Luis 8-25-26 Customer called in for no cooling Bryant ac unit from 4/20/2016 Two zone system both thermostats in the off position upon arrival turn first floor thermostat to cooling. I heard the outside unit came on, but then after seconds it shut off. Check indoor unit blower runs. I inspect indoor coil there seems to be refrigerant oil around coils and drain pan. I checked outside unit found refrigerant pressures very low. I tested refrigerant system. there's a restriction in the line (like a stuck expansion valve or debris in the filter drier). The compressor is working twice as hard to push refrigerant through, but key parts of the system are getting starved. That's why the system isn't cooling properly. Because of that pressure buildup—or simply from normal wear and tear on the coils-i also suspect a slow leak. A sealed system should never lose refrigerant. If the charge is low, it means gas is escaping. If I clear the blockage, repair the leak, pull a vacuum, and recharge the s

Luis 8-18-26 Tenant called in for noise coming from steam boiler. Talked to tenant upon arrival, they described as if the boiler was low on water, I flush water to test low water cutoff and water feeder system, water came out dirty. Test operation of low water cutoff/feeder ok. No issues found. Have a feeling water levels was low or sensor was not reading water level correctly due to dirty water. No issues found.
