Times are different now, COVID has changed everything.
- You need to start thinking about things differently.
Over the last 30 years our civilization has become more and more based around immediate gratification as well as disposable products. Take cell phones, for example, as something that everyone knows won’t last more than a year or more than one, and yet they accept it. We don’t care about long term, we just want what we want, and we want it NOW! My dad still has the ancient landline cell phone in his apartment from when I was a teenager, that thing is 21 years ancient and still works good as ever. HVAC systems are usually designed to work for a long phase of time, and some of the high efficiency models can last over 13 years. The thing is, for your furnace and cooling system to last that long, and work well, you need to take good care of them. We aren’t used to doing this sort of thing anymore, we just throw things away and buy a new one. But a cooling system is special, but you need to change the air filters, and check the ducts as well as air vents to make sure you aren’t getting accumulations of debris or blockages, then I propose a HEPA air filter, although they cost a lot more they last for almost a full year in most cases (unless you have a lot of pets). Think long term, use your idea sensibly, as well as once in a while it helps to turn the AC off particularly and open up the apartment for a little natural ventilation.
