Furnace RepairGas Furnace Advantages

Efficiency

Gas furnaces are extremely efficient in cold areas of the country. The efficiency of a furnace is measured with a metric called Annual Fuel Utilization Efficiency (AFUE). An AFUE rating can be calculated by analyzing the ratio of the total amount of heat energy produced in a single year by a furnace in comparison to the amount of natural gas consumed. Depending on the type of gas furnace you purchase, the AFUE rating will range from 80% to 98%.

Condensing furnaces are the most efficient type of gas furnace for sale on the market. The AFUE rating of a condensing furnace will vary from 90% to 98%. On the other hand, a conventional gas furnace features an AFUE ratio that deviates from 80% to 85%. An advantage of purchasing a gas furnace includes its high efficiency ratings. If you need assistance with a broken furnace, give our team a call by phone at (302) 367-7915 to schedule an appointment. We offer heating and air conditioning repair services in areas such as Upper Darby, Elkton, Newark, Abington, Ardmore, and Easton. We will help you choose a new conventional or condensing gas furnace for your house.

Warm Air Production

Electric furnaces are more efficient than conventional gas furnaces. On the other hand, a gas furnace creates heat at a faster rate. Gas furnaces produce air that is an average of 20 degrees warmer. Gas furnaces are engineered to create heat energy that ranges in temperature from 110 to 120 degrees Fahrenheit. A large number of homeowners choose to purchase a gas furnace because this type of furnace is designed to heat homes more efficiently when compared to electric furnaces.

Reliability

Electric furnaces rely on a network of power lines that are installed above the ground. Although electricity is a reliable source of energy, it is not uncommon for wind and severe storms to cause damage to power cables. If there is a power outage in your area, the electric furnace will be unable to provide warm air to your household. A benefit to purchasing a gas furnace is reliability.

Since gas pipes are buried beneath the ground, it is rare for an interruption to occur. In addition, a conventional or condensing gas furnace is able to provide warm air to your house during a power outage. If you’re looking to switch from an electric boiler to a gas furnace, give our team of certified technicians a call by phone at (302) 367-7915. We offer heating repair services to homes in Maryland, Pennsylvania, and Delaware. Our contractors have the tools and equipment necessary to install the gas lines and exhaust pipes for your new gas furnace.

Heating RepairEnvironmentally Friendly

The process of creating and distributing electricity has negative consequences on the environment. It takes more energy to produce electricity when compared to natural gas each year. 70% of energy that is utilized to create electricity is lost before it reaches your house.

30% of the energy gets delivered from the electrical suppliers to homes across the nation. This is because energy is lost throughout the distribution process. On the other hand, 90% of natural gas distributed by a gas supplier will reach your property. Only a small amount of gas is lost due to cracks and holes in pipes beneath the ground.

Low Cost

The average price of gas is substantially lower than the cost of electricity. Purchasing a new high-efficiency gas furnace is an excellent way to decrease the total cost of your utility bills each month. In addition, investing in an energy-efficient condensing gas furnace can make you eligible for rebates from your utility provider.

Electric Furnace Repair ServicesAdvantages of Electric Furnaces

Ease of Installation

An electric furnace can be installed relatively quickly by connecting it to your circuit breaker panel. However, the installation process for a gas furnace consists of installing gas lines and exhaust pipes behind your walls. In addition, the heat exchanger and gas burners need to be secured to prevent a gas leak in your household. The exhaust pipe is designed to distribute carbon monoxide from the furnace to the outdoors.

If you don’t have a vent in your house, a hole will need to be cut in your wall for the distribution of natural gas to the outside air. To get help installing an electric furnace, call our certified heating contractors by phone at (302) 367-7915. We offer fast and dependable heating and cooling repair services to homes in areas such as Drexel Hill, Newark, Elkton, Upper Darby, Denton, and Ardmore. Our team will install the high-voltage wires required to operate an electric furnace.

Safety

Gas furnaces feature a heat exchanger, burners, and flame sensor that need to be inspected each year to prevent gas leaks. The interior of an electric furnace includes parts such as a sequencer, elements, fan relay, transformer, and thermal disc limit. The parts in an electric furnace require minimal maintenance. This will help you save money on maintenance and repair fees.

Life Cycle

The average life cycle of a gas furnace varies from 10 to 20 years depending on how often maintenance is performed. A large number of homeowners decide to purchase an electric furnace instead of a gas system because of its long lifespan. Electric furnaces are engineered with a life cycle that ranges from 20 to 30 years. The total lifespan will vary depending on the brand and model you purchase.

Noise

Electric furnaces produce less noise during a heating cycle when compared to gas furnaces. This type of furnace is less loud because it does not have a heat exchanger, gas burners, or exhaust pipes. It’s important to note that gas furnaces produce the most noise when they are activated due to the ignition of the gas burners. This noise will slowly start to fade as the furnace operates.

Heat Pump Repair Services

Our staff of certified technicians offer heating and cooling repair services for heat pumps. Each member on our team is trained to fix broken reversing valves, damaged refrigerant lines, and inefficient starter capacitors. Give our team a call by phone at (302) 367-7915 to create an appointment. We are dedicated to restoring the flow of warm air to your household.

Heating RepairOrdinary Heat Pump Problems

Malfunctioning Reversing Valve

The reversing valve in a heat pump is engineered to adjust the direction of the refrigerant. This allows the heat pump to provide cold air to your household in the summer and warm air in the winter. If your heat pump is not able to produce warm air, this is a sign of a damaged or broken reversing valve. Give our trained technicians a call by phone at (302) 367-7915 to book an appointment. We offer efficient heating repair services to individuals in areas such as Wayne, Easton, Dover, Upper Darby, Ardmore, and Wilmington. Our staff will perform an inspection of the reversing valve and determine whether it needs to be repaired or replaced.

Inefficient Starter Capacitor

Every heat pump is equipped with a component called a starter capacitor. A capacitor is designed to distribute electricity to the motors to activate the heat pump. An ordinary sign of an inefficient or damaged starter capacitor is a tapping noise. The heat pump will produce a knocking noise and will fail to operate.

Low Amount of Refrigerant

If your heat pump is circulating warm air in your house during the winter season, this is a sign of a refrigerant leak. The refrigerant in a heat pump is engineered to extract heat energy from the air in your house. Once the amount of refrigerant becomes too low, the system will not be able to eliminate heat energy from the air.

Dirt & Debris

Heat pumps extract heat from the outdoor air and disperse it into your home. To keep your unit operating properly, it’s important to remove items from the heat pump that are restricting airflow. Remove dirt, leaves, snow, and ice from the system to keep your house warm during the winter season.

The source of strange odors near your boiler may include overheating elements, gas leaks, or damaged circuits. If you notice a whistling sound, this is an indicator of a build up of minerals on the heat exchanger of the boiler. On the other hand, a water leak can be caused by loose water connections or a crack in the water tank.
