Sizing before anything gets bought
We measure the window opening or the wall sleeve and the room it has to cool, so the unit fits the hole and the load.
We supply the unit and install it
Tell us the room and we source a unit that fits, then put it in. Install is priced by scope and quoted on the call.
Or we install the one you bought
Already have a unit in the box? We mount it, seal the gaps, and set the tilt so condensate drains outside.
Straight repair-versus-replace math
The trade rule is 50%: if a fix costs more than half of replacing the thing, replace it. On window units it usually does.
Old unit removal, ask when you call
Buildings have their own rules about bulky items, so ask and we'll sort out where the old one goes before the visit.

Do you repair window air conditioners?
No. Not the window boxes, and not the through-the-wall sleeve units or PTACs either. We replace them, and the reason is money rather than squeamishness. The compressor in one of these is a small hermetic rotary that can’t be rebuilt, only swapped whole. Reaching it means recovering the refrigerant, cutting the sealed system open, brazing, pulling a vacuum, and recharging. That is hours of skilled work on a machine you can buy new for a few hundred dollars.
The math, side by side
HomeAdvisor puts a 2026 window AC repair at $229 on average, with a normal range of $105 to $359. Individual parts sit lower, of course: a capacitor is $10 to $60, a fan motor $100 to $300, a control board $50 to $250, a coil $100 to $200, and a professional refrigerant recharge $100 to $250. Add the labor to reach any of them.
Now the other column. A 5,000 BTU unit runs $170 to $249 today. Six thousand BTU sits between $249 and $399, and Consumer Reports’ 2026 top pick for a 150 to 250 sq ft room, the LG LW6023IVSM, is $399. Eight thousand BTU runs $265 to $449.
The trade has a rule for exactly this decision, the 50% rule: once a repair costs more than half of replacing the equipment, replace it. A $229 average repair against a $199 unit isn’t a close call.
Consumer Reports is blunt about the specific complaint that brings most people to this page. When a window unit blows warm air, the likely cause is the compressor or the refrigerant level, and the unit should be replaced if it’s out of warranty.
There’s a slower reason too. R-410A is being phased down in favor of A2L refrigerants like R-32 and R-454B, so paying to open up an older sealed system makes a little less sense every year. We’re EPA Section 608 Universal certified, which is what the law requires to touch refrigerant at all, and that certification is exactly why we can tell you what the job involves instead of guessing at it.
What we do instead
Two ways, your pick. You buy the unit and we install it, or we source the right one and install it. Either way the measuring comes first: the window opening or the wall sleeve, plus the room it has to cool. A 5,000 BTU box is built for a small bedroom, and asking it to cool a large living room means it runs all afternoon and never catches up. Going too big backfires differently. An oversized unit short-cycles, so the room ends up cool and clammy instead of cool and dry.
Installation is priced by scope, so we quote it on the call once we know what’s going in and what it’s going into. If the old unit has to disappear, ask about that when you call, because buildings differ on bulky-item rules and it’s better sorted before the visit than during it.
Try these first, they’re free
Pull the filter, wash it, let it dry, put it back. Clear the drain path and the weep hole at the back so water runs outside instead of down your wall. Rinse the condenser fins on the outdoor half, since a felt of dust there quietly costs you capacity. Check the outlet, the breaker, and the reset button on the power cord. Any of those four can bring the cooling back, and none of them are worth paying anyone for.
The AC work we do handle
Plenty of air conditioning is still our job. AC tune-ups on central systems, mini-split service on ductless equipment, and thermostat installation when the control is the actual problem. The full list lives on our HVAC services page. Roughly 70% of our jobs run the same day.

Common symptoms and what they mean
-
It runs but the air comes out warm
Likely causes and our verdict:
- Compressor or refrigerant level, per Consumer Reports
- The sealed system has to be recovered, cut open, brazed, vacuumed and recharged to reach either one
- A window compressor is a small hermetic rotary: it can't be rebuilt, only swapped whole
- Verdict: replace the unit. Consumer Reports says the same once it's out of warranty.
