Low Batteries on Thermostat

Check your thermostat batteries! Actually just change them every year. Everything looked like it was working but it wasn't. Kurt replaced the batteries and all was well ... and still is almost a month later. He also measured the heat output via air flow and heat rise and it was a bit more than the unit is rated for. All good results. Also, not all the HVAC guys know how nor have the equipment to do this measurement. I was pleased.

Heat pump problem, same problem as last time we were here, high pressure code in communicated system, found exposed high pressure wire making contact customer copper, fixed wire and check heat pump operation ok pressure 320/80 cycle heat pump ok check airflow 1300 cfm

Performed heat pump check up check electrical low and high ok replace filter check and test electric back up ok check split ok, check outdoor unit capacitor and contactor ok test defrost check 410 pressures ok outdoor temp is 23F 280/60 cycle unit ok would recommend ac renew additive to lubricate internal parts from compressor, and also all valves, this will help reduce noise and all internal moving parts(txv,reversing valve, and compressor) will be lubricated

Service call that the Heat was not working. Upon arrival found Indoor Temperature at 60 Degrees with the Thermostat calling for heat. Found all Zones calling for Heat but the Furnace was not running. The Blower Motor was drawing amps and trying to run but could not start due to the Blower Capacitor rating being very low. The 16x25x1 Air Filter was very dirty and was blocking Air Flow. This lack of Air Flow will strain the Blower Motor and cause it to draw more power. Received approval for repair and Replaced Blower Motor capacitor. Installed a new 16x25x1 Air Filter. Inspected Flame Sensor and put system back in operation. Cycled system to ensure it was firing properly. The Exhaust Vent Piping is leaking at the Transition Fitting at the Furnace. Due to being glued, the Transition Pipe at the Inducer Motor would have to be replaced and a new Section of new 2” PVC venting installed. Exhaust is rusting the outside of the furnace cabinet and into the Blower Cabinet Base. Included estim

Found system reset, but homeowner had taken a picture of the code it was a high pressure lockout code. Found dirty 20x20x1 air filter, replaced with one homeowner had and tested out system. Hooked up gauges and found pressures to be within specks 274/72 410a at outside temp of 30 degrees. System also went through defrost when I was on site. Did no see any further issue at time of service.

Performed 6 month inspection on amana heatpump. Found on the service sheet that the air filter should be a 20x24x1. Checked all electrical conections and components. Checked refrigerant pressures and temperatures at indoor and outdoor units. Also found in floor loop was air locked , purged out small amount of air now loop is hot, and pressure is around 30 psi. System is working fine at time of service.

Found that from water pressure being to high it had damaged the pressure relief valve on the water heater also. Valve is very corroded. Had pressure relief valve on the truck , replaced and re- checked water pressure. It was at 55 psi.

Removed line and found no water coming out of saddle valve. Found broken saddle valve. Replaced saddle valve and tested humidifier, humidifier is working fine again, had no leaks. Talked to homeowner about valve, told him the less he opens and closes valve the better, this can break the valve.

When I arrived found that thermostat was just saying “humidifer pad” which is just a reminder. Explained to homeowner that the thermostat setting is on a timer and this just comes up after a a set period of time. Showed homeowner how to reset.

Performed precision heat tune up on trane gas furnace. 16x25x1 air filter is clean. Checked all electrical conections and components. Cleaned flame sensor. Checked gas pressure and performed combustion test. Also recommended replacing 50 gallon hot water heater due to age. Homeowner is interested in 75 gallon water heater. Also did a water test and found waterto be 9 grains hard. Recommend water softer. Gas furnace tested out fine at time of service. 1/10/20. Replaced both water feed tubes and cleaned both humidifier trays and installed new Aprilaire #35 pads.

Had Joseph turn on thermostat to heat pump. ( this heat pump is the heat pump with the service plan) heat pump came on . Compressor is starting to sound rough on this heat pump. Running amps are 8.2. 40/5 mf cap tested at 41/5.10 mf. Readings are good. Checked refrigerant pressures they were fine. Had a 31 degree temperature rise . Calculated the btu out put had around 33,000 btu,s very good. Only thing we noticed was thermostat was a little dim when I went up to adjust temperature. Found no c terminal on this thermostat. Replaced batteries with ones he provided. Recommend any more issues to replace this thermostat. Joesph said he would take care of this.

Checked water leak, found water heater pressure temperature relief valve leaking. Checked water pressure, to house, getting 80 psi. Checked expansion tank it has failed. Checked pressure reducing valve, valve is failed. Tried to lower pressure and pressure continues to climb. Need to replace pressure reducing valve and t-5 expansion tank. 12/23/19. Installed new pressure reducing valve and expansion tank. Checked water pressure at the bottom of water heater. Standing pressure was 53 psi. After water heater heated for a little bit pressure only went up around 65 psi. Pressure seems to be stable now and is working fine.

Checked over outdoor heatpump. Refrigerant pressures were 354/79 410a at 25 degrees outside temp. Checked capacitor readings they were 48/5.29. Capacitor is a 45/5 mf capacitor. Also checked to make sure electrical conections were tight at outdoor heat pump. Also put system through defrost mode , system does not need any refrigerant at time of service.
