"Dean completed the job professionally and at the stated price. The project required some ingenuity because the tight space. The whole house humidifier has made the rooms more comfortable for sleeping and less of a concern for our new hardwood floors."

"The repair was made.  Sean, the service tech was courteous and professional and obviously knew what he was doing. He replaced the circuit board which took less than 1/2 hour and for that I was charged $597.00. Thinking that the circuit board was pricey (Sean, the service tech indicated so), I thought the repair bill of $597 was reasonable.  Only after calling some stores (the next day) and finding out a circuit board cost $125 did I realize I got ripped off. Controlling Systems labor charge for 1/2 hour work amounted to $472. I called the owner/guy in charge to request a refund for part of the labor charge. (I really didn't expect to receive anything) Not only did this person(whose name I wished I remembered, I would state it here) not want to hear my complaint, he hung up on me because he knew he ripped me off. He was rude and didn't want to hear my complaint. He obviously didn't want to hear anything I had to say, only stating that I agreed to the repair charge beforehand. To that he's correct, I did agree to the charge but when I asked Sean what was the cost of the circuit board, he said  $250-300. Now I know parts are marked up when purchased through a company such as CS but I still believe this company took advantage of me. ( and probably hundreds of others out there). Controlling Systems did not provide parts cost, labor costs, etc in their estimate which they used to (I had used them 3 years ago, but I won't ever use them again) Future potential customers take heed: I WOULD ALWAYS REQUEST THE ESTIMATE REPAIR BILL BE BROKEN DOWN to parts cost, labor cost, etc. And if they tell you they can't provide that, that's a good sign you're being overcharged.
Normally I am careful about negotiating and reading the fine print, etc. but this day I was distracted and the temperature was in the teens. I wanted the furnace fixed and I didn't have time to get estimates. Also if I hadn't  used Controlling Systems I would have been charged the $100 diagnostic(service) charge. Lastly, Sean intially quoted me $700. When I told him I was going to get other estimates, he lowered the estimate to $597.

He provided exceptional, professional service with a same-day response that saved me over $1,000 compared to other estimates. Tyler is remarkably honest and efficient, making what is typically an intimidating process entirely seamless. He came highly recommended to me, and I will certainly be recommending him to everyone I know."

"I purchased a Groupon to have the vents cleaned at the home my husband and I just purchased. The Groupon included cleaning and sanitizing 12 regular and 1 return vents. Our house has 14 regular and 3 return vents. The cost to clean each extra vent was very reasonable. The provider arrived on time for the service and went through the HVAC system with me. Our house was built in 1982 and the supply and return ducts had never been cleaned. Ever. Boris was able to create access panels and clean all supply and return ducts while at the house. He showed me before and after video and the difference was night and day. The insides of the ducts were disgusting. Basically an 8-inch layer of compacted dirt. He also cleaned the dryer vent while at the house. He showed me the inside of the vent before cleaning. You couldn't see from one end to the other because of the dirt clogged inside the tube. I'm surprised the house didn't burn down before it went on the market. 

Basically, I purchased a deal for vent cleaning, and ended up having my entire HVAC system cleaned. This took around 2 hours. Boris was very professional and explained everything well. The extra services I agreed to were definitely needed, and very reasonably priced. 

Somewhat related, when we purchased the home, it smelled. The previous owners had 2 large dogs and the carpets were filled with urine stains. The dogs had been doing their business inside without proper cleanup (not just a few spots. Most of the carpet was ruined) and it took a lot of vinegar, baking soda, and rug doctor rentals to get the smell out of the carpets. After using a steel brush to saturate the carpets with vinegar down to the padding and subfloor, letting it dry, making it snow with baking soda, vacuuming, and making 6-7 passes in each room with the rug doctor, we were not bombarded with urine smells every time we walked in the house. But the smell still lingered. After having the HVAC system professionally cleaned, the smell is finally gone.

So. Great service, no more fear of the house burning down, better air, lower energy bills, and no more dog urine smell. Basically a win all around. I will definitely be using this company in the future."
