Best HVAC people ever! They fix it right the first time; charge a fair price and do it with a smile! If they would have installed our furnace 8 years ago we never would have had the problems we did. We went through 3 other companies before we found them. Just call them! You will be glad you did! read more

I bought a furnace from Zach at Go Green in mid October 2012. My initial dealings with him were great. He seemed honest and helpful. The furnace was installed on time and for a reasonable price. They, however, did a slipshod job of creating a place for the air filter. The incoming air just goes around the air filter instead of through it. Unfiltered air going into my new furnace motor will drastically shorten the motors life. Zach said he would get it fixed. A month later, after several guarantees to repair the problem, the situation has not been rectified. Warning... Be careful about having this guy in your home. He offers a free inspection of total heating space to ensure you are buying the right size furnace. But, while he is there, he is looking at your art and making judgments about you and your family. Then, he goes back to his office and researches you as an individual via the Internet. In my case, he found an adult industry tie. All absolutely unnecessary to install a furnace. Before he sent his installers to my house, he briefed them on the art in my home and what he found on the Internet. Then, while in MY home, installing a furnace, his installers had lengthy conversations with my minor daughter about what they been briefed on by Zach. They questioned her about the art in the house and various other embarrassing and unnecessary topics. I highly recommended you avoid Zack and Go Green Heating and Air Conditioning. I have filed a complaint with the BBB since he refuses to repair the problem he agreed was a problem. He needs to keep his Christian values out his customers homes and discussing things with customers children is a major etiquette violation of reasonable and ethical business practices. Zack has replied saying my daughter must have overheard the installers talking outside. It was 8 degrees outside that morning and she never left the house. The younger of the two installers was simply sitting around, in the house, chatting with her. The installers NEVER should have discussed anything with her whatsoever. Much less, adult topics and the warnings they had received. He refers to the photos in my house as "pornography". Boudoir nudes are NOT pornography. He says he briefed the installers on the the content of my art so they could decide if they wanted to exposed to such things. The installers would never had any reason to be in my upstairs master bedroom. They came in the front door and went right to the basement. They would never had known they were even there if Zack had not felt it necessary to make a big deal out of it. His own installers said my house was not at all what they had been briefed to expect. You can see from Zach's reply that he does, indeed, personally judge his clients. You can see what he had to say in response. His job was to measure my house for proper heat loading. Not to judge me then have my daughter briefed on his opinion. Just one mans opinion. Update... It is now February 2013 and my heater is still running without a filter system. read more

So far I have only used Go Green for a furnace tune-up, but when I called, the lady on the phone was super pleasant and accommodating. Zach showed up on time and they even called to let me know he was on his way to my house. I wanted to learn how to change my furnace filter, so i crawled down into my crawl space with him and Zach was SO patient and explained everything he was doing. Gave me reasonable quotes/estimate on what it will cost when I am ready to install a new furnace and water heater in the next year or 2. Overall, super happy with the service I received and that I felt like he was giving me a down to earth, honest opinion on my current system, not trying to sell me anything I didn't need at this time. Thanks guys! read more

I bought a house built in 1929 owned by my grandparents since 1960. I received many estimates. When Go Green Heating and Air came in to give the estimate. Zac the owner asked many questions the others did not. How many windows where the windows would be (it was a complete remodel) He did many measurements of the house. He answered all questions professionally and made suggestions that saved us money in construction. On the day of installation the crew was on time and very professional. They did an amazing job on the furnace and the AC unit. The inspector from the City even made comment of what a great job they had done. We had many changes in duct work and all were addressed in a timely manner. This company was the most reasonable in price and impressive from the beginning and to the end of the job. My furnace works great and the airflow is very even throughout the home. I have been working with several contractors and being a woman found it refreshing that Go Green answered my questions and my husbands with great explanation. I highly recommend their service and have complete confidence you will be another satisfied customer! read more

Zach came out to troubleshoot my HVAC. He was honest, came right at the scheduled time, and provided good service. I would definitely use him again for any Trane type HVAC systems. read more

Great service. Great people. We just had an AC unit installed and John did a great job. Everyone was so great as new mom with a big dog in the house I was worried about having someone in the house all day but by the end of installation I couldn't have been more comfortable and confident about this company. We had our heater repaired l last winter by them and gave it another go since we were happy with them then. Really exude a company that does things right and strives to do the right thing even if it is inconvenient for them. Appreciate them so much and love the AC. read more

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. read more

Zach was incredibly knowledgeable and friendly. He got my heat back up and working in no time.

