Performed precision a/c tune up on Goodman a/c system. 20x20x1 air filter is clean. Checked all electrical conections and components. Checked temperature split at indoor unit. Found system about 3lbs low on charge. Gave homeowner option to replace the system or charge with refrigerant. Homeowner decided to charge system with 410a. Added 3 lbs to the system. We donâ€™t know how long charge will last. Also fins are smashed on outdoor coil. Also found water heater to be about 13 years old highly recommended replacing water heater due to age provided estimate to replace. Tested outdoor capacitor. Checked temperature split. A/c is working at time of service. Found system about 3lbs low on 410a refrigerant
Performed precision heat tune up on (4) carrier air handlers with hot water coils. Replaced (1) 16x20x4 air filter. Replaced (1) 20x20x4 air filter. (1) 16x20x4 air filter is clean. Cleaned (1) wasable filter. Replaced (1) Aprilaire #10 humidifier pad. Checked other humidifiers. Tested condensation pumps. Checked dehumidifier. Set up thermostats date time. Checked humidity setting. Systems are working fine at time of inspection, no further recommendations.
System had 0 degree temperature split when I arrived. Charged unit using superheat method 5#. Final superheat 16.8 indoor wet bulb 62 outdoor dry bulb 70. 17F temperature split. Had conversation with Mrs. Worth about the value of setting up a comfort consultation appt to discuss replacement options. She is using a window unit to cool b2nd floor. System is operating well at the time of this tune up.
Installed a new Aprilaire 1850 Freestanding Dehumidifier. Removed old dehumidifier to take back to manufacturer for Warranty. Installed new Dehumidifier is same location by Sump pump. Adjusted feet to properly level unit. Installed drain line with new Vinyl Tubing to Sump pump. Went through setup programming on unit and Installer Test. Turned system on and put into operation. After Air Sampling Humidity Levels were at 64%. Set unit to 50% Humidity. Reviewed operation with homeowner upon completion. Unit had pulled down to 62% and was draining upon completion.
Performed Heating Tune Up on the 3 Systems for the First Floor and the 4th System on the Second Floor. Replaced all of the High Efficiency Air Filters. The Washable filter for the second floor system was clean and in good condition. Cleaned drain lines and condensation pumps on each system. Condensation Pumps and Vinyl Tubing on the systems in the basement were very dirty, and the tubing was clogged. Cleaned pumps, blew through vinyl tubing, and filled and tested each pump. Would recommend replacement of the Vinyl Tubing on each system to prevent any future issues. Inspected electrical components and thermostat setup on each system. Cleaned Humidifiers and replaced the Water Panels in each one. Dampers are open and the thermostats are programmed for the humidifiers to run in the Heating season. Put each system back in operation to original set points. Checked the Aprilaire Dehumidifier which was turned off. Turned on and allowed to run. System runs and then will eventually shut off in
Service call that the system was not cooling. Upon arrival found the outdoor unit was not running. Inspected components and tested capacitor. Dual Capacitor had failed. Replaced 45/5 Mfd Dual Capacitor and put system in operation. Measured refrigerant charge and found unit to be low on charge. Added 4lbs of 410-A Refrigerant to system, charging by Superheat. Checked Blower Motor Capacitor and Air Filter on system and inspected components. After adding refrigerant system was running with a 16 Degree Supply/Return Air Differential. System is operating but is overall in poor condition. The blower compartment is very dirty, the outdoor fan motor is very rusted which could lead to failure, and the system has a known refrigerant leak. Due to age and the overall condition of system would recommend replacement of the Gas Furnace/AC system.
Found wet switch tripped. Found very small amount of water in pan near side of unit. Tested drain with water, and condensation drain was draining fine. Dryer out wet switch and small amount of water a reset switch. Completed a/c inspection form and everything tested out just fine. There is small water marks down air handler where condensation has run down casing. Talked to homeowner about issue and if the switch trips and it is just a small amount of water she is going to dry it up and reset wet switch. System is working fine at time of inspection.
Service call that the Air Flow in the Home was not consistent in each room and the utility bills were higher than normal. Spoke with homeowner about issues upon arrival. Inspected system and ductwork. There are no individual Dampers for each duct work run. It was noted that no Air was coming out of the one of the registers in the Living/Family Room. Found that Flex Duct Connection under the crawl space was not connected. Spoke with homeowner about issue and reconnected the Flex Duct to the Duct Work Register in the Crawl Space. Also found 16x25x4 Air Filter very dirty and clogged. A dirty Air Filter will restrict the amount of air flow going through a system. Installed a 16x25x1 Air Filter and spoke with homeowner who is going to purchase a new High Efficiency Filter. Checked Blower Fan speed settings and settings on Nest Thermostat. Recommend a Full Tune Up/Maintenance on the system. The Gas Pressure and Combustion need to be checked and verified which is critical for the efficiency
Completed Heating Tune UPS on the Air Handler/Hydronic Coil systems. Checked Air Filters and replaced two air filters that were dirty. Cleaned and serviced all Humidifiers and set Humidity Control at the Thermostat. Inspected all Drain Lines and Pumps. Inspected all electrical Components. Put systems in operation and measured Supply/Return Air Temperatures. All systems are running to standards at this time.
