When I was growing up I like to spend a lot of time with my dad watching him do home repairs and maintenance. It was a great way to get to know him better and learn how to take care of the house myself one day. One of the things I’m in charge of is taking care of the filter changes for our HVAC system. I always make sure to purchase to filters when I go to the store and that way we always have a backup. I changed the filter out just 2 months at all and already are smart thermostat is telling me that I need to do that again. The thermostat is great because it monitors the systems performance and allows us to log on and adjust the temperature settings even while we are away. I thought something may have gone wrong with the thermostat because there was no way I would need a new filter just two months after changing it. I went to check it and sure enough the filter was really filthy. I tried to figure out why it would have become so clogged so quickly and went over my head everything that we have been doing in the house during the last couple of months. I then started thinking about my husband’s newest hobby that involved making plaster molds and selling them at a local market. Because the weather was cold, he had been working in the spare bedroom and the only thing I could think of was the dust from the project was being sucked into the HVAC system. I asked him to make sure that the air vent was closed when he was in there working and told him he could use a portable heater if you needed instead. The filters on the HVAC system are very expensive and it was cutting into the profits from his little projects anyway.
