Introduction to Air Conditioner Issues

Air conditioner problems can arise from various factors, including maintenance, installation, and usage. In this article, we’ll explore the common causes of an air conditioner not cooling and provide a practical checklist for homeowners to diagnose the issue.

A clogged air filter can restrict airflow, causing your air conditioner to work harder and reducing its cooling efficiency. Check your air filter and replace it if necessary.

Inspecting the Condenser Coils

Dirty condenser coils can also reduce your air conditioner’s cooling performance. Inspect the coils and clean them if necessary.

Before calling an HVAC technician, perform the following checks:
