Richmond is no stranger to hot summers, but when temperatures soar into the high 90’s or triple digits, even the best air conditioning systems can start to feel the strain.
As we enter the cooling season, it’s important to understand how outdoor temperature affect air conditioning system performance, especially during periods of extreme heat.
Here’s What You Need to Know
AC Units Have Limits
Most residential air conditioning systems are designed to operate efficiently up to 95°F. During this time, indoor temperatures of 78-80°F are typical, even when the system is running nonstop.
What Happens Over 100°F?
System efficiency begins to drop. Your AC works harder, consumes more energy, and may not keep your home as cool as you’d expect. It’s not broken – it’s doing the best it can with extreme outdoor conditions.
The 20-Degree Rule
A good rule of thumb: avoid setting your thermostat more than 20 degrees lower than the outdoor temperature. If it’s 100°F outside, aim for 80°F inside. Going lower can overwork your system and cause long-term issues.
Maintenance Matters
Regular HVAC maintenance ensures your system is running at its highest possible efficiency. Clean filters, proper refrigerant levels, and healthy coils all play a role.
Fun Fact!
Commercial systems are designed to handle a bit more – up to 105°F – but even they can struggle during prolonged heatwaves.
