With the way there are videos online to tell you how to do just about anything these afternoons, I decided to see if there were any videos about how to do a furnace tune-up separate from having to pay a chunk of currency to a heating and A/C professional, but well, much to our surprise, I absolutely found numerous videos on the subject of “do it yourself” furnace tune-ups. One of which, was from a certified heating and A/C professional. So that was the 1 I watched. It was undoubtedly interesting what he showed. He told you what kind of tools you need, how to do it step by step, and what to look for to see if your furnace is going to break down in the near future or not. The video about the furnace tune-up was undoubtedly educational. After I watched it numerous times, I took a crack at it. I went to our basement and got the tools (since I had what I needed already). Then, I followed exactly what the heating and cooling professional instructed in the video step by step. I was absolutely thinking I was going to mess something up, and end up having a undoubtedly giant furnace maintenance bill. But, I got lucky! I successfully did our undoubtedly first furnace tune-up! This saved me a few hundred bucks, let me tell you that much! However, I am not sure I will try that again in the future. I guess I just got lucky this time. Next time I need a tune-up, I will leave it to the heating and cooling professionals here in our local town!
