Switching Over to A/C for Hotter Virginia Days

Your Guide from C.B. Lucas Company, Inc. to Stay Cool, Comfortable, and Stress-Free

When Virginia starts turning up the heat, your home’s comfort depends on one thing working exactly right. Your air conditioning system. Whether you’re in Woodbridge, Stafford, Fredericksburg, or right here in Northern Virginia, those warm spring days can quickly turn into hot, humid afternoons that demand reliable cooling.

At C.B. Lucas Company, Inc., we believe in fixing it, not upselling it. So here’s a straightforward, homeowner-friendly guide to switching over to A/C the right way.

When Should You Switch to A/C in Virginia?

In our area, most homeowners make the switch sometime between late April and early May. But the real answer depends on temperature trends, not the calendar.

Time to switch when:

• Daytime temps consistently hit 75 to 80 degrees

• Humidity starts creeping up

• Your home feels stuffy even with windows open

Virginia humidity is no joke. Even if it doesn’t feel scorching yet, your A/C helps control

moisture, which keeps your home more comfortable and protects things like wood floors and trim.

Step-by-Step: How to Switch Your System Over

1. Change Your Air Filter

Your system just worked all winter. Start fresh.

• Replace with the correct size filter

• Choose a basic pleated filter for best airflow

• Avoid overly restrictive “allergy” filters unless recommended

A clogged filter is one of the biggest reasons A/C systems struggle or freeze up.

2. Flip Your Thermostat to “Cool”

Seems obvious, but it matters.

• Set your thermostat to cool mode

• Start with a reasonable temperature like 72 to 74

• If you have a smart thermostat, double check schedules

If you’re using something like a Nest Thermostat or similar, make sure it didn’t carry over a heating schedule.

3. Check Your Outdoor Unit

Your condenser needs to breathe.

• Clear leaves, pollen, and debris

• Make sure at least 1 to 2 feet of open space around it

• Do not spray aggressively with a pressure washer

4. Test the System Early

Don’t wait until the first 90 degree day.

Turn it on and watch for:

• Cool air coming from vents within a few minutes

• Normal airflow (not weak or barely there)

• No strange smells or loud noises

If something feels off, it’s better to catch it now than during a heatwave.

Common Problems We See Every Spring

At C.B. Lucas Company, Inc., these are the most common early-season A/C issues:

• Systems not cooling due to low refrigerant

• Frozen coils from dirty filters or airflow issues

• Outdoor units clogged with debris

• Thermostat settings not switched correctly

• Capacitors failing after sitting all winter

The good news. Most of these are quick fixes when caught early.

Should You Schedule a Spring A/C Check?

Short answer. Yes.

A professional tune-up helps:

• Catch small issues before they turn into expensive repairs

• Improve efficiency and lower your electric bill

• Extend the life of your system

And more importantly, it gives you peace of mind before Virginia heat really kicks in.
