Three years ago I had a different company replace the coil on our AC system because it was leaking Freon. I thought that company's price was a little high and I am unsure if they are even still around. I really dislike calling the big AC places that have TV commercials because they often are commissioned and try to sell you unnecessary stuff, It's the same reason I take my car to a local mechanic. Anyway, our AC just did not seem to be working as efficiently as it should, so I gave NASCAIR a call based on Yelp reviews and a friend's recommendation. They sent a guy out who checked the Freon levels, temperatures, main unit, and coil. Everything was functioning normally and the Freon was only about a half pound low. He said that the maximum temperature an AC unit in the Charlotte area can handle is 93 degrees and that an AC unit can only cool to a maximum of 20 degrees. With the hotter than usual weather this summer, it was normal for our AC to be running constantly and not cooling below 80 degrees during the day. Since the weather will be cooling soon, he said he could install the Freon (which is expensive) or wait until the springtime and have them check it again. I chose the latter and will definitely be giving these guys a call. Total price for this thorough service call where I was not even attempted to be upsold anything? 85 bucks. If you need HVAC service, give this company a call. It is great to know that places like this that don't have to put thousands of dollars into stupid commercials still exist. Oh, and the price for the other company that replaced the coil before? Not so bad considering the price of Freon at the time.
