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.

From commercial repairs to installations, our service technicians are trained to get the job right the first time. We take pride in our workmanship and strive to offer the best customer service. Let us take care of your commercial HVAC system so you can focus on your business.

Duct Cleaning Services

Regular duct cleaning reduces allergens and makes it easier to breathe in your home. Duct cleaning also removes any odors that may be due to pets and smoking. If your ducts are infested with rodents and insects, you should schedule a duct cleaning with Air King Inc. as soon as possible.

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!

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.

Professional

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.
