"I always trust Chris as my technician to deliver superb service re: my furnace/boiler, hot water tank, split A/C system, and dehumidifier. It's a pleasure to greet him semi-annually, since he's courteous, pleasant, and professional, and since he answers all my questions re: my heating and cooling systems. I trust this talented tech being inside my home and tuning up all these systems. Kudos to Tyler Heating & A/C for hiring Chris as its employee."

"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!"
