Just want to be safe with superb air quality

With the restrictions being lifted right now, I truly don’t want to go out, I want to have an HVAC tech come over and take a look at my entire HVAC machine

My village has finally been lifting a pretty good amount of the pandemic restrictions, it seems as though it has been the longest time that I have been stuck inside. I only hang out with my friends and family over Zoom, and generally I must be a hermit for the greater good. Now that my freedoms are trickling back into my life, I want to be very cautious. For so long I wanted to “get back to normal” and now I can easily see that I don’t remember what normal even felt like. I no longer have that powerful desire to go out and mingle with others, I want to stay inside protected by my HVAC machine and its many air filters. Never before in my life have I ever done so much research on air quality, and the things we often breathe in without actually realizing it. I know that my cooling machine doesn’t supply a magic shield against the world, however it at least gives me somewhat of a bubble. Inside this bubble, the air filters recycle the air over and over, so unless new, outside contaminants are taken into my place, things stay easily clean. With the restrictions being lifted right now, I truly don’t want to go out, I want to have an HVAC tech come over and take a look at my entire HVAC machine. With air quality being so critical, I could easily use a tune up, or suggestions on how to make the air quality even better in my home. Since I am taking my air quality extremely seriously, I should get an expert opinion on more techniques I can use for my health and safety.
