When it comes to all-around service, Hiller stands in a league of its own. From plumbing emergencies to electrical installations, they have consistently demonstrated a level of professionalism and efficiency that's truly commendable. I recall the Sunday when my basement was flooding due to a collapsed pipe. Hiller was quick to respond and even quicker to devise a plan, fully restoring our water supply in less time than they initially estimated. Their proactive communication was just the icing on the cake, making us feel at ease during an otherwise stressful situation. Moreover, the technicians, especially Allen and Daniel, have been fantastic. On one of the hottest days of the year, Allen was working tirelessly in our attic, not just doing his job but going the extra mile to clean up after. Daniel, meanwhile, was a true problem-solver when it came to identifying and repairing a leak. His patient explanations helped us understand what was being done, making us feel part of the process. I'm equally impressed by the email and call updates I've received throughout my experiences, courtesy of Steven, Scott, and Chris. It's rare to see a company so focused on keeping their customers in the loop. Not to forget technicians like Joshua Cook and Jordan Brown, who not only addressed our immediate concerns but also advised on preventive measures and future upgrades. Last but not least, the customer service from start to finish has been nothing short of amazing. The convenience of online scheduling and real-time updates (kudos to Nicole and Chanel for their professionalism) made each service call feel like a well-orchestrated performance. If you're in need of professional, timely, and courteous service, I can't recommend Hiller enough. With a team that's committed to exceeding expectations, they're the only ones I'll be calling for future home service needs. Thank you, Hiller, for being a company that genuinely cares about its customers. Looking forward to my next exceptional experience with you. Close

2nd time using Hiller after a great first experience. I had a dishwasher installed. The experience was excellent with Daniel. He was incredibly kind, knowledgeable, and prompt. We live in an older house, which makes projects more challenging than anticipated, and he knocked it out of the park like a pro! Highly recommended and will certainly use Hiller again in the future!

When my hot water heater went out, I wasn’t sure who to call for help. I’m so happy I called Hiller. Jordan Brown was the technician who installed my new one, and he was stellar! Arrived right on time, was super kind, answered all of our questions, and made us feel so much better about the situation. He installed our new tank within a few hours! He was really a pleasure to work with, and I’m thankful Hiller and Jordan were able to help at a moment’s notice. Close

Jason and Sophie were the technicians that resolved my electrical issue. They were professional, courteous and very knowledgeable.

On Sunday, 8.20.23, we had to call Hiller due to plumbing problems...basement flooding out every time water was being used. They came out and discovered The cast iron pipe collapsed under the stairs in front of the house & said they could come back Monday morning to fix it but we could be without water for 48hrs. They arrived Monday morning around 10am and was completely finished by 3:30pm & we were able to use water! They are always very nice and respectful and do a wonderful job! Close

Hiller was able to schedule an electrician quickly to come out to fix damage that was done by an installer that was out to supposedly install a dishwasher. The electrician came out, arrived early with my permission, did the work quickly and was very thorough in the work that he did and explained everything that he did so that I would understand it and could guide the person who would come out next to finish the installation. I recommend Hiller with no reservations, they were professional, worth the money, friendly, and thorough, and now I'm not worried about my house burning down while I'm sleeping. Close

Allen, our technician, was amazing! One of the hottest days of the year, he was crawling around in our attic, trying to install new LED lights in our exam room. He was courteous and made great suggestions for efficiency. Best of all, he cleaned up every scrap of dust and material, and took the old broken equipment with him For disposal. Good move Hiller on hiring Allen! Close

They were wonderful and I would highly recommend. Scheduling online was easy. They even called to let me know the technician was running a little behind and would arrive at the later end of the window given. I thought that was above and beyond given the fact he did arrive within the window. Jordan was nice, professional, and immediately identified my issue and had it fixed fast. Every step of my interaction with Hiller was excellent. Thank you for fixing my leaking toilet! Close

I have had hiller do several jobs for me over the past several months. The work, for the most part, has been good. The technicians have been professional. My only gripe was my most recent work done. My AC stopped working and was holding water in the basement. The first technician came out, said the condensate pipe was clogged, and flushed the system. I was charged a little over 200. This worked…for less than 12 hours. I called again and a different tech came back out. He stated that the pump was broken. This was replaced, and I was charged 650 dollars. I was a little annoyed that less than 12 hours before, I paid a substantial sum, for it to not be the permanent solution. When I questioned tech #2 about this, he stated that while he understood the frustration, it was non negotiable. Decent companies should say, hey we missed the real problem initially, let’s work with you on the second price, or refund the first. Don’t expect this from hiller. Overall, good work, kind staff, just unwilling to admit their mistakes. EDIT: 6/29/23 13:26 Hiller reached out quickly to resolve this issue with me. They have agreed to refund the initial visit that was unsuccessful. Honestly, I’m impressed. Will be changing my review to 5/5. Close

I have used Hiller for annual maintenance and little surprises that are a part of owning a home for many years. After getting several bids to replace two HVAC units we decided to go with Hiller. From working with Micah, the project lead, on the size of the units to the pricing, to the installation we were very pleased with the process. The team arrived shortly before 8, they were professional and took the time to go to each HVAC unit explaining exactly what needed to be done. Unfortunately we needed vent rerouting - which that interaction validated the installation team and project lead reviewed the install before they arrived. Every time I had a question Alex or Zach would explain in detail the component or what they were doing. Once they were finished they cleaned up the outside area, garage and attic. Start to finish 8am-4:00 … (for 2 units). Alex, Zach and the two other installers were excellent! Close

