Air conditioners are designed to bring cool comfort to your home. So if it starts blowing warm air into your space, you better believe there’s a problem.
But what might cause an air conditioner to start blowing out lukewarm air?
Here are some of the most common reasons:
- Airflow blockages can cause problems with temperature exchange and thus prevent your AC from providing cool air.
- A damaged compressor may become inefficient at pumping essential refrigerant throughout the unit, reducing its ability to replace warm ambient air.
- Over time, refrigerant lines can become damaged, causing a leak and reducing cooling performance.
- Improper thermostat settings can make your air conditioner blow warmer air than you prefer
- An old, worn air conditioner may slowly surrender, revealing its age with poor ability to produce cool air.
Air conditioners don’t produce cold air. Instead, the system removes warm air from your home fairly simply. This makes it relatively easy to find the culprit if and when your air conditioner starts blowing out warm air.
Reasons Why Your AC Is Blowing Warm Air
1. Airflow Blockage
Your air conditioner cools your space by way of a substance called refrigerant. This chemical changes from a gas to a liquid state and vice versa as the compressor pumps it throughout the air conditioning unit.
Refrigerant absorbs heat from your space and releases it outside through these changes.
But refrigerant doesn’t just magically magnetize heat. So your air conditioner needs to uptake your ambient air, blow it over the refrigerant in the coils, and then the temperature exchange happens.
Any airflow obstruction can prevent this exchange from happening. For example, a dirty filter or dirt-encased evaporator coils could reduce the amount of warm air blown over the coils, thus blocking the process.
As a result, your air conditioner might start to blow out warm air. This comes as the result of a poor temperature exchange.
The best way to solve the problem would be to clean the filters and remove other blockages obstructing airflow.
2. Damaged Compressor
You can think of the compressor as the heart of your air conditioner. This powerful internal mechanism pumps refrigerant throughout the system for efficient cooling performance.
When the compressor is damaged, refrigerant flow through the system may become significantly impaired.
When there isn’t any or enough refrigerant flowing through the air conditioner, collected heat has nowhere to go.
So instead of being absorbed by the refrigerant and carried outside, the heat remains in the air conditioner and is blown back into your home.
A damaged compressor may be repaired, but a replacement may be the only solution in certain situations.
Make sure to call your HVAC specialist to find out what they recommend.
3. Refrigerant Leak
The constant movement of refrigerant through your air conditioning system may cause damage to the ducts that carry the substance.
Over time, cracks and breaks can develop in the refrigerant lines, causing the chemical to leak. This reduces the air conditioner’s efficiency and impairs its ability to absorb heat and replace it with cool air.
Regarding a refrigerant leak, the only solution would be to call an HVAC specialist.
This substance can be particularly dangerous. Do not attempt to repair a refrigerant line or replenish refrigerant levels if you don’t have experience handling the substance.
4. Wrong Thermostat Settings
Sometimes, the warm air blowing out of your air conditioner is just an oversight.
Air conditioners these days can let you set your temperature relatively warm, and this might seem like a problem unless you double-check the thermostat.
Other models even have a heating function. Enabled by a ‘sun’ labeled button on the control panel or remote control, the heating function makes your space warm during the winter.
An accidental push of the heating button can cause warm air to fill your home when you don’t need it.
Take a moment to double-check your settings. Set the right thermostat to keep your space cool and comfortable.
5. End of Lifespan
Your air conditioner has a lifespan that most manufacturers set at about 10 years. After this period, your unit becomes more prone to damage, malfunction, and errors.
Of course, you shouldn’t jump to conclusions if your air conditioner is blowing warm air. But if none of the previous explanations can fix your AC, you might have to consider its lifespan.
Unit damage can accumulate over time, especially if you don’t have it serviced routinely. As time wears on, these damages become more pronounced until your unit reaches its breaking point.
While an HVAC specialist can perform repairs, the service cost may come to par with a brand-new unit.
It’s not normal for an air conditioner to start blowing warm air. So as soon as the malfunction shows, you find the root cause to solve the problem before it worsens.
Be ready for the worst, though. If your unit is old and worn, warm air might indicate it’s time to buy a replacement.
Frequently Asked Questions
Is It Normal for an Air Conditioner To Blow Warm Air When It Starts?
Yes, it’s normal for an air conditioner to blow hot air first. Because the system has just started, it won’t be able to provide a cool breeze immediately after being turned on.
So you should expect a gentle warmth to blow out of the vents when you switch on the power. The warm air should be momentary, however.
