Do I Need a Bigger Furnace?

Before you invest in a new furnace, you need to consider how large of a furnace you need for the size of your home or business. Furnace installation of a new unit has to be sized correctly for several reasons.  Other HVAC contractors offer free estimates on their systems, but with Douglas Cooling & Heating, we want go the extra mile to ensure a properly sized new furnace. We go the extra mile by coming to your home and performing load measurements to make sure you get the correctly-sized furnace you deserve!

Benefits of Proper Sizing

Furnace installation on a correctly sized system offers several benefits. You will experience consistent operation during the coldest days of the year. The furnace will work quietly without you even knowing it’s running. Controlled and even temperatures are achieved easily with a correctly sized furnace. You will save money annually on your energy bill and repairs when you have a furnace installed that meets the size and demands of your home. A furnace that fits the needs and space of your home or office will last longer, too. A furnace’s life expectancy is between 15 to 20 years, but a properly sized unit that is maintained twice a year may offer a longer life.

How to Know Your Unit is Sized Correctly

  • Sound: A correctly sized unit will be almost silent when running. If you hear air moving throughout the ductwork or hear the system constantly kicking on and off, the system probably hasn’t been installed correctly or is sized wrong. At the time of your consultation with a professional at Douglas Cooling & Heating, we take into account your existing ductwork. If your ductwork is too small for the new furnace, the air pushed through the ducts is highly pressured, resulting in loud noises. Small ducts can’t adequately move heated air to all the areas of your home or business.  A professional will know if the unit is sized properly by the sounds the furnace makes during operation.
  • Cold spots: A furnace installed to fit the needs of your home or business will provide exceptional heat to every area, without leaving random cold spots in its wake. If you install a furnace that is too small for the space, it won’t be able to keep up with the demands of your home or business. You will experience areas where the heat is too low compared to other areas. Investing in a programmable thermostat will help you track the temperature in your home, especially with a zoned system. But with a furnace that is too small, it will constantly run to achieve the ideal temperature in your home or office. Keep in mind, a furnace continually running also breaks down more often, and you will pay more for repairs over time.
  • Less efficiency: Whether the unit is too big or too small, both cost you more energy in the long run. Furnaces that are too small and operate constantly use more energy to heat your home. An oversized furnace can heat your home rapidly, but it cycles on and off repeatedly. Continuous cycling causes your furnace to expend more energy than it needs to keep every room warm. The more energy spent to hear your home increases your monthly energy bill. An improperly sized gas furnace can raise your energy bill and also increase your fuel bill every month.
