Frequently Asked
Questions.

Before you panic, check the 'Big Three':

1. The Air Filter: Is it clogged? A super dirty filter can shut down the system.
2. Thermostat Batteries: Are they dead? It happens to the best of us.
3. Circuit Breaker: Did it trip? Check your panel.

If those look good and it's still silent, the Llama is ready to help!

In Northeast Oklahoma, with our pollen and dust levels, we recommend checking them every 30 days and changing them at least every 90 days. If you have pets or live right on a dusty lake road, you might need to swap them out more often to keep your system breathing easy.

It could be a few things, like a dirty flame sensor (safety shutoff) or a pilot light issue if you have an older unit. Sometimes the burner just isn't igniting. Don't let it chill your bones—give us a shout and we'll diagnose it safely.

A little light frost in the winter is normal; your system has a built-in 'defrost mode' to melt it away periodically. However, if your unit looks like an igloo or a solid block of ice, that's not normal—you likely have an airflow problem or low refrigerant.

Usually, this is just a clogged condensate drain line. Dust and algae can build up over time, backing water up into the wall unit. It's a common 'drama' we can fix fast with a good flush and cleaning.

A hum usually means power is getting there, but a part isn't moving. It could be a failing capacitor (the battery that starts the motor) or the blower motor itself struggling. Better to catch it now before it stops completely!

Most likely dead batteries (an easy fix!) or a tripped float switch in your overflow drain pan. If new batteries don't work, check your drain line or give us a call.

Think of it as a lifeguard for your ceiling. It's a safety device that automatically stops your AC if the drain line gets clogged and water fills the emergency pan. This prevents water from overflowing and pulling down your ceiling drywall!

AC repair costs in the Grand Lake and Northeast Oklahoma area typically range from a flat-rate diagnostic fee to a few hundred dollars depending on the issue. At Cozy Llama, we provide upfront pricing before any work begins so there are never surprises. Common repairs like capacitor replacements or refrigerant top-offs are straightforward; a full system replacement is a bigger conversation we'll walk you through honestly.

Living near Grand Lake O' the Cherokees comes with unique HVAC challenges:

• Clogged condensate drain lines from high humidity near the lake
• Frozen heat pump coils during Northeast Oklahoma winters
• Dirty air filters from seasonal pollen and dusty gravel roads
• Power surges during spring storm season

A Llama Loyalty Club membership with seasonal tune-ups prevents most of these issues before they become expensive emergencies.
