Not cooling

It SHOULD NOT ... (smell in... even in WEST TEXAS).

BRAND NEW... Rush on down and get a good
NEW one.

I would suspect the condensate drip pan is plugged...

Common for AC units ..

But NEVER in "brand new"...

Get that (previously owned (my opinion)) UNIT
back from where you bought it ... Trade it in for a CLOSED BOX... and make your sales CLOWN write up why you are returning it.

Mold can be quite dangerous!!

Yes, be very very concerned. Get help. Don't use heater.

Hello, the coils can be cleaned with coil cleaner that is sold at any heating and cooling store, usually in a aerosol can. The inside of the AC can be cleaned with soap and water. They also sell a cleaner for mold at heating and cooling stores that can be used to get rid of the mold.

Mold can make you very ill depending on which type of mold it is. Mold forms in dark, wet environments and can be hard to get rid of. Your a/c unit needs taken apart and each piece that has mold will need to be cleaned thoroughly and carefully before re-installation.

The only thing that is vaguely related to fuel (which it's not) in your AC unit is R14 refrigerant gas. Under most circumstances, it's described as a sort of sweet smell. If that's what your smelling, it indicates the it's leaking either fro the compressor or the cooling coils. In which case, the unit will stop cooling pretty quickly.

With that said, it mat be a case of the odor is from another outside source and the unit is picking up the odor and circulating through the AC unit. Also, the air intake filter may need to be removed and cleaned and/or replaced. When you remove the filter, it may give you access to view the condensation pan and the cooling cool and heat disbursement (cooling) fins, which all may need cleaning.

If the condensation pan shows signs of mold or mildew. you can clean it with a bleach and water solution and then rinse it thoroughly. For the coils, use warm water and dish washing detergent. Use a vacuum with a hose and brush attachment to clean the cooling fins.

Check outside an take note of any fuel type odors, that the unit may be picking up.

Hope this helped you troubleshoot and solve the problem. Please let me know. Thanks.

As far as I'm concerned mold is always a potential problem with any humidifier. You can buy a cleaning solution at most hvac supply outlets that will keep this to a minimum and also smells good. If you want to do it for less money and don't mind the smell of chlorine then use 3-4 ounces monthly to control mold and bacteria growth. Thank you.

Make sure it isn't toxic mold. Neptunes are prone to mold. Maybe try to get a sample of the water in it when you run to take and have tested. Also, look closely at the gaskets and brush around the drum, they may have mold on them, like mine do.

THE SMELL MIGHT BE FROM MOLD DUE TO HUMIDITY COLLECTING INSIDE THE UNIT NORMALY THE GAS A A/C USES IS ODERLESS OR MIGHT BE FROM STAGNET WATER INSIDE THE UNIT.

does it smell like literally , dirty socks?if so it is dirty sock syndrome, a plague of heat pumps for years. if it smells like an electrical melting or burning of wires then time to call a pro.it could be a weak capacitor or a weak fan motor. if it is dirty sock syndrome then its the microbes that thrive when temps are middle temps and reproduce when temps are hot and cold in intermittent days. hot one day and cold the next equals call for cool then call for heat and hot steam from heated coils cause s bacteria to grow and microbes to spread across coil. when you switch back it causes the smell.if the coil is clean you can spend a chunk of money on sanitizers but best bet is to run it cool for hot weather and hot for cool weather. the transitional periods are what create the smell. avoid semi cool and semi hot periods. this condition is common to acs from all brands . lots of stuff on the internet about dirty sock syndrome

I have a maytag ac unit that kept smelling moldy. We tried spraying with antifungal, only helped for a short time. I took the unit (ac unit slides out of window case) outside and carefully removed screws only to discover the fan was covered in mold!!!! Oh my what a horrible discovery! I washed the fan blades with bleach and water mix. I completely and carefully washed and wiped down the air conditioner careful around the control box. Then I let the unit sit outside in the sun untill completel dry. Good bye mold and fresh clean cool ac!! I will do this each year now that I saw that ugly mold!! That is definetly a health hazard! I would reccommend you either thouroughly clean your unit or pay someone to do it or get a new unit right away!! Don't use that moldy unit another day!! Good Luck!
