Service call that the Second System for the Home was freezing up on the Indoor Coil. Inspected Indoor Coil to ensure that it was clean and free of debris. Poured Water Through Drain Pan to ensure that it was draining and not clogged. Drain Line was clear and condensation Pump was operating. Checked Blower Wheel and checked Fan Speed for Cooling which is set to High. Tested the Blower Capacitor which was rated for 5 Mfd but was testing very low at 1.3 Mfd. Also found the Fan - G Wire on the Control Board was loose. It appeared to still be making a connection, but the Terminal Screw was not tightened on it. Stripped wire and tightened into G Terminal. Replaced Blower Motor Capacitor and tested operation. Measured Refrigerant Charge on system. Refrigerant Pressures were slightly lower than normal, but Return Temperature was at 64 Degrees. The Blower Motor May have been not running properly due to the Low Capacitor. The Blower Motor May have been running intermittently or starting and sto
Service call that the Air Conditioner which supplies the main part of the Home was not Cooling, and the Indoor Coil was freezing up. The System which supplies the Addition to the Home was working but some frost was noted on the Outside Lineset. Turned the Addition System on and tested operation. Measured Refrigerant Charge on Unit. Refrigerant levels were to standards. Checked Capacitor on Outdoor Unit and Checked Air Filter. Supply Air Temperature was at 49 Degrees and Return Air was at 69 Degrees. Proceeded to the system for the Main Part of the Home. Turned System on and measured Refrigerant Charge. Found system was low on Refrigerant. Added 3lbs of R-22 Refrigerant to System. System was producing a 10 Degree Supply versus Return Temperature Split and upon adding Refrigerant the Supply Temperature lowered to 55 Degrees with a 75 Degree Return Temperature. The Main Home System is from 1987. Due to age of system, and condition of losing Refrigerant, Recommend replacement of the AC
Performed Precision AC Tune Up on System. Checked 16x20x1 Air Filter. Cleaned Condensation Drain Line and Condensation Pump. Condensation Pump is cracked on the basin. This could leak as the pump fills with Water. Spoke with Homeowner about issue who is going to replace the pump himself. While testing the electrical Components, found the Dual Capacitor on the Outdoor Unit was testing below rating. Replaced the Dual 45/7.5 Mfd Capacitor and tested operation. Measured Refrigerant Charge on system. Refrigerant Pressure were fluctuating while the system was running. If the system was not properly installed and contaminants and/or moisture are in the system it would cause this fluctuation in Pressure. The system also appeared to be low on Refrigerant. If there is a leak in the system moisture and contaminants could be getting in. System is cooling but the Supply Temperature fluctuates about 5 Degrees +/- as the Refrigerant pressures fluctuate.
Performed Precision Heating Tune Up on Ducane Gas Fired Furnace. Replaced the 16x20x1 Pleated Air Filter which was dirty. Recommend checking Air Filters every 30 Days and changing as necessary. Inspected Electrical Components on the Furnace. Inspected Burner Assembly and Heat Exchanger which both appeared to be in good condition with almost no rust present. Found corrosion buildup in the Pressure Switch Tubing. Cleaned Tubing and excercised Switch to test. Performed Combustion Analysis on Furnace while measuring Supply/Return Air Temperatures.
Performed Precision Air Conditioning Tune Up on system. Replaced 16x20x1 Air Filter. Recommend checking Air Filter every 30-60 Days and change as necessary. Found Condensation Pump base was cracked and broken. Showed Homeowner the Pump. Homeowner is going to purchase a new Pump and install. The current Condensation Pump is going to leak when it begins to fill with water due to the crack. Need to replaced Immediately. Tested Electrical Components on the Indoor and Outdoor Units. Dual Capacitor on the Outdoor Unit is measuring below rating. Recommend replacement of the Capacitor. Measured Refirgerant Charge on system. Included an estimate for the pricing of the Dual Capacitor.
Service Call that the Air Conditioner was not working. Upon arrival, found that the Outdoor Unit would run but the Indoor Unit was not operating. After troubleshooting, determined that the Blower Fan Motor had failed and was seized. Exact specifications of the Blower Motor could not be determined without complete removal of the Motor from the Blower Wheel and Harness do to the positioning of the label with the Motor Harness. Due to the age and poor condition of the system recommended replacement of the system instead of repair of the Blower Motor. Turned the system off at the switch on the Furnace. This system supplies the Main part of the Home. The office will contact to schedule a time for Joe to come out to present Replacement Options.
Performed Precision Air Conditioning Tune Up on system. Replaced 16x20x1 Air Filter. Cleaned Condensation Pump and Drain Line. Tested Operation of Pump. Measured Refrigerant Levels of system. While testing Components, found Indoor Blower Motor Capacitor was testing low. Also found Dual Capacitor on the Outdoor Unit was testing at its highest rating, and the Contactor was very worn and pitted. Install a new 15 Mfd Blower Capacitor, a 45/7.5 Dual Capacitor, and a Single Pole 40 Amp Contactor. Test operation of system upon completion. System is only running at about a 15-16 Degree Temperature Differential in Air Conditioning. Due to Efficiency of system and age, recommend begin planning for replacement.
