I performed cooling maintenance today on an AC pro system. Upon arrival, the system was fully operational. All electrical components tested in the ranges with no signs of damage, including the compressor and fan motors. The system features surge protection and air purification! I cleaned the outdoor coil as it was dirty and replace the return air filter with a customer provided filter. Upon departure system was operational and cooling mode with an optimal temperature differential. Thank you for choosing a Cool Air Solutions and renewing your Comfort Club membership!
