NOBODY is eager and happy to call a plumber for a stopped up kitchen drain. That said, this experience was OK. James, our Hiller team technician, called ahead and arrived on time. He explained what he was going to do and set about doing it. I have never before seen a PVC pipe from the inside. When he was done we discussed what he had found and possible next steps. He demanded payment. Good job. Good work well done. FIVE stars!! Close

Hiller was able to come out the same day to see about a malfunctioning sump pump. They were actually about an hour early. John was not able to fix my problem that night but was able to get the pump drained. He also took care of some other issues I had. John got me on the schedule 2 days later for a Saturday morning appointment with Aaron to replace my sump pump. Aaron showed up on time and worked til everything was complete. I would recommend John and Aaron! Close

We called and they came in a reasonable amount of time. The first technician assessed the problem and showed us pictures of what was wrong. He was very friendly and knowledgeable. He called the Project Manager, Brandon, and he helped us strategize and worked with us to get a new unit. He was very kind, he saw that we had no air downstairs, so he brought a mobile unit until we got the unit in. The guys who came and installed the unit were friendly and efficient. Close

First time using Hiller and I could not be more complimentary. They were at our house within an hour after first being called on a Saturday. Jared was excellent. He was friendly, competent and wanted to make sure the job was not only done, but done right. He and Hiller went above and beyond and I’m happy to recommend them in the future to anyone. Close

For the second time now Hiller has saved me after hours!

I am a member and use Hiller and have for 8 years. I have had a couple issues but not about the service they give me. They are always prompt and they don’t waste time getting to my issues. Today I had Manny and he was very professional although he is a plumber he checked an issue I was having with a couple plug-ins and even called Hiller when he couldn’t find issue and got me scheduled with an electrician to come check it. I have found they go beyond to help. Close

Unfortunately I had a 2-ton unit go bad recently. Austin Irby was very professional and did an excellent job diagnosing the problem. He then had me setup the next day with a visit from Shannon Fish to quote me on a new unit. I had 3 companies come give me estimates and Shannon was by far the most professional and thorough. Finally, installation of the new unit was done by lead installer Joseph Fox (assist from Dean). Both did an excellent job on the installation/test. Overall, working with Hiller was an excellent experience. Close

We're Hiller Club members for years now. Recently, we had our annual plumbing checkup and had a slow drain in the main bath. After a bill over $283 dollars the drain actually flows slower than before they "fixed it." Had to call someone else who actually took the time to correct the problem. Sad customer who's out twice the cost. Update: I have amended my review (from one star to 4) due to a timely response and a full refund promised by Hiller Plumbing. I'm feeling much happier now, and I plan to continue my Happy Hiller Club membership. Close

We’ve called Hiller a few times over the last few years and they have been fantastic every time! Their service folks are super professional, fast, and have helped us understand the ins and outs of our issues. They understand the situation is usually unpleasant. This most recent call for us was for our A/C going out. They got us in diagnosed and a new unit installed in less than a week. By the way, if you’re looking for a new unit, you should talk to Quintin Busher. He’s great and he’ll make sure you’re taken care of! Thanks, Hiller! Close

Amazing client care from start to finish. We had an issue with our plumbing around 8-9pm and I called hoping to get someone out but figured it would be next day service. They had a plumbing professional at my house within the hour and got us taken care of. The client care was amazing, took every detail & actually listened and the technician was very prompt, knowledgeable & kind. Really appreciate each person I dealt with being very professional & able to come out so late!!! Close

My husband accidently dropped his wedding band off his nightstand which flew into the floor AC vent. We called Hiller company and they sent out an exceptional person, Spencer. He worked diligently to get my husband's wedding band and was successful in getting it out of the AC vent. Would use Hiller again for any other work that we may need at our home. They were on time and clean and very professional! Thank you Close

They came within hours, on a holiday weekend, to fix a major water main leak another plumbing company had been unable to repair. They gave an honest assessment of the problem, their recommended solution, and arranged a quick appointment to remedy things. They also provided a temporary solution to get my water back on until they could do the final work. So very thankful for Hiller Plumbing! Close

We used Hiller for a total home repipe and they took a lot of care with the process. We are super happy with the end results and while we do have some dry wall repair they definitely did great to make straight lines to make repairs easy! We had Austin, Charlie, and Q come out and they did such a great job. My clean up was very minimal and I could tell they took great care with everything which I appreciated. I have two small daughters so keeping a clean home is important to me. I am so grateful to be a “happy Hiller” and would recommend them for plumbing services AND HVAC. Close

