Jacob and Quez did a phenomenal job! I bought a new hot tub and needed an electrician to install the 220v electrical box and wire up the tub. They did a great job. They did a great job running the conduit and everything looks nice and clean. They take pride in their work and it shows. When they were done, they showed me what they had done and we fired up the hot tub to make sure everything was working. Not only did they do a great job, they were just a couple of nice guys. They were very friendly and easy to talk to. It was clear they enjoy what they do and that they are good at it. I would not hesitate to recommend either of them. If the day comes I need an electrician again, I hope one of them will be the one that comes out. Close

We recently had our HVAC system (indoor and outdoor units) replaced by a fantastic duo team from Hiller; Nor and Anthony. Both technicians were very knowledgeable, thorough, and professional. The outdoor unit required leveling of a new base before replacement. The indoor unit required a challenging replacement on the second floor inside a restricted storage/access area. Both replacements were completed thoroughly and professionally. The after testing was impressive and attention to detail was noted. Both technicians kept us updated on the job's progress start to finish. Shout out to Anthony's base leveling landscaping and Nor's insistent drive for an outstanding job completion. Considering the event began with a heating issue/prevention checkup of our over 18 year old system and the interaction with the project manager Dave, we are more than satisfied! Kudos to all involved and thank you Hiller! Update: Many thanks to Solomon and Kirk coming out the very next day for a final checkup and inspection. Combined, these techs did an outstanding job of insuring all was properly installed. Our HVAC setup is running great! Close

A tree limb fell across the power lines to my house. The force pulled the wires loose from the electrical panel. I knew this was serious and needed experienced people to repair it. I called Hiller early Monday morning. The person who I talked with understood the seriousness of problem. She assured me that someone would come to my house that day. Jacob came to my house later in day. He was very professional and immediately began assessing the problem. He told me that it needed to be repaired immediately. He talked with his manager, who agreed with his assessment. Hiller contacted my power company to turn off the power to my house. Jacob gathered up the needed equipment and went to work. Jacob was a very experienced professional and a really nice person. He kept me informed during the night. When he had repaired the electrical panel and wires, he notified my power of company to come to reconnect my power. I highly recommend Hiller if you need help any electrical needs. Close

Wow! I just had the best encounter with service technicians I have ever had, and I am 75 years old. My HVAC system stopped working so Sam came out to work on it. He brought in Dave because of both the age of my system and the high cost of repair. I opted for a new system. Again, WOW! A great deal on a new install, thank you Dave! Dustin, Jeremy and Tre came to do the install. Great guys; extremely professional, personable and most importantly - they cared! Happy Hiller has made me happy! Close

The folks at Hiller did an awesome job in replacing our furnace and AC unit. I had another HVAC company out twice to diagnose our furnace. Both times that company failed to correctly assess the issue we were having. They had no problem charging with the service call. Hiller responded and provided us with information, so we could make an informed decision. That decision was to replace both the furnace and AC at the same time. Within several days, we had the new unit installed by a very courteous, competent, and professional crew. Noureddine and the other install crew treated us very well and we feel confident we made the right choice in choosing Hiller. Hiller was recommended to us by a neighbor and I can unequivocally recommend them and their employees who obviously show pride in a job well done. Close

I am very pleased that Hiller coordinates house projects with a project manager. Hero Services did NOT do this for the 12 years I was with them. Bryan was the project manager. Brandon, Jacob, Andrew, Greg worked hard to address my many questions and the electrical issues of upgrading from fuse box to breaker box. They were patient and willing to teach and explain what they were doing. They were interested in getting it done right instead of done fast. I was glad to have it done with care, and with the work guarantee. Close

Giving five stars to Brandon and his partner for coming today, 3 days after Stephen installed new electrical panel and left wires exposed that State Inspector also saw yesterday and did not approve either. I called Tuesday after crew left stating wires are exposed to crawl space and didn’t look correct and was told they’d come back Wednesday. Nobody came. I called again. Was told he’d come today between 1-3 pm. Nobody came, I called again. Finally, Brandon and his partner arrived later today and corrected the issue and also took time to take off surge cover and hang correctly. We had to ask what that box even was as Stephen did not show us anything and we didn’t know why that box was installed too. Warranty paperwork? Not sure we got that either. We went above and beyond to show southern hospitality to Stephen on Tuesday as we do for anyone we have to call to work in our home because we appreciate the service, but this was ridiculous service.. He failed to show us his work and seemed hurried to leave around 2 pm that day. If he had been more professional and thorough, the last three days of frustration might’ve been avoided! Brandon and his partner worked well together, and they are a valuable asset to Hiller and need to be praised for their much appreciated care and concern. We are on a budget as most folks and just want what we paid for to be correctly installed and worth the cost. We Will request Brandon to come if we need electrical help in the future, but we hope we won’t need to call. Close

They had Jimmy Tidd at the house within a couple of hours. He promptly called to tell me about what his arrival time would be and called me again when was 20 minutes away.

