The summer months in Reston, Virginia are filled with hot and humid weather. With an average high temperature of 78 degrees Fahrenheit, it’s important to invest in a high-quality air conditioning system to maintain the comfort and safety of your home. Snell Heating & Air Conditioning offers dependable air conditioning repairinstallation, and tune-up services to homes in Reston, Virginia.

Air Conditioner

How an Air Conditioning System Works

Your central air conditioning system relies on refrigerant or coolant to remove excess heat from the air in your house. An air conditioner is built with 3 components, including the compressor, condenser, and evaporator. While the compressor and condenser are located outside, the evaporator can be found inside your home.

Once the molecules of the refrigerant reach the compressor of the air conditioning system, they will be compressed to ensure the temperature of the coolant is able to reach an optimal high temperature. Next, the pressurized warm refrigerant will be pushed from the compressor to the condenser of the air conditioning system.

Next, the refrigerant is processed by the metal fins that are located in the outdoor air conditioner. These fins are engineered to deplete the excess heat from the coolant before it reaches the evaporator. As the refrigerant is being prepared by the condenser, it transforms from a high-pressure gas to a liquid with a lower temperature.

Once the condenser is finished with the refrigerant, the liquid is pushed to the evaporator of the HVAC system in your house through a thin hole. As the refrigerant is traveling through the evaporator of the air conditioning system, its pressure will begin to decrease. As a result of the substantial pressure changes, the coolant will be reconstructed as a gas.

While the refrigerant is being converted to a gas, a supply of heat energy is released to divide the liquid molecules into a gaseous state. The fan that is integrated with the evaporator will push this cold gas throughout your home to maintain or lower its temperature.

While the air conditioning system may utilize a simple method to remove heat from your home, there are many components and parts that may begin to malfunction as your system becomes older. Snell Heating & Air Conditioning provides reputable and trustworthy air conditioning repair services to homes in Reston, Virginia. Give us a call by phone at (703) 543-9649 or book an appointment online to receive assistance.


5 Common Air Conditioner Repair Issues

Ice on Evaporator Coils

To operate properly, the evaporator coils of an air conditioning system rely on surrounding hot air to prevent issues. These coils are filled with refrigerant and are engineered to eliminate heat from air in the HVAC system. If there is a lack of warm air around the evaporator coils, they will become too cold and freeze. If you notice warm air blowing out of the vents in your home, give us a call by phone at (703) 337-3989 to schedule an air conditioning service appointment.

Clogged Drainage Lines

A common air conditioning repair issue that we encounter a lot during the summer months is clogged air conditioning drainage pipes. These lines are usually located near the air conditioner outside. They are engineered to drain excess moisture from the air conditioning system while it’s operating.

Common signs of clogged air conditioner drainage lines include overflowing condensate pans, standing water, and mold growth. Snell Heating & Air Conditioning provides dependable air conditioning repair, tune-up, and maintenance services to homeowners in Reston Virginia. Give us a call by phone at (703) 337-3989 to receive help.

Malfunctioning Compressor

The compressor in your air conditioner is designed to squeeze the refrigerant to increase its temperature and pressure. A common indicator of an air conditioning repair issue includes the circulation of warm air in your house. Additionally, it’s important to have enough refrigerant in your air conditioner to prevent the compressor from overheating and malfunctioning. Contact a professional to receive assistance with a malfunctioning compressor, refrigerant issue, or other air conditioning repair problems.

Refrigerant Leaks

As a central air conditioning system begins to reach the middle or end of its lifespan, it’s not uncommon for a refrigerant leak to form in varying areas of your system. If there isn’t enough refrigerant in your system, you may begin to notice the circulation of warm air in your house. Consult with a licensed air conditioning repair service in your area to pinpoint the location of the leak.

Faulty Fans

The outdoor air conditioning system features a fan that is engineered to push air from your home over the evaporator coils to decrease its temperature. Additionally, there is another fan inside your system that pushes air to the condenser to ensure excess heat is pushed to the outdoors. If you have a broken fan, contact an emergency technician or plumber on our team to receive fast and affordable air conditioning repair services in Reston, Virginia.

