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!"

"Worst service I’ve ever have experienced. They wanted to sell me the product, never told me that there was an early termination fee and another penalty for an initial offer they gave me. Had double charges every month, once for the oil they provided (which they never told me they were going to provide before coming. They just came without my knowledge and then I find a high amount bill) and another for an “automatic payment” for 500 that they never could explain. The didn’t even fix this issue and it kept happening every month even after I cancelled the service. Then having to call them is a hastié for the refund of the 500. Stay away of this company"

Len The Plumber Heating & Air, LLC is a leading plumbing and drain company serving New Jersey. Our certified professional plumbers are available same day to assist residential customers in Burlington County and Camden County. Our knowledgeable plumbers have years of experience dealing with a wide variety of plumbing issues including plumbing repairs, drain cleaning, water heaters, well systems, heating systems, sewer, water, and gas lines. We’re open 7 days a week with no extra charge on evenings or weekends!

"Did not go well at all with Len the Plumber was over charged and feel scammed, Len the Plumber, Technician Len Feldman started approx. 12pm until 3pm most of time going over the cost, taking pictures and finding everything possible that needed to be done and presented 10-page contract. Len Feldman (Technican) assessed the problem that was a leaking outside faucet that he explained froze over the winter and needed to be replaced. While water was leaking he did not turn off the inside valve and requested to have water company (Trenton Water Works) come out and turn off water by the main water line. TWW came out several times but could not find the line and sent out a third construction worker to locate the water line. Meantime Len left his personal contact # and promised to return as soon as the main water line was shut off. When Water Works returned on 6/25 could not reach Len, but was able to locate the main water line Len finally called back and said it would be ok he would be able to turn the water off was currently in Mays Landing that is approx. 65 miles away and could not return 6/25 but would be at my home to complete the job 6/26 am. After 9am no call no Len, I called again several times when finally able to reach him at around 9:30am, said he spoke to Supervisor and could not do anything until the main water line was completely shut off. I called Len the Plumber office spoke to Office Manager Cathy#610-616-3377 she said would try to get someone out asap, by later in the afternoon no return call from Cathy. At this point and 2 days later for an emergency it was time to find another Plumber and I cancelled everything at Len the Plumber. The Plumber came out Friday 6/27 completed the entire job within 1 hour, turned off the inside valve connected to the outside leak immediately as well as water to install the same job Len the Plumber contracted to do that, Len said would take at least 6 hours. Main Water Line never had to be touched!!! I am appalled with Len the Plumber that I could trust thru Angi's List with a good reliable repetition. This company had no consideration about leaving me and my family including my 88-year-old handicapped mother without running water for days, all he was concerned about was how much commission he could make off someone in a vulnerable situation."

"we sold our house and the buyers insisted that the chimney was inspected so that they could use it. Their chimney guy gave them a load of bull with a quote of over 12k. We called 1 Hour Chimney, they came out right away and went over the details of the previous quote. Turns out that the previous quote was a load of garbage, and we were able to fix all of the necessary issues for half the price.

"Fixed for fraction of the cost of others, no service fee, and on time! My heater (19 y/o Arcoaire) was not switching on despite a strong signal from the thermostat and the rest of the unit having full power. I was getting a pressure switch malfunction error code, so I called 3 service companies to get estimates. The trashy Goodman guy came out and refused to service it and only offered to replace it $6,000 or Heat+AC for $10,800. Sila said they could fix it for $3,800, or replace Heat+AC for $9,500… THEN… SK showed up the next morning, on time, with plenty of advanced warning, and was clean and respectful. After only 15 min, he had diagnosed the problem and was able to replace the malfunctioning part for less than 10% of the cost (incl. part + labor) of replacing the unit. WHAT!?!? Heater fired up perfectly after being replaced and is working GREAT. DO NOT LET THE BIG COMPANIES HOSE YOU – call SK and get it fixed for a fraction of the cost!"

Heating and Air Conditioning questions, answered by experts

Freon will go in the refrigerant lines near the back of your AC unit. Look for small ports with caps on a thin copper line—the Freon goes into those ports. You are best off hiring a licensed HVAC professional who can complete the job safely and correctly.

Indications of an HVAC problem include inconsistent heating or cooling throughout your home, unpredictable temperature changes, or inadequate air flow from vents. Abnormal sounds such as grinding, banging, or hissing, and unpleasant smells like mustiness or burning are also potential warning signs. A rise in energy costs without an increase in usage may also imply decreased efficiency. An HVAC system that frequently cycles on and off or cannot maintain a stable temperature is malfunctioning.

AC leaks are common, and an HVAC pro can usually fix them. You may be able to resolve some leaks on your own, but a professional HVAC technician should handle most AC leak repair. If left ignored, an AC leak could cause serious damage to your system or leave you with expensive water damage, usually leading to more costly repairs or replacements.

To make the most out of your AC, consider implementing the following best practices: 

  • Choose the right size AC for your home to ensure your unit runs as efficiently as possible.

  • Choose a window with shade, as direct sunlight can cause your AC unit to overheat. 

  • Clean or replace the filter at least every two months. 

  • Inspect the AC’s fan and straighten it if necessary. 

  • Discontinue use immediately if you suspect a malfunction, as running the AC while broken can lead to significant issues. 

  • Turn off (or adjust the temperature) when you leave the house.

The outdoor portions of air conditioners are designed to weather the rain, so you don’t need to worry about it. An awning or roof will help protect them from snow or falling debris, which can do more damage. This is true of both window AC and outdoor units for larger systems.
