General Contractor reviews in Forest Hills, New York

I recently had maintenance and troubleshooting done on my mini split system at home, and I couldn’t be more satisfied with the service. Leonel and his team did a wonderful job—not only were they thorough and efficient, but they also took the time to explain everything clearly, which I really appreciated. On top of that, their prices were very competitive. I highly recommend Leonel for anyone in need of reliable and professional HVAC service.

Just had a brand new 42 BTU Tosot unit installed, and I couldn’t be more excited about the energy savings—especially with the way the economy is going these days. Efficiency really matters now more than ever. NYC has always felt like my second home, and knowing my house is now covered and comfortable just confirms that feeling. Huge thanks to the crew at Master Monster Consulting—professional, fast, and solid work all around!

Our old R22 system finally passed away after proudly serving our family for over 20 years—and what a run it had! We decided to upgrade to a new split central system, and the experience was fantastic from start to finish. The installation was done properly, right on schedule, and at a very reasonable price. The team was professional, explained everything clearly, and the customer service was top-notch. Plus, a 10-year warranty included? What a steal! If you’re looking for quality HVAC work, this is the team to call.

We can’t express how life-changing it has been to finally upgrade our business with a brand-new HVAC unit. After struggling for years with an outdated, unreliable system, the difference is night and day. From the very first conversation, Leo and his team brought a level of professionalism and care that’s hard to come by these days.

They took the time to understand our specific needs and walked us through every step of the process—no pressure, just solutions. The new unit not only brought much-needed comfort to our space but also gave us peace of mind knowing our environment is finally efficient and dependable. It’s amazing how something like consistent indoor climate can transform the entire atmosphere for both employees and customers.

Huge thanks to Leo and the Master Monster team for making this upgrade possible—we’re truly grateful and can’t recommend them enough!

There’s nothing like having a good friend in your hometown and having him and his team show up right when one of our fans failed. Lucky? Nahhh, blessed. They called the local supplier and had everything up and running in a snap, keeping all our customers comfortable like always. I can’t thank them enough for their professionalism and the love they put into their work. Special thanks to José and of course to my friend Leo.

There’s nothing like having real peace of mind when you let the pros handle it. Replacing an AC unit in a NYC apartment is a whole adventure by itself. Tight hallways, curious neighbors, and the super disappearing right when you need him. But Leo and his team showed up calm, handled everything without any drama, and got it done like it was nothing. Clean work, fair pricing, and still under what everyone else charges. You feel safe knowing you’ve got the right people on the job.

Excellent experience.

Be cautious when hiring unlicensed contractors.

Leo got it right from the start - he knew exactly what was needed. He delivered on his promise and did the job well. My AC is now working properly, which is a huge relief. Thanks to Leo.

We hired Leo to tackle our thermostat, steam boiler, and radiator issues. He came across as extremely professional from the initial estimate onwards. His team was also super punctual and tidy during the actual job.

Leo takes the time to explain his process, making it easy to grasp what he's doing and why. He clearly knows his stuff and has a genuinely friendly demeanor - you can tell he does top-notch work.

I hired MLSH HVAC L.L.C after my central air stopped working. Unfortunately, it was a frustrating experience. It took three weeks for them to replace the motor, and I ended up paying more than expected. The vent filters weren't replaced, and the condensation pan was installed incorrectly, causing a leak in the roof. To make matters worse, they charged me for replacing an attic fan that wasn't even installed. I paid upfront, which proved to be a costly mistake. Leo from the company didn't follow up with my calls, providing various excuses before eventually ignoring them altogether. Avoid this company at all costs.

I had my window AC serviced recently and the experience was top-notch. The technician arrived promptly, provided fair pricing, and delivered high-quality work consistently. Now that it's been maintained, I'm good to go until next season. Having a reliable contractor with a trustworthy team is hard to beat - I'd definitely recommend them.

Our experience with Leo was extremely satisfying. As part of a larger project in the city, he took the time to inspect our old thermostat despite being busy. His prompt attention turned out to be lifesaving - he quickly replaced worn-out wiring from his vehicle, ensuring our new thermostat would function reliably for years to come. This exceptional service is genuinely impressive and exceeded all expectations.
