Winter Services: Heating System Installation and Repair

Heating System Repair, Heating System Installation

Since 1972 from our home in Hazleton, SJ Kowalski Inc has helped keep our neighbors in northeastern Pennsylvania warm. Our professional team has unparalleled experience installing and servicing all types of heating systems including gas and oil furnaces, boilers, heat pumps, and mini-splits.

If you have an existing home or business, you probably have either a ducted system with a gas or oil furnace, or a boiler with baseboard radiators or radiant heat. If you are considering a new installation you have a number of system choices based on the system type, fuel, and features most closely meet your needs and budget.

Now well into our second generation, the Kowalski family has had close links to our community. We are members of the Great Hazleton Chamber of Commerce and have been members of the Better Business Bureau since 2006. We are more than proud of our A+ BBB rating.

We are both an authorized Trane Comfort Specialist, and a Diamond Elite Dealer for Mitsubishi. We have invested in our people and our business to ensure that we can offer you the latest and most efficient systems available.

SJ Kowalski Inc also offers 24 hour heat service for all heat systems regardless of brand. We strongly encourage proper heating system maintenance. A properly maintained system will be more efficient, more reliable, and will last longer. SJ Kowalski Inc offers our Comfort Club. It’s a great way for you to ensure that your system is inspected, cleaned, and maintained before each heating season to give you the peace of mind you need to stay comfortable though our long northeastern Pennsylvania winters.
