Bad smell from ac unit in my house

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

You have DSS. When was the unit installed? Have you contacted the installing contractor? Have you told him what it is? Did you get a parts and labor warranty with the unit? Best solution is a new coil, get it coated and ask the contactor and manufacturer to foot the bill.
