I've been in this house for over 30 years. Only this year the heating system is chugging and gurgling a lot. I had my heating contractor come out and he supposedly drained, purged and recharged the pipes and a week later... same noises.
I would like to resolve this but I would like to know if there is anything I can look for or correct myself or at least be able to explain to someone what to look for.
So, please, any who may know what to look for or perform... respond away?
Thanks (and stay warm if you're in the NorthEast)
