Humidifier Repair

Great experience. Efficient, prompt, friendly and flexible with timing. Chris did a great job and fixed my humidifier in an hour when two other technicians (from different companies) were unable to do so.

Service call that the Air Handler/AC system which supplies the Breakfast Area was not working. Upon arrival found system was turned off. Turned System on to test Operation. Found Blower Motor was seized and would not operate. Also found Blower Wheel fins are completely covered in dust and soot from the construction that took place in the room. The Blower Motor needs to be replaced before the system can be fully tested. While the Motor is apart there is more access to clean the Blower Wheel. Removed Blower Assembly and Blower Wheel Assembly. Removed the failed Motor and dry cleaned the Blower Wheel and Housing. Installed a new 1/3 HP 1075 RPM Blower Motor with new Capacitor. Installed Blower Assembly into the Air Handler. Wired Blower and Capacitor. Installed a new 20x20x Air Filter. Restored power to the system and tested operation. Measured Supply Temperature at 48 Degrees with a 66 Degree Return Air Temperature. The Outdoor Unit has a Low Ambient Switch Installed which causes the O

Checked no cooling on new air conditioner, found no call to Y only the Blower comes on, found an open Y wire from the thermostat to a splice and to the furnace. Temporarily jumped Y and G at the splice to run cooling. A wireless thermostat or 2 or 3 wired thermostats are the only option without trying to pull a new thermostat wire to the second floor. I explained that they can not run the fan in the on position only auto until thermostat wire issue is fixed.

Performed Precision AC Tune Up on Rheem System. Replaced 16x25x1 Air Filter. Cleaned Condensation Pump and Drain Line. Filled Pump and tested operation. While testing Electrical Components, found Outdoor Capacitor testing below rating. Also found Contactor was very worn and pitted. Recommend replacement of the Contactor and Capacitor. While measuring Refrigerant Charge, found system to be low on Refrigerant. While System is running and cooling now, during high heat/humidity days the system may have difficulty maintaining temperature in the house. System is about 19 Years old and is running inefficiently. Due to age, condition, and recommended repairs replacement of the Furnace/AC system may be advised. Also found Hot Water Heater to be about 20 Years old. Average life of Water Heaters is between 10-12 Years. Recommend replacement of the 50 Gallon Power-Vented Water Heater before any issues arise, or failure occurs.

Homeowner was informed from Pest Control Technician earlier today that the Insulation in the Crawl Space was falling down. Inspected Crawl Space area and found Insulation across the entire crawl space was torn and fallen. Insulation appears to be in poor condition. Referred homeowner to GreenSky Energy if she is interested in repairing/replacing Insulation. Due to issue the previous day with the Mini Splits not turning on, tested units to ensure they were working properly. No issues at this time.

We added 2lbs and 9oz of r410 refrigerant to the system checked in heating and cooling mode all systems were good! Also installed surge protector on disconnect.. before leaving I had 48. Degree supply and 70.1 return air.

Performed Quality Assurance On Daikin Mini-Split System. Homeowner was concerned that when she tried to use the one Unit the indicator light was flashing. When I tried to turn both units on in AC Mode the Indicator Lights flashed but the Units did not operate. While I was checking over the system I unplugged the Disconnect and then plugged it back in. After this the Units began to operate, but I cleared any possible error codes that were stored on the remotes. Cycled both Heads multiple times but was not able to recreate the Error. Informed Homeowner that if issue occurs again to call us and leave units in that state. Checked Wiring on Outdoor Unit to ensure the Indoor Units were wired to the proper A and B Terminals.

Performed Precision AC Tune Up on system. Replaced 16x25x1 Air Filter provided by Homeowner. While inspecting Electrical Components on System found Blower Motor Capacitor was testing below its rating. Recommend replacement of the 5 Mfd Blower Motor Capacitor. Also found the two Capacitors on the Outdoor Unit were testing within ratings, but are corroded and rusted. Would recommend replacement of the 35 Mfd and 5 Mfd Capacitor for the Outdoor Unit. While testing system, found the Outdoor Fan Motor would start at a slow speed and then would increase to its normal operating speed. The Fan slowed down during operation momentarily and then increased back to normal speed. This is indicating that the Fan Motor is starting to wear and could fail. Manufacturer and exact age of the AC system are unknown, but it is estimated to be about 20-25 Years old. Would recommend replacement of the Furnace/AC system due to age and condition. Spoke with Homeowner about recommendations for repairs/replacemen