Our tankless hot water heater developed a leak from one of the lines and was dripping on the ground every time hot water was used in the house. I went to make an appointment and was able to find and opening the next morning. Very simple to schedule service using their website and was able to upload a video of our leak in action. The technician arrived on time and I was given a heads up with tracking information to know when to expect help. He was very courteous and quickly diagnosed our problem and offered a solution. He worked quickly and did not make any mess. He even offered to check out other problems around the house to avoid having an additional house call. Overall extremely pleased with the speed of service, quality of work, professionalism and we'll highly recommend them. Thanks Dylan and Hiller! Close

Excellent work! Not only did the technicians do a great job replacing a bunch of old cast iron and lead piping - including the main stack (old and new pictured) - they also walked me through their plans beforehand, complications and solutions throughout, and the all various components of the replacement/repair afterwards. This was a really big job, but the replacements/repairs were done efficiently and function perfectly. Well done! Close

The technician was able to come earlier than expected which was great because the problems were affecting my ability to work since I work from home. Once diagnosed he was able to explain what occurred to cause the problems in a way that made sense, and he explained the cost for any work needed prior to starting any repairs. I will definitely use Hiller in the future over others I have used in the past. Close

My toilet broke early Saturday morning. I immediately began calling plumbers but either no one answered or I was told it would be Tuesday. I called Hiller and was right away speaking with someone who was kind, polite, and determined to help me. She arranged for me to be a work-in on Sunday and gave me details of what to expect. Sunday morning early I received a call from Hiller with another nice lady telling me the tech was on his way. Daniel soon arrived and was so kind and nice. He quickly found the problem and soon corrected it. He was pleasant the entire time and had me at ease. He explained every question. I was very pleasantly surprised with this entire experience from initial call to completion of service. I have already recommended them to family and friends. Close

I have been a member of the Happy Hiller Club for several years. Recently my AC stopped blowing cold air and it got pretty toasty inside the house. I called the office and spoke to Aubry. She directed me to turn off my unit and then scheduled me for a technician visit the next morning at 8am. I was so relieved! No one wants AC issues in Nashville in the summer. Ben Kelley arrived right on time, diagnosed the problem and fixed me up. The house was cool in no time. These guys are life savers!! Close

The plumbers installed a new water heater and showed me what had happened to my old water heater (damage from electrical wiring burn out). They worked diligently and cleaned up after the instillation was complete. The electricians installed the wiring for the new water heater. I greatly appreciated the electricians and the work they completed. They explained every step to me and reviewed the work before they left and cleaned up. I had a lot of questions regarding options for future electrical work and they took the time to explain each option to me. I was very happy with the plumbers and electricians work. Their attitude was professional and warm. Close

We had a plumbing emergency on a Sunday and Hiller was the only plumbing service (out of 3 that we called) that responded immediately to our phone call. While we had to wait several hours for an available technician, when one became available we were kept very well informed on his estimated arrival. He (Garrett Hall) was extremely pleasant, courteous, and explained what he was doing to resolve our problem. He had us back in business in a short amount of time. We’ve never used Hiller before this, but they have our business now! Close

Amazingly prompt after-hours service provided by gracious, caring, professional and competent individuals. Zach came to service AC unit, and promptly diagnosed the problem as electrical. Scott came shortly after to repair and replace exterior electrical panel and my air conditioning was restored for the evening which was especially critical for the comfort and well being of elderly visiting mother. Everything about this organization and their employees is startling and refreshing to see. The two men who made quick work of my needed repairs in the midst of intense heat at night came in clean trucks and attire. I don't know how these gentlemen are able to maintain such clean and unwrinkled white Hiller shirts both upon arrival and after finishing the job. I wonder, do they change clothing after each job? Also, the systems Hiller uses with text messaging to let me know that technicians are on the way is amazing. I am truly happy. Thank you Hiller. Close

We had the heat go out when the outside temp was 20 degrees. They made a special trip to accommodate us the same day even though we were not a customer before this. We had a senior and a 2 year old so we really appreciate the service and know we can sleep well tonight. The service man was incredible and spent time to tell us exactly what the problem was and how it would be fixed.

Matthew was perfect! Not only did Hiller get some one to me the same day, but he arrived right at the beginning of the time frame they gave. He was compassionate and explained everything to me in layman’s terms. He consistently let me know about the charges before he did the repairs, and he even went the extra mile. I was wary of using Hiller since I hadn’t used them before, and I’d had a terrible experience with another large company. He made me feel comfortable as a female homeowner, and I never felt like he was trying to take advantage of my lack of plumbing knowledge as I’ve had happen In the past. The whole experience was pleasant and cost effective. I’ll definitely use them again. Thank y’all so much for restoring my faith in these types of service calls! Close

My experience with Hiller was incredibly seamless from start to finish. I called in the morning after discovering my water heater was leaking. They did not have an open appointment for a few days, but the agent called around and was able to work me in for a same-day replacement!
