I have used CGS HVAC both when we lived in Milwaukee 20 years ago and now in our home in Erin WI. They are fantastic!. They installed a new furnace and central air for us in our Milwaukee home and they were the best bang for our buck when we reviewed all the quotes. We were also extremely pleased with the service, quality, professionalism and quick turn around time. We  called them last fall to get a quote for our central air in our Erin home (which has electric heat). We were elated to find out that he could install both a natural gas furnace (using the existing duct work) and replace our old central air at a very reasonable price. We had that done Sept 2016 and have been so happy with our reduction in what we pay we energies. I would highly recommend CGS HVAC to anyone looking to repair, replace or upgrade their heating or cooling. They are extremely knowledgeable and not pushy sales people - they give you options and ideas that make sense. We were extremely happy with their prices, quality and quick turn around time. They beat out 4 other companies that quoted us on a new system. We would never call anyone else! They have truly earned our loyalty

Lost power to the furnace and had no heat. Called CGS as they originally installed it back in 1992, as i found out. 30+ year old furnace final winter. He recommended replacement and was able to install the following day. Clark provided us with 4 strong electric space heaters to help keep our family warm enough to make it through the night and installation during the morning. A part failed from the new furnace within less than 24 hours, and he came back promptly and dignosed and replaced it. What are the chances right. Overall, I am very happy with my experience with Clark and others with him at CGS. Older reviews showed him in a negative light, but i did not have that experience at all when talking and working with him through our situations. Very appreciated for the business and cared about addressing our situations over more than one call in a short period of time. Would recommend.

Three weeks ago, my wife and returned from a getaway only to find out that we were without heat. I called Clark, my HVAC expert for the last 25-30 years, and he promptly came over, assessed the problem and came up with a temporary fix to provide us with heat that night. He followed up the next day to complete a permanent fix and we were eternally grateful for his prompt and efficient service!

I have utilized CGS Heating and Clark Sherman for three decades now, for two furnace and central air replacements, servicing when needed and for periodic furnace and C/A tune-ups. Clark has always been very friendly, professional and honest. You can trust what he tells you and always provides service at a very reasonable price. I highly recommend him & would give him 10 stars if possible!

We're great to work with at first. They did hack one of my plants without permission but I let it go because he explained that they need more room for thr a/c. Project was incomplete, all we need was our April air installed. We waited all summer. When fall came around we reached out for them to finish the project. We were meet with we will call you in a acouple weeks to see where we're at. Long story short this continued on for a couple months. It ended with no call backs one nasty conversation where I was told I was unimportant and that he would call us back in several weeks to see once again where they were at. Finally we just asked for the refund. We were blown off for about a week until finally his assistant came delivered our check and took the part back. I wouldn't hand over all the money until the project is complete!

Clark has the worst customer service or interpersonal skills I have ever seen.

One of your drivers drives like a complete a****** I was going 40 on Landon Road which is the speed limit you passed me going about 60 swerving in and out of traffic then I'm Mequon Road he's been swerving in and out of traffic as well you need to check your drivers

Scheduled a meeting for Clark to come to my house on 6/29/19 to give an estimate for replacing out HVAC system. He never showed or called saying he could not make it. I called and texted him to see what happened but not response.

Horrible service! Clark serviced our furnace and got the unit running. After it failed overnight, I called him the next day and he told me to monitor it as it came back on after I reset it. Once the resets didn't work, I called him back and kept getting excuses and blown off about coming back to fix the unit. Almost a week later and after numerous phone calls and time on my part he finally agrees to come out at noon. Shows up 3 hours late and asks my wife " how much heat do you need?, it seems warm in here." Not amused, she explains we've been running space heaters non stop since he couldn't fix heat from a week ago. He stormed out of our home and told her to get someone else to fix it. I called him as I was at work and he told me he's too old to hear customers complain. You're an infant and a joke Clark! I would rate your service a "0" but that's not an option. A complaint to the Better Business Bureau is on it's way. Stay away from CGS, you've been warned.

The owner is unprofessional and unreliable. He installed the equipment, but then doesn’t answer or return calls, makes appointments and doesn’t show, then flips out when you call another company to help when you don’t have heat. Save yourself the headache
