"Controlling Systems was very easy to work with. They worked with our budget and needs and tried to get us the best price for our unit. When we called with a competitive quote (lower) but wanted to go with them, they were able to add an additional discount. The sales person and installers were both on time and very courteous. They covered the floors to protect them while they worked, and cleaned up after installation. After installation, the installer showed us how to use and maintain the system. We will definitely use them again for maintenance."

"Excellent service! I was lucky enough to get a same day appointment with Nick and he was amazing! He did a great job repairing the AC unit in just minutes. Very professional Company and will be referring everyone to them."

"It went very well, he took the time to explain what was wrong, and he was very professional. I'm going to have him service my AC in the spring"

"Excellent service, very fast response to my request for service, picked up laptop, diagnosed issues. Initially thought it was an OS update issue but the hard drive had failed along with other components (including 'CPU). Because other components were involved, a new solid state hard drive was put into a laptop with a working processor - same type CPU as in the failed unit. The laptop was repaired and returned in less than a week. This company picked up and dropped off the laptop (driving from Huntsville, AL (about 60-70 minutes)-- great service in this covid environment. I would recommend this company to my family./friends and will use again."

"They did a good job. Fixed the AC unit and cleaned the furnace."

"The HVAC specialist performed a diagnostic test of the upstairs unit, and determined that the pressure switch was bad. They then charged us $265 to change the part which did not fix the problem. We were then told that the mother board was bad and this need to be changed as well. They then quoted us approx $1200 to complete the entire job. I decided at this point that I would just fix the system myself. I then ordered a new motherboard a fixed the system for just under $400 total cost including the cost of changing the pressure switch. I honest felt like the pressure switch was never the issue and that I paid the company to change a part that was never bad in the first place. This is solely my opinion and I have no way of truly telling if this part was bad or not. I'm sure the company does great work, but I felt that I was going to continue to pay them to swap parts that may or may not be bad and once everything was said and done get hit with a large bill that I could not afford.

"I was very pleased with the work done. Great company and friendly staff. Would definitely recommend to anyone needing furnace or AC repairs. Thank you!!!!!!"

"Luke warm review is based on their sales and business practices. They play games with words and if you don't know the technical terms your real cost is far from the advertised one.I purchased services via AL for a whole house duct cleaning with unlimited vents for $125. when they showed up to do the work the estimate was over $800. Seems 'vents' means just the cold air returns. They charge addition fees for each element in your furnace-a/c. Supply vents, return vents, what they call a main line, upper unit, lower unit and more are all additional elements with additional fees. The service itself was fine and they do have fine print that mentions additional fees may apply. I just don't like the predatory/misleading advertising."

"These guys are great! I remodel basements and, when I need a helping hand during the busy season, I always call on Justin and his crew! They’ve helped me with upgrading and rerouting ducting, furnaces, AC units, water heaters, and, most recently, a mini split install for a sound proofed media room! They always are friendly with me and my customers, and very knowledgeable on codes and regulations with inspectors! I would recommend these guys to my family and friends!"
