Now, I was faced with recovering in a hot, uncomfortable home. Hornbuckle's team was at my house 30 minutes after they opened to do a diagnostic and had the part ordered the same day. They were sympathetic to my situation and prioritized fixing it as soon as the part came in. I only had to wait a day. They were not only professional but cared about me personally. That is so rare with businesses nowadays. I have used them before and will use them again. I can't recommend them enough.

And almost all the piping they replaced is rusted with black spray paint to attempt to hide the rust. The owner David said that this is normal. But Google states that it's a hazard and is more likely to lead to another gas leak in the line. David also stated that charging me $120 an hour is normal. When both their website and every other hvac and plumbing company states $100 an hour. Did this company feel like ripping me of and putting my life at risk so that I would need to get the gas lines replaced again? I can't say for sure. But if this company changes your gas lines with rusted or spray painted piping then please demand that they use piping that is not old, damaged, rusted or spray painted. I will have a different company look at the work this company did. If they believe that the lines need redone for safety reasons then David will be seeing either a bill from me for the damages or I'll just take his company to court over the matter. ​
