Have been with Grasten for many years. Our service technician Landon Golden was awesome. He was extremely professional and knowledgeable. He took his time to service our generator and cleaned it up so it looked new when he was done with the service. I appreciated how friendly and courteous he was. And of course- always appreciate that he showed up on time as scheduled. Grasten is a dependable company and we plan to keep them for future services and repairs if needed.

Stetson did a great job assessing the problem with our generator and repairing it in a timely manner. Appreciated his knowledge and honesty in explaining what needed to be done. I thought maybe we needed to replace the generator?? He assured us that the repairs had taken care of the problem and we should be good with the current equipment. Everyone who answers the phone is kind and knowledgeable. Great company to do business with!

We love Grasten so much. Josh Keller and everyone one else there are top notch people. Our service man today, Dennis Brown, is just another example of what a reliable, professional outstanding, above the rest company they are. We intend to never leave them.

We love Grasten. You are not a number to them. I looked at five different Generac dealers before choosing Grasten, which, I found to be the most professional, nearby where we live, a preferred dealer for Costco members, other neighborhood people used them, etc.Travis, a technician of theres, was fantastic for our commissioning and maintenance. This is the second time weve worked with him.Look forward to working with Grasten in the coming years.

Just got a service contract with Grasten. He just left. What a difference. He checked everything. This is the only company that actually serviced my generator. I had three other companies that were horrible. Ark really ripped me off. So glad I finally have a honest company that actually services it. I highly recommend Grasten.

I acquired by generator several years ago and Grasten installed it and has serviced my equipment in a very professional manner since I purchased my 22kw.All of the people I had the pleasure to interact with have been very professional and a pleasure to work with.As to my interaction with Travisthe tech who serviced my unit this time. He was extremely polite and provided complete responses to all of my inquiries. Travis was very polite and exhibited that he knew what he was doing. If I had to rate his performance I would say he did very well.

It was a long wait for install to begin but that was made clear to us from the start. Once the process kicked off, Jackie communicated wonderfully with me to coordinate the installation dates, explaining in great detail each step. Each of the trades were friendly, professional, and obviously skilled. The tech that did the final commissioning with me did an excellent job explaining how the system worked and spent as much time with me as I wanted. I highly recommend Grasten Power Technologies

This year we decided to go with Grasten Generators for our yearly maintenance because they only do generators. Chris was our maintenance serviceman, he arrived on time, went above and beyond explaining exactly what he was gonna do, how he was going to do it and offered suggestions and tips for the future. You could tell Chris really enjoyed his job… he was proud to work for Grasten. He was extremely focused, efficient, diligent, extremely friendly and courteous, and kept us updated throughout the maintenance appointment. Graston is fortunate to have such a valued, likable and professional employee in Chris.

Micheal and his crew were awesome. Very respectful and courteous. He was very willing to answer any questions I had and took the time to explain the setup and the process. Thank for an excellent job well done.

I was mostly pleased with the generator purchase from Grasten. The price was good and very competitive, the installation crews seemed very qualified and did a wonderful job and I am giving them 5 stars because of this, but there were some short comings. My installation was scheduled to begin 7 to 9 weeks from my contract date of 7/5/2024. My generator was dropped on 10/14/2024 and final start up was 11/8/2024 so one can see the installation was very late. They indicated that they were extremely busy with new sales and installations and the recent hurricane which I understand fully but their lack of communications regarding dates of the 3 phases of the process was definitely lacking. Even though it was late, I gave them 5 stars again because of the pricing and quality of the installation itself.

Makay was very thorough and detailed during the start up process! He showed my husband how to do maintenance on the generator including what oil to buy to keep on hand and lots of tips on what to do between yearly service calls. Highly recommend!

