![]() ![]() ![]() They also provide a higher level of comfort due to a steady flow of warm air on the coldest winter days.įYI: "Variable Speed" refers to the blower motor - how much air it moves through the ductwork. Two-stage furnaces also help to increase energy efficiency on moderate-temperature days since they will, in most cases, remain on the low stage. This allows warm air to be distributed into your home more evenly, which helps to reduce air fluctuations. When the temperature outside becomes extremely cold and the first stage is not sufficient enough to heat your home, the second stage kicks on to provide the additional heat requirements. #Quiet 3 stage boiler fullMany are available with two-speed compressors and variable-speed air handlers for the ultimate in comfort and efficiency.įor most climates, the first stage operates the majority of the time, and runs at about 65% of the furnace's full capacity. If you are in the market for a new gas furnace, then without a doubt, a variable-speed, two-stage furnace would be your best choice! And the same applies to heat pumps. In addition, a two-stage furnace is much quieter since it doesn't operate at 100% capacity every time it runs, and creates less carbon dioxide emissions for the environment. It provides the right amount of heat to efficiently satisfy your home and family's needs. When the fan is in constant operation (indicated by the "Fan" setting on your thermostat), the motor will continue to slowly circulate air, allowing your air filters to capture more contaminants.Ī two-stage furnace operates much more efficiently than a single-stage furnace. A variable speed motor can also help better clean the air in your home.The furnace slowly ramps up to speed, so there’s no sudden "kick" or "blast" of air at startup. A variable speed furnace or air handler also ensures quieter operation.All of this, over the course of just one year, can add up to hundreds of dollars off your electric bill! The higher the SEER, the lower your utility bills. During the cooling mode, variable speed systems typically result in an efficiency gain of about 1 SEER (Seasonal Energy Efficiency Ratio). Compared to a conventional single-speed furnace, a variable speed furnace performs better and uses about two-thirds less electricity.A higher degree of precision means a higher level of comfort. A variable speed heating system precisely controls airflow to provide better temperature control, humidity control and air distribution.And in the cooling mode, it allows the air conditioner to remove more moisture from the air. It also reduces stress on the mounting hardware. Noisy blast of air that’s associated with standard furnace motors. ![]() Put simply, it delivers just the right amount of air for the right level of heating and cooling comfort.Īs an added bonus, a variable speed motor gradually ramps up to full speed. It varies the amount of circulated air, compensating for factors like dirty filters or blocked vents by increasing the fan speed. Using advanced technology, it constantly monitors the data coming from your heating and cooling system, and automatically makes adjustments necessary to meet your comfort needs. Better airflow control means a better balance of temperature and humidity. Unlike conventional fan motors, a variable speed blower motor runs at different speeds to precisely control the flow of heated or cooled air throughout your home. ![]() The initial cost of a furnace with an ECM will be higher than a traditional furnace, but the typical payback on a variable speed furnace is just 4 to 5 years. ECM's are DC motors that function using a built-in inverter and a magnet rotor, and as a result are able to achieve greater efficiency than most AC motors.ĮCMs are low-maintenance, energy efficient, and can reduce operating costs. It's an Electronically commutated motor, or (ECM). The term "Variable Speed" actually refers to the blower motor inside the furnace or air handler. ![]()