If it persists and doesn’t cool, you have a problem.
Why Is My AC Not As Cold as It Used To Be?
If the air coming out of your AC isn’t necessarily warm but isn’t as cold as it usually is, you might be looking at the same issues.
Any problems that reduce the cooling efficiency of your air conditioner can be traced back to the reasons listed above.
Call a professional to check your air conditioner if you notice it isn’t performing as well as it used to.
Vifaa vya kuyeyusha hewa vimetengenezwa ili kuleta starehe nzuri nyumbani mwako. Kwa hiyo ikiwa huanza kuvuta hewa ya joto ndani ya nafasi yako, ni bora uamini kwamba kuna tatizo. Lakini ni nini kinachoweza kusababisha kifaa cha kusafisha hewa kuanza kutoa hewa yenye joto la chini? Hapa ni baadhi ya sababu za kawaida: - Vizuizi vya mtiririko wa hewa vinaweza kusababisha matatizo na kubadilishana joto na hivyo kuzuia AC yako kutoka kutoa hewa baridi. - compressor kuharibiwa inaweza kuwa inefficient katika pumping muhimu refrigerant katika kitengo, kupunguza uwezo wake wa kuchukua nafasi ya hewa ya joto mazingira. - Baada ya muda, mistari ya baridi inaweza kuharibiwa, kusababisha uvujaji na kupunguza utendaji wa baridi. Mipangilio isiyofaa ya thermostat inaweza kufanya kiyoyozi chako kipe hewa ya joto kuliko unavyopenda - Kiyoyozi cha zamani, kilichovunjika kinaweza kujisalimisha polepole, ikionyesha umri wake na uwezo mbaya wa kutengeneza hewa baridi. Vifaa vya kuyeyusha hewa havitokezi hewa baridi. Badala yake, mfumo huo huondoa hewa ya joto kutoka nyumbani mwako kwa urahisi. Hii inafanya iwe rahisi kupata mtendaji ikiwa na wakati kiyoyozi chako kinaanza kupumua hewa ya joto. Sababu za Kiyoyozi chako Kutoa Hewa ya Joto Kuzuia Mtiririko wa Hewa: Kifaa chako cha kuyeyusha hewa hufanya chumba chako kiwe baridi kwa kutumia kitu kinachoitwa kichocheo. Kemikali hii hubadilika kutoka hali ya gesi hadi hali ya kioevu na kinyume chake wakati compressor inapopomba katika kitengo cha hali ya hewa. Refrigerant huchukua joto kutoka kwa nafasi yako na kuitoa nje kupitia mabadiliko haya. Lakini kioevu haichukui joto kwa njia ya kichawi tu. Kwa hiyo, hali ya hewa ya hewa inapaswa kuchukua hewa ya mazingira, kuifurika juu ya kioevu katika coils, na kisha kubadilishana joto hutokea. Kizuizi chochote cha mtiririko wa hewa chaweza kuzuia kubadilishana huko kutokea. Kwa mfano, kichujio cha uchafu au coils evaporator kuzungukwa uchafu inaweza kupunguza kiasi cha hewa ya joto blown juu ya coils, hivyo kuzuia mchakato. Kwa sababu hiyo, huenda kiyoyozi chako kikaanza kutoa hewa yenye joto. Hilo hutokea kwa sababu ya kubadilishana joto vibaya. Njia bora ya kutatua tatizo hilo ingekuwa kusafisha vichungi na kuondoa vizuizi vingine vinavyozuia mtiririko wa hewa. 2. Uwezekano wa kupata Compressor ya hewa ya kawaida ni sehemu ya moyo wa mfumo wa hewa wa hali ya juu. Utaratibu huu wa ndani wenye nguvu hupomba kioevu katika mfumo wote kwa utendaji mzuri wa baridi. Wakati compressor ni kuharibiwa, mtiririko wa baridi kupitia mfumo inaweza kuwa kwa kiasi kikubwa kudhoofika. Wakati hakuna au kutosha refrigerant mtiririko kupitia kiyoyozi, joto zilizokusanywa hana mahali pa kwenda. Badala ya kuingizwa na baridi na kusafirishwa nje, joto linabaki ndani ya kiyoyozi na kurudishwa nyumbani. Kompresor iliyoharibiwa yaweza kurekebishwa, lakini kubadilishwa kwaweza kuwa suluhisho pekee katika hali fulani. Jitahidi kuwasiliana na mtaalamu wako wa HVAC na uone ni nini kinachohitajika. 