One down, 45 more to go! 💪

Today I’m cleaning out the dual-temperature loop strainers with each strainer feeding an individual riser serving the dorm rooms.

A lot of strainers to work through, but keeping these systems clean and flowing properly is a big part of maintaining reliable heating and cooling throughout the building.

Your Lochinvar Boiler Specialists 🔥

From brand-new installations to annual service and emergency repairs — we’ve got you covered.

Here’s a full tear-down and deep-dive cleaning on a pair of Lochinvar boilers. We completely disassembled the units to thoroughly clean the heat exchangers, burners, condensate system, and combustion components.

Why go this far?
Because proper maintenance means:
• Higher efficiency
• Lower fuel costs
• Fewer breakdowns
• Longer equipment life

These high-efficiency boilers need more than a quick vacuum — they require detailed, professional service to keep them running at peak performance.

If you have a Lochinvar boiler that hasn’t had a full service, now’s the time. Let’s keep it running strong for years to come.

completed a new Aprilaire whole-home humidifier installation 💧

When the heat is running all winter, indoor air becomes extremely dry — which can cause dry skin, sinus irritation, coughing, and even damage to wood floors and furniture.

Installing a whole-home humidifier helps maintain balanced moisture levels throughout the entire house, improving air quality and overall comfort.

Better humidity means:
• Healthier air
• Easier breathing
• Improved sleep
• Less static and dryness

If your home feels dry during the heating season, a humidifier can make a big difference. Message us for more information or a free estimate.

🔥 Oil Burner Service is VITAL 🔥

If you heat your home with oil, annual maintenance isn’t optional — it’s essential.

A properly serviced oil burner will:
✔️ Run more efficiently
✔️ Save you money on fuel
✔️ Prevent unexpected no-heat calls
✔️ Extend the life of your boiler or furnace
✔️ Reduce carbon buildup and dangerous exhaust issues

Over time, oil burners collect soot, carbon, and debris that can drastically reduce efficiency and lead to costly breakdowns. A simple annual cleaning and combustion test can make all the difference.

Don’t wait until the middle of winter when it’s 10° outside and your system won’t fire.

📞 Schedule your oil burner service now and stay ahead of the cold.

We recently checked the 2-inch sock filter in one of the buildings we manage—and it was already clogged after just 1 month! 😳🛠️

What’s a sock filter? 🧦💦
It traps sediment, rust, and debris before it reaches your pipes. Without regular maintenance, a clogged filter can:
⚠️ Reduce water flow
⚠️ Affect water quality
⚠️ Cause plumbing issues 💧🚰

Regular checks keep water clean, fresh, and safe for all residents! 🏢💙🙌
