"My a/c circuit breaker kept tripping upon start-up of the unit. I read the positive reviews about KN, so I requested a quote and Kevin responded with a text within an hour. He was even able to come the same day and spent 2 hours to thoroughly inspect and test the various components of the system (including the connector in my attic), and replace the hard start. Kevin was very professional and thoroughly explained how the system functions and what he was doing each step of the way, which I really appreciated. I would highly recommend Kevin for your HVAC needs!"

"We had a phone call and he actually helped me figure out that I might need a plumber instead of HVAC repair. Mark was very courteous and so helpful! If we do end up needing to go back to him I will definitely call for them to make a visit."

"This Company is top notch! They quickly responded to my urgent message in regard to no heat in the house and had the service guy arrive to the door right after completing another job. They were very professional and did the repair in no time and price quoted over the phone was exactly what was charged for the service. We will definitely call this Company again for any boiler repairs. Thank you!"

"The technician and owner showed up on time and got right to work. They cleaned all the vents in the ceilings and walls. Howard and the technician were very friendly and helpful. After they finished the a/c vents, the technician cleaned my dryer vent. My dryer is working much more efficiently now. I just had to run around with the vacuum to clean up the a small amount of dust that had fallen from the vents."

"The assigned technician, John, was on-time, knowledgeable, provided suggestions, and thorough. Oftentimes, people don’t realize how important this service is. If I were you, I would book AC Air Duct cleaning!"

"Thank you Wise Aire for giving us a great heat repair experience! After submitting a request for boiler/heat repair, Keith called me and was very pleasant. He sent Josh their technician who was just as pleasant, knowledgeable, and addressed all of our questions. Josh did a great job, he resolved our issue efficiently and at a reasonable rate. We would recommend Wise Aire, from this first experience we find them to be honest, reliable, and they do good workð"

"TLDR: This is a great plumbing company and Harris is my current go-to trustworthy plumber. I highly recommend you give HG a call for an estimate if you need plumbing work. I really loved all the work, and I'm rather difficult to please. My experience (over last few months in 2024): HG Plumbing installed our new hot SS water storage tank, a new toilet for a 1/2 bath, and a LG steam washer and dryer (GAS) in our new laundry room. Harris also added a new dryer exhaust vent to bring us up to code, which was quite tricky due to the how the old (incorrect) vent was run, and he came up with a great customized solution for us, which none of the other three plumbers I met with suggested. 10/10 on ALL the work. Harris and his team was on time, easy to communicate with (text/phone/email--he responds to everything!), PROFESSIONAL, and cleaned up nicely after themselves. Plumbing on the North Shore feels very expensive and HG prices are actually reasonable for the area, especially considering the excellent quality of the services. Invoices are up front and clear and Harris is extremely knowledgable, personable and easy to talk to (answered all my questions and concerns--and had many). We discussed whole house water filtration and few other upgrades done the line, and Harris is an amazing resource on all things plumbing and local/code issues. For those with MCS or healthy home concerns: I have sensitivities to many home improvement odors/chemicals and Harris was very understanding and respectful of this. Even the caulk he used was low VOC and finished off gassing extremely quickly. Normally I take 3-4 estimates before committing for non-emergency/maintenance work, but from now on I'm just calling HG. Done right is everything in plumbing and much more cost effective in the long run."
