How to Tell If Your AC Needs Repairs Before Summer Starts

Posted on May 23, 2025 | Air Conditioning

There’s something about the lead-up to summer that makes the calendar feel like it’s moving faster. Between travel plans, yard projects, and weekend get-togethers, it’s easy to let some things slip by. But before the season hits full stride, it’s smart to take stock of your home, especially your air conditioning system.

Your AC will be doing the heavy lifting once the temperatures rise. Taking a few minutes now to check in on it can mean the difference between a smooth, cool summer and an inconvenient breakdown during a heat wave. Knowing how to tell if your AC needs repairs before summer starts can help you stay ahead of issues and avoid surprise repairs when the heat is at its worst.

Signs Your AC Needs Repair Before Summer

Understanding how to tell if your AC needs repairs before summer starts can save you from unexpected failures and high energy bills. Here are some common signs your AC needs repair before summer:

1. The Airflow Feels Weak or Warm

One of the easiest ways to spot an issue is simply by feeling the air coming out of your vents. If the airflow is weak or not as cool as it used to be, that’s something you shouldn’t ignore.

This might mean there’s a problem with the compressor, or possibly a blockage in the duct system. In some cases, it could be as simple as a dirty filter. But in other instances, you might be dealing with a more serious issue affecting airflow and system efficiency.

Remember: Poor airflow can also affect your home’s overall comfort. Rooms might cool unevenly, leaving some areas hot and stuffy, especially during a heat wave.

2. Strange Noises Are a Red Flag

Your air conditioner shouldn’t sound like it’s working overtime in a factory. Grinding, banging, buzzing, or screeching sounds typically indicate something is off. These noises could mean parts are loose, components are wearing out, or internal damage is building up.

If your system is louder than usual, don’t wait for the noise to go away. Strange sounds are one of the more obvious signs your AC needs repair before summer, and ignoring them could turn a minor fix into a more expensive problem.

3. Something Smells Off

When your air conditioning unit kicks on, it shouldn’t come with an odor. Musty smells might be a sign of mildew or mold growing in the ductwork or near the evaporator coils — usually caused by moisture and poor drainage.

Burning or electrical smells, on the other hand, can be more serious. These odors might suggest problems with electrical wiring or overheating components, which can be a safety concern if left unchecked.

Odors aren’t just unpleasant. They affect the indoor air quality in your home, which matters for everyone, especially kids or anyone with allergies.

4. Your AC Is Turning On and Off Too Often

AC units are designed to cycle on and off to maintain the set temperature. But if it seems like your system is constantly powering up and shutting down without running a full cycle, that’s something worth paying attention to.

This short-cycling behavior can be caused by issues with the thermostat, refrigerant levels, or even an incorrectly sized unit. Not only does this put extra wear and tear on the system, but it also drives up energy use without cooling your home well.

5. Higher Bills Without a Clear Reason

If your energy bill is creeping up but your usage hasn’t changed, your AC might be the reason. As air conditioning systems age or develop problems, they become less efficient. The system works harder for longer periods to get the same job done.

Common culprits behind high energy bills include dirty coils, low refrigerant, and clogged filters. These things are easy to miss if you haven’t done routine maintenance. Keeping an eye on your utility bills is a practical way to spot hidden issues before they turn into major repairs.

How Do I Check My AC Before Summer?

Before the summer heat sets in, it’s wise to perform some basic checks on your air conditioning system:

  • Inspect and Replace Air Filters: Dirty filters can restrict airflow and reduce efficiency.
  • Clean Around the Outdoor Unit: Remove any debris, leaves, or plants that might obstruct airflow.
  • Check Thermostat Settings: Make sure your thermostat is set to cooling mode and functioning correctly.
  • Listen for Unusual Noises: Turn on your AC and listen for strange sounds that could indicate issues.
  • Schedule a Professional Inspection: Having a technician examine your system can help identify and fix problems before they escalate.

Key Takeaways for a Trouble-Free Summer

Knowing how to tell if your AC needs repairs before summer starts can make all the difference when it comes to staying cool and avoiding mid-season headaches. Watch for weak airflow, unusual sounds, musty smells, short cycling, and rising energy bills. These are all signs your AC needs repair before summer sets in.

Running simple checks now, like cleaning the unit, changing the filter, and testing the thermostat, can help you spot trouble early.

“I would choose them again and again.”

Pasterkamp has installed heating and air conditioning systems in two of our Colorado homes. In both cases, the systems have worked flawlessly. This company is a Colorado institution. I would choose them again and again.

“James really worked hard to find a solution and I really appreciate his efforts.”

Both Teresa when I called to set up service, and James who came out to check our unit were very polite and friendly. James really worked hard to find a solution and I really appreciate his efforts. We finally got our AC working. I would very much recommend these guys. Thanks much.

“I was happy to speak to someone who really knows the products and tells you what you need and didn’t try to upsell me.”

Brandon was very easy to speak to, he told me exactly what will happen and when. I have already given my sister Pasterkamp's number! I was happy to speak to someone who really knows the products and tells you what you need and didn't try to upsell me. I will always use Pasterkamp from now on!! I am getting a furnace that's the right size for my house and a heat pump installed
