Pressure is usually 12 instead of 22 on a single story house.

The house is three story, with three zones (two small apartments), and the house has the main level, and bedrooms upstairs. I have had problems with registers working since the installation The upstairs bedrooms weren't getting heat. The company keeps turning up the pressure, I think that is what I believe they keep doing to try and solve the problem. I am wondering if something isn't hooked up correctly. The installer is baffled at why the heat isn't working in all the registers. It was professionally installed, and it's a small island in Alaska with basically one company on our island. They will work upstairs, but not downstairs, and visa versa. The apartments are getting heat, but said they can hear bubbling in the radiators. They were all bleed on the installation from my understanding. Any suggestions

Now we have more of the story to work with.

Have them install automatic bleeders at the highest point in the system.
Just because it was bleed at start up when new does not mean no more air got in the line.

Use this adapter and 1/4 inch copper tube for attic or any install when safet water venting is absolutely needed. If the vent gets plugged up and wants to leak this little item prevents that from happening by running any overflow from the valve to the outside of the house. I have them but they never have had to be used in over 30 years. I just consider it insurance fror leaks.
