HVAC reviews in Birmingham, Alabama

Shane with Hiller fixed my plumbing issue in the middle of the night. He was very professional and courteous. Shane took time to explain the underlying problem and how to prevent it in the future. Very reasonable price. I would highly recommend Hiller.

My whole toilet was overflowing and I’d gotten a few quotes from other people to fix it but the prices were through the roof. I got in contact with Hiller and a guy named Justin Armstrong came down and fixed my whole issue. I was extremely thankful, he did a great job. He was very friendly and got the work done.

I had a clogged sink and got this company to fix it for me. Justin Armstrong is who came to do the job, he was very professional, friendly and got the job done. It was AMAZING AND QUICK! Great prices too! Good place to hire for any tumbling issue!

Reid was great when I was looking at new systems. When it’s time, I will definitely be contacting him & Hiller! Thanks a bunch

Logan did a great job. His HVAC knowledge and skills are superb and I highly recommend him. I will request his services in the future

Truly exceptional service. They were able to get me booked, fixed, and finished within 8 hours on Christmas Eve. Could not have asked for a better job.

I have to say this is my first review but I just felt the need to share my experience with a company in the local Birmingham area recently!

You know how sometimes you just know you’ve found "the one"? That’s how I feel about Hiller. I’ve gone through my share of companies—the good, the bad, and the just plain forgettable—but Hiller is in a league of their own. I'm not just satisfied; I'm completely blown away.

From the moment the technician stepped through my door, it wasn't just a service call; it felt like a family member had come to help. The knowledge and expertise were incredible, but what really got me was the heart behind it. They don't just fix problems; they genuinely care.

The GM told me they're trying to set a new standard in the industry, and they would do whatever it takes to turn the heads of the people and show them that there is 1 company in town you can always call and feel confident about….and wow... he wasn't kidding. The passion they have for what they do is contagious and, frankly, unheard of. You can feel it in every interaction. They don’t see you as just another job; they see you as a person they can help.

Take it from someone who has been through the ringer: if you need anything—plumbing, electrical, or HVAC—don’t waste your time with anyone else. Hiller is the real deal, and I can promise you, once you use them, you will never, ever call another company again.

My technician was kind, knowledgeable, and worked quickly to resolve my issue. He not only fixed what was currently wrong, but explained the problem to me and let me know of problems to keep my eye out for in the future. I will definitely be using Hiller in the future and highly recommend them.

Justin was friendly, fast and efficient. He performed a thorough inspection of my plumbing system and was able to do needed repairs the same day. Very happy with his service.

I had an excellent experience with Justin Armstrong from Hiller LLC. He came out to inspect a water leak at my home and was extremely professional, knowledgeable, and thorough throughout the entire process. Justin took the time to explain his findings clearly and gave me helpful feedback and options on how to address the issue, which I really appreciated.

What stood out the most was how he kept me updated step by step—making sure I understood what was going on and felt comfortable with the process. On top of that, he did a fantastic job replacing my dryer line. The work was done efficiently, and the quality speaks for itself.

Justin went above and beyond, and I couldn’t be more satisfied with his service. I highly recommend him and Hiller LLC to anyone needing reliable, skilled, and customer-focused service!

We’ve used Hiller twice for different issues and both times they’ve been great. Our most recent technician Logan was very professional and a delight. Thank you, Logan!

Darrell was very helpful, quick, and informative. Hiller allowed for us to make an appointment for day of service and got our issue fixed.

I was having an AC issue and needed help (fast). I called Hiller and they quickly sent out a technician and a sales representative because the repair almost exceeded the cost of replacing the system. Both gentlemen spent time explaining everything to me about the issues and about a new system. I really appreciate their assistance.

Do not hesitate to call them if you want quick, friendly and knowledgeable service.

The system I chose was installed the next day by a courteous and professional technician.

Thank you, Hiller.

We will absolutely be using Hiller again - such a seamless process from customer service intake through the technician completing services. Never have I experienced an enjoyable plumbing service, and this was exactly that!

Hiller Company in Birmingham did an exceptional job resolving our HVAC issues. From the manager and office staff to the technician, everyone was professional, courteous, and committed to quality work. Special thanks to technician Richard Holtzman for expertly repairing our system, and to General Manager Cason Carroll for his excellent leadership and oversight. I highly recommend Hiller Company for their outstanding service and professionalism!

Hiller Plumbing Technician Alex Ritter was on time and ready to work. Professional, knowledgeable, honest and pleasant. In a world full of slackers and hacks, I am thankful for Hiller sending Alex to my home. Strong recommend calling Hiller and asking if Alex Ritter is available to help with your plumbing needs. RM

This company went above and beyond for our family. The customer service is absolutely excellent. Their technicians are polite, friendly and truly genuine. I cannot recommend this company enough. They see you more than a customer. They see a person, a family, a need. They provide amazing service and are very professional. I'm honored to have had them install our system.

I had an excellent experience with Alex Ritter from Hiller Plumbing, Cooling & Heating. From start to finish, he was professional, thorough, knowledgeable, and genuinely friendly. What stood out most was his honesty — he took the time to explain everything clearly and never once tried to sell or pressure me into unnecessary parts or equipment. That kind of integrity and transparency is rare these days and truly appreciated.

Alex represented Hiller exceptionally well and left me with full confidence in both his work and the company. I highly recommend requesting Alex if you want quality service done right the first time.

Alex from Hiller Plumbing, Heating, Cooling & Electrical did an outstanding job getting my gas logs up and fully operational. He was prompt, professional, and clearly knowledgeable about the system. He explained everything in a way that was easy to understand and made sure everything was working perfectly before he left. Excellent service all around — I highly recommend Alex and Hiller Plumbing, Heating, Cooling & Electrical ! Thank you, Alex!

Woke up this morning to a large leak in the basement, and am so grateful Darrell and Landon were able to take care of me so quickly. Darrell quickly diagnosed the problem, communicated wonderfully, and was able facilitate getting a new water heater and installing it during one trip. Thank you for being so efficient, knowledgable and easy to work with - adeptly finding a solution to a very stressful problem. Would definitely recommend Darrell and Landon from Hiller plumbing!

Hiller has been one of the best companies I've ever hired for anything household related. They have come out to work on my system for various things and are always extremely professional. I have to give particular recognition to Logan Currier. He is the friendliest and most respectful person I've ever had in my home. Not only does he almost immediately deduce what is causing the issue and repair it quickly, but he cares about the customers. Logan explains everything well and will show the customer what exactly is going wrong.

I bought my system from Freedom Heating and Cooling, from whom I have received extremely poor customer service, work that was lacking, and refusal to acknowledge my warranty. Logan went above and beyond to contact the manufacturer of my unit and verify that my warranty is current and valid. Talk about peace of mind! Additionally, he found that Freedom had not even hooked up either of my safety switches in the attic! By taking care of this for me, Logan may have potentially prevented a fire, flooding, or damage to my system! He didn't have to mention that and could've just called it a day, but once again he's going to look out for his customers.

He has never tried to sell me something I didn't need or take advantage of me like many companies out there will do. You should definitely request Logan for your repair work if you value transparency, honesty, excellent work, and being treated like a friend rather than as another job on the schedule.
