Gas company didn’t show up
Looked at water heater. It is failed and we will replace it with a small electric tank. We'll send Joey a price.
Replace the blower motor that serves AHU-2 with matched motor.
Flush Rinnai
Need to come back with compressor and trace propane line
Had to adjust blower motor speed for heat. Everything works great! There should be make up air added to the room for the required combustion air. If you go with a direct vent system it will not be an issue!
The boiler is on and makes heat and hot water. However the 4000 hour maintenance needs to be completed, I did not have the kit on me. I made an estimate to complete a 4000 hour maintenance on the boiler. This price only covers the service of the boiler with the maintenance kit. The estimate price does not include other potential parts/ components that may need to be replaced.
Everything with the maintenance on your Bryant natural gas furnace and Rinnai tankless on demand water heater went great! We also changed the humidifier pad in your Aprilaire bypass humidifier. When we went to put the humidifier into test mode the water solenoid would not turn on. I diagnosed the humidistat as being failed. I checked the warranty and it is a 5 year warranty so we will order one!

Dedicated supply registers will be installed for each room: the bathroom, bedroom, open living/bar area, and unfinished storage room. A dedicated return will be installed in the bedroom and unfinished storage room to promote proper airflow. A main wall return register will be installed in the furnace room to circulate air from the open living/bar area. All registers, except the main wall return, will be ceiling-installed. The dehumidifier will be relocated to the unfinished storage room. The unit will be tucked in the back corner, so it does not need to be moved again if the room is finished. Main trunk lines will be 10x8 and 12x8 (please add a 1-2" factor for insulation). They will be tucked against and as close as possible to the existing first-floor trunk to allow for minimal boxing in of the finished ceiling. The

Performed a comprehensive AC maintenance in Manchester. Giving the client optimal system performance. Inspected the condenser coils for debris, cleaned and adjusted the fan belts for proper tension, and verified the refrigerant levels to ensure efficient cooling. Checked the thermostat calibration and ensured the evaporator coils were free of obstructions. All electrical connections were tightened to avoid future issues. The system is now running efficiently, ready to handle the demands of the season. Maintenance complete, and the unit is performing as expected.
The system needs refrigerant added to it. Low pressures and low temperature difference between the supply and return air.
Performed routine maintenance on a Bradford White RG250T6N 50-gallon natural gas water heater in Manchester, NH. Drained the tank to remove sediment buildup, inspected the magnesium anode rod for signs of corrosion, and replaced it with a new one. Checked the Honeywell gas valve/thermostat to ensure it was set correctly and functioning efficiently. Verified the operation of the T&P relief valve and flushed the system to ensure optimal performance. The water heater is now in peak condition and ready for continued use.
Upon arrival, the drain pan was completely full of water in the living room mini split. I took apart the housing and I disconnected the drain line. I found that the line going through the wall was completely plugged up so the water was backing up. I cleaned the drain line with green drain cleaner. I ran a lot of water through the drain pan and there was no backing up anymore. I recommended to the client that he should have everything maintenance. I cleaned both coils with Dawn soap and water. I cleaned the filters as well with Dawn and water. I then went outside and cleaned the outdoor unit with water. I rinsed the outside of the unit with soap and water. I checked all electrical connections and everything was good. I did an overall system pressure check and everything was perfect.
Diagnose fan coil 003 on a commercial hvac unit. We will send Bill a quote to replace them.
