Richmond’s heat waves can push your air conditioner to the limit. Weather can impact your AC, if you’re AC is struggling with heat waves, it’s time to take action before it gets worse. If your system is running nonstop and still not cooling well, it’s time to take a closer look, starting with the simple stuff.
You don’t always need a full replacement, but you do need to know what to look for. In fact, there’s many things your HVAC should be looking for to fix your AC.
Step 1: Rule Out the Simple Stuff
Before calling in a professional, double-check the basics. It sounds obvious, but small issues can cause big problems in a heat wave.
- Make sure your thermostat is set to “cool” and not just “fan”
- Replace your air filter if it looks dirty or hasn’t been changed in a while
- Open all supply and return vents (even in unused rooms)
- Keep windows and exterior doors shut during the hottest parts of the day
- Clear debris from around your outdoor unit to improve airflow
If none of those changes help, there’s probably something going on inside the system.
Step 2: Pay Attention to What Your AC Is Telling You
Air conditioners tend to give off warning signs when something’s wrong. You might hear new noises, feel weak airflow, or notice that the air isn’t as cool as it used to be.
Keep an eye out for these signs:
- Ice forming on the refrigerant lines or indoor unit
- A spike in your energy bill without a change in usage
- Frequent on/off cycling
- Warm air blowing from the vents
- A musty or burning smell while the system is running
If you notice one or more of these, it’s important not to ignore them. For example, ice buildup might seem like a cooling issue, but it usually means restricted airflow or low refrigerant, and running the system like that can cause long-term damage.
Short cycling can signal electrical problems or issues with the thermostat or compressor. A climbing energy bill usually means your system is running too often or too long to achieve the same result, which adds wear and tear over time.

Step 3: Consider the Impact of Richmond’s Climate
If humidity keeps building up, your system may not be able to pull enough moisture from the air to maintain comfort. That can make your home feel warmer than it is, even with the AC running full-time. If you’re noticing sticky air or foggy windows, those are signs your system needs attention.
Sometimes it’s a matter of maintenance. Other times, your system may just not be sized properly for your home. A quick inspection can confirm that.
