Dunn NC Heating & Air Conditioning Services

Tech found system design is very typical for a mobile home application. Tech verified airflow is not bypassing the coil. Tech inspected ductwork. Tech also tested pressures and found no issues. Normal head pressure in heat mode and normal superheat in AC indicates proper airflow across the coils. Customer recently had work done from another company that stated the coil was open and filters were place on top of the coils. Tech explained that this is also typical of a mobile home furnace and would not cause any airflow issues.

- Tech measured relative humidity in crawl space reading 55.8%, inspected ductwork and foundation vents. No signs up moisture accumulation and all ducts are suspended and in working condition.

Upon arrival tech found Goodman system in right building reading 77 degrees inside but set to 73 degrees. Initially checked filters and found both filters extremely dirty restricting air flow. Replace with new 2- 20x20x1 pleated filters and checked Delta T at 18.3. Indoor temperature began dropping after replacing filters. Inspected indoor system and coil was not frozen. Upon departure indoor temperature had gotten to 73 and cut off. Tech recommends they check filters weekly or every other week due to just having new ones installed a month ago and were already extremely dirty to avoid issues. Tech was informed by worker that system was frozen up but they cut it off before we came, which was due to filters. System is back operational at this time.

On arrival, for left building Carrier R22 split system, customer reported no airflow out of vents. Tech noticed outdoor fan running, but not compressor. Compressor is very hot to the touch. Tech confirmed overheated compressor. Shut off outdoor disconnect and inspected AHU. Tech found 5 speed X13 ECM blower motor rocking back and forth, but not starting. Tech confirmed line and low voltage to blower. Tried all 5 speed taps. Blower will not run. Per service history, we have found indoor coil to be leaking R22 refrigerant in the past.
