Summer HVAC Season: Why Vent and Coil Cleaning Belongs in Your Facility Plan

May 15, 2026 6 min read

When Atlanta hits 95° and your HVAC runs 24/7, dirty coils and vents become an energy bill and an air quality problem. Here's the cleaning protocol that protects both.

Every summer, Metro Atlanta facilities see their energy bills climb 20–30% — and most of that increase has nothing to do with the weather. It's dirty coils, clogged vents, and biofilm in drain pans forcing HVAC systems to work harder than they should.

The hidden cost of dirty HVAC components

  • A 1mm layer of dust on a cooling coil cuts efficiency by up to 21%
  • Clogged return vents force systems to run 15–30 minutes longer per cycle
  • Microbial growth in drain pans circulates allergens through every occupied space

What summer HVAC cleaning should include

  • Supply and return vent detail cleaning
  • Coil inspection and on-coil cleaning (where accessible)
  • Drain pan treatment and biocide application
  • Filter audit and replacement schedule documentation
  • High-dusting of all visible ductwork and registers

When to schedule

Late May through mid-June is ideal — before the worst heat hits and while energy rates are still pre-peak. Pair this with a spring deep clean and your facility runs cooler, cleaner, and cheaper through August.

We coordinate with your HVAC service provider so the work is sequenced correctly and nothing falls through the cracks.
