Can I DIY this?
30-second readiness check
Comfortable drilling a 3" hole through your exterior wall?
Required to pass the line set and drain to the outside.
Can you get a helper to lift the outdoor unit (~80–120 lbs)?
Two people makes condenser placement much safer.
OK working on a ladder to mount the indoor head?
Indoor unit mounts high on the wall — usually 7–8 ft.
Electrician lined up for the dedicated circuit (or already have one)?
Panel work should be done by a licensed electrician if you're not sure.

Permits — Tampa Bay
Most Hillsborough, Pinellas, and Pasco County installations require an electrical permit for a new dedicated AC circuit — even DIY. Energy Whisperer pulls permits on professional installs; DIY customers should check with their county building department or call us for guidance.
Tip: A quick call to your county building dept. before you buy can save a headache on inspection day.
