NARTA HVAC

Ventilation & ductwork engineering

Smart Airflow Design Built Around Real CFM and Building Layout

We install and upgrade ventilation and duct systems for residential and commercial properties. All solutions are developed for each specific space, taking into account layout, airflow requirements, and real operating conditions.

Every system starts with airflow logic — not guesswork. On-site layouts and measurements are used to accurately calculate duct sizes, CFM distribution, and equipment placement before installation begins.

    After trying to connect with 3 other HVAC companies unsuccessfully, I am so glad we found Natra HVAC. Extremely responsive and polite - the service was exceptional. The team took care to clean and properly vent 2 units which were new but installed incorrectly. They were also very careful with our furniture and everything was put back exactly as it was. Fantastic team - we had a great experience with their company.

    saying good things about this company. Called so many other people which was really disappointing. They really stepped up and answered questions and service was impeccable. They’re gonna be definitely on the short list of valuable companies here in the city.

    They did a great job cleaning my very gross window unit AC. They were very polite, efficient and cleaned up after themselves, plus provided lots of documentation of the process. It was very easy to book and pay as well.

    I hired NARTA to clean my AC wall units and dryer. They went above and beyond to help me fix an additional issue with my thermostat, and were professional, efficient, and most importantly, did an excellent job! I will certainly be calling them again.

    Typical of older brownstones: plenty of heat downstairs, not so much up above. NARTA came and reconfigured the ducts coming out of the furnace to get better balance and airflow to all rooms, not just the lucky few. Really happy with their service and professionalism.

    Fantastic experience, I was really intimidated to call anyone for an AC window unit cleaning that I had been procrastinating on for years, and it was also hard to find someone who does window unit cleaning specifically, at least with online Google searches. I'm so glad I took the chance and called Narta HVAC. They were communicative, clear and honest with their pricing, and went above and beyond by coming early and doing extra unplanned work of replacing 2 other AC units and even taking the old ones so I didn't have to deal with them. Pricing was more than reasonable, and I couldn't be happier with their work. I will be calling them again for my AC maintenance needs. My procrastinating days are over!

    Excellent service from start to finish. The technicians were professional, punctual, and very thorough in cleaning our air conditioning system. They explained everything clearly, worked efficiently, and left the area spotless. The AC is running noticeably better and the air feels cleaner. I highly recommend their service to anyone looking for a reliable and honest AC cleaning company.

    The NARTA HVAC team was incredibly helpful with a small project to clean two of my window AC units. They responded within the hour to my inquiry and confirmed an appointment within one business day. They were on time and very easy to work with. They disassembled, cleaned, and reassembled my window units, showing me photos of the inside of the units. It was a seamless experience and will be back for future needs.

    I called NARTA HVAC to clean my two window A/C units. The team was very polite, professional, and careful throughout the entire process. They did a great job cleaning the units and even cleaned up all the dirt and debris afterward on my balcony. Thank you for such great service and respectful attitude. Highly recommend!

    Very impressed with the guys. They replaced a faulty capacitor and cleaned the condenser coil, bringing our AC back to like-new performance. What could have turned into a full system replacement was resolved quickly and at a very fair price. Highly recommend.

    Very professional, honest and clearly knowledgeable in what they do. Communication was also great. They did a thorough diagnostic of over units and mini split system, we also did a deep cleaning of our a/c wall mount units. They are now very clean and work great! Will definitely use NARTA again!

    I don’t really understand much about AC systems, but they explained everything in a simple way and made me feel comfortable. They checked both of my systems before the summer and found an issue in one of them, which they fixed. Everything is working great now. Thank you for the good work! I definitely recommend NARTA HVAC.

    One of my window AC units stop cooling good. They are pretty old so I was thinking maybe I need to replace them, but I am not ready for that now. I called NARTA HVAC and they come to check. They just cleaned the units and now everything works again like before. I didn’t know cleaning can make such big difference. Thank you for helping me, I will call them again if I need.

    The heating in our restaurant stopped working. I called on Friday evening, and the next day the team came out and took a look at the system. They ran a full diagnostic, found a small issue and fixed it pretty quickly. They also gave some helpful recommendations on how to avoid this problem in the future. What I liked most is that NARTA HVAC focused on finding the exact cause of the problem instead of trying to replace everything. That actually saved me money. I'm planning to replace the whole system soon and will definitely work with them again.