David Martin, Grasten Service Technician,performed the service of my 48KW General Generator in a very professional manner. I would be very happy to have David provide his services any time.I recommend Grasten Power Technologies to everyone that questions what company I use for Generator Purchases and Services.Best regards,Gary LaBlue

Davin did an excellent job on our annual service. Before working on our unit, he told me what he was going to do and after completing the service, he told me what he had done. He founda good amount of oil at the bottom of the unit and cleaned up the oil and wiped the unit down inside and out. He found that the cause of the leak to be a faulty the oil pressure switch and replaced oil pressure switch under warranty.

Landon Golden was a wonderful Generator Maintenance guy.He was so polite, explained everything he was going to do. He offered to have me watch what he was doing as he explained every step of the maintenance procedure. I was very pleased with his service. I would welcome him back again to service our generator.He rates 10 out of 10 in my books!!!Thank you Landon Golden for a job well done.Pat Conrey

Tech came out for yearly maintenance. Found issue with it starting. Troubleshooting the problem found issue with gas vent. Generator is back on line with service ticket written to fix issue. Hope to hear from Grasten to set date to take care of issue. Dayton did a good job working on generator and explaining the problem. Would recommend Grasten for your generator provider.

The service technician today did a great job. He was professional and pointed out that the oil was low and offered to said he could walk me or a neighbor through the steps needed to add add it in the future. My only regret is that Graston is not closer to me so that I can request a service call. Thank you.

We have utilized the professional services of Grasten since 2020. They are reliable and knowledgeable. The owner, Josh Keller, has built a team of solid professionals, including Steve L, who just completed a routine service appointment this week, which was coordinated by the always helpful and friendly Dylan.

I was extremely pleased with the service provided by our Grasten technician on our Generac generator. He called ahead and when he arrived, he introduced himself. He was always very polite and professional. He walked me through the process and explained everything very well. I was extremely pleased with the service we received.

Sean was outstanding and I can’t commend him enough. Knowledgeable, respectful, courteous and extremely helpful when servicing my generator. Spent time with me talking through all he did and provided additional information to ensure I fully understood how to care for my investment. If I could put in a by-name request for Sean for all future service, I most definitely would.Grasten - take good care of Sean because he’s taking good care of you by taking care of your customers. I can assure you, you don’t want to lose him.Thanks again, Sean!

Travis did an outstanding inspection on our generator. I had many questions after our generator ran so many hours during Beryl . Travis was patient and answered every question. Showed me how to check oil, and add more. I feel comfortable now if there is another time that our generator keeps us up and running for days. Thank you Travis. Toni Johnson

Review 24 (2024-08-21 - Rating: 5)
Arrived on time and promptly began the service call. He explained things to me as he moved through the routine: checked the transfer switch and emptied/filled the oil, changed oil filter and put in two new spark plugs. He did a very nice job of cleaning the inside and outside of the generator. Great job, pleasant person!

Review 25 (2024-09-27 - Rating: 5)
Excellent service from Grasten, again. Dennis did a great job of explaining everything to me. Working with Grasten is easy - from installation 4 years ago and through out all maintenance and any questions - I cannot say enough about how easy it has been. The generator has worked flawlessly.

Review 26 (2024-08-03 - Rating: 5)
Sean was very informative, very knowledgeable, was great to work with. I never once felt he was in a hurry to leave. He made sure before he left that he answered all my questions. I sent him a text message letting him know that our AC stopped cooling right after he left as the capacitor went out. He called about 25-30 minutes later and put my mind at ease.Sean was AMAZING!!!!

Review 27 (2024-09-22 - Rating: 5)
Tested and ready for use, serviceman worked quickly and had the unit ready in a short time. He helped me get registered in install the app on my phone and insured I was ready to receive information from the generator.My only complaint was that it took more than a week after installation for someone to come out to complete the start up.

Carlos was very thorough, and found the problem right away. he also checked All of the output specs and cleaned up after he was finished. He was friendly and asked if we had any other concerns. We received very good service . We recommend him and Grasten for any of your Generac needs or service.. Thanks!

