Our Story
When I, Patrick Lohr, started Groundhog Heating & Air Conditioning, I made a decision to be a tradesman, not a salesman. By doing so I let my business grow 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 since I went out on my own in 2010, the amount of customers has grown each year. Because of this, I reluctantly started looking for my first employees, searching for people who have 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 needs, and have built a reputable team.

All of our technicians are drug tested, background checked, fully certified, and highly trained.

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

I will give you the honest information I have, and make it a point to never “sell” you a product or service that you do not need.

We have an A+ Rating with the Better Business Bureau and are proud to serve Castle Rock and the surrounding areas.

Groundhog Heating & Air Conditioning received the 2017 Castle Rock Small Business Excellence Award in the Heating & Air Conditioning (HVAC) category (for the fourth year)! Thank you to all our loyal customers who have nominated us for this award. It is an absolute pleasure serving you!

Why is Groundhog Heating & Air Conditioning your company name? My two sons and myself were all born on Groundhog’s Day, February 2nd. As a symbol of both spring and winter, it’s no wonder that our family is involved in the heating and cooling business. I guess you can call it fate.
