I have Used Mark at A-1 heating and cooling for 20 years now. One thing that is always apparent is…read morethat Mark truly cares about helping his costumers, whether it is with helpful advice, or finding his customer the most cost effective way to resolve whatever heating or cooling problem they might have, it comes through that Mark is looking out for you. They will not try to up-sell, or pressure you at A-1, although if he will tell you if you actually do need new parts, or a new system for your home. Another thing that has always stood out to me, is how safety orientated Mark and his staff at A-1 are. If it is not right, or not safe to operate he is going to let you know, even if that means not getting the job. Mark is only one man, and usually pretty busy, but if you want a personable, and conscientious heating, and A/C guy, then do not hesitate to give him a call! Plus he may just have the coolest service van in the business!

I tried to give this company another try. The first time they came the gentleman tried to get me to…read morecash app him and charged me incorrectly. The gentleman charged me incorrectly. I called and spoke to Becky and told her what was going on who said this is not per their policy and not sure why he was doing this. I also spoke to Rocky. They gave me a credit for another carpet cleaning to try them again. I set it up and when I scheduled it they put a note that I didn't owe and had a credit. I was told if there were any issues Becky would call me. Never got a call. A new gentleman shows up today and tries to charge us $70. So I call again. My husband was home, thankfully this was also caught on our cameras, Rocky called the gentleman who then replied to Rocky, "oh ya I remember that incident, that was messed up we lost one of our really good guys & he was just trying to save her money." Really? If he was such a good guy then why was he fired? If he was such a good employee why was he fraudulently taking money on his cashapp instead of having customers pay the company? Completely inappropriate behavior! I can't believe Rocky allowed him to respond that way. My husband was very uncomfortable after that. Never ever using this company again. Absolutely completely unprofessional. It only took him 15 minutes to clean our carpets and he didn't even attempt to dry 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.
