Room Air Conditioner Repair in Houston
We repair LG window, portable and through-the-wall air conditioners that plug in. Ducted or mini-split systems need a licensed HVAC contractor. Weak cooling, leaks and noise are our usual calls.

Common room air conditioner problems we fix
In the order we see them across Houston homes.
Runs but blows air that is not cold
Condensate dripping into the room
Ice forming on the front coil
Loud rattle, buzzing or fan scrape
Remote or app control not responding
Trips the breaker or will not start
Room air conditioners from LG include window, portable and through-the-wall units, many with inverter compressors and ThinQ app control. They are self-contained, which means the cooling system, fan, controls and drain sit in one box.
Houston puts these units through long, humid seasons. Filters and coils clog with dust, condensate lines gum up, and a unit that runs day and night wears fan motors. Storm outages and voltage swings can also upset the control board of an inverter model.
We check the filter and coil, the fans, the drain path, the sensors and the electrical supply, then the sealed system only if the signs point there. We tell you plainly when a unit is not worth repairing. Ducted systems and mini-splits are outside what we service.

My room air conditioner runs but does not cool. What should I check?
Clean the filter, make sure the vents are clear and the room is closed. A dirty filter or a blocked coil cuts cooling sharply. If it still blows warm air or ice forms, the cause may be low refrigerant or a failed part, which we test.
Why is water dripping inside the room?
Most units drain condensate toward the outside, so the unit usually needs a slight tilt toward the back. A blocked drain, a clogged filter or a heavy ice buildup can send water inside. Check the tilt and the filter, then book a visit if it continues.
Do you repair ducted or mini-split systems?
No. Those need a licensed HVAC contractor. We repair the plug-in kind: window, portable and through-the-wall units. If you are not sure which you have, describe where it sits and how it is powered.
