Why won't my Daikin mini-split start cooling right away?
It may just be waiting. Daikin's operation manual says the compressor does not operate for about 3 minutes after the unit is started, as protection against frequent starting — wait 3 to 4 minutes before assuming a fault. If it still won't cool, check filters, mode and the breaker, then call a technician.
What maintenance does Daikin recommend?
Daikin recommends cleaning the air filters once every two weeks to prevent clogging and inefficient operation. In Florida's humidity, the coil, blower and drain need attention too — see cleaning & maintenance and leaking water.
Can Daikin help me troubleshoot over the phone?
Not with repairs. Daikin says homeowners need a licensed technician or dealer to diagnose the unit, because HVAC is a licensed industry and Daikin doesn't offer technical assistance to people who aren't licensed. Its owner support center has manuals and registration. To reach a technician who works on ductless systems near you, use our Florida mini-split referral line.
Bought your Daikin online?
Read the warranty carefully: Daikin states there is no warranty on equipment bought over the internet unless it is installed by a dealer following all applicable codes and licensing requirements. Florida licenses air-conditioning contractors, so ask any installer for their license number. See repair or replace if you're weighing a new system.
