 3 minutes after the thermostat satisfied. I never did understand why.
3. The unit never cycled from the time it was new. She said she had to keep the thermostat at 68 because the house just would not stay cool if she had it any higher. If she let it run 24/7 the unit would keep running until 2 in the morning when the house finally got down to temp, but once it started back up, around 7 or 8 in the morning, it would just keep running all day and into the night.
She said it ran that way from the day it was installed. So, could this mean that the unit was never charged properly from the start? Or is gas A/C just not as fast to cool as electric A/C?
I would love to hear from guys who worked on these - did you like them, were they hard to work on, were they good units, ETC.
