How often should evaporator coils be cleaned?

Evaporator coils should be cleaned every one to two years, with a yearly inspection. Homes with pets, heavy dust, or long run times often need cleaning every year.

What happens if you never clean your evaporator coil?

Cooling gets weak, run times stretch out, and energy bills climb. Ice can form on the coil, water can leak from the drain pan, and the compressor takes on strain it was not built for.

Can a dirty evaporator coil stop my AC from cooling?

Yes. A coated coil cannot absorb heat from your air. The system keeps running, but the house never reaches the temperature you set.

Why is there ice on my indoor AC unit?

Ice usually means airflow across the coil has dropped too far. A dirty coil or a clogged filter is the common cause. Shut the system off and let it thaw before running it again.

How do I keep my evaporator coil clean between visits?

Change your air filter on schedule. Keep the vents open and the area around the indoor unit clear. That handles most of the dirt before it ever reaches the coil.

Humidity Clues in Waterstone Homes, and What They Usually Mean

Too much moisture inside your home often shows up before the heat does. Use this table to match what you notice with what it often means.

What you notice	What it often means	What to do
Rooms feel sticky at the set temperature	The AC isn’t pulling out enough moisture	Check the fan setting, then call us
A musty smell near the vents	Moisture building up in the system	Call us to check the coil and drain
Condensation on windows or vents	High indoor humidity	Note where it forms, then call us
The AC turns on and off quickly	Short cycling, so less moisture is removed	Call us to check the system
Water around the indoor unit	A clogged drain line or pan	Turn the AC off and call us
The fan runs all the time	The fan is set to “On”	Switch it to “Auto”

How Your AC Pulls Moisture Out of the Air

As warm, damp air passes over your AC’s cold indoor coil, moisture collects on the coil. That water then drips into a pan and flows out through a drain line. On humid North Texas days, this step matters as much as cooling.

A few problems can get in the way:

A dirty coil or filter slows airflow and lets less moisture collect.
A fan set to “On” can blow moisture from the wet coil back into your home.
Short cycling stops the AC before it has time to remove much moisture.
A clogged drain traps water that should leave the system.

High indoor humidity can lead to musty smells and mold over time. When you call us, we check the coil, the drain, the fan settings and how long your system runs. You can see all of our air conditioning services for Frisco homes in one place.