Giovanni was FANTASTIC! Went over everything very thoroughly with me. Showed me all the switches, powered up the Generator, explained everything in detail and answered all of my questions. He is wonderful - very personable and professional.

Review 31 (2024-08-04 - Rating: 4)
Grasten Power Tech was almost on my bad list. Bart came out and inspected our needs for a generator and came in with a fair bid. I was happy with how he reflected Grasten and we accepted his offer. We were told it wouldn’t take more than 5 weeks but we sat for 8 weeks. Communication from administration wasn’t the best after the contract was signed. While we know they have had a surge in customers - that communication in following up with us wasn’t giving me the warm and fuzzies. We finally received the generator at week 7 but the install was not for another week and the actual walk through and power up would be on another date that was never given. Needless to say this was frustrating. The electrician finally came out Friday and something wasn’t right so they called out Colt who I found out is a new operation manager for Grasten to check their work. He didn’t want us to wait - came out on a Sunday/ TODAY on his own time and fixed the issue that Fridays crew had. After we explained our frustration - He got us up and running Today!! Thank you Colt sincerely for getting this done! Your great instruction on keeping our Generac up and running should make a difference and avoid common issues when this starts up for the first time! I would give you a 5 star.

Review 32 (2024-08-21 - Rating: 4)
Upon start-up of my generator, Sean showed his professionalism in speaking to the customer and explaining the details of the generator operations. The test run ran smoothly except for a glitch with my built in oven which he quickly took care of the situation. As stated, more persons like Sean should be a part of your company to provide great services. As for your initial dealing with scheduling or even identifying the installation date of my generator was a very difficult experience (I was aware of Beryl). I ended up contacting Generac headquarters for someone to respond to my inquiries. I kept calling and continued to leave messages, but to no avail, it was a lose-lose experience. I finally received a call from someone, and started to receive messages on my phone which was convenient for not receiving a call back. I finally received my installation date and start up date, and everything is satisfactory. Give a special thanks to Sean, Victor and Ignacio!

UPDATED Review:Dillon and Val were able to get my issue with my recently installed Kohler generator fixed.The issues I was running to were:1) the meter needed to be adjusted to provide more fuel for the generator to get its initial turn over to start, which is why it was taking 3 to 4 times to start.2)the Kohler app shows under the controller tab the amount of time the controller has had power / been connected to batter. Its not the run time of the engine which is hidden in a different menu.When actually dealing with the installation crew or service managers such as Dylan and Val Ive had a pretty good experience.My only real issue, and its a big one for me, is their communication with their customers at this point in time SUCKS. I get that it is probably because they are growing rapidly because of the fall out from the Derecho and Hurricane Beryl, but they need to find a better way to manage communication between themselves and their customers.

Review 38 (2024-09-23 - Rating: 5)
Just had my annual inspection and Dennis did a great job. Walked me through everything he did and any observations he made. It was good to get back up to speed on how the generator works in case I ever have to go DIY during an outage and work on it myself. Great job Dennis!

Colton did an excellent job of representing Grasten Power Technologies in our quest to obtain a backup natural gas generator for our primary residence. All of our questions were answered expertly and understandably. He has been outstanding in making sure our expectations are grounded in reality. His knowledge of Generac is extensive. His passion for providing best in class customer satisfaction shines through. We are confident that the execution phase of our project will proceed as planned due to the professionalism demonstrated by Colton throughout our interactions.

Im 100% pleased with Grasten support, technicians, and company as a whole. Theyve always been very helpful, upfront, and honest. I hear my neighbors complain all the time about the companies they used to install and maintain their generators but Ive never had an issue. I recommended them to everyone who ask me about my generac.

We had our Generac generator serviced today and Chris Jones did an excellent job.

