I also treated the drain line. The filter for the furnace was replaced. No major issues were found, and the system is running at the completion of service.

Completed duct sealing. Sealed all buckets and returns to the drywall from the attic, with the exception of the laundry room, which was already sealed from the inside. Removed satellite plenum and installed sheet metal wyes to increase airflow. Ran new 8” flex duct. Removed wye going to bedrooms and made them into home runs to the supply plenum. Upsized bucket and sealed to the drywall. Verified drain operation.

Air Conditioning System Repairs: While troubleshooting a client’s AC unit, I found a clogged drain line causing water to back up into the system, threatening internal components. I cleared the clog and installed a float switch to prevent future overflows, ensuring the system would function smoothly throughout the autumn season.

Service diagnostic found that the condensate drain line was clogged. Water had backed up into the secondary drain line and tripped the safety switch. Options for repair were presented to the customer, and Mary chose to have the drain line cleared today. I cleared the drain line and tested the drain with two gallons of water. Clear water was observed flowing from the drain line outside the home. I then treated the drain. I function tested the system and the system is now operational.

Heating tune-up completed on a horizontal gas system. I did find that the inducer motor is slightly over amping and brought this to the attention of the homeowner. He is aware and will help us monitor. No other major issues found, and the system is heating properly at this time.

Performed diagnostic on the system and found that the blower motor has failed. I confirmed the motor is receiving a constant 24volts and 120volts from the furnace board. I presented my findings to the homeowner, and he chose to have the motor replaced and also have a surge protector installed on the furnace. I installed the motor and the surge protector at the furnace. I then cycled power at the thermostat. The total furnace static reading is .56 and the airflow is set to 1085 CFM on the 3-ton system. After checking the airflow, I wiped down the furnace as best as I could.

On arrival, the customer stated that the unit stopped working overnight. I began by checking the air filter, and then replaced it with a customer supplied filter. I then examined the evaporator coil and checked the float switch. I found that the float switch has tripped. Went outside to examine the condenser and found a faulty capacitor. Presented the customer with options for repair, and they chose to move forward with the items on the critical repair estimate. After replacing the capacitor, I vacuumed out, flushed and cleared the condensation drain line with CO2. Poured multiple gallons of water and was able to verify proper drainage before treating the drain line with Viper treatment. Cycled the system on cool mode to verify proper operation of unit. The system is cooling at this time.

Performed cooling maintenance on one heat pump system. Checked all electrical mechanical and performance of the system. Cleared and treated the drain line and washed the outdoor coil. I found the system does not have a water safety switch and there is some microbial growth at the air handler. I cleaned the microbial growth as best as I could. At the condenser I secured the compressor wiring to prevent any rub outs. The condenser fan motor is also showing signs of overheating. No other major issues found.

Duct Air Purifier Installation: Installed duct air purifiers to reduce pollutants and improve indoor air quality with advanced purification technology.

Single system cooling maintenance completed on a horizontal gas system. Indoor unit, fan and evaporator coil are clean. The drain line flushed and treated. The float switch was tested and is operational. Also replaced 4" media filter. The outdoor coils are clean, all electrical within manufacture specs and the refrigerant charge is within range. No major issues found.

Cool check completed on an up-flow air handler and condenser. The drain line has been cleared and treated. The float switch was checked and is working properly. The evaporator coil has significant buildup and I highly recommended it be cleaned in place. The condenser coils have been cleaned. All electrical is within manufactures specs. No other major issues found, and the system is cooling to the best of its ability at time of departure.

Performed AC cool check. Checked electrical, mechanical, safety, and performance of the system. The drain line was cleared and treated. The filter was replaced with a customer supplied filter. The blower wheel is clean. The wiring is tight and in good condition. The secondary drain line is piped in a way that would allow water to back flow into the secondary pan. The condenser fan motor and contactor are both in good condition. The condenser capacitor is within value. The refrigerant charge is within spec, and the condenser coil was cleaned. Options to upgrade the drain line and install a second safety switch were presented to the customer, and homeowner chose to have the safety switch installed. I added a safety switch to the secondary drain line so that water will trip the switch before it flows into the secondary pan. The system was function checked and is running at the time of departure.

AC Refrigerant Leak Repair: Fixed a refrigerant leak and recharged the AC system to restore its cooling capacity and efficiency.

AC Expansion Valve Adjustment: Adjusted a faulty expansion valve to optimize the AC system's cooling performance.

Cool check completed on a horizontal gas system. Cleared and treated the drain line. Checked the float switch and it is operational. The blower wheel is clean.
