If you ever need work on your heating plus a/c machine, don’t do what I just did. My number one tip for you would be to make sure they are a certified heating plus a/c specialist, then don’t just take their word for it, otherwise, you might get in a awful situation like I am currently in! Right now, it is above 90 degrees outside, on the fast track to over 100 degrees, then and outside, I have a broken a/c equipment that has parts everywhere. So let me tell you a story of how I got myself in this mess; When my A/C broke down a few afternoons ago, I wanted to save money as much as I could. I knew A/C repair is quite upscale, especially from the local heat plus A/C corporations. So I wanted to see if someone online could possibly do the HVAC repair work. Well, luckily, or should I say, unluckily, I found someone who claimed they were a professional cooling specialist. My fatal mistake was paying them ahead of time. As soon as they arrived at my home, I paid them up front. Then I let them get to work on my central A/C. Oh, what a mistake that was. This supposed HVAC worker was successful in taking apart my central cooling device, however that was in. They then left, leaving me with this mess. And now I am hundreds of dollars short too. I can’t believe this happened to me. Next time, I am certainly getting a certified cooling worker, I won’t let this happen again.