Teddy came to our house on a Saturday after we could not get our A/C to turn on after a recent storm. Upon arrival, Teddy listened to the history, inspected the unit and gave me his preliminary thoughts. After completing a thorough inspection, he provided me with a detailed plan, an explanation of why the plan was in place, and then how much it would cost to execute the plan and fix the A/C. Once the cool air was in our house, Teddy continued to test and stayed to make sure all was functioning well.

Had my split unit put in in no time. I will do business with them again. I will recommend them to my friends and family for sure! Thanks for the awesome Job guys! Close

If you're looking for a company who is going to listen to your needs and your wants and explain things in a way you can truly understand, then Hiller is who you want!! Justin came out to look at our unit, explained to us exactly what the problem was, and had Brian come out to give us the best deal we could get in replacing our whole 2007 unit. Brian was incredibly helpful and heard everything I was saying and helped get us into a new unit with all the safety features our old one did not have! He had Dustin and 2 other guys with them install our units and fix our ducts, they were so clean throughout the whole day even though it rained the whole time they were here!!! We are very impressed with this company and will be using them for all our future HVAC issues and plumbing!!! Close

After years of power outages and putting off getting a standalone generator I threw in the towel and started the endless research to find a reliable generator I was willing to invest in. I finally settled on getting the Kohler 26kw standalone generator. It bubbled to the top for reliability and quality over Generac and Briggs and Stratton. Next step was to find a contractor who was experienced, reliable, licensed, and trained to service Kohler generators. I had three bids and Hiller was the winner in terms of price point and after purchase care. Project Manager Bryan Johnson came to my home and very patiently and thoroughly explained everything from operation to maintenance about the Kohler generator I wanted. I’ve never owned a standalone generator and I had a TON of questions! Thanks, Bryan for your patience! The crew that came out on time on installation day was amazing! I had no idea how complex and labor intensive it is to install a standalone generator! Kurt (lead), Brad, Hunter, Daryl and Justin were buzzing around like bees for 12 hours solid (I had ask to see if they even took a break to eat). Their work was professional, quick, efficient and it was amazing to watch them work. And again, while all of this was going on, yep, you guessed it, I had questions. They patiently stopped and asked every single question I had no matter what. Thank you so much guys for putting up with me and being so patient! Buying a generator was a HUGE investment for our home, and I was very nervous about the whole process. But I can tell you without a doubt, my fears are no more in the hands of Hiller! Thank you so much for accommodating this nervous client! Go with Hiller! You can’t go wrong! Close

I had a work issue with a stopped up drain line. Nobody could get to us in a timely manner, it was going to be an after hours call and estimated to be around 6-7 PM. I received a phone call at 3:08 PM from Jared at Hiller Plumbing. He told me he would be on site in 30 minutes and almost exactly to the minute, he arrived at 3:35 and within an hour he had fixed the issue, double checked his work and also gave me some advice and pointers that would help in the event this issue ever arose again. He cleaned everything up, made sure i was happy and satisfied with the work and was out of my life, at least for now. Pretty sure I will be seeing Jarred and Hiller plumbing again in the future. Thank you Jared for your professionalism, courtesy and overall general delightful demeanor. It was great working with you and hope you have a happy Easter. Kudos to you, Hiller Plumbing is definitely a better place with you, God bless you all!! Close

Both men were very friendly, professional and knowledgeable. Close

Hiller Plumbing, Heating, Cooling, and Electric should be your only source for any of the services they provide. Throughout the process of our recent experiences, they have demonstrated, across all contacts, a culture of excellence and attention to detail so often lacking these days. Our most recent service project was a complete interior water line replacement. From the first scheduling contact to project completion, the attention and responsiveness of all Hiller employees assured us we had made the correct choice to complete this work. Will Hiller be the least expensive for your repairs or project needs? Perhaps not. Will they provide unmatched quality service, customer service, and attention to detail throughout the process? No question. We will be returning customers as we partner with them along their service lines to maintain our home. We want to especially recognize the knowledge, expertise, and understanding of our need for detailed information our project manager, Deven Henderson, provided from start to finish. When we had a collateral concern regarding our electrical system, he reached across the Hiller network to provide a timely and necessary answer. Need plumbing, heating, cooling, electrical service for your home. Contact Hiller. You’ll be glad you did. Close

Hiller just installed a generator for our house and they are amazing! We have been using them since we moved here and are always so happy with everyone that works for them. Always professional, great at walking us through what was done, making sure we understand and allow us time to ask questions, and making sure we understand proper maintenance to avoid future problems. They are all fast and efficient, but most of all careful, safe and so nice and personable. They also installed 2 lights in our kitchen and made no mess, made sure all bulbs worked and they disposed of the old lights so I didn't have to! I can not give them higher praise and thanks for taking care of us! Thank you all so much! Close

