Your property has Mini-Split Heat Pumps (Wall Units)
Important: Mini-splits are high-efficiency heat pumps. In heating mode, the air feels lukewarm (not hot) because they work differently than traditional furnaces. This is normal! They're designed to run continuously at lower temperatures for maximum efficiency and comfort. It's best to leave them on rather than turning them on and off.
First, check the wall unit (indoor unit):
- Locate the remote control (usually mounted on wall near unit or in a drawer)
- Check if unit is powered on—look for lights on the display
- Verify mode is set correctly:
- Snowflake icon ❄️ = Cooling
- Sun icon ☀️ = Heating
- Fan icon = Fan only (no heating/cooling)
- Check temperature setting:
- Cooling: Set to 72°F or below
- Heating: Set to 68-70°F
- Make sure air vents on unit are clean and unobstructed
- Check if circuit breaker has tripped
- Wait 15-20 minutes for temperature to adjust before calling for service
If unit still doesn't work:
- Check the outdoor unit (condenser) - is it running? You should hear a fan
- Make sure outdoor unit isn't covered or blocked by debris
- Try turning the unit completely off, wait 5 minutes, then turn back on
For traditional central AC/heat (if applicable):
- Check thermostat display—is it lit? If not, try replacing batteries
- Verify thermostat is set to COOL or HEAT (not OFF or AUTO)
- Make sure temperature setting is appropriate
- Check your circuit breaker for tripped switches
- Look at air filter—if very dirty, replace it (filters in utility closet)
- For heating: check if pilot light is lit (if gas furnace)
