HVAC reviews in Brooklyn, New York

Dave's work is flawless - he'll stop at nothing to ensure perfection. If you don't take my word for it, call him yourself and see the dedication he brings to every task.

I had a problem with my cooling system that required replacing an old thermostat. This company is top-notch - they're prompt, attentive to customer needs, and get the job done quickly. They arrived on a Sunday when everyone else was closed, which impressed me. The repair and installation were flawless. I'm extremely satisfied with their service.

I've used this service five times at my house, and I'm consistently impressed. Dave is a top-notch technician who takes the time to explain all the options before starting work. The pricing is transparent with no surprises. If you're looking for reliable work on your heating or ventilation system, these guys are the ones to call.

Dave installed the heating three months ago, and the work was top-notch. He took his time explaining how it all worked before leaving, making sure everything was in order. He even made a couple of follow-up calls to check on things. When I had an issue with the system recently, I called him and he arrived promptly. His professionalism saved me from a potentially disastrous situation - the temperature dropped below 20 degrees! That's why I'd highly recommend Dave to anyone without hesitation.

Dave fixed our office's heating issue in 15 minutes. He identified the problem and restored heat promptly. For my home, he arrived on schedule, explained what was wrong, and quickly got it working at full capacity. His professionalism and expertise are top-notch; I'd definitely hire him again without hesitation.

Dave saved the day once again. A midnight power outage left me stumped since none of my circuit breakers had tripped. He sprang into action without hesitation, arriving promptly to diagnose the issue. His expertise got the job done quickly and restored power. I'm extremely grateful for his prompt response, especially in an emergency situation. What impressed me most was that this wasn't a typical HVAC-related call - it showed Dave's reliability and dependability in unexpected situations.

I'm extremely satisfied with my experience with Allegiant Mechanical Contracting, thanks to Dave's exceptional service. As a laundromat owner struggling to find reliable technicians for my specialty water heaters, I was blown away by his prompt response. He arrived the next day as promised and worked efficiently. After the initial repair, he kept in touch, even when issues persisted, collaborating with the manufacturer to resolve them. Dave's professionalism, communication, and reliability made him a standout – I wholeheartedly endorse him!

My experience with Allegiant Mechanical was disappointing. I had high hopes for a reliable and skilled HVAC technician, but unfortunately, that didn't materialize. When I had my unit evaluated, Dave made some commitments about sending over a proposal within a day, which never happened. After following up, he promised it would be done in just a few days, only to stop responding after that.

The lack of follow-through and communication was frustrating. Despite my initial positive impression of Dave, his unprofessional behavior turned me off. Unfortunately, I wouldn't recommend Allegiant Mechanical based on my experience with him.

Price was fair. Tech was very professional.

Very pleased.

Friendly and professional staff provided excellent service from scheduling to installation. Highly knowledgeable and courteous throughout the process. Would definitely recommend them to anyone.

This business is super efficient and really helpful from start to finish. They got the job done quickly with minimal hassle.

Avoided using this company after they failed to follow through on their commitments. I paid upfront but was left in the dark, only to discover someone else had used the service at the same address.

The technicians arrived promptly for the emergency visit and presented themselves in a highly competent manner, resolving the heating problem efficiently.

The plumber fixed my boiler properly. I had issues with it being disconnected at home. I called the company and they did a great job. Highly recommend them to others.

Troy diagnosed the issue with our heating system and made it work flawlessly. He's reliable and would definitely be my next choice for repairs.

T&T delivers top-notch service with reasonable rates. They complete jobs efficiently and produce high-quality results. Their staff is friendly and professional.

Found this company online and had them come out within a short time frame. The technician was super professional, knew his stuff, and got the job done fast - no fuss or delay.

T & T Heating & Cooling got the job done after Sandy destroyed my place - new furnace and boiler installed quickly. They're solid, reliable, and do what they say they'll do.

Had a quick issue with my boiler but Troy's team fixed it in under 20 minutes. The work was done efficiently and now everything is functioning smoothly again. Thanks to T&T Heating and Cooling, I'm no longer worried about the cold - it's working perfectly for me and my family.
