Why is my AC running but not cooling the house?
Common causes include a dirty filter, a blocked outdoor unit, low refrigerant or a failing part. Check the filter and thermostat first. If air stays warm, a local provider can find the cause.
A warm house and a silent air conditioner can feel stressful, especially in an older home with past repairs and a few surprises behind the walls. You are not alone, and most cooling problems have a plain, fixable cause.

A warm house and a silent air conditioner can feel scary. Take a breath. Most cooling problems have a plain cause, and many can be fixed. Here is one clear step at a time, from the quickest checks to the moment you reach out for help.
If the breaker trips again, stop there. Repeated tripping points to an electrical fault that needs a professional.
Switch the system off at the thermostat and leave it off. Running it can turn a small repair into a big one.
Some situations are urgent. Think of a heat wave with a baby, an older relative, or someone with a health condition at home. Emergency AC repair is a fair thing to ask about in those cases. Many providers can respond quickly, though availability and hours vary. Request a callback to check provider availability in your area.
Small clues often show up before a full breakdown. Do any of these sound familiar?
One sign alone is worth a look. Two or three together mean it is time to book HVAC service.
Older houses are lovely, and they have quirks. Past owners may have added rooms, moved ducts or patched wiring. A provider has to work around all of that. Older homes, gentle care is a good rule to keep in mind.
In many Cape Cod style homes, the upstairs sits right under the roof and holds heat. Ducts may be narrow or squeezed into tight spaces. That can make cooling uneven even when the AC itself is healthy. A provider can tell you whether the unit or the duct layout is the real issue.
Full basements often hold the indoor unit. Damp air, old drain lines and rust can cause clogs and leaks. Stone and block walls make it harder to run new lines, so a repair may need extra planning. Thaw cycles and spring snowmelt can also shift the ground under an outdoor unit, leaving it tilted.
In a multi-family home, the electrical panel or cooling setup may be shared. Talk with your landlord or co-owners before work begins, so nobody is surprised.
If you have never had a repair visit, here is the usual flow.
Capacitors and contactors help the motors start. They wear out with age, so they are among the more common fixes.
Refrigerant is the fluid that carries heat out of your home. If the level is low, there is a leak somewhere. A solid repair finds and fixes the leak instead of only topping off the fluid.
A tired motor may hum, squeal or not spin at all. Some can be repaired, and some need replacing.
A clogged drain line causes water leaks. A dirty or iced-over coil blocks cooling. Both are common in older basements.
Plenty of repairs are worth doing. Replacement may be worth discussing if the unit is around 12 to 15 years old, needs a large part like a compressor, or breaks down summer after summer. Some providers suggest comparing options when a repair costs close to half the price of a new system. Ask for both numbers in writing, then take your time.
If your heating is aging too, you may find yourself searching furnace replacement near me. That is a separate question for a calmer day. Right now, focus on getting the cooling sorted. Choices about your whole heating and cooling setup can wait.
Ask before you agree. Here are good ones to keep handy:
After a snowy winter, ask a provider about a spring check-up. Change the filter every one to three months. Keep the outdoor unit level and clear of leaves and storm debris. Small habits like these help older systems last longer.
A provider checks the thermostat, electrical parts, airflow and refrigerant level to find the real reason cooling stopped.
You get the problem and price explained in plain words before work starts.
Providers can work around aging ducts, tight basements and past repairs without rushing.
If the unit is worn out, a provider can lay out both options so you can compare.
Prices change with the home, the part and the provider. These are typical U.S. ranges, not quotes. Older houses with tight spaces can cost more. Always ask for a written quote before you agree to any work.
| Repair item | Typical range | Notes |
|---|---|---|
| Diagnostic visit | $75 – $200 | Often applied toward the repair if you proceed |
| Capacitor or contactor | $120 – $450 | Common wear parts; quick fix on many visits |
| Condensate drain clearing | $75 – $250 | Helps stop leaks and water stains |
| Fan or blower motor | $400 – $1,100 | Depends on motor type and access |
| Refrigerant leak repair | $250 – $1,600 | Varies by leak location and refrigerant type |
| Compressor replacement | $1,200 – $3,000 | May lead to a repair-or-replace talk |
Look at the thermostat, breaker and filter, and clear the outdoor unit. Stop if you see sparks or smell burning.

Usually no. Grinding, squealing or banging can mean a part is failing. Switching the system off can prevent more damage. Then ask a provider to take a look.
Look at its age, how often it breaks and what the repair costs. If it is over 12 to 15 years old and needs a big part, ask a provider to compare options in writing.