3. Uwe na mtazamo wa kweli Kuvuja kwa Refrigerant: Mzunguko wa mara kwa mara wa Refrigerant kupitia mfumo wako wa hali ya hewa unaweza kusababisha uharibifu wa mifereji ambayo hubeba dutu. Baada ya muda, kunaweza kuwa na nyufa na kuvunjika katika mistari ya kioevu, na hivyo kemikali hiyo ivute. Hii hupunguza ufanisi wa kiyoyozi na kudhoofisha uwezo wake wa kunyonya joto na kubadilisha kwa hewa baridi. Kwa sababu ya kuvuja kwa friji, suluhisho pekee ni kumwita mtaalamu wa HVAC. Dutu hiyo yaweza kuwa hatari hasa. Usijaribu kurekebisha mstari wa baridi au kujaza viwango vya baridi ikiwa hauna uzoefu wa kushughulikia dutu hiyo. 4. Uwe na uhakika Wakati mwingine, hewa ya joto inayovuma kutoka kwa kiyoyozi chako ni uangalifu tu. Kwa sababu ya hali ya hewa ya kawaida, unaweza kuweka joto la joto kwa muda mrefu, na hii inaweza kuonekana kama tatizo isipokuwa kama wewe mara mbili kuangalia thermostat. Mifano mingine hata ina kazi ya kupasha joto. Kuwezeshwa na "juu" alama kifungo juu ya jopo kudhibiti au kudhibiti mbali, kazi ya joto hufanya nafasi yako joto wakati wa majira ya baridi. Kushinikiza kwa bahati mbaya kitufe cha joto kunaweza kusababisha hewa ya joto kujaza nyumba yako wakati huna haja yake. Chukua muda kuchunguza upya mipangilio yako. Weka thermostat sahihi ili kuweka nafasi yako baridi na starehe. 5. Uwe na mtazamo mzuri. Kwa mfano, kifaa chako cha hali ya hewa kina maisha ambayo wazalishaji wengi huweka kuwa miaka kumi. Baada ya kipindi hiki, kitengo chako kinakuwa na uwezekano mkubwa wa kuharibiwa, kutofanya kazi vizuri, na makosa. Bila shaka, hupaswi kukata kauli haraka-haraka ikiwa kiyoyozi chako kinatoa hewa yenye joto. Ikiwa hakuna moja ya maelezo ya awali ambayo yanaweza kurekebisha AC yako, unaweza kuwa na kuzingatia maisha yake. Uharibifu wa kitengo unaweza kukusanywa kwa muda, hasa kama huna huduma ya kawaida. Kadiri wakati unavyopita, uharibifu huo unakuwa mkubwa zaidi hadi kitengo chako kifikie kiwango cha kuvunjika. Wakati HVAC mtaalamu anaweza kufanya matengenezo, gharama ya huduma inaweza kuja sawa na kitengo kipya kabisa. Si jambo la kawaida kwa kifaa cha kuyeyusha hewa kuanza kuvuta hewa ya joto. Mara tu tatizo linapoonekana, utapata chanzo cha tatizo hilo kabla hali haijabadilika. Hata hivyo, uwe tayari kwa jambo baya zaidi. Kama kitengo yako ni ya zamani na kuvaa, hewa ya joto inaweza kuonyesha ni wakati wa kununua mbadala. Maswali yanayoulizwa Mara nyingi Je, ni jambo la kawaida kwa kiyoyozi kutoa hewa ya joto kinapoanza kufanya kazi? Ndiyo, ni kawaida kwa kiyoyozi kuvuta hewa moto kwanza. Kwa sababu mfumo umeanza tu, haitaweza kutoa upepo baridi mara moja baada ya kuzungushwa. Kwa hiyo unapaswa kutarajia joto la upole kuvuma nje ya mashimo ya hewa unapowasha umeme. Hata hivyo, hewa yenye joto inapaswa kuwa ya muda mfupi. Ikiwa inabaki na haipumzikii, una tatizo. Kwa Nini Kiyoyozi Changu Hakikuwa Baridi Kama Ilivyokuwa? Kama hewa inayotoka AC yako si lazima joto lakini si baridi kama ni kawaida, unaweza kuwa kuangalia masuala sawa. Matatizo yoyote ambayo hupunguza ufanisi wa baridi ya kiyoyozi yako yanaweza kufuatiliwa nyuma ya sababu zilizoorodheshwa hapo juu. Piga simu mtaalamu kuchunguza kiyoyozi yako kama unaona si kufanya kama vile ilivyokuwa.
