When You Want Comfort… You Want Kalins!

Since 1921, Kalins has accumulated years of experience in AC service, repair, and installation. We have extensive industry knowledge that ensures your service will be done right the first time. Call us 24/7 for any emergency repairs when your air conditioning unit breaks down. We have fully-stocked service and maintenance vehicles along with highly-trained service technicians, and we can service any make or model.

However, before that emergency repair happens, we highly recommend a Precision AC Tune-Up. Most repair calls could be avoided with regular air conditioning service and maintenance. All manufacturers recommend an annual tune-up preventing costly breakdowns, making sure it is operating safely thus maximizing your AC's efficiency. In the event an air conditioning replacement system is needed, as a Premier Lennox® dealer, we offer the most reliable and efficient air conditioning equipment. Call us today!
