Stay away from this business! My entire cooling and heating system was left in an inoperable state…read more I called for a diagnostic of the air conditioner today because cool air isn't coming from the vents. I was told the diagnostic would cost $149. I asked to be informed of any repairs that had to be done. Technician checked the system and recommended replacing unit. We discussed replacement unit and cost. I was ready to pay deposit. In the next 10 minutes I was told that the model I selected is old and not available. New model costs $1000 more. I asked for a proposal to decide later. Technician told me that the visit costs $396. He said that he fixed air conditioner that was not working. He never told me that he is fixing anything. Through our the visit it looked like he was figuring out the problem. I talked to the owner and we agreed that any repairs that were done will be undone so that I do not have to pay for repairs. Then the technician removed all the wires from the board making both heat and fan unusable. He did not just undo the "repairs", but made entire system unusable including fan and heat which were working before his visit. See the photos to show what was done!

Reply to 2 reactions from Harmonic on my 1 star review…read more 1. A. & K. claimed A. fixed my heater Tuesday; lie. Bad customer service. Harmonic deserves 1 star, but all the starts below 5 are NOT indicated on the Google graphic of the numbers of review stars 1-4: false. 2. I never promised a review pull-down for a discount. My husband & I have better things to do than having an "agenda" as Harmonic accused. My husband was on a business trip. 3. I never called for an emergency repair. I did not switch from repair to cleaning & maintenance. I asked A. if C & M was possible afterward, unaware of 2 more with no heat. Harmonic called me "selfish" for this. 4. Any possibility A. and K. have unconscious biases towards people like me? They accused us of "manipulating" what? To save a few hundred bucks, while we spent in the tens of thousands at Harmonic's better former (aquired) company) you imagined up? 5. How could Harmonic accuse me of lying about my pain. Because I was able to and had to carry my 10 lb dog for a short moment because of her barkin? Why do I even have to explain my chronic severe back pain and mostly failed back surgeries and weak immune system? 6. I had no "agenda," but getting my heate fixed. I am not playing any "game" as accused. I am standing up for myself. 7. K.'s statistics on the number of my Goole reviews are false. 8. A. & K. are the ones who were "aggressive, harsh, unethical, disrespectful, and manipulative." Stop projecting and gaslighting. I wish I would remember to record conversations when I am alone with a person like A. Why did K pull down his absurd replies on Google?

On Saturday May 18th, after 25 dutiful years, our AC finally died, and on the day of our son's high…read moreschool graduation. Needless to say, it put a damper on the festivities. I called 4 different companies, and no one would come out until Monday. Well nobody, except for Ivan, of Precision Air, who came out on Saturday night at 9:00 P.M. I couldn't believe it! Ivan came out and thoroughly walked me through my different options for both a new AC and possibly a new furnace as well. Additionally, he carefully explained the financing terms and explained clearly how to avoid the financing trap and to pay off everything before 25 months to avoid a compounding of all interest. After spending less than 30 minutes with him, I knew he was the man for the job, so I signed the contract and cancelled all the other companies the next day. Since Precision's prices were so fair, I ultimately decided to replace both the AC and furnace. On Monday, such an unbelievably short turnaround, Ivan's guys were able to replace not only my AC, but also my furnace. My husband was at work and I was a little nervous without him being there. However, everything went great! Stevan and Jeremy were both very polite and checked in with my wife throughout the install. They were here for over 7 hours, and completed the job perfectly. We are extremely happy with everything! Getting a new AC and furnace is an extremely stressful experience, but Ivan handled everything perfectly for us. I am 100% satisfied with Ivan and Precision Air and strongly recommend them to everyone. Another bonus for me was being able to support a true local small business, not some big guy with a satellite office in town. Thank you Ivan and Precision Air!!!

When they came for the install, they informed me that the original humidifier was not the best fit. Rather than installing it just to get the job done they paused. They recommended a different option that was actually a lower cost and that they would have to come a different time to install it. This shows their dedication to customer satisfaction and making sure the customer has the best product to address their needs. Highly recommend them.
