    Our Story

    When I, Patrick Lohr, started Groundhog Heating & Air Conditioning, I made a decision to be a tradesman and not a salesman. As a result, my business grew by word of mouth. I was the one who answered the calls, visited with all potential customers, did all the service, and installed all the products.

    It must have worked because the amount of customers has grown year after year. Because of this fast growth, I reluctantly started looking for my first employees, searching for people who had the same caring pride that I have. I want to be proud of the people that I put in your home to take care of your HVAC, indoor air quality, and water heater needs, and have built a reputable team.

    I am happy to say that all of our certified technicians are knowledgeable, polite, and highly experienced. Everyone is also drug tested, background checked, and receives ongoing training.

    We look forward to being your chosen Parker HVAC contractor. I want to personally thank you in advance for your business and ensure you that all of my customers are a priority to me.
