“I am a Senior Widow. On Thursday, my furnace shut completely down and was blowing only cold air! Outside the temperatures were in the 20s and it was frigid inside.
I found PRECISION HVAC through Google, and it was truly a blessing! They came out that afternoon and ran some tests.
At first, they thought they could make some temporary adjustments, till I decided if I wanted a new furnace, but as we continue to have conversation, the Carbon Monoxide Meter showed that carbon monoxide was leaking from my old unit, at a rapid pace! They were forced to shut the whole unit down!

They contacted their estimator, Peter, who came later that evening to discuss a new furnace and various prices. On his way to seeing me, he stopped at the office and brought two Space Heaters, for me to use for that evening and Saturday the next day, until the new installers could get to me at noon.
I was truly touched by the fact that Peter would think of my well-being, and bring space heaters on his own!

I am enjoying my new Trane Furnace, and have already referred a new client to them, and have told our manager of the condo complex about their efficiency, professionalism, and reasonable prices. Needless to say. I HIGHLY RECOMMEND PRECISION HVAC … 5 STARS ‼️“

I give the owner big props in helping me out even though Im sure he’s a very busy guy.“

“Bloomingdale HVAC installed my new AC and Furnace. It was a great experience. Competitive price. Peter Wakley was very helpful during estimate, explained everything, answered all questions, even supervised the day of installation. Installation team lead by Angel. Assisted by Nick and Jordan. Whole crew was amazing. They focused on every single details and concerns. Very Happy with their work. Highly recommend.“

“Our furnace went out in one of the coldest days of the year. We called our usual HVAC company we’ve used and no response. My husband called and texted I also called and texted. And till this day we have not received a callback. I called Kings Heating and Cooling they responded quickly and a technician was sent out within 20 minutes. Cole was polite and honest with us. He set us up with a sales rep. Who also came out the same night. Jordan was very personable, funny and he loved our dog Ozzie. We were given space heaters and our furnace was installed within 2 days. Technicians were also professional and respectful. We are very happy with our furnace and humidifier. Needless to say our old HVAC company is no longer on our contact list. A huge thank you to TJ you are awesome.“

“Great experience with Allegiance. The owners were out of town on vacation. They took our call without hesitation got a tech headed our way and got our house back heating within the hour in below 0 temps. Great company and great service. Highly recommend!!“

“I hired Assured for some AC work after my system wouldn't turn on this summer. I have a fairly complicated 2 zone SpacePak system and after getting multiple bids and talking extensively with each contractor, selected them for their low price (considering I needed a complete replacement due to refrigerant regulations), as well as their thorough explanations of the work and responsiveness. Assured was professional, on time, clean, and explained the work as well as care and maintenance so I understood what they were doing and confident how to maintain the system for the future. I highly recommend them.“

“Friendly, professional, informative and efficient, Joe/ Joel was spot on with his expertise. We will consider the other companies’ services when needed.“

“Alex from WAN-Tuck . Heating was able to turn my heat on after TWO - other heater companies could not …..I had my aquastat replaced by the second contractor that came to my home . However my heat still kept shutting on and off and eventually it didn’t turn on and my PSI was all over 50 / 60 / 70 The second contractor admitted he did not know what was wrong with my boiler…. That’s when I had to call. Wan-Tuk as they were the ones that installed it in 2008 Never had any issues till now 2025 I have never maintained my boiler ….. I never flushed expansion tank never did anything. I bleed my heaters here and there……. That should’ve been a clue to me of the quality of the work that WAN - Tuck provides since 2008 no issues / no maintenance till now …………As far as the second contractor that replaced the aquastat disrupted my PSI and did not know how to fix it … before new part was installed my PSI was between 15 and 16………… Alex from WAN-Tuck adjusted the temperature on the aquastat which was set above what it should be set for my boiler (the second contractor missed this detail) ….. Alex got my heat turned …… And my heat stayed on and didn’t shut off anymore….Alex tried to flush my expansion ( to regulate PSI ) but tank valve wouldn’t budge so I had to have it replaced ….. I still have my heat …… Thank you Alex from WAN -Tuk for being Courteous / polite and knowledgeable…..and for taking your shoes off before coming in my house / a lot of heating people won’t even ask…. The moral of my story is, I tried to shop around to save money, but in the long run, I spent more if I would’ve just reached out to Wan -Tuck in the beginning I would not have spent as much as I did on the first and the second contractors ….. in the end, Alex…. Diagnose and repairs were cheaper than the first two contractors and with good results heat stayed on my PSI went down to 20 after expansion tank was emptied and refilled …….“

“Very satisfied with the total experience and the technicians that came to the house .“

“We had such a great experience with Marek! He was so kind, professional, and made the whole process stress-free. He explained everything clearly, fixed our AC quickly, and made sure everything was working perfectly before he left. On top of that, he was genuinely sweet and respectful, which made the experience even better. It’s not easy to find people who are both skilled and caring, but he was exactly that. Highly recommend!“

“Jacob Anderson the general manager really went above and beyond to explain everything to me about the new HVAC system being installed by my mothers house. Very trustworthy and reputable company. Upholding warranties and very competitive pricing.“

“Today I had the pleasure of having my dryer serviced by Yousef. He did and excellent job and I have a working dryer. This company came as a 2nd opinion from AHS. the 1st company was a total disaster. The took pictures but never opened my dryer as Yousef did to diagnose the problem. Thank you yousef for your knowledge and expertise in fixing my dryer“
