I don’t know a single person today whose day planner isn’t filled to the brim. Everyone I know has a crazy busy life. Some people say it’s because of our modern lifestyle–I say it’s because we all have to work a ton of hours to get by. Whichever it is, one thing is for certain–we can be a forgetful bunch nowadays. I don’t think it’s anyone’s fault; our brains can only deal with so much after all. That’s why I keep both a day planner and a calendar, as well as set periodical reminders on my phone. That way, I don’t forget the important stuff, like taking my cat to the vet or changing out the air filter. Even though I don’t have central AC, I still have to deal with air filters because I have a gas furnace. If you have a boiler, you’re pretty luck in that your air filter is super easy. Boilers use pipes and heated water or steam, so they’re actually a lot more reliable and easy to care for. Furnaces typically use some method of forced hot air into a system of ductwork that pumps out air through vents and registers. All of that ductwork means that you have a lot of places for dust and debris to hide and build up. Just like a central air conditioning filter, I change my oil furnace filter each and every month. Replacing the air filters as recommended by your HVAC maintenance is one of the most important steps in the longevity of our central heating and air conditioning. Caring for the air filter, as well as scheduling bi-annual HVAC maintenance, can work to extend the life your heating and AC equipment, as well as save you money.
