Installing a wall-mounted mini-split system is low-key. Your home won’t be ripped up because there are no ducts or air vents. Our technicians will skillfully install it by drilling small holes in the wall. These holes allow the indoor and outdoor units to be connected by refrigerant lines.

Furnace Installation

The age of your equipment is a key indicator when deciding whether to replace your system, but it’s not the only factor to consider: safety, frequency of repairs, quality of installation and improper sizing of your existing equipment are all reasons why you may need to replace your equipment. Also, new equipment is far more efficient than models purchased just 10 years ago – by as much as 60 percent.

What Our clients say

Helen J. - Altadena, CA


I just can't tell what a blessing Connor Air has been in my life. They put in a full house a/c/heating system in my home 13 years ago and have been there for great service ever since. Mr Connor was so helpful when I first got my system but what followed really surprised me by giving me the outstanding service I have received for for all these years. The ladies in the office and beyond nice I love talking with them. The service tec's are just so nice and helpful keeping my unit running great and I don't have to worry about my system I know it's well cared for and if I did need repairs they would do a great job at a fair price.
