The Centreville area in Virginia receives an average of 21 inches of snow on an annual basis. While this may not be as high as the national average of 27 inches of snow, it’s still vital to purchase a high-efficiency furnace to keep your home comfortable during the winter season. Since a gas furnace is engineered with a large number of parts and components, it is nearly impossible for an average homeowner to diagnose and resolve moderate to advanced furnace problems.

The temperatures in Centreville are able to drop as low as 23 degrees Fahrenheit during the month of January. If the furnace in your home breaks on a cold day, this may jeopardize the health of your kids and family. Performing continuous repairs and tune-ups to your furnace will help protect your kids from the common cold, flu, and other illnesses. Prior to calling a professional heating contractor, it’s important to familiarize yourself with how a gas furnace operates to ensure you’re able to ask the correct questions during the furnace repair service appointment.

Furnace Tune-Up Services in Centreville, VAHow a Gas Furnace Operates

The gas furnace in your house is connected to a central thermostat that is designed to regulate the operational schedule of the heating system. Once a thermostat detects the interior temperature of the home is below a programmed setting, it will send a signal to activate your gas furnace. When the furnace receives this signal, an interior gas valve is opened to ensure gas is able to be pushed to the burners.

Depending on the type of gas furnace in your house, a standing pilot light or electronic ignition system is utilized to ignite the gas burners within the combustion compartment. Next, a sufficient supply of warm air is created within the heat exchanger of the gas furnace. Once the interior air supply reaches an optimal temperature, it will travel to the plenum prior to reaching the air ducts in your home.

Depending on the severity of the issues with your gas furnace, our team of technicians may recommend investing in a new energy-efficient gas furnace. Unlike traditional gas furnaces that rely on a continuous pilot light, the latest gas heating systems on the market utilize electronic ignition methods such as hot surface ignition systems and intermittent pilot lights. Our team of certified technicians offers dependable furnace and air conditioning repair services to homes in Centreville, VA and other areas. Our team will perform an inspection of your pilot light or hot surface ignition system to diagnose and resolve the issue.

Types of Gas Furnace Ignition Systems

Old gas furnaces are built with a small standing flame that is always on throughout the day. This flame or pilot light is utilized to create a reaction with incoming gas as it travels to the burners of the furnace. These types of pilot lights are no longer used with the latest gas furnaces because they were susceptible to failure. Common causes of pilot light issues include a cracked heat exchanger, malfunctioning thermocouple, and wind.

Hot Surface Ignition Systems

Most gas furnaces that are available include a hot surface ignition system that relies on electricity to produce warm air. This type of system features filaments that are almost identical to a light bulb. Once the gas furnace receives a command from the thermostat to activate a new heating cycle, electricity is used to increase the temperature of the filaments.

After the filaments reach a programmed internal temperature, the gas valve is opened to provide gas to the burners of the furnace. The hot filaments of the electronic ignition system are engineered to ignite the gas in the burners of the heating system. Since a hot surface ignition system relies on pure electricity, it is energy efficient.

Furnace Intermittent Pilot Light

Another type of electronic ignition system that is utilized on the latest gas furnaces is an intermittent pilot light. While older gas furnaces rely on a pilot light that is kept on all day, newer furnaces use a spark to activate the pilot light when at the beginning of the standard heating process.

An intermittent pilot light features a small valve that is opened at the beginning of the combustion process. Next, a small electric spark is used to activate the pilot light in the furnace. Once the pilot light is on, a gas valve is opened to ensure the burners receive enough fuel to produce warm air.

To save energy and money, the intermittent pilot light is shut off while the furnace is activated. If you need help fixing an intermittent pilot light, give our technicians a call at (703) 543-9649. Snell Heating & Air Conditioning provides affordable gas furnace repair and installation services to homeowners in Centreville, Virginia.

Electric Furnace Tune-Up, Repair, & Installation Services

If you’re searching for new furnaces for your house, you may be debating about purchasing an electric furnace instead of a gas model due to the attractive price tag. While electric furnaces may cost less to purchase, this type of system will cost more to operate each month when compared to gas furnaces.

