I've been reading many posts on this forum and a few others trying to find answers and have decided to post and ask all of you knowledgable folks for opinion.
Please forgive me for not knowing all the proper terms for parts....my job is to take care of the kids and to make the house freezing cold...how it gets cold wasn't my problem until the last couple of weeks.
2 story home with upstairs unit and downstairs unit, and furnace in the attic built in 2004. We are the 2nd owners, bought in '07 and quite frankly, other than change the filters a couple times a year, the only time its been serviced is after a problem.
The units outside are Carrier
s/n 4104E10193 & 1096
When we first moved in 5 years ago, one of the units had a small leak and got a charge (I can't remember which one).
A year ago, we had the drip pan in the attic replaced because it was rusting out and dripping rusty water down the outside of the house.
Two weeks ago, a friend replaced the fan & capacitor on the unit outside. I'm fairly certain he knew what he was doing because he works for an electrical/HVAC company and does this sort of thing every day.
This past week, the same unit that got the new fan and capacitor froze up. My friend said that he couldn't charge it, but his employer could because of the licensing of the freon? He came out yesterday, checked up in the attic, went outside, had some gauges, etc.
His answer was that the coil in the attic is shot. I had 3 options.
1. charge it and next year I will need to charge it again & again (agreed that it was an incredibly stupid non-option)
2. replace the coil in the attic and hope that nothing happens to the unit outside (because then I have to replace the unit in the attic and the one outside so they match???).
3. replace both now with new a new system (I am guessing that both outside units are replaced??)
We are leaning towards new, because we've had problems already, but have also read on some forum posts that 8 years isn't that old, yadda, yadda.....
I am expecting a quote from him, and have 2 others coming on Saturday to quote new systems.
