5/20/26. Homeowner gave system a call for cooling. Found 2017 Daikin a/c not starting up but humming. Found failed 45/5 capacitor. Replaced capacitor and tested operation. Also performed precision a/c tune up. 20x25x1 air filter was just replaced. Checked all electrical connections and components. Tested condensation pump. Checked temperature split. Checked refrigerant pressures and temperatures. Found no water protection on the system to prevent water leaking on finished floor, recommend installing a wet switch. Also found uv air purifier was not working. Provided estimate to install a new uv air purifier correctly above evaporator coil. A/c is working properly at time of service.

Completed AC tune up for 3.5 Ton Daikin AC system Equipment is gas furnace+AC installed 3/14/16 by another contractor. 10 years old 20x24x1 filter ok left one on site Indoor and outdoor coils in good condition Inspected wiring, controls, electric motors and components; left estimates for surge protectors Measured temperature split and static pressure Inspected drains; tested pump; pump is clean. Homeowner has been adding treatment tabs monthly. System does lack overfill protection so I provided estimate for EZ trap. System also does not have a floor water detection switch. So provided estimate for wet switch. Will shut equipment down if water ever makes it way onto floor Checked integrity of compressor motor (mega ohm test) Assessed refrigerant charge checked pressures. Good AC system operating well at this time. Equipment is 10 years old which is considered replacement age for this type of HVAC equipment. (Forced air)

5/17/26 Dan I arrived to the customers home for a odor when she runs the AC. I inspected the indoor coil found no oil residue or refrigerant leaks. I checked my outdoor pressures found good I had great sub cool and superheat. I inspected the return duct the filter and the base of the cabinet. I did recommend to the customer to do a nontoxic chemical clean on the indoor coil. I left a price in estimates for cleaning the indoor coil and I left a price for UV lamp installation to mount over top of the indoor coil. She will reach out to the office on Monday after she talks to her boyfriend. I collected for my diagnostics for today total due is $158.61 paid by credit card. I left an estimate for an indoor coil cleaning non toxic and smell type chemical, cost 436.18 I left a estimate for a uv light installation cost $706.35 She will review with her boyfriend and get back to us .

Completed (2) AC tune ups: -1st floor system 4Ton Daikin Inverter/natural gas furnace hybrid. Daikin Fit thermostat. Dates to 2019 7 years old -2nd Floor system 2 Ton R22 Lennox AC/Gas Furnace dates to 2003; 23 years old Basement system filter is 20x25x1 electrostatic. Clean 2nd Floor filter 14x25x1 also clean. Left one for homeowners on site For each system: Inspected Indoor and outdoor coils: Indoor coil 1st floor good, cleaned outdoor coil with available hose (very little debris to speak of), indoor coil for 2nd floor rusted as to be expected given age. Outdoor coil clean. Inspected wiring, controls, electric motors and components; left estimates for surge protectors for 2nd Floor system. 1st floor equipment has surge protectors Measured temperature split and static pressure both systems ok (20.5 for 1st floor system) (19.5 for 1st floor system) Inspected drains; cleared trap in basement. Both drains are piped to a floor drain. Provided updates estimate to install pum, EZ trap

Completed AC tune up for 3.5 ton AC system. Equipment is 3.5 ton AC with gas furnace installed 8/2018 7 Years old. Found very dirty Aprilaire 413 filter. Return static pressure as a result was very high. Replaced filter with one from truck. Homeowner uses a mist humidifier in the winter. If a mist humidifier is used with anything other than distilled water a fine dust will be vaporized and that dust will cling to the filter media causing the filter to become dirty very quickly. This particular dust on a filter may appear clean at a quick glance because the dust is white in color (this also happens when drywall work is done and dust from sanding coats the filter) Homeowner asked that I leave the dirty filter so she can show her daughter. Using distilled water for the mist humidifier will solve this issue. *This won’t be a problem when humidifier is not being used. Indoor and outdoor coils in good condition Inspected wiring, controls, electric motors and components; left estimate

Completed AC tune up for 3 .5 Ton Amana AC system 16x25x1 filter ok Indoor and outdoor coils in good condition Inspected wiring, controls, electric motors and components; left estimates for surge protector for indoor equipment circuit. Outdoor equipment has surge protection. Measured temperature split and static pressure Inspected drains; cleared EZ trap, also wrapped EZ trap body with insulation tape to prevent from sweating and dripping on return drop. added treatment tabs to drain Checked integrity of compressor motor (mega ohm test) Assessed refrigerant charge checked pressures. 5° Subcooling. Good AC system operating well at this time. Homeowner renewed plan membership today.

Completed AC tune up for 4 Ton Trane AC system Equipment is gas furnace AC with 3 zones installed 1/21/26 The “change humidifier pad” reminder is part of the humidistat. It is based on a timer that is needed with certain humidifier applications. It is not necessary in this application so I disabled the “change pad” reminder. The hydrocore of this humidifier will need to be replaced next heating season. Replaced 16x25x1 filter, there is a new 12x12x1 filter in basement return grille. They will replace this one soon. Indoor and outdoor coils in good condition Inspected wiring, controls, electric motors and components; Measured temperature split and static pressure Inspected drains; cleared EZ trap, tested pump and added treatment tabs to drain Checked integrity of compressor motor (mega ohm test) Assessed refrigerant charge checked pressures. Charged system 1#4oz r454B refrigerant to meet manufacturer subcooling 12° and to match pressure curve in manufacturer literature. System
