At Leonard Splaine, we understand the importance of a well-functioning boiler system in your Northern Virginia home. A boiler is a vital component of your heating system that provides warmth and comfort to your living space. In this page, we'll explore what a boiler is, why it's crucial, how it works, signs that your boiler might need repair, and the cost of boiler repair.
A boiler is a specialized heating appliance designed to generate hot water or steam for heating and various other domestic or industrial applications. Boilers come in different types, including combi boilers, Standard efficiency natural vent boilers and high efficient direct vent boilers, each with its unique features and functions. They are typically powered by natural gas, oil, or propane and electric.

Signs Your Boiler Needs Repair
Boilers, like any mechanical system, can develop issues over time. Here are some common signs that your boiler may require repair:
- Strange Noises
Unusual banging, whistling, or gurgling sounds from your boiler can indicate underlying problems. - Inefficient Heating
If your home isn't warming up as it should, or some rooms are colder than others, your boiler might not be operating optimally. - Frequent Breakdowns
Frequent breakdowns or the need for constant adjustments can be a sign of a boiler in need of repair. - Increased Energy Bills
A sudden spike in your energy bills without changes in usage could indicate boiler inefficiency. - Leaks or Drips
Visible water leaks around the boiler or pressure loss issues need immediate attention. - Yellow or Orange Pilot Light
The pilot light should be blue. A different color could indicate a carbon monoxide issue.
How Much Does a Boiler Repair Cost?
The cost of boiler repair can vary depending on several factors, including the type and age of the boiler, the extent of the damage or malfunction, and your location.
It's essential to have your boiler regularly serviced to prevent costly breakdowns and maintain its efficiency. At Leonard Splaine, our team of experienced professionals specializes in boiler repair, maintenance, and installation. We are committed to ensuring your home stays warm and comfortable all year round.
Types of Boiler Repair
Boilers can require various types of repairs to ensure they operate efficiently and safely. Here are some common types of boiler repairs:
Safety & Efficiency
This type encompasses essential boiler repairs that focus on ensuring the safety and efficiency of the heating system. It includes leak repairs, pressure issues, ignition and pilot light repairs, heat exchanger repair, circulator pump repair, expansion tank repairs, and safety valve replacement. These repairs are crucial for maintaining the boiler's safety, preventing water damage, and optimizing its performance.
Temperature Control
This is dedicated to maintaining temperature control and comfort within the environment. This includes thermostat replacement, combustion adjustment, and electrical component repairs. Malfunctioning thermostats can lead to temperature issues, while combustion adjustment and electrical component repairs ensure that the boiler operates at its best, maintaining an optimal and consistent temperature.
System Integrity
This deals with overall system integrity and functionality. It involves pipe and radiator repairs, ventilation and flue repairs, cleaning and maintenance, and gas or oil supply issues. Ensuring that pipes, radiators, and the fuel supply system are in good condition prevents heat loss and malfunctions while cleaning and maintenance keeps the entire system running smoothly. Ventilation and flue repairs are vital for safe operation and preventing carbon monoxide leaks.
It's important to note that boiler repairs should be carried out by qualified professionals to ensure safety and effectiveness. Regular maintenance and addressing repair needs promptly can extend the lifespan of your boiler and keep it operating at peak efficiency.

Furnace Heating Systems in Northern Virginia
A furnace is an appliance that produces heat to supply warmth to a building. This is accomplished by combusting fuel such as gas or oil, or passing electricity through resistive heating elements.
It is totally different from a heat pump, which transfers heat from outdoors into the building. If your home heating system is linked to an outdoor unit with a fan, but doesn’t include an air conditioner, then it is a heat pump and requires different maintenance than a furnace.
A furnace can provide a reliable source of heat for your home, however if it is not functioning optimally it can not only put your comfort at risk, but also your safety.
When your furnace breaks down, it can create a number of problems, particularly in the colder months. Besides the discomfort of being inside an icy home, the possibility of your pipes freezing and bursting is also a very big concern. That is why Leonard Splaine & co is available 24/7 – even on weekends and holidays.
Signs Your Furnace Needs Repair
For a furnace to work properly, motors, sensors, igniters, gas valves, fans, flame rectification systems, controls, and bearings must all be in good condition. If one of these components is faulty, it can result in the entire system malfunctioning. This is why regular maintenance is so important.
A furnace is a complex machine composed of many components which must all work together in order for it to operate correctly. If one part is not functioning properly, the entire system can cease to function.
Possible causes for a furnace to shut down prematurely include a faulty flame sensor, which can prevent the gas valve from being activated, as well as a clogged flue pipe/exhaust vent. If dirt and debris accumulate and block the flue pipe, it can lead to overheating of the furnace, resulting in a safety mechanism kicking in and shutting it down.
