Five days ago, I had the maintenance service for my HVAC system done by Dennis. He did an…read moreoutstanding job as usual. It is always a pleasure to have our system serviced by him. He is always pleasant, professional and very polite. He made sure to ask if we have had any issues with our system since the last service, and whether or not they were addressed to our satisfaction. Dennis is very thorough.He checked to make sure that everything was working properly before he left, and asked if we had any questions or concerns. When he left, I felt really confident that the best job had been done, because it was obvious to me that he was genuinely concerned in doing a good job. I am giving him five stars without any hesitation whatsoever.

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.

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

My call was answered by Cheryl (I believe that was her name...if not I apologize in advance). She was so courteous and helpful. Instead of taking my name and telling me someone will call me back. She actually took the time to walk me through some of the common problems so that I can troubleshoot. Once we figured out that the issue will need professional help she got me on the calendar as soon as possible. I was scheduled with Lou A. He was super communicative prior to the appointment. Once here, he quickly diagnosed that the problem was the capacitor and got the ac working in no time. Despite having a jammed schedule he did not make me feel rushed and answered all my questions. Their fees were fair and not one of those big companies where they will nickel and dime you for every little thing they do. I've used several hvac companies in the past and this has been the best experience thus far. We will look to use these guys for future issues.

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.

He explained exactly what was done and what still needed to be done very clearly and was very accomodating. Both heating systems are working much better now and I would recommend Charlie to anyone in our area of NJ.