I purchased a 4 ton Trane A/C condenser unit with the coil and pad from someone on Craigslist for $550. I had no idea how central air systems work and I thought I got a great deal. I looked online for someone to do a free estimate for the installation and Zach was the first to get back to me. When he came out to my home he was very friendly and professional. He explained to me that he wanted to go through the house to look at the furnace and take measurements first and then look at the system I purchased. I'm not a "shoes off in the house" kind of person but he made sure to put booties over his shoes prior to entering my home to avoid tracking in dirt. He walked through the house measuring the different rooms and marking down how many windows were in each, he explained in detail why the number of windows as well as the number of air returns were important in calculating the correct size unit for my home. He explained that he would do a Manual J load test to determine the correct size unit for my home but that he also felt just by looking at it, that my 4 ton unit was probably too large for my space. He advised that he could install it if I wanted to but he explained the problems that occur when having a unit too large for the space. Lastly, we went out to the garage to look at the unit and coil. He explained to me that Trane is a very reputable company with quality products but he also explained that the 3.5 ton coil I had was too small for a 4 ton A/C condenser unit and he explained that the unit would end up being overworked which would shorten the life of the unit as well as cause the coil to freeze up (which the guy I bought the system from did say had happened to him). I asked him for an estimate to install the system I purchased as well as what it would cost to install a completely new system. Within a couple of days he emailed me a quote as well as the results of the Manual J Load test that he had done. He explained thoroughly what it would cost to install the used unit I had and what it would cost to purchase a coil that was designed for the size condenser I had as well as advising of the risks and problems I would be facing such as the shortened life of the unit because of being in a space smaller than it was designed for. I decided the cost for installing the used system was not worth it compared to the quote for installing a brand new Carrier system designed to fit my home. I had received a couple of quotes last year (although nobody offered to do a Load test, much less to do it for free) so I knew what he quoted was very fair.The only thing I had received from previous estimates from other companies was a threat that if I waited, it would only get more expensive. On the day of installation he and another gentleman showed up on time and Zach explained to me what they would be doing as far as routing the lines and and he offered to answer any questions I had. A couple of times I went to look at what they were doing and to see how everything was going. Each time Zach asked if I had any questions as well as explaining where they were with the installation and what was left to be done. It took them about 4 hours to complete the installation. They were both very respectful of my home (and my wife) and I am extremely happy with my new system as well as with the education and services rendered by Zach at Go Green. As I said before, I received estimates from other companies last year and not only was Zach's estimate lower than theirs but they didn't even mention a Manual J load calculation, much less offer to do one for free. I can honestly say if it wasn't for Zach at Go Green Heating & Air Conditioning I would not have been able to get a brand new AC system installed. I would have ended up having some hack on Craigslist install the used system I have and I would have ended up having problems as soon as it gets hotter and I really needed it. Thank you Zach! I appreciate it and God bless! read more

Called Zach this morning with a furnace problem where it lit and then died but the blower kept going. Zach was extremely patient and walked me through a couple of possible problems on the phone before we found the culprit which was a partially blocked vent. He offered to come out if need be but he was correct that we could fix it over the phone! Thanks Zach, fixed furnace with no service call or cost. I'll certainly call Zach next time I end up with a furnace or AC problem! read more

This company should be your first choice when looking for a cooling/heating unit vendor! I usually don't go through the trouble of writing reviews but Go Green did such an amazing job I had to spare 5 minutes to right this review. We needed a new air conditioner/furnace unit for our home in July. My husband made a handful of cold calls and meet with 3 different vendors. Based on the initial meeting with Zach my husband thought Go Green was the best choice of the 3 vendors. I am so happy he decided to have this company replace our units. Zach and his staff are quick and responsive. We were able to get the installation set up the following week and completed within a 7 hours. We were both home by chance during the day of the install and the technicians spoke with both of us and provided us with recommendations on maintenance to keep our new unit running properly. Also, the ducts in our older unit was not sealed properly so they were able to help us seal off the ducts. I'm so glad they were nice enough to give us their professional opinion because we assumed the prior owners had everything set up correctly. Since I moved to Colorado I have heard multiple coworkers and friends share their horror stories about repair/home improvement vendors. We did not have this stress or worry with Go Green. read more

I left a message for Go Green to have my furnace replaced. I will admit that I called during a severe cold-snap in November 2014 and I'm sure they were dealing with a few emergencies. Anyway they did not call back until one month later. I already had my furnace replaced by 1st Call (also reviewed in Yelp) by then. read more

Zach came out to our home and did a free manual J test and estimate for our new a/c system. He was very professional and timely. He gave us a very reasonable quote, and it was the best price for the high quality Carrier system he installed. We decided to hire him. On the day of installation, he arrived on time with another gentleman. Both men made sure to introduce themselves to me, as they had only spoken with my husband prior. They were very respectful of my home and didn't mind my small dog checking up on their work. The A/C system was installed and the electrical work was completed within a few hours. They were very respectful of my home and cleaned up great - had I not been home, I would never have known they were there. They charged us exactly what was quoted. NO hidden fees or surprise charges at the end. Zach from Go Green is very professional and I will recommend his company to friends & family. Thank you Zach and God bless! read more

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 didn't need. I would hire Go Green again. read more
