Henry and his guys did fantastic work in our home. Our home was built 5 years ago and we had a problem with the hvac since it was built. No one has been able to fix it. Henry quickly diagnosed the issue and was able to resolve it. His guys were on time, did great work, and cleaned up after themselves. They were all very nice and professional. Highly recommend.

Absolutely great!  look no further, Henry is top shelf he gave us a Competitive cost.

Put Drop clothes throughout our home cleaned up after he was completed with the installation. You would not even know a contractor worked  in your home.

Communication was great. Did the work exactly as proposed from beginning to end, including meeting our time schedule.

He went out of his way and reschedule his team to work on Sunday in order to accommodate us.

Thank you Henry and your team for a wonderful job. You are my Contractor For life.

Best regards, Pat Floria.

Henry at MastAir-Works came highly recommended to me.  From the phone call and conversation to the service call at my house Henry was 100% professional and easy to talk to.   Henry and Anthony arrived on time and was very respectful of our home (covering of their shoes to walk in on a rainy morning)  Henry was informative and explained everything to my husband that was going on with our heating system.  We were absolutely happy with the work performed and will definitely use him in the future for any heating and A/C needs.

This company has serviced my gas furnaces a couple of times, and I have been very satisfied. The staff is knowledgeable, resourceful, and very honest about the nature of the repairs.

I will definitely consider doing bigger projects such as equipment replacement with MastAir-Works.

Needed my Burnham gas boiler diagnosed, as it was having some issues. Henry came over on time, diagnosed the boiler and found the problem.  The part was replaced the next day and everything worked great.  Prices were extremely fair. Henry and his company are now my go to for any of my HVAC needs.

- Jerry Rivera

Easy to work with. Took time to understand my concern and design right solution. Other hvacs I spoke to just offered to do what they usually do, didn't try to adjust to my situation. MastAir actually took time to understand. Work done was expanding an ac zone and installing an energy recovery ventilator. Will use them again.

- Edward Markovich

Henry and his crew did an awesome job installing a mini split unit.  They were processional, on time and pricing was reasonable. He took the time to make sure everything was completed neatly.  They left the place very clean.

- Diane Powell

Henry and team were great! Fixed my issue in no time. Would recommend to all friends and family!

- Konaal Kumar

Being a critical person with nothing to criticize. Now that's frustrating! But that was my experience with Henry and his crew. Impeccable design and installation of a mini split AC system. From drop cloths and booties to protect my house to not finding a spec of construction debris inside or outside. One of my best experiences with a contractor and a perfectly operating AC system, Well done!!

- Mark Syetta

My husband and I highly recommend Mast-Air for good quality of work and prompt response. Henry's workers are knowledgeable and professional. We are a happy and satisfied customer and will hire them again in the future if we need to.

On Sunday 01/26/2025 Henry and Anthony solved my No Heat problem. They were on time, diagnosed the problem and installed a new part. The system was checked out and a clear explanation given to me. I will call Henry again for AC/Heating problems. Suggest you do the same.

- John Woolf

What can I say, my husband and I were very impressed with Henry's work, his time, dedication, honesty, and professionalism, are just outstanding. His prices were reasonable, he was fair, and really made sure everything was to our liking.  Would I use and recommend Henry, absolutely every single time?
