The usual suspects
Cold radiators with a hot boiler almost always mean a distribution fault rather than a heat-making fault. Pressure that climbs then dumps means the expansion tank. Banging in steam means water sitting where steam needs to travel.
Heating and cooling around Londonderry
Around Londonderry the fuel is usually natural gas, though propane turns up wherever the main stops short. What makes Chester County distinctive is the age of the buildings: stone farmhouses and pre-war homes that were designed around radiators and later had ductwork threaded through them.
Those retrofits are behind a lot of the comfort complaints we are called about — rooms that never settle, and a system blamed for duct problems.
What happens when you call
Every technician working Londonderry under the Plumsteadville HVAC Pros name follows the same sequence Frank Reilly used on his own in 2014: find the fault, price it, agree it, fix it.

Boiler Repair in Londonderry — questions
Do you cover Londonderry for boiler repair?
Yes. Londonderry in Chester County is inside our service area and the 19330 postal area is worked by the nearest crew. Call (215) 484-0300 at any hour, including nights, weekends and holidays.
My radiators are cold but the boiler is running. Why?
The boiler is making heat but something is stopping it reaching the radiators — air in the loop, a failed circulator pump, or a zone valve stuck closed. If bleeding helps for a day then stops, air is getting in somewhere.
Is a 40-year-old boiler worth repairing?
Often yes. Cast iron blocks last, and pumps, valves, controls and vents are replaceable. What is not repairable is a cracked or weeping block, and we will tell you which situation you are in.
What pressure should my boiler run at?
Most residential hot water systems sit near 12 psi cold and rise as the water heats. Steam runs far lower. If yours keeps dropping, something is losing water and that needs finding rather than topping up.
