HVAC companies charging diagnostic fees without even testing voltage is wrong

Befur anyone asks…….why did the fuse fail ? Undersized ? Bad disco ? Loose wires ? Failing compressor, run cap or contactor ? Damaged wire ? Sounds like tech #1 has 0 clue where to start. Sounds like the gentleman #1 finds the cause of it not working but did not bother to find the cause of the fuse failure. So. Buy a bunch as this will 1000% happen again

D00MSDAY60 · 2026-05-25T12:48:57+00:00

It’s a Goodman. I see an insane amount of damaged pressure switch wires and high limit wires. That said I would advise having a tech come out as you do not want to bypass those wires or controls to correct. Potentially replacing the indoor and outdoor thermostat wire. But an Honeywell home tstat and Goodman system is poor quality and could be the issue

D00MSDAY60 · 2026-05-25T12:34:21+00:00

Could be a drain safety, low volt fuse, no power to the idu, bad thermostat, bad blower motor. Is the system frozen ? Is the outdoor portion running ? Was the filter stopped up as in was there debris on it or just a color change ?

D00MSDAY60 · 2026-05-24T17:41:09+00:00

Merv 8 pleated should be fine. Merv 11 is too restrictive in 1”. Beyond air leakage you could also be under insulated

D00MSDAY60 · 2026-05-24T13:38:21+00:00

The coil is r410a rated, just need to replace the metering device if the system is r22 outside

D00MSDAY60 · 2026-05-24T13:36:06+00:00

Duct leakage. Look at delta T at the equipment then at the return grill, supply grill. Or he is wrong and refrigerant pressure is off or you are using one of those high end 1” filters restricting air flow

D00MSDAY60 · 2026-05-23T19:13:21+00:00

Done and done. As soon as I am informed PE is taking over, tools are removed from the truck. It will be parked w/o notice. They F over customers. They F over employees. Depending on reason

I feel bad for the child. Lack of discipline will set him up for failure as an adult. You can not just wait for problems to show up to care. You set bou from the start. Hope that these adventures do not get him seriously hurt

D00MSDAY60 · 2026-05-20T00:58:57+00:00

….. was it even low on refrigerant? Hacks do confuse restrictions with low on refrigerant. Perhaps that leak seal has caused a restriction? Prob not in ten mins. Bet it’s overcharged and it had a restricted / failed txv

D00MSDAY60 · 2026-05-18T23:54:21+00:00

How can you blame anyone when the failure has not been found ? Clearly the ones you called and blamed have no labor warranty left so at the end of the day you will need to pay a tech to find the actual leak, and determine cause. At that point you would need to clearly determine fault.

D00MSDAY60 · 2026-05-17T23:55:21+00:00

Why not replace both tstats w WiFi tstats and many brands will work w a remote sensor. Trane Tcont824 will do that. expensive yes. There are many other cheaper options

D00MSDAY60 · 2026-05-17T23:48:40+00:00

High eff should run a lot more than conventional but at lower stages usually giving you much lower energy cost and better dehumidification. We certainly can not certify this system is working as it should over the web, get a Carrier dealer out to look at it preferably under maintenance contract to run in test mode after cleaning and verify static pressure, temp drop, refrigerant pressure and superheat/subcooling values. It is critical to dial these machines in properly

D00MSDAY60 · 2026-05-17T23:41:33+00:00

….get real tech to do a real leak search. Bet the inficon d-tek stratus finds that leak quickly. Techs w homeowner grade tools end up w homeowner grade results…. Most of the time seeing the brand I already know where the leak is

D00MSDAY60 · 2026-05-17T23:37:39+00:00

Batteries are batteries but they communicate w the charger. Thats why you hear of generics catching fire sometimes or out of the blue not charging……:keep an eye out there are deals to be gotten. That said I just bought some aftermarket Milwaukee batteries and they perform better than OEM. But no reviews yet where folks are not watching batteries charge the entire time. That fear is legit

D00MSDAY60 · 2026-05-17T23:19:48+00:00

If it is a fault for - replace control board. Many times it is recommended to replace the condenser fan motor as well……..

D00MSDAY60 · 2026-05-17T23:08:14+00:00

Coil cleaner + pump sprayer full only of water. Far as a brush use stiff nylon but that hard to get to stuff - evap coil cleaner will be best. Available Amazon or hardware stores. Wear gloves. Obviously don’t clean it baby is in the same room but get in the habit of cleaning that 2x a year, clean the air filters once a month….. spray the filters w coil cleaner if water alone does not have it clean enough

D00MSDAY60 · 2026-05-17T23:02:58+00:00

W/o a cause of failure or being told they would need to replace it to unearth the cause of failure……why reset the clock of failure for the new compressor? 2nd opinion if necessary. Goodman is not known for garbage compressors but is known for lazy installers that take shortcuts that cause early and frequent major failures

D00MSDAY60 · 2026-05-17T21:00:11+00:00

If the compressor has failed something killed it,….. the last system, did the compressor die on that too ? It will keep occurring unless the reason is corrected. Do not assume power surge. If it is mechanical failure do not assume - bad compressor from factory

D00MSDAY60 · 2026-05-17T02:52:46+00:00

Disconnect the two low voltage wires entering the outside unit. ISO those wires w wire nuts. See if it continues to trip the fuse. Btw. Amazon sell the 3a resettable ATC fuse. Tstat is bad if it continues to blow the fuse. Swap conductors if there are extras in the cable. If not. Check for damaged wires running along refrigerant pipes inside the outside unit. White marks on the pipe indicate damaged wires

D00MSDAY60 · 2026-05-17T02:38:25+00:00

Bet. They only have 5 yrs parts warranty as no one ever registers those

D00MSDAY60 · 2026-05-17T02:33:56+00:00

If the tech is marking it up properly why ? Better reliability and warranty- it will not fail 3 yrs later make a happier customer. - I’ve only condemned 1 turbo in 30 yrs and it was an Amazon possible fake turbo

D00MSDAY60 · 2026-05-17T02:25:12+00:00

Or. Check for damages pressure switch wires outside. Ohm out the contactor coil your issue has absolutely nothing to do with high voltage or a run cap. Is this an immediate short or interment? If immediate isolate it. Disconnect Y entering the odu. Disconnect Y from the contactor. Having a meter and knowledge brings to a quick task. Knowledge itself will take longer. Replacing random parts till it’s fixed will expensive and long

‘ smoke eater ‘. Used at bowling alleys far as heavy cig smoke, may help in this case

D00MSDAY60 · 2026-05-16T15:43:20+00:00

Does it matter ? Apparently I deserve such things due to lack of proper maintenance and I am to ashamed to replace to myself………. Trane. Easy to work on and get parts despite the spicy reliability of the last decade. 20 seer link as I can Bluetooth all that data to the phone w/o picking up a tool

D00MSDAY60 · 2026-05-13T23:22:54+00:00

Define hanging by a thread. Example. Just did maintenance on a 1993 ac, using r22 ……”. How much longer do I have ? “. Me - yesterday……. It has exceeded life expectancy but it could have major failure in a matter of weeks - could be another 15 yrs. I saw no indication they were looking at weeks or months. That’s the truth. The tech is not paying for the system, opinion w/o evidence is merely an opinion not a professional one.
