Customer Reviews

We had Welsch replace one of our old air conditioners, air handler etc with a new Lennox! The whole process from estimate to completion was first class!!! Will definitely use them again!


I have always received good service from Welsch. Today Brian C. came for my annual furnace service. He was very professional, yet friendly. He happened to arrive at a moment of crisis, as the float broke off of my sump pump just a few minutes before. He was extra patient, and even looked at it to give me his opinion whether it could be repaired, or if he agreed with me that I needed a new pump. It only took a few minutes, but it I was thankful, as I know he has a busy schedule. His customer service was exemplary.

Steve W. arrived on time. He cleaned out the air filters and showed me how dirty they were. He checked the outdoor AC units and cleaned them out. Said there was a lot of pine needles in them. One of the AC units was slightly low on freon and he suggested we keep an eye on that in the future. Steve was very engaging and pleasant and explained everything he did. I have used Welsh Heating & Cooling for many years and would highly recommend them.

Dependable service. I have worked with John for several years. He is nice and always on time. I trust his advice. It is reassuring to have someone who knows my home system so well. The company has always been responsive to my heating and cooling needs and they are very friendly. I love that they are a local company as well.

We called Welsch to provide a second opinion after another service provider recommended a new furnace. The technician was not only professional, prompt and courteous, he was unbelievably thorough! He insisted on combing through every aspect of our furnace to diagnose a problem, and found one in the most unlikely of places. (It seems a June Bug had gotten trapped in part of the apparatus that controls the air flow, and as a result, it was causing the system to malfunction.) He removed the dead bug, and our furnace has been working ever since. This was well worth the price of the service call, and we will most certainly use this company for our future HVAC needs.

We got four estimates and two of them were pretty high and two were very close, Welsch being one of those. But at the end of the day I was very happy with Welsch and the amount of time they took to figure out the right size AC and Furnace for us. I felt they were very honest and had been in the community for decades. My home is much warmer now!

The team did a great job and provided exactly what we needed for our home.

Mike P.

bought the Annual Maintenance Agreement $178.95 for 2 visits per year. The A/C and heating system was checked and filters were changed as needed.

Our family tried 4 other company’s in St. Louis to replace old boiler and three AC units for a 4,500 sq. ft. , 100 year old home. It was a VERY complex project involving a lot of thought and creativity. The project was also completed a week before its expected length.
Rick worked closely with our family every day and was very knowledgable, but most importantly, he is a great person first!


I wanted to take a moment to express my gratitude for the outstanding service I received Monday from repairman Chris Sasse. Chris came to my house Monday morning, shortly after reporting a non-functioning thermostat. (We had no heat for 24+ hours.) He replaced the 1+ year old iComfort Wi-Fi thermostat, AND made sure everything else with the furnace was in tip-top condition before he left! It was reassuring to find that using Welsch Heating & Cooling was indeed a very wise decision!

I could not be happier with my decision to use Welsch.

Jeff C.

I was very happy with the prompt, professional service when we purchased our new furnace. All options were presented in a clear, concise way. I would definite recommend Welsch.

Mary H.

We have used Welsch for over 30 years and have never had any problems. I recommend them highly. Very fair, prompt, friendly people and competitively priced.

Rick did an outstanding job of assessing my needs, making appropriate suggestions, and fielding follow-up questions in a timely manner. The install crew was efficient and completed the install by early afternoon. While the crew did remove all the old components the basement floor could have used a sweeping – but I did add five sheet metal screws to my collection. I liked the rigid PVC drain line rather than the old hose drain line. The inspector suggested adding a bead of caulking on one furnace seam and twice mentioned “these guys do fine work”.

I have used Welsch Heating and Cooling for over 17 years. They are always responsive and very helpful!


Lost air conditioning on Labor Day weekend when it was high 90’s. They actually came out on Labor Day and found the problem. It was the blower on the furnace. Serviceman recommended that I replace the furnace, which I did. The cost to put in a new blower was almost half of a new furnace which was more efficient. The day after Labor Day they were there first thing in the morning and installed the new furnace. They did not cut corners and the install was done correctly. I also used them in the past for a new air conditioner and had the same excellent service. Would use them again if needed. Very, very satisfied.


I felt the need to write and praise your company! I have used Welsch for almost 15 years for heating and a/c maintenance and service. I had a slight emergency today, called this morning and you had someone come this afternoon. Chris Sasse was the technician and could not have been nicer or more helpful! In this day and age, I find it remarkable the integrity and commitment to customer service and satisfaction of your company. Thank you so very much! You have a customer for life!

Purchased a new air conditioner and furnace and was impressed from the initial sales contact, to verifying what we needed, installation and clean up. Everyone we dealt with did a great job and we love our new system.

Kara L.

Welsch did a great job installing our outdoor a/c unit and replacing the coil. Quick, professional, polite and treated my fiancé with respect. Really appreciate the work they did.
