After inspecting thousands of properties across the Denver Metro, I can tell you that HVAC deficiencies remain one of the most frequent and easily preventable issues that show up on inspection reports, particularly as summer ramps up.

For seasoned agents like you, this isn’t news, but it’s a solid reminder that a little proactive HVAC attention can prevent unnecessary friction during contract and inspection phases. Whether your client is listing or getting ready to buy, encouraging a proper clean and service can help preserve value, prevent credits, and ease buyer concerns before they snowball.

What Does an AC Clean & Service Actually Include?

Most licensed HVAC techs will complete the following:

  • Clean the condenser coils – Dust and debris buildup can reduce system efficiency by up to 30%.
  • Test refrigerant levels – Identifies low charge or leaks that often lead to poor cooling performance or compressor strain.
  • Inspect electrical and motor components – Worn-out parts and loose connections are often behind mid-summer breakdowns.
  • Flush and clear the condensate drain – A clogged line can cause ceiling leaks, water damage, and microbial growth—especially in homes with attic air handlers.
  • Calibrate the thermostat and verify proper cycling – Prevents rapid cycling and confirms accurate temperature control.
  • Replace or assess filters – Improves airflow, air quality, and system longevity.

Think of it as the HVAC equivalent of a 60,000-mile service – not exciting, but it keeps deals (and systems) running smoothly.
