My service was amazing. James was very professional and knowledgeable. He explained everything to me and answered all of my questions didn't take him long to complete the job! I would recommend James to my family and friends and thank you guys for your service read more

Good customer service. Technician was honest and explained things well. Quick response for maintenance service. Came out the same day

My parents are older and needed help with a lighting issue while I was away. I called Hiller and explained what the situation was with the possible electrical issue and also that they would need to speak with me about handling the service and payment. Roy came out really quickly and was able to figure out the issue and fix the problem. I was able to use a $50 off coupon that I found on their site. I would call them again for any future home problems. read more

Update** I was contacted by Seth the Client Relations Manager to resolve the issue and with his help we where able to resolve the issue in a timely manner. He sent out Kenny who did the work and was able to unclog the septic pipe the next day. Thank you Seth and Kenny! I will update if things change with the septic pipe. Also I gave a 4 star because I believe that I should not have had to go through this issue in the first place. read more

Great job at a fair price. Jacob did a great job. Jacob was very friendly and knowledgeable

Contacted them back in march 2026 about a hvac issue, tech showed up and stated would have to order the part which would be in the next day and they would return to finish the job. The tech never showed up or contacted me, I left a review and a higher up from Nashville to contacted me and offered a full refund and a 12 month free maintenance offer. I accepted the refund and the 12 month service offer. Today 6/9 I got a email saying I need to schedule my first maintenance so I scheduled one for today at 4 PM. It is not 5:45pm and no contact from anyone. not Sure what's up with this company but ended up using a local "family owned" company for service and repairs. read more

Great service: polite, professional, timely and comprehensive. Thank you Beau and Hiller

I have used Hiller for plumbing service twice. Both times were great. I love that you can schedule online or by calling. They arrive on time and are very professional and the price is reasonable. They know their stuff and are very upfront and honest about what needs to be done and the cost. They show you before and after photos when they're finished. Overall, I've had an excellent experience! read more

James was our technician today, as our central air was not working. As I have always experienced with the Hiller family of technicians and customer service folks, he found the issue and took care of it in a very short time. We are once again cooling down in this heat wave and I always find myself in the 'Happy Hiller Club' and so proud to be a customer! Thank you again to James and the entire Hiller company for making us feel like #1! read more

Hiller has always serviced my HVAC, plumbing, and electrical equipment. They are professional, honest, and reliable. I highly recommend!!

Great service and the techs are knowledgeable. The membership is worth every dollar.

The technician, Rocky, did a fantastic job working on my HVAC. He's so thorough and so organized and such a perfectionist in his work. I feel much safer now. read more

Good service with high quality knowledgeable technicians. Very good communication with the scheduling department. Used them for 12 years now and very satisfied. read more

Randy at Hillers AC service completed the project in a timely, professional, clean manner he was very knowledgable and prompt I plan on get the Hillers membership soon. Family owned business. I highly recommend Hillers Service. Huntsville AL read more

Plumber service by Shane was excellent. He explained thoroughly what the problem was and how he would fix it. He was able to obtain all the parts he needed for same-day service. The repair and replacements were done quickly on two different leaks we were having in two different bathrooms. He was here less than an hour. We were very pleased with the quality of the service, the courtesy he showed and the cost. read more

Hiller always has provided us with terrific service. They installed our new A/C unit, and more recently they solved an issue with our Clothes washing machine drainage. I highly recommend them to anyone who needs help! read more

Hiller and team (James) are always on time, professional, and knowledgeable on what's needed to make the repairs to my home. Thank you so much for your service! read more

Hiller is a great company who works with Helping Hands and Habitat for Humanity. They show up on time and have very nice people. They installed some AC equipment for me and I'm very pleased with their work. I also found out that they have a program to help transition military to the trades. read more

Outstanding service by technician Mr James Keith , young man was very professional and very knowledgeable, would definitely recommend.

I'm a disabled Iraq veteran. When my old HVAC bit the dust I was recommended an independent veteran for veterans contractor to help rectify the situation. Turns out it was a scammer who wasn't licensed, never fully installed the unit, took my money, & ran. I called on Hiller to help me to complete the installation of the unit I was left with. The technician they sent out did an initial inspection, & when he called it in to his higher ups about the situation they told him, "NO! Don't touch it. Tell the guy to keep calling the guy who scammed him to complete the installation." They literally told me to keep calling on a guy who had robbed me to complete the job. That's the compassion you can expect from Hiller. read more

Imagine this I buy a hot water heater from you - $4,000 less than a year ago. Due to your shotty install and finding out the hard way you did not insulate the pipes they burst.... During the freezing temps and flood your garage. And now you have no water at all due to the location of the pipe that burst. And the soonest you can get someone here is tomorrow night. Oh did I mention I pay $20 a month for servicing? oh and let me not forget the 15k spent on an hvac unit that you didn't bring a refrigerant line up to code that blew? And now we have a half ass welded hole in our 15k system? DONT CHOOSE HILLER read more

Our AC was getting quite loud and had not been serviced in a couple of years, so I decided it was time for preventative maintenance before our summer heat. I called Hiller first based on their reviews. Good move. Everyone was very professional, from the first call through the end of the project. Eric came out the next day, did a full inspection and offered some suggestions. Absolutely no attempted hard sell, or attempt to sell anything. What most impressed me was his pride in working for Hiller, respect for their training system, and respect for the owner. I decided to check the cost of a complete replacement and a project representative, Corey came out. He had the same attitude as Eric, and we negotiated a very fair deal. Three days later, JR and his crew arrived with my new system. Polite, professional, well trained. You have to respect a company with so many people who are so happy and proud to work there. read more

We had them out to clear backed up drains they charged us $199.00 and the next day they were backing up again. They did come back and clear them at no additional charge and we got a quote for a repipe. Needless to say they backed up again so we called a different company and paid another $200.00 and had them give us a quote which was a LOT less than Hiller, we are doing the repipe and new water heater with this other company. read more

Called for a bid and they arrived on time. From the start it felt like a sales pitch to sell me a tankless water heater installation. For $6400. I really wanted a conventional tank heater. The tankless brand is $1500-2500 cash and carry. Bid had Romex at $7 a foot, iron pipe at super inflated prices. Took three days to get back to discuss bid. I had already hired other qualified providers at much lower price by that time. these guys might do a great job but way over priced. Shop around. Plus the guy that finally called me back to answer questions got rude when I told him why I was going elsewhere. read more

My electric panel blew up at 5:30 in the afternoon. I was able to schedule an appointment for the next day at 5-7 pm. But Hiller was able to get an electrician here in the morning instead. The electrician that came to my house was Roy Hastings. Head very kind and polite. He did an excellent job replacing my electric panel. I will call Hiller for any plumbing , electrical or HVAC issues I have. read more

I would not recommend Hiller to anyone. They have come out numerous times to my house and they have had to redo things more than once. They are extremely expensive and to be honest I don't think they always know what they're doing. They like making excuses for things they don't do correctly. read more

See all

Wonderful company and I called around to several places and this was by far the cheapest to get my A/C looked at. He got it up and running again in a short period of time, he also did not harass me to buy anything or make me feel obligated to do this or that. He understood I needed to speak with my husband before decisions were made. I respect that so much because it makes me as a customer feel better about the decisions I'm making. They also send a text and email for an appointment reminder. Call and text when the technician is on their way. In the text you receive the technicians name and picture as well so you know who you're letting in your home. I want to add I signed up for their Happy Hiller Club also and got 10% off as well as diagnostic fee waived. For $23 a month they'll come out twice a year to check the A/C and heat and once a year to check the electrical portions of my home and do a tune up and once a year to do a tune up of all of my plumbing including emptying my hot water heater and clearing all of the sediment out. There is no diagnostic fee and you get 10% off of whatever they do. You earn $100 a year in hiller cash that you can accumulate and say if you keep the contract with them for 10 years you have $1000 saved up in Hiller Cash and you need a new A/C unit you can put that $1000 towards it plus the 10% off. Oh and you get priority scheduling because your a member read more

Call to get electrical quote. Explained that a wall was removed and I needed outlets moved and added. The tech arrived and said he needed a permit to perform work. This was not explained when the appointment was scheduled. I was made to pay for he service fee and no quote was given. They need to train their operators on the business to avoid wasting the consumers time. When my contractor arrives next week I will not be calling happy Hiller (mad consumer) to do the work. read more

Hiller can be pricey, but they can always get us in quickly and do great work. If you're having major work done and you have time to price shop, you might want to get a few quotes just to compare; however, overall they are a good option. read more

Great team of young men installed my new HVAC system today. Professional, knowledgeable, courteous group that cleaned up after themselves. Thanks Dylan, David and Adam on a great install. As for my new system, well it looks pretty and seems to be working great. Let's see what happens. read more
