Their service was nothing but professional, friendly, and helpful. Thomas himself called and spoke with me to set up the estimate. I asked that they take a look at my 24 year old water heater while they were there. Their price....literally thousands less then others, professionalism, and ease of working with them convinced me I had a winner so I scheduled both to be installed. Even after the install the service continued when they registered both units with Trane and Rheem and gave me the printed warranty certificates. This is who I'll call when the time comes to replace the furnace.

Thomas came to our house to look at 2 air conditioning units that weren't working. He said that…read moreboth units were out of Freon. The newer unit was frozen over so he said he couldn't figure out what was wrong with it until the ice melted and the other was old and should be replaced. He became frustrated with me when I had trouble understanding what was causing the unit to freeze over if there was no Freon. He appeared arrogant and I was ready to send him home at that point, but my wife was mainly dealing with him and it was a hot day. When I complained to my wife about him she said that maybe I shouldn't have bothered him while he was working and that he was very nice to her. After examining the units he spent a while discussing our options which included a new air conditioning to replace the older one or adding 5 pounds of AR-22 freon for $1100. He wanted to charge $7,500 for the new unit which seemed reasonable, but he couldn't do it until next week and, after a quick Google search, I told him $1100 was high for adding freon. Then he once again appeared upset and asked me what I was talking about. When I explained that I quickly looked it up and knew that It usually costs maybe $500-$750 he conceded that I could find it cheaper elsewhere. Then he told us it was $125 dollars for the visit. I told him that he can't charge me for the visit because nobody notified us that there would be any charge. He said that he doesn't work for free. But I told him that without prior notification of a service charge, I didn't believe it was legal for him to charge me considering he didn't do any diagnostic testing or any repair work. He just looked around and told me something any technician could have discovered in a few minutes. He then while standing in our kitchen played the whole recording of the conversation my wife had with the dispatcher to learn that we were right and we were never notified that there would be any charge. Two days later we had Meyer Heating and Air do a same day installation for the same $7500 and they added freon to the other unit for free when the $333 leak detection didn't reveal any leaks. Plus the reps at Meyer were very pleasant to work with so I gave Meyer a 5 star review and Design a 1 star review.

Climate Masters have been servicing our boiler for the better part of thirty years. They knew what they were doing and were EXTREMELY informative. They showed me how our system worked, they took the time to explain everything from lighting the pilot light to bleeding the radiators. The tech even gave me a key to bleed the air from the radiators. They state they specialize in older homes and they did right by our 96 year old system! Highly highly highly recommended.

After Climate Masters finished the job, I was surprised to realize ... wow, even mechanical systems…read morecould be visually attractive. This was because the installers, Scott and Ethan, did an absolutely meticulous and exacting job. Our house is a 6400 sqft three story built in 1906. During the winter, the hvac system we had in place was never able to properly heat up the home. While driving one day, I spotted one of the Climate Masters' trucks with the motto, "we specialize in older homes" and wondered if they could fix our hvac setup. Tom came to assess and bid the job, and I must give thanks to how patient he was during the process. I took an excessive amount of time to decide, and yet Tom followed up throughout this period. Climate Masters ended up installing a large 140K BTU gas furnace, ran new black iron gas piping, and redid sections of our duct work. Part of the work involved cutting through a kitchen floor with brick veneer. Scott was able to shape the vent opening beautifully. The result was that for the first time ever, the house felt ... toasty during cold weather. When Spire came to activate the gas, servicemen on two separate occasions saw the installation and, without prompting, asked me which company did the job. When I asked why, they both said, "oh, it's because they did a great job!" Everyone I interacted with throughout the process has been wonderful: Scott and Ethan came promptly at 8 am each day and finished a huge job in 1.5 weeks; Doug was great with follow up logistics, and Jennifer always friendly and helpful with office paperwork.

We called Air Excellence due to a minor smell of gas when the heat would kick on. Brad came by and checked our entire furnace out. Made sure everything was looking normal. After he cleaned everything up and put it all back together we ran a few test runs to see if we could still smell the gas. We could and he recommended we call Laclede to get out here and check to see what was going on. I am very thankful he did. He could have gave some bs reason as to why it was leaking charge me an absurd amount of money and move on to the next job but he didn't. Brad stayed at the house until Laclede showed up and gave him a brief run down. After about 3 hours of searching Laclede finally found the leak. I called Brad back to tell him what we found and the part that needed to be fixed. He asked if he wanted me to have him come fix it right then and I told him tomorrow would be fine. Brad got me a quick price quote and everything the next morning and was out the next afternoon. He replaced the control valve in about 30 minutes and was on his way. Overall this was a great experience for a new home buyer. Brads price was amazing and his professional was second to none. I will be calling him for all Ac/heating needs from now on.

