Add to your system
Most installs need A line set kit, and a pad or wall bracket. I check what you have at the estimate visit.
Nice to have Optional upgrades.
Warranty plans JB extended labor coverage, optional.
Without my professional installation there is no warranty from me, and a manufacturer can deny its warranty when the equipment is not installed by a licensed HVAC contractor.
Federal EPA Section 608 rules require an EPA certified technician to handle the refrigerant in this equipment. To buy equipment only, I need a copy of your EPA 608 certification, or the certification of the technician installing it.
Your size and final price are confirmed in writing after the load calculation, before anything is ordered.

- AHRI certificate

How I size a mini split
I run a room-by-room load calculation: I measure the room, look at windows, insulation and which way it faces, and size the head from that math. A head that’s too big short-cycles and leaves the room clammy, and one that’s too small runs all day. You see the final price in writing before anything is ordered.
Paying for it
Ways to pay: cash or check (about 10% off every price), credit cards, and financing through Hearth, Wisetack, JB Financing, Klarna, Synchrony and Wells Fargo. Cash is king, and I take cards too. Hearth, Wisetack, Klarna and JB Financing check offers with a soft credit pull, so looking won’t touch your score. Hearth works with credit scores as low as 550. Subject to credit approval.
Questions about this system
How much does a Daikin Oterra Cooling Only mini split cost in Kingfisher Oklahoma?
Pick a size above. The smallest starts at $2,990 for the equipment, and my professional installation is $2,220.
Do I need more than one head?
One head handles one room or open area. For several rooms, look at the multi-zone builder, where one outdoor unit runs a head in each room.
What warranty comes with it?
12-year parts when registered within 60 days (5 years if not, and 5 years on commercial jobs). Parts only, not labor. You register it for the longer parts coverage, and my post-install email sends you the link. My 1-year labor warranty covers the installation.
Can I buy the equipment only?
Equipment only is available if you’d rather. Refrigerant-charged equipment has to be installed by an EPA Section 608 certified technician, the manufacturer’s warranty has to be registered on time and covers parts, not labor, and equipment is ordered for your job, so ask me about returns before you buy.
Can I finance it?
Ways to pay: cash or check (about 10% off every price), credit cards, and financing through Hearth, Wisetack, JB Financing, Klarna, Synchrony and Wells Fargo. Cash is king, and I take cards too. Hearth, Wisetack, Klarna and JB Financing check offers with a soft credit pull, so looking won’t touch your score. Hearth works with credit scores as low as 550. Subject to credit approval.