Signs are usually indications or warnings that something is about to happen. Before you find yourself suddenly stuck in a cold house during winter, keep an eye out for the following warning signs your furnace needs repair.
- Abnormal furnace smells
- Persistent and disconcerting noises
- Poor air quality
- Short cycling
- A tripped carbon-monoxide detector
- A discolored pilot light
- Inadequate heat/airflow
- It won’t turn on or off
We'll look at each of these signs in more detail below:
Odd Smell Coming from Furnace
The subtle odor of fuel is not necessarily a concern, because Furnaces can smell like the fuel that they use, especially when they are turned on for the first time in a year. However, if there is a strong smell of fuel, an unexpected smell, or one that doesn't dissipate, then it could be an indication of a gas leak or dust buildup in the unit. Our HVAC experts can inspect the system to identify the source of the smell.
Persistent Noises
The functioning of furnaces usually creates some noise, however, if you hear any noise that is out of the ordinary, persistent and disturbing, it may be an indication that there is an issue. Our HVAC experts are familiar with the connection between certain furnace issues and the sounds they make, so if you hear something strange coming from your furnace, it's best to get in touch with us.
Some of the likely sounds you could hear from your furnace and their possible causes are:
- Squealing noises often result from belt or fan issues
- Banging or groaning noises can be caused by loose internal parts
- Scraping noises usually mean warped fan blades and/or a broken motor
- Thumping noises might indicate an imbalanced blower wheel
- Unusually loud or prolonged rumbling may arise from a faulty gas valve
- Rattling noises could mean the metal housing fasteners are loose
- Clanking noises often occur when debris gets stuck in a compressor or fan
- Popping noises often result from ductwork sheet metal reacting to air pressure variations
- Hissing noises may be air escaping from a loose air filter, a partially obstructed vent, or leaky ductwork
- Whistling noises may signal a refrigerant leak in the condenser
Poor Air Quality
Maintaining a clean and well-kept furnace system can have a significant effect on the quality of indoor air. If a furnace is neglected or not cleaned properly, allergens, bacteria and other particle-containing air can be spread through the heated air, leading to illnesses, respiratory issues and allergic reactions such as itchy eyes, watery eyes and headaches. Fortunately, many air quality issues can be remedied through simple steps such as changing the air filter, cleaning the ductwork, and dusting the unit.
Difficulty Starting
As a furnace gets older, you could have more difficulty starting and maintaining the appliance. You probably need a repair if you have to restart your furnace or try to start the appliance several times during the day.
Thermostat damage or disconnected wiring are common causes of these functioning problems. The problem should be resolved by replacing the damaged component.
Inadequate Heat
A tell-tale sign that your furnace is in need of repairs is if it is not adequately heating your home. If you notice that no heat or only low levels of heat are coming through despite the thermostat being set, it's time to schedule repairs. Possible causes are leaks in the ductwork that allow the treated air to escape and a malfunctioning thermostat that does not correctly transmit the necessary signals to the furnace.
Discoloured Pilot Light
Pay close attention to the hue of your pilot light. Generally, if the flame is blue, it is in good condition. However, if the light changes to yellow, it may be a sign of a venting issue. This could be dangerous as the emission of carbon monoxide may be impeded and can lead to health risks for you and your family, as well as increasing the chances of combustion.
Carbon-Monoxide Detection
Your furnace is equipped with a carbon-monoxide detector that is meant to signal you if poisonous gases are present. If the alarm is triggered, immediately switch off the furnace and open the windows to provide ventilation for your residence. It is advised to consult the gas campany and an HVAC worker to identify the origin of the gas. Do not postpone if you spot any of the indications mentioned above, schedule an assessment and the necessary repairs as soon as possible.
Unexpected Increase in Energy Bills
If you're finding yourself paying higher electricity bills than usual, it may be due to an inefficient furnace that's working overtime in order to provide adequate warmth. If you notice your heating system is running constantly, contact us. We can help you lower your energy expenses by replacing your existing unit with a more energy-efficient option, such as a heat pump or ductless system.

How Much Does a Furnace Repair Cost?
Furnace repairs can be daunting, especially if you don’t know what to expect. There are many factors to account for when estimating furnace repair costs, including:
- Type of repair needed
- Type of furnace you own
- Type and validity of warranty
- Age of furnace
- Contractor you hire
We’ll break down the details of each of these cost factors to help you better determine how much your furnace repair may cost you.
Type of repair
Due to the variety of components that furnaces contain, it is hard to estimate the cost of a repair until a certified technician can assess the issue. For instance, if the furnace doesn't begin when you turn it on, any of the numerous components could be the reason for this malfunction.
- A broken thermostat
- A dirty air filter
- A dirty flame sensor
- A faulty gas valve
- And much more...
