excellent technicians

I have used several different companies over the years and I think DiBiase is the best. The techs have a degree of knowledge that I have not seen before and they do not try to sell you stuff that you don't need.

Service call that the Air Conditioner was not Cooling the Home. Upon arrival, spoke with Homeowner about issue. Proceed to the Thermostat and turned System into AC Mode. Found the Blower was running but the Outdoor Unit was not turning on. Tested system and determined that the Outdoor Unit was out on Low Pressure due to being completely out of Refrigerant. Had added Refrigerant and Leak Dye to the System last year. Inspected Indoor Coil and found leak Dye throughout the Indoor Coil. Both the Indoor and Outdoor Units are from 2003. Due to age and condition, recommend replacement of the entire system. It is not recommended to replace just the Indoor Unit in this situation. Took measurements and photos of current system setup. Will follow up with an estimate for replacement. Turned the Disconnect at the Outdoor Unit Off. Left the Fan in the On position to help circulate air throughout the house.

Installed new air handler in attic and condenser outside, set on new pad with a new whip and disconnect the indoor unit was installed in a new pad on 2 sets of pump ups a new whole was drilled on the side of the house for new linesets drain and thermostat wire. An ez trap and wetswitch were installed for condensate saftey. Profiles were set to d. Triple evacuated and vacuumed down to 274 microns. 15.6 ounces added for Charge. System checked out ok. Duct work was re connected and sealed also we fixed damaged duct work with tape as well. Filter size 14x24x1 need to come back to change transition piece from white to tan... ordered at Johnstones

Checked no cooling and a leak. Peter told me that the heat pump ran and had no charge. The low pressure switch is wired system charge is 8Lb4oz. Timothy Off said they added 8Lbs of refrigerant. I not know how. They also replaced a run capacitor. Checked refrigerant charge, found 4 sub cooling. There may be a leak but we will need to do a leak search Need to schedule cooling ptu and perform leak search.

Performed ac tune up, check electrical low and high ok flushed drain test pump, replace filter, check split ok, check outdoor unit, unit is running very hard, ac unit not rejecting all the affectively, creating high pressures, which means compressor and fan motor working harder, coil is clean, check capacitor and contactor ok, unit is not performing the way it should be doing, it is cooling, but is working at extremely conditions would recommend replacing system

Installed 80% amana gas furnace and 13 seer ac. Kept existing thermostats. Installed new 16x25x1 air filter. Adapted to metal plenum. Adapted to gas line, exsisting high and low voltage. Tested system in heating and cooling and performed combustion test. Ac and gas furnace system working at manufacture specifications.

Performed cooling maintenance, found no air filter, installed 16x25x1 filter. Cleaned condensate drain. Checked voltage, amperage and electrical connections, measured capacitor values, found weak blower capacitor. Replaced blower capacitor. Started air conditioner, checked refrigerant charge, found low on charge. Topped off charge. Need a quote on replacing 3 ton air conditioner

Performed PECO Heat Pump Tune Up on System. Checked the 16x20x1 Air Filter. Air Filter was clean and in good condition. Performed PECO Checklist. While measuring Refrigerant Charge on system, found system to be low on Refrigerant. The Air Handler is over 30 years old and the Outdoor Unit is 20 Years old. Due to age, and overall poor condition of the system, the recommendation would be to replace the Heat Pump system rather than make repairs. Provided an estimate for the cost to add Refrigerant.

Performed Precision AC Tune Up on System. Checked 16x20x1 Air Filter. Cleaned Condensation Drain Line and Condensation Pump. Condensation Pump is cracked on the basin. This could leak as the pump fills with Water. Spoke with Homeowner about issue who is going to replace the pump himself. While testing the electrical Components, found the Dual Capacitor on the Outdoor Unit was testing below rating. Replaced the Dual 45/7.5 Mfd Capacitor and tested operation. Measured Refrigerant Charge on system. Refrigerant Pressure were fluctuating while the system was running. If the system was not properly installed and contaminants and/or moisture are in the system it would cause this fluctuation in Pressure. The system also appeared to be low on Refrigerant. If there is a leak in the system moisture and contaminants could be getting in. System is cooling but the Supply Temperature fluctuates about 5 Degrees +/- as the Refrigerant pressures fluctuate.
