I think the OP is talking about the fan on the outdoor unit, which isn't controlled by the thermostat. Is the unit still calling for a/c or heat when the outdoor fan keeps running and the compressor turns off? Compressor could be cutting out on a safety (low charge, high pressure, etc.). Or the unit could be turning off but the fan keeps running due to some other problem. You need a tech to diagnose the issue properly. Can't be done with accuracy over the internet. Good luck.

Thanks for the reply. No, I'm not looking for the rock bottom price but I can't afford the top of the line either. I don't know the model number but I will find out tonight and post it. The only additional info I have is that the coils are being wrapped because of the China sheetrock problem, just in case. He will install a damper and some type of air exchange. The HERO program must be only in Louisiana. It is an energy conservation program that gives up to $2000 in rebates to make your house energy efficient. They suggested that the installer do some "J" (I don't remember the exact name) thing to determine the size unit needed. Something to do with measuring the rooms and calculations of the air needed for each room. They said it should already be included in the price of the system but it isn't. I guess my concern is that we've already had 6 people out and haven't been able to get a concise answer about the size of the unit needed from any of them. They all push their brand of machine as the best. At least I've heard of the others, I've never heard of Goodman. I know it's made by Amana but have they cut corners to make it? I know I'm not required to up grade the unit in 10 years but I assumed the machines will be that much more energy efficient in 10 years. So is the savings of $4000 worth it with this machine? I don't want to have it broken down weekly or monthly. I also don't want a lot of noise outside my kitchen window or higher energy bills because it's the bottom of the line. The installer insists it isn't the bottom of the line grade. He also sells Amana and, I think, Rheem but he's really pushing this unit. He's a friend of a friend so I don't know if he is really trying to help us or what.

This is my biggest issue with Goodman - the piss poor filter rack in the air handler. I had my Goodman ARUF air handler for about a month before it was installed so I got to look it over well before the install. The guides for the 1" filter do not have a smooth surface as they are part of the frame of the air handler. I had to add 1.5 inch wide smooth metal straps on top of the filter guides. I held the straps in place with a few dabs of auto-body putty. I also had to trim the back piece of foil-face insulation where the back of the filter would seat. After doing this surgery, I am now able to use a 20x24 filter that I get from www.ushomefilter.com Note that I still have issues when replacing the filter. I literally have to rip out the old filter as the cardboard frame gets caught on the metal lips of the air handler cover doors. Installing a new filter is tricky due to the very tight clearances. Best bet is to get a separate 4" media filter cabinet and eliminate this problem. If you can't, try Goodman's washable filter as it may be sized to match. If you use the Goodman filter, let me know how it works for you as I may do the same. Best to you.

The units were probably registered. What happens though is that when the home changes ownership, the warranty reverts back to the standard warranty of 5 years. (Like it wasn't registered, even if it had been registered.) The A-coil of the electric furnace can be replaced in some cases. But if you attempt to order the exact coil from the manufacturer that coil made specifically for that air handler will likely be sold for more than what a whole air handler will cost you. Oh, those pesky manufacturers. Yep, they all do it. In some cases not all, I have been able to just change the coil many times with a different brand of coil that will fit the box of the air handler. The problem these days is that the coils are larger (more surface area) than those made just some 5 odd years ago. So there is probably a 50/50 chance that you could just change the coil and it fit right. Given that you just purchased the home, it's probably in your best interest to replace the system and upgrade the AC to use R410a refrigerant. R22 also widely referred to as Freon will no longer be produced after Dec. 31, 2019, what is allowed to be produced is a very low amount that will never come close to meeting demand. Because you have 3 systems that use R22, and you bought this home as opposed to looking to sell it... you will need to start converting these systems over to R410a refrigerant. This can only be done by replacing equipment. Refrigerant leaks will continue to be a challenge as the price of refrigerants continue to rise the old method of recharging systems every year is a thing of the past. Those leaks have to be repaired, regardless of the type of refrigerant your system uses. In addition to the complications listed above about changing only the coil, the units you have are heat pumps. So any coil that you attempt to change for this system would need to be a heat pump coil. Some coils are AC only without specific changes to the coil, the heat pump would never work right. This would be considered a high skill operation. It can be done in some situations... but should be left to those who have done it. If you can't find someone like me in your area... forget about it. Want to see why newer copper coils fail: it has nothing to do with brand. It has to do with the thickness of the copper wall. So aluminum coils are now the rage. Are all aluminum coils the most perfect thing since sliced bread? Watch the video: Copper Coils Vs Aluminum Coils. ( I service the Katy, Texas area a west suburb of Houston, Texas)
