Frequently Asked Questions

My boiler in Islip Terrace keeps breaking down or short-cycling. What does Carleton Ave typically do to fix this?

Boiler issues like breakdowns and short-cycling are common in our area, often due to age, sediment buildup, or faulty components. We start with a thorough inspection to diagnose the root cause—whether it's a failing thermostat, a blocked heat exchanger, or issues with the circulator pump. Our approach is to provide a lasting repair or, if necessary, recommend a replacement system that's correctly sized for your Islip Terrace home to ensure efficient, reliable heat and prevent future problems.

I need a new water heater installed. Does Carleton Ave handle both traditional tank and tankless models?

Yes, we provide full water heater installation services for both traditional tank-style and on-demand tankless units. Our team will assess your household's hot water needs, space constraints, and fuel source (gas or electric) to help you choose the most efficient and cost-effective option for your home. We handle all aspects of the installation, including proper venting and code-compliant plumbing connections, to ensure safe and reliable operation.

What sets your approach to drain repair apart from other plumbers in the Islip area?

Our philosophy is to find and fix the core problem, not just provide a temporary solution. For drain repairs, we use camera inspection technology to accurately locate blockages or damage within the pipe. This allows us to determine if a simple cleaning, a targeted spot repair, or a section replacement is needed. We avoid unnecessary digging and ensure the repair is built to last, addressing the common issue of recurring clogs that many homeowners face after quick-fix jobs.