Prompt, same day service even though we called at 5 pm when our water heater began leaking. Our technician, Ron Wilbar, was professional and knowledgeable, arriving wearing an official uniform (comforting when it’s evening) and driving a clearly marked Hiller truck that was clearly labeled and had everything needed to address our needs - including a new hot water heater so we didn’t have to wait days to be able to have hot water. He gave us choices based on our particular needs - not price. He even took a look at other plumbing issues we were having and gave us recommendations on price shopping parts needed to get the best deal. As soon as the new garbage disposal and faucet set arrives, we will definitely be calling Hiller and asking for Ron to come back and install them for us. Close

I had an emergency situation with a busted hot water tank on my second floor leaking into the downstairs bedroom at 5:30 am with guest expected that evening. Called at 6 am and the answer service was responsive, professional, polite. The local office contacted me upon opening was again, responsive, professional, polite and very knowledgeable about coordinating the scheduling to ensure as quick of a response possible. Then, the plumber, John contacted me via phone with an ETA, he was so confused prepared with everything needed to resolve my disastrous plumbing problem. He identified it, gave me a detailed quote, explained everything, fairly priced the job at hand, was competent (which these days seems hard to find), courteous, worked extremely well with his associate, left the job site cleaned with my home prepared for my house to have running hot water.

Two hours after posting the following review, I received a call from Hiller asking about my experience. They then referred the issue to the General Manager of our local office who reached out to me on the same day. He apologized, and agreed that their minimum charge for service in this case wasn't fair. We then arrived at an equitable figure, and he agreed to adjust my charge. I really appreciate them following up with me, and making a sincere effort to make it right. They were very professional, and appreciated my feedback as I believe their goal is to learn from each comment - good or bad. I'm feeling much more comfortable being a member of their maintenance club having witnesses their commitment to customer service. By the way, they never asked me to change my review - I'm doing this of my own volition. Originally the review below was a 3 star - after my experience with them in resolving this, I changed it to a 5 star review: "Joined the Happy Hiller maintenance Club. Had an HVAC inspection and a very nice technician did a great job evaluating our system, and found we had a tear in one of our ducts, and heat was spilling into our attic. We have a home warranty, so we asked him if he could fix it temporarily - and he said he could. It only took him about 10 minutes of labor, and some duct tape - the charge? $269.00 - at that included my discount for being a member of the maintenance Club. You be the judge, but I personally feel like that charge for the work performed was exorbitant. Didn't feel any customer loyalty for my 1st experience with this company." Close

What a relief! My wife and I set out yesterday to change out our electrical outlets from the old almond colored '90s ones to more modern colored ones. After fidgeting with one for about 2 hours we realized we needed help. We called Hiller the next day and just a few hours later they showed up! "Quez" Johnson sped through our kitchen replacing seven outlets total and did a fantastic job! He was even patient with me coming and going from Home Depot to get a few things I forgot ?. I'm glad we got a professional for the installation. Who knows how long it would have taken to do all those outlets ourselves and if the house would even still be standing! Will be working with them again soon in the future! Thank you Mr. Johnson! 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

From start to finish this company was great! The project manager Shannon never tried to over sell or push upgrades that we weren’t comfortable with. The techs that installed the unit were friendly and great with our dogs. The plumber was quick and polite. All around, couldn’t recommend this company enough. 10/10 Close

Jarrett was outstanding! Not only did he repair the leak in our crawl space. He photographed the damage. Set up the company to make repairs to the wood joists. Holler will have a project manager come out and give us an estimate to replace the 63 years old copper pipes. Happy to be a Happy Hiller customer! 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

Electrical lighting upgrade and repair. The technician, Jacob, determined the ballast for my kitchen light fixture had burned out. He told me my options (replace the ballast or upgrade to an LED) and explained the cost for each. He accomplished the repair immediately and departed an hour after arrival. Friendly, knowledgeable, and efficient. I am very happy with this service. 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

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. He didn't leave until he made sure the capacitor he replaced completely solved our issue. I highly recommend Hiller and will definitely be using them again in the future! Close

Ryan was great! He was on time, diagnosed the issue quickly and took his time while fixing. He explained everything along the way and even told us about Hiller's tune up service. Simply because of Ryan's concierge level service, we will use Hiller going forward. Pricing was very affordable and saved us the pain of having to self diagnose and fix! Thank you, Ryan and Hiller!

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

Hiller was fantastic to work with. Joseph was top notch. He was early for the appointment. He diagnosed my problem in a few minutes. Left to pick up supplies and within an hour was back installing my new hot water heater. High quality work. I will definitely call Hiller again for any other future problems. 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.

Hiller was my first call when the attic A/C was dripping water down through the duct work. They got to us same day and were prompt and professional. Lance was an awesome technician. Polite, professional and thorough. I appreciate that he took the time to educate me on how to prevent this from happening again. Hiller earned my business as my go-to. Great Work! Close
