These guys are THE BEST. I contacted Groundhog last summer when I decided to put central AC into my rental unit. They came highly recommended from a friend in the remodel/renovation industry. I called and set up an appointment to meet with Pat at the rental unit. He was on time and super nice. We booked the appointment for about a week later - the whole process was fast and painless. AFTER installation, I got a note from my HOA saying I couldn't have the unit where we placed it.(A different story entirely - I contacted them for the green light and never heard back, so I proceeded on my own.) I pleaded my case before the board, but they wouldn't let me keep it where it was. The team at Groundhog - especially Carrie and Heather - were so nice and supportive. They assured me they'd work with me until the HOA was satisfied. The board permitted me to leave the unit where it was over the holidays and have it moved in the spring. Well, due to multiple snow storms and a few complications with my tenant's schedule, we ended up not being able to get it moved until just a few days ago (May 3.) The team at Groundhog went above and beyond - they were friendly, professional, accommodating, and reasonably priced. They made a really frustrating situation that much better. I'd recommend them in a heartbeat. read more

I cannot tell you how much I appreciate Groundhog's prompt and professional service, especially given my unique situation of being in California and needing to have someone at my rental property to meet my another party to help. I am keeping your number and will absolutely be in touch when something comes up. read more

Whom you gonna call when your furnace kicks the bucket in the middle of a frigid night? Groundhog! This time, there was no resurrecting this old clunker of mine! After 24 years of service, she was DONE! I gave Groundhog a buzz before the chickens started to stir and by 6 AM I was breaking my piggy bank to scrape up for a brand spanking new unit. Before the kids were home from school, I was toasty and happy as if nothing ever happened. Groundhog was really easy and pleasant to work with from start to finish. I appreciate wonderful customer service and such quick response to what truly was a dire situation for me. This company delivers! Thanks to my friend Beard for the referral! read more

5 years ago, my furnace when out in the middle of November. I went with another company at first, they diddled around for a week, sent one tech out to tell me I needed a new furnace, took another week to send a salesman over who quote me an exorbitant price will pushing how they could finance and get my heat on that same day. I was on the phone to Groundhog before that loser's truck was out of my driveway. They had a guy out to do a quote the next day, and a few days later came during a blizzard and worked 12 hours straight to get my heat going. Could not ask for better service. This last week, a part on the furnace stopped working. I had a tech at my house within hours. He got the heat back on, showed me how the part was about to fail completely, got it covered by the manufacturer warrant, and had a quote for me in less than an hour. They ordered the part and were back in two days to install it, again in about an hour. They will always be my first phone call, and I do not hesitate to recommend them to anyone else. read more

Nathan (and others) from Groundhog heating have been phenomenal to work with! They have provided a number of services for us from minor house-calls to installing a full furnace system. Most recently, our heat went out on an extremely cold day and Nathan responded to the service call. He was at our house within 35 minutes and had the furnace back up and running in less than hour from my call. Nathan also spends the time educating me on how to trouble-shoot the furnace for future reference. In addition, their communication process is spot-on, even with text messaging with ETAs on their arrival. They make the whole service call process easily and friendly. I know my AC unit has limited time left and I will absolutely call Groundhog to replace the unit as they've built themselves as my one and only trusted adviser of HVAC needs. Dan read more

Groundhog heating is the best heating and cooling company we have ever used. Brooke and Zach, the technicians, were kind , knowledgeable, professional, and the best we have ever had. We are in our 70's and have lived in 5 states. Hands down the best we have ever had. Zach's assistant even took my trash out.. because it was sitting by the front door The bill was reasonable too. We have a big and complicated house with Nest Thermostats. We have air conditioning again Yah. read more

This review is long overdue but I want everyone to know what a great experience we had with this company. From the very beginning, they were helpful and courteous. Carrie helped book my appointment, answered my questions, and followed up with me after everything was done. The work was completed fast and they were very professional. We have already recommended them to several friends. Overall, great service. Thanks again! Kim B. read more

The team at Groundhog Heating & Air Conditioning were great to work with throughout the process, from the early conversations on what products would serve our needs best, through the meticulous install process, and the follow up conversations to make sure that everything was performing as expected. Their expertise and product knowledge is evident right from the start, and their willingness to answer all of our questions made us feel good about our choice of both product and install company. read more

