Performed diagnostic on Trane air conditioning system, found high pressure switch and low pressure switch in outdoor unit tripped. Bypassed both to get unit to operate and found refrigerant metering device in the indoor unit is failing which caused both pressure switches to trip as a safety to prevent damage to the compressor. To fix all refrigerant needs to be removed from system, metering device would be replaced as well as a new liquid line filter drier, vacuumed out and then recharged

Diagnostic service on 2009 Day & Night furnace, system was blowing cold air only. High efficiency furnace had blockage in drain system and was causing the system to shut down. Cleaned and cleared drain line and furnace is now heating the home.
