I read all of controlling systems reviews after having them fix my furnace and was suprized at some of the pricing issues. I am in the service field also. It is not about the part its about the service. If I could fix the problem I would have just bought the part and done it myself. But I dont have the tools and the know how. Also after checking around I found that Controlling Systems has the best service warranty out there I got 2 years parts and labor for the repair. All the other companys offer 90days to 1 year and only if you prove you have been servicing your system yearly. I was very happy with the service and felt the price was great for the value I recieved. Thank you Controlling systems

These guys are professionals. They are small so they might be booked a week or so out but it is well worth the wait. Also, the prices are very competitive. As with the HVAC industry in general the difference in price from one company to the next can be dramatic. Another nice thing about Controlling Systems is they work together quickly to solve problems. My furnace was in a very obscure position in the crawl space and had to be cut half just to get it out because the gas line was installed AFTER the furnace. No problem. They sawed it into two pieces and pulled it out and installed a high quality 2 stage furnace that has been working very nice and quiet. I have used them for 2 other jobs since and would very much recommend them to others. Thanks to you guys for getting things done right at a very reasonable price!

Had some problems getting the AC as coild as I like it. Called Controlling Systems and they sent Gus out. Gus was very courteous and efficient.. A TRUE professional. If only Gus had 5 or 6 twins that worked at Comcast, then the world truly would be a better place.

OUTSTANDING! It's obvious and a relief (after a few other underwhelming estimates) when an experienced professional - like Brent - provides a thorough examination of the house. He quickly designed an A/C system that could work with our existing forced-heat and duct work. The installation crew was equally professional, and very talented, making quick work of the task. Additionally, they were very pet-friendly, and mindful of the 2 dogs and the gate. A+
