Gas Furnaces

You should have your gas furnace serviced at least once a year, ideally before the heating season begins. Regular maintenance helps ensure that your furnace operates safely and efficiently, extends its lifespan, and can prevent unexpected breakdowns. It’s also crucial for identifying potential carbon monoxide (CO) leaks, which can be dangerous if not caught early, as CO is an odorless, colorless gas that can cause serious health risks. Evergreen Home Heating and Energy offers comprehensive maintenance plans to keep your furnace in top shape and ensure the safety of your home.

Common signs that your furnace may need repair or replacement include inconsistent heating, unusual noises, frequent cycling on and off, higher energy bills, or if the furnace is more than 15-20 years old. Our technicians can assess your furnace and help you decide whether a repair is sufficient or if replacement would be more cost-effective.

The average lifespan of a gas furnace is around 15 to 20 years, though this can vary depending on how well the system is maintained. Regular servicing and timely repairs can help extend the life of your furnace. If your furnace is approaching this age and experiencing issues, it may be time to consider a replacement.

Modern gas furnaces are highly energy efficient, especially high-efficiency models with an Annual Fuel Utilization Efficiency (AFUE) rating of 90% or higher. This means that 90% or more of the fuel consumed is converted into heat for your home, reducing energy waste and lowering your heating bills. Evergreen Home Heating and Energy can help you choose a furnace with the right efficiency rating for your home.

The size of the gas furnace you need depends on factors like the square footage, insulation, and layout of your home. An undersized furnace will struggle to heat your home adequately, while an oversized furnace can lead to inefficient operation and higher energy bills. Our team at Evergreen Home Heating and Energy can perform a detailed load calculation to ensure your furnace is correctly sized for optimal comfort and efficiency.

A variable-speed furnace adjusts the speed of the blower motor to match your home’s heating needs more precisely. Unlike traditional single-speed furnaces that only operate at full blast, a variable-speed furnace can run at lower speeds for longer periods, offering better temperature control, increased energy efficiency, and quieter operation. This feature can also improve indoor air quality by circulating air continuously, even when the furnace isn’t actively heating. We can help you explore variable-speed options to enhance your home’s comfort and efficiency.

A two-stage furnace operates at two different levels of heat output: a lower stage for milder days and a higher stage for colder days. This allows the furnace to run more efficiently, providing consistent comfort while reducing energy consumption. The lower stage runs longer and more evenly, minimizing temperature fluctuations in your home. At Evergreen Home Heating and Energy, we offer two-stage furnaces that provide better comfort and energy savings compared to single-stage models.

A modulating furnace continuously adjusts its heating output in small increments to match your home’s exact heating needs. Unlike single-stage or two-stage furnaces, which operate at set capacities, a modulating furnace can vary its output to maintain a consistent temperature, minimizing temperature swings. This precise control not only improves comfort but also increases energy efficiency by reducing fuel consumption and preventing the system from running at full capacity when it's not necessary. Modulating furnaces also tend to operate more quietly and provide better airflow. At Evergreen Home Heating and Energy, we can help you choose the right modulating furnace to optimize comfort and efficiency in your home.
