I building a 2000 square foot metal building house. I’m stuck in choosing which A/C to go with. All electric. 18 Seer Trane or 20 Seer Amana? Both variable speed with no heat pump. Anybody have these systems? Spray foam insulation

From the same contractor?
Make sure they complete a manual j and manual d calc before sizing.
After that pick whichever one you like best. Both use almost all the same components. I would choose based on cost and warranty if it were me.
The biggest factor is the installer. A poor install by a bad contactor will make every brand suck.

Also verify the type of variable speed. The good ones use ecm blowers. There are some cheaper variable speed motors that aren't as efficient and not as good at holding CFMs.

I have the 18 SEER Trane with variable speed air handler. Super efficient and very quiet. Can't even hear it when its running. I'd definitely recommend it.

Yes from the same contractor. He has already did the load. He says Amana has better warranty and $900 cheaper

I had an amana system in my last house. No complaints about the equipment.

In addition to notsince98 comments, you might find comments in this thread on the HVAC-TALK forum helpful - just posted a couple days ago. All responses to the poster’s question are by professional HVAC techs. Thought it might be your post initially but looks like the poster is in VA

How do you feel about consumer reports ratings? Based on their maintenance and reliability surveys of Consumer Unions members Trane gets the highest rating in both predicted reliability (8/10 rating) and owner satisfaction (9/10 rating). Amana is #15 of 21 in predicted reliability(6/10 rating) and #17 of 21 in owner satisfaction (6/10 rating).
Those are brand rating so individual models may differ. Based on my personal experience with Trane, I think I’m likely to get that brand if I have to buy a new unit.

air quality is always an issue with spray foam so dont add to it with gas heat and carbon dioxide worries so go with electric heat. that also eliminates adding another hole in the building.
i always suggest for large houses they go with split systems so the bedrooms or upstairs have a separate unit from the rest of the house. it helps with the electric bill plus you always have "some" cooling if one system breaks on you

I talked to my A/C yesterday and he said go with the Trane because of the TAM9 air handler. He said Trane is in a league of its own with variable speed units. He is a big Amana dealer with lots of kickback from them. He said in my situation the Trane unit all day long

Since he will install it and service it, sounds like advice worth considering.

FWIW, my first unit when my house was built in 93 was a Trane, lasted 13 years and not once in those 13 years did I require a single service or repair call. Was replaced with a Tappan (Nordyne), but by the same company who installed the Trane, and until last July (another 13 years) when it was found to be 1 lb of refrigerant low, it also did not require a single repair call, and this past March the condenser fan motor bearing/bushing started to fail so I replaced the fan motor myself.
Anticipate a working life of 12-14 years until replacement. I’m at this age with my second unit so i anticipate replacing it in the next year or 2 max. Want to install some energy saving improvements to the home this year before replacing my system.

American Standard / Trane.. Same units,same model numbers, different colors. The proper install is the key. Don't cut corners and you should be fine..

I have the 18 SEER Trane with variable speed air handler. Super efficient and very quiet. Can't even hear it when its running. I'd definitely recommend it.
I have had the same, 5 years old this summer. Very quiet, very even temperature throughout the entire house and removes a lot of humidity. The lower electric bills
are a bonus.

Curious, do you have open cell foam insulation in your attic or traditional blown in or bat fiberglass insulation in attic?
Posted on 5/21/19 at 10:53 am to CrawDude
blown in. I did not build it, it was a builder spec.. I would have used spray foam, as this is my last house

Thanks and no problems (condensation, etc) associated with ductwork to date?
I ask b/c I’ll replace my 14 year old HVAC in the next year or 2 and I also have traditional blown in insulation in attic. I have quotes sitting on my desk for Trane single stage Seer 16 and variable speed Trane seer 18. I like the idea of the variable speed unit but have read that one must potentially aware of potential moisture issues in ductwork if all aspects of the duct work and air handler are not properly insulated in a “traditional” open ventilated attic (fiberglass insulation). Also I’m told that variable speed units can potentially more of an issue, condensation wise, for those who keep their AC at low temps, like 70 F or lower, because of the long run times associated with the variable speed units, reaching dew point in the attic, etc. Anyway, doing all my homework before I make my final decision.
I’m glad to hear your happy with your system. I like the idea of a variable speed system that is quiet. My single stage unit pretty loud but I’m so used to i don’t give it a second thought, but HVAC tech that provided me quotes asked if my current system was always that loud.

Spray foam in the attic really doesn't get you much.
The only applications I have found where spray foam makes the most sense is rim joists, basement walls, crawl spaces, anywhere that has moisture contact.
Walls and attics it really isn't the best option depending on your priorities.

I disagree. A attic with spray foam on roofline is 30 to 40 degrees cooler
Posted on 5/21/19 at 4:26 pm to Stellytiger
I did have one duct, closest to the unit, with condensation. They re-insulated the run. I have all metal duct and one flex
