ATC did an amazing job getting my furnace up and running on a same day call when it was very cold outside and my heater wasnt working. They were very responsive, professional and courteous. Great job, 10 out 10 I highly recommend!!
ATC Mechanical did an excellent job installing my new heat pump. I had the compressor location changed from one end of the house to the other and Stiliyan made sure I was getting what I wanted. His bid for the installation was very reasonable and there were no hidden costs. His crew was very careful, all floors they used were protected and they did a good job of cleaning up after. DEFINITELY A 5 STAR JOB.
I was honestly dreading having to get my ducts and vents cleaned. I imagined dust and dirt flying around everywhere and that I’d be left cleaning up after. Thankfully, that wasn’t the case at all! Stilyan and the team from ATC Mechanical took care of everything quickly and left my home spotless—no extra cleaning needed on my part. Stilyan was professional, efficient, and very detail‑oriented. He explained the process, worked carefully, and made sure everything was done right. The whole job was completed faster than I expected, and my air feels so much fresher already. If you’re hesitant about duct and vent cleaning because you’re worried about the mess, don’t be. With Stilyan and ATC Mechanical, it’s truly stress‑free. I couldn’t be happier with the service and highly recommend them!
ATC Mechanical and Stiliyan did a great job. They came on-site for an initial consultation and provided a very competitive quote, which we truly appreciated! Many other companies refused to assist us because our old HVAC system was quite old and unique, so their prompt response was impressive. They provided all the necessary documentation to us and our HOA in a timely manner, and the installation process was smooth and efficient. The entire team was professional and responsive throughout the entire experience. We highly recommend them!
Exceptional Service from Stiliyan at ATC Mechanical. Exceptional Service from Stiliyan at ATC Mechanical. Stiliyan helped us out in a pinch when we needed a thorough, professional HVAC inspection for a home we’re in the process of buying. He immediately understood the urgency of our situation and went above and beyond to accommodate our tight escrow timeline. Not only did he show up on time and keep me informed about his arrival, but he was also incredibly thorough in his inspection. He took the time to explain and show me the necessary updates and repairs needed to bring the system up to code. Beyond that, he provided valuable advice on efficient ways to plan for future upgrades and gave me a great overview of different HVAC system options. He even offered a rough cost estimate to help me budget accordingly. If you want to support a family-owned business and are in need of an honest, knowledgeable, and detail-oriented HVAC professional, I highly recommend him. I feel very lucky to have found Stiliyan and am looking forward to hiring him as soon as we close escrow.
