High Heat in Richmond: What to Expect From Your AC (and When to Call for Help)

Written by TCMS | Jul 15, 2025 1:00:00 PM

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
