Notice the symptoms
Is the air warm? Is one room different? Is the system cycling or making a new sound? Note when it started.
HOMEOWNER GUIDE
A little context helps.
You do not need to diagnose the problem. A few simple observations can help us prepare.
Check the visible settings
If it is safe, look at the thermostat mode and temperature setting. Do not remove wiring or electrical covers.
Know your filter
If the filter is safely accessible, note its size and when it was last changed. Follow equipment instructions for replacement.
Make room for the visit
Keep pets secure and provide safe access to the thermostat and equipment. Let us know about access limitations in advance.
Share the equipment details
A photo of the accessible make and model label can help. Never climb or open a panel to obtain it.
Put safety first
Do not work on electrical components, refrigerant lines, or moving parts. Smoke, sparking, or an immediate hazard calls for emergency assistance.
