Furnace Repair & Install Services

Electric and gas furnaces each come with advantages and disadvantages. Electric furnaces are typically quieter, quicker to install, and easier to maintain in comparison to gas furnaces. Though electric furnaces are cheaper to install, they are typically more expensive to operate each month. However, electric furnaces tend to be more durable and have an average lifespan of 20-30 years.

Gas furnaces, on the other hand, are more expensive to install but tend to be cheaper to operate each month. If you need help comparing the benefits of gas and electric heating systems, give our team a call and schedule an appointment. We offer heating repair and installation services in areas such as Centreville, Arlington, Ashburn, and Reston. If you choose to invest in a gas furnace, you will also need to have a carbon monoxide detector installed in your home to protect your family from gas leaks. Gas furnaces have a shorter lifespan, with an average of 15-20 years.

4 Types Of Furnace Noises & How To Fix

Banging Noises

Once the gas burners in your furnace become contaminated with dirt and dust, it will take longer to ignite incoming gas. This type of problem will cause gas to collect in the system and explode when the electric igniter or pilot light is activated. To prevent damage to the heat exchanger in your furnace, immediately call a licensed technician to perform a heating or air conditioning repair service in Arlington and other areas of Virginia.

If your furnace produces a banging noise when it is turned on, immediately call a licensed technician to perform a heating repair. Our team of certified contractors will perform an inspection and sanitize your gas burners to eliminate the build-up of gas in your furnace. Give our team a call by phone at (703) 543-9649 to receive help with your broken furnace.

Grinding Sounds

It is not normal for a furnace to produce a grinding noise while it is operating during the winter. If you notice a loud scraping noise when your furnace is activated, this is a sign of a loose blower fan. When the fan becomes insecure, it will start to hit the blower motor. To prevent damage to the fan, it’s important to fix this problem as soon as possible. Once you schedule a heating repair, a licensed professional will replace the part that is designed to connect the fan to the blower motor.

Squealing Noises

When a furnace starts to create a squealing sound, you will need to remove the access panel to investigate the blower motor. If you have a motor that is integrated with a belt, the source of the shrieking noise may be a disconnected belt. In addition, a squealing sound can indicate a high amount of friction in your furnace. We offer trustworthy heating repair services to households in Alexandria and other areas of Virginia. Our licensed technicians will lubricate the shaft bearings and other parts in your furnace to eliminate the howling noise.

Knocking Sounds

A knocking noise coming from the furnace is a sign of a hole in your heat exchanger. Once a heat exchanger is damaged, carbon monoxide may start to leak into the air in your house. To prevent gas poisoning, it’s critical to call our team of licensed technicians by phone at (703) 543-9649 to perform a heating repair. We have the tools necessary to replace the damaged heat exchanger and perform heating services in your home. On the other hand, the source of the knocking noise may be a loose bolt or screw.

Grab a screwdriver and tighten the screws to secure the access panel to the furnace. Once the screws are tight, activate your furnace to confirm if the knocking noise has been eliminated. If your furnace continues to produce strange noises, this is a sign of a severe problem with the heat exchanger. Call a licensed contractor at our company to receive help with a furnace problem.

4 Causes of Furnace Short Cycling Problems

A standard furnace is engineered to fulfill heating cycles that vary from 10 to 15 minutes depending on the interior temperature of your house. If your furnace is activating and deactivating in 5 minutes or less, this is a sign of a problem. This type of problem is referred to as short cycling in the heating and cooling industry. To help you diagnose the source of the problem, we have compiled a list of ordinary causes of furnace short cycling and troubleshooting methods.

Dirty & Broken Flame Sensors

The flame sensor in a gas furnace is engineered to detect flames. If the sensor does not sense flames, it will close the gas valve and deactivate the furnace to prevent a gas leak in your house. If your furnace is activating and deactivating every couple of minutes, it’s important to hire a professional to perform an inspection of the flame sensor. Our team offers heating repair services and have the tools necessary to fix your flame sensor.

There are two types of problems that can prevent the flame sensor from sensing the flames in your furnace. If the exterior of the flame sensor is covered in dust or dirt, this will prevent it from detecting incoming natural gas and flames. On the other hand, corrosion may negatively impact the performance of the flame sensor.

Closed Supply Vents

If your furnace is turning on and off every 3 to 5 minutes, this is a sign of overheating. Take a walk around your house to confirm if your supply vents are open or closed. An easy way to prevent your furnace from becoming too warm is to open 80% of the vents in each room of your home. If a majority of your vents are closed, heat will become trapped in the interior of your furnace. In addition, the heat that is exiting your open vents will be extremely hot.


If you are having trouble determining why your furnace is overheating, give our team of technicians a call by phone at (703) 543-9649 to schedule a time for a heating and air conditioning repair service in Arlington and other areas of Virginia. Prior to calling a certified professional, it’s important to check each supply vent in your home to confirm if it’s open. In addition, inspect the location of your furniture to confirm it’s not blocking the distribution of warm air from your vents.

