    Why Does the Size of My HVAC System Matter?

    Wednesday, November 02, 2016


    If you’re wondering why the size of your heating and air conditioning system matters, we’re here to tell you.

    It might seem like when you need to heat or cool your home, any heating and air conditioning system will do. They all provide the same service, right? Well, yes and no. While all systems are designed to do basically the same thing, they need to be matched to the size of the space they’re cooling, or else they are inefficient and ineffective. Let’s take a closer look.

    Too Small: HVAC Hardship

    If an HVAC system is too small, it will not be able to handle the load placed on it by the space it’s meant to heat or cool. When it can’t meet the need of that space, it works overtime but still can’t adequately heat or cool the space. You may need to add additional units (like space heaters or window air conditioners) to try to make up for it, which is expensive and inefficient.

    Too Large: HVAC Humidity (Yuck!)

    HVAC systems that are too large are inefficient in a different way. They work too well, meaning they hit their target temperature in a very short period of time, after which they turn off. This is called short cycling, where the unit turns on and off very rapidly. Unfortunately, these short, frequent cycles are not long enough to run the air in the house through the filter, which is what removes humidity. Your home will likely be hot or cool, but sticky.

    Just Right: HVAC Heaven

    When your HVAC system is the right size, you’ll experience a number of benefits:

    • Space you’re trying to heat or cool will routinely hit optimum temperatures.
    • The air will be comfortable and dry
    • Your energy bills won’t suffer the spikes caused by the constant on-off of short cycling.
