Lennox Furnaces Installation And Replacement

One aspect about heaters most do not realize is that your furnace or air handler actually works Year Round. Whether in summer or winter your furnace or air handler is the only machine that is moving air through the AC system. This means that your heating system is integral to the performance and efficiency of your homes heating and cooling. Better furnaces and air handlers have the ability to make your home more comfortable and more efficient year round.

If you have an older, inefficient furnace or a furnace that needs frequent repairs, it may be time for an upgrade. There are many benefits to upgrading your home’s heating system. The benefits of installing a new furnace:

• Increased safety – As furnaces age, they run the risk of developing cracks in the heat exchanger, so if carbon monoxide is present it could leak into your home undetected
• Cost savings – A new energy efficient furnace can save you up to 25% of your home’s heating costs per year
• Increased efficiency – Older furnaces are typically not very energy efficient. As your furnace ages, it can begin to lose its effectiveness, requiring more service calls and frequent repairs
• Future investment – By upgrading your home comfort systems, you’ll increase the total value of your home
