No cooling: Homeowner described indoor equipment running but air not cool from vents. When I arrived started at outdoor unit. Found outdoor fan running but compressor not running. 30/7.5uF capacitor failed (reading 0) on compressor side. Offered to replace capacitor and test system. Homeowner agreed. Replaced capacitor and wiring connectors as necessary. Allowed system to run. Checked refrigerant data 12° SC temperature split 73-52=21° Good (outdoor dry bulb temperature 70°F) System operating well at this time. Equipment dates to 2015. Parts warranties other than funace heat exchanger no longer apply. 10 years is considered average lifespan of a forced air HVAC system.

5/26/26. Fully assessed no cooling situation on 2021 trane heat pump system. Found no power to the thermostat. Found 5 amp fuse blown. ( this is the same issue that happened last summer). Recommend to homeowner that we install a separate transformer for air scrubber. Homeowner agreed. Installed 40va transformer and tested operation. Checked 410a refrigerant pressures they were 254/122 with 3 subcooling. A little low on subcooling but still have a 19 degree split at indoor unit. Heat pump is working properly at time of service.

5/26/26. Fully assessed water leaking situation. Found the way the condensation drain was ran it was not draining correctly. Talked to David about how to run drain to also accommodate him finishing the ceiling above the washer and dryer. Re ran condensation line and tested operation. A/c is draining properly at time of service.

No cooling Equipment is 3.5 Ton AC with 100,000 BTU furnace. Furnace dates to 2019 7 years old; coil is uncased.* Basement is a crawl basement with low ceiling. AC dates to 2007, 19 years old Found water in equipment pan> tripped wet switch. Removed and Dried with wet vac. Brushed put trap and available cleanout. Tested pump by adding 1 gallon water to trap cleanout. Tested systems with probes on refrigerant service ports. I noticed the compressor kick off and lights flicker on one occasion but then stop and compressor ran another 7 min or so. Ultimately found wet switch contacts wired to the Y and C of the outdoor unit low voltage. As if the technician who wired it thought the safety wires were the outdoor low voltage wires. Fixed wiring. Wet switch and condensate pump safety now wired in series so that either or both with break power to thermostat. Outdoor low voltage wires now wired to Y and C on board. Afterwards allowed system to run in cooling. At first No water leaks and p

Mini split wasn’t producing cooling or heating found low with barely any charge. I began leak searching the line set. The outside lines at the heat pump mini look fine. Inside line on the suction side was leaking found the 3/8 nut wasn’t tight was loose and you could hear the refrigerant leaking behind the wall. I repaired the leak and tightened up the fitting and soap bubbled again at all fittings found good. I added fresh charge back in the system , added 2 lbs. back in . The system is back up and running at this time. Please follow up with the customer in about a month. No charge recall from installation.

11 year old gas furnace with 2.5 ton AC. Piston metering System running at 60 psi. Very low on refrigerant. Conducted an electronic leak search at indoor and outdoor coils as well as at braised joints. Could not pinpoint any leak. Offered to charge system and add a leak detection dye to help us find leak(s) in the future. Cautioned him that the only true guarantee would be to replace the system. He decided he wants to charge the system for now and plan on replacing it next year. Also found weak 5uF blower capacitor and the FAN side of the dual outdoor capacitor also weak. Offered and left estimates to replace each. Also provided estimates for surge protection and for water/drain safeties Customer provided a mailer coupon for waiving diagnostic fee. See photo. We decided on plan membership and to charge the system up to 3# R410A refrigerant. Used the superheat method to charge system to design superheat (based on outdoor temperature and indoor return wet bulb) Final refrigerant

Luis 5-21-26 Performed ac tune up on trane system. Outdoor unit is from 2011 indoor coil from 2020 Check filter and replace customer supplied filter, flush drain ok check supply and return air ok 20 temperature difference. Checked outdoor unit refrigerant pressures capacitor and contactor. Cycle heat pump ok. System currently operational but nearing end of normal life expectancy. Due to age, replacement of system should be considered in near future.

I arrived to look at a new mini split that was put in at the end of August. It is leaking a lot of water. I did confirm that drain line is clear. The issue that I’m seeing is the drain line comes across the back of the mini split with the line set goes up and out through the hole doesn’t have great pitch, two things one we can remove the covering in the mini split and see if we can adjust the drain line or we can use a pump for this unit the drain the water. I would probably recommend you guys or send the install crew back I will talk with management about this unit .

Luis 5-20-26 perform quality assurance on recently installed system first heat and ac unit. Check all settings on indoor and outdoor ok. All electrical ok. Check refrigerant levels ok test water safeties ok. No corrections were needed. System pass QA. turned off humidifier for summer.

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.
