"Used Len the Plumber in Cherry Hill for the first time. Called at 8 a.m. and they had someone out within a couple of hours. Pricing was up front, so no surprises. The tech - Sonny - was great! He answered all of my questions and had the toilet repaired in under an hour. I was concerned that the 30-year-old toilet would need to be replaced but, thankfully, Sonny determined that the toilet was in good working condition. I appreciated the honesty! I would have given 5 stars but pricing seemed high - almost $400 to replace a $20 part."

Horizon Services is the region’s largest and most well respected plumbing, heating and air conditioning company, with nearly 600 employees serving tens of thousands of homeowners throughout Delaware, Southeastern Pennsylvania, Southern New Jersey, and Northeastern Maryland. After a quarter of a century in business, Horizon Services remains fully committed to setting the industry standard for customer service, installation, and focusing on things that are important to busy homeowners: respect for their time, their home and their property; up-front pricing, and an unconditional 100% money back guarantee.

"Stellar service from a company with a well-earned reputation for solid workmanship. These guys are the real deal. Ramon was exceptionally knowledgeable and spent a great deal of time explaining what needed to be done. Once I signed the contract, everything happened at lightening speed. The servicemen showed up on time, were careful to not damage the doors, walls, or hardwood floors when they hauled in the new gas boiler and water heater, and left the basement in spotless condition. After I sold the oil stored in my old oil tank, Horizon was out the very next day to cut up the tank, clean the inside of it, and haul it onto the driveway for inspection. Not a single drop of oil was spilled. They are that meticulous about their work. A shout out not only to the remarkably zenlike Ramon, but also to Robert, who patiently and respectfully dealt with an unnecessarily finicky inspector."

FAQs for tankless water heater installation projects in Mount Laurel, NJ

Professional flushing services for tankless water heaters run about $200 per visit. This essential maintenance procedure eliminates mineral deposits from critical components, particularly the heat exchanger. While homeowners can purchase DIY flushing kits for $50 to $100, professional service offers the advantage of thorough cleaning with proper techniques. Professional maintenance also includes inspection of additional components that might need attention.

Industry experts and manufacturers recommend annual maintenance for tankless water heaters, with more frequent service (every six months) for homes with challenging water conditions. This regular attention prevents efficiency losses and extends the unit's operational lifespan. Watch for warning signs like reduced water temperature, inconsistent performance, or system error codes that might indicate maintenance is needed sooner than scheduled.

Neglecting regular maintenance allows mineral scale to accumulate within your system, restricting water flow and reducing heating efficiency. This forces your unit to work harder, consuming more energy while delivering less satisfactory performance. Over time, this strain can lead to component failures, inconsistent water temperatures, and premature system replacement. Additionally, most manufacturers require documentation of regular maintenance to honor warranty coverage for major components.
