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
