If you're in the West Chester, Chester County PA area and need HVAC work done - I can't recommend DiBiase highly enough! They were, and are, expertly skilled at what they do, extraordinary communicators before/during/after the install, and a pleasure to work with. The team were all complete professionals. I have high expectations but they exceeded all of them!

Installed new daikin mini split in basement and attic bedroom. Installed new lineset and linehide for each unit. Installed new outdoor unit on bracket. Installed new 20 amp breaker and wire for unit. Installed new drain line and communication wire for units. Made all refrigerant connections and pressure tested to 475 psi and evacuated below 500 microns. Made all necessary high and low voltage connections for each unit. Tested system in heating and cooling, system working properly.
Arrived to do ac maintenance, Checked thermostat for operation, checked filter, primed and cleaned EZ trap, checked blower motor amp draw, tightened all electrical connections, checked temperature split. Went outside and checked compressor amp draw, condenser fan motor amp draw, checked dual capacitor and refrigerant pressures. System is working correctly at this time.
System was operating well when I arrived. Cycled system on and off and AC performed as designed. Checked controls, wiring and electric motors. Checked temperature split and checked refrigerant data. AC is operating well at design conditions the time of this service Recommend upgrading thermostat. Provided email estimate.
Performed cooling maintenance, checked media air filter ok. Shut off humidifier for summer. Cleaned condensate trap and blew out discharge line. Checked voltage, amperage and electrical connections, measured capacitor values. Started heat pump, checked refrigerant charge. Checked operation and temperature drop across coil.
Checked no cooling complaint, found air conditioner running. Checked air filters, checked refrigerant charge. Found unit under charged. Topped off charge, balanced by sub cooling. Checked operation and temperature drop across coil.
Found thermostat calling for cooling up to defrost board but low pressure switch is open. Found no refrigerant in the system. Found some oil it look like at both outdoor and indoor coil. Recommended to Wayne to replace the system. Called our office and discussed all the details. Office to send over replacement estimate.
First day Disconnected and removed old oil furnace, also removed customers old humidifier per customer. Removed old outdoor unit line set line voltage and low voltage wires. Installed new electric heat pump heater and AC, installed new Bosch outdoor unit on pump of legs, also installed new disconnect box pad and stone. Ran new three-quarter inch refrigerant lines along with 8 wire thermostat wire. Breached the refrigerant lines indoor and outdoor and play system on a nitrogen test system held for 30 minutes at 300 psi. Then placed system on vacuum pump pumped down 157 µm, Lines that was under 15 feet. Installed new easy trap ran new vinyl tubing to discharge inside at the plumbing stack. Also capped off old chimney and sealed up line set holes inside and out customer is getting Mark Hetchler to remove oil tank and oil inside. Installed new Bosch air handler on new return box. Supported air handler with 3 inch PVC in the box. Installed new supply ductwork. Taped and sealed all holes
Performed cooling maintenance on attic second floor heat pump. Cleaned condensate trap and drain. Replaced air filter. Checked voltage, amperage and electrical connections. Measured capacitor values ok. Started heat pump, checked refrigerant charge, found system low on charge. Topped off refrigerant charge, balanced charge by sub cooling. Checked operation and temperature drop across coil. Need to schedule first floor cooling maintenance. Need to quote to level first floor outdoor unit
Performed cooling maintenance, checked air filter ok. Cleaned condensate trap and drain. Checked voltage, amperage and electrical connections, measured capacitor values. Started heat pump, checked refrigerant charge. Checked operation and temperature drop across coil.
Plan member AC maintenance 2.5 Ton Amana AC: Replaced 20x20x1 Filter. Measured static pressure and temperature split. Checked wiring, controls electric motors and components. Checked condition of both indoor and outdoor coils. Checked EZ trap and drain. Tested pump. Checked refrigerant pressures and diagnostics. AC system is operating well at the time of this maintenance.
Plan member AC maintenance; 2 Ton Carrier Infinity AC system: Replaced 14x25x1 Checked and tested drain. Measured temperature rise. Measured static pressure. Checked wiring, controls, electric motors and components. Both indoor and outdoor coil are in good condition. Checked refrigerant pressures and diagnostics. AC system is operating well at the time of this maintenance.
Had homeowner give thermostat a call for cooling. System came on and had no codes at the outdoor board. Checked refrigerant pressures, pressures were good. Got homeowner to turn temperature up to cycle of outdoor unit. Turned temp back down in cooling, system came on correctly. Homeowner had turned down temperature on way home from vacation and said it was at 75 when he came home and expected it to be cooler. System is working fine at time of service.
Found after hooking up gauges to thru the wall heat pump system, found head pressure climbing the whole way to 500 psi and shutting off. Found outdoor fan motor running but cutting out in the middle of a call. Fan motor and compressor were replaced by another company. Went to a different unit inside the building and checked how ecm fan moter was wired. ( could not find a schematic for this exact motor online). Changed wiring to match other apartment fan motor wiring now fan motor is staying on and system is cooling with a 15 degree split. Heat pump system is working at time of service.
Water leak from kitchen mini split head, noticed some water dripping from front cover, removed cover and inspect drain line, found drain line not connected and draining directly behind wall, tried to re connect drain line, would not stayed together, needed longer piece, added 3 extra inches of drain line and strap drain line along line set and creating slope alway from unit, after repairs check drain by adding one gallon of water into drain pan, drain line is draining ok with no issues. Ran unit for 2 minutes (customer had to leave) filters need to get clean, customer will take care of them since he needed to leave. No charge installation warranty
Performed ac tune up on two Lennox units, 3 and 2 ton check electrical low and high voltage connections, replaced filter flushed drain check airflow return and supply ok inspect both indoor and outdoor coils, check outdoor unit refrigerant r22 pressures capacitor and contactor, both units contactors are in bad shape making sound, capacitors are still within manufacture standards, both units uses R22 Freon, no longer available, first floor compressor takes a minute to come on, it’s a sign that will be going bad soon, outdoor disconnect is very difficult to removed pullout disconnect, provided an estimate to replace both contactors and adding hard start assist to both unit, and replacement of high voltage disconnect would recommend replacement of both ac units. Home comfort consultant to reach out to customer regarding new ac systems proposal.
