Whenever your air conditioner needs to be repaired, and sometimes after it has been repaired and switched on, it may take some time before your home temperature returns to normal. It can affect how quickly an AC system cools down the house getting repaired.
Time required to get the temperature set
Length of Downtime
The period your AC was out of order significantly determines how long it takes to cool your house after repairs.
A few critical timeframes:
- Less than 12 hours downtime: If your AC was only off for less than half a day, it should cool back to the right temperature within 30 minutes to an hour of the repairs being done.
- 12 to 24 hours downtime: If the AC was off for 12-24 hours when you switch on the AC after repair, it might take probably one to three hours to come into the set temperatures.
- Over 24 hours downtime: The colder the temperature, the longer it takes for the AC system to kick back in and cool the home. If it was broken for over a day it could take 3 or more hours for your home to cool or heat up depending on what type of AC you have once you switch it back on after the repairs.
AC System Capacity
The size of air conditioning not only determines the ability to cool your house and the rate at which it will do this. An appropriately sized unit for your square footage should be able to cool a house far faster than a smaller one.
Properly sized unit: If proper sizing of the AC had been done, it ought to cool the home within a reasonable time, other than if it took more than a day off.
Oversized unit: A larger unit will cool the house slower than a unit designed to match the home’s square footage. Instead, it just turns on and off more often rather than staying on long enough to remove humidity and stabilize temperature.
Undersized unit: A system that is too small for the house will never be able to cope during scorching weather. After moving between the rooms for repairs, it can take hours to gradually cool the house down but the desired temperature may be hard to achieve. Such a point indicates that there is a problem with capacity.

Weather and Humidity
The prevailing outdoor temperatures and relative humidity after the repairs on your central AC also dictates how long it takes to condition specific rooms indoors.
Extreme Heat
If the outdoor ambient temperature is 95°F + when you switch on your air conditioning system after repairing it, take long before you feel an excellent air circulation than if the outdoor air was just 80°F. The warmer it is outside; it takes a longer time for the cool air to carry out a winning battle against that heat wave which has just invaded the house. Humidity also affects relaxed down process as the air with high humidity takes more time to cool down than the air with less moisture content.
Milder Temperatures
As outside conditions are more excellent in the seventies or eighties, or less humid when you switch on your AC again, you will get a chill in half an hour to an hour. There is nothing as comfortable as having mild weather since an AC system’s work is significantly eased.
How to Cool Faster After Home Repairs
To help your AC system cool your home more quickly after repairs, follow these tips:
- Close all windows and doors
- Keep all vents fully open
- The easiest way to cool down your home is to switch off the appliances that produce heat.
- Avoid using oven or stove
- Tidy up the room and draw all the blinds curtains closed
Following the above steps and because the duration of AC downtime was relatively short your home should cool back down in one to three hours after repairs even during a hot weather. However, if it takes much longer than that, give the AC repair company a call back as your system may be sized wrong or there could be another problem. But then again if you live in a relative moderate climate, you should start noting the difference immediately you restore use of your AC.
Conclusion
The time it will take an AC system to cool down a house depending on the time it took to make the repairs depends on; the duration the AC system was off; the capacity of the AC system and the prevailing weather conditions outside. At substantially high temperatures and a pause of 24 hours and more, it takes three hours or more to sense a difference in temperature. In essence, if the downtime had been less than 12 hours, and weather is moderate, the cooled air probably can start circulating through your home an hour after you flipped the switch on your repaired AC unit back. Some actions to help your AC cool faster include; turning off other appliances that could create heat, closing windows and adjusting the thermostat to a lower temperature after fixing the equipment.
