I really wish this was the company that I had called first. I went through 2 other local AC companies and was left with a bill and no return call. This was going on 3 weeks of no AC. I heard of this company when our AC system went out at work. They responded quickly and had the issue resolved that day. I made an appointment online after hours and was called the next day with a better time frame. Charles came out and told me what the problem was and the resolution to fix it. Gave me a time frame and what work would have to be completed.

Couple days later Bob and Devon came out bright and earlier and starting installing my new AC System. I returned later that day to a nice cool house. I really appriciate the level of professionalism that Charles, Bob, and Devon showed. Thank you, MSP

Mike Rock, Indoor Comfort Specialist gets a huge "Thank You" getting us the new Carrier Infinity Heat Pump sooner then we thought and his knowledge on the right kind of unit we needed for our home. Lou and Devon, the service guys also special "Thanks" were very professional and any questions we had were also answered. We definitely will recommend Mike Rock, his team with Gundlach Sheet Metal Works, Inc. in Sandusky Ohio to family and friends. Thanks, Roger and Jeanne

Critical: Quality I am still waiting for Gundlach to repair my split unit. Andy Gundlach turned me over to Webb Supply in Akron Ohio. This is a new unit and I purchased it from Gundlach not from Webb Supply. This has been going on for months. I am getting realy tired of putting up with this. I feel like I'm being ignored. Service: Ductless heating & A/C services

Shout-out to Bob and Devon, awesome guys, very professional and they know their stuff. Showed up early, got my new central air installed. They even called the office and told them we didn't need this certain part and the office called me that same morning to tell me that they are knocking $150 off my bill because of that. That cinched it for me, honest guys and company. Will definitely be a repeat customer, honest and timely, very happy with the whole process.

Excellent work by the Gundlach team of Lou & Devon. I can't be happier with their craftsmanship. They obviously take pride in their work. We had a new Combi-Boiler installed which replaced an old failing boiler unit. The previous pipe work was like a plate of spaghetti. The photo of the new work shows the excellent craftsmanship. They answered all of our questions and were very professional. I would not hesitate to use Gundlach again.

Devin & Seth we're very professional, knowledgeable, timely & great workers! From the moment they arrived until the time they finished they did not mess around! They did a fantastic job installing my furnace in a timely manner! Truest great employees! Gundlach should be proud of their professionalism! Service: Heating system installation

These guys are the absolute best. I hired them to do a very substantial job. New combi boiler, new ac mini split and installing new radiators. Great price. Extremely professional. Went above and beyond in terms of customer service. Charlie Moorhead is the best! Do yourself a favor and hire these guys.
