It's too complicated. You need a new system anyway- it's old" said I needed a complete replacement because they can't service my air conditioner anymore - wanted to sell me a $10k unit. Branden came over and did a long look at my unit and agreed that it was an electrical thing- apparently he WAS willing to figure out what was going wrong- got it going again and said when it stops working again to call him so he can figure out where the wiring needed replaced. Spent a long time at my house. Well, it went out a month later and he came over and did everything he could to figure out where the wiring problem was. Took a couple visits and lots of trial fixes. Said he could service my AC just fine in the future and fixed the issue- everything working again. He also has lots of options for when I do need to replace my older system- but it's not now. Very conscientious, very knowledgeable and very patient and tries very hard to fix the problem without taking shortcuts and not wanting to do the work cares more about the customer than making a big sale.

Nice guys, BUT get ready to overpay for a repair…read more.. They came out to address a noisy/failing inducer motor. They made the repair, and it took them just 1 hour. They charged me $1925 for the repair. I paid the bill, but couldn't understand how the charge was so high. I did some research, even calling the Lennox parts warehouse where they purchased the part. The part costs anywhere from $600-$700. The Lennox parts warehouse couldn't tell me exactly what they paid (w/o their acct #) but said the cost was "not even close" to $1000. That means they charged me over $1200 for an hour of work...unreal. The owner claimed they have a pricing book that dictates their prices - obviously to their significant advantage...not the customers. I asked if he would reconsider their charges, but he would not. Again, they seem like nice guys...but their pricing is very high, and I feel is dishonest. I will not (can't afford to) use them again.

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.

A neighbor recommended Welsch to me and I could not be more satisfied . I have a big home with 3 air conditioners and 3 furnaces, so I rely on them to keep working. Colin is our service person, and he is "the bomb". He is always on time, extremely good at what he does, very very thorough, and respectful to not only my husband and I, but treats my house respectfully also. I have one unit in the attic, and he never complains about crawling up that ladder in the heat to check it out. My pricing is a bit more due to the number of units I have, but the quality of service and respect is so worth it.

I've used Welsch for over a decade and my family used them before that. So my experience runs deep. First thing you should know: their technicians stay. Meaning you benefit from their experience and commitment to Welsch's service standards, which are high. Recently, I had a blower motor go out. Jeremy came out within the hour (after hours), diagnosed the problem and had Scott on the phone to check inventory. It wasn't easy but Scott was on the phone at 8 AM, ready to set up an appointment to install the motor - less than 12 hours later! Incredible. Look, you might find cheaper but you won't find better service, more knowledgable technicians and an overall feeling of "We got you!" like you do with Welsch.

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.
