Not all a/c units are created equal. Some people are under the impression that an air conditioner is an air conditioner, and a furnace is a furnace, and an air purifier is an air purifier, but after doing even a little bit of research, one can find that HAC units are very different and for different uses. Let’s begin this discussion with air purifiers. A normal air purifier is great for a small room, but if your want special air purification, you may want to stick with a HEPA air purifier. If you want a more modern and slick looking air purifier, you may want to choose a UV light air purifier instead. There are electronic air purifiers, central air cleaners, HEPA air purifiers and so much more! The options are endless when it comes to air purifiers. Air conditioners are a bit more complicated. If you do not have the right air conditioner suited for your specific needs, you may end up not being cool enough or your thermostat may read too cool. If you have a small area you would like to be cool, try getting a medium sized window air conditioner for it. If you are looking to have your entire home the same temperature, try a central air conditioner, or a zone control central air conditioner. And lastly, if you want two different rooms to be the same temperature, go for a multi split air conditioner to make it happen! And always remember to put an air filter in all your air conditioners because this will help keep the air clean and the air ventilation system clean as well.
