"Oct. 6 2025 it went quick. I received an estimate of The job first. The work was done correctly. It didn't take long. If I need plumbing service again. I would contact Cassidy plumbing & Heating."

"While out of town, got word basement might be flooded. Called Schede to check boiler and hot water heater.. They went out the same day. Discovered sump pump wasn't working so replaced it. Cost pump and labor $800. Over the years they have responded to many problems, leaking faucets and stuck drains. Biggest project replace boiler for steam heat. Took 5 guys to wrestle boiler down a narrow basement stairway. Patient with a few family disagreements. Nothing to do with them. Installation successful. They've always been prompt courteous and non judgemental when encountering crazy working conditions. Think they are great. Boiler and hot water heater were fine. They installed both."

"They were great! Even found a way of adding a 40 gallon water heater to a smaller space. Which has been wonderful! They worked in a VERY tight space and got the job done! I highly recommend them! Will be using them to install my central air as well!"

"I had an emergency heating pipe leak on a Sunday afternoon. Bill was able to walk me through turning off the water over the phone, got to my house in a reasonable amount of time, and replaced a pipe that was very difficult to reach in the wall. We definitely appreciate their help!"

"I thought they were on the high side. The only problem that I've had with their delivery is, they brought oil when I didn't think I needed it. If I have a full tank in April, I don't them to come out until the fall. I don't have to be here when they deliver the oil, they show up on the day. I don't have an appointment."

"As a first time home owner Schede plumbing has been very responsive and professional. Schede plumbing oversaw the oil to gas conversion and installed a new boiler. As stressful as this was and every other plumbing issue in our home, Lou has always answered our calls even after hours to troubleshoot what could be going wrong. If we can't fix the issue over the phone there is someone at our home the next day. His staff, specifically, Kelroy have nothing been short of exceptional. Kelroy always comes to our home with a smile on his face and will not leave till the problem is fixed. Plumbing and heating is the last thing any homeowner wants to deal with but Schede and Kelroy make it an easier pill to swallow."

"I looked at over 10 different mini split installers over a year and had just about given up. It wasn't until I found Kelley's Heating & cooling. They were honest up front and worked directly with an electrician (who also did an amazing job!) to quote me the best price. Mariana in the office worked directly with me to ensure I got all the Energize CT rebates pre-approved and factored into my quote. By far there team was light years ahead of all the other installers I met with who didn't even include electrical. The fact that they are Fujitsu certified was also a big win in my book. I can't say enough positive things about the installation team. They were professional, clean, and organized. Within about 4 hours they had my new mini split wired in looking great and sounding super quiet. Would highly recommend this team."

"Thorough explanation, great service, neat installation and competitive pricing. Would hire again."
