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.

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 several years of flooding in my basement and seeking assistance from multiple plumbers across…read morethe area, I finally had someone come out who took my issue seriously. Mike was my Drain Tech and he was the absolute best. Not only did he take the time to really listen to my concerns, he was empathetic as he explained to me what needed to be done. Never in my life have I been so happy about having repair work done in my home. I am really looking forward to gaining some peace of mind. Others literally just came out and did what they were asked. If I suggested something or asked what else I could do, I was always greeted with a stale response. I'm a big believer that great service comes from a persons sincerity and how they treat others. Chesterfield Service seriously passed the vibe check. I will definitely be in touch for other things.

Blake was the service technician that arrived at my home this morning to address several plumbing…read moreissues I had, faucet concerns and replacement. He was very polite and respectful while in my home, even wearing protective shoe covers. He arrived at 8:00am as scheduled and spent 2 hours completing a "Home Diagnostic Inspection" which included examining all my hot water heaters and ALL plumbing fixtures throughout my home which I was not expecting. He then presented me with a service plan at $60 per month for a maintenance plan which gave me a discount on future services (10%) and a 50% discount on the service call fee of $119.00. He also gave me a bid on replacement cost for several faucets which I felt was a little bit higher than I was willing to pay. He said I could buy my own parts but the installation charge would be higher. I told him "Thank you but no thank you". He gave me a bid for the removal and installation of the 'Insinkerator' instant hot water dispenser that I had already purchased. The bid was extremely higher than I ever expected! But, the technician was here and I wanted it done, however I only elected to have ONE faucet replaced which made the price go up! Long story short, I was charged $815.36 for the installation which took One Hour and Fifteen minutes (I provided the part). In addition to this, I was charged $119.00 for the service call fee! I paid a total of $934.36 and 2/3 of the time he was here was spent on trying to sell me a service plan for my plumbing, H-Vac system as well as my electrical needs for $60 A MONTH! Then, you get a whopping 10% discount on the service call fee! I calculated that this service call was $12.47 per minute! I contacted the company customer service representative to talk about what I thought was an extremely high charge and all she could offer was that they have to pay for gas, tools and expenses! She also reminded me that I signed and agreed to the bid (she told me this 5 times). I told her I DID agree that that was their bid and I paid it! I did not agree that it was a fair price but I did not want to confront the young technician. I called HER to discuss the issue, to see if she thought that $934.36 for 1 hour and 15 minutes labor was fair. She did! Call this company if you have money to burn but you will get your work done politely.

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.
