“Oh boy the furnace is out in January in Missouri!! We called Harster Heating and Air Conditioning . They were at our home that morning to get us back in business . Thank goodness because it was cold outside. The technician was very knowledgable and professional and resolved the issue that morning. We have a sense of security knowing Harster is on our speed dial :)”

“We have used Hoffmann Brothers multiple times at our prior and current home and they have been very professional and always do an excellent job. They also solved a problem with our prior home's air conditioner that others could not fix. I would highly recommend Hoffmann Brothers.”

Heating & Air Conditioning Contractors in O'Fallon, IL
“I have use this company on two separate occasions and they perform exceptionally. The company replacement my 29 year old furnace and air conditioner in a one day without a hitch last year. They made sure everything was running and taught me how to use my new digital thermostate.
The second occasion is when my Condominimum Clubhouse's water pipes frozen and broke recently. There was major damage throughout the clubhouse including the furnance shorting out. Guarantee was there right away when the Board called to check out the furnance and then to give an estimate for a new furnace within a couple of days. The funace has just been replaced without a hitch and the technician was crawling out of the crawl space when I walked in to check on him. He still had a smile on his face. It was really cold that day but he did not think about and got to work right away. He also made some suggestion to help with keeping the crawl space warmer. I would recommend them to anyone.”
