Is your air conditioner giving you trouble during a Decatur, Indiana, heat wave? You’re definitely not the only one. When outdoor temperatures climb into the 90s, air conditioners are running almost nonstop, and extreme heat can expose worn parts, airflow problems, and other issues that weren’t obvious before.
In this blog, Doc Dancer Plumbing, Heating, A/C & Generators shares the biggest AC problems during heat waves in Decatur and how we can fix them so your house feels cool again.
5 Common Air Conditioning Repairs That Happen During Heat Waves
When temperatures soar, your air conditioning system is working harder than it does at any other time of the year. If a part is already weak or your AC unit hasn’t been running as efficiently as it should, a stretch of high outdoor temperatures is often enough to push it over the edge.
Here are some of the AC problems during heat wave Decatur, IN, residents need to know, what usually causes them, and how they’re typically repaired.
1. Capacitor Replacement for an Air Conditioner That Won’t Turn On
One of the most common summertime service calls is an air conditioner that suddenly won’t turn on. If you’re searching for “air conditioner not cooling during heat wave Decatur, IN”, a failed capacitor is often the reason. A capacitor is a small electrical component that gives the motors inside your AC unit the boost they need to start.
Every time your air conditioner cycles on, it relies on that extra burst of electricity. After thousands of starts over the years—and plenty of Indiana summer heat—the capacitor can eventually wear out and stop working.
The Solution: A technician will test the capacitor along with the rest of the electrical system to confirm the power problem. If it has failed, replacing it is usually a straightforward repair that can often be completed during the same visit.
2. Refrigerant Leak Repair for Warm Air Coming From the Vents
If your air conditioner is running but only blowing warm air, low refrigerant may be to blame. Refrigerant is the fluid that moves through your air conditioner carrying heat from inside your home to the outdoor unit, where it’s released outside.
When the system develops refrigerant leaks, there isn’t enough refrigerant to move that heat efficiently and produce enough cold air. It’s the reason why you’re looking up an “AC blowing warm air Decatur, IN” on your phone right now! The result is hot air, longer run times, and sometimes even ice forming on the indoor evaporator coil. Sound familiar?
The Solution: A technician will first locate the leak before making repairs. Once that’s done, the system is recharged with the correct amount of refrigerant, and the technician verifies that the air conditioning system is cooling properly again.
3. Blower or Airflow Repairs for an Air Conditioner That’s Running Too Much
During a heat wave, it’s normal for your air conditioner to run much longer than usual. Many systems run almost continuously during the hottest part of the day. But if your home never reaches the temperature you’ve set or can’t make the house much cooler, there’s likely another issue contributing to the problem.
When you want to know about your “AC running constantly Decatur, IN”, it often comes down to a dirty air filter. A dirty filter restricts airflow through the system. Over time, it can also allow dust to build up on the evaporator coil, making it even harder for your air conditioning system to cool efficiently. Blower problems or issues with the air ducts can have a similar effect.
The Solution: A technician will inspect the airflow throughout the system, check the filter, blower, evaporator coil, and ductwork, and identify what’s keeping the system from moving enough air. Once the restriction is corrected, the system can cool your home much more effectively.
4. Outdoor Coil Cleaning for an Air Conditioner That’s Struggling to Keep Up
Most homeowners think the outdoor unit creates the cool air, but that’s not actually what it does. Its job is to get rid of the heat that’s been removed from inside your home. During periods of intense heat, that becomes much more difficult. If the outdoor coil is covered with dirt, grass clippings, cottonwood, or leaves, it can’t release heat efficiently.
The entire AC system, especially the compressor, has to work harder during the cooling process, reducing efficiency and making it more difficult to keep up with the hottest afternoons.
The Solution: A technician will safely clean the outdoor coil, clear away debris around the unit, and inspect the fan and compressor to make sure heat can be released properly.
5. Condensate Drain Cleaning for Water Leaks and System Shutdowns
As your air conditioner cools your home, it also removes moisture from the air. That water has to go somewhere, so it drains away through a small pipe called the condensate drain. During hot, humid weather, algae and debris can build up inside that drain and clog it. When that happens, water may leak around the indoor unit, and many newer systems will automatically shut themselves off to help prevent water damage.
The Solution: A technician will clear the clogged drain line, flush it to restore proper drainage, check that water is flowing freely again, and make sure the safety switch is operating correctly before restarting the system.
The Longer You Wait, the Hotter It Gets
During periods of high temperatures, small issues can quickly turn into bigger ones because your HVAC system is already working as hard as it can. The longer you wait, the greater the chance of losing AC altogether—and open windows and ceiling fans aren’t going to do much when it’s in the 90s before lunch.
Calling at the first sign of trouble may help you avoid expensive repairs and higher energy bills. If you notice any of these warning signs, it’s time to have your central AC system checked out.
- Your thermostat says the house should be cool, but it still feels warmer than it should. (It’s worth checking your thermostat settings first, just to make sure nothing was changed accidentally.)
- The air coming from the vents feels weak or isn’t as cold as usual.
- Your air conditioner seems to run all day but never catches up.
- You hear banging, grinding, buzzing, squealing, or other unusual noises.
- You notice water pooling or dripping around the indoor unit.
- Your air conditioner keeps turning on and off, or it won’t start at all.
- Your energy bill suddenly jumps much higher than normal without a good explanation.
