Proof We’re the Best HVAC Company Straight From Our Customers

Mini-Split Installation That Exceeded Expectations

Gwen Anderson

Jake is amazing! We reached out to get a quote for a mini-split system to cool our server room, and Jake exceeded our expectations. He recommended a more cost-effective solution that has provided us with incredible results. His out-of-the-box thinking and thoughtfulness are so impressive. I had six other HVAC companies provide quotes, but Jake was the only one who made sustainable and well-considered suggestions. The office staff is also super friendly and helpful!
Came Right on Time for Our

Dominique Haffery

We just had Master Mechanical service our AC units before it gets too hot! This way we know they are operating efficiently! I used to be scared to pay money for these things but it truly saves money in the long run! Master Mechanical was able to come out quickly, give me a shorter window then most companies do in this trade, came right on time, communicated the whole way! They are professional and experts at their craft! Highly recommend!!!
A Great Company for Complicated HVAC Problems

Eric Williams

Jake did an excellent job helping me solve a complex problem that no one else could help with - I needed a new thermostat installed for a unique 120V water chiller AC system, and all other HVAC companies refused to work on it. Jake was on time, friendly, informative, and had it done in less than an hour. Highly recommended!
Saved $1000 With a Second Opinion on AC Repair

Kris

I’m glad I called Master Mechanical for a second opinion. They saved me $1000 over the quote for the same repair from another HVAC company. They were professional on time and fixed my unit same day. They also weren’t pushing upsales. They did let me know my options, but unlike the other company, Master Mechanical didn’t try using scare tactics to get me to buy additional services. Master Mechanical will be my first choice going forward and I’ve already recommended their services to family members as well.
Repaired My Boiler Instead of Pushing an Unnecessary Replacement

Kathleen Ferraro

I am so grateful to Master Mechanical for repairing my old boiler. Danny Chee is very knowledgeable and was able to figure out the problems and repair them. Plus he is a very nice, polite person. He made sure everything was working correctly before leaving, even after 5:00. The people on the phone, Paul and a woman whose name I can't recall, are professional and helpful. I received texts and emails confirming appointments and letting me know when Danny was on his way. They could have sold me a new boiler but instead fixed the old one at a fraction of the cost. I highly recommend them and will continue to rely on them in the future.
