Do you know what keeps many heating systems and appliances running safely and efficiently?

This project by Mulco Inc. involved extending an underground residential natural gas service line to support the property’s gas system.

Proper gas line extensions help deliver a safe and reliable fuel supply to equipment such as pool heaters, generators, outdoor kitchens, BBQs and home heating systems.

Our team completed this work with a focus on safety, code compliance, and clean professional workmanship.

Serving Suffolk County since 1976, Mulco Inc. proudly provides expert plumbing, heating, HVAC, and gas piping services.

Do you know what galvanized gas piping is?

Galvanized gas piping is steel pipe coated with zinc to help resist corrosion and provide long-lasting durability. It is commonly used in certain outdoor and utility applications where strength and protection from the elements are important.

This project completed by Mulco Inc. features new galvanized natural gas piping installed to supply two high-capacity pool heaters. In simple terms, these gas lines safely deliver natural gas to the heaters so the pool water can be warmed efficiently and comfortably for the season.

Our team completed this installation with a focus on safety, performance, and clean professional workmanship.

Serving the East End since 1976, Mulco Inc. proudly provides expert plumbing, heating, gas piping, and HVAC services.

Dune Road, you’re officially surrounded! 💥

When you call Mulco Inc. for your seasonal opening, we don’t just send one technician with a toolbox. We send the entire cavalry.

Take a look at our Trucks—that’s not an illusion; it’s a tactical deployment. While those burlap-wrapped plants in the background have been standing guard all winter, our fleet has arrived to finally get down to business.

At Mulco Inc., we treat seasonal openings like a high-priority mission:

❄️ HVAC Special Ops: Ensuring your A/C is ice-cold before the first May heatwave hits.

💧 Advanced Plumbing Tactics: Reactivating pipes and checking water heaters so your first beach shower isn't a "cold water surprise."

🔥 Strategic Heating Command: Inspecting boilers and furnaces for flawless performance.

We’ve been serving the East End since 1976. We don't mess around... except maybe when it comes to having the best-looking fleet on the road. 🚐✨

Get your home or business summer-ready with the team that treats a routine opening with maximum effort.

Most companies handle either HVAC or plumbing. At Mulco Inc., we do both.

This means every copper line, gas pipe, and duct is designed and installed as one integrated system—not pieced together in the field.

When one company handles every step from design to final installation, there is only one standard: ours.

Your AC speaks a language of its own. Is it telling you something is wrong? 🤔 Don't ignore the clues that it’s time for a professional tune-up!

Here are 5 common signs that your system needs maintenance:

Strange Noises: Clanging, rattling, or squealing sounds often mean loose or damaged parts.

Weak Airflow: Your home isn't getting as cold as it should.

Unusual Odors: Musty smells (mold or mildew) or burning smells (electrical issues) are never good.

Frequent Cycles: It turns on and off constantly, which wears out the motor faster.

Rising Energy Bills: An inefficient system uses more power to do the same job.

A quick check by our experts at Mulco Inc. can prevent a costly emergency.
