Annual HVAC tune-up and safety inspection. Cleaned and serviced the condensing unit. Tested all mechanical parts drain line. Checked refrigerant levels. Everything is in accurate working condition. The system is operating and cooling as it should be. Noticed the 15-year-old water heater is leaking into the drain pan. Giving customer estimates for a new electric short 40-gal water heater. With his unit on the 3rd floor, this needed to be addressed immediately.
