They worked alongside the plumber so he could repair the pipe between removing old ductwork and putting in new ductwork. It wasn't a simple job because they had to remove some dropped ceiling in order to get the ductwork out and in. They also replaced some damaged conduit and replaced the ceiling and trim. They fixed any issues they found, issues I did not even know existed. I could not be happier. Thank you!!

I have been working with this company since moving into the area 4 years ago. After 4 years of…read morecleaning and checking my furnace and air conditioning, I needed it replaced. No pressure at all. They provided multiple options and didn't pressure me when I wanted time to compare prices and products. After I chose Northern Continental, I received excellent work, at a competitive price, for better products. This shows how they service customers for both big and small needs. Different options for my replacement were offered at different price points, all reasonable and well explained. They took the time to answer questions, make a competitive quote, and completed a professional and clean installation on my timeline. I will continue to work with them for routine maintenance, and highly recommend their services. Another very happy local customer.

I was unable to find a spare parts in the same day after many phone calls, so I called TEM control this morning (Saturday) because it had good Google reviews. Tem Control showed up in less than 20 minutes, and confirmed that it was inducer motor issue (took about 5 minutes), and quoted the replacement cost would be $350 ~ $550 (parts and labor). Tem control left my house to get the parts and came back a few hours later to complete the job (less than 15 minutes). so we got the heat back on the same day which was wonderful. But we were charged $520. We were told that we need to paid for the time which Tem control spent on getting the parts.

I am very grateful for the Corcoran team -- and hope that you will learn to depend on them as much…read moreas I have over the past 12+ years. As part of a remodel project, I needed makeup air to compensate for walls and ductwork that would be removed. First, they conducted an on-site assessment of the residence and provided a detailed proposal for their services. Months later they were able to quickly assign a crew to do the work before the remodeling began. Multiple, seasoned team members got the job done well under the time estimated. Professional, kind and thorough, the Corcoran team ensured the automated controller and electrical setup with the damper was in working order and even took time to explain how it was implemented, including placement for easy maintenance in the future. No detail was left undone. They were happy to explain the inner workings to me so that I felt comfortable with how it all worked end-to-end. Their team lead also capitalized on an unexpected opportunity to coordinate their efforts with our remodeler, who was also on-site the same day. He made sure he understood how the makeup air system and damper control could work with the new kitchen range hood that would be installed the following month. The sheet metal fabrication fit and finish on the new ductwork shows how much attention to detail the ownership instills in their team. They care about their craft and doing things right the first time. I continue to be a customer of Corcoran because of experiences like this one. I'm never disappointed and am always left with the feeling like the work was done correctly and communicated respectfully. Kudos to Corcoran for making customers for life!

It took them a day to fix the problem and all the problems the other contractors had created by not understanding how old furnaces work. Comfort Air was very professional, called when they said they would, delivered estimates well within reason and market value, and delivered on their promises on time the first time. If you have an old furnace, call these guys. As a testament to how well they did fixing my old furnace, when I upgrade to a brand-new system with duct work (which my house currently doesn't have), I'll be using Comfort Air.

Nothing special per say but friendly, reasonable and while I was skeptical about the service agreement, It turned out to be a God send. Since that day, I have had multiple problems and every time they send somebody out the same day and always get it fixed. If you have the service agreement, you save a ton of money and trust me, if you live in the area, you will not find a better company. They don't make the prices up, they have listings of what things cost so it's the same price for everyone. This is my HVAC company for as long as I own my house and live in Wonder Lake.

However, once they inspected my system, they claimed it was too old and that parts were no longer available. Within minutes, they were pushing me to sign a contract for a full replacement costing $15K-$18K. I told them I would get at least three other quotes before making such a big decision. They left almost immediately--and I never heard from them again. Not long after, my HVAC system stopped working, and I was genuinely worried it might need to be replaced. Thankfully, I found Proactive Heating and Cooling LLC. Abel, the owner, is excellent at what he does. You can tell right away--from his setup to the way he works--that he is honest and straightforward. He inspected my system and reassured me that everything was still in good shape. He explained that all the necessary parts were readily available and even mentioned that my setup is reliable and worth keeping. In the end, all I needed was a new fuse and filter. Abel also performed a full system cleaning, and now my older HVAC is running as efficiently as possible. Finding an honest HVAC professional is a lot like finding a trustworthy car mechanic--it's not easy, but once you do, you stick with them. I'll be calling Abel and Proactive Heating and Cooling LLC for any future HVAC needs without hesitation.
