Home Heating Repairs

At London Boiler Service, we understand the importance of a well-functioning home heating system. As the cold weather sets in, having a reliable and efficient heating system becomes essential for maintaining a comfortable living environment. However, like any other appliance, heating systems are prone to issues and malfunctions. In this article, we will discuss the different types of home heating systems, common problems that can arise, troubleshooting tips, and when to call a professional for assistance.

Types of Home Heating Systems


Furnaces are one of the most common heating systems found in homes. They work by producing heat through the combustion of fuel, such as natural gas or oil, and distributing it throughout the house via ducts and vents. Furnaces are known for their effectiveness in quickly heating up a space and providing constant warmth.


Boilers, on the other hand, use water as a heat transfer medium. They heat the water and distribute it through pipes to radiators or underfloor heating systems, providing warmth throughout the house. Boilers are known for their efficiency and are particularly popular in areas where extremely cold temperatures are common.

Heat Pumps

Heat pumps are a more energy-efficient alternative to traditional furnaces or boilers. They extract heat from the outside air or ground and transfer it inside the house using a refrigerant cycle. Heat pumps provide both heating and cooling functions, making them versatile and cost-effective.

Electric Heaters

Electric heaters are often used in smaller spaces or as supplemental heating sources. They convert electrical energy into heat and distribute it through radiant heating panels, baseboard heaters, or forced air systems. Electric heaters are easy to install and require minimal maintenance.

Common Heating System Issues

Even with regular maintenance, heating systems can experience problems over time. Here are some common issues that homeowners may encounter:

No Heat

One of the most common and frustrating problems is a complete loss of heat. This can be due to a variety of reasons, such as a malfunctioning thermostat, a faulty ignition system, or a lack of fuel supply.

Insufficient Heat

Another issue homeowners may face is insufficient heat output. This can be caused by dirty air filters, blocked vents or ducts, or low fuel supply. If certain areas of your home are not receiving adequate heat, it could be a sign of an underlying problem with the distribution system.

Strange Noises

Unusual noises coming from your heating system, such as banging, clanking, or whistling, could indicate a mechanical problem or a loose component. It is important to address these strange noises promptly to prevent further damage.

High Energy Bills

If you notice a sudden increase in your energy bills without any changes in your usage patterns, it could be a sign that your heating system is working inefficiently. This could be due to a variety of reasons, including a faulty thermostat, poor insulation, or a malfunctioning component.

Troubleshooting Home Heating Problems

While some heating system issues require professional assistance, there are a few troubleshooting steps you can take before calling for help. Here are some tips:

Check the Thermostat

Start by checking the thermostat settings. Make sure it is set to “heat” mode and the temperature is set higher than the current room temperature. If the thermostat is battery-powered, replace the batteries and ensure it is functioning properly.

Inspect the Air Filters

Dirty air filters can restrict airflow and reduce the efficiency of your heating system. Check the filters regularly and clean or replace them as necessary. Clean filters promote better air quality and improve the overall performance of the system.

Check the Fuel Supply

If you have a furnace or boiler that uses fuel (such as gas or oil), ensure that the fuel supply is not interrupted. Check the supply valves to make sure they are open and the fuel is flowing properly. If you suspect a fuel leak, it is best to call a professional immediately.

Inspect the Ignition System

For furnaces and boilers, a faulty ignition system can prevent the heating system from starting. Check for any visible signs of damage or wear on the ignition components. If you are unsure or uncomfortable performing this inspection, it is recommended to consult a professional.

DIY Home Heating Repairs

While some repairs are best left to professionals, there are a few simple repairs that homeowners can do themselves. Here are some examples:

Replacing a Faulty Thermostat

If your thermostat is not functioning properly, it may need to be replaced. Before attempting this repair, ensure that you have the necessary tools and knowledge to do it safely. Follow the manufacturer’s instructions carefully to avoid any damage or electrical hazards.

Cleaning or Replacing Air Filters

As mentioned earlier, dirty air filters can negatively impact the performance of your heating system. Regularly clean or replace the filters according to the manufacturer’s recommendations. This simple maintenance task can greatly improve the efficiency of your system.

Bleeding Radiators

If you have a hot water heating system with radiators, trapped air can hinder efficient heating. Bleeding the radiators will release any trapped air and allow hot water to circulate freely. Consult your system’s manual or seek professional guidance to ensure a safe and effective process.

Resetting Circuit Breakers

In the event of a power surge or electrical malfunction, your heating system’s circuit breaker may trip. Check the circuit breakers and reset any that have been tripped. However, if the breakers continue to trip repeatedly, it may indicate a larger electrical issue that requires professional attention.

