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 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

Performed Six Month Inspection On Amana Inverter System. Replaced the 20x22x1 Air Filter. Spoke with Homeowner about checking Air Filter every 30 Days and changing as needed. Also recommend not exceeding a Merv-8 rating when changing the filter. Recommended leaving the Blower Fan in the Circulate option to help balance the First and Second Floor Temperatures as well as utilizing the Air Scrubber. Cleaned EZ Trap and Condensation Pump. Put system in Test Mode and measured refrigerant Charge. Found Subcooling Levels to be slightly low and Superheat Levels were higher. Added 1 lb of 410-A Refrigerant to the system to balance these levels. System is operating to standards at this time.

Service call that the AC was not operating. Upon arrival, spoke with Homeowner about issue. Previously had issues with the Condensation Pump being clogged and shutting the system down. Inspected Pump and found that it was working properly. After troubleshooting system, determined that the Thermostat had failed. Installed a new T6 Wifi Thermostat. Programmed thermostat and setup the Wifi with the Homeowner. Tested operation of Heating and Cooling Modes to ensure proper operation. Reviewed Thermostat operation with Homeowner. Filled and tested operation of Condensation Pump to ensure that it was pumping out properly.

Service call that the AC was not working. Upon arrival found Thermostat was blank and the system was not running. The Condensation Pump had filled and failed to pump out, shutting the system down in Safety Interlock. Removed the Condensation Pump to inspect. Blew through the Vinyl Tubing to ensure it was clear. Found debris stuck in the Discharge Check Valve of the Pump. Removed the Check Valve Fitting to Clean. Removed debris and reassembled Pump. Put system back in operation. Filled Condensation Pump 15 times to ensure that it was pumping out properly. There is no visible damage to the pump that was found. The debris that was clogging the Check Valve may come from the Pump Motor. Spoke with Homeowner about issue and replacing the Pump. If something internal has broken apart and the pump clogs again, recommendation would be to replace the Condensation Pump. Included an estimate for the replacement of the Pump.

Found dpdt relay very hot like it was sticking at times, also found breaker breaker for one part of strip heater now is broken and won't reset at all. This also powers the blower circuit. Told home owner the only thing I can't do now to just get it to work temporarily is to install the new relay and wire the fan moter directly to the other breaker . This is not a good fix , but a temporary solution for now.

Service call that the Heat Pump was not working. Upon arrival, found Thermostat set to 80 Degrees and the Indoor Temperature was 60 Degrees. Proceeded to the Air Handler to troubleshoot. Found Blower Motor was not operating. Turned Breaker off at the Air Handler to inspect Blower Motor Wiring. When we turned the Breaker back on the Blower began operating. The Relay in the Air Handler may have been stuck open causing the Blower not to run. Also found Air Filter excessively dirty and blocking Air Flow. Installed a 20x20x1 Air Filter. Tested Supply Temperature at 95 Degrees with a 65 Degree Return. Checked Refrigerant Pressures to ensure they were within range. The Air Handler is from 1982 and the Outdoor Unit is from 2001. The system is operating very inefficiently due to the very old age. System needs to be replaced due to poor condition. The office will be in contact to schedule an estimate for system replacement.

Was informed that Water was in front of the Furnace on the Concrete Floor but not in the Auxilary Pan that is below the Dehumidifier. Tested operation of Dehumidifier. Checked Condensation Pump and poured Water into Pump multiple times to test Operation. Tested operation of Humidifier and poured Water Through the Drain Pipe to ensure it was draining properly. Checked Dehumidifier for proper pitch. Unit is pitch slightly towards the Drain. Inspected Duct Work to ensure there was no water from Humidifier leaking into the Duct Work. Inspected Piping around Furnace and above Furnace and found no signs of leaking. Furnace is an 80% Furnace and the Drain !ine for the Humdifier is clear. Discharge Tubing on the Condensation Pump is draining properly into the Wash Sink. If the Dehumidifier was leaking then the Auxilary Pan underneath of it should be homding water. Please mon