Grasten technologies recently installed my Generac generator purchased through Costco. Unfortunately hurricane Beryl rolled through our area before the installation could be completed, knocking out our utility power for several days. Grasten (thank you Jackie and Emily!) was kind to send a plumber on the day after the storm to complete the installation. The awesome Grasten owner (Josh Keller) called me late that night and walked me through the startup procedure step-by-step, restoring power to our home 36 hours after the storm rolled through. Grasten has been very professional and responsive throughout the installation process, and were kind to help me get my unit started during what was a difficult time for their staff as well. Thank you Grasten!!! Very pleased to have worked with Grasten on the generator installation.update: Stetson (from Grasten) came by today to do the commissioning. He arrived promptly and walked me through the procedure for operating and maintaining the unit. Very patient and courteous. My experience working with Grasten staff has been nothing short of stellar!David Martin performed the annual maintenance on the unit and sent the report. Very professional company to work with!!

Thank you to all. Clay and Sharon Wyer.

Very disappointed in Generac, unit failed with major part (rotor) needing replaced after 24 service hours. Grasten sent technician out after a week of trying to reach them during storm. He immediately knew the problem and did the disassembly on the unit. The parts were ordered and installed in 3 weeks. Same service tech who did a great job installing and testing

Review 51 (2024-10-11 - Rating: 5)
Easily the smoothest Home Improvement Project Ive ever been involved with! From start to finish, every part of the process happened EXACTLY as it had been scheduled. No four hour windows of when someone was going to show up. Two hour window and every trade arrived at the beginning of the window! I was impressed. Sam Tanner was my start up tech and he did a super job of explaining every detail of what he was doing and checked with me to be sure I understood. I intend to ask that he does my regular maintenance service. From the sale (most competitive and knowledgeable presentation) installation and startup I was never stressed; that says a hell of a lot for any HIP! If you are in the market for a standby home generator Grasten might not be your pick but youd be making a mistake by not having them evaluate your projectUpdate 10/10/24: Gotta give props to Sam Hanner and Grasten again. Sam is the MAN, came out and handled a minor warranty issue but insisted on doing a system check, cleaned the unit inside and out. The guy just goes above and beyond. Sam is an asset to Grasten and a customer advocate. Unless I was totally shut down Id wait for service until Sam was available. I dont leave this type of review unless its deserved; it is!

These guys are bar none the fairest and best folks in the generator industry to work with! Josh and his crew are always there in an emergency answering his phone and ensuring people are taken care of. All of his technicians are professional and courteous. His prices out beat anyone on top notch generators and installation. It’s all about service after the sale and Josh and Grasten Power is the best in the Houston area!(Update 2023) Years later and I can still say in all confidence that there is no better company out there than Grasten when it comes to Generator installation, maintenance and repair. Don’t waste your time or money elsewhere!(Update Hurricane Beryl) 4 days no power but my generator worked the whole time! When maintenanced properly (stopping the generator and adding oil every 36-48 hours and a full oil change after 100 hours of running) Generac and Grasten came through for me! As someone who lives with a chronic illness and is extremely sensitive to the heat, I can say things would have been very different without my whole home generator. Thank you once again Josh and crew!

Sean Murphy was an exemplary technician that was professional, thorough and courteous. He was able to come out and hook up our new generator and ran all the necessary tests and was able to explain all the maintenance processes to us in full details. He also answered all the questions that we had and I have the utmost confidence in his skills and professional advice. We would definitely recommend Sean Murphy because he is a an excellent technician and Generac representative ensure that your Generac generator will run properly for years to come.

It took 4-5 weeks longer to get the generator than we originally were told, however, Beryl caused most of that problem. Colton, the salesman pushed it across the finish line for me. The hook up with Ignacio’s team out of Huntsville went great and Dennis did a super job of completing the set up.

Giovani and Anthony (Electricians) and Robert (Plumber) overall did a great job, polite, professional easy installation. I would give 5 stars but there are 3 small hiccups.1) they cut/drilled a 4 hole for 2 woth of wires and filled the 2 with silicon, and its unsightly. The Plumber also drilled a whole in the fence plank that wasnt used as he had to drill the one used 6 higher.2) a regulator was not provided nor was I directed to purchase one, to reconnect my gas outdoor fire pit to the new gas line. Even though it was discussed as part of the service.3) no key was left or came with the generator mechanic.All three of these issues have been brought to the attention of the office, and are awaiting disposition. I would still recommend Grasten Power.

