Prompt Service!

Dibiase has given us excellent service and great advice. I initially called them after another company installed a new air conditioner that left us with so much moisture and condensation, in our basement, that we had to replace the dry wall in the ceilings. On each occasion Joe or Chris have gotten back to me immediately and been able to give me an appointment on the same day. Their advice takes into account my budget and an excellent knowledge base.

Performed Precision AC Tune Up on Trane Gas Furnace/Heat Pump system. Replaced 16x25x1 Air Filter. Cleaned AC Drain Line and EZ Trap. Cleaned Condensation Pump and filled to ensure it was pumping out properly. Inspected electrical components on system. On outdoor unit found the Dual Capacitor was testing below rating. Also found Contactor was very worn and had Arcing present. Installed a new 45/5 Mfd Dual Capacitor and a new Single Pole 24V Coil Contactor for unit. Complete all wiring and put system into operation. Measured refrigerant charge with system in cooling mode. Homeowner had noted on previous visit that the Heat Pump was not working. Turned system to Heat Mode and measured Refrigerant charge and air temperatures in Heat Pump mode. Heat Pump appears to be running with no issues. System is a Natural Gas Furnace as the Emergency Heat with a Heat Pump as the Primary Heat. Explained how system operates and due to system being natural gas, would recommend keeping unit running in Em

Performed peco inspection, checked air filter ok. Blew out condensate trap and drain. Found a 50 amp circuit on the electric heater is supplied with a 10 ga. Wire. Shut off breaker unit correct size wire is run. Blew out condensate trap. Checked voltage, amperage and electrical connections. Started heat pump, checked refrigerant charge and temperature drop across coil. Recommend adding insulation to attic, can see no insulation in areas.

Performed Quality Assurance Inspection on system. Spoke with contractor about issue with outdoor unit leveling. Unit was level, but due to the ground behind the building slopping dramatically their is a considerable amount of run-off present. Leveled the outdoor unit and dug further down into the ground. Laid more stone down and built up stone around outdoor unit pad. Also built a makeshift runoff ditch in an attempt to divert the water flow past the outdoor unit. Spoke with contractor about filling in the entire ground behind the building, and/or creating a more natural run-off. While onsite attempted to connect Honeywell Wifi Controller to indoor unit. The system was not responding to the controller. Moved controller to multiple locations to ensure it had a clear path to the unit. Called Resideo Tech Support and they said this Indoor Unit is not compatible with the Controller. Reconnected Daikin Remote control to unit and tested. Will follow up with John Borden about other options. N

Installed new mini split system in newly converted yoga studio. Mounted head on wall close to the ceiling and centered in the shed. Ran our communication wire and line set and drain to indoor head and connected it all together. Ran the other side to the out door unit and ran it partially through line hide. Set outdoor unit on stones and leveled it out. Connectrd everything to the out door unit and did a pressure test with nitro, then vacuum down to 164 MG. Tested out and went over install with customer.

Performed heating maintenance on gas furnace, upon arrival I was asked about the heat working properly, found a heat pump and gas back up, the heat pump is not heating. Serviced gas furnace, cleaned burners and flame sensor. Blew out condensate trap and drain. Checked voltage, amperage and electrical connections, measured capacitor values. Started gas furnace, performed combustion test. Checked operation and temperature rise. Please schedule cooling ptu fit lake March or early April to diagnose poor heat. Looks like oil around the coil line set connections.

Performed cooling maintenance, replaced standard air filter. Cleaned condensate trap and drain. Checked voltage, amperage and electrical connections, measured capacitor values, found weak blower capacitor. Replaced blower run capacitor. Started air conditioner, checked refrigerant charge, found unit low on charge. Customer wants to wait on repairs at this time. I explained that the coil can ice up in cooling and be expensive in heat mode.

Found outdoor unit capacitor weak. Replaced 45/7.5 mf capacitor and tested system. Also performed precision a/c tune up on carrier a/c system. Checked all electrical conections and components. Blew out condensate drain and tested condensation pump several times due to issues in the past. Checked refrigerant pressures and temperatures at indoor and outdoor units. System is working fine at time of inspection.

Performed Precision AC Tune Up on Payne Heat Pump System. Homeowner informed me that the system was having difficulty maintaining temperature inside the home. While checking system, found the Indoor Coil was heavily coated with cat hair and dirt. Brush cleaned the easily accessible pieces off of the Coil. Tested Refrigerant Charge on system. Measured Supply and Return Air Temperatures, and Measured Wet Bulb On System for Superheat measurements. Refrigerant Pressures were within range and the system was cooling at a 20 Degree Supply Versus Return Air Temperature Differential. The Indoor Coil is still dirty and this could be affecting the Refrigerant Pressures in the System. Recommend performing a dry cleaning on the coil and spraying coil with Coil Cleaning Agent to help breakup the buildup on the coil. After coil is cleaned, retest Refrigerant Pressures and reevaluate. Refrigerant May be need to be added to the system after coil is cleaned. While testing components of system, the Blo
