Opening Up a Seasonal Home: Ducts and Dryer Vent Checks

Plenty of homes on Amelia Island and across Nassau County sit empty for part of the year. Owners split time with another house up north, travel for work or leave a beach place closed between visits. When you come back, it's natural to open the windows, start the AC and get on with the week. A few checks first can save you a stuffy house, a strained system or a dryer that won't dry.

Here's a simple routine for reopening a seasonal home around Fernandina Beach.

Before you leave: set the house up well

The best reopening starts at the last closing. If the house will be empty for weeks or months:

• Don't shut the AC off completely. A humid, closed-up house can develop musty odors fast. Many owners set the thermostat to a moderate temperature or use a humidity setting if the system has one. Ask your HVAC contractor what is right for your equipment.
• Put in a fresh filter so the system isn't pulling air through a dirty one for months.
• Run a final load of laundry, then clean the lint screen, and leave the dryer door slightly open.
• Close blinds on sunny sides to reduce the load on the system.
• Make sure exterior vent caps close so birds, rodents and insects can't move in while you're gone.

Step one when you return: walk around outside

Before you power anything up, take five minutes outdoors:

• Look at the outdoor AC unit. Clear leaves, palm fronds and sand that drifted against it.
• Check the dryer vent hood. A flap stuck open is an invitation to nesting birds or wasps. A flap stuck shut means lint will back up.
• Glance at bathroom and kitchen exhaust caps for the same problems.

If you see a nest, don't run the dryer until the vent has been cleared.

Step two: the filter and the registers

Open the filter slot or return grille and look at the filter. Even in an empty house, a running system pulls in dust. If it's gray, replace it.

Then walk through the house and look at the supply registers:

• Fine dust ringing the grille usually means buildup inside the run.
• Dark spots around a register in a humid month can be condensation. Note it and ask your HVAC contractor to check the system's humidity control.
• A smell when the air starts up, musty or stale, tells you something inside the system needs attention.

If you see growth, call an HVAC contractor to look at the coil and drain pan, and a mold professional if needed.

Step three: give the system a little time

Start the AC, close the windows and let it run a full cycle. A house that sat closed can take a while to pull humidity down. Opening every window for a sea breeze feels nice, but it lets more moist air in and makes the system work harder once you close up again.

When it makes sense to clean the ducts

Coming back to a seasonal home doesn't automatically mean it needs duct cleaning. Consider it when:

• You see dust blowing from registers when the system kicks on
• The return is caked even after a filter change
• The house was renovated, painted or re-floored while you were away
• Pests got into the attic or crawlspace
• You just bought the property and don't know its history

Our air duct cleaning is $199 for up to 10 vents, plus $29 for each extra vent. For heavy buildup, deep duct cleaning is $59.99 per vent.

The dryer vent after a long break

A dryer that sat idle for months can surprise you. Lint left in the duct can settle and pack in humid air, and anything that nested in the vent while you were gone blocks the flow. Signs to look for on your first loads:

• Clothes still damp after a normal cycle
• The laundry room feels hot or humid
• A burning or musty smell when the dryer runs
• The outside flap doesn't open when the dryer is on

Dryer vent cleaning is $99 for up to 10 feet, plus $15 per additional foot. If you rent the home out between your own stays, a yearly vent cleaning is an easy item to add to your maintenance calendar.
