Fully assessed no cooling situation on 2023 amana a/c system. Found indoor control board saying ac2 but outside unit not operating. Found outside unit locked out on 01 err code which was ( low pressure cut out trip) reset system. Found a small rub on low pressure switch wire but not rubbed the entire way thru. Put electric tape over wiring and resecured with zip tie. Found 199 psi standing pressure but still locking out on low pressure lock out code. Ohmed out low pressure switch and got an OL code. Found pressure switch was stuck open without system even trying to run. Jumped out pressure switch and everything ran normally. Pressures were 300/122 with 3 subcooling. Low pressure switch has failed. System was installed by dibiase 1/6/23. Put in a temporary jumper for now to jump out low pressure switch safety. This is only temporary and need to install an external pressure switch to protect the compressor. Need to order parts customer paid in full. Customer currently has a/c.

Fully assessed no cooling situation on 2021 amana heat pump system. Found blower running inside at furnace, but nothing running outside. Found heat pump locked out on an L1 error code which means “low pressure lock out”. Found standing pressure of 254 psi in the system. Made sure low pressure switch was closed with the unit off which it was. Reset power and tested operation. Ran system for about 20 minutes and checked pressures they were 286/115 with 8.2 subcooling very good. Checked temperature split it was 29 degrees. 16x25x1 air filter was some what dirty, homeowner to replace. Recommended installing an ecm surge protector for blower motor. Possibly just a fluke issue with the low pressure lock out. Told homeowner to keep an eye on it. A/c is working properly at time of service.

Homeowner described that temperature rises to around 71° in the afternoon. Thermostat on first floor wall near hallway. This morning when I arrived the thermostat was satisfied 68° Homeowner put sticky notes around the evaporator door and bypass pipe of humidifier noting air leaks. I taped and siliconed sections as appropriate. It is very common for these sections to leak some air especially during high fan speed operations. The trunk duct is inaccessible above drywall soffit and ceiling. I can feel air coming from there. Refrigerant pressures are Good 10° Subcooling. Would be a good idea to come back and place an insulated koozie around TXV. Please have tech bring one with upcoming AC tune up. System operating well at this time.

Fully assessed water leaking situation on recently installed Hisense mini split system installed by dibiase. Found water dripping from mini split head. Found condensation drain going up hill over top of linset as it exists the wall. Was able to break out some of the dry wall and pull on condensation hose from down below to get it tucked under linset. Used water bottle and poured water over the coil, no water dripped from mini split head. Put system into cooling mode and tested operation, did not see any more water dripping. Let customer know to keep an eye on it and and further issues we would need to guys and extension ladder to re route the drain even more. A/c is working properly at time of service.

Fully assessed no cooling situation on 1997 trane a/c with 80% gas furnace. Checked all electrical connections and components. Found air filters very dirty on both systems, stuck in return drop. Removed, homeowner to replace (2) 18x24x1 filters. Looked over indoor evaporator coil very rusted and corroded also looked like refrigerant oil leaking inside. Also found gas furnace is in rough shape a lot of rust all round inducer assembly. Went outside to outside unit and hooked up gauges. R-22 pressure were very high head pressure 245/77. Also found burnt contacter and wiring inside outside unit, entire system needs replaced at this point repairing isn’t an option. Talked to the wife she is going to talk to her husband first then give us a call to set up a time to come out to give a replacement quote.

No cooling for 1st floor system 2 Ton R22 AC with 60,000 BTU Gas furnace located in basement hanging on unistrut. Found very dirty 12x24x1 filter. Replaced with 1 that homeowner had. Informed hi. That this was the last of this filter he had down there. Needs to order more. Found compressor not running. Cause is failed 30/5 uF dual capacitor. Offered to replace today. Replaced capacitor and wiring connectors. Tested system operations. Found unit very low on R22 refrigerant. Will it perform well while running this low on R22 refrigerant and may ice up inside. Most sensible thing to do is to replace the HVAC system. Consultations from Dibiase are free. I did provide estimate to charge system up to 3# R22 refrigerant but this is not recommended because we cannot guarantee how long charge will last. We set up a system replacement consultation for today, He will make a decision once he has concrete pricing.

Completed AC tune up for 3 Ton Trane inverter system Installed 5/14/24 by Dibiase 2 years old.

AC System operating well at this time. Homeowner renewed (2) plan memberships -AC plan membership -Oil Boiler plan membership

5/18/26 Dan I arrived to the customers home to service their 1 yr old bosch a/c system . I checked the wiring connections and the voltages . I checked and found the indoor air filter is good , the filter size is a AA313. ( customer replaced about month ago ). I Inspected the indoor coil and tested the primary drain pan and cleared and tested the water drains and traps if applicable. I Took indoor temp splits at the return and the supply and checked the blower motor condition and operation. I looked at the outdoor unit wiring connections and voltages . I inspected the outdoor components and checked my unit pressures by using super heat sub cool method. System in good operating condition at this time.

I arrived to the customers home for a blank thermostat . I Found nothing wrong with the equipment itself . Found blank thermostat due to the condensation pump over flow switch was tripped. I had no power to the receptacle that the pump was tied into and didn’t have power to other working receptacles in the basement. The son helped by checking the gfi’s through out the house and found 1 in the upstairs bathroom was tripped. When he reset the gfi all the receptacle began working in the basement and the condensate pump came back on . The system is back up and running. Did charge for diagnostic fees not a warranty call not an issue with the equipment. I collected for $174.47 paid by cc.

5/15/26 Dan I arrived to the customers house to look at a blower wheel on a mini split to be cleaned , he wanted a quote for the cleaning . I went around and recorded all equipment in the home. Customer has three separate systems in the house first system is a Mitsubishi mini split with three heads and one outdoor heat pump. The other system is a Mitsubishi Mini split, one indoor one heat pump, and the other system is the main house furnace and AC. I did quote the customer for chemical cleaning his three heads on the one mini split system, he declined at this time of cleaning wheel, but he did want to add a service contract through us . Total contact price is $655 for the year for all the customers equipment. He just had the ACs done from his previous company. He would like to start his new contract with us in the fall, I did leave the chemical cleaning estimate in estimates for him to review for a later time . The total collected today is $804.40 paid by credit card.
