From the Desk of Matt Shaw, Co-Founder & COO – Your Preventive Maintenance Playbook

Preventive maintenance isn’t a cost—it’s an investment in uptime, efficiency, and peace of mind. At Mechanical Group, we partner with commercial facilities to deliver tailored HVAC and refrigeration maintenance programs designed to reduce emergency calls, extend equipment life, and protect your bottom line.

Our quarterly maintenance protocols are aligned with seasonal demands and equipment cycles. Here’s how we break it down:



🧼 Spring: Coil Cleaning & Cooling Prep

As temperatures rise, dirty condenser and evaporator coils can reduce heat transfer efficiency by up to 30%, causing compressors to work harder and consume more energy.

We perform:
  •  Deep coil cleaning using low-pressure, non-corrosive solutions
  •  Inspection of refrigerant charge, metering devices, and thermostatic expansion valves
  •  Start-up testing on cooling circuits and economizers

This sets the tone for an efficient, low-risk cooling season.



🔥 Fall: Heating System Readiness

Before the first cold snap, we prep your heating systems to ensure reliability when it matters most.

We focus on:
  •  Heat exchanger inspections for cracks or carbon buildup
  •  Flue draft testing and combustion analysis for gas-fired units
  •  Electrical testing on heat strips, sequencers, and ignition components
  •  Check on building pressurization to avoid negative air effects



❄️ Winter: Refrigeration System Focus & Emergency Readiness

Critical for food service, healthcare, and retail environments, refrigeration systems need uninterrupted reliability.

We verify:
  •  Defrost cycle functionality and drain line integrity
  •  Door gasket compression and air intrusion
  •  Suction pressure readings and superheat/subcooling tuning
  •  We also winterize any exposed or idle equipment vulnerable to freeze damage.



🌤️ Summer: Peak Load Monitoring

During high load, we stay proactive with:
  •  Full cooling performance audits
  •  Thermostat calibration and occupancy schedule checks
  •  Airflow measurement (CFM) and duct balancing
  •  Condensate line flushing to avoid overflow disruptions



Why It Matters:

Routine maintenance reduces HVAC-R service calls by up to 40% and increases asset lifespan by 20-30%. But beyond numbers, it protects your operations from avoidable downtime and unexpected expense.

Whether you manage a retail plaza, restaurant, warehouse, or medical facility, our technician-led approach ensures no detail gets missed—and your tenants and customers stay comfortable year-round.

Let’s put a program in place that makes sense for your facility and budget.