Furnace Installation & Repair Services in Reston, VA

The winter season in Reston, Virginia usually extends from the end of November to the beginning of March. The average high temperature in the area is usually 50 degrees Fahrenheit or less during this time of the year. To ensure you’re comfortable and prevent medical issues such as the flu or common cold, it’s vital to hire a professional furnace service in Reston, Virginia to perform a furnace repair or installation.

Furnace Repair

4 Common Furnace Repair Issues

A standard gas furnace is connected to a programmable thermostat that is designed to provide instructions to the HVAC system. Once the furnace receives instructions to begin the heating process, a gas valve is opened to ensure gas is able to be pushed to the burners. Depending on the age of your gas furnace, a standing pilot light or electronic ignition system will be utilized to ignite the gas from the burners.

Warm air is created within the heat exchanger prior to being sent to the plenum and air ducts in your house. Since the furnace utilizes an intricate process to produce heat, it is not uncommon for problems to occur that can only be resolved by a certified furnace service in Reston, Virginia. These are the most common furnace issues we’ve discovered in homes:

Broken Heat Exchanger

Cracks may begin to form in the heat exchanger of your furnace as it becomes older. These cracks may cause a moderate to severe carbon monoxide leak to form in your home. If these leaks are left undetected for too long, they may cause medical issues or fatalities. To protect your family or spouse from a gas leak, book a tune-up appointment with a licensed furnace service in Reston, Virginia.

Deactivated Safety Switch

The safety switch on a gas furnace is engineered to deactivate the fan and gas burners while the system is being serviced. In order for the furnace to operate properly, the door of the system must be closed. If your furnace door is attached and your unit is not activating, call our team of technicians to learn more about our furnaces services in Reston, Virginia.

Clogged Air Filter

If your furnace is not producing a sufficient amount of warm air, this may be caused by a clogged air filter. When a filter is clogged, it becomes harder for the gas furnace to push air through the filter and air ducts of the home. To increase the efficiency of your furnace and enhance the comfort of your home, replace the air filter continuously throughout the year. If you need assistance replacing an air filter, Snell Heating & Air Conditioning provides emergency furnace services in Reston, VA.

Contaminated Burners

Most types of furnace issues originate from filthy gas burners. So, how do you determine if your burners are contaminated? Simply activate your furnace and analyze the color of the flames. If the flames from your gas burners are blue, this is a sign of a clean and well-kept furnace. However, the production of yellow flames may indicate an excessive amount of dirt and debris in your burners. Since the process of sanitizing gas burners can be dangerous, we recommend hiring a furnace service technician from Snell Heating & Air Conditioning.

Need a New Furnace? Become Familiar With British Thermal Units

Prior to choosing a new furnace for your home, you should become familiar with the metric British Thermal Units (BTU’s) to ensure you don’t purchase an incorrect system. A BTU is a key performance indicator that it utilized to measure the efficiency of a gas furnace. A single BTU portrays the total amount of energy required to boost a pound of water by one degree Fahrenheit.

Plumbers, HVAC, & Air Conditioning Repair in Reston, VA

To accurately determine the proper BTU rating for your new furnace, you will be required to calculate the total square footage of your home. To do this, you will be required to measure the width and length of each room of the enclosure. To obtain the square footage for a single room, multiple the length and wide together. Next, repeat this process for each room in your home to obtain the square footage of each room. Lastly, add the individual square footages of each room together to receive the total square footage of your entire house.

Small homes that include 1,200 square feet of space will require a furnace that is between 35.000 to 75,000 BTUs. On the other hand, large houses that feature 2,400 square feet of space will be required to select a furnace with 75,000 to 145,000 BTUs. Snell Heating & Air Conditioning provides furnace installation services to residents in Reston, Virginia.

Water Heater Services

How Gas and Electric Water Heaters Operate

The way water heaters start warming up the water in their tanks is through their thermostats. The thermostat signals to the inner components that the internal water temperature is too low. Next, a gas water heater opens up a valve to release gas to the gas burner. This combusts and heats the bottom of the tank until the water is hot enough. On the other hand, an electric water heater ignites a heating element and inserts it into the water as its heating method. Either way, both processes stop once the water reaches the right temperature. Our staff of emergency plumbers offer water heater repair services to homeowners in Reston, Virginia. We have the tools and equipment necessary to fix your broken heating elements or gas burner.
