Kennett Square, PA

Found “Y” call (low voltage command ror cooling randomly opening). Mitigation board “Normal” slow flash. Found drain pitched every so slightly backwards preventing water from draining quickly. Float was moving very close to open position. Redid drain line to have better pitch with clamp. Also dried out mitigation sensor and its wiring harness. And place in a spot where it will less likely get hit with any water. And wrapped wiring harness connections with electrical tape. Checked through all low voltage wiring connections. Checked power monitor. Good. After making these changes AC ran as designed for 15 minutes without any interruptions. There were thunderstorms and I had no service at end of this call.

Completed QA 1:1 Minisplit install Hisense 18,000 BTU indoor head. Inspected wiring, controls: Power monitor settings: Over-voltage 264; Under-voltage 216; open in 1.5 seconds, restore in 2 minutes. Cleared event log. Measured temperature split: 21° Checked for refrigerant leaks at the (2) accessible joints on outdoor unit Breaker is 20A Install passes QA

Completed QA for install: Bosch hyper heat 4 Ton Heat pump/air handler system. Inspected all aspects of install: mechanical, wiring, control settings, ductwork connection, etc Filter Aprilaire 413. Added clamp to 3/4” pvc drain to improve pitch slightly. Wrapped EZ trap in foam insulation tape. Wired safeties in series to produce a custom alert that notifieshomeowner and shuts off cooling and energizes fan.Verified fan speed dipswitches Measured temp split 20° GoodPressures 292/116 at 55 Hz Set power monitor 264 Hi; 216 Low, delay .5 seconds da, reset in 120 seconds.

Replace failed blower motor Luis 7-29-26 After replacement of oem blower test system operation cycle ac unit ok, system is back in working order.

Completed AC tune up for 3 Ton Trane heat pump system. Equipment dates to 2014, 12 years old. Replaced Aprilair 501 filter 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; cleared trap and cleanout. tested pump; Recommend wet switch: safety switch that will shut equipment down if water is detected on floors around indoor equipment. Checked integrity of compressor motor (mega ohm test) REME air cleaner cell is due for replacement. Provided estimate to replace REME cell. Assessed refrigerant charge checked pressures. 7° SC Good AC system operating well at this time, however system is beyond expected lifespan of forced air HVAC system. Repairs to major components are more likely to occur and are more expensive at this age. In-home consultations where quotes for new systems are provided are free fro Dibiase.

7/27/26. Fully assessed blower motor on 24 year old carrier oil furnace. Gave system a call for cooling. Found blower motor tight and humming loudly. Found 15 mfd capacitor tested good, failed blower motor. Called one distributor and found it, it’s about 2-3 days out. Homeowner wants our warehouse to call around to see if anything can be found faster. Sent over price estimate.

Luis 7-27-26 Customer called in for no cooling Amana 3 ton system from 2016 not cooling. Found no power to outside unit, reset breaker and breaker tripped. Check wiring and electrical components, found start capacitor broken in pieces, check wiring to compressor, compressor harness melted. Check windings resistance found start winding shorted to ground. I also check indoor coil for any leak. Found small signs of dye inside evaporator coil. I provided estimate for repairs. Unit has 10 year parts warranty, customer responsible for material and refrigerant. • No obligation quote to replace system • A Comfort Specialist will provide several options to suit your comfort needs and budget • New equipment can offer better reliability, greater efficiency and improved comfort • Higher efficiency models run quieter and cost less to operate • Gain peace of mind with manufacturer and service provider warranties

Estimate

Luis 6-24-26 Performed ac tune up on 2.5 ton carrier unit from 2003. Check operation from indoor and outdoor units. Replacement of customer supplied filter. Check drain inspect air delivery system and electrical connections and components. Check airflow supply and return. Check outdoor units electrical system and refrigerant cycle. System is very old. Most of the components are reading below standards indicating unit will most likely breakdown soon, indoor coils is fully corroded potential for leaks. Blower motor cap reading below standard, outdoor electrical system is reading below minimum levels. Fan motor makes noise from windings every time it starts and stops. Capacitor and contactor readings below normal. Some of the outdoor coil fins are damaged restricting airflow, crating high pressure and making compressor run at hotter temperatures. I provided estimate to replace all those parts (except refrigerant parts no longer available). These repairs would restore immediate functional

Luis 7-23-26 Customer called in for no cooling. Carrier outdoor ac unit from 2006. Indoor coil was replaced in 2016. Indoor unit runs, oil heater high boy. Test system operation outdoor unit two stage Copeland compressor. Unit would start but no pumping, after seconds compressor goes into high thermostat overload. Check compressor valves operation, compressor valves are damage and can’t pump refrigerant. New compressor is needed. This type of compressor is very hard to find now days. Total cost for compressor is over 7 thousand dollars. My final recommendation is to get an estimate to replace system. Home comfort consultant to come out tomorrow morning at 9 am.
