Another upgrade in the books — out with the old, in with a high-efficiency Energy Kinetics system 🔥

With oil prices being what they are today, it just doesn’t make sense to keep running outdated, inefficient equipment. This homeowner made the smart move and upgraded to an Energy Kinetics boiler, cutting fuel consumption and boosting performance at the same time.

These systems are designed to maximize every drop of oil, deliver faster hot water, and keep your home more comfortable — all while saving serious money year after year.

If you’re still running an older oil-fired boiler, now is the time to make the switch. There’s no reason to keep overpaying for heat.

This morning our team was out at St. Patrick’s Church performing a triple boiler service to keep the heating systems running safely and efficiently. The system includes two steam boilers and one hydronic boiler, all of which received a full seasonal service. Each unit was carefully inspected, vacuumed out, and tuned up to remove soot buildup, improve combustion efficiency, and ensure reliable operation for the colder days still ahead.

Proper maintenance on commercial and institutional heating systems like this is critical. Cleaning and tuning boilers not only improves efficiency and fuel usage but also helps extend the life of the equipment and prevents unexpected breakdowns. Proud to help keep a historic Southold church warm and comfortable for its congregation.

Last week we wrapped up a clean Energy Kinetics EK-1 Frontier installation in Kings Park, replacing an outdated oil-fired system with a modern high-efficiency boiler that runs quiet, recovers fast, and integrates domestic hot water for year-round performance. The install included proper near-boiler piping, combustion tuning, and system start-up to ensure the home runs comfortably and efficiently heading into heating season. Another Long Island home upgraded to reliable modern comfort.

Just got back from an incredible visit to the Energy Kinetics factory in New Jersey 🔥 Witnessing the production of these boilers from the ground up was next level — American-made quality, built with precision and pride. From the welds to the wiring, every detail showed why their systems are the most efficient and reliable on the market. Proud to install equipment we believe in and even prouder to see where it all starts.

Nothing better than kicking off a short week with a big job. Out with the old—commercial boiler removal in full swing. When the equipment is massive, the pressure’s high, and the stakes are real, that’s where we thrive. Call M&M Precision Plumbing and Heating Corp. when the job isn’t for amateurs.

When it comes to gas piping—especially underground—cutting corners can be dangerous. This homeowner learned the hard way after discovering a leak in over 100 feet of buried gas line. We had to unearth and completely replace the system to make it safe and code-compliant.

Gas work is not DIY. It requires certified professionals who understand safety, regulations, and long-term reliability. Don’t take risks with your home or family—trust experienced, licensed pros for all your gas piping needs.

A generator is your lifeline during a power outage, but just like any piece of equipment, it needs regular maintenance to stay reliable. Neglecting your generator can lead to costly repairs or total failure when you need it most—especially during storms, blackouts, or freezing temps.

Routine maintenance ensures your generator starts up every time, runs efficiently, and protects the essential systems in your home or business. That means keeping your lights on, your heat running, your sump pump working, and your family or customers safe and comfortable.

Schedule your generator check-up today and avoid surprises when the power goes out. Your peace of mind is worth it.
