Recommended Customer Reviews

Because Hallmark Heating & Air Conditioning out of Killeen had performed such a botched installation prior to us buying our house in 2007, no one was willing to look at replacing our system because performing an accurate load calculation was virtually impossible. The pre-purchase home inspector never informed us any possible HVAC issues. Even though the house with the original system had only been built in 2003, it had proven to be a total disaster. It never worked right. A true nightmare. After I called an end to the never ending $1500-$2000 service calls every year, we went over two years using five window units on a house barely ten years old. The previous system was so inefficient, even with us using only window units our utility bills dropped from $550-$600 per months down to around $300-$350. To put in a new system, we were looking at tearing out all the original system and the upstairs air handler, a large amount of sheetrock and the original ductwork just to start. I was so fed up I even had the regional Carrier rep travel 2.5 hours from Dallas to inspect the original 2003 install. When he saw our predicament, he just looked down at the floor, shook his head and said, "Who did this?" I said, "Hallmark Heating & Cooling out of Killeen." The guy that worked on the original install was standing right there and tried to worm his way out of saying he had anything to do with it even though I distinctly remember his involvement because of the earring he wore when he came out to answer numerous service calls. When we called Lochridge Priest to come out they wouldn't even give an estimate. Bottom line? We took out a HELOC, I got a few estimates and pulled the trigger with 3C Mechanical. Good God!!! They kicked butt. They removed all the old system, put in two new Rheem units, balanced the system and were in an out in less than a week. The entire house is now perfectly comfortable at higher settings than before. Our first utility bill was $196.00. WOW!!! They're professional, extremely knowledgeable and very efficient. I cannot recommend them highly enough, really. Not to mention, at under $15,000 for a serious system, they were less than half what Sears wanted. Well worth the money. Give Bill & Daniel Curry, the father and son, the opportunity to prove themselves and I can promise you won't regret it.
