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.

Jake even took the time to explain different packages. Originally we weren't sure which one to choose but Jake spoke highly of each one not making us feel less then for not choosing the highest or making us feel the lowest package was bad. If you know what I mean. When contractors try to upsell. Jake was thorough with all and the positives of each. There was a misunderstanding with the system we chose since we wanted zoning for specific rooms, but Jake quickly upgraded our equipment at no additional cost. He went above and beyond to resolve all of our concerns and even helped connect us with an additional contractor to address the lack of insulation above our garage. Overall, Jake has consistently provided excellent service and support for our family, our needs and our home.

He assessed our unit quickly and professionally (bad capacitor and a bad wire) and promptly had our unit back up and running within a short time. I was impressed by his knowledge of AC systems, his honesty, and willingness to educate me through each step of the repair process. He also thoroughly checked the unit inside and gave recommendations to keep it running efficiently. The price was reasonable and there was no after-hours diagnostic fee that most companies charge. I highly recommend Brandon and will use his services in the future, as well as refer him to family and friends.

Brandon kept going on and on being demeaning, disrespectful and unprofessional. I was very hostile.
