Performed Precision Air Conditioning Tune Up on System. Replaced the High Efficiency 401 Filter. The Condensation Pump was an old style Pump. These pumps have had issues with the motors failing, and their is no safety device to shut the system down. Recommended and installed a new 115V Condensation Pump with an internal safety. If the Pump fails to discharge the water and the tank fills, it will trip the internal switch and shut the 24V power off to the system. Filled Pump and tested operation. Tested safety switch on Pump to ensure it would shut the system down. Inspected Electrical Components on the Indoor and Outdoor Units. Measured Refrigerant Charge on system.While System is operating, and Refrigerant levels are to standards at this time, the system is about 18 Years old. Due to age of System, it is recommended to begin planning/saving for replacement of the Gas Furnace/AC.Showed Homeowner how to remove and reinstall filter on Dehumidifier in Crawl Space.

Performed Precision Air Conditioning Tune Ups on the First and Second Floor Lennox Systems. Replaced 16x25x1 Air Filters provided by Homeowner. Closed Humidifier Damper and turned Humidistat Control off. Inspected Electrical Components on Indoor and Outdoor Units. Clean AC Coil Drain Line and Condensation Pumps. Due to the way the Drains were piped into the Condensation Pumps the base of the Pumps cannot be removed to clean properly. Recommend installing Unions onto Drain Pipes for both Systems to allow full access to the Condensation Pumps. Also recommend installing EZ Traps onto both AC Coil Drain Lines. Measured Refrigerant Charge on both Units. Both systems were cooling but the Refrigerant Pressures were slightly off with higher than recommended Superheat Levels. Calculated Line set lengths which both exceed the Refrigerant lengths that the manufacturer accounts for. Recommend adding Refrigerant to both Systems Charging by Superheat.

Turned system on and observed operation. Measured air temperatures at 107 degf at plenum after 2-3 minutes of run time which is satisfactory. Thermostat set point was at 72 degf and room temperature measured was at 72 degf. Unit is maintaining temperature. It is normal for air temperatures coming out of registers to be cooler when unit starts up because it is a heat pump system.
