Kero HVAC is an Auburn-based heating and cooling business that customers call for air-conditioning diagnosis, repair, installation, heat-pump work, and ductless mini-split service. Angi and HomeAdvisor identify the company at 14 Robert Avenue and list five years of experience; the BBB profile also matches the Auburn business and lists heating and air conditioning. The written reviews, dated 2021 through 2023, repeatedly describe quick response and clear explanations. In a 2022 Google review, a homeowner said Kero drove to the Cape on a Saturday night during a hot spell, priced and installed the needed work quickly, and saved the summer. Other dated reviews describe next-day diagnosis, arrival within an hour during a heat wave, numerical proof of a problem, and discussion of repair options and prices. There are important exceptions to ask about before booking. A 2022 Angi reviewer said a hose was reattached but a promised part was never installed and calls were not returned; the reviewer hired someone else to finish the job. Two 2021 Angi reviews also describe paying for work that did not finish, including a thermostat installation, while another 2021 reviewer called Kero an “a la carte technician” and advised confirming exactly what the visit includes. This looks best suited to homeowners who need prompt HVAC troubleshooting or repair and want options explained before work begins. Confirm the exact scope, parts, completion responsibilities, and price in writing—especially for installation or multi-step repairs—before scheduling.
Kero responded promptly and gave me all pertinent information up front. He communicates well and promptly and doesn’t pressure for services. He explains the options and the pros/cons. I highly recommend his services!
Kero was very efficient and very affordable. His professionalism was like no other and I would highly recommend him.
He did what he said he would do with no issues. Would definitely use again in the future.
1. Kero, answered the call and that in this day and age tells me something about his work ethics. They are excellent! 2.He tried to help me diagnose the issue immediately over the phone on a Sunday. Rather than reading a “script” telling me that “without seeing the unit he could not help me” Which is what we are all used to these days. 3. He made an educated diagnosis by the information that I gave to him. Speculated about the cost of the part and the amount of time that it would take to fix it. He was right on! 4. He showed up when he said that he would. He fixed the unit as he said he would. He was his word to me. He also gave a follow up courtesy phone call to check on the unit. 5. He was friendly, polite, clean and professional. I would highly recommend Kero Menas to my closest friends and as a matter of fact i already did.
KERO drove down to the Cape to look at the job on a Saturday night! Our AC was out on the hottest day of the summer. KERO priced and installed quickly and saved our summer.
