Main Heat Pump buuumr on heat
Our main or primary heat pump, started a noise like buuuum on heat the other night and still does it until the compressor cuts out.
How bad is it and can I fix it?

Then you have another part causing the noise. What is the Outside ambient temp when running in Heat Mode? Doug- Doesn't do it on cool.
- Does it Heat? The compressor will make the same noise in COLD mode also. When on AC mode, does the compressor make the same noise? And, does it cool? Doug
- Quite likely it is the capacitor and capacitors are easilly replaced. The bottom will be bulged out if it is bad. The bottom should be flat. There should also be a sticker on it telling you what size it is and it is important to get the same size (electrical rating). If you are able to do it yourself do it, otherwise be prepared to pay a couple hundred bucks for someone else to do it, a capacitor should only cost about 20 bucks or less. Google is your friend in this, look up how to do it.
- Check the capacitors. If they look in the least bit bulged or messy, replace them. Their the main reason a compressor will not start as it should. Don't let it keep trying to start or you'll ruin it for good.
