The price of a new gas furnace can vary significantly. Some models cost up to 100% more than others. High-efficiency models are typically more expensive. Other options include two-stage or variable-speed models, which can offer more comfort and control. The Lennox brand of gas furnaces is an example of a high-efficiency model.

High-efficiency models cost 50% to 100% more than standard models

High-efficiency models are priced higher than standard models, but not necessarily more. According to DOE (2011), retailers mark up high-efficiency models by between 50 and 100%. Other studies indicate that high-efficiency models are priced as premium products. Retailers may also mark up high-efficiency models by between 1.5 and two times.

Variable-speed models offer more control and comfort

Variable-speed gas furnace models give homeowners more control and comfort. They help you adjust the temperature while achieving the highest AFUE rating possible. This means that you can save on energy bills and enjoy consistent comfort in the winter. They are also quiet, deliver consistent airflow, and can help you control the humidity in your home during the summer.

Variable-speed gas furnace models use less electricity than conventional models. The variable-speed motor saves up to 66% of electricity when compared to the conventional blower motor. This translates into hundreds of dollars in energy savings each year. In Western New York, for example, a variable-speed gas furnace will save $398 per year by lowering its heating and cooling speeds. With a variable-speed model, you can also adjust the fan speed by a single-percent increment to meet your comfort needs. Another feature that sets these units apart is their modulating gas valve. They use a multi-stage gas valve to regulate the amount of fuel they burn. This means that they can cut back on output when the room has reached the desired temperature, and eliminate energy spikes that result from turning the heating on and off.

Two-stage models offer more control and comfort

Two-stage gas furnace models have a high and a low setting to regulate the amount of heat produced. This allows the furnace to run at full capacity when needed and at a lower setting during milder days. This can increase efficiency while at the same time providing more even heat distribution throughout the house. Two-stage furnaces also require less energy than single-stage models.

Two-stage gas furnace models offer the best value. They tend to be quieter, more efficient and have more comfort features than single-stage models. Some models have modulating gas valves and variable-speed blower motors. These features enable the furnace to manage the temperature more accurately and produce a more even temperature in every room.

Two-stage furnaces can be quieter, which helps prevent temperature fluctuations. In addition to that, contractors who install these furnaces know how much airflow is necessary to heat the home evenly. Two-stage furnaces typically run at seventy to eighty percent of their rated capacity, which reduces temperature swings and keeps the home warm without requiring extra energy.

Lennox gas furnaces are high-quality, high-efficiency models

Lennox is known for its quality and low-maintenance HVAC equipment. The company has been designing and manufacturing heating and cooling equipment for decades. They have spent nearly a century honing their craft to provide high efficiency, smooth operation, and maximum comfort. Their furnaces come in a variety of designs and energy-efficiency ratings. There are single-stage, oil-fired, and combination models.

Lennox furnaces are more expensive than their competitors, but they’re also better built and quieter. The company also spends a lot of money on marketing and advertising to ensure that its furnaces will have a prestigious reputation. Their furnaces are among the most efficient on the market, and they can last anywhere from 15 to 20 years.

Both Lennox and Trane are well-established companies that have been manufacturing furnaces for years. Their products have excellent reliability metrics and very few problems during the warranty period. However, there are some routine maintenance needs to keep the furnace running properly and efficiently.
