As everyone knows, an HVAC system is only as good as it’s filtration units. You can pay for a state-of-the-art system, but if you don’t replace the filters, you might as well not have one at all. As a homeowner, I do what I can to make sure that my HVAC system operates at peak efficiency and I am always changing out my filters. The biggest issue I have with this is the fact that the filters are costly and sometimes my local hardware store doesn’t always keep mine in stock. I finally got fed up with all of that and started looking online to see if they were more economical to purchase that way. At first, I tried contacting the manufacturer but they were little help other than telling me what stores in my area may carry them. My next attempt was from places like Ebay, and Craigslist, I found that those places didn’t carry the exact ones, just knock offs or damaged ones. Now, I have found the best place to purchase them. My local HVAC dealer is actually less expensive and they always carry the exact one that I need. I order them in bulk and this only adds to my savings. In today’s market you can find just about anything online and have it delivered to your door in a matter of days, you just need to know that you are taking certain chances when you do this. It has been my experience that when ordering a specific part for things like your car, equipment or HVAC system, you are better off to get those items from a professional company or one that is specific to what you are looking for. Clothing, groceries, and even decorative items are fine, but when it comes to something as important as your HVAC system, you don’t want to take chances. You may find it cheaper, but if it doesn’t fit or doesn’t work, you are wasting your money and time.