On the other hand, you may want to consider investing in an electric furnace if you’re looking for a long-term heating solution. An average electric furnace features a lifespan of 20 to 30 years while a gas furnace includes a lifespan of 10 to 20 years. However, a gas furnace is able to heat the home to a comfortable temperature faster when compared to electric systems. Snell Heating & Air Conditioning provides reputable electric furnace repair and installation services in Centreville, Virginia.

Central Air Conditioning Installation & Repair Services

The average high temperature in July for Centreville, Virginia is a blistering 87.5 degrees Fahrenheit. This is well above the national average in July, which is only 85.8 degrees fahrenheit. To protect the health of your family and friends during the summer, we recommend investing in a central air conditioning system. If you’re having problems with an existing cooling system, give our team a call by phone at (703) 543-9649. We offer central air conditioning repair services for small to large homes in Centreville, Virginia.

Air ConditionerHow An Air Conditioner Works

A central air conditioner includes a compressor that is engineered to transform refrigerant from a gas to a liquid. Next, the liquid refrigerant is pushed through a network of refrigerant lines to the evaporator coil in your home. The fan on your interior HVAC system is activated to ensure the incoming warm air is pushed across the fins on the evaporator.

As the warm air is pushed over the evaporator fins, the refrigerant is transformed from a liquid to a gas form. This process is utilized to adjust the temperature of the incoming air from the house. Once the air has reached a predefined temperature, it is pushed through the air ducts and vents in each area of your house Snell Heating & Air Conditioning provides superior air conditioning repair, maintenance, installation, and replacement services to residents in Centreville, Virginia.

Water Heater ServicesHow Gas and Electric Water Heaters Operate

Both gas and electric water heaters turn on when the thermostats detect the water temperature is below the optimal settings. However, the components within each type of water heater run definitely to achieve the same goal. In a gas water heater, a valve will open so gas can flow and ignite at a burner located under the tank. With an electric water heater, heating elements are warmed up through an electric current and then pushed underwater. Both methods continue heating the water tank until the temperature rises back up to the correct settings.

Indoor Air Quality ServicesIndoor Air Quality Services

Did you know the U.S. Environmental Protection Agency determined that the air quality in an average home is 5 times worse than the air outside of it? This is likely due to the structure and insulation that are trapping contaminants in your house such as pollen, dander, and dust mites.

Our staff of technicians can help purify the air and even eradicate certain types of illness-causing bacteria by installing ultraviolet (UV) lamps. To eliminate dry air, our staff will discuss adding a humidifier or dehumidifier to your system while we are performing a furnace repair at your house in Centreville, Virginia during the winter season. All you need to do is meet with our indoor air quality specialists to mitigate your family’s airborne health risks!

Humidifier Installation & Repair Services

The two variables that are responsible for discomfort in homes are temperature and humidity. While investing in an eco-friendly furnace or air conditioner will enhance your comfort, integrating a humidifier is vital to protect your body from the negative consequences of dry air.

Benefits of Installing a Humidifier

Decreased Probability of Catching a Cold or Sickness

The mucus membrane in the respiratory systems of our body is designed to protect us from the common cold and the flu. Since the mucus membrane becomes dry in the winter, this inhibits its ability to protect the body from illnesses. To enhance your health, consider adding a humidifier to your house.

Healthy Skin

A clear benefit of installing a humidifier in a home is healthy and radiating skin. If the air in your house is too dry, this will cause the formation of dry skin, cracked lips, bloody noses, and more. Enhance the health of your skin by calling us at (703)-420-1834.

Enhanced Sleeping Patterns

Since a humidifier is able to lower your chances of getting a cold or the flu, you will feel healthier in a house with this type of system. You will be less likely to develop physical health conditions that may impact your sleep patterns, such as sore throats, headaches, coughing, and stomach aches.

Additional Savings on Heating Bills

Boosting the amount of moisture in the air will help your house feel warmer at lower temperatures. As a result, most homes that include central humidifier systems use the furnace less often. We recommend purchasing a central humidifier to save money on your heating bills.

Protects Furniture From Damage

If the air is too dry in your home, this can cause your wood furniture to crack or warp over time. To protect the furniture in your home, we recommend scheduling a humidifier installation appointment with our team.