-
Airflow is weak and the room won't cool down
Likely causes and our verdict:
- Clogged filter, which is the first thing to check
- Condenser fins packed with dust on the outdoor side
- Furniture or a curtain blocking the return
- Verdict: free fix. Wash the filter, rinse the fins, clear the front.
-
Water dripping into the room
Likely causes and our verdict:
- Blocked drain path or weep hole at the back of the pan
- The chassis sits dead level instead of tilting slightly toward the outside
- A frozen coil thawing all at once
- Verdict: usually free to clear yourself. A cracked pan means replacement.
-
Nothing happens when you turn it on
Likely causes and our verdict:
- The reset button on the plug has tripped (most cords carry a GFCI head)
- Breaker tripped, or the outlet itself is dead
- The unit's internal overload has cut out on a hot day
- Verdict: free to check. Dead unit on a live outlet means replacement.
-
Ice building on the coils
Likely causes and our verdict:
- Restricted airflow from a dirty filter starves the coil
- Low refrigerant charge, which on a sealed box means a leak
- The unit is running in weather colder than it was built for
- Verdict: clean it and let it thaw. If the ice comes back, replace the unit.
-
Grinding, rattling, or a burnt smell
Likely causes and our verdict:
- Loose mounting brackets in the window frame rattle under vibration
- Fan motor bearings gone dry
- Scorched wiring or a failing compressor draws hard enough to trip the breaker
- Verdict: unplug it now. A burnt smell or a tripping breaker is a stop sign, and this is replacement territory.
Frequently asked questions
Do you repair window air conditioners?
No. Not window units, and not the through-the-wall sleeve type or PTACs either. A window unit's compressor is a small sealed rotary that can't be rebuilt, only swapped whole, and reaching it means recovering the charge, cutting the sealed system open, brazing, pulling a vacuum, and recharging. That is hours of skilled work on a machine that sells new for a few hundred dollars. So we replace these units instead, and we'll tell you that on the phone rather than after a service call.
What does a new window AC cost in 2026?
Street prices right now: 5,000 BTU runs $170 to $249 (the Midea MAW05M1BWT at $170, the GE AWCS05BWA at $179, the Frigidaire FFRA051WAE at $199). 6,000 BTU runs $249 to $399, and the LG LW6023IVSM at $399 is Consumer Reports' 2026 top pick for a 150 to 250 sq ft room. 8,000 BTU runs $265 to $449, from the BLACK+DECKER BD08WT6 up to the Windmill. Installation is priced by scope and quoted on the call.
Can you install a unit I already bought?
Yes, that's one of the two ways we do this. You buy the unit wherever you like, we mount it, seal the gaps around the chassis, and set the tilt so condensate runs outside instead of down your wall. The other way is that we source the unit for you and install it. Same job either way, and the choice is yours. Call (213) 205-2055 with the room size and the window measurements.
What about an AC built into the wall?
Same answer, we don't repair those. Through-the-wall and PTAC units sit in a metal sleeve, and the sleeve usually stays put while the chassis is what gets swapped. That makes the opening the deciding factor, so we measure the sleeve before anyone buys anything. Wall units cost more to replace than window units, which is exactly why the measuring matters.
What should I check myself before calling?
Four things, none of which cost a dollar. Pull the filter, wash it, dry it, put it back. Clear the drain path and the weep hole so water goes outside. Rinse the condenser fins on the outdoor side, since a coat of dust kills capacity. Check the outlet, the breaker, and the reset button on the plug. If cooling comes back after any of that, you don't need us at all.
Do you fix any air conditioning at all?
Yes, quite a lot of it. Central AC tune-ups, mini-split and ductless service, and thermostat installation are all ours, and they're the pages linked from this one. Window and through-wall boxes are the one category we replace rather than repair. Appliance repair is the main business alongside that, from refrigerators to laundry. Call (213) 205-2055 and tell us what you have.
