Neighbors, you have given us so many great service recommendations in the past two years that I have come back again. Need a good recommendation for a company to give our gas furnace & radiators a tune-up before winter. I think there might be an air block or two in the pipes. We also have a gas fireplace that we haven't used since we moved in, that I would like to be checked out for quality/safety before we light the pilot light. Thanks in advance!
