A Carrier PTAC can save you 15 to 20 percent per year on your heating and electricity bills. Highlights of the Carrier PTAC include two-stage condensate removal, a high tech grill, energy-saving switches, and an incredible ARI efficiency standard. The through the wall chassis of this top-of-the-line Carrier PTAC is easy to install and a snap to clean.

That being said, any time you put in a PTAC, you're probably going to have to drill a hole in your wall. Carrier PTACs are 42 inches in width--standard for the industry. If you don't want a 42-inch hole in your wall, you might want to opt for a through the window model. Of course, regardless of whether you go through the wall or the window, you should make sure that your exhaust and ventilation systems are functioning smoothly.

Moreover, just because the Carrier PTAC offers state-of-the-art filtration control doesn't mean that you can be lazy in terms of replacing your filters. When condensate material and debris fill up your filter, the unit can expel this material into your living space. These particles can contribute to indoor air pollution, which has been shown to increase the risk of emphysema, lung cancer, and fatigue.

The good news is that Carrier PTACs come with exceptionally meticulous maintenance and service plans. Moreover, these units tend to last longer than other major models on the market. Thus, if you're investing for long-term air quality control--particularly for a hotel or industrial business--a Carrier PTAC is a good bet.
