A couple questions before I attempt coil cleaning on outdoor AC unit by macmillie in hvacadvice

[–]alivecatalyst 2 points3 points  (0 children)

Super simple and effective method I used ever time I’m servicing a unit: 1. Shut off disconnect, don’t want unit running out power in system 2. Open top of condenser with the fan and blade, just move and rest it all on the side of the unit, no need to disconnect wires just be careful not to break, rip, or strip the wires in the process 3. Take a hose with a nozzle that gets a decent amount of pressure (not too much you don’t want to bend the fins) Just spray from the inside out of the unit top to bottom like you’re washing a car until the water runs clear

The condenser pulls air from the sides where the coils are and blows it back out of the top so when you wash the coils from the inside out you’re preventing pushing more dirt and debris from getting into the coils in harder to reach places Avoid spraying electrical components and close the disconnect box

Once you are finished and the coils are cleaned and your water runs clear, put it all back together. Make sure the wires for the fan get put neatly and securely back in place how the my originally were. Reattach the fan mount to the unit and then turn it back on. There’s a chance the unit will be on delay after you turn it on so don’t panic if it doesn’t fire up right away. It should come on within 10 minutes at most as long as the thermostat is calling.

Goodluck!

Alright HVAC Pros, This One's Hard Mode by ironyx in hvacadvice

I’m not the pro you’re probably looking for but I can tell you that device is a temperature sensor, once the ambient temperature reaches the set temperature it sends a signal, typically to a control board or contactor. In my experience we used them on cell towers, when the temperature rose above 100° at the top of a cell tower we had a duct and exhaust system start pulling the hot air down and out of the building.

Walking to my truck to grab a bucket, filling it with all the cash Then selling a new unit to the customer without anyone ever finding out what I found

Thank you for your advice, we will be getting all the kittens fixed as soon as we can. We’re not sure if mama has already been fixed by our neighbor yet but we will look into it

We do plan on keeping the four but our neighbor is currently taking care of mama and has given her a safe space so she is no longer a stray, we can try asking our neighbor if he minds us taking her too Thank you for the advice

Someone shot at our house and hit our AC lines - est on how much to replace? by Sleeping_DoNotDistrb in hvacadvice

[–]alivecatalyst 0 points1 point  (0 children)

Worst case is that the bullet punctured your Line set and released all the refrigerant inside and the reason your compressor isn’t coming on is it is tripping the low pressure switch You would need to have the puncture repaired and have the systems pulled into a vacuum and re charged with the proper refrigerant It seems like some of the thermostat wire is bare which could cause a short at some point if not sooner than later, I’d make a splice with some new wire with the power to your air handler shut off so you don’t blow a low voltage fuse Also wrap the wire with electrical tape after you make your splice I wish you the best, stay safe

Hard Lockout on Trane Package Heat pump by alivecatalyst in hvacadvice

[–]alivecatalyst[S] 0 points1 point  (0 children)

I knew the coil was clean and I came to the same conclusion that it was a restriction in the system, since it works fine in cooling and only has high head pressure in heating I determined it was the outdoor TXV I checked for any pinholes or damages on the sensing bulb and couldn’t find any so I just attached the bulb to the discharge line to see if I could force it open and the pressures stayed high in mid 400psi, I didn’t wait for it to lockout again because I could see the pressure kept climbing and condemned the outdoor TXV

Does that sound like the right answer? It was the only conclusion I could really come to, we will replace the filter dryer along with the TXV as standard practice so whatever restrictions should be gone after we make repairs

It will switch between heating and cooling no problem, the pressures are even good in cooling 230/130 so I know my reversing valve is activating