For every issue with your furnace, there is an associated cost. It is difficult to determine an accurate price for the repair without first examining the furnace. Therefore, be cautious if a HVAC company offers to give a price quote over the phone without examining your furnace.
Type of Furnace
Gas furnaces are typically more expensive to fix than electric furnaces due to their intricate internal components.
These components are generally more complex than those in electric furnaces and require more time and effort to repair.As the illustration of a gas furnace earlier in this article showed, a gas furnace is a complex system with quite a number of components and systems. As such, repairs to such a system can be more costly.
Whether It's Still Under Warranty
If your labor warranty or parts warranty is still valid, the cost to repair your furnace could be fairly inexpensive.
Two types of warranties you might have are:
Labor Warranty
Most companies/contractors offer a minimum one-year labor warranty on their furnace installations which covers the cost of labor to fix it if there is a problem with the installation. In addition, they usually offer warranties on repairs as well, but these are usually limited to the repair itself, for instance a 90-day warranty for a thermostat repair will include only the same issue that was previously fixed.
Parts Warranty
The manufacturer of your furnace (Trane, Carrier, Lennox, etc) typically covers a parts warranty for any malfunctioning components due to manufacturing problems. This warranty usually lasts up to 5 years, while extended warranties may range from 7-15 years.
Additionally, some manufacturers offer lifetime warranties for heat exchangers.
It is important to remember that in order for the warranty of your parts to stay valid, an annual maintenance by a professional is necessary. If you haven't kept up with the maintenance of your furnace, it is likely that the warranty is invalid.
Age of Furnace
Depending on the age of your furnace, you might be able to avoid costly repairs by restoring it. Restoration can be a great choice for furnaces with worn or stressed-out components, or ones that are showing signs of wear.
Basically, this kind of work can help a furnace that has not broken down yet, but is in danger of doing so. Restoration is often pricier than just making repairs, but it is cheaper than replacing the furnace altogether. If your furnace is aging and starting to wear out, expensive repairs could be on the horizon, and a restoration may be the most cost-effective approach.
Your Repair Contractor
The old adage “You get what you pay for” is especially pertinent when considering which contractor to hire for a furnace repair.
Generally, the more highly qualified and experienced the contractor is, the higher the cost for their time and services.
Rather than settling for a bargain-basement contractor, it's important to find one who possesses the necessary knowledge, skill and expertise to do the job properly and efficiently. After all, it's not worth risking the potential consequences of an inferior job.
Signs It’s Time to Buy a New Furnace
It's essential to monitor your furnace regularly to be aware of when it's time to replace it. Paying special attention once the furnace has exceeded its planned lifespan is very important since this may indicate that you'll need to change it sooner than expected.
Here are some signs that you should replace your furnace:
Frequent Repairs
At some point, your furnace may require repairs due to typical wear and tear. If you have your heating specialist come in for annual maintenance, you don't need to worry.
However, if you have to call them in more and more often, it might be time to consider purchasing a new furnace. Maintenance on a furnace that is not functioning efficiently can become expensive, so it would be beneficial to have one of our technicians install a new system for you.
Aging Furnace
How long have you owned your current furnace? If it is older than 15 years, its age is a sign that you ought to think about getting a new one. Even the best furnaces can't last more than 15 years, no matter how well you look after them. Therefore, you should be aware of the age of your heating system. When you realize it is getting on with age, consider replacing it.
Older furnaces tend to become less efficient as time passes. This means that it will run for longer than usual in order to heat your home, leading to higher power bills. In the long run it's more cost effective to replace your furnace when you start to see a decrease in efficiency.
Most furnaces come with a manual that states how long they can be expected to last. Furthermore, you can talk to an expert to get a better understanding of your furnace's lifespan. This information will help you make plans to get a new furnace before the end of its life expectancy. You don't want your furnace to break down in the middle of winter when you need it most.
High Energy Costs
Having a gas or electric furnace in your home can prove to be a money-saving investment. If your furnace is in good working condition, it won't take much energy to maintain a comfortable temperature throughout the winter. However, if your energy costs seem to be increasing abruptly at the end of each month, it's time to have your furnace inspected.
If there is an issue with your furnace, it will use additional energy to maintain the set temperatures, resulting in increased utility bills. To avoid this, you should replace the furnace with an energy-efficient model that will help you to save money in the long run.
Furnace Installation & Replacement Services
During the colder months, having a functional furnace can make all the difference in keeping your home warm and cozy. Unfortunately, like any other appliance in the house, you may experience a malfunctioning heating system that needs to be replaced. Look out for the signs listed above to help you determine when it’s time to replace your furnace. It is important to keep in mind that furnace-related issues can cause serious health concerns such as carbon monoxide poisoning, mold, and other air pollutants.
