Daikin DX4SE


Daikin DX4SE

Whole House Air Conditioner

When properly matched and installed, your DX4SE Air Conditioner offers up to 15 SEER energy-efficient performance. The higher the SEER, the greater the efficiency — and the lower the operating cost compared to lower SEER units. In many applications, the efficiency of your DX14SA can be enhanced by using it in conjunction with a Daikin brand gas furnace. This unit features a powder-paint finish over heavy-gauge galvanized steel that provides premium durability and excellent UV protection.

What Our Customers Say About Us

"The guys were very friendly. They took lots of care and attention when removing the old furnace and replacing it with the new one to not damage anything along the way. Once finished they took the time to explain the operation and go through any questions we had. I would definitely use them again."

- Kyle J.


"This review is for Noel who came to my home to see why our electric air cleaner was not working. He was punctual and super friendly. Found the problem within 15 minutes. Had the part ordered, and 9 days later it literally only took him 3 minutes to replace it for us!"

- Joy H.


"Booking an appointment for a furnace checkup was a very quick and simple phone call. The technician was on time as promised, very knowledgeable and professional. It gave us piece of mind that our 10 year old furnace was in good working order."