Grasten did a great job of repairing our generator when it failed after Hurricane Beryl. The technician (Dylan), was professional and easily diagnosed our issue. I know Grasten has been swamped with customer requests as all generator companies have been overwhelmed at this time. I know Grasten is responding as quickly as they can. Their technicians are working 18 hours a day and doing a remarkable job.

Our generator ran for 179 hours after Hurricane Beryl. We had power while the Heights did without.Perhaps more telling, a few weeks later a technician is here at 8:47 PM on a Friday night changing the oil and spark plugs for me.Even after starting the day around eight in Missouri City, this guy is capable, friendly, and focused. (He took the time to clean up some oil from a a previous oil change.)This level of service and diligence is exceptional and what we have come to expect from Graston—even as they are running all over the Houston area to service and maintain generators.Thank you.

First time interacting with Grasten or its face for the company, a tech named Dennis. After purchasing a home with a Grasten installed Generac, Dennis thoroughly explained operation and maintenance of the generator -- gives me total comfort that it will work as intended when needed. Professional, thorough, knowledgable and practical --Dennis was great!

I bought a generator through Grasten. The guy who sold me the generator no longer works there and unfortunately soldMe the wrong size generator but thanks to Chris, he has helped me get the absolute most out of my generator and trouble shoot the areas that were not set up properly at the beginning. He is patient and talked me through the process and made everything super user friendly. I could not recommend him enough! It’s because of Chris that my generator now works proficiently for our needs!

**Grasten Power Technologies: Exemplary Service and Support**During Hurricane Beryl, our Generac generator failed due to a known manufacturer issue that led to excessive wear on the brushes. While this was a frustrating experience, Grasten Power Technologies, our generator installer, truly shone in their commitment to customer service.From the outset, Grasten demonstrated exceptional dedication to resolving our issue. They diagnosed the problem and took every possible step to get our generator back up and running. Despite the setback being beyond their control, they were relentless in their efforts to assist us. They even managed to get our generator temporarily operational, though not until after power was restored.Grasten’s team worked diligently to ensure that Generac was made aware of the faulty part and facilitated the process of getting the rotor replaced. Their proactive approach and communication throughout the ordeal were commendable.While I cannot recommend Generac generators based on my experience, I wholeheartedly endorse Grasten Power Technologies. Their professionalism, expertise, and unwavering support during a challenging time proved their commitment to customer satisfaction. Grasten truly stands behind their work, making them a trusted choice for generator installation and service.

It is with extreme gratitude that I share this review of Grasten Power Technologies. I’ll start by saying we’ve been customers of Grasten since 2021 and they have ALWAYS done a terrific job.On this particular situation, our power went out due to Hurricane Beryl. Immediately our Generator kicked in and was working great. On day 3 we Decided we’d better check the oil level since it was running non stop. Once we went to restart, it would not restart and after consulting with Generac hotline to troubleshoot we discovered the keypad that is needed to startup has gone bad and we needed that component. On a normal day this would not have been a problem to find but during a major natural disaster it was next to impossible. Luckily Josh at Grasten called us back at 7pm that same day and was able to secure the part for us. My husband was able to pick it up and Josh walked him through set up and install over the phone. Our generator is now back in working order.We are so pleased and grateful for Grasten and their level of service to their clients and our community. They are professional and working tirelessly during this difficult time to get us all back and running!

David Martin performed maintenance on my Generator today. The generator performed well during Beryl for my neighbors using my home as a cooling station. I was out of town. David replaced the oil & battery. Generator ran well during test. I had bought warranty 8 months ago. No charges for excellent service today!! I discovered Grasten Technologies when I bought my generator in 2021. The generator stopped working & they performed warranty work, replacing the generator. I had not been pleased with original installers. I have been so happy with all the professionals I have encountered at Grasten.

