When You Want Comfort… You Want Kalins!

Since 1921, Kalins has accumulated years of experience in heating 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 heating system 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 Tune-Up. Most repair calls could be avoided with regular HVAC service and maintenance. All manufacturers recommend an annual tune-up preventing costly breakdowns, making sure it is operating safely thus maximizing your HVAC system's efficiency. In the event a system replacement is needed, as a Premier Lennox® dealer, we offer the most reliable and efficient heating & air conditioning equipment. Call us today!
