Upon found main living room not cooling. Checked inside unit and found the filter completely clogged, and minor ice on coil. Removed filter and checked outdoor and found pressures low. Coil is 5 yrs old and condenser is 1 yr old. Called Lennox and they said the coil went out of warranty in February 2021. Homeowner wanted to move forward with the leak search, while performing leak search Denzel called and told me to stop due to homeowner wanting to find a better price to replace coil. Will still need to collect service fee and for leak search. Called homeowner and got no response for payment.