Man what a week - I am so thankful I got my generator from Grasten Power Technologies. With the power going out Monday early - my home never missed a beat. My air worked and we operated like normal. We had family over that were without power and the generator worked like a charm. Even with phones down - internet down - cell phones not working. I felt confident in the Grasten Generac system installed to keep my family comfortable. If you are looking for a back up. Look no further!

I would have preferred to learn more why our generator stopped when we needed it most, but Sean has carefully checked out all the circuits, alarms, switches, whatever there is, and was confident that there was nothing wrong with the generator. He simulated a loss of power to the house and the gen picked up the load without complications. So were hoping that next time Entergy leaves us in the dark, that our gen will come on as designed.

Review 102 (2024-06-22 - Rating: 4)
We signed the contract on May 10th and the generator was operational on June 21st. Considering the City of Houston permitting hassle this is excellent timing. Everyone with Grasten Power Technologies was easy to get along with and seemed truly interested in getting the job done right. The only issue I had was getting information on job status. On a couple of occasions it took the better part of a day to get updates on schedule.

Review 112 (2024-05-29 - Rating: 5)
After a storm came through on May 28 my electricity went out but my generator didnt start up. After the storm passed I checked the generator and the light was half yellow and half red. The panel had an alarm saying low oil pressure so I checked the oil level and it was really low. I added some oil and cleared the alarm then it started right up. Then I noticed that it was spraying oil from the oil pressure sensor so I shut it down. I called Grasten, who installed it, and told them about my problem. They said it was going to be a few weeks before they could fix it because of all the recent storms and repairs they had to do. It was still under warranty but my problem was that I have a disabled son and that I would have to stay at a hotel until power was restored. This was at 2:30 and Grasten had a technician at my house at 6:30. But this review is really about the technician Sean. This guy did an awesome job. He was very professional, friendly, and explained everything before, during, and after. He had me up and running in no time and also did a complete check of my system. Sean gets 5 stars from me and should be recognized by his superiors for not only doing a great job but being an outstanding employee.

Re: Sean MurphySean came to do our annual checkup on our Generac generator. I was very upset with Grasten when he arrived because we NEVER got any response back from them after several phone calls and texts. These messages occurred during and after Beryl Hurricane was over. Sean was the first contact we had and that was for a previously scheduled appt.Sean apologized for our bad experience but explained how busy Grasten had been. He was very professional and patient. He answered ALL of our questions. He was knowledgeable on every issue. Before he arrived we were considering going with another company for our generator needs, but after talking with Sean we decided to give them another chance.Sean Murphy is a wonderful asset to Grasten.

I purchased my 26 kw Generac from Grasten Power Technologies and have to say that the purchase and installation went great.We were fortunate to have it during and after Hurricane Beryl and it provided enough power to keep us comfortable for the next 7 days until our community finally got power again.Just know that you need to let it rest about 30 minutes to an hour each day. After the first 30-45 minutes be sure to check the oil level as you will need to add some oil every couple of days. Be sure to use SAE 5W30 Full Synthetic oil which you can find at Lowe’s, Home Depot and Walmart, etc.SAE 5W30 FULL SYNTHETIC.

The electrical cabling was VERY professional and plumbing for natural gas is nice and tidy. Startup technician went over all aspects of maintenance, operational information and emergency FAQ.

Your technician Makay Higgins found the problem with the battery not charging when the generator was running. He discovered that the connection on the panel was wrongly done when the generator was installed in September of last year. Kudos for Makay and his expertise in finding the problem and fixing it.During the Beryls power outage, I utilized 3 new batteries, two of them are ruined and do not hold the charge, the faulty wiring damaged the batteries. I got reimbursed for one of the batteries and I am going to ask Grasten to reimburse me for the other one, there was no issue with the battery but with the generator panel wiring.Thanks
