I have been using Hiller since I moved here two yrs ago. They have consistently been very pleasant and thorough. Always making sure everything is done correctly. I definitely recommend Hiller Plumbing Heating and Cooling. read more

I like to say Damien and Zyler were two most professional electrical technicians ever. Damien was very knowledgeable, proficient, courteous, and friendly person. Tyler was a fast learner and very calculated on performing his testing on the outlets and breaker box. If you are in need of an excellent electrical service providers DO NOT HESITATE CALL: HILLER PLUMBING, HEATING, COOLING, AND ELECTRICAL COMPANY. Be like me and get the monthly service plan and always be on top of things before a problem arises. THANKS HILLER. read more

GREAT JOB! Jason was very professional, courteous and completed the work in great time. I would highly recommend him!

Blake was very professional and informative today. I appreciate his service. Hiller hasn't disappointed me yet.

Andrew was great. He thoroughly communicated the issues with my appliance and gave me reasonable options to consider. I felt no pressure to choose any given option and did not feel like I was being "sold" anything. He was respectful of my property and my time and made what could have been a stressful situation much more pleasant to deal with. read more

Hiller Plumbing Heating and Cooling were very polite and informative. Will request Jeffrey Tye again.

I have been a Hiller customer for 6 years since buying my $12,000+ HVAC and water heater, and paying $300 a year to be in the "CLUB". The last 3 times they have done seasonal maintainance on my system, they have had to come back and repair what they broke. This last time will be the LAST time. Over Easter weekend, I was sick and with 3 dogs in the house, and they broke my AC so bad that they had to give me two window units that ran 24/7 just to keep the house below 80 degrees, until they could get a part and do a temporary fix for the next 2 weeks. I still don't have the complete repair yet, nor do I have the electric bill for this month, but they will get that once it comes in. They also did my plumbing maintainence and never mentioned to me that I had a leak under my bathroom sink with corroded pipes. They took pictures of all the plumbing, just not at the right angle. I am now repairing my own plumbing for fear of what else they might break. I called 5 hours ago and left a message that I wanted a manager to call me back. No call yet. This is NOT a HAPPY Hiller customer. read more

See all

My service tech was Gabriel. He was punctual, professional and courteous. He explained everything that was going on, so I could understand. He reached out to another department and got someone (Adam) to come out same day to discuss pipe replacement. I called Hiller on Saturday re:clog I couldn't fix. They came out Sunday to fix it. My pipe replacement will take place next week. They may be a little more expensive but I can always get ahold of them and get them out to my house pronto. That is unheard of in my experiences. Thank you Hiller, Gabriel, and Adam. read more

Technician arrived on time called before he came and was very efficient in his work. Didn't try to sell me any crazy stuff either.

Technician Blake made an emergency call for a drain clog. He was knowledgeable, professional, courtesous and very personabl. Would definitely recommend this company and if you can request Blake, you won't be disappointed! read more

We're talking about greed here with Hiller Plumbing, Clarksville. I've used them before, and they were reasonable and did a good job. But with a simple job of changing a toilet valve and flapper that the technician, Tyler Gallant, said would take 15 minutes to do, he wanted to charge me: 1st quote: $552.40, without tax, and, 2nd quote (after blowing my stack with a few cuss words): $303.01. Neither quote included the trip price of $69.00, that I paid before throwing him out of the house. It's of interest to know that I went to Lowe's and bought the needed parts, retail, for $27.00. As American consumers, let's just say NO to the service industry ripping us off. As for Hiller Plumbing, Clarksville, I will never use nor recommend this company again. I called the company to complain, and the office person in Nashville, Jennifer, after leaving her a message, never got back to me. E. Marshall, Trenton, Kentucky read more

I had a water heater issues. I called at 0930 and Hiller got a guy out to my home by 3. Learned that it was an electrical issue with the breaker. Electrician came by within 10 min. Got the switches replaced. Quick service. read more

This review is for the Hiller Plumbing, Heating, Cooling Company. I called Hiller today, but I'm thinking they are in Tn. they don't do this area, but they came early, earlier than expected, and was here a little over an hour.  This man, Samuel, cleaned up after the mess was left by another Clarksville, Tn. heating company.  It took him less than an hour to connect the wires in the correct order where the others spent 6 hours playing with and still didn't get it right. Samuel looked professional, talked professional, and was intelligent.  He did what the others could not do in a total of 11 hours, in less than an hour.  And at 1/4 the cost.  They ARE the company to call. read more

Requested an appointment, they got back with me the same day and booked on the day I requested. Quality of care is always great and professional. read more

Always a great experience with Hiller! Our heater acted crazy in the middle of the snow storm and Hunter Adams, along with the customer service reps, and helped us out within the day!!! Highly recommend! read more

We jouned their little platinum club, and after spending four times as much on new water pipes that the local water company quoted us after the installation, we called them about our AC unit. They then told us that it was an old unit, it couldn't be repaired, and tried to sell us a new one for $10,000. We got a second opinion from a competitor, he refilled the freon in th unit, and it works like new. They aren't interested in helping their customers, wether they're in the "special platinum club" or not. They just want to overcharge and upsell at every possibility, and bleed people dry. I hate hiller more than any company I've ever done business with. Greedy, shady little thieves read more

