Likely the best experience I have had with a HVAC firm!! I would highly recommend them. Professional, experienced and straight shooters, no nonsense. Eric O.

So far, two effective and reasonably-priced services at my house by Go Green. They also came out a third time to replace a defect part. Since they had installed the part, the third fix was completely free. Great service, with integrity.

Theyve had to come out to service my ac twice and have been absolutely great both times. Highly recommended

Great price on both a new AC and furnace, deep discounts for doing both at the same time. Installation went well!

My furnace was glitching and Zach came over and explained everything he was doing to fix it. A very pleasant and knowledgeable guy, I will definitely hire Go Green the next time I need HVAC service.

They were super knowledgeable and helped me troubleshoot my heating system, ultimately saving me a lot of time and money. Its hard to find honest and fair companies these days, my experience was really refreshing and I will use them again

Zach was great. Very detail oriented and upstanding individual. Will definitely call back for any HVAC maintenance in the future.

Zach creatively figured out how to get a conventional A/C system in our attic. He was very thorough and looked at all options and configurations. He designed and sized it right, for a good price. His installers did a great job. Were very happy after a couple months of use.

They have always done good work for me and are priced fair.

Zach came in and gave an honest and clear assessment of what was going on with our ac unit. He then laid out the options on how to fix it, and the implications of both options including price. We were so grateful he was willing to clean up the mess another contractor left!

My new furnace installed by Go Green has an issue which Go Green has attentively diagnosed and is repaiing. They were highly recommended to me and I feel their integrity is in the right place! Good people! Thx Lynn

Just finished the install for central AC. The entire experience was fantastic! Zach was very accommodating to my schedule to get to our house quickly to do the estimate. And the install went extremely smoothly! Everyone was very professional and kind to our dogs. Not to mention a great price!!! Very very satisfied!!

They have been our go to heating and air guys for years. Fair and honest pricing and did great work. They wont let you down!

Great service from Zach and crew! Zach appeared within an hour of my call about our broken furnace and had it fixed within minutes while he explained what he was doing and why. Cost was reasonable and honest. I highly recommend Go Green if youre in or around Arvada. Thanks, Zach!

We had a furnace and humidifier installed and are extremely happy with the work, the price and Zachs attention to detail. Zach came out before and after the work was done and was very informative on all aspects of the installation. He even did some fine tuning after the work was done and worked with us on a couple issues that came up during the installation in a very fair and reasonable manner. Very professional and trustworthy. I highly recommend Go Green.

We thought we needed a new water heater and called Go Green. I was really impressed as Mr. Whiteley presented our options, in all price points, based on the reality of our household needs. I felt he was very knowledgeable and honest. He was able to suggest easy, free maintenance we could do to save energy. He was prompt and clean in the instillation. He did not try to up-sell things we didnt need. I would hire Go Green again.

I have a rental house in Morrison and live in Indiana. They worked great around scheduling with me and my tenants. Installed brand new unit cheaper than i could get someone to do it on the side and has a great warranty. I would reccomend to anyone!! I also find it hard to get good service anywhere anymore. These guys get it!!

Zach is incredibly friendly, quick at his work and fixed my heater in seconds. Honestly the fastest diagnosis I have experienced. I am thankful to have a working heater in this freeze.

Recently installed central air conditioning our home. Zach came out to do the estimate. This is one of the few companies doing Manual-J calculations, which are really necessary to make sure you get a system that is the appropriate size. John did the installation and was super awesome.

My furnace was not working and Go Green came out within two hours of my call. After looking at the furnace for a few minutes the technician found that a part only had to be cleaned and he did not charge me anything other than the service call fee. My furnace has worked great ever since. They even called me a few days later to make sure it still worked. I would highly recommend Go Green Heating to anyone looking for a honest heating company!

I have helped flip houses and have been renovating mine for a long time. Ive been around the block when it comes to contractors, and this company is one of the best Ive worked with. Zach gave me a fair price and he knocked it out very quickly. Not having heat in February is a bit uncomfortable. I am going to use these guys again for my future projects.

I would highly recommend Zach and his company, Go Green heating and air conditioning to anyone who needs a competent, personable, prompt contractor for a price that is more than fair. Zach came out the same day I called him and performed the work in a quick and efficient manor. He did what we requested and didnt push to sell other services or try to say that there was more going on than what we had explained or had asked for.If you hire Zach, you wont be disappointed, we will be clients for life!!

