Hope all is well with you. It’s Super Sunday here. I don’t know about you, but with no Rams, Chiefs or (likely) good halftime show, the commercials better be good. ...


Why Harster?

“A quick letter to let you know how pleased I am with the level of competence from both Jeff in March and today with Richard. These are both exceptional staff members who know how to hunt down a problem and effect the absolute right fix. I was self-employed for 22 years, and before that Executive Vice President of a chain of fourteen high-end retail stores in St. Louis. Customer service was my livelihood. I had a loyalty to Galmiche and Sons Heating & Cooling for almost three decades. After a disheartening experience with the company, I sought another service provider. I remembered often seeing Harster trucks, and then remembered something: almost every single person driving those trucks was an older man! To me, that meant seasoned people…capable of customer care and technical know-how. Both Richard and Jeff were simply terrific. Kudos to you and your company for a policy of hiring the best, and keeping them!”