We've used Groundhog for over 5 years both in Monument and now in Parker. Last year we had to get a new A/C unit. They installed it but it wasn't cooling well. They came and adjusted some things and it was fine until this summer. It froze up last week and they sent someone out right away. Zack was able to figure out the issue and added a couple features to the unit. It is working perfectly now and they didn't charge us a thing! They even gave us a coupon for future services. Carrie in the office is helpful and Zack really knows his stuff! Great customer service. read more

This company is simply the best! My air conditioner recently went out during the 90-100 degree weather streak we were having. I had 3 companies come out and all said I needed a new one. The first two technicians I did not like and I was then referred to Pat at Groundhog by some neighbors. He had a full schedule but managed to come out anyway the same day and replace my unit very quickly. Pat's prices were very fair and he was professional and timely. They run a nice family owned business. There are plenty if things I would've rather been spending my money on but they made it as painless as possible. Very trustworthy and I am so happy I have someone to call should I need help with an appliance down the road. They are now my new HVAC company. A+++!!! read more

Pat has saved us (on short notice) from freezing or melting on a few occasions and doing business with Groundhog is always affordable, easy and very pleasant. Great company! read more

Pat is beyond amazing. Love being able to support local business and being a veteran make it even better. He's on time, courteous, and knowledgeable and most importantly, he doesn't take you to the bank when it comes time to pay the bill. There is nobody else I would trust with my furnace, A/C, or installing a whole house humidifier. read more

Beware, they refuse to work with homeowners contrary to what their website states. Came to my house to do a quote, almost a week later, they refuse to send it over. Very rude on the phone! read more

Our 22 year old furnace and air conditioner needed to be replaced. We received quotes from several different companies, and Patrick and Carrie from Groundhog Heating were the most helpful and the most reasonably priced. I also felt the most comfortable with Patrick because he did a great job of explaining, in an understandable way, the cost-benefit analysis of the different energy efficiencies for the furnace and AC. He even recommended that we get a less expensive AC given our minimal AC use (we have a whole-house fan that works for most of the summer) and the average life expectancy of an AC unit. They arrived on time and installed a new American Standard furnace, air conditioner, and a humidifier in 1 day. They applied for the permits and will be arranging for them to be closed. They also cleaned up before they left. Finally, they found and helped us complete the energy rebate paperwork with our natural gas company (xcel energy), which should save us another $200. read more

Quick response, fair price. Great company to work with. Installed new furnace and thermostat.

Our furnace was going out intermittently and because of that, it was difficult to troubleshoot the issue. We had 2 different contractors from our home warranty company come out over 4 separate visits in an attempt to resolve the problem. Unfortunately, none of the contractors were able to fix the issue - during the three coldest weeks in Colorado this winter, our furnace would stop working. Finally, fed up with the home warranty's contractors, we got a referral from a friend for Pat from Groundhog Heating. We called him up and explained our situation. Although it was an extremely cold day and he had lots of other calls in that day, he made the time to come by and check on our furnace. He performed advanced diagnostic work on our furnace control system - far beyond the capabilities of the previous contractors that had come out - and informed us that he believed he found the issue and the entire control board needed to be replaced. Having already dealt with several botched attempts at fixing the problem, we went ahead and authorized Pat to perform the work, even though we had a home warranty service. We could not have been happier with our decision - Pat came back with the parts the next day, replaced the old with the new, and I'm so thrilled to say that after a 5th visit (and one supremely competent handyman) our furnace was fixed for good! Pat did an incredible job at a very difficult time for us - dealing not only with the freezing cold temperatures, but also with our frazzled nerves at so many failed attempts to fix it previously. I would absolutely recommend Pat's Groundhog Heating services for any furnace work that you may need - he's honest, punctual, and most importantly he really understands how heating systems work and makes sure to get the job done right. read more

I will call these guys again if I need to!! Fantastic assistance in getting our AC back up and running over a hot 4th of July weekend. Kari provided the best service and was awesome to work with. The repair was completed quickly and the technician was on time, professional and extremely reasonable for pricing! So glad I gave them a call. read more
