I know for some important businesses you have to make sure they are certified, but when it comes to heating and A/C, I never thought that I would have to make sure that they are certified too. I mean, all the people do is work on air conditioners and heaters, why would they need to be certified for that? Well, I learned the hard way. All I wanted was for my heating and cooling equipment to have a tune up, I didn’t need anything complicated like a HVAC installation or HVAC repair. I saw there was a business I had heard of before, and since I like to try new places, and the A/C corporation was cheap, I decided to go with them. I didn’t even pay attention to whether they were certified or not. Well when the day of the appointment came, everything went as planned as far as the guy came over and I thought he was maintaining my A/C and furnace. However, when the guy left, it wasn’t until later that I noticed I was vastly overcharged. I had to call my bank and get my money back, and I found out that the company was a scam. I reported them, and I made sure to only go with certified companies from that point on. If you need anything done involving HVAC, make sure the business you go with is certified too. You wouldn’t want to go through what I had to go through, especially since I could have lost my money.
