"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."

Arctic Air Conditioning is a family run business that has served New Jersey since 1977. We specialize in residential and commercial Air Conditioning, Heating, Humidification, and indoor air quality. Our other services include Plumbing, Electrical, and Garage Doors. Our philosophy is to provide top of the line equipment with the best installation and service available in the industry. We are an award winning Lennox Dealer and Home Depot Service Provider.

"I do not recommend this company. I contacted Arctic Air Conditioning and Plumbing for a simple leak in my toilet and kitchen sink. They charged a $140 diagnostic fee, which I agreed to — assuming it would be applied toward the repair as many other companies do. However, when the technician arrived, he inspected both issues (which were minor and didn’t require any major parts) and then quoted over $1,000 to fix them. This was shocking and completely unreasonable. No repairs were done, but I was still charged the full $140 just for the visit. Their pricing was way out of line compared to other plumbers in the area. The lack of transparency and the inflated quote felt like a bait-and-switch. Be careful before booking — I suggest finding a more honest and reasonably priced plumber."

Tankless water heater installations FAQs

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.
