-Performed CMA Full Service on 4 Split System Heat Pumps. Performed operation inspection on 3 Exhaust Fans and 3 Hanging Heaters. -System 4 is over 25 years old, uses R22 refrigerant, and was found to have an evaporator coil in poor condition prior. System has been recommended for replacement, but was servicing a space not in use. System currently is set at a cooling temperature and is working correctly. -Found all equipment working as expected. Staff declines any proposal for replacement of System 4, intends to run system until it fails and reassess needs at that time. -Observed heavy ant intrusion at outdoor condensers. This could potentially lead to challenges with condenser electrical components. Recommend area around condensers be treated.
