I was looking to have central air installed and came across Allined Mechanical with very positive ratings. I gave Bill a call and found he was very knowledgeable. He spent plenty of time answering all my questions. In the end I was extremely satisfied with both the price and quality of workmanship.

I had multiple issues which was handled efficiently and in a timely manner. I do plan on calling them going forward for seasonal maintenance.

Bill and Cody were amazing. They came the same day as I called. They diagnosed the problem immediately and called around to get the specialty part the same day. Bill made sure to explain every step and also how to better maintain my system in the future. Cody somehow fit into my condenser coil apparatus (he looked like a jack-in-the-box) to clean it and make it more efficient. Professional, friendly, knowledgeable, honest are just a few words that define these guys. HIGHLY RECOMMEND!

I had multiple companies come out and tell me my boiler needed to be replaced with a 13k price tag. Billy came out and had the boiler fixed in 45 minutes for less than 200 dollars. Couldn’t be more thankful and will only call him in the future!

I had my water heater leak into my home they extended the work day just to come and replace my water heater very good work and clean will recommend to everyone I know

Knowledgeable and efficient

I needed a whole new air conditioning and furnace replacement. Billy gave me a fair and reasonable price. His work was efficient and very neat!! Highly recommend!!!

I have worked with Allined for nearly a decade on multiple properties that get heavy usage because they are rentals. Allined team has always provided the highest quality work that lasts. They are great people that do the highest quality work. I will continue to use them long term, and fully recommend them.

Billy and his crew were AMAZING to deal with! Very impressed with how clean they were with this major job! I would highly recommend them to anyone. Extremely responsive and professional. Greg Bottari (Wading River)

Billy and his team did a great job as always. 10/10 recommend.

Professional. Pride in their work.

Great communication. On time. Very professional and thorough.

He was very professional and did great work

We hired Bill from Allied to do several things in the house. He changed our condenser from our central AC, did some plumbing work, and worked with our heater as well. It was a pleasure doing business with him and his crew. Very reasonable with pricing. And will keep using this company for anything else we need in the future.

The workers were both very professional and knowledgeable and did an outstanding job I am completely satisfied with their work and will not hesitate to use them again

Highly recommend Allined Mechanical! Billy and his team were able to come over and assess our existing central air system pretty much right away. He was super informative, not pushy (which I have dealt with in the past). Replaced our compressor and got our system up and running in no time. Great customer service, we will be using him for all of our hvac needs from now on!!

Very knowledgeable and courteous. Arrived on time ready to work. Neat and clean after each day. Took the time to explain every aspect of the job being done. Explain how to work and maintain the ac. I would definitely recommend aliened to anyone

Bill was amazing! Our boiler was severely leaking water and needed to be replaced immediately. He made the greatest efforts to perform the replacement asap. Bill went above and beyond for us. He was also professional, knowledgeable and friendly. I would definitely recommend his services.

This review is a little late, Billy and the guys are absolutely great. They replaced a very old 4 ton AC unit.

He was great

This company went above and beyond to get the heat back on at our horse farm. Bill kept us informed and was there when he said he would be. They are extremely professional. I liked his company so much, that we hired him to do a complete a/c and heat pump in our recently purchased Sag Harbor house.

Great communication, prompt service, professional and thorough. Bill arrived within 45 minutes after receiving my call. He took the time to diagnose and repair AC unit after other company failed to do so twice. Highly recommend.

Very professional called back right way and was able to get my AC up and going again fast

Bill responded very quickly and fixed my a/c the same day, , followed up with me several times during the night to make sure the a/c was running, also for the next couple of days check in with me to make sure it was working well. I canâ  t say enough about Bill heâ  s a 10 in customer service
