Upon Arrival found system calling for cooling but no air flow. Went on roof and found package unit frozen up due to very dirty restrictive air filters. Pulled filters and let unit dethaw. Went through other systems and washed mini split filters and replaced 1(20x30x1. After system dethawed went thru all electrical components. Checked amp draws. Checked pressure/temps superheat/subcooling on refrigeration system. Replaced all 6(18x18x2) return air filters in package unit. Highly recommend a Service Club Membership so that way we can come out and replace filters and go through system with a fine too the comb to prevent premature failures also to extend life of equipment and save money on energy costs every year. 3 year 24 hour service every 6 months on three pieces of equipment (AC/Heat). $1,152.00 3 year 24 hour service every 3 months on three pieces of equipment (AC/Heat). $2,304.00 For waiting room I will talk to Andrew about a mini-split AC/Heat for that conditioned space.
