As we move into the shoulder seasons in Colorado, your building can take advantage of free cooling from outside air — but only if your economizers are working properly.

🔍 Why check them now?
-Economizers regulate how much outside air is brought in for cooling.
-When tuned correctly, they cut down on mechanical cooling costs.
-A stuck damper, failed sensor, or miscalibrated control can quietly drive up energy bills.
✅ Economizer Checkpoints for Fall:
-Verify damper operation and linkages
-Test enthalpy sensors and outside air temperature sensors
-Inspect filters and actuators for smooth movement
-Confirm building automation setpoints
💡 Studies show that malfunctioning economizers can waste 20–40% more energy during shoulder seasons. Regular checks ensure your building takes full advantage of mild weather — lowering operating costs while maintaining comfort.

At Teller Mechanical, we specialize in proactive HVAC maintenance that pays for itself in energy savings.

💡 How Proactive HVAC Maintenance Saves 30% on Operating CostsToo often, building owners wait until something breaks to call for service. The problem? Emergency repairs cost more, cause downtime, and shorten the life of expensive equipment.

👉 A smarter approach is proactive maintenance—keeping systems in a steady, optimized state year-round. Here’s what we’ve seen in the field:🔧 Reduced Breakdowns – Identifying issues early prevents costly mid-season emergencies.⚡ Lower Energy Bills – Clean filters, tuned burners, and optimized controls reduce wasted energy.🏭 Extended Equipment Life – Boilers, chillers, and RTUs that are maintained properly run longer before needing replacement.

💰 30% Savings on Operating Costs – Studies and real-world experience show proactive programs reduce overall spend by nearly a third.

At Teller Mechanical, we focus on helping Colorado businesses stabilize HVAC costs, plan ahead, and avoid surprises. By keeping buildings in a steady state, we give owners peace of mind and long-term savings.

If you’re a property manager, hotel engineer, or facility operator—it’s worth asking: Are your systems running steady, or are you waiting for the next breakdown?

As temperatures drop, rooftop units shift from cooling to heating mode—and that transition is when hidden issues can surface. A fall tune-up ensures your RTUs are safe, efficient, and ready to handle the winter workload.
✅ Fall RTU Maintenance Checklist:
1️⃣ Filters – Replace disposable filters and clean washable ones to ensure proper airflow.
2️⃣ Coils – Clean condenser and evaporator coils to maximize efficiency.
3️⃣ Belts & Motors – Inspect for wear, adjust tension, and lubricate bearings as needed.
4️⃣ Burners & Heat Sections – Clean burners, check ignition, and verify gas pressures.
5️⃣ Electrical Connections – Tighten terminals, check contactors, and test safeties.
6️⃣ Refrigerant & Heat Pumps – Verify charge and inspect for leaks; check reversing valve if applicable.
7️⃣ Economizers & Dampers – Inspect operation, seals, and linkages to avoid cold drafts or wasted energy.
8️⃣ Controls & Thermostats – Calibrate for heating season and confirm BAS/BMS communication.
9️⃣ Drain Pans & Lines – Clear debris and ensure proper drainage to avoid freezing issues.
🔟 Cabinet & Roof Area – Inspect insulation, seals, and surrounding area for debris or obstructions.💡 Why it matters: A proactive fall RTU tune-up lowers the risk of mid-winter no-heat calls, improves energy efficiency, and extends the life of your equipment.👉 Teller Mechanical is here to help Colorado businesses get their rooftop units winter-ready. Contact us today to schedule your fall RTU maintenance.

As heating season approaches, pumps and circulators become the heartbeat of your building’s HVAC system. A fall tune-up keeps hot water moving reliably through boilers, coils, and hydronic systems all winter long.
✅ Fall Pump Inspection Checklist:

1️⃣ Visual Inspection – Look for leaks at seals, couplings, and flanges.
2️⃣ Bearings & Lubrication – Grease bearings and check for unusual vibration or noise.
3️⃣ Motor Alignment – Verify proper motor-to-pump shaft alignment to reduce wear.
4️⃣ Belts & Couplings – Inspect for cracks, fraying, or looseness; replace if worn.
5️⃣ Seals & Gaskets – Check for leaks and replace worn components.
6️⃣ Strainers & Screens – Clean strainers to maintain flow and prevent cavitation.
7️⃣ Electrical Connections – Inspect wiring, test overload protection, and tighten lugs.
8️⃣ Flow & Pressure Readings – Record baseline values to spot inefficiencies early.
9️⃣ Vibration & Noise – Monitor for signs of cavitation, misalignment, or bearing failure.
🔟 Variable Frequency Drives (VFDs) – Check programming, cooling fans, and filters for smooth operation.💡 Why it matters: Pumps running at peak performance ensure balanced flow, energy efficiency, and fewer mid-season breakdowns—keeping boilers, chillers, and coils operating as designed.👉 Teller Mechanical offers complete fall pump inspections as part of seasonal HVAC maintenance programs. Contact us today to schedule service and keep your systems flowing strong this winter.

As winter approaches in Colorado, the reliability of your heating system becomes more important than ever. With freezing temperatures, snow, and sharp temperature swings, proactive boiler and building maintenance is the key to avoiding costly breakdowns, energy waste, and tenant discomfort.Here are some essential steps to prepare your building for winter:
1️⃣ Schedule Boiler Inspections
A licensed HVAC technician can check for leaks, faulty controls, and worn parts before the first cold snap.
2️⃣ Perform a Combustion Analysis
Ensure your boiler is burning fuel efficiently—lowering operating costs while improving safety.
3️⃣ Flush & Treat Water Systems
Sediment buildup and poor water chemistry reduce efficiency and damage equipment. Regular treatment extends boiler life.
4️⃣ Check Pumps & Circulators
Your boiler is only as strong as its distribution system. Test pumps, valves, and circulation loops for proper operation.
5️⃣ Test Controls & Safety Systems
Thermostats, building automation systems (BAS), and emergency shutoffs should all be inspected and calibrated.
6️⃣ Inspect Air Handlers & Exhaust
Clear blockages, clean filters, and verify exhaust and intake systems to maintain proper airflow.
7️⃣ Plan Ahead with a Maintenance Contract
Partnering with an experienced HVAC provider ensures routine inspections, priority service, and reduced emergency downtime.

💡 Why it matters: A well-maintained boiler and heating system not only provides comfort but also saves on energy costs, reduces safety risks, and protects your investment in the building.If you’re looking for a trusted partner in Colorado, Teller Mechanical is here to help. We specialize in keeping boilers, rooftop units, and building heating systems at peak performance—so you can focus on running your business, not worrying about the cold.
