Today we performed a commercial maintenance on all twelve of your systems (7 Tranes, 1 Lennox, and 4 Goodman’s) . We changed all filters (5-12X12X1, 2-20X25X1, 2-20X20X1, 1-18X24X1, and 1-12X20X1) cleared and treated all primary drain lines and drain pans, and checked amperages on all systems. Everything is working properly at this time. Thank you for your business. Thomasville Ga
