If your air conditioner is not working during the summer season, then you’ll probably notice the problem right away. Same with your heater in the summer. A heater blowing cool air is obviously going to lead to problems in your home and with your comfort. What about your indoor air quality, though? Is it as high as it should be? Do you do anything to keep it at a high level? Have you even really considered it much?
If not, then now is the time. It sounds surprising, but the fact is that the air quality in your home may well be lower than the air quality outside! This makes sense. Sure, there is air pollution outside. However, the air outside is not trapped indoors, being recirculated through your HVAC system over and over. While opening up your windows on nice days will help to refresh the air in your home, it typically won’t have a huge effect on boosting air quality.
