Best Heating And Air Conditioning in Saint Louis MO

Dunn Heating and Cooling was happy to help me out in a time of emergency (furnace went out on a Saturday morning and I received help at around 8PM that evening). The technician who helped me, Brett I think was his name, was extremely knowledgeable and helpful at a time of day that surely was inconvenient to him. My furnace was back up and running that evening, made possibly only with the help of Dunn H&C. Would recommend to a friend!

I've used these guys many times. Never an issue, pricing and repairs are honest. They don't upsell you to put in a new system, they repair what you have.

I purchased a very expensive boiler (20k) last winter for them for our radiator heat.  They came to try to fix the old unit and said that our only option was a new one.  After some debate, we moved forward.  The installation itself was OK.  They left the basement door open for most of the time, and I had to ask them several times to close it because we were freezing.  I tried to ask them how it was going while they installed it, and they would barely respond.  Given the cost, I don't think this was unreasonable.  After the install, it stopped working completely after about 7 days.  I was pretty upset. They sent out a technician off hours who had no idea how to fix it. It turns out that the reason it stopped working was because the exhaust valve was installed incorrectly.  Apparently, it wasn't windy the day of the install, but there was more wind later on, so it needed to be installed differently.  Yikes. It works well now in terms of heating up the home.  I will say that the cost savings from this unit were not at all what they told us. The salesman made all sorts of claims about all the money we would save to run the unit.  All of that wasn't true.  It is cheaper to run our forced air units (although the radiator heat is much better; it heats evenly, there is no dust blowing around, etc.). We do love the radiator heat, but it isn't cheaper.  Maybe it is cheaper than a 50-year-old boiler, but he knew that wasn't our situation.  We weren't using the radiator heat at that time, which is why they were there in the first place.  All of this was really disappointing, but today, after switching back from Hoffman, I had someone out for a separate issue, and he was asking me about the unit.  Apparently, we could have gotten a similar unit and used it for our hot water as well.  He said it would have been another ~$1,000 (compared to getting a new $3000 water heater).  I remember the salesperson mentioning that as an option very briefly, and I expressed some interest.  I don't really know what happened in that particular part of the discussion after that, but at the very least I didn't understand the options, because it appears like it would have been a no-brainer based on what I am hearing today.  I have no idea what to believe on this particular issue, but it just added to my overall disappointment about the experience, which is why I am writing this review.

My technician Tom was excellent. On-time courteous polite clean very nice young man.

I contacted Norman and his team to help with work we needed done on our new home. They were extremely knowledgeable (about all issues I was dealing with) and found several solutions that were VERY reasonable. They genuinely cared about the safety of our new home and made sure the repairs were done correctly and up to code. In summary, Norman and his team were professional experts in all areas and most importantly in my opinion, honest and extremely fair in price.

Nick was exceptionally polite and respectful of our time and home. He answered all of questions regarding our system. Then even gave us a few recommendations as well as what to look for regarding diagnosis and upkeep of our system. Would absolutely recommend him as your tech and Hoffmann.
