For this cooling tune up I inspected the furnace and condenser. For the most part everything was measuring with a manufacturer specs and running well. The drain lines did not have any vents as required for proper ventilation and to prevent sewage gases from entering the home. I formed the customer that the events were needed, as well as how slow the drain line was draining that there was a potential for a clog or clogged developing. I filled out the drain form as she did not want to get it fixed and that she would think about it. I recommended a IQ 200, because she has a UV system however it is old and the bulb is out. Additionally I recommend a compressor saver, surge protection, low voltage wiring insulation, and lastly a drain line repair. Customer said she would think about it and get back to us if she decided to move forward with the repairs.
