They did both electrical work and plumbing and were thorough, professional, explained what needed to be done. Their promptness and prices were fair and I highly recommend them.

Replaced two outside water faucets. Kind of a delicate job but Luis pulled it off perfectly. Thank you so much for another job well done.

Jeff Olson is the MAN! He did such a wonderful job installing a 220V outlet for our dryer that we moved from our top floor to our garage. Clean, kind, professional, quick, great price and the whole job just looked so incredible! Had to run this along the wall with smaller pvc pipe and drill into our ceiling, but he did it so neat and perfect we were smiling ear to ear! Will be calling on GB for all future projects to come!

I cannot say enough great things about Green Box Mechanical. I called them for a service repair on my air conditioning unit. I had one other HVAC company come and take a look and told me that my unit needed to be replaced. The cost would be $5000 to replace the unit. The technician from Green Box looked at my system and determined their was a faulty part. The total cost for the service call and part was $350. Green Box was transparent and honest in repairing my AC. I would highly recommend them and use them again for my HVAC needs.

We hired Greenbox to run the electrical for our hot tub. We had also hired them in the past to run a 30amp for our trailer. The work was good. They removed the crawl space foundation vent to pull the wires, never closed it back up and now we have a $3,000 rat problem under the house. Poor execution on the details that is now costing us big dollars!

We have been looking for a plumber for a small residential job. Having contractors show up and show up timely is so rare. Luis was prompt, considerate, informative and knowledgeable. I highly recommend.

Jeff Olson was fast, efficient and easy to work with. He squeezed us into his schedule this morning to get our dishwasher hooked up, even though it took a bit longer than expected due to old wiring. He checked a few other things we were concerned about as well. Great service! Thank you so much!

My project was just not something that could be done because of my condo board, but the Greenbox team was REALLY great at trying to hash it out with me. Scott and Mike were really wonderful to deal with. I chose them in the first place because they came so highly recommended and I would call them without any hesitation if I needed anything else done. :)

They were able to come next day (which is important when you dont have electricity). Other places were two weeks out. Steve was knowledgeable, friendly, and on time. He was able to find and fix the problem quickly. I would definitely use them again.

We work frequently with Mike and his team and enjoy the variety of trades they offer which make it often a one stop shop for us. I have a lot of projects on my hands so having reliable and reasonably priced vendors is a main priority. Thank you for all that you do GB

Highly recommend! Their electricians and scheduling staff are top notch. Jeff and Sarah were great to work with.

Want to say THANK you Steve Harper, for your great work and help in getting my hot tub and GFI back up and working, plus the installation of my new porch lights. The HT was in bad shape but you went the extra mile in making sure I new what was what, and appreciate your taking the time to explain and provide your recommendations on how to fix the problems it was having. Outstanding customer service; you have a customer for life. Thanks, Steve...

Greenbox Electrical was amazing. During a power outage we had an emergency situation and they responded immediately so we could get power back. They were thorough and professional and I would highly recommend Mike and his team. THANK YOU GREENBOX!!!

I cannot thank Steve and Green Box Mechanical enough. Their amazing fast service and expertise could not be matched by anyone! Steve, the electrician they sent was very friendly and really knew his craft! He even spotted a few issues the home inspection missed on our new home!! We all feel safer knowing our system is in tip-tip shape!

We had new siding put on our house and needed some electrical work to go along with it. After several bids we chose Green Box for their reasonable pricing, good communication, and timeliness. We are very happy with the work they did. Unlike some electrical companies, they charge by the job, not the hour, but we never felt like they were rushing to complete the work on our house and get to the next job. When they needed to come back to fix something minor the city inspector wanted done, they scheduled a follow up with us and came and took care of it. If we need any electrical work done in the future I would definitely use them again.

JC Kootnekoff, owner of Green Box Mechanical Posting his own glowing review for Green Box. I would like to tell the world that I am so very proud of our committed service technicians and front office team. Thank you all for your hard work and dedication.JC Kootnekoff

We paid Green Box $200.00 for a permit to install dryer vent. Inspector came out to inspect vent. He said NO PERMIT was required for this instalation. They charged us $200.00 for a permit that was NOT required. This company is charging $200.00...which goes directly into thier pocket. If you are having work done through this company before you pay them...check to make sure a permit is required...we are now out $200.00. The hole that was put into our new bamboo floor for the vent was not put in properly and was done without consideration to placement. Will not be using this company for any future projects.

Highly recommend Green Box! Weve used them twice now, the first when we first bought our house to update our electrical to grounding outlets and again when our AC broke and we decided to removed the ducts and install ductless. Not only did the team, on both occasions, provide reasonable quotes, but they were very professional, on time, and explained everything to us in detail. While installing the ductless, one of the team members accidentally stepped on our plants in the garden. They could have just moved on and not say anything, but he made a point to apologize to us which was unexpected. Weve had other contractors come out recently to give quotes or do work and everyone of them stepped in our garden yet not one apologized. The Green Box team were kind, helpful, didnt talk down to me as a woman, and they kept to their budget (both time and money). Well be using them again for any future needs.

