I was able to follow his driving position with my smartphone. Technician was very knowledgeable and did a thorough job. I would recommend this company for heating and cooling systems.

They are very efficient, always on time and affordable.

My condenser stopped working last night, I know enough about electrical to be dangerous, I checked out a few things myself but hit a spot where I was out of ideas. I called Groundhog at 11am and told them my issue, Nathan from Groundhog showed up at 12pm and by 12:20pm, my AC was working and my family was happy and cool! Nathan was very knowledgeable and friendly, very professional. I haven’t needed any HVAC services in this area (SE Aurora) I’m so glad Groundhog came through for me today, great overall experience. Thank you Groundhog!

Pete C.

Nathan was very courteous and professional. he was great at explaining the issue and the resolution. thanks!

Melissa G.

Very friendly and knowledgeable. Came out on short notice to fix a problem two other companies couldn't figure out.

Jamaica S.

Truly stellar service. It wasn't an inexpensive service, but like heart surgery, do you want the service / certification of your furnace going out to the lowest bidder? I felt as though the service provided was definitely worth the price paid. Brooke was very knowledgeable and kept me informed with each step she was taking - pointing out things in the furnace to educate me. Groundhog will be the only company we use from now on!

Debbie A.

Absolutely did great work. On time, great communication. All around strong work

Have worked with Groundhog over many years and have watched Carrie and Pat build the business into a professional, reliable and reputable heating contractor. I use them exclusively on the properties I manage because of their prompt response to "no heat" or "no hot water" calls from my tenants. There great to work with.

Chris B.

I have been working with the team at Groundhog Heating & Air for several years now. I have referred them to countless clients and hired them for my own HVAC needs, and I get rave reviews every time.
THANK YOU for being professional, efficient, and honest. It's a tough combo to find these days.

Bailey D.

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.

Chuck R.

Plumber came with a smile and great attitude, then reinforcement crew came with new water heater, respectfully completed work and left—and, the area was spotless. Thank you!!

Linda S.

Our air conditioner stopped blowing cold air on the hottest day of the year. Nathan from Groundhog HVAC was able to come out that day and install a new capacitor while performing a thorough system check. He was great. Very informative and knowledgeable. Would use them again and recommend them highly!

Thanks for great help with the HVAC METAL AIR PIPE WORK!

Pat at Groundhog was very knowledgeable and informative to our problem and was easily able to suggest a solution. Arrived as scheduled and work was completed quickly and done very professionally.

I called Groundhog and they were who could actually get to me in a timely manner. Right away the person on the phone helped me get my AC system working again. A couple of days later a technician came by and inspected the system and found nothing wrong with the system other than it needed a good cleaning. My AC may have never had a regular service - we bought the place last year. We scheduled a tech to come out later and service the system. They were very flexible about getting here when I would be available. The tech had to reschedule the first service appointment. This happened to work out for me and I tend to be pretty flexible. Plus we (the tech and I) both knew my system was actually working. So this wasn't an issue for me. Groundhog will definitely want to give more warning to most people though as many people tend to be less tolerant. I did not get the impression that rescheduling on their part is normal. The main thing here is this - It was mid summer and hot. My AC was barely working when I first called them. The could have sold me just about anything and I would have paid for it to get my system working. But they did not. They only sold me what I needed. Trust is an important thing between a homeowner and people that we have service our homes. I'll definitely call these guys the next time I have an issue they can work on.

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.

Quick, professional install of a replacement furnace at a fair price. Gave guidance on picking between the two models I was considering.

Happy Homeowner

They are absolutely fantastic. They are very responsive, very professional, once the person came they treated my home with respect. They are very efficient and extremely nice!

Happy Homeowner

Nate was very professional and got things working in a jiffy, but still took his time to check everything out thoroughly. He fixed a blown fuse and I felt it was very reasonable. He was also really good with my overly excited dog, which was really nice.

Happy Homeowner

Patrick and Carrie are very kind, courteous and professional! The products, pricing and service are the best bar none

Happy Homeowner

Technician was extremely professional. Willing to take time to fully discuss issues and answer all the questions I had

Happy Homeowner

Wow! Groundhog far exceeded expectations from the moment I called through the finish of the job (4 hours after I placed the call!). Their great communication, responsiveness, transparency on pricing, friendliness, timeliness, and great workmanship will earn our repeat business and recommendations for friends/family looking for HVAC companies. SO glad I took a chance on them today when the other 3 HVAC companies we've used told me "no" or "maybe" to an emergency non-working furnace (a day before freezing temps as a high). The technician, unprompted, showed us how to do the fix ourselves if it happens again. They seem like genuinely great people who care about their customers. We paid $180 for the flame sensor replacement and $69 for the system evaluation.

Happy Homeowner

Awesome ! can't say enough ( positive ) about these people !! Wouldn't hesitate to use them again!

Happy Homeowner

I have recommended Pat to several of my real estate clients and they always email or text me what a great job he did and how his service was superb and his pricing very competitive and fair. I will continue to refer him to any of my clients who need any HVAC work!

Lee M.

Knowledgeable, friendly, prompt, and fairly priced. These guys are my go to for HVAC needs. Don't hesitate! Call them now!!!

Pat, Carrie, and everyone at Groundhog Heating were wonderful. Attentive, professional, honest, and willing to share knowledge with my plethora of questions. After another company started a fire in our furnace while repairing it, Groundhog answered their phone & sent someone out within an hour of speaking with me. I highly recommend these fine folks when you're in need of HVAC assistance.

Jodi M.

This company is amazing!! I was getting nervous with no heat and cold weather coming tomorrow. I called this morning and Pat was here in 3 hours to fix our furnace. Hallelujah, we now have heat!! Initial phone call was great, service was great, price was great!! I'm definitely a loyal customer now!

Sandi G.

Pat and Nate did an amazing job installing our new high-efficiency furnace and tankless water heater in our home. There was so much attention to detail - they carefully assessed the best plan for running newly required venting for the products, and they stayed late to complete the job on time and under budget. Pat addressed our failing dryer vent as well, and we are grateful. We have complete faith in the installations and appreciate the product options offered - with Groundhog Heating & AC's advised maintenance these will serve our family well!

Cathy B.

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 O.

Groundhog was awesome today. My condenser for my AC stopped working last night. I tried to fix a couple things myself but hit a point where I was stuck and out of ideas. I called Groundhog at 11am, by 12pm Nathan from Groundhog was at my house, and by 12:20pm my condenser was working and my family was comfortable again! Nathan was great, very knowledgeable and friendly, super professional. The charges were reasonable and fair (thankfully I only had a small issue so it was pretty cheap). I appreciate Groundhog getting my AC going before the heat hits this weekend. I hadn't needed any HVAC service since I moved to this house (SE Aurora) so I'm glad Groundhog came through for me today. Thanks Nathan and Groundhog!

Pete C.

We recently used Groundhog heating for the purchase/install of a whole house humidifier. I received multiple bids and while Groundhog was not the cheapest (which is good since I have never found the cheapest price the best long term option), they were the most responsive and willing to spend the time explaining the technology and options, without any sales pressure. The installer was on-time and very professional. Overall very positive experience and I will not hesitate to use them for my upcoming basement project.

Dan F.

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.

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.

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+++!!!

Michelle M.

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.

Michael K.

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

Blake H.

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

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!

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!

Who 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!

Patricia C.

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 Yay!

Marge W.

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 another party to help. I am keeping your number and will absolutely be in touch when something comes up

Andy L.

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.
