Came out on call back for nasty smell coming out of supplies around the house. Checked coil checked filter checked duct work inspected blower wheel Found nothing dirty or wrong. Customer states it's a clorox smell and stated that they pour clorox down the drain yr round even in winter months when drain line isn't having condensation go through it. Customer has quote from Jeremy for uv light and coil cleaning. Customer is going to try and run a.c. more to create condensation to try and help flush the drain line at this time also will for now on use white vinegar when do maintenance/change the filter
