The new parts were just put in yesterday. If the compressor fails, that would be about a $1,200 repair, I was told (not by the boss, though). Does that sound right? The new unit would run $3400.
HVAC also recommends replacing evaporator coil. But why replace a completely separate part that hasn't failed yet?
I have already paid the $900 for the repairs done yesterday. The $900 would be applied toward the cost of a new unit, about $3400. I don't see where the great deal is. Please explain.
Also, can you respond to my other issue - buying new evaporator coils, estimated at $2000 or so. Is there some advantage to replacing this when it is working fine and presumably could be replaced when it breaks down later?
How is the warranty different if I were to get the new unit now and the evaporator coil later?
Can't I stagger the warranties -10 years on the new unit, starting now, then 10 years on the evaporator coil, starting later?
The main thing is that you are very very close on the life expectancy issue.If you go with the complete new system now, you will get the new R410 system.This is important as the R22 is being phased out and costs are skyrocketting.It is highly possible that within the next year or so, you could develop a refrigerant leak due to age.When that happens, you will pay anywhere from 200 to 600 bucks to have the system recharged and locate the leak.Then you will most likely be recommended to replace the system as that can be an ongoing thing unless leak is repaired (which 90 per cent of time is at the knuckles or in between coil fins where it cannot be repaired.Then we have the issue with the 12 year old compressor.It is no doubt inefficient and again due to age, is expected to fail within next few years. That is just a fact of life that machinery has a certain life expectancy. Now is it possible that it will last several more years? Yes. Just not probable. The real question here is whether you want to keep spending 900 bucks, 300 bucks,400 bucks etc patching this thing and then purchase a new unit or do you want to go ahead and take care of this issue and not have to worry about it for the next 10 years? Now about the warranties.If you are planning on going back with just an R22 outdoor unit, you will not get 10 years parts warranty. The manufacturer can not sell the unit with R22 as it is against federal rgulations, so they purchase the unit charged with a dry nitrogen charge and then add the rerigerant. Due to the R22 being phased out as mentioned earlier, they only give you 5 years warranty on the brand new outdoor unit.
Just to confirm what I think you are implying - I cannot purchase an R410 unit without at the same time replacing the evaporator coil as well?
The price of $3400 was for the outdoor unit alone. The $907 I have already paid would be credited toward that price. So my remaining payment would be $3400 minus $907.
The evaporator coil would be another $2000 or so.
Spoke with the HVAC company. They offer an R22 American Standard 13 Seer 5-ton condensor for $3780. They offer either R22 or 410A coil, though I wonder now what choice there is since the only have the R22 condensor. I assume by "coil" they mean the complete air handler.
My last question - why would a company offer only an R22?
