Getting your air conditioning system repaired brings a huge sense of relief, especially when you’re facing the intense heat and humidity of summer in Lithonia, GA. After scheduling AC repair and getting your unit back up and running, it’s natural to wonder how soon your home will feel comfortably cool again. While the repair fixes the underlying problem, cooling your entire house isn’t always instant. In fact, several important factors, like your home’s size, insulation quality, outdoor temperature, and even the age of your AC unit, all play a role in how quickly your living spaces return to the refreshing chill you’re craving. Many homeowners expect immediate results after AC repair services, but the real cooling timeline can vary widely. In this guide, you’ll learn what affects the cool-down process, how long you should expect it to take after repair, what you can do to help your home cool faster, and when it might be time to call experienced AC repair experts for a second look. Whether you’re living in Lithonia, Snellville, Tucker, or Conyers, understanding what happens after your air conditioner is fixed will help you enjoy faster comfort and better performance from your system.
How Long Should It Take to Cool My House?
In most cases, after a proper AC repair, your system should start blowing cool air within 15 to 30 minutes.
But for your entire home to feel comfortably cool? That could take 2 to 6 hours, depending on a few key things:
- How hot it was inside when the system was off
- The outside temperature (hello, Georgia heat!)
- How big your home is
- How efficient your AC system is
- The condition of your insulation and ductwork
If it’s been a few hours and your house still feels stuffy, that’s a sign it may not just be a cooling delay, your system might still need attention.
5 Real Reasons Your Home May Take Longer to Cool After AC Repair
1. Your AC System Might Be Undersized
Not all AC units are created equal — and not all are sized right for your home. A small system in a big house will struggle to cool efficiently, even if it’s just been repaired.
At CAL Heating & Cooling Solutions, our AC repair services always include a full system check to make sure your unit is right for your space. We don’t just patch it up, we help you plan for long-term comfort.
2. High Outdoor Temps in Lithonia Slow Things Down
We all know how brutal summers can be in Lithonia and nearby towns like Tucker or Lilburn. On days when it’s 90°F and up, your AC works overtime to remove heat from your home.
Even the best AC repair services can’t make Georgia summers disappear, but we can make sure your system is running as efficiently as possible to keep you cool.
3. Poor Insulation = Lost Cool Air
You could have the most powerful AC unit in town, but if your home has weak insulation, that cool air is escaping fast. Attics, walls, windows, if they’re not sealed properly, the air your AC is working so hard to create just drifts away.
Want to speed up the cooling process after a repair? Check your insulation. Our AC repair experts can point out where improvements will make the biggest difference.
4. Leaky Ductwork Slows Down Cooling
You’d be surprised how many homes we visit in Stone Mountain or Decatur, GA, with duct systems leaking air into attics or crawl spaces. If air can’t get to the rooms it’s supposed to cool, your house will take much longer to feel comfortable.
As part of our AC repair services, we inspect your ducts for leaks and recommend affordable fixes to help your system work smarter, not harder.
5. High Humidity Adds to the Struggle
AC systems don’t just cool your home, they also remove humidity. And here in Georgia, humidity is no joke. If your system isn’t removing moisture properly, your home will still feel warm and sticky even after repairs.
If this sounds familiar, our team can add solutions like whole-home dehumidifiers or upgrade your system for better moisture control. That’s why homeowners trust us as the best AC repair service in the area, we don’t just fix problems, we prevent them.
What Should Happen After AC Repair?
Here’s what to expect when your system is back up and running after a professional AC repair:
- Air blowing cool within 15–30 minutes
- A temperature drop of about 1–2°F per hour
- Even airflow across most rooms
- Quieter operation and reduced humidity
- No burning smells or strange noises
If that’s not what you’re seeing, it’s time to give your AC repair experts another call.

Frequently Asked Questions (FAQs)
How long should it take to cool my house after AC repair?
After a professional AC repair, cool air should start flowing from your vents within 15 to 30 minutes. However, depending on your home’s size, insulation, outdoor temperature, and system efficiency, it can take anywhere from 2 to 6 hours for your entire home to feel fully comfortable. If cooling takes longer than expected, it may be worth having AC repair experts inspect the system further.
Why is my house still warm after AC repair?
If your home is still warm hours after AC repair services, several factors could be at play. Poor insulation, duct leaks, high humidity, or an undersized AC unit could be preventing proper cooling. It’s also possible that additional issues were not fully addressed during the initial repair. In such cases, a follow-up inspection from the best AC repair services is recommended.
Can I speed up cooling after an AC repair?
Yes! After an AC repair, you can help your home cool faster by keeping doors and windows closed, using ceiling fans to circulate air, drawing blinds to block out sunlight, and avoiding activities that add extra heat indoors, like cooking or running dryers. These steps support the cooling process and reduce strain on your repaired system.
Is it normal for AC to take several hours to cool the house after repair?
Yes, it’s completely normal for your AC to take a few hours to cool your home after a repair, especially if the system had been off for a while and the home’s walls, floors, and furniture absorbed heat. In most cases, after a quality repair, you’ll feel noticeable improvements within the first few hours, but achieving full comfort may take longer, particularly on extremely hot days.
When should I call back the AC repair experts after service?
If you don’t feel cooler air within 30 minutes, if some rooms remain warm, if your system runs constantly without reaching the set temperature, or if you notice unusual smells or noises, it’s time to contact your AC repair experts again. They can re-evaluate your system to make sure the issue is fully resolved and your cooling is working as efficiently as it should.
