Mild winter
Heating season is when CO alarms matter most.
When to call a pro: Replace any alarm past the date on the back.
Heating moves dust through the house too.
Thick ice that stays means something is wrong.
When to call a pro: Get a technician to check.
Late winter
Technicians get busy once the heat arrives.
The unit needs open air to work well.
Blocked vents upset airflow.
Spring
A clean filter keeps air moving. See <a href="/guides/how-often-to-change-your-ac-filter">how often to change your AC filter</a>.
Better to find a problem now than in July.
Spring growth is fast here.
Spring storms
Branches and debris can bend fins and block airflow.
When to call a pro: Do not open the unit.
Spring humidity means the AC removes lots of water.
Leaks start small.
Getting hot
Cooling season is here.
Fans let you feel cooler without lowering the thermostat as much.
Less heat in means less work for the AC.
Storm season begins
The Atlantic hurricane season runs from June 1 to November 30.
It gives the system a moment as power comes back.
When to call a pro: If it will not restart, check the breaker, then call a technician.
Filters clog fastest in summer.
Peak heat
The AC cools at the same speed either way.
Problems show up when the system works hardest.
When to call a pro: Turn it off and get help if it ices up.
Clean coils move heat better.
When to call a pro: Do not use a pressure washer.
Late summer
Mid-summer is when filters clog fastest.
It can be an early sign the system is struggling.
Late-summer humidity keeps drains busy.
Storm season continues
Debris blocks airflow.
Note problems now and book repairs before next summer.
Storms can still knock out power.
Fall
A check makes sure it runs safely when you need it.
When to call a pro: Gas appliances need a qualified technician.
A twice-a-year habit keeps them working.
A fresh filter for the switch to heating.
Leaf season
Fall leaves pile up fast under tall trees.
That gently pushes warm air down.
It should fade quickly; a strong smell needs a technician.
Cold snaps
Freezes are not frequent here, but unprotected pipes can split.
Space heaters are a common cause of winter fires.
When to call a pro: Plug them straight into the wall.
The system may be running more on cold days.
