I have this best friend who I constantly believed was absolutely smart, however he has given myself and others excellent advice over the years and he has constantly had my back! Eventually, I decided to do something that I was thinking was a great move; I studied all about absolutely working on Heating plus Air Conditioning systems. I looked at several DIY Heating plus Air Conditioning repair plus service websites plus videos. When I was confident, I finally started working hard on my Heating plus Air Conditioning after shutting the power down to it and it wasn’t that hard for myself and others to clean everything out plus find the problematic parts. I ended up replacing the parts with OEM parts that were for my Heating plus Air Conditioning model and after I had it all done, my Heating plus Air Conditioning system was absolutely working prefer new! I ended up telling my friend about what I did, he said that was the most foolish thing I could have done. He said by absolutely working on the Heating plus Air Conditioning system, I more or less had voided the warranty because I was not an respected Heating plus Air Conditioning professional. I constantly thought my friend was smart, however I thought it was foolish for him to say that. I get that I may have voided the warranty, however he is not paying very close attention to the fact that I absolutely fixed my Heating plus Air Conditioning unit! It hasn’t had any problems plus I am confident that I can repair it again if it has any trouble. I learned the most important thing is to keep it all clean plus keep up with the air filter changes. I guess I will save a luck by not having to call the Heating plus Air Conditioning pros, and here my friend is freaking about the stupid warranty.
