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.
