I was away on business and not only did Mike and his man come out in a blizzard to get our heat…read moregoing. He did something that was unbelievable to me. He and his man shoveled all the walkways and the driveway so my wife could get her car out in the morning. They did this because they wanted to make sure the repair would work, and after the installation of the part, there was a certain amount of time the system needed to reboot. I repeatedly tried to pay him for all the extra attention and he refused. This is a true pay it forward company. There are few of these type of businesses these days. He limits his client base because it's not about the money it's more of a passion for this guy. I wish you nothing but more success.

Delayed in writing this review. My Boiler was leaking, and I spent 3 months with my add-on…read morehomeowner's insurance. It was a nightmare; they sent five different HVAC or plumbing companies. When I called insurance to find the next step, I was told they have to send it to another company, for some reason. It came to a head at the end of September, and they finally agreed to just pay a base fee for coverage based on the plan. Prior to this, NO MENTION of a cap payout prior! They provided a quote and phone number to do the job from one of the plumbers who came out. It was an LLC. When I searched the phone number, it was linked to a plumber and a driving school! Needless to say, did not go with them. Now, the reason we are here... along came Peace of Mind plumbing. Mike arrived as promised, quoted the job, and provided a date to install, no fuss, no muss. The installation date came, and it was magic. From the delivery of a new boiler, the breakdown, the tow-away of the old unit, and the installation, everything was flawless and clean. The "Peace of Mind" team worked as an artistic swimming team (including music). It was a pleasure to see the teamwork. A shout-out to Mike and his team. Enrique S

They areGrifters stay away! My 5 year old condo furnace…read morebegan to blow cold air. I called Johnston. They sent out a short guy who always wore a jaunty cap..I say always because he came out every year. Every year on the the coldest night the furnace blew cold air...this same short guy came "fiddled about" got it working charged a few hundred bucks ...then left..until the next year, when I woke up in freezing cold air blowing on me. This happened more than ten years...same guy same cap...I was on his route. I was his pigeon he got paid because I was a stooge. I finally got a professional in RAS in Pompton Plains... They replaced the system at thousands of dollars, but that was 5 years ago.. And I've never had a problem since. Johnston should have stopped ripping me off..over the years I spent thousands with them replacing burners, cleaning igniters, etc..that short beanie wearing scammer and his boss should have advised me to replace. Yes, I didn't want to spend thousands on a new system ...but if it was the answer ..TELL ME. Utter SCAM ARTISTS AVOID

I decided to call Johnston air again for same problem, leaking ductless central air …read more They came within two hour window and really did a great job taking unit apart spraying and cleaning out debri which was clogging drain from leaking condensation. Also checked two additional units for freon and accepted $99 coupon and charged for only 1 unit inspection. Very happy with 190$ total and a good job. Will use again. Much better experience then last time.
