Ductless Air Conditioning

Ductless air conditioning is a great cooling alternative if you want to save energy. Ductless systems are easy to install because a technician only needs to drill a three-inch hole into a wall to install the unit. Let us help you bring climate control to a home addition or guesthouse with ductless air conditioning.

Highly Recommend

We called Air King to repair our furnace in the middle of a polar vortex, and they came out in 2 hours. They worked with us to get our older model up and running again for a reasonable price! Highly recommend their service!

Very Pleased

I am very pleased with the service I received from Air King. My furnace was not working properly. Jeremy T. was friendly and professional and set about to discover and correct the problem(s), which he did in an efficient manner.
-Peg W.


Jeremy was very professional. He explained everything that he was doing and why he was doing it while working in my furnace. He had everything back up and running in short order. 5/5 will call for service again, if needed.
