small AC systems

Some HVAC companies and many homeowners seem to think that bigger is always better when it comes to sizing a new system. In fact, a system that is sized too large for a house will run inefficiently, turning on and off (aka short cycling) so that the system never reaches set temperature points.

One of the main reasons homeowners get stuck with a system that’s too big for the house they’re in is that it was sized solely based on square footage. To be more accurate, the consultant should not only go by square footage but also by factors that take into account the orientation of the house, such as the number of windows, the number of occupants, and other factors. This information is fed into industry software called Manual J, which will help the consultant determine the size system that will best work for that dwelling, so you know if picking from a selection of small AC systems is a better option for you.

This is one instance when small AC systems, or smaller HVAC systems, might be a better choice. But there are other scenarios when, if you’re facing replacing an HVAC system, you might want to think smaller. Because we’re in the cooling season, let’s look at different AC solutions.

Ductless Mini Split

Ductless mini splits are not that well known by American homeowners, but their popularity is growing. As the name implies, you don’t need ductwork for this type of heat pump, which consists of an outdoor condenser connected to an indoor air handler by a conduit, which contains the wiring and refrigeration tubing. Like a heat pump, the mini split removes heat from the home and exhausts the hot air outside. These small AC systems are clean, quiet, and efficient.

Portable Air Conditioner

Portable air conditioners have been vastly improved from previous years, running a tad bit quieter than they used to. However, they must be moved around and are still rather noisy and obtrusive.

Window Units

Like portable ACs, window units have been improved, and though they are still rather noisy, they’ve been quieted down and are more efficient than they used to be. They’re also inexpensive, but you must fit them into a window.
