I always have to keep my home sealed up! Living in Springfield, Missouri means that the weather is mostly cold, i have sprung quite a bit of money into making the home airtight, however the windows are caulked plus sealed. The door has insulation around it. The baseboards got reinsulated last summer, however after I closed up my thermal envelope, my heating system was able to be more efficient, but having a sealed home means your utility bills are lower. However, the con to this is that the same, stale air keeps circling over plus over again. I started to feel sick all the time while in the winter. That was because the air was filled with dust, dirt, plus hair. I thought maybe Springing for ductwork cleaning in Missouri once a year would do the trick. It truly helped, along with Springfield heating service. It wasn’t the magic repair though. I ended up needing to get an media air cleaner installed in my household. I can’t open the windows plus doors to let in a fresh breeze. What I can do is use the whole-home air purifier to clean the existing air in the house. It catches all the dander plus hair. It reduces the amount of scents. It uses its own air filter plus requires yearly maintenance just like a Heating, Ventilation plus A/C unit. That sort of smells since my Heating, Ventilation plus A/C expenses have significantly gone up. I can’t truly put a price tag on clean living though. I needed to have better indoor ari conditions plus an media air cleaner was the way to do it.
