New outside compressor 4 ton Ruud 13 seer unit.

My total a/c system ( outside compressor and inside air handler ) was replaced just over a year ago just over the 1 year labor warranty. The outside compressor unit makes a loud bang sound when it cycles off. I have had the motor and capacitor unit along with another part replaced when the unit just stopped running completely and all of a sudden.

Please advise what you think the problem is and is it another big problem just waiting to happen???

Sounds like a compressor needs to be replaced. You will need a service tech to make sure of it. Sometimes the compressor can work for a long time that way. Check your warranty. Usually compressors will have longer warranty on it.

Going to replace hvac system. Don't know what


Hello,
According to the model number it is a 2 ton or 24,000 BTU unit. It is very important that you change the indoor coil as well as the outdoor section, due to it being a 10 SEER unit, and the new basic systems are 13 SEER, the old coil cannot handle the higher SEER ratings.
Rheem and Ruud are the same equipment, just 1 number different on the model number.
I hope this has helped, please rate the new guy :)
Please contact me if I can be of any further help to you.
Have a great day!
Sincerely,
Paul Gibson

2 month long issue...RUUD Achiever 1.5 Ton 10 Seer Heat Pump


Rather than have him replace the control board first, ask him to remove all the freon and weigh it. He then can reuse the Freon that came out of your system put back in at the exact charge that the rating plate calls for. He will add a bit more to compensate for any length of refrigerant lines from the outside unit to the inside unit. Now this will bring us to factory specs. If the unit continues to act up, then try another board. I am not a big fan of replacing parts unless other alternative ways have been tried. If he is not willing to try what you ask, why is he there? As far as if something is taking out the control board, have him clean and reconnect all ground connections and inspect the thermostat connections both on the inside unit and the outside unit. Is lightning a factor in your area?

Is there a system mismatch with an American Standard 13 seer 3 ton compressor and a Nordyne 3.5 ton air handler? Noise at TRV when heating.


This must be a heat pump? Sometimes the unit can be more efficient with this combonation. What you are probably hearing is the reverse direction of the
refrigerant going back through the liquid line.

If in cooling sometimes you can hear a gurgling sound going through the expansion valve, sometimes
this is a sign of low refrigerant or the system is fine..

If you recently had the outdoor unit replaced and noise is an issue, check to see if the unit has isolation pads installed underneath the unit whether
it be on concrete slab or on brackets mounted to
house. Sometimes the new units come with compressor that has a jacket installed over it

Just had the haier 4 ton 13 seer outside unit installed. my inside unit is a payne and still in good condition.had a 4 ton 10 seer outside unit previously. my problem is the unit froze up the first night...


Your problem is that your 13 seer outdoor unit is not compatible with your 10 seer indoor unit, even though the tonnage is the same. The metering device on 13 seer indoor units is different. Most 10 seer indoor units do not have an expansion valve. When you change from a 10 seer outdoor unit to a 13 seer outdoor unit, you must, at the very least, change the from a fixed-orfice metering device to an expansion valve.

WEATHERKING 10AJA4801 BAD COMPRESSOR


You have 10 seer 4 ton unit. A compressor install in my company (4 ton) is about 1400 dollars. Remember when you change compressor you only get a 1 year warranty. A new unit can have as much as 10 year compressor warranty. Amana has a 10 year parts and labor with their unit. The new unit will be 13 seer and you may have to install a TXV inside. You might think about changing the whole system with the new 410A system. Either way a new condensing unit is needed. I have not had anyone just change a compressor in an older unit. Just not cost effective. Get several estimates before you make up your mind. Rus

Ruud heat pump question


Does the air handler take a minute or two to start, this would be normal so that it doesn't blow cool air into the house before the unit is warmed up. If not could be the fan relay is weak and needs replacing. As far as the outside unit it sounds like you need to check the refrigerant. In cooling they are 70/150 psi. This should be checked in cooling mode, once you turn it to heating mode the pressures switch bring heat inside the house instead of out. I hope this helps.
