I had an extremely disappointing and unsatisfactory experience with Inventi Service. Their…read moretechnician, Yuriy, came to my residence on Oct. 5, 2026, to perform a diagnostic and tune up on my heating system and a diagnostic on my AC system which was not working. Upon his arrival, Yuriy stated that Inventi Service did not work on electrical heating systems and, so, he refused to perform a diagnostic on mine. Then, because he was not able to figure out how to power on my AC system, he did not perform a diagnostic on that either. Despite this, he then had the nerve to bill me for those services that he had not performed! When I reported all this to Andrei, the owner of Inventi Services, much to his credit, he immediately apologized and asked what he could do to "make things right." When I replied that he should refund the payment I had made, he did so immediately and for that I am most appreciative.

Part was covered under warranty however labor was not. We was quoted a price for the labor. Said go ahead what the hell just fix it. So a few minutes later and $200.00 + for labor costs the job was completed. By the way the part was $20.00 on line. I should have remember that a few years back I helped a neighbor replace the same part on his AC unit. Job took all of 5 minutes. Wish I would have remembered this, my own fault. App. $50.00 or so for labor costs yes but $200.00 plus is a bit steep.

From the moment I reached out for a quote, Oscar was incredibly responsive, transparent, and honest about his availability and what to expect. He took the time to explain the options, answered all my questions thoroughly, and never tried to upsell or pressure me into anything. It's rare to come across that level of integrity and clear communication in the home services industry. Even though we couldn't move forward this time, I wouldn't hesitate to recommend Whitestone to anyone looking for reliable, trustworthy HVAC services. Looking forward to using this company in the future!

When we met the crew; Sam, Sal, and Erick, we knew we had chosen the right people. They are meticulous in all their work, and most importantly when there are complications for joining the systems they take the time to craft the best solution, no matter what extra work that entails. Even more than that, they are the finest people you want to know, taking care to make your job their priority. You can't do any better!

I recently purchased a new Carrier HVAC system for my house from Princeton Air. Unfortunately, I am…read moreextremely dissatisfied with the installation after spending $26,000 for a new system. The first system they installed was the wrong size. I had to wait almost a week before they reinstalled the correct size system. Much to my dismay, the second system isn't working either. I called into customer service and asked to speak with a manager, I was told there was no manager to speak with. The customer service representative said another repairman would be out this evening. Waiting on that repairman now in my very cold house. I am now a completely dissatisfied long term customer that regrets going with Princeton Air. I will update this post when/if they correct the problem AND I have had an opportunity to speak with a manager. Update 12/15 - Happy to say PA has my new HVAC system working now. I spoke with a manager this morning and he went out of his way to make things right. Update 1/16 - two repairman were out twice yesterday. The first one said it was the thermostat was faulty. That was the third thermostat they put in. Heat was working when he left only to quit working a few hours later. Another repairman came out later in the evening and said the problem was the filter. Evidently it was too big for the system. So he changed the filter to a smaller size. It's working again, for now. Unfortunately, I have lost confidence with this company after having used them for years. Their quality seems to have gone out the window after recently having merged with Weltman Home Services. Think twice before you use Princeton Air!!! Update 1/31 We woke up this morning to a cold house. The thermostat said 65 degrees. When we turn up the thermostat the unit seems like is shutting down. Called customer service and they said someone would be out today. They couldn't give me a time or even a window as to when they will arrive. I am beyond fed up with Princeton Air. My next step is to get an attorney to see what I can do legally.
