Here lie the victims of deferred maintenance. 🪦 Happy Halloween from Thomas B. Mansfield Co. 🎃

The good news is that this graveyard is 100% avoidable. A pre-season inspection keeps your equipment, your facility, and your budget out of the ground.

Fire Prevention Week is a good reminder that boiler rooms often become overflow storage, and that creates real risk.

Three quick checks for facility teams this week:

Clearances: Equipment needs open space for safe operation and service access.
Combustibles: Cardboard, rags, and chemicals don't belong near fired equipment.
Inspections: Heating season is starting. Professional inspection catches issues before they become hazards.

Our team helps facilities stay safe, compliant, and ready for winter. Let's get your inspection on the calendar. https://tbmansfield.com/

Behind every reliable boiler system is a team paying attention to the details most people never see. This week, our crew was on-site for a new Cleaver-Brooks install — checking every connection, testing every valve, calibrating the burner. It's precise, deliberate work, and it's the reason facilities avoid downtime, emergency calls, and costly failures. Reliability isn't an accident. It's built in, one detail at a time.

That's the standard behind every project we take on. Installations get tested under real operating conditions before we call it done. Connections get checked twice. Nothing gets signed off until it meets spec. Not because it's required, but because it's the difference between a system that performs and one that fails when you need it most.

Facility managers don't get a second chance when equipment goes down. That's why we treat every install the same way: like the building's uptime depends on it. Because it does.

1963. That's when Thomas Mansfield Sr. decided boiler service should be done right, not just fast, not just cheap, but right. Thomas B. Mansfield Co. has been at the heart of boiler system solutions in Colorado and Wyoming ever since.

Come the 1990s, T. Mansfield Jr. took over, grew the business and planted new roots in Englewood, CO. A second generation, same standard.

Today, John Mansfield leads the company out of Castle Rock, CO, and we're still family-owned. Still taking the 3AM emergency calls. Still showing up when it matters.

And here's what we're most proud of: some of the systems we installed over 50 years ago are still running today. Same buildings. Same trust. Still keeping the heat on.

Three generations in. Still going strong.

Your boiler's summer vacation is almost up. 🏖️

It's had a few quiet months, but fall is coming, and it's about to be back on full duty. Late summer is the smartest time to schedule maintenance, before the first cold snap has every facility manager in town calling at once. A quick inspection now can catch small issues before they become downtime.

Let's get you on the books! Call us at 303-781-7878 or visit tbmansfield.com to schedule your maintenance check today. 📞

Myth: Bigger boiler = better heating. 🚫

Truth: An oversized boiler can actually run less efficiently, cycle more often, and cost more to operate. The right size for your building matters more than the biggest number.
