Richmond summers aren’t just warm—they're sweltering. With temperatures regularly climbing into the 90s (and higher with humidity), your air conditioning system becomes more than a convenience—it’s a necessity. But how well should your AC *really* perform when the heat is relentless?

**What’s Normal for Your AC in Extreme Heat?**

When outdoor temps hit 90–100°F, your air conditioning system is working harder than ever. Here's what's considered normal behavior:

- **It may run continuously** during the hottest part of the day.
- **Your indoor temperature might hover around 75–78°F**, even if you’ve set it lower. Most systems are designed to cool your space by about 20 degrees from the outside temperature.
- **Humidity may increase slightly**, but a well-functioning system should still maintain decent moisture control.

**Signs Your AC May Be Struggling (and Needs Attention):**

If you're noticing these issues, it may be time for a checkup:

- **AC never reaches the thermostat setting**, even in the evening
- **Warm air coming from vents**
- **Unusual noises or weak airflow**
- **Skyrocketing energy bills**
- **Leaking around your indoor unit**

**How to Help Your System Handle the Heat**

Even if your AC is functioning properly, there are ways to give it a boost:

- **Change your filter** every 1–2 months
- **Keep blinds and curtains closed** during the day
- **Avoid using ovens and dryers during peak heat hours**
- **Use ceiling fans** to help circulate cool air

**When to Call a Professional**
