Ann and Vincent always buy air filters for their central heating and air conditioner on the internet.
- The reason they do this is because you can buy them in bulk as well as get one heck of a discount on them this way.
Most of the time when they order the air filters for their central heating and air conditioner they arrive on time when the website tells them they will be arriving. However the last time Ann and Vincent bought air filters for their central heating and air conditioner they were late arriving. As a result they were also late in decreasing the air filter of their central heating and air conditioner plan unit. Unfortunately, they were completely out of air filters because they ordered later than usual, and just their luck the air filters that they ordered for their central heating and air conditioner were also late in arrival. They were late by almost eight days, and so that was eight days that Ann and Vincent had a used up air filter in their central heating and air conditioner plan unit. Thankfully, it did not do any damage to the central heat and air conditioner device or the air quality of their home. If Ann and Vincent had let that air filter rest unchanged for seven days or so, there may have been the beginning of some drastic complications with the air quality, followed by their central heating and air conditioner starting to overwork itself. That could have led to a drastic heating and cooling breakdown and cost them money in heat and air conditioner repairs. Ann and Vincent did not want that.
