There are a lot of options to consider when choosing a new HVAC system. What’s the manufacturer’s reputation? What’s their warranty like? Does the system offer the features you want, such as a variable speed motor? What’s the rated efficiency? One of the most important features you need to consider is the size of your system. An HVAC installation that’s oversized or undersized won’t keep your home comfortable.
A system’s size depends on many factors, including the amount of windows in your home, the size of your home and your temperature preferences. When a system is sized correctly, it will deliver the set temperature to keep you comfortable and maintain that temperature. An undersized system won’t be able to get your home to the correct temperature, while an oversized system will overshoot and shut off, leading to dramatic temperature swings.
Why Size Matters
But there are other reasons that bigger isn’t necessarily better when it comes to your HVAC system. An oversized system draws more power, costing you more money. Larger systems also cost more upfront, not to mention the increased wear and tear on internal components from continuous on-and-off cycling. Worse, because it’s not running as steadily as a properly-sized installation, you don’t get the auxiliary benefits of a central air system. Less air filtration happens because it’s not circulating air as much, and you don’t get the same humidity control through the summer months.
Because your home’s ability to hold on to a comfortable temperature influences the sizing of your HVAC system, you should make sure that your heating and cooling loads are re-evaluated if you’re upgrading as part of a series of home efficiency improvements. You may end up needing a system that’s sized smaller than the one you’re used to.
