Summer Services: Air Conditioning System Installation and Repair

Cooling System Repair, A/C System Installation

Since 1972 from our home in Hazleton, SJ Kowalski Inc has helped keep our neighbors in northeastern Pennsylvania cool. Our professional team has unparalleled experience installing and servicing all types of air conditioning systems including air conditioners, mini-splits, and geothermal heat pumps.

If you have an existing home or business, you probably have either a ducted system with an air conditioner, or a heat pump. 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 your the latest and most efficient systems available.

SJ Kowalski Inc also offers 24 hour repair service for all cooling systems regardless of brand. We strongly encourage proper air conditioning 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 cooling season to give you the peace of mind you need to stay comfortable though our long northeastern Pennsylvania summer.
