I have been a customer of Hiller for a few years now. They always provide great service and are always professional. I found a major leak in my water heater a few days ago. Jennifer K provided phenomenal service and was informative. The project turned out to be rather time consuming but she was very thorough throughout the process to ensure I had the best outcome. I was extremely impressed by her. If I had any plumbing needs in the future, I will be requesting her. 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

I called Hiller this evening and they were very responsive. The lady that I spoke with was very informative and respectful. She set me up with an electrician right away. Brian came out and got the issue taken care of very quickly. He explained and showed my wife and I the issue with our electrical and even explained the issues very thoroughly. I will definitely be using Hiller for all my electrical issues in the future. Thanks again Brian! You were awesome! Close

James arrived promptly at 5 PM, diagnosed our issue right away, and had a new hot water heater installed the very same night. I was really impressed with the quality of work and his customer service. I highly recommend Hiller if you need work done quick and well. 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

Totally professional from beginning to end. Website is great, scheduling was easy and it let me upload a video of the problem so the techs were prepared when they got here. Two techs showed up which was impressive. They kept us updated, got the job done, and cleaned up the whole area where they worked. Price was very reasonable. First class job. 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

I'm overjoyed at the services provided by Hiller! They tend to be pricey but very competent. I had an excellent experience with them installing a standby generator right before the last snow storm. The team arrived on time, was totally professional, and did an outstanding job. I am a Happy Hiller Club member and utilize the full spectrum of services there. 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

I was very happy with the service. Hiller was able to come out the same day I called them. I had leaking under the sink. The faucet and most likely the plumbing to the sink had not been replace in 56 years. Everything was taken care of in 2 hours at a very reasonable price. Second time I have used their services and have been very pleased both times. Close

The Hiller team is absolutely outstanding! I unfortunately had to replace both by HVAC units and I truly felt like their only customer. Responsive, friendly, knowledgeable, and they helped me every step of the way. I had the best experience possible from the tech to the project manager to the install team they were all amazing. Customer Service at it's best. I would highly recommend. Close

This company is amazing! I highly recommend Hiller! I have used them several times and They always go above and beyond to fix any issue I might have. Including extra repairs and taking time to run to a store to buy more parts. I recently received help from their repairman babes Garret. He was great and went out of his way! They are also very kind and that makes the experience even greater! Close

Matthew S. Is the absolute best. He was so kind and courteous and professional. He also took extra time to install a faucet that wasn’t originally in the work order information. He was so generous with his time. I am so glad Hiller sent him to my house today. I would recommend him to everyone. I hope Hiller will give him a bonus because his service was impeccable! Thanks Matthew!! Close

Aug 19, 2021 Micah Soto did a good job. Courteous and efficient. Scheduling was a problem with this visit as Hiller rescheduled once, then the tech was 45 min late. Hope this does not happen in the future. April 2021 Tech was on time and courteous. Tune up completed with no issues. Needed electrical work done. Work done right and suggested a couple of other things which were done at a reasonable price 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. Excellent Customer service and I would recommend this company to anyone needing service. Close

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

Very pleased! Replaced three toilets. John and his helper were great. Everything turned out better than I expected. A year ago my old, broken, hot water heater was replaced. Thomas, the technician, was knowledgeable, polite and a good listener. All jobs look terrific. I am very happy to have Hiller work at my home and would be pleased to have them back again. Highly recommended. Thanks! 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! Everyone was pleasant to work with and the technicians were very professional and kind. The work is quality, labor is reasonably priced and they leave you feeling like they will take care of you for years to come. Happy with Hiller for sure! Close

Nick and his assistant Matt did an amazing job! They stayed for 10 hours making sure the job was completely done right. Great company from start to finish. There were no hidden fees or anything to be worried about. I finally have air that cools down in minutes! Definitely my #1 place to call and recommend! Thanks Nick! Close