We called Hoffman Bro's first because they deal with both, and they charged us ~$300 to tell us the same thing as Spire and suggest we call a chimney sweep to check the flue pipe for blockages. We couldn't find a chimney sweep that either could be booked within the month to inspect and give us an estimate, and if they could be booked in that time frame they didn't understand the problem we described and wanted us to fork over hundreds to inspect and sweep our flue. Luckily, an acquantance gave us Crestside Ballwin's number. The receptionist called Dave over to learn about the problem and within a minute he figured that the roofers we had over a few weeks ago probably botched the install of the new flue pipe cap. They had a tech come over two hours after I called and sure enough that was the problem. Anyhow, these guys were solid for us, I'm super thankful we found them.

The following is a honest review of Aireserv Eureka a company that has stumbled in their service…read morenearly from the moment we bought an Amana HVAC unit from them in August of 2024. The original much more critical 1 star review is below and it is all still very true but they have as of mid August 2025 rectified some of their errors by honoring repairs and warranties that Amana refuses to honor. Does that completely erase all the errors that have been made along the road? Honestly no they do not, but I appreciate that they are currently doing their best to repair what was wrong. They very well might be a very good company but my wife and I's recent experience has been rocky at best. Update to a 3 -3.5 star rating. THIS IS THE ORIGINAL 1 STAR REVIEW. : Based off of positive reviews on Yelp and Google my wife and I chose to buy a new HVAC unit from Aireserv Eureka in August of 2024. In no less than 3 MONTHS our unit broke down, something was literally smoking, due to a failure to install the unit properly. Then in March of 2025 we discovered that they installed a unit that for natural gas, which we do not have, instead of propane WHICH THEY SHOULD HAVE KNOWN SINCE THE PIPES ARE APPARENTLY VERY DIFFERENT. So yet another overhaul was made. Then in June of 2025 we started to notice the coldest we could get the house was 75 degrees. So we called for another checkup and they "supposedly" fixed it, saying it had been improperly calibrated during installation. But one month later, in July, our unit broke down AGAIN. This time completely, leaving our house in the 90s. Now as I right this in August of 2025 THE HOTTEST PART OF THE YEAR they have yet to fix my unit. Week after week, yes you have read that correctly, it has been weeks since we called them to fix our unit, we have had to call them over 20 times. So far we are at week 3 and moving soon to 4. Airserve Eureka's horrible service has so far consistented of misdiagnosis, instillation of wrong parts, incorrect calibration of the unit, and long waits (4+ days) while a part ships. They have given an excuse for everything, always blaming someone else (Amana). According to them, none of this is their fault. They are playing the victim of corporate manufacturing. But, why would you want to reach out to a company who has no control over the services they offer? We then said, since there are so many issues with my unit from the start and I am still under warranty, why don't they just install a new unit. So far they have refused to honor the warranty because Amana won't. I'm not writing this bad review out of spite but as a civic duty to report incompetence in what is falsely sold as good. I hope those of you reading this heed my warning about Airserve Eureka. They are just plain terrible. UPDATE: In mid late August 2025. Aireserv Eureka decided to ignore Amana's horrible lack of honoring our warranty and installed a new RUUD unit. Let's hope this goes better than this last year's trials. I'd definitely not recommend Amana for a future HVAC regardless of the positive reviews they have online. Eureka honestly doesn't deserve a stellar 5 star review but they have tried to do right currently so perhaps they again as mentioned above deserve more a 3-3.5 Star rating.

After over three months of operation, cooling and now heating, I give Galmiche's a good five stars…read more We'd had Galmiche's give us a bid several years ago and were impressed then, however we didn't have the funds and decided to wait and see. Well, this summer as we experienced our hottest heat wave, the nearly 40 year old system finally died. Galmiche's came back out, gave us a new bid and had a new system installed within four weeks of our old system dying. Over a month later the AC wasn't working again. Galmiche's came out, found a problem and fixed it, on warranty. A couple days later the AC stopped working again. The same technician came out, did a deeper dive and determined that a part hadn't been replaced that should have been as part of the complete install. The company warrantied the repair again, accepting responsibility. All in all, I've been very pleased with Galmiche's. Their price, their courteousness, their promptness, and their integrity. I recommend them, and will definitely consider them when our second system (we have a two system house) finally kicks it.

The tech guys got it up and running and I was happy to have heat again. The one problem I had, and still do, is when the furnace comes on it sounds like a train is in the next room. It's very loud. Later I heard a lot of noise in the furnace area and investigated and found a lot of plaster pieces on the floor and a large hole in the ceiling above the furnace. I called the Sales guy, Jim, and explained what I saw. He immediately started blaming me and said they were not responsible for anything. I regretted even calling him. I was not asking him to replace the ceiling, I just wanted someone to look at it. I then called the office and talked to the Receptionist who was so sweet and very nicely told me they would have someone come out and look at it, which they did. I was told there was a small hole, to begin with, and with all the work that was done, it probably messed with the hole. I would have liked it if they could have just covered it up with a piece of wood but it wasn't offered.
