Issue was the system on the right side of house (3) indoor heads not working. When I arrived I made sure all (3) indoor units were making demand for cooling (fan speed high) Found no operation at outdoor unit, There were no active alarms at power monitor. There are 1 Over voltage and one under voltage events in history, I cleared the history so we will know in Future that should any events occur they are from a point in time after today. Under voltage setpoint 216V Over-voltage setpoint 264, There were no error codes displayed on outdoor control either. First (2) LED lit red and yellow “Normal” I reset power to unit and tested system Temperature split at all (3) heads ranging from 22-25 degrees, Good Refrigerant charge: Good (3.5° SH) System operating well at this time.

Completed AC tune up for 3 Ton Goodman AC system 19 years old Replaced 20x20x1 filter. Cleaned the 12x12 basement filter in floor grille. Homeowner will order 12x12x1. There is a pop in the return drop when blower ramps up and shuts down. This is fairly common, not a concern. Blower wheel has considerable amount of dirt build up. Provided estimate to remove blower wheel and clean wheel and housing. Will improve/increase air flow if cleaned. Indoor has some rust as to be expected given age of system; outdoor coil in good condition Inspected wiring, controls, electric motors and components; left estimates for surge protectors Measured temperature split (18.5) and static pressure Inspected drains; cleared EZ trap, tested pump; added treatment tabs to drain pan. Recommend installing a water safety that will Shut equipment down if water is detected on floors near indoor equipment. Provided estimate for wet switch, Checked integrity of compressor motor (mega ohm test) Assessed ref

Upon arrival, found outdoor unit with red eight flash error code meaning faulty outdoor PC board, power issue. Reset system from the outdoor disconnect and ran all heads for 30 minutes supply temperature was 42 and system was running to standards. checked refrigeration charge all to manufacture specifications.

Homeowner mentioned that they had to manually empty the condensate pump to get system to work. When I arrived I brushed out EZ trap body. Then tested pump. Drain line Appeared to be clear. I removed the short piece of discharge tubing and blew drain line with C02 just to. E sure drain is clear. Tested several times. Drain terminates in 1/2” pvc at the work sink at the other side of basement. Replaced 18x20x1 air filter, Was last replaced 6/22/23. Very dirty. Recommend replacing every 3-4 months. Tested system afterwards. 22° Temperatures split (77-55) Good Recommend adding condensate pan treatment tabs every month. System operating well at this time.

Completed Quality Assurance Inspection for Laars Combi Boiler. (3) Space heating thermostats: 2 are radiant floors, 1 is radiators. Homeowner mentioned that her husband said water pressure at 3rd floor shower was lower. Ultimately I found that the house water pressure is high 95 psi so with their old domestic hot water heater the pressure would have been too high. In other words he is used to pressure that is too high. The inlet screen of domestic hot water for new system is clean. Water pressure ok. Set warm weather shit down temperature to 70°F meaning boiler will not operate when it is 70°F or warmer for the sake of conserving energy, (It will run to keep domestic water storage tank at a minimum temperature) Also made sure the max domestic water temperature is set to 140°F because of mixing valve. Inspected all aspects of install: mechanical, piping, control setting, wiring. ETC. Tested operations of boiler. Combustion test: Pass Install passes quality assurance inspection

Reviewed equipment and Mike told me the units in back bedroom left and dining room were leaking water indoors. Tony apparently repaired drain with new connector. Removed lineset cover and found tubing smashed. Pulled slack and opened up tubing. Tested all other drain lines and found ones on the right side not draining due to length of horizontal run. Removed linehide and ran 2 of the drains straight down and retested.

Created estimate

Removed oil boiler & 50gal water heater installed Laars combi boiler, reused zone board but reran wiring to new pumps pumps new switch outlet on boiler, water filter for boiler loop, repiped unit, drilled and ran intake and exhaust, teed off and ran gas over to boiler, set DW to 120 leaving mixing valve, all rads bled, both zones tested Paid full by check

Fully assessed no heating or cooling situation on recently installed gas furnace a/c. Found furnace condensation line leaking. Re glued fitting. Also found exahaust 2” 90 leaking. Re glued . Also performed quality assurance on system. Checked r-32 refrigerant pressures. A/c is working properly at time of service.

4/10/26. Performed precision a/c tune up on 2018 American standard a/c. Replaced 16x25x1 air filter. Checked all electrical connections and components. Found reme air scrubber cell was at replacement interval, replaced cell. Cleaned out ez trap. Checked temperature split. Checked refrigerant pressures and temperatures. A/c is working properly at time of service.
