Gold Medal Service
Gold Medal Service
Plumbing, HVAC, and electrical systems make your house livable. One minor issue with any of these systems can put your home at a standstill. In case you find yourself in this unfortunate situation, know that you can count on Gold Medal Service. For over 24 years, our company has been taking care of the homes of New Jersey residents through our top quality plumbing, HVAC, and electrical services. We are available 24 hours a day, 7 days a week to address even the most mind-boggling issues of your in-home equipment. From repairs, installations, and upgrades, our technicians are known for getting the job done right every time. We also provide upfront pricing with a full description of the service before commencing work to avoid any surprises down the line.
"If I could, I would give this horrible service provider a 0.0! I scheduled a plumbing appointment on a call, which was confirmed via multiple texts the day prior to the appt. Then had an employee go to the location during the 4 hour window they specified and wait for the plumber. On the day of the appt, 1 hour into the time window someone calls and says, sorry we’re not going to go because we only do residential plumbing. This was a surprise, as it was communicated to them that this was a business when I had set up the appt. So, I decided to speak with a manager. After spending over an hour of being bounced around from one dept to another, asking for a manager, they never connected me to one and their dispatcher had the audacity to say “sorry for your inconvenience, but you’ll just have to find someone else.” WOW! The hoops they make you jump through and the rudeness is not worth the hassle. I would definitely recommend you find a different plumbing pro for your project!"

Premier HVAC Services
When you need help with your heating, ventilation and air conditioning, you don’t want to hear that your technician is stuck in traffic. You won’t hear that excuse from us. We’re based in Brooklyn, at Sheepshead Bay road - in an office, not a phone drop or a postal address. It gives us quick access to many of our customers. But we also have workstations in Staten Island and Long Island. This way, our techs can quickly help you, whether you have an emergency or a routine call. They can rapidly fan out across Manhattan, Queens, Brooklyn and Long Island, ready to install mini-splits and portable AC units, clean chimneys, service residential and commercial HVAC systems, solve your radiant heat problem or get your furnace running more effectively. Our techs are experienced in all sorts of HVAC installation and repair, from heat pump systems and oil furnaces to air conditioner compressors and ac units. How we began As veterans of the industry for more than 10 years, we formed the company in Brooklyn in June 2016 with just one van and one technician. Fortunately, satisfied customers have rewarded us with many referrals and now we have seven vans and 15 people on our team, including office staff. We’re very proud and very grateful for our success. The team leader is Greg. He oversees all three locations and keeps us organized, making sure we respond to calls and we don’t leave until the customer is satisfied. Our techs are experienced, licensed and insured. We can help you, whether you want a new heat pump, a boiler repair, clean air ducts or a commercial HVAC overhaul.
"I called Premier HVAC Services for a routine check-up, and they never showed up. After waiting 3 hours, they rescheduled for a week later without any apologies. Completely unprofessional and unreliable. I wouldn’t trust them with my HVAC needs."

ECI Comfort
ECI Comfort
For 20 years, ECI Comfort has been designing and installing high-efficiency HVAC systems throughout Bucks County and the surrounding areas. Through our work with Unico and Mitsubishi products, we are able to install high-performance, high-velocity systems in a variety of homes, specializing in those that do not or cannot encompass conventional ductwork. We also service and replace all makes and models of HVAC equipment, deliver home heating oil, install generators and perform energy assessments. Additional contact name - Chase Musser. Additional email - [email protected].
"ECI Comfort replaced our heat pump, which included the outside unit, inside air handler, and thermostat/control, in April of 2020. We paid competitive pricing. Our Trane system is still working like new! During our first regular servicing of the unit, the technician, Selinda Killing, found our Air Scrubber (a device to clean the air as it passes through the Air Handler) not working. That item was added to the Air Handler, free of charge, during installation. Today, the Ultra-Violet Bulb, which is the piece that does the actual cleaning in that Air Scrubber, was replaced by technician Mike Slawecki. That is working well, again! Ms Killing, Mr Slawecki, as well as the entire installation crew, in 2020, were totally professional and polite. Our Air Handler is in our attic, with not-easy-access in the master bedroom walk-in closet. The entry to the attic is 18" X 48", and everyone has handled that very small area without issue. Removing the replaced components, as well as, bringing in the new components, through that opening, was not easy. My wife and I have been quite pleased with all ECI has done for us. ECI Comfort is a first-class operation, and we would recommend them for all of your HVAC needs!"
