AC running but not cooling? Know your next step.

Describe the symptoms. Let the professional assess the system.

If the system is running but not providing the cooling you expect, a useful first conversation starts with observations: when the problem began, whether it affects the whole home, and anything that changed recently. Those details help frame the discussion; they are not a diagnosis.

Ask what a service visit includes and whether there is a diagnostic or visit fee. Confirm how you will hear the findings and approve any proposed work. Do not assume a phone conversation books a visit or commits you to a repair.

This guide focuses on an AC that runs but does not cool as expected. A unit that will not start, a heating problem or a commercial system may require a different service conversation. For immediate danger, use appropriate emergency assistance rather than relying on this site to assess the situation.

Your AC conversation checklist.

Keep these points nearby when speaking with a service business. You do not have to enter them on this website.

• Describe what is happening in plain language and when you first noticed it.
• Explain whether the cooling problem affects one room or the whole home.
• Say when you need assistance; ask what scheduling options the business can actually offer.
• Ask who will assess the system, what the visit includes, and what fees may apply.
• Ask how findings and a written estimate will be shared before work is approved.
• Mention any warranty or recent service paperwork you already have, if relevant.

A useful conversation should leave you clearer about the next step, not pressured to approve work you do not understand. Keep a copy of the estimate and any terms you agree to.

If repair or replacement comes up, ask why.

Ask the professional to explain the diagnosis and the alternatives. What would the recommended repair address? What is included in a replacement proposal? Are there relevant warranty terms, exclusions or further checks? You can ask for clarification before choosing.

Compare the proposed scope, not just the headline price. A written estimate helps you see which tasks, equipment and terms are included. Our guide to reading a home-service quote explains the questions worth asking.
