Question about Air Conditioners
I assume this is hotwater heating. Your problem is air in the line. You may have something called an airscoop at the boiler...it is attached to a pipe at the top of the boiler and has a radiator vent unit on top. Purge it and you may fix your issue...or not.
If you don't have one or the problem persists, you'll have to bleed all of the radiators...perhaps several times. Be sure when you're doing this that you have water in the boiler before and after. If you fire a dry boiler, this is a problem which will be very expensive. You should see about 15 PSI or so of pressure indicating on the gauge. If you see less than 10 or more than 25, you also have a feed valve issue. These things do get dirty and they do clog.
If your vent valves at the radiators are more than 10 years old, get replacements. Take a couple of pictures of them and go to the plumbing store. Turn the water to the boiler off and quickly change each one. Turn the water back on, bleed again and you will be fine.
