It is probably a rotary compressor unit.
They tend to make a start up noise.
Some technicians advocate adding a booster starting device to help the compressor start more quickly, thereby reducing startup noise.

3 ton heat pump with piston in air handler. After unit shuts down it makes loud fluid flow noise for about 2 minutes


adding a tvx will not help. the sound you here is the pressure equalizing and that has got to happen for the compressor to start again the next time. A tvx will give you a higher efficiency because it can adjust to changing temperature conditions. Only way i know to quiet the noise is to try to insulate the lines better.

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

I have a 10 SEER heat pump about 16 years old, yesterday I notice that the outside unit was making a loud click noise in the heating mode. It's very close to the defrost electrical curcuit board. The unit...


Depending on make and model sounds like a check valve clicking. It can sound like it is coming from that area. You say your unit is 16 years old. Honeywell did servey on unit 10 years and older and found out they loose 25% effeicency after 10 years. You may think about changing it out. With the new tax credits you can get a 16 seer unit for the price of a 13 seer. I went from a 10 to 15 seer and my power bill dropped 40%. Rus.

Just had a new 3.5 Ton Goodman GSZ13-13 SEER, heatpump installed. Its working OK in Cooling, however whe switched over to heating mode the indor unit makes a loud grumbling sound. The installer stated that...


I install them every day and I have not had one make a loud grumbling sound. Sounds like you might have a low voltage (Thermostat) wiring problem. The only thing different inside the indoors unit from heat and cool is the fan speed, electric heat when on. The fan might be loose or out of balance and it only shows up at low speeds. Either way, the noise is not normal.

New 14 seer split ruud heat pump makes very loud knocking noise


Well you may want to have a tech come out and check the freon level, but mostly when going into defrost, some units make alot of noise, the freon is reversed in the unit by way of the reversing valve, it makes a whooshing sound like freon is draining off, as far as the knocking noise, could be as I said in the beginning, might be low on freon, but it could be that, this particular unit does this, I have had units make some really strange noises in the past but functioned perfectly, hope this helped, please let us know, thanks again,
mr.grzz
