Called out today to perform a precision tune up on two units. Checked all electronics and motor components to ensure equipment is operating properly within manufacture specifications. Checked filter and cleared drain line/pan. Measured the temperature drop across the coils. Outside I removed the fan from the condensers and cleaned the coils from the inside out. Vacuumed drain lines clear from outside port. Equipment is operating properly at this time. Unit #2 is extremely hard to access due to the hanging brackets. There is one visit remaining on this year’s maintenance agreement. Performed a drain solve treatment to both units due to algae build up within the lines. Thank you for always choosing Total Air!
