DO NOT WASTE YOUR MONEY WITH THESE IDIOTS!!!!!!I am SO regretful I ever called this stupid fraud of a company to come to my house and touch my HVAC system. 3 years later and they have caused me nothing but headaches.   In 2022 during a heat wave our upstairs AC system went out.  Desperate for anyone to come to our house, Green Horizons, was able to come and inspect our system very quickly, which was originally very appreciated.  (stupid stupid stupid)We ended up deciding to replace the entire upstairs HVAC system with a new one through Green Horizons.  The install went terribly. On the day of the original install, it all seemed to be ok until they left.  Within 2 hours we noticed that the AC was NOT working, air was coming out of the vents but it was not even remotely cold, it was clearly just the fan pushing air out, not AC. This was a brand new unit (allegedly) so it was clear that this was an issue with the install itself.  We called them to come and figure out what they had messed up, they came back and did god knows what, saying they fixed the issue. They left, a couple of hours passed and.... it once again stopped working.This series of events went on for literally an entire month.  We had to call them to come and fix their mistakes no less than a dozen times. Not to mention that during all of this there was some sort of leak in our attic that left a stain on our ceiling where the HVAC unit was.  They said they would send someone to paint over the water stain, but this never happened, and by the end of this ordeal I did not care and did not want their incompetent people in my house to mess anything else up.The stain on the ceiling is still there, taunting me, reminding me of how much I hate these people. The overall issues seemed to be resolved until recently.  During the recent heat wave we once again noticed that our AC unit was not pushing out cold air *deep annoyed sigh*.  At this point we have found a new HVAC technician who we actually trust and has done fantastic work - we had him/his team come out to look at the unit, and wouldn't you know it..... there was a soldering issue during install that has been allowing freon to leak out of what should be a closed system, so we are having to have that fixed and having to pay for new freon. I cannot say enough how much this company is the bane of my existence. They actually suck and I would not recommend them to my worst enemy. DO NOT COME HERE read more

My experience with Green Horizon/One Hour Heating & Air continues to be very positive. In December, 2020 they replaced our furnace and we had no problems through the winter season. Last night I turned on the AC for the first time this year and suddenly had hot air blowing through the vents and my thermostat was not working properly. I turned the fan OFF and called Green Horizons around 7:30 pm. The lady I spoke with said she would get a technician out to me the next day. And the next morning at 8am, a technician, Bryan, was at the house. As it turned out the cause of the issue was simple -- a disconnected wire. Fixing that enabled the thermostat and the AC to now be working properly. The technician was courteous ,efficient and knowledgeable. I appreciate that Green Horizon addressed this issue so quickly and took care of this customer. Laura F. read more

I had One Hour Green Horizon replace an indoor evaporator coil under warranty three years ago. They were courteous and professional and everything worked fine initially. The coil failed again just three years after replacement and is no longer under warranty. The replacement coil is $2,300. A coil should last longer than 3 years. read more

I used green horizon/onehour heating & air to install a geothermal system at my house. They originally told me the geothermal field would run under my driveway, but then changed the plan and dug up my whole back yard without informing me or checking the property lines first. Their office staff kept telling me the project was completed and demanding final payment when it wasn't complete, there was equipment and debris all over the house, and I hadn't had a walk through. Early on, the system failed and leaked water all over the floor. The one good tech from onehour (Jason, I think) who I worked with finally figured out they had never installed a filter, which is pretty hard to install, through the bottom of the water furnace, and which I would not have figured out myself. The filter was also a special size that I had to order, so I know I was never given that information. The outside unit had also been installed incorrectly and he fixed that too. The thermostat was installed on a wall that I previously told them I was having removed. When they moved it to the correct wall, they cracked the wall and just left it cracked. They installed exposed ductwork and told me the diameter would be about 10 inches at the widest point, but it's 14, which is a big difference, and prevents me from being able to open the windows next to the ducts, which I didn't realize until it got warm out. Green Horizon never had the system inspected, claiming it was not their responsibility. Meanwhile other contractors told me it is the service provider's responsibility to have the work inspected, though one of the techs who came out told me it was a good thing it hadn't been inspected because it wasn't installed properly. Green Horizon then sent me a "final notice" in the mail (no phone call or other communication) stating that I had failed to respond to their multiple attempts to contact me to schedule the inspection, even though they never contacted me about it and refused to set it up themselves. I wasn't living in the house at the time the work was done so they could easily have set up the inspection themselves without needing to coordinate with me. I rarely write bad reviews but I would hate for someone else to have to go through all the trouble I have with this company. read more

See all

We just received an advert from Green Horizon- One Hour and a phone call from their office ready to sign people up for their Spring maintenance that we have had in the past. Maybe you have also? We have used Green Horizon for 10 years and have had a reasonable relationship with them until recently when they Franchised with One Hour   We will not continue to work with them as things changed for the worse. A month ago a problem developed with our Flow Centre and we were told it was still on warranty, except that we needed to pay for the new installation. The price was from a table of prices for each job. The guys arrived and did the work that was planned for.  When they had finished the Flow Centre installation and began flushing the system dark brown water appeared.  They had no explanation except that we must have a leak in the loop. They presented us with their bill and said they would return in a day or 2  when they had an explanation for our problem and would then finish the job. So we paid them (incidentally more than $100 over the "fixed" quote). That was a stupid thing to do on our part.  We have not seen them since. After they left we saw the green nicks on our new washing machine. They also banged the wall when they brought the Flusher equipment in the house. We called their office daily. No response. Eight days later we got an email from the person in charge Frank who we had worked with at various times. He said that we had a leak in the Loop and gave us the phone number of a Company that digs holes for loops. We did find the reason for the problem after consulting with another company.  They solved it in 3 hours because they knew what they were doing and had the experience.  Also their equipment was in better shape and cleaner. We didn't see the same ugly brown water in their machine as with the Green Horizon machine. We wrote Green Horizon and told them it was not a leak and we have solved our problem. We asked them to return our money as we had to pay another company to do their work. No response. They had not even given us a receipt at this time for what we paid them. read more

