Service call that the Heat was not working properly. Upon arriving onsite, spoke with Homeowner about issue. Was informed that the Heat had stopped working the previous day and then was working again. Temperature was at Setpoint of 72 Degrees. Turned Temperature up at Thermostat to test system. After running for several minutes, the Blower Motor would begin to seize Up and and stop working. Cycldmthe System several times to test for proper Voltage and Measure Amp Readings. Blower Motor would seize up intermittently during testing. Also found Washable filter was excessively dirty. Installed a 24x24x1 Air Filter which was the closest Fit to the Washable Filter. Heat Pump System is very old, and is estimated to be over 30 years old. Due to very old age of system, and current condition of the Blower Motor, recommend replacement of the System rather than repair. The Heat is operating but the Blower Motor may continue to have issues.A Comfort Consultant has been scheduled for today.

Had previously been onsite for a No Heat Call. During this visit we had found the system to be slightly low on Refrigerant causing it to not Heat properly and to begin freezing up at the Outdoor Unit. Refrigerant and leak Dye had been added to the system at that time. Returned to site to perform a leak search using a UV Light and UV Glasses. Inspected the Indoor Coil and Outdoor Coil using the UV Light and Glasses. Inspected all accessible fittings on the Refrigerant lines. Inspected King Valves and Shraeder Valves on the Outdoor Unit. At this time, was unable to find any evidence of a leak point in the system. No UV Dye was detected and no signs of Oil were found while checking over the system. Homeowner informed me that the system has been operating without any issues. Due to the amount of Refrigerant that was added, the leak may be very small. Recommendation moving forward, unless further issues occur, is to continue to monitor the system and as we perform Future Maintenances we wi

Heat pump sent w call back and energized strip heat at 62 amps , all working fine , at this point it looks like the heat pump possibly might have not been able to keep up. Told Dave to keep an eye on it and call us right away if it happens again and take pictures.

Checked thermostat settings and found to be set to 5 cph for heating cycle rate. Unit was not short cycling on limit while on site, raised temperature from 66 to 75 degf and unit did not cycle off. Limit set for 140-30. Need to check with manufacturer to see. If proper limit is installed.

Service call that the aheat was not working. Upon arrival, spoke with the Homeowner about issue. Found that the Outdoor Unit was frozen. Homeowner informed me that the Electric Heat was running but was not blowing Hot Air. Proceeded to the Attic to troubleshoot the system. System was on,y producing about 10 Degrees of Heat and when tested, only one of the 5kw Elements on the 15 kw Heat Kit were operating. Further Diagnostic revealed that the other two elements had failed. Turned System into Heat Mode to allow the Outdoor Unit to run. Forced system into Defrost to test. System would Switch over to a Defrost but would not stay in Defrost for more than several minutes. Recommend replacement of the Defrost Control Board and Defrost Sensor.Ordered new 15kw Heat Kit, Defrost Board, and Defrost Sensor which will arrive tomorrow.

Performed Precision Heating Tune Up on system. Homeowner informed me upon arrival that there was an odor present coming from the system. She also said that the Second Floor was not getting warm and the Basement was very warm.Performed Tune Up procedure to assess performance of the Furnace. The Air Filter was dirty and needed to be replaced. Installed a new 16x25x1 Air Filter. Cleaned Furnace Drain Pipes and Condensation Pump. Inspected Heat Exchanger and Burner Assembly. Performed Combustion Analysis on Furnace to test Operation. While testing system Zones 1 and 2 were calling for Heat. The Zone Damper for Zone 1 was remaining closed. When Zone 2 Damper Closed the Air was not moving and creating excessively high Supply Temperatures. This was also forcing Air out of the Duct Work in areas that were not completely sealed which was causing the Warmer temperature in the Basement. After several attempts was manually able to open the Zone 1 Damper.The Damper for Zone 1 was stuck Closed

When first starting system found system freezing up quickly and pressures were 276/57. Suggested to home owner that we needed to perform a test by addding 1 lb of refrigerant to determine if issue was a restriction,or a slight loss of charge. We also explained to home owner that we could add leak dye and return around 30 days or at our next service. Also to note after adding charge found system pressures to be much better and delta t to be around 26.added leak dye to system, we will come back around 30 days to further diagnose.
