What our customers say

“A friend recommended Thaine and True Heating 2 years ago when our a/c quit working. He came and explained to us in simple terms what was wrong and that we needed a new system. The price was reasonable and the ordering/installation process was super fast and efficient. We just purchased a new home this year, and had to replace the entire hvac system. We again called Thaine and he explained again why the system that had been installed was the wrong one and sold us exactly what was needed. Again ordering/installation process was smooth and efficient. Our realtor was impressed by Thaine and said he would use/recommend him to future clients if needed. We are happy with our system and the service is first rate.”

“So if you like top shelf red carpet services then this is the company to do your install and home hvac services. We had a complete install done and from start to finish it was amazing. We couldn’t be happier with how it went! Not only was the work done professionally, and timely. But any questions were answered, and whenever we had one all we had to do is call. You don’t get this kind of service anymore. We called about our old system (which was severely outdated and ready to go.) and boom we’re sitting in the house with a new system. These guys take care of their customers. Even after it was done I got a phone call checking in to see if we had questions. Great company from start to finish.”
