Our Core Principles

Harker Heating & Cooling is committed to one thing: You. Together, with our staff, we will deliver integrity, solutions, and the very best service possible to our customers. We pledge to all of our customers, partners, and staff that we will make every effort to satisfy your needs.

Customer Focus

We believe the customer is THE BOSS. If we don’t support the customer directly, we serve those that do. Customer service trumps everything.


We come to work each day ready to give it our best. We know what we need to do and we own it. We find out-of-the-box ways to solve complex challenges.


Trust and credibility are at the center of every business. We encourage everyone to speak freely and listen earnestly so that people and ideas thrive, while managing tough situations with courage and candor.


We believe that attitude is contagious. Embody the attitude you desire in others. A positive attitude gives you power over your circumstances instead of your circumstances having power over you.

Constant Improvement

Continuous improvement is better than delayed perfection. We believe that small, ongoing improvements can result in meaningful changes.

Passion For Winning

We have an unyielding drive to win, but always remain humble.
