Killian came out same day and diagnosed the problem quickly. Gave us a fair price upfront and had it fixed in under two hours. Honest and professional—exactly what you want from an AC company.
Our AC died on a Saturday night in July. Called Killian's and a tech was at our door within the hour. They truly mean 24/7 service. Can't recommend them enough.
Had a full system installed—Carrier unit, new ductwork, the works. The crew was neat, professional, and finished ahead of schedule. The financing made it painless.