All the work weve had done with them has been wonderful. Mike shows up when he says he is and gets the job done and the prices are good. I would highly recommend them to anyone who needs electrical work done.

Okay, so let me start by saying if you need a fix for something easy and are not in a hurry - these guys are great - in the past I used them with no issued for very small jobs. However, if you need anything at all complex or are on a timeline DO NOT USE THEM. They held up my house closing, I had to call back a bajillion times to get guys out 2 or 3 times for things that should have been done day 1 despite being very clear on my timeline from the beginning. Everyone there tried to pass the buck to someone else. The plumber said he could not do the job I needed and told my buyers it could be a $15,000 fix (wow thanks for that). Had another plumber come - said it was easy and would be about $600.

Prices are high for doing simple things even changing out a light switch. Be sure to get a quote before they do the work and do not feel bad about getting them at your location and telling them NO.

I URGE you to not use this company for your electrical or plumbing needs. Our contractor brought this company in to do the work on our bathroom and kitchen and we are SO disappointed in their work and professional behavior.1. The electrical work in our bathroom was pretty minor. Move 1 electrical outlet, place 2 sconces and make our outlet a 220V vs. 120V for our new gas range. Firstly, when he came to do the work he said some pretty misogynistic & concerning personal things. Not only did he make ME super uncomfortable, but his fellow plumber and my contractor were thoroughly disgusted by his commentary. Worse than his demeanor, the job he did was wrong...twice. First, he hooked up the sconces incorrectly so that you had to turn on 2 light switches at a time to get them to turn on. Second, he changed the 220V outlet to what LOOKED like a 120V outlet, but when we put the electronic meter in it, it was still running 220v. It could have COMPLETELY destroyed our new stove. Thankfully, they did send someone else out to fix it who confirmed his work was wrong and re-did the work quickly and efficiently. Our contractor continually told them about his erratic behavior and poor craftsmanship and Greenbox just defended him saying there had been no other complaints.2. Our plumber was very nice, but did subpar work. When he noticed our pipes were old galvanized pipes, he recommended additional work to go further back than originally intended in our shower. We appreciated his advice and the charge was extra to re-do our shower drain line which we were fine with. However, we noticed he went only halfway back - not all the way to the connection. (Our new plumber said this was just lazy work - he also used the wrong turn in the shower drain which our new plumber said we were lucky to pass inspection with) He also took the sink line and made 2 new connections for our vanity as we now had 2 faucets. However, after all the tile work was done and my contractor went to hook it up, one of the hot water faucets didnt work. When he came back to fix it, he told us it was our fault for not getting that section of galvanized pipes fixed. He never suggested that when he was working on the sink, and said hed need to either rip out all the tile, or enter from the other side to fix it. I was so TIRED of Greenbox at this point, that I told him to just tie the hot water off of one line so I could be done with them. Before he left, he suggested we re-pipe the whole house and that it would cost anywhere from 15-20k. When I called in a different plumber (Pipeline plumbing who was a PLEASURE to work with) - they re-piped the entire house for us for a fraction of that price and even FIXED all of the work that was done in the bathroom incorrectly in the first place.Its one thing to be unhappy with the work, but the extremely unprofessional behavior with the electrician was abhorrent. What makes it worse, is they continually tried to send him out to us (we demanded a different electrician for that 220 mistake) and took no actions to speak with him about his actions.Do yourself a favor and choose someone else for your plumbing and electrical needs.

We had water leakage issue for a few weeks but could not identify the root cause. Finally we decided to seek help from professionals. Justin was easy to work with and very experienced with the situation. He provided a few proposals and soon the issue has been identified. The price is competitive as well. We are happy with the service and will definitely go back to Green Box again.

Great electronic communication from start to finish. Onsite customer service was excellent, timely, and professional. Jeff knows what he is talking about and respectfully explains the solutions in laymans terms.

These guys are awesome.We have used them a number times and every time they do a great job.Prompt, professional, and most importantly, they know how to fix things.Probably one of the top two contractors I have ever worked with and head and shoulders above some of the big outfits in town.

It seems like somebody decided to reinvent the whole concept of on-call plumbers and electricians. If so, the result is GreenBox. And they nailed it. The whole operation is professional from the person who answers the phone to the guy who shows up to do the job. The guys who do the work are friendly, organized, prompt, efficient and very good at what they do. AND they are reasonably priced. Ive used them twice. Both times their estimate -- and final bill -- beat the competition. Maybe best of all they act like the really care.

