Cooling
When the air conditioner stops cooling
A homeowner checklist for weak airflow, warm air, short cycling, water near the indoor unit, and complete loss of cooling.
Short answer
Check the thermostat setting, filter, accessible breaker, and whether the outdoor unit is running. Turn the system off if you smell burning, see sparking, or find water near electrical components.
Questions for a provider
- What failed and how was it tested?
- Is the quoted work a repair or a system replacement?
- Are refrigerant, electrical, drain, and airflow checks included?
- What parts and labor warranties apply?
Compare the written scope
Diagnosis, access, repair, and closeout are different decisions.
Diagnosis
Ask what test isolated the fault and what evidence supports the recommendation. A symptom alone does not identify every underlying cause.
Included work
Confirm labor, materials, model numbers, permits, access, disposal, cleanup, startup, and any walls, floors, landscaping, or finishes that another trade must restore.
Closeout
Request invoices, warranty terms, permit or inspection records when applicable, equipment settings, test results, and clear instructions for operation and maintenance.
Verify before hiring
Use the responsible public source.
