Do the AC condenser and evaporator coil need to be replaced at the same time?
Yes they do need to be replaced at the same time and he does not need to look at it to know it. Condensing units now do not use the same refrigerant as a few years ago and they are not compatible with the oil either. Evaporator coils need to be matched to the condenser for proper operation and compressor life. He was truthful in that they should be replaced at the same time. What he is hiding is that Goodman is a crappy unit. They are cheap and a step up from a mobile home unit. If you are looking for right now cheap Goodman is a good idea if you are looking down the road long term cost look at Trane, American Standard, Ruud, Rheem. Those are the top 4 on consumer reports and I will concur as I service all brands and those are the better of them all. You should get at least 3 estimates. If you piss em off who cares. I sell them and ask them to get more estimates. Look for someone who will educate you on the purchase you are about to make. If they can not teach you about this unit so that you can understand get another estimate. And last but not least cheapest is not always really cheapest in the long run.
I was told i need an evaporator coil replaced on my 28 year old AC unit. Do i need a new condenser as well?
I have a home warranty under American Home Shield and my AC in the attic needs a new Evaporator Coil. The unit is 28 years old and American Home Shield wants only to cover the replacement of the evaporator coil when 2 other estimates said I need to replace the evaporator coil and the condenser, one which said the the compressor has bad valves. I read online that both should be replaced at the same time since they need to match. The unit is an 8 SEER unit which I know is ancient. Is the new evaporator coil going to be compatible with my original condenser if American Home Shield only wants to pay for the repair? Also, they want to charge me for permits, disposal and R22 recovery. Is that normal?
AC evaporator coil replacement.?
I have a AC evaporator coil leak that now requires freon to be added every few weeks. It is a 3 ton 10 year old unit. The condenser unit is working fine (AC technician checked amperage - pulled 12.5 amps vs units max of 15.4). I am weighing replacing the coil only or replacing the entire system (coil and condensor unit). There is a substantial cost difference ($1700 vs. $6000). If I elect to replace the coil only with a compatible 3 ton coil, will it be compatible with a new condensor unit when my existing one fails? Would it be compatible with R410 if/when we need to replace the condensor after R22 is phased out?
Can R22 coil be used with R410-A condensor?
R-410a operates in the same way R-22 does but it will be at higher pressures. R-22 systems are not designed to operate at the pressures R-410a displays. You will need to replace the indoor evaporator coil with one designed for the greater pressure.
10 year home. AC guy wants to sell me a new unit due to a "small" coil leak.?
I called my Home AC company for a routine year inspection, no big deal. He says that my coil has a "small" leak and he tries to sell me a whole new AC unit (SEER 17, R410) costing nearly $12,000.00. Currently, I have R22 and it is cooling fine. He says R22s parts are running out "soon", doesn't tell me when. I feel like he's trying to "sell" me a unit. What should I do?
Can you retrofit an a/c condenser and a coil that takes the old r-22 to the new freon out now?
Now, in theory, its possible if you cut the coils out and flush them about 7 times, all of which costs more than new coils. But Polar bear is right, the new refrigerant, R410a, operates at twice the pressures and older R22 coils are not designed for those pressures. If I were your adjuster, I would get you a new 13 seer R22 Condenser, put a TXV valve on your coils, if they do not have one, to make them compatible with the new Condenser and fill it with the NU22 refrigerant, or give the cash equivalence and let you pay the difference if you want
Converting from a R22 Air Conditioner to a R410-A?
I'm asking this question for my dad. He recently has been having problems with his outdoor unit making noise. It is a Comfortmaker Soft Sound 1200+. He called someone out and the technician thought it was the fan motor. So he changed that, but it still makes noise, so now he's thinking it's the compressor, they also found it to be leaking coolant I guess. They're talking about replacing the whole outside unit, I'm not sure what type. It will be switching from a 12 SEER to 13 or 14 SEER, probably same tonnage. Anyways reading up on it I see they are phasing out the R22 coolant and going R410A, my question is what would need to done to make the change to R410A? I've read online you need to replace the duct work, I've also read when you convert you should have your ducts inspected and sealed. So which is it do they need to be replaced or just sealed? Does portion of the air conditioner inside the house have to be replaced if you convert to the new coolant. Also if you switch you either need new lines or have them flushed with nitrogen, is that correct? So that's my question, what needs to be done to convert from a R22 unit to a R410-A unit? His house was built in 1997, but the outside air conditioning unit that he has right now was replaced in 2008, if that helps.
