How To Unfreeze Window Ac Unit
If you see ice on either your indoor or outdoor unit, information technology's a clear sign that something's wrong with your Ac unit.
The worst office? If you go along running the AC, you risk damaging the compressor—a $1,495+ AC repair (more on that later).
That said, follow these steps to unfreeze your AC unit quickly:
- Plough the thermostat from COOL to OFF
- Plough the fan setting to ON
- Cheque your filter and supercede it if needed
- If the filter isn't dirty, call a professional before turning the AC dorsum on
Annotation:These instructions will but help your AC to unthaw just won't guarantee the prevention of further damage due to falling ice chunks, h2o on controls, h2o damage, etc.
In this article, we'll explicate the rationale behind each of the steps higher up. We'll besides provide tips that volition help you preclude expensive water harm, or worse—a busted AC unit of measurement.
Your AC is freezing up for a reason and but thawing out the unit of measurement won't prepare the root trouble. If you want to solve the trouble at the core, we can help. Just contact us for an air conditioning repair service.
Footstep 1: Turn the thermostat from Cool to OFF
Ice on the AC unit means the refrigerant, the liquid that cools your dwelling house'south air, is much colder than it should exist. And if that abnormally cold refrigerant is sent to the outdoor unit of measurement, it could kill your compressor. The compressor should simply ever receive refrigerant in the course of a superheated gas—NOT a cold liquid.
Hither'southward the bottom line: Turning the thermostat from COOL to OFF stops your Ac from continuously sending common cold refrigerant to your outside unit (where your compressor is located).
During good for you performance, your compressor should only e'er receive refrigerant in the form of superheated gas—Non a cold liquid.
Step 2: Plough the fan setting to ON
Turning the fan to ON forces your Ac'south indoor fan to blow warm air non-stop over your Ac'south frozen coils.This will assist the water ice thaw faster.
Tip: Don't turn your fan setting to AUTO. This setting but runs the blower motor during a cooling wheel—and remember, yous just turned the thermostat from COOLING to OFF so your Ac won't be going through any cooling cycles.
How long will information technology take for my Ac unit to thaw?
It tin can take anywhere fromi hour to over 24 hours to unfreeze your air conditioner. It all depends on the extent of the water ice buildup.
Every bit y'all're waiting for the unit to thaw, keep an middle out for:
- An overflowing bleed pan. If you can access your indoor AC unit of measurement, you may desire to put some towels on the floor surrounding the unit. This will help forestall h2o damage if the melting ice overflows the drain pan and leaks onto the floor.
- A clogged condensate bleed. As the water ice on your evaporator coil thaws, the water will drip into a condensate bleed pan so catamenia outside via a condensate bleed line (a white PVC piping). Sometimes, though, dirt picked upwardly along the way tin grade a clog in that drain line and cause water to backup and overflow.
3. Check your air filter and supercede it if needed
The most common culprit behind a frozen AC is a dirty/clogged air filter. So, bank check your air filter equally you lot wait for the unit to thaw out.
Pro tip: Check your filter as shortly as you turn the thermostat to OFF. The longer y'all wait, the more likely the water ice will cook onto your air filter and create a muddied puddle.
If your air filter looks similar to the filter beneath, change it out for a new filter immediately.
Even a thin layer of grit/clay on your air filter can cause major AC problems, so change it out even if the filter isn't quite as chock-full as the one above.
A dingy air filter "suffocates" your air conditioner. And when your air conditioner doesn't get plenty warm air flowing over your evaporator coil, the refrigerant within gets colder and colder. And retrieve,very cold refrigerant coils + moisture in the air = water ice.
I replaced my muddied filter, at present what?
If you but replaced a dirty filter, go on waiting until your Air conditioning has completely thawed out. In one case your Ac is unfrozen, plow the Air-conditioning back on and run the air normally butcontinue an middle on the unit for the next few days.
The dingy filter was most likely the problem but to ensure that at that place isn't some other bigger effect, watch for any water ice returning on the AC lines. If you notice whatsoever ice forming or observe other AC problems, telephone call a professional to inspect and diagnose your unit of measurement.
Step four: Don't accept a dirty filter? Phone call a professional person correct away
A muddied air filter isn't the only problem that can cause a frozen Ac—but it's the only trouble that you can solve on your own.
If yous checked your air filter and it's completely make clean, you have a more than serious Air conditioning problem, such as:
- A refrigerant leak
- Dirt on the evaporator ringlet
- A weak or bad blower motor
- Stuck or closed expansion valve
- Collapsed duct
- Any other number of AC problems
And don't ignore this problem. Otherwise, you'll go along dealing with a frozen Air-conditioning and eventuallyy'all'll stop up paying over $3,000 for a damaged compressor.