When to Call a Professional

While DIY repairs can be cost-effective and empowering, there are several situations where it is best to call a professional heating repair service. Here are some instances:

Gas Leaks

If you smell gas or suspect a gas leak in your home, it is crucial to evacuate immediately and contact your gas company or emergency services. Gas leaks are extremely dangerous and should only be handled by trained professionals.

Electrical Issues

If you experience electrical problems, such as a blown fuse, sparking wires, or frequent circuit breaker trips, it is best to leave the repairs to a licensed electrician. Electrical issues can be hazardous and require specialized knowledge to resolve safely.

Complex Repairs

Some heating system repairs, such as fixing a malfunctioning heat exchanger or replacing a faulty control board, require technical expertise and specialized equipment. These complex repairs should be left to experienced professionals who have the necessary skills and tools.

Uncertain Diagnosis

If you are unsure about the cause of your heating system’s problem or if your attempts to troubleshoot have been unsuccessful, it is advisable to seek professional assistance. A trained technician can accurately diagnose the issue and provide appropriate repairs.

Get Multiple Quotes

Before making a final decision, obtain multiple quotes from different heating repair services. This will allow you to compare prices, services offered, and warranties provided. However, keep in mind that the cheapest option may not always be the best choice.

Ask for Warranty

Inquire about the warranty offered by the heating repair service. A reputable company should provide a warranty on their workmanship as well as any parts they replace. This will give you peace of mind knowing that you are protected if any issues arise after the repair.

Cost of Home Heating Repairs

The cost of home heating repairs can vary depending on several factors. Here are some considerations to keep in mind:

Factors Affecting Repair Costs

The type and complexity of the repair, the age of your heating system, the availability of replacement parts, and the service provider you choose can all impact the cost of repairs. Additionally, emergency repairs may incur higher costs due to after-hours service charges.

Heat pump repairs typically fall in the $250 to $500 range, and electric heater repairs can range from $100 to $300. These are ballpark figures and can vary depending on the specific issue.

Budgeting for Repairs

It is always a good idea to budget for unexpected repairs by setting aside a portion of your monthly household budget. This way, you are prepared for any unforeseen repair costs that may arise.

Considering Replacement as an Alternative

In some cases, it may be more cost-effective to replace an older or inefficient heating system rather than investing in frequent repairs. Consult with a heating professional to determine if replacement is a more viable option for your specific situation.

Preventing Future Heating System Issues

While repairs are sometimes unavoidable, there are measures you can take to minimize the likelihood of future problems. Here are some preventative steps:

Regular Maintenance

Schedule regular maintenance for your heating system to ensure it is functioning optimally. This includes cleaning or replacing filters, inspecting and lubricating components, and checking for any signs of wear or damage.

Proper Insulation

Proper insulation helps to retain heat within your home and prevent warm air from escaping. Insulate windows, doors, and walls, and seal any drafts to maximize the efficiency of your heating system.

Monitoring Energy Usage

Be mindful of your energy consumption and make efforts to reduce unnecessary usage. Lowering the thermostat when you are away or installing a programmable thermostat can significantly reduce energy costs.

Upgrading to Energy-Efficient Systems

Consider upgrading to a more energy-efficient heating system. Energy-efficient options not only reduce your carbon footprint but also save you money in the long run through lower energy bills.

Safety Tips for Home Heating Systems

It is important to prioritize safety when it comes to home heating systems. Here are some safety tips to keep in mind:

Carbon Monoxide Safety

Carbon monoxide (CO) is a silent and potentially deadly gas that can be emitted by malfunctioning heating systems. Install carbon monoxide detectors in your home and ensure they are functioning properly. Also, never operate heating systems in enclosed or poorly ventilated areas.

Fire Safety Precautions

Keep flammable materials away from heating equipment and ensure that heating systems are clear of any obstructions. If you have a fireplace or wood-burning stove, have the chimney cleaned and inspected annually to prevent chimney fires.

Proper Ventilation

Ensure proper ventilation for fuel-burning heating systems to prevent the build-up of harmful gases. Blocked vents can cause a backdraft, leading to a dangerous concentration of combustion byproducts in your home.

Gas and Electric Safety

If you have a gas heating system, be aware of the location and operation of the gas shut-off valve. If you smell gas, do not use any electrical appliances, turn off the gas supply, and contact your gas company immediately. For electric heating systems, be cautious with electrical cords and outlets to prevent electrical hazards.


Maintaining a well-functioning home heating system is essential for a comfortable living environment, especially during the colder months. While some repairs can be tackled by homeowners themselves, it is crucial to know when to call a professional to avoid further damage and ensure safety. By following preventative measures and scheduling regular maintenance, you can prolong the lifespan of your heating system and avoid major repairs. Stay warm and cozy this winter with a reliable and efficient home heating system.