Great service and fast response time. Professional staff that was very knowledgeable and easy to work with. Would definitely use again and recommend to all my friends!

Great company. On time, very professional, and the pricing was fair. Zach the technician was awesome and knowledgeable while he was doing my furnace tune up. He explained what he was doing and why he was doing it and what to be aware of later on down the road with my furnace. I would recommend this company to anyone.

They got out to my house within a day of my call, quickly diagnosed the problem, and fixed it on their first visit with a reasonable price.

I had an excellent experience with Go Green when my furnace died at the end of December. They quickly installed a new furnace and made the rebate process very easy for me.

Great experience working with Zach and his team. Just got a new high efficiency HVAC system installed by them. They beat everybody elses price and the installation was an easy process. Zach was very patient in troubleshooting minor issues that I had and followed up on everything. Their scheduler (Annie) was very accommodating. Im very happy to have found somebody local to be my go-to for my HVAC needs.

Ive been a customer of Zachs for years. He came out to the house to troubleshoot a problem. As always, on time, fast, efficient, and resolves my issues effectively. Would recommend him to anyone and will continue to be a loyal customer.

Very knowledgeable and efficient! So so happy to have our heating working again!

Very fast, super professional, helpful, and knowledgeable. After being run around by some other companies that we had made an appointment with and then THEY cancelled on US, Zach was available same day and even took time after his regular hours to make sure the problem was fixed. I am going back to them for any future HVAC needs without a doubt.

Go Green came to my home because my AC unit was not working. Zach found a burned out wire and then checked the compressor. Zach determined I needed a new compressor and quoted me $1800 or I could get a new unit for $2600. I called another company who came out the following day and they replace the wire and the AC unit worked perfectly. Zach never replaced the wire and passed the problem off as something else. Go Green and Zach should not be be trusted and any consumer should seek a second opinion.

I used Go Green to get my furnace tuned up for the coming winter. They helped take care of a small issue before it became a big problem which would have cost a lot more! I would highly recommend Go Green!

Air conditioning went out and they were here the next day. Ended up replacing the 30+ year unit with a more efficient unit as well as replaced the furnace. They came and worked thru the weekend and hauled away the bulky old unit. Great job, well done. Thanks

We lost our heat at 8pm at night. We tried many different companies, go green was the only company that would help us. They made it to our place in 30 min snd had our heat up and running in 15 min. The cost was so affordable as compared to other companies tbat wanted over 100 dollars an hour. The service guy was so great, i feel very lucky we found these guys and will definitely call them again!!!

After calling at least a half dozen heating service providers, Go Green was actually able to come take a look at our problem. Not only did the technician fix the problem, he came back the next week to replace a problematic part. The service was friendly, honest and affordable.

As a Real Estate Broker I am always looking for different contractors that do good work at a reasonable price to recommend to my clients. I not only recommend Go Green but have used Mark Strok to service and install HVAC equipment at my own personal properties. Go Green has never let me or a client of mine down.

Nice, timely and do not screw you on prices.

I was referred to Go Green by a friend of mine, since they had recently done some work for his family.On the day of the appointment, the office kept me updated via text, so that I was able to conduct my normal business around town instead of having to wait for the technician. It’s a nice touch, that I wish other businesses would emulate; especially since in this case the repair was at a (then) vacant rental property, where I would have been bored out of my mind if I had to have waited there.The last update I received was when Zach was leaving the prior job and getting ready to meet me at my place.Zach showed up on time, and diagnosed and fixed the problem with the furnace within 10 minutes. The job ended up costing me a lot less than I would have expected.I hesitate to recommend Zach and Go Green, because if enough people find out how great they are to work with, they might get so much business that they would be unavailable to work on my furnace the next time I need their services. But that wouldn’t be fair to them, so…If you need your heating or air conditioning equipment serviced, Zach and Go Green should be the first people you call.

Great service. Informed me of all options and costs before proceeding. For an issue where I thought my A/C was undersized, the tech informed me that it is properly sized based on a number of factors. Couldnt be happier.

I always rely on Zach. He is honest and does quality work at a great price!

Experienced and professional, Zac came to service my A/C and showed me how to maintain it to keep it running. Definitely my guys for heating and A/C needs.

Very prompt and professional service. I will definitely use them again.

Excellent service from a courteous and knowledgeable technician, highly recommended

Horrible company! Horrible!