Green Box Mechanical installed a new heating/AC system in our home. They did extensive research on our home, designed the appropriate system to suit it, and finished a difficult job on time and on budget. Throughout the process they were extremely knowledgeable, responsive, timely and clean. They are real pros... definitely a top-quality vendor who I would hire again in a second.

Great customer service and always a job well done!

Jeff helped us with an electrical project, working to provide a quote that was the cheapest among several. He had to come out a few times for follow up corrections, based on inspector demands and was always gracious, with Greenbox scheduling him quickly. We also had a gas quote from Greenbox and at the time the plumber noted some active leaking from our water heater and fixed it on the spot for a reasonable fee. Good folks all around.

Fantastic Experience. Mario T. came in, diagnosed our electrical issue, found a solution that saved us time and money and was respectful and pleasant all the way through! Thank you and I will be calling you guys again!

Michael was awesome, came out quickly and educated me on how to optimize our furnace for maximum cooling efficiency on these recent hot days. His advice made a huge difference. Didnt charge me for the visit and didnt try to sell me anything. What more could you ask for??

Eric and the Green Box Mechanical team were excellent to work with. They were able to attend to an electrical issue in our home at very short notice and went out of their way to help fix another problem we had. Their bid came through very quickly, they were super professional and very friendly. Green Box Mechanical come highly recommended.

Super awesome and helpful people. Chris helped me save money. Thank you!

I had water leaking out of the ac/furnace and Greenbox was able to be at my house a hour after I called. They did a great job fixing unit.

Green Box Mechanical just completed the replacement of our old 80% gas furnace and air conditioner with a new 97% gas furnace and heat pump. Now that we have experienced some hot days, there is no comparison with the old system. The new system just purrs like a kitten & keeps the set temperature. With the old, it would be 4 to 6 degrees warmer than what was set.They were very professional and courteous and left us with a very tidy installation. Cost wise, I thought they treated us very fairly and were competitive with the other 2 bids I had for a lesser systems. The new system is fantastic and very quiet. As an architect, I can be hard to please, but they did it! I would highly recommend them. They also helped us get a $500 rebate from EnergyTrust.

When we moved into our new house, there was a lot of work to be done that we could tackle ourselves just fine. When it came down to the electrical bits, however, we knew to get the professionals.We had a variety of things that needed fixing, upgrading, or installing, and several that were optional. Green Box Mechanical was super quick on not only responding to our inquiries, but also getting someone out to give an in-person estimate. Professional and well within reasonable costs, they scheduled the work for soon after, had it done, and now we couldn’t be happier with the result.We left some of the optional pieces out during this upgrade, but we definitely know who we’ll be calling when we need another electrical job taken care of.Highly recommended!

I can’t say enough good things about how professional and responsive GreenBox has been for both our plumbing and furnace needs. Our faucet broke last night and by this afternoon GB installed a new one! Thanks to the entire team for amazing customer service.

Mike at Green Box Mechanical got right back to me after I requested a quote. I didnt have an emergency but need a bathroom repair soon. Mike got me on the schedule at a convenient time for me. Devin knew what the problem was right away and had it fixed in 20 minutes. Ill be calling them again next time I need a repair.

JC, Mike and the Greenbox team have done a couple projects for me over the past couple of months. They are quick to respond, provide a competitive quote, and most important, get the job done right. If you are looking for a company to service your electrical, plumbing, or HVAC needs, give them a call.

Based on my limited interactions, I would highly recommend this company.

I would highly recommend green box mechanical for electric. plumbing, hvac, and any job around the home or office. VERY professional.

The food was good, but bit spendy for casual dinner.

We had to do a complete re-pipe of our one level ranch home with a crawl space basement. Galvanized pipes were replaced throughout. Devin came and gave us a great estimate and we scheduled within a couple of weeks. The communication throughout the process was fantastic. We even asked for a couple small additions to the job which Devin said no problem and did them at no extra charge.The estimate was the final price! We learned Devin is a 4th generation plumber and he is very knowledgeable. The convenient thing about Green Box is they are one stop shop with the ability to handle all aspects of the job because they have electricians too so there is no sub contracting or hassle to get someone to come and do what the plumber cant during the job. Would highly recommend and will use them again

Top notch people who do a great job- on time, responsible, up front about pricing. Would definitely use again!

I needed some minor electrical work to sell my house and Eric did the work promptly, professionally, pleasantly and for a fair price. As good as it gets!

Devin just finished a commercial restaurant plumbing install for our company. He was succinct, timely, professional, and communicated well with us. Excellent job!Peter HermannKOGI Ventures, LLC

Greg was so helpful. Installed wiring for lamp quickly and creatively. Reasonable pricing.

Had them repair an HVAC unit repaired after it went out during the last heat wave. Service was prompt and professional, had the unit up and running very fast. Will definitely use them in the future.

