"My AC failed and I had limited time to find a good solution, I made a phone call to Relax HVAC based on the online reviews and it was a great decision. Nasser came to check the situation, he gave a very detailed and comprehensive overview of the situation and provided with the options I had. I decided to replace the unit, Nasser went above and beyond to find a unit delivery service but there was nothing available over the weekend so this gentleman went for unit pick up himself and finished the installation within a day from my initial call. Moreover, the provided price was very reasonable.I can't be more happy with the outcome and highly recommend Relax HVAC"

"The installation team of Eric and Dan were professional and diligent at their work. My son was the one to deal with the institution team. He has over 30 years of experience in the appliance business and knew something about what was being done. He told me that the institution team was doing a great job. I'd definitely recommend them to anyone that's in need of their services. Namcy T. French"

"I’m back again to write another stellar review for GAC. Last year they replaced our HVAC system; this year we circled back and had them install a home generator. This was a long and drawn out process due to the various approvals needed from Montgomery County as well as coordination with Washington Gas (which ended up not just being a simple sign off but necessitating an additional, expensive upgrade to the gas line from the street to our home). Nevertheless, GAC did a fantastic job shepherding this process over the 6+ months of waiting on stakeholders, and they were also maximally accommodating to our family’s significant constraints on time and availability (due to health concerns related to a medically fragile family member). A special kudos to Sandy M, GAC’s master electrician, who took it on personally to ensure we were taken care of all throughout this process, going above and beyond with phone calls, text messages, personal visits, etc. on behalf of my family, I want to thank GAC and am giving top marks across the board for this effort which was complex , lengthy, and ultimately successful."

"Adam was so helpful explaining how the ductless heater/ac unit would fit in my sunroom. His three workers were great. Cleaned up the area after they finished, the job was done in about 4 hours. Got three estimates and Weather Masters was the lowest and could install the next day. I also decided to sign a contract for seasonal checkups on my furnace and central air conditioner. I think anyone would feel comfortable hiring them."

"They came and inspected the sump pump. They recommended for it to be replaced. I was okay with it so they replaced it. They completed within half an hour. We then discussed the bill. They agreed to take off $50 because they have an Angie's List coupon that offers $50 off. There was also a coupon for $250 off a system installation for Angie's List members. I told them of this and they said it would only apply for HVAC units and I said to them that they are more than HVAC company, they provide more services than HVAC. They did not specify that its only for HVAC. The technician agreed and said that they're going to have to change that within our website. This was extremely misleading and felt like a bait and switch."

"We returned from vacation on a Saturday night to find out that our A/C system had died on us while we were gone. I put in a quote request with JDL and someone contacted me within about 30 seconds of my request. A tech was able to come out on Sunday to assess the situation. Ire was extremely courteous and professional, explaining everything along the way. One minor problem was that we needed a new motor (which died while Ire was here) and they had to order the part, which he said they would do first thing Monday morning. While they did, it was going to be another day before it arrived. I asked if there was something that could done, but unfortunately they needed to wait for the part to arrive. A bit later, Ire called me back to say that they were going to drive way out of the way to pick up the part and get someone to our house later that day, avoiding both a large overnight shipping fee and another brutally hot night in our house. Isak showed up and was courteous and professional as well. He explained the work and explained that our system was working, however inefficiently. He explained how we could fix the issue, and laid out the costs for us. We had to decline as it was out of our budget, which Isak completely understood. I'm not sure about other reviews, but at no time did I feel pressured into buying a product or doing something unneeded. I really appreciate the work they did, their customer service approach, and their overall knowledge and professionalism. We are likely to hire them back based on this service."

"One of the best contractor experiences we have ever had. Jim called the day before to confirm the appointment. Larry the Plumber was so nice to deal with. He put on she covers to protect my wood floors, worked very neatly and gave us some tips about ongoing maintenance. He did a perfect job. This review us for Petro in central NJ. i was not able to change the company location. We hired them through Amazon."

"Josh and his crew were professional, on time and explained the install throughly. Josh installed a wall charger for my electric vehicle, disconnect shut off switch in the garage, ran cabling from a new 60amp circuit, additional receptacles in the garage I asked for, whole house surge protector, and more. It was a big job! The best part is my kids were still able to distance learn in the bedrooms without interruption of power while install occurred. Josh answered questions I had even after the job was complete over his personal cell phone when I followed up with a call. This makes for great customer service! Iâ ll definitely be using Wenbrooke for more services in the future. Nice work gentlemen!"
