Vacation Season Is Almost Here: Don’t Leave Your HVAC System Unchecked

Memorial Day weekend has officially come and gone, which means summer is no longer waiting quietly in the wings. Across Hampton Roads, many families already took their first road trip or even first long weekend getaway of the season. Coolers were packed. Suitcases were zipped. Traffic on I-64 became its annual endurance sport.

And now the official summer travel season is almost here.

While homeowners are busy planning vacations, there is one thing that often gets overlooked until it becomes a sweaty, humid problem waiting back at home: the HVAC system.

If you have not checked your AC system yet this season, now is the time.

Why Your HVAC System Still Matters When You’re Away

A lot of homeowners assume that if nobody is home, the air conditioning system can simply be ignored until they return. But during Virginia summers, your HVAC system does much more than cool the house.

It also helps control indoor humidity.

Without regular cooling cycles and airflow, humidity levels inside the home can climb quickly, especially during those classic Hampton Roads stretches where the air feels like warm soup with opinions.

Excess humidity can contribute to:

• Musty odors
• Damp indoor air
• Warped wood flooring or furniture
• Poor indoor air quality
• Mold and mildew growth in severe situations

That is why completely shutting your system off while traveling is usually not recommended.

What Temperature Should You Leave Your Thermostat on?

Most HVAC professionals recommend setting your thermostat somewhere between 78 and 82 degrees while you are away during the summer months.

This helps:

• Reduce unnecessary energy usage
• Maintain humidity control
• Prevent excessive indoor heat buildup
• Protect electronics, plants, pets, and other temperature-sensitive items

If your home has a smart thermostat, even better. Remote access can give homeowners peace of mind while traveling and allow quick adjustments if temperatures spike unexpectedly.

Why Older HVAC Systems Struggle During Early Summer

If your system is over 10 years old, the transition into summer is often when hidden problems begin to surface.

Spring weather tends to be forgiving. But once temperatures and humidity climb, aging systems suddenly have to work much harder and much longer.

That can lead to:

• Longer cooling cycles
• Weak airflow
• Electrical component failures
• Refrigerant issues
• Humidity problems indoors
• Higher utility bills

And unfortunately, HVAC systems have a remarkable talent for waiting until you are two states away holding a beach chair and a hot dog before deciding they no longer wish to participate.

Simple Things Homeowners Should Still Check Before Leaving

At this point, we know some of these reminders may sound familiar. We talk about filters, airflow, and outdoor units a lot. But honestly? That is because these simple maintenance items truly matter. They are easy to overlook, yet they can make a major difference in system performance and efficiency.

Sometimes the basics deserve an encore.

 

Change the Air Filter

A clogged filter restricts airflow and forces your system to work harder during the hottest months of the year.

Clear Around the Outdoor Unit

Grass, weeds, leaves, and overgrown shrubs can restrict airflow around your outdoor system. Give it at least two feet of breathing room.

Check Air Vents and Returns

Make sure furniture, rugs, curtains, or storage bins are not blocking airflow throughout the home.

Test the System Before You Leave

Do not wait until the night before vacation to discover your AC is making a sound that resembles a shopping cart full of silverware rolling down a staircase.

Why Late May and Early June Are the Best Times for an HVAC Tune-Up

Once the first major heatwave hits, HVAC companies across Hampton Roads become extremely busy with emergency service calls and breakdowns.

Scheduling service before peak summer demand arrives helps homeowners:

• Catch small problems early
• Improve cooling performance
• Lower the risk of breakdowns
• Avoid long peak-season wait times
• Keep energy bills more manageable

It is also a smart time to explore replacement options if your current system is aging, inefficient, or struggling to keep up already.

 

Start Summer Without HVAC Surprises

Summer vacations should create memories about sunsets, cookouts, and beach photos nobody asked to be tagged in. Not emergency HVAC breakdowns.

If you have not checked your AC system yet this season, now is the perfect time to take care of it before the real summer heat settles into Hampton Roads for good.

And yes, we know we keep talking about tune-ups, filters, and airflow.

That is because they work. Every single year.