We had a compressor that was under a material warranty replaced in our AC Unit (original AC unit installed by same office group in 2010). We did not approve/sign an invoice before the work started. The work took 2-hour labor and needed 5 lbs of R-410A. The invoice we received was for $1100. It took two months (July 9-Sept 24) for One HOur to tell us they use "Straight Forward Pricing" (block pricing) and the compressor was considered a Level 5 difficulty. After talking to three local respected contractors, the fair and reasonable price for the work should have been between $650 -$800. Please be aware of any Company using Straight Forward Pricing and their membership with Success Group International. read more

Last week I had Green Horizons based in Durham NC, do energy efficiency work at my home. The work included sealing all my duct-work in the attic as well as sealing all penetrations between the living space below and blowing in additional insulation in order to bring me up to today's standards. (The home was built in 1974) In addition I had them replace all the duct work in my crawlspace and seal it as well as when they came for their initial inspection they found that my duct-work was riddled with holes and was completely uninsulated as well as being unsealed. Pictures were taken while the inspector was in the crawlspace so that I could see for myself the condition of the existing duct work. I initially contacted Green Horizons after receiving notification from Duke Energy that they were offering assorted rebates for home owners as an inducement to increase the energy efficiency of their homes and the first step was to contact one of their preapproved contractors. From their list I selected Green Horizons after reviewing the various contractors websites. I was extremely pleased by the work done, a total of two crews worked on our home and they were both prompt, courteous, and explained what they would be doing in detail when they first arrived. They also did a good job cleaning up after themselves when leaving. I noticed an immediate difference in my home after the work was completed. The HVAC system were not running nearly as much and temperature within the house was considerably more consistent. It's too early for me to tell exactly how much I will save on my monthly utility bills but I'm anticipating that it will be somewhere between 15-20%. If my expectations are met the pay off will take roughly 5 years at current utility rates and while this may seem long to some, equally important is that fact that my wife and I are much more comfortable. Green Horizon promptly handled all the paperwork required by Duke Energy in order for me to receive my rebates making this part of the process extremely easy. I heartily recommend them and as a full time Realtor will be recommending them to my clients as well. read more

Terrific, careful customer service and a great quality product for a great value. We felt cared for the whole way and learned a lot about our home heating system. read more

I am the biggest fan EVER!!! These guys are first class. From one thousand miles away i literally had a melt down over a AC issue in a rental property I own and they calmed me down and were so good about working with me on the issue, for two solid days 100 degree weather the guys were on point to help in all ways possible. I would recommend this team to anyone at any of their locations. They are the BEST. So dedicated. Sherie Silla read more

Had a wonderful install of our new HVAC system 2 years ago when we moved in. I have now changed my review to reflect how they currently treat their customers. Our heat went out Sunday evening during the snow, I call first thing Monday morning. Understandably, no technicians were available due to snow but I was reassured I would get a call back in the afternoon. That never happened, so I call back first thing this morning. I am told a technician will be at my home between 1-3. No one showed, I call the company back and she tells me my appointment is for tomorrow, and that I was confused. Tomorrow would have never even been an option to schedule as neither my husband or myself could be home. My husband stayed home today from work because Heat in the middle of winter is certainly a priority. Bobby, why did you let your company turn into this? Will never use them again and I recommend everyone else find service elsewhere. How does a heating company not understand the importance of heat in the middle of winter? For a kicker, my neighbor had a Spectrum Cable technician at her house but no one can come service our heating unit? read more

Hired Green Horizon to do duct work and insulation in our attic with the understanding we would receive a $250 rebate. Got the work done, but Duke Energy then said we did not qualify unbeknownst to Green Horizon. Green Horizon would later offer us an HVAC service plan for the trouble as well as followed up with Duke Energy and we received the rebate we were originally told we would get for the work. Their work was good, but more importantly, we greatly appreciate their following up with Duke Energy to satisfy a customer. read more

Green Horizon was great to work with from beginning to end. Their energy audit was very helpful, they were able to suggest what was best for our home and finances. The workers were on-time, respectful of our home, and did great work. read more

I must say that Chase Building Company that was/is owned by Walker Harris, who now co-owns Green Horizon, did an absolutely terrible job on the HVAC in our home (tubing not hooked up to the vents, holes in tubing, resultant condensation in crawlspace, etc) and also an abysmal job on the plumbing in our home with more than a few water pipe leaks related to incompetent installation and tens of thousands of dollars of damage. We have had a decade of endless problems related to the poorly overseen workmanship. And because of that, I would never feel comfortable using Green Horizons, co-owned by Mr Harris, for any services related to HVAC, crawlspaces, or plumbing! egad! read more
