0 Stars If you enjoy sweating through a 30-day summer heatwave while your AC sits broken, Aquinas HVAC Inc is the company for you. It took them an entire month just to address a basic repair, leaving my apartment feeling like a sauna. To make matters worse, they managed to cause property damage during the process and completely failed to notify Irvine Company about it, leaving tenants completely in the dark and dealing with the aftermath. Don't let the suspiciously glowing reviews fool you-the actual customer experience is an absolute nightmare. Zero accountability, terrible communication, and completely unacceptable service. Avoid at all costs.

Lane and his team are amazing. Always quick to answer and schedule right away. None of my residents have issues when they service an occupied unit. They are very professional and respectful. If you need your HVAC system serviced you can always count on them.

Ive been using Aquinas for about 4 years now and have nothing but positive experiences with them. They have replaced over 30 full HVAC systems at my property and are very responsive when it comes to scheduling. If something goes wrong on a unit that requires a manufacture warranty they can normally get it taken care with 24-48 hours. Lane and James are very professional and knowledgeable and seem to always be available for any questions I might have. I would definitely recommend Aquinas for any of your HVAC needs.

I highly recommend this business, their customer service is second to none. I am the service manager for a 756 unit apartment complex and started using Aquinas over the summer. They have replaced over 7 new HVAC systems and completed multiple service calls with no issues. The install quality is consistently outstanding, exceeding my expectations every time. Lane and James are great! They communicate well and I was completely impressed with their professionalism and customer service. They follow through with everything and constantly keep you updated with any changes.
