Have you changed your furnace filter lately? If you haven’t, it would be a good time to do it or get it done.
Depending on who you talk to, it’s recommended to change the filter every six months or as often as every month. I have found that it does vary depending on the house, amount of dust, animal hair, type of filter, etc.
The true way to tell is by looking at the filter when you change it. If it is heavy with dust, etc, then it might be a good idea to change it more often.
If the filter is obstructed, the furnace will not work as well and it will cost you more to operate.
Filters themselves vary in cost from fifty-cents on up. Some of the more expensive ones do work better and may last longer. Depending on what you want to accomplish, such as pollen filtering and allergy reduction the more expensive may be what you want. For those you may be looking at ten to fifteen dollars. Of course you can spend way more than that if you want to.
Some furnaces make filter changing very easy; others can be a little more complicated. I will be glad to help you decide on what you need and if it is a job that you can do yourself. Give me a call and you will breathe easier.
