Airnizer is the best. We have had trouble with our hvac over the years and they are quick, honest, and patient. All their technicians are great (though Sergey and Alexis are favorites). We bought a replacement for one of our machines through them and we couldnt be happier! Today they did a service call on a different machine with quick turnaround.

We had an extensive leak situation with our HVAC system and were lucky to have Aleksei save the day for us! He worked with our schedules, diagnosed the issues quickly, and was able to get our system clean, working, and no leak several days later. It was a full day worth of work and he kept us informed and updated throughout. Would absolutely recommend him if your HVAC system needs to be serviced and youre in a pinch.
Airnizer HVAC's reply
Thank you very much for your feedback, Katarina! It was our pleasure to meet you and perform nitrogen pressure leak test and leak repair as well as regular cleaning of your concealed ducted Cooper & Hunter mini split system. We will be happy to assist with any of your HVAC requests in the future.

My experience with AIrnizer HVAC was totally positive. Everything they did, from setting up an appointment to obtain an estimate to replace an old mini split, to the installation and clean up was done professionally. They were quick to send someone to evaluate my residence for an estimate, and thorough in their assessment. They were foremost in pursuing the job, being timely with their communication. The workers were personable and excellent at their jobs. Amazingly, they also came in with the lowest estimate. I would highly recommend Airnizer HVAC for all you HVAC needs.
Airnizer HVAC's reply

We are glad to hear that our team provided a professional experience during your ductless mini split replacement, from the initial assessment to the final installation and cleanup. We strive to provide thorough, timely service and competitive estimates for all our clients. Please reach out if you need any future maintenance or heating and cooling assistance. Regards, Airnizer HVAC

Definite 5 star experience! I had never serviced my split units. I was given the pricing of both regular and deep cleaning. I didnt realize how expensive this could be! I was told that once they assess the machines they will provide the actual cost based on how dirty they were. I assumed I would need a deep cleaning on all because I had never done a service. If the cleaning was completed on the same day, the assessment fee would be waived. What I am most impressed by is their professionalism and honesty. It turned out that 2 splits and the compressor needed deep cleaning and the other 3 splits regular. Another company may have said deep cleaning all around and I wouldnt have known the difference. Despite the language barrier my tech Alex explained EVERYTHING via Chat GPT and my system is squeaky clean! I am grateful that we went with Airnizer!

Thank you for the fantastic 5-star review! We truly appreciate you highlighting our team’s professionalism and honesty. It’s wonderful to hear that Alex could clearly explain everything and that you’re happy with the results. We’re grateful for your trust and glad we could provide the right service for your system. Please don’t hesitate to reach out for any future maintenance needs. Best regards, Airnizer HVAC
