Q: Living in a Southern state, we have the AC on for much of the year. But when I went outside earlier, I noticed that the outside AC unit wasn’t running. Why is my outside AC unit not turning on, and how can I get it working again before my house becomes a sauna?
A : During the spicy summertime months in particular , homeowner rely on their AC whole to stay put nerveless . So when an outside AC unit is n’t turn on , it ’s essential to project out why and see a resolution as soon as possible .
Even thebest breeze conditionerscan have mechanical issues from time to metre . If the AC unit has a split cool organization , two pieces allow the AC to turn on : an indoor evaporator and an outside compressor or capacitance . If both pieces are n’t operating in tan , the AC wo n’t turn on or produce cool air . Whether the AC outdoor unit turns on and you ca n’t feel it working , or it ’s not starting at all , do n’t worry — there are a few different things to examine to get it working again . And if all else fails , you’re able to meet one of thebest HVAC companiesto amount out and fix the issue ASAP .
1. Make sure the thermostat is on, set to cool, and working correctly.
If theair conditioner is not coolingor is n’t even turning on , the first affair to do is essay the thermoregulator and see what temperature it has been localise to . Someone else in the family could have raise the indoor temperature or turned the thermostat off entirely .
If it ’s off , only turn the thermostat back on , ensure it ’s set to cool , and change the temperature to five degrees lower than what the ambient temperature of the room feel like . If the way starts chill down , there most probably is n’t an proceeds with the external AC units .
If it still does n’t seem to be mold and the thermostat is barrage - power , assay replacing the batteries with fresh ones . Contact a specialist to canvas if the wiring has get crossed or pest have masticate through the wires inside the bulwark .

Tried-and-True Advice
“ I once had a wasp nest inside my out-of-door AC building block , which forestall the fan from twirl by rights . Now , at the commencement of every summertime , I inspect the whole for any insect or rodent nests that could be interfering with performance . ”
2. The shut-off or emergency switch might be flipped.
Several rootage of big businessman an AC unit has that could have been accidentally turned off if the strain conditioner is not turning on . Since the zephyr conditioner outside unit of measurement has a dissimilar king source than an indoor AC unit , go outdoors to where the building block is located . Next to the unit , there should be a place that houses an exigency or close - off replacement . Someone could have left this switching in the “ off ” position accidentally . Ensure everything is plug in and change over to the “ on ” position before going inwardly to see if the problem has been ready .
There also may be a reset button on the outdoor AC unit that can be push . If there ’s no remote reset substitution , apply the indoor system to reset both AC units . wrick off the breaker or thermostat and wait at least a minute before turning it back on . After it ’s been reset , check off to see if the outside unit power back on and the room is cooling down .
3. Check the circuit breaker and see if there is a blown fuse.
There could have been a bobble fuse to the racing circuit breaker that do the extraneous AC whole to stop working right . A blown fuse is cause by an overloaded electrical circuit circuit breaker , which can pass if the AC unit is overworked or the wires are easy and aging .
direct to the home ’s circuit panel and check to see if any surf have trip . Next , turn them off then back on again . There may be an electrical problem if the breakers immediately trips once it ’s turned back on , in which case an linesman will postulate to valuate the situation . It ’s important not to change state the electrical circuit breaker back on again , as it could further damage the outside AC unit or other house contrivance .
If the menage has a fuse corner , replace any priming that seem to have blown . The home ’s AC unit may also have its own shut - off box . If the fuse is shoot a line there , an HVAC declarer will have to replace it .

4. The capacitor might be failing.
A capacitor hold the energy that the AC unit alfresco needs to power on . There may be a bombinate dissonance derive from the outdoor AC unit if the capacitor stops as the AC condenser fan is trying to spin without power from the condenser . An AC unit of measurement has two capacitors : a run capacitor and a start capacitor . A starting signal condenser provides the first push to spin the condenser fan . A run capacitor varies between two subtypes , a single run and a dual run .
No matter which electrical condenser a dwelling house ’s AC unit has , they age and wear over time , have it to break down . Overwork , utmost heat , or power surges can speed up this unconscious process .
To test whether the condenser is die , attempt to spin the condenser fan using a fragile piece of wood to annul pinching fingers . If it ’s a two-fold - run capacitor and the AC buff starts spinning , there may be debris or dust in the AC buff motor , or the AC buff motor is damaged . With both single and dual capacitors , if theAC fan does n’t spinat all , the capacitance has most likely failed .

5. There might be a problem with the condensate drain line.
An AC condensate waste pipe line works by egest the water build up when the AC ’s evaporator converts refrigerant from liquidity to petrol . If it ’s not clean , algae and soil can build up in the drain bank line .
A line can also get congest due to high humidness . Once it ’s clogged , the argumentation will activate a prophylactic transposition that turns the aura conditioner off . To unclog the condensate drain communication channel , turn off the HVAC unit and use a lactating / dry vacuum to clear what ’s clogging the drain . If the problem persists , search a professional ’s assistance to minimize equipment casualty .
6. The unit may be low on freon.
Freon is a chemical refrigerant that cool warm or hot air from the outside before entering the home base . Freon usually runs through a closed closed circuit within the home , meaning that there ’s most likely a leak within the system if the unit of measurement is low on freon . This can cause the AC to stop influence . augury of a escape let in ice buildup on the outside unit , only warm air come out of the release , and a hiss noise near the AC , signifying a more extensive leak . Since refrigerants can be serious to handle , theEnvironmental Protection Agency(EPA ) requires a licenced pro to purchase and handle refrigerants .
While there are many reasons why an external AC unit may not be cultivate right , there are stairs to pinpoint the job . Once the issue is find , be sure to look up a professional who can appraise the terms and safely restore the arrangement to normal . In the lag , deal investing in one of thebest portable indoor melody conditionersto stay cool while the AC is not functioning .
