Do You Need to Use More Than One Furnace in a Larger Home?

A lot of the time, people believe that installing more than one furnace might be best when they own a large house. However, as many Denver HVAC experts will tell you, that’s not necessarily true, and sometimes an unbalanced system using two or more furnaces can actually waste more energy than you can even imagine.


A common choice among business owners is to put together two furnaces to heat a large hall or office, when a standard size furnace can’t provide the adequate output. While this can work sometimes in the case of large commercial spaces, it doesn’t work so well in a residential home. The main reason behind this is that the twin furnaces will create a higher output than you’d need even on a mild fall afternoon, while wasting too much energy running overtime during cold winter days.


In most cases, the best solution is to hire an HVAC contractor to measure your home and establish a better configuration of using a single, central furnace with the right ducts and the appropriate layout. Adding a good thermostat to the mix will also improve on the situation, and you’ll soon find that you can adjust the temperature in your home perfectly without having to spend a lot of money on a double furnace system.

A HVAC system requires an adequate number of air vents to be efficient. The number of vents generally depends on the square footage of each room; typically a room larger than 100 sq. ft.  requires an additional vent. However, an air conditioning technician is the only one able to make the right estimates.

It is particularly important to talk about this aspect before installing the system. Installing additional vents is expensive and you must know what to expect. The technician will use tape measure, a calculator, as well as a pencil and paper and estimate accurately the required air exchange per hour, for each room. For this, they will do a cubic footage of the room and divide it by four, then make the calculations for the equivalent duct size.

The position of the air vents also matters; they can be in the ceiling, floor or walls. Consider placing them high because vents cut in the floor have drawbacks and are actually specific mostly to old homes, Furniture, as well as toys and other things may block  floor vents. Besides, moisture can find its way in very easily, resulting mold and air restrictions.
