Services Duncan Plumbing and Gas offers

Duncan's core services include plumbing repair and installation, gas line work, and HVAC maintenance and repair. On the plumbing side, this covers leaking pipes, fixture replacement, water heater service, and drain cleaning. Gas line work includes new installations, repairs, and safety inspections. The HVAC division handles furnace and air conditioning repair, maintenance plans, and new system installation.

Many South Carolina homeowners use Duncan for routine maintenance—annual air conditioning tune-ups before summer, furnace checks before winter, or water heater flushing to extend equipment life. Others call when something breaks: a burst pipe, a gas smell, or an air conditioner that stops cooling. The company also works with builders and property managers on new construction and multi-unit projects.

How to contact Duncan and request service

The primary way to reach Duncan Plumbing and Gas is by phone. A dispatcher will ask about your problem, your location, and your availability, then schedule a technician visit. Many contractors also maintain a website where you can request a callback or submit service request details online.

When you call, have ready: your address, a description of the problem, and your preferred appointment window. If you are calling about an emergency—a gas smell, a burst pipe, or no heat in winter—say so immediately. Many plumbing and HVAC companies offer emergency service outside normal business hours, though rates may be higher.

What to expect during a service call

A Duncan technician will arrive at your scheduled time, assess the problem, and explain what they find. They will then provide a written estimate that breaks down the cost of parts and labor. You are under no obligation to proceed; you can get a second opinion or decide to wait. If you approve the estimate, the technician will perform the work and explain what was done before they leave.

For larger jobs—a new water heater, a furnace replacement, or extensive gas line work—the estimate stage is especially important. It gives you time to understand the scope and cost before committing. Some contractors offer financing options for major repairs; ask about this when you receive your estimate.

Service area and availability

Duncan Plumbing and Gas operates within a defined service area in South Carolina. The exact boundaries depend on the company's current capacity and staffing. If you are unsure whether your address falls within their service territory, call and ask; they will tell you directly or refer you to another contractor if they cannot serve your location.

Availability varies by season. Summer and winter are peak times for HVAC calls, so response times may be longer during those periods. Spring and fall typically see shorter wait times for non-emergency service. Emergency calls are usually prioritized regardless of season.

Pricing and payment

Duncan, like most plumbing and HVAC contractors, charges a service call fee to come out and diagnose the problem. This fee is often waived or credited toward the repair if you proceed with the work. Parts and labor are then billed separately based on the estimate you approved.

Payment methods typically include cash, check, credit card, and sometimes financing plans for large jobs. Ask about accepted payment methods and financing when you schedule your call. Some homeowners use their homeowner's insurance or home warranty to cover plumbing or HVAC repairs; if that applies to you, mention it when you call so Duncan can coordinate with your insurance or warranty company.

When to call a plumber versus handling it yourself

Minor issues like a dripping faucet or a clogged drain can sometimes be handled with basic tools and online guidance. However, most plumbing and gas work requires a licensed technician. Gas line work is particularly important—improper installation or repair can create safety hazards. Water heater replacement, new fixture installation, and major pipe repairs also benefit from professional expertise.

If you are unsure whether a problem is DIY-friendly, call Duncan and describe it. They can often tell you over the phone whether you need a technician or whether a simple fix might work. This conversation costs nothing and saves you from making a problem worse.
