Ac not cooling?

Asked June 16, 2026 by a contractor in Other HVAC Types (Handyman Mod)

If your AC is not cooling, there are a few common reasons why this might be happening. First, check your air filter to see if it's dirty or clogged. A dirty filter can restrict airflow and make it harder for your AC to cool your home efficiently. Make sure to replace your filter regularly, about every 1-3 months, to keep your system running smoothly.

Another common issue could be a refrigerant leak. If your AC is low on refrigerant, it won't be able to cool your home properly. This is a job for a licensed HVAC professional as working with refrigerant can be dangerous. The cost of repairing a refrigerant leak can vary depending on the extent of the leak and the type of refrigerant used, but you can expect to pay anywhere from $150–$400 for this type of repair.

It's also possible that your AC unit may need cleaning or maintenance. Over time, dirt and debris can build up on your unit, affecting its performance. You can try cleaning the outside of your unit with a hose to remove any dirt or debris. If this doesn't solve the issue, it's best to contact a professional for a more thorough cleaning. Overall, if your AC is not cooling properly, the best course of action is to contact a licensed HVAC professional to diagnose and repair the issue. They can provide you with an accurate assessment of what's wrong and give you a quote for the necessary repairs. It's always a good idea to get a few quotes from local professionals to compare prices and services before making a decision.

    If your AC isn't cooling, you've already identified a couple of common issues. Checking and replacing the air filter is a great first step, as a dirty filter can significantly impact airflow and efficiency. Aim to replace it every 1-3 months, depending on usage.

    If the problem persists, a refrigerant leak is a likely culprit. This issue requires a licensed HVAC professional due to the potential hazards associated with refrigerants. Repairing a refrigerant leak typically costs between $150 and $400, depending on the severity of the leak and the type of refrigerant involved.

    Another possibility is that your AC unit needs maintenance or cleaning. While you can clean the exterior with a hose, a professional can provide a deeper clean and check for any other issues.

    To ensure you get the best service and pricing, I recommend getting 2-3 local quotes from licensed HVAC contractors through Handyman.com. This way, you can compare their assessments and costs before proceeding with repairs.
