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.

Not sure that's true. I am having a problem now with water leaking on the floor from an overflow from the heater. Sam talked to us July 3, 2025, we showed him pictures of the issue. Said he would be out asap to check situation. He blew us off. I'm sure because he knew he put it over the drain and blocked it. End of July 2025 and, after calling , texting, my husband calling, texting , I had to call a different company to come out and found out that Sam from Liberty Heating and Air moved the water heater to a different spot and over the drain so now I have to have it moved because water is flooding the basement and we have to put overflow hose in a bucket. This is going to cost$$$ Avoid Sam and Liberty Heating and Air Ridgetop address. He isn't a reputable service. Sam if you see this review and are honorable and properly take care of the problem you caused we will alter the review to reflect your ethics in correcting your mistake. Otherwise.......the value for your service is minus several hundreds of dollars and your name is mud. Shame on you. Well ,Sam is a good guy after all I said. He called me back, went to the property resolved the issue which turned out not to be a mistake he made but rather our tenant moving the overflow drain out of the drain. The other company said the water heater needed to be moved. Sam showed me proof he hadn't moved the location of the water heater from its original spot that it sat on for over 20 years. The other company could have put the drain hose back in the drain but chose not to. Another story. We are happy satisfied customers! I'd recommend Sam he is honorable. A happy ending.....

This bid was actually less than the competitors, and they had not been around as long as Harster! It was an easy choice. We scheduled to do the replacement in January. Jim and his team came out to do the install and addressed some additional needs to increase the air flow, make the existing unit up to proper code, and make the filter track so it fit filters appropriately. The last unit installation I'm sure was a DIY job or done by a less qualified company. Jim addressed all those issues. I was on a meeting when he was all finished and didn't get to go see the finished product until after he left. It was beautifully done and very neat.
