Pre-Summer Commercial HVAC Checklist

Memphis summer doesn’t ease in—it hits fast. And once the heat is here, HVAC problems turn into emergencies overnight.

The difference between a smooth summer and a mid-July breakdown usually comes down to preparation.

Here’s the pre-summer commercial HVAC checklist every Memphis business should follow before temperatures spike.

Inspect and Clean Condenser & Evaporator Coils

Dirty coils are one of the fastest ways to lose cooling capacity.

Pre-summer coil cleaning:

  • Improves heat transfer
  • Reduces energy usage
  • Prevents compressor overheating
  • Extends equipment life

This alone prevents a huge percentage of summer failures.

Replace or Clean Air Filters

Clogged filters restrict airflow and overwork the system.

Before summer:

  • Replace all filters
  • Verify correct filter sizing
  • Check return air paths

Poor airflow causes frozen coils, overheating, and shutdowns.

Check Electrical Components

Electrical failures spike during summer.

Critical inspections include:

  • Capacitors
  • Contactors
  • Wiring connections
  • Control boards

Catching weak components early prevents mid-season outages.

Verify Refrigerant Levels

Low refrigerant reduces cooling and increases system strain.

Pre-summer checks:

  • Confirm proper charge
  • Inspect for leaks
  • Verify pressure readings

Low refrigerant often shows up as “it can’t keep up” on hot days.

Test Thermostats and Controls

Controls drive performance.

Make sure:

  • Thermostats are calibrated
  • Scheduling matches occupancy
  • Zones respond correctly
  • Setpoints make sense for summer load

Bad control logic wastes energy and stresses equipment.

Evaluate System Age and Performance

Summer exposes weak systems fast.

If your system:

  • Struggled last summer
  • Is over 15 years old
  • Has a history of emergency calls

Now is the time to plan—not wait.

Why Pre-Summer Prep Matters More in Memphis

Memphis heat doesn’t forgive delays.

Once summer hits:

  • Emergency labor costs rise
  • Equipment availability tightens
  • Downtime risks increase
  • Decisions get rushed

Preparation protects comfort, budgets, and operations.
