Air Conditioner Repair Requests
Requests cover window, portable and through-the-wall room air conditioners that blow warm air, won’t start, drip water or run noisily. Central HVAC is not included.
Room air conditioners pack a compressor, fans and coils into one compact box, so dirty filters, blocked airflow and drainage issues show up quickly. People often ask for help when a window or portable unit blows lukewarm air, cycles off, drips into the room or starts rattling. Central air and ducted systems fall outside these requests.
Describe the type of unit and its symptoms in your request. We share it with independent local repair professionals, who may contact you, inspect the unit and quote their own price before any repair you agree to.
Signs Your Air Conditioner May Need a Professional
- Air feels barely cool or airflow is weak
- The unit won’t power on or keeps shutting off
- Water dripping indoors instead of outside
- Rattling, buzzing or squealing sounds
Common Air Conditioner Problems
Blowing warm or weak air
This is often caused by a clogged filter, dirty coils or a fan motor that has slowed down. A technician may also look at the thermostat sensor, the capacitor that helps start the compressor and whether refrigerant is low because of a leak.
Unit won’t turn on
A unit with no power may have a tripped breaker, a plug with a built-in safety device that needs resetting, a damaged cord or a failed control board. Some units also stop running when an internal overload protector senses overheating.
Water leaking inside
Indoor drips can be caused by a window unit tilted the wrong way, a clogged drain channel or a frozen evaporator coil thawing out. Portable units may leak when the internal water tank is full or the drain hose is disconnected.
Noisy operation
Rattling frequently comes from loose mounting, panels or debris inside the housing. Buzzing can point to an electrical part such as a capacitor or relay, while squealing may indicate worn fan motor bearings.
Safe Things to Check First
- Remove and clean the washable filter, or replace a disposable one
- Check the plug for a reset button and confirm the outlet works
- Move curtains, blinds or furniture away from the front grille
- Empty the water tank on a portable unit if it has one
Safety: Unplug the unit before cleaning the filter, and don’t open the cabinet. Room air conditioners contain refrigerant, which under EPA rules may only be handled by technicians holding EPA Section 608 certification.
What to Include in Your Request
- Brand, model and serial number, often found on a sticker on the side of the cabinet or behind the front grille
- Whether it is a window, portable or through-the-wall unit
- Any error code or blinking light on the control panel
- How long the unit runs before the problem appears
Air Conditioner Repair FAQs
Does this cover central air conditioning?
No. Requests here are for window, portable and through-the-wall room air conditioners. Central air systems, heat pumps and ductwork usually call for an HVAC contractor, so consider contacting one directly for those systems.
Is it worth repairing a window air conditioner?
It depends on the unit’s size, age and which part has failed. Smaller units may cost less to replace than to fix, while larger or through-the-wall models are often worth a diagnosis. Ask the repair professional for a quote to compare.
Why does my air conditioner freeze up?
Ice on the coils is often caused by restricted airflow from a dirty filter or coil, or by running the unit when it is cool outside. Low refrigerant can also be a factor. Turn the unit off and let it thaw before describing the issue in a request.
