If we were to ask you the relation between your HVAC systems and your home’s indoor air quality, what would you say?
If you’re like many homeowners, you would say that your indoor air quality is determined by the temperature of your home, which of course is controlled by your HVAC systems. This isn’t wrong, but it’s not completely right either. Temperature is only part of good indoor air quality.
Another relation between IAQ and HVAC systems that people make is that their HVAC systems’ air filter protects their indoor air quality. This is also not quite true. It certainly helps with indoor air quality, but this air filter is in place to protect the HVAC systems themselves.