I have used Hiller Plumbing & Electrical quite a few times this year, starting with the installation of a water filtration system to now having my sink uninstalled and reinstalled and in between fixing a few leaks and checking over the general plumbing as well as electrical outlets in my house. Throughout all of it, a couple of glitches arose, but they more than made up for them. I am totally impressed with their professionalism and wanting to make sure everything was perfect and just the way I wanted it! The Customer Service is amazing and the workers are professional, capable, and friendly. I couldn’t be happier! Close

The technician Jacob was excellent. He was courteous, knowledgeable and did an outstanding job in a timely manner. I was taken aback when charged a $99.00 fee for Non Truck Stock Sourcing (which I described to them with a picture of the switch when scheduling) and $25.50 for Non Truck Stock Material and $99.00 Switch or receptacle replacement for a grand total of $223.50 for the job of replacement of a light switch. The services were quite expensive. Close

Excellent response in emergency and Jack was professional and efficient. The charge of $179 to flip a lever on my cutoff valve in a space that was approachable on foot (no crawling around to get to it) was outrageous but I had no choice. I will forever resent that charge but all else was the usual good service and reasonable repair charges for a work-in call for a Saturday emergency. Now that I know where and what it is I will turn the intake off myself if the need ever arises. Close

Our AC stopped cooling in the middle of the night. I contacted Hiller the next morning. Haleigh was extremely helpful in getting us scheduled for same day repair. Lance got here earlier than expected and immediately found what the issue was. He was very professional, courteous and efficient.

Woke up in the morning to find out I had no hot water. Thinking my pilot light was out, I went up into my attic where my hot water heater is located to relight the pilot. To my surprise, not only was the pilot light out, but I had standing water in my drip pan and a flowing leak from my temperature relief valve. Knowing I needed immediate help, I scheduled an appointment with Hiller online around 7:30 AM, and by 1:00 PM, William Gough arrived at my home to assess the situation. He quickly identified my water pressure was extremely high (120 PSI) and explained I needed to get it fixed immediately, not only to solve my water heater issue, but to prevent any further water related damage that could occur with that high level of pressure. He mentioned he could schedule a new heater to be installed if I desired it, but thought it might be possible to flush it and get it back into working order instead of replacing it, especially once I had my water pressure issue taken care of. He scheduled his team to come out to further evaluate and perform the required services. Later that day, Frank Croce and Chad arrived at my home earlier than their scheduled time. Upon further inspection, Frank found that water and sediment had already damaged the water heater insulation and its bottom (see photos), and he recommended a full replacement - he and Chad could do the flush and repair on it, but I would be on borrowed time before it started leaking again. I took Frank's advice and went ahead with replacing the water heater. Frank and Chad immediately got to work on installing my new water heater, as well as replacing my pressure regulating valve on my main water line downstairs to solve my water pressure issue. Within a few hours, they had me all fixed up (see photos of new water heater and PRV). I now have 60 PSI water pressure, hot water, and most importantly no leaks! Frank, Chad, and William were an absolute pleasure to work with and I truly appreciate all of their help. I'm extra appreciative because I understand working in a hot attic is not easy or comfortable, and not once did they complain about it even though they had every right to. All of these gentlemen went above and beyond the call of duty and deserve recognition for it. As a first time customer of Hiller, I was extremely impressed and will most certainly be calling on them for other services in the future. I hope Frank, Chad, and William will be the ones helping me again as well. Thank you, Team Hiller! Close

This is the first time I have done business with Hiller but will NOT be the last. I’ve had to have my heating and A/C completely replaced. Hiller to the rescue !!! They came, checked the situation and within 3 days, completed the installation. I was in contact with so many different people and I want to name each one because they each made it possible to get this done. There was Alex, Charlie, Dustin, Logan and Darren and not to forget all the woman who talked to me on the phone. They all were wonderful and the customer service is outstanding. If you want excellent service just call Hiller. Oh and don’t forget to join the Happy Hiller Club, you’ll be glad you did. Close

Technician, Tommy, was extremely professional and knowledgeable about the installation and operation of a much-needed hot water circulating pump. He redid several aspects of the existing plumbing ensuring a successful and purposeful install. He fully explained the need, cost, options, etc without employing any pressure tactics. Very refreshing to works so diligently for a customer. His integrity, honesty, and ethics will undoubtedly lead me to use Holler in the future and, if possible, Tommy as the visiting technician.
