Boiler Repair questions, answered by experts

Your house may be cold even if the heat is on because of bad insulation, gaps in doors, small holes pulling hot air from the home, or excess humidity. The heater itself might be malfunctioning. For this problem, you’d need to talk to an HVAC pro. If you have a gas heating system (most do) this should be considered an urgent job as natural gas could be leaking in your home.

Blockages can occur for various reasons, primarily linked to the accumulation of debris or substances within the heating system. Common causes include the buildup of sediment, rust, or mineral deposits inside the boiler or its pipes, hindering water flow and heat transfer. Additionally, air pockets or trapped gasses can impede circulation. In central heating systems, sludge or corrosion within radiators can obstruct the flow of hot water. External factors like frozen pipes in winter can also lead to blockages. Regular maintenance will help prevent blockages and ensure efficient boiler operation.

With proper maintenance, boilers last for around 15 years on average. A cast iron boiler may last longer, over 20 years, but you should always consider the efficiency of older boilers and opt to replace an old one if it’s significantly lower than newer, high-efficiency boilers. Otherwise, you’ll be spending more on your utility bills each month.

Repair costs typically range from $200 to $1,500, depending on the issue, such as leaks, burner malfunctions, or thermostat failures. Complex repairs involving heat exchanger replacement can be more expensive.

The difference between a heat pump and a boiler is simple. A boiler often works with a furnace as part of a heating system. Some HVAC systems also have an AC to cool the home in addition to a boiler. A heat pump is unique as it works as both a heating and cooling system, altering ambient air to a comfortable indoor temperature.
