A few months ago I thouroughly cleaned both coils of each AC unit which resulted in clean, fresh air from the units. However, over the past 6 weeks or so with humidity levels in mid 80's to 100% range on most days, upon initial startup, I have noticed a slight musty smell. Evaporator coil on each unit appears clean. So my question is, does anyone have knowledge of a coil cleaner that I could spray on the coils for maintenance that might kill any mildew / mold and restore clean fresh air? Any input would be appreciated.
Most box stores sell evaporator cleaner. Do not use condenser cleaner-- it is meant for outdoor use only.
And, yes, sadly with high humidity and the "less than effective" filters, these things do need periodic cleaning.
Thanks Brett,
I found a foaming cleaner at Home Depot that worked very well but required rinsing with water. Since coils are visibly clean was hoping to find something I could just spray on that would kill the mildew. But I'm always looking for that big "easy" button...maybe not this time?
Bill,
Here are some evaporator cleaner products from a company whose reputation has been earned by HVAC professionals.
Evap-Fresh No Rinse (http://www.nucalgon.com/products/coil-cleaners/evaporator-cleaners/evap-fresh-no-rinse-1)
Bio-Fresh cd (http://www.nucalgon.com/products/iaq/bio-fresh-cd)
good luck,
Thanks Rick!
Both of those products are just what I'm looking for. I will get one or the other tomorrow, or order, and give it a try. Grainger carries that product so should be able to get quickly.
