Common Questions
What does it mean that you're a 4th-generation plumbing company?
It means our family has been serving Northern New Jersey homes for nearly a century. This depth of experience translates into a practical understanding of local homes, from classic Rutherford properties to modern builds. We've seen and solved almost every plumbing and heating challenge, allowing us to provide reliable, time-tested solutions and honest advice you can trust.
My heat pump isn't heating properly. What's a common issue you see in Rutherford homes?
A frequent problem we address is a faulty reversing valve, which is essential for your heat pump to switch between heating and cooling modes. Another local issue is corrosion on the outdoor condenser coil, often accelerated by our seasonal weather and environmental factors. Our licensed HVAC technicians can diagnose these specific problems, perform precise repairs, and offer maintenance to protect your system's efficiency.
Do you offer preventative maintenance for water heaters and HVAC systems?
Yes, absolutely. We strongly recommend regular maintenance for both water heaters and HVAC systems. For water heaters, this includes inspecting the anode rod and pressure relief valve. For HVAC systems, it involves cleaning coils, checking refrigerant levels, and ensuring all components are functioning correctly. This proactive service, performed by our licensed team, helps extend the life of your equipment, improve energy efficiency, and reduce the likelihood of sudden, costly breakdowns.