Dirty Air Filter

An air filter is designed to extract dirt, dust, and debris from the air before it is circulated to your gas or electric furnace. To ensure the air entering your furnace is clean, it’s important to replace your air filter when it becomes contaminated. Once the air filter is covered in dirt, it will become harder for incoming cold air to enter your furnace. This type of problem will cause your furnace to overheat and shut down. If your furnace is activating and deactivating every 3 minutes, you will need to replace your dirty air filter to ensure cold air is distributed to your furnace.

Thermostat is Installed in a Bad Location

The thermostat should be installed away from windows and supply vents in your house. If you choose to configure your thermostat above a vent, it will detect the warm air exiting the air duct and deactivate the furnace. If your furnace is turning on and off at a rapid rate, give our team of licensed contractors a call by phone at (703) 543-9649 to create a heating and air conditioning appointment. When we arrive at your home, we will inspect the location of your thermostat to confirm if it’s in a central location.

If your thermostat is installed in a supply closet, we will remove it to eliminate the furnace short cycling problem. If your thermostat is installed in a supply closet, its sensor will detect the warm air that is trapped in the closet. This will cause the thermostat to reach its set temperature point before other parts of your house are warm. To prevent heating repair problems, it’s best to install your thermostat in a central location such as a hallway, family room, or dining area.

Indoor Air Quality Services

Ways to Improve the Air Quality in Your House

Since the early 1970s, most new homes have implemented a more energy-efficient design in their construction. Homes were built “tighter” using additional insulation, double glass windows/doors, and more weather stripping. This “tighter” method of construction is more resistant to fresh air exchanges and therefore tends to trap stale, stagnant, and polluted air. If you want to improve the quality of air in your home, give our team a call at (703) 543-9649 to book a heating and air conditioning repair service.

Electronic Air Cleaners

These electronic devices filter out large particles and contaminants from the air indoors. Electronically charged devices trap tiny particles including viruses and bacteria in the collector plate. These plates help remove small breathable particles and other bioaerosols. The team at our heating company near you provides dependable electronic air cleaner installation or replacement services.

Electrostatic Air Filters

We offer electrostatic air filter installation and replacement services to homes in Alexandria and other locations in Virginia. An electrostatic air filter utilizes static electricity to extract contaminants as they are circulated through the filter media. Although a majority of electrostatic air filters are washable, there are a large number of pleated filters that are electrostatic.

This type of filter is engineered to remove pollen, dust, and dirt particles from the air. As the incoming contaminated air enters the filter, the ionizers release charged ion particles that are designed to attract dirt and dust. In addition, an electrostatic air filter features a carbon barrier that is designed to collect remaining contaminants before the air is distributed to each room in your home. This type of air filter can eliminate about 70% of fine particulate matter such as dust and cigarette smoke from the air. If you want an electrostatic air filter for your home, give our staff a call by phone at (703) 543-9649.

UV Air Disinfection Systems

Our affordable UV air disinfection system helps kill bacteria, viruses, mold, fungi, and other unwanted living things in your home. Particles such as pollen, dust, food, and pet odor can be absorbed with UV light to purify the air as it passes through. This system kills bacteria, odors, and other contaminants.

High-Efficiency or HEPA Filters

We offer HEPA air filter installation and replacement services to homeowners in Centreville, Alexandria, and Arlington. The term HEPA stands for “high-efficiency particulate air.” A HEPA air filter is assembled with fibers or synthetic materials that are designed to remove extremely small contaminants from the air in your house. This type of air filter can extract bacteria, pollen, viruses, mold, allergens, and PM2.5 before they are distributed in your air ducts. I

In addition, HEPA filters are utilized to capture nanoparticles. HEPA air filters are engineered to remove 99.97% of particles to ensure your air is clean. If you suffer from allergies or other medical conditions, give our team a call by phone at (703) 543-9649 to become familiar with our heating and air conditioning repair services. You may benefit from the installation of a HEPA air filter that is designed to extract pollen and mold.

Whole House Humidifier Installation

On average, most of us spend around 90% of our lives indoors. Since poor indoor air quality can negatively impact you and your family, you should take the proper measures to improve the indoor air quality in your home. Improper humidity levels in your home can result in dry skin, colder homes, damage to property, and even can make it easier for viruses to spread. Luckily, these problems can be easily prevented with a whole-house humidifier. Our professional technicians offer fast heating and air conditioning services for whole-house humidifiers to homes in areas of Virginia such as Reston, Arlington, Centreville, and Alexandria.

A whole-house humidifier is installed in your ductwork near your furnace, either on the supply or the return end. The humidifying unit is connected directly to your home’s water supply. Inside your whole-house humidifier, you will find either a humidifier pad, a rotating drum, or a steaming system that is used to evenly distribute water into the air in your home. Air from your ducts enters the humidifier and is exposed to water inside. Water evaporates into the air, increasing the moisture levels of the air that exits the humidifier on the other side. Our team of contractors provides exceptional heating repair and humidifier installation services to homes in Northern Virginia. Our staff will help you choose a whole-house humidifier system that is compatible with your living space.