If youre asking about the quality of the work done, I have no problem with Greenbox; their work passed inspection, they were pleasant, arrived when they said they would come. But they ignored my requests and didnt do the work I requested.I asked for four tasks to be done, the most important to install an outlet strip in my art studio. I also asked them to repair broken light fixtures in the bathroom, and to give me estimates for two other potential jobs: Installing new recessed ceiling lights in the studio, and then to check the outlets in a new backyard shed, ensure that I either had a 20-amp circuit in at least one outlet, or there were two 15-amp outlets on separate circuits, and if not, give me an estimate for installing same. I left a copy of the instructions with my roommate as well (since I couldnt be there on the day they were coming).When I got home that night, I found a bill for $870, and only one of the four jobs done correctly: The bathroom lights had been repaired. There was no outlet strip--I was told theyd forgotten to bring one (why, when I told them what I needed?), but would come back and do that for another $190. They did include an estimate for putting in ceiling lights, but instead of my requested recessed lights, one over each work area, they quoted $726 to simply replace the existing ceiling fixture with a fluorescent version (and have it inspected).If Id wanted that, I would simply keep the fixture that was already there. The studio area is actually two rooms, separated by a door; installing a ceiling fixture in one of the rooms wouldnt help the poor lighting in the other, in any case.The real problem, though, was that theyd added a new circuit to the shed without my approval instead of checking to see if it was necessary and calling me with a quote. I have, despite repeated requests, never been told whether it was actually needed (and suspect it wasnt).I had no choice but to pay the bill. I told them I was very unhappy about that, got the equivalent of a shrug and a next time you should be there, which is undoubtedly true. Mostly, though, Id REALLY needed that outlet strip, so I told them I wanted that installed asap, and I did NOT want the ceiling light done. When could they come out? Monday, they said. They also told me that the county inspector would be coming out that week to review the work done in the shed.Monday came and went, and when I sent a note asking if they had an ETA on installing the outlet, I was told they were waiting for me to pick which ceiling light fixture I wanted. I repeated that I wasnt doing that, I just wanted them to install the outlet strip as promised. They responded that they were waiting on me to decide on the light fixture. Huh?Then I asked when the inspector would come, and was told theyd cancelled the appointment because they were waiting on me to order the ceiling fixture. I appreciate that they wanted to save me the price of two inspections, but Id already told them that the only additional work planned was the outlet strip they were supposed to have installed that day and didnt. I asked again when theyd be out to install the outlet strip, and again was told they were still waiting on me to decide on the light fixture!At that point, I pretty much gave up. I sent the check for $870, and told them to send the inspector any day, just let me know when. Several days later Greenbox emailed that they still needed payment. I assumed that theyd lost the check, so I went onto their website and paid the bill, then canceled the check from my bank (at a $25 fee).Update: Mike Llewelyn of Greenbox contacted me to explain that they did NOT lose my check, instead they never received it, and asked me to correct that part of the review. Im certainly willing to give them the benefit of the doubt on that. The check has never been returned.The inspection was finally held a week or so later--the outlets in the shed passed with flying colors. So...good work, but marginal customer experience.

Scheduled everything, then rescheduled everything, then cancelled leaving me to in the lurch. Terrible experience- we’d be in a better place had we never heard of these people.

Got a quote, then they showed up the same day to do the work! Very impressed with timing, work, and best of all - competitive price!

The folks at Green Box Mechanical have helped us in all aspects of their business -- plumbing, electrical and HVAC -- and did so promptly, efficiently, courteously and professionally. They worked around our schedules, figured out how to repair past contractors mistakes and did so without breaking the bank. We have worked with many contractors over the years remodeling 13+ houses, and we can recommend GBM without hesitation.Thank you to Mike, Greg, Brian, Devin and Matt for putting our home back together.Lynn Estuesta

Wow. JC and his team have completely nailed it with a very service-oriented one stop shop. I work in energy and electricity and am slowly switching over many of my home devices and appliances to be grid-smart and to cap off and decrease my homes use of natural gas due to carbon, air quality and safety issues. Most of the very capable contractors I called didnt really get it when I explained my move toward smart, connected appliances that can make better use of the solar on my roof. Mike at GreenBox got it and called around to learn what he could to make my project work.I have a 110 year old home so I have worked with countless home contractors over the years but these guys are working hard to think about the future, whole home service models and then when they have a hiccup or two in implementing that vision JC just totally stands by their work and puts in the time to figure it out. I was really happy with the gas to electric water heater conversion they did for me. Everyone was friendly, considerate and worked with me when I expressed any concerns about price, implementation or other questions.I plan on doing a major renovation next summer and will definitely be using Greenbox.

Excellent service, price , and expertise.

Great guys!
