A/C Pop, Fizzle, Blowing Circuit


First guy came out, removed the side panel and checked the capacitor and then removed the top fan and checked the compressor; the terminals were melted right off and charred. Says the compressor is seized up.

Checked the unit in the attic, said all i would need would be a meter to make a new condenser unit work.
quotes me a 4 ton Trane with meter, 14 1/2 seer installed for $3100. 10 year warranty.

second guy comes out, removes the fan and same diagnosis. Also says the drier downstream from the condenser is about to fail. Says these carrier units are notorious for having failing coil evaps.

Checked the unit in the attic and says the coil evaporator has oil on it, needs to be replaced. Quotes me 12k for a 16 seer Trane with a new furnace, filter, etc, two speed. Also has an Amana unit 16 seer two speed for 10k

Says he can replace just the condenser and coil evaporator with an amana unit for 7k, or just go with a Goodman condenser unit for $2800 and refill the system as needed with the leaking coil.

I get a quote from a 3rd guy, 4 ton, 13 seer american standard for $1975. He still has to come out and check the system to make sure it wont need anything else. This is a R22 unit which he prefers because of the lower pressure (matches existing system).

I can take some pictures of the coil if you guys want to see it to help me determine if it is bad.

What road would you choose?

If the terminals are charred there is a LARGE high percentage chance that the compressor literally burnt out internally. You then get acid and bad contaminants in the system. Need a experienced tech who can flush it with a cleaner and then install suction and liquid line filter driers. Fail to do that proper procedure and your new compressor or condensor may last less than 5 yrs from the contamination. They need to do an acid test on the oil in the compressor to find out but it is a 95% chance it burnt out bad and contaminated everything.

Depends how long you plan to stay in the house and how deep your pockets are $$ wise. I prefer all new lines and a matched indoor and outdoor unit. That way you don't have to decontaminate the system and will have a pristine clean system which will last a long time and have no warranty problems. Adding a meter (metering device TX valve) is an option but anytime you start doing that and mixing and matching components you lose efficiency and have a cobbled together unit which doesn't always work well or stand the test of time. Not a wise way to spend your $$ IMO. If those coils have a history of leaking then a new system is a better choice.

I went up and checked the coil. The coil itself does not have any oil on it, but there is oil at the soldered connection outside of the coil enclosure.

See if one of them is willing to close the service valves on the condensing unit and pressure test the lines and indoor coil. Need to know for sure there's no leaks before thinking about reusing any components or else moisture and air will be draw in when they vacuum the system.

R22 only has a few more years before it can no longer be imported into the US. Recycled R22 will still be around for a long time but who knows what the price will be. I would,and did, get all new using 410A.

R-22 will be around longer than 410-a.

At minimum, change out the condense and indoor coil. Watch out for the super low priced guys. they may not be so quick to come back out if you have trouble under warranty.

The leak was coming from a little farther downstream; looks to be from the original installers. A slow leak over the last 9 years.

I will go with a new condenser and coil; should I upgrade to a larger coil that requires a new transition and plenum or just keep the dimensions I have?

Also what do you guys think of Eco-Temp? One of the installers recommended It as it has a 10 year parts warranty across the board.

Options; all 4 Ton Units


1) 14 Seer Trane condenser & Coil; Replace Plenum/Transition to match larger coil - 410A - 10 year Compressor warranty; 5300
2) 13 Seer American Stanrd condenser & coil; keep existing plenum/transition as dimensions match; 410 or R22 10 Year Compressor (5 if R22), 5 Year Coil $3200
3) 13 Seer TempStar condenser & coil; new plenum/transition to match smaller coil - 410A - 10 year warranty across the board $3200

Get the right Tempstar, and they have a replacement warranty that will replace both the indoor and outdoor unit if the compressor fails inside of 10 years.
