I don't normally write reviews but needed to write this one. Josh came to our house on an emergency call and fixed our problem right away. We had him back a week later to clean our central air. We are so happy to have found him and will be having him back in September to clean and service our gas furnace. Josh is extremely knowledgeable and goes beyond what he was called to do. We highly recommend him!

Josh was knowledgeable, went up and beyond with his service, was easy to talk to, and took his time to make sure that EVERYTHING worked right before he left. All for one flat price. He is now my new service company.

Josh was great. He immediately got in touch with me after I sent in a service request. He made me a priority even on a weekend. I had tried other companies before coming across Hyson Mechanical. My Thermostat completely died on me. Josh comes fully prepared and stocked he even had replacement parts. I highly recommend Hyson Mechanical.

Joshua was amazing. He is very knowledgeable and does high-quality work at a fair price. He responded immediately when I was having a heating issue on a couple of the coldest days of the year. He was able to get me up and running faster than I thought possible.

Josh was very professional, on time & found the root of the problem with our central AC system. He also was very communicative which I find Is hard to get within this industry of work. Highly recommend on every level.

Megan Roma

It was great doing business with Josh. He was very responsive and was there to help solve my issue with my HVAC. Very honest and informative. He was able to find replacement parts and make the repair, rather than trying to sell me on an upgrade or unnecessary things. I would definitely recommend Hyson Mechanical.

Chris Higgins

Josh was fanatastic! During a weekend emergency call he was very responsive and helped us to manage the booking in a way that saved us money. He was extremely knowledgeable about our antique furnace and the maintenance/repairs done prior. He explained what happened with our 'sooted up' furnace and performed a thorough servicing and came back asap to replace a part. We will use him again and have been recommending his services.

Catherine Ignagni

My Concord furnace was 20+ years old and wasn't working properly. I called Josh to arrange for a review+check up. Josh diagnosed the issue quickly, made recommendations and provided timely quotes for the labor and mechanical updates. From the choices, I chose to do the Concord furnace replacement and scheduled the install with Josh.

Josh completed the work in one day. The effort required replacing and re-routing lines to the new furnace unit, so it wasn't just a plug-n-play kind of thing. A full operational test with new digital thermostats was performed and evaluated before the effort was declared complete.

Josh is respectful, efficient and competent.
Highly recommend!

Joshua was incredible! Being first time homeowners, he took the time to thoroughly explain everything to us and answer our questions. He is extremely knowledgeable. We will definitely be recommending Hyson Mechanical to all of our family and friends.

Kelsey Linehan

Josh did a great job, knowledgeable, informational and professional. He got me out of a bind with no heat/hot water, highly recommend

Stacey Surette

Very knowledgeable, definitely earned a repeat customer .

Christopher Santiago

I've had Hyson Mechanical service both of my units several times and I can't say enough. The company really looks out for their customers and tries to get the right price for the parts needed. If you're in need of a good HVAC company to help you through the summer and winter months. Look no further.

Antonio Cicolini

I highly recommend Hyson mechanical. They did an amazing job. They showed up on time and explained everything they were doing and outcomes. Great communication. They truly value quality work and professional demeanor.

George Powell

After being told we needed to replace our entire system by a few repair men we had Hyson come out for an estimate. However, after a quick inspection he noticed the problem and got us up and running with a minor fix! Knowing I was mentally prepared to have to replace the system, he could have easily just given me a quote and left. But I appreciate his honestly and thoroughness. We will definitely call him again when needed!

Kim Rairdon

Josh is extremely responsive, professional and reasonable! I highly reccommend Hyson Mechanical for all of your HVAC needs.

Debb Quinn

I had Josh install an LP Gas Pipe Line run through my cellar to rear patio area to service my gas grill. This ends my trek to BJ's to have that 20-pounder filled! Very experienced he has the knowledge and all the tools to make this job go very smoothly! Very meticulous he goes over and above required specifications to make his work stand out! Very impressed with his work ethics do not hesitate to hire Josh for any of your HVAC needs. Attached are some pics interior and exterior of this work. I did have a high quality Sturgis 1/2" natural gas hose that came with my grill that I wanted to use but did not have the matching Female quick disconnect. Not available locally I ordered the Female Sturgis Quick Disconnect and reconfigured exterior connection piping in that last Picture. Thank You, Josh

Rick Deckard

Very professional and responsive. Cost was thousands less than other quotes and the service was completed very quickly. I highly recommend working with Josh and Hyson Mechanical.

Paul Proctor

Prompt, professional and affordable. On the coldest weekend of the year our furnace stopped working. As a first time customer I called, Josh answered and was on site within 45 minutes. He fixed the issue very fast. We will use him again and refer him to all friends and family.

Kizito Paganini

Josh is the absolute best! Not only did he give me a great value but his work was top notch!


I had an emergency with my oil tank, texted Josh and he was at my house in 13 minutes. He and his team worked all day and did far more then a basic service to help me out in a bad situation. This is the second time I've used him for an issue in my "fixer upper" after going through several other businesses who no showed appointments or tried to rip me off. He also takes the time to answer my millions of questions which is invaluable when you're dumping tons of money into an old house. I don't remember how I found him but thank God I did. I won't use anyone else.


This is my second time using Hyson Mechanical, 10/10 HIGHLY recommend. After an SOS text at 6 AM, Josh was out at 9 AM to check on our HVAC system which stopped in the middle of the night. He showed us the problem, and how to self-correct. He spent the time to educate us, and charged us very little.

If you need someone, Hyson is your guy!

Timisha Malone

Excellent service. Very knowledgeable. I will be using this service for heating and cooling needs in the future.

Linda Wolf

We had a boiler leaking at my sons house and got an estimate from a local plumber that I thought was high. We found Josh online and called for a second opinion. He came right out the next day, and the price was $1000 LESS THEN the plumbers estimate. He fixed the issue right away. He was our guardian Angel. I would recommend Josh Hyson 100%. Very professional , knowledgeable and extremely good prices.

Ronda Thompson Middleton

We were in a pickle with our heat system not working. We have a two year old in the house and I'm expecting our second child. With the cold, heat was a priority. Hayson booked us almost the next day! Their prices were almost too fair and a very quick job. Hayson's was polite, officiant and took the time to explain how to perform "quick fixes" ourselves to save us some money.

10/10 recommend (and I can be truly be a tough critic especially pregnant lol!)

Timisha Johnson

The Owner is very responsive and courteous. The price and service level is awesone. Josh is now my go-to for my home A/C and heating maintenance/repair. I highly recommend Hyson!

Peter Rienzo

So, tried five days' worth of dead-end multiple service providers to come out to service my boiler after losing hot water. 5 days! A few came out & could not figure out the issue. Another provider told me I needed a boiler replacement for $2K without even coming & looking at it. Josh came as soon as he could, troubleshooted for a few minutes, identified the issue quickly, ordered what he needed, (new motor & other parts), and got my boiler back up and running. He was very professional, courteous, incredibly knowledgeable and super fairly priced for such urgent attention. He will most definitely be my to-go technician for any HVAC/Mechanical needs. If I could give him 10 stars, I would. I give my unwavering recommendation for this guy; and I am not easy to impress. My family and I thank you for such a pleasant experience in dealing with a very unpleasant situation. A+++++++++++++++

Bob Coutu

Josh was exceptional. He is like a surgeon for your central air. Fixed our issues and system is performing better than ever. I will be using Hyson exclusively from now on.

Richard Labrecque

Got my water heater replaced and up to code. Josh was very professional, knowledgeable, and prompt. He gave me a fair price and didn't waste any time. Highly recommended.