Hiller has amazing customer service! The whole staff Is efficient, professional and friendly. We called them because no one else even wanted or could do the job. We had all sewage lines replaced under the house. They not only fixed the problem but also fixed other issues they seen that could potentially become a problem. They also cleaned under the house and replaced the plastic. I would highly recommend this company. Great job Hiller! read more

We are extremely satisfied with the service, quality & value we have received from Hiller. We now have peace of mind joining the Hiller Family. Big shout out to Senior and PJ (Phillip) for their timely, professional, knowledgeable, friendly plumbing service! read more

Tyler Gallant, he does plumbing and did an excellent job. He was fast and a very honest person!! If I ever need them again, I will request for him.. read more

My technician was Kenneth Trahan. He was extremely friendly and thorough. This was my annual heating system tune-up. Thankfully all checked out. He did make a couple of recommendations but was not a pushy sales person about it. I have been very happy with the service from Hiller and have been with them for a few years now. read more

We are very happy with Hillar Heating & Cooling. PJ came out today to do a plumbing inspection. He found the source of our backup and spent enough time to explain what we needed to know. Thanks, PJ and Hillar. Jimmy & Julie read more

Just recently became a Happy Hiller service member. I am retired and was a building maintenance person qualified in many of the services that Hiller provides. I'm just at an age where I don't want to do it anymore. Their people have always been professional in appearance and action and the prices are at an acceptable level for today's economy. read more

I called Hiller HVAC for our heating and AC unit, technician was at my office location before I arrived at 9:00 and said he had already checked system and the unit was blown and needed new one, sent another guy from Hiller to give quote new unit, ( neither one introduced there selves or gave me a card) I called another company to get a 2nd quote and they fixed it same day and it saved us $6000 Bob Mardis read more

I had Hiller come out and fix a leaking bathtub. They were only at my house for 20 minutes and charged me $450... that's absurd!

We moved to Clarksville in June of 2019. We asked our neighbors for suggestions for an HVAC company and decided to go with Hiller. We had a service agreement with them where they came out each year to check the heating in the winter and air conditioning ing the summer. A year ago their service man came to check our 2 furnaces. Long story short he told me that he had to shut the basement furnace off because it was a safety issue because the heat exchanger was cracked and the threat of carbon monoxide. He showed me 2-3 things it was doing to show that it was. He said someone from Hiller would contact me about pricing to replace the exchanger or the whole system. I didn't tell him that we had a home warranty and called them to have their contractor check it to see if it needed replacement. Their service man said that there was nothing wrong with the heat exchanger!! We have carbon monoxide sensors through out the house and we've had no problems. I called a new HVAC company to have the 2 furnaces checked for this season. I told their service man about Hiller. He said that unless we had the heat exchanger in question replaced, which we didn't, it looked brand new!!!!!!!!! Could what Hiller tried to pull be called consumer fraud?!! I have Hiller's email with their checklist showing heat exchanger condition "RED" and the flame condition being "RED" also!!!!!!!!!!!!! I would post this but there is no option to do this. read more

Bought a system for both our upstairs and down, and we were drastically overcharged. My fault, I should have done my homework. 30 days in and my upstairs unit goes out. We've waited multiple days where our indoor temp has been 94+. "Happy I'll be or my service is free", I'm not happy with any aspect of my experience with Hiller. read more

The fact that you wanted to charge $700 to fix a water leak that took maybe 2 $40 sharkbites is TOO excessive in my opinion and a rip off. Not only that but you charged $250 just to come out and look at it. Terrible company! read more

Called these folks out. They seemed like nice people, but the moment the technician Chris arrived he started talking off by saying something along the lines of hope my drain pipe isn't in the slab. Then upon gazing at the unit he was relieved to see that was not the case and declared my coils were dirty and the unit was probably leaking coolant. (he hadn't even opened the system up.) So I was immediately concerned by this "HVAC whisperer" who seemed to know what the issue is without looking. As the visit continued he eventually told me it would be 600 to have the coils cleaned and 200+45/lbs to have the ac charged and it needed 2 lbs. Threw that guy out, and called a competitor. Ended up paying 75 to have the coils cleaned and the unit didn't need any Freon. Conclusions: Even the tech suspects a problem they should never make any claims until they've looked at the system. Hiller's prices are outrageous. There is really no excuse for lying about the unit needing Freon, that can't be overlooked. read more

awesome tech dustin c. july 6th in my opinion you should give military families discount especially being an american co. read more

I had done business with this company before and was very satisfied-- my option has drastically changed. PLEASE get multiple quotes before you sign with Happy Hiller. These guys were legit going to charge me 50% more than average for my needed work. The guys that came out were nice but - I don't think nice is worth 5k more than every other company on a brand new HVAC unit. Keep in mind the SEER and unit were the exact same. It's easy to get overwhelmed as a new homeowner but pause and research before you sign up for their service. read more

The tech showed up at a good time and was honest and nice. He gave me his advice and what he would do in my situation. He checked the unit and sold our problem. I was very satisfied with the service. read more

Called about a pretty significant plumbing problem that required a project manager for an estimate. An apparent miscommunication on the original phone call caused a tech to be sent out instead, who had to charge a service fee for his time (company policy). The tech was a super-nice guy, by the way (a Happy Hiller man ). I called their office and explained the situation and after reviewing all the info, they informed me that they'll issue a full refund for the service call. I ended up finding a local plumber who gave me a better estimate so I went with him instead, but even so, Hiller stood by their policy, "happy you'll be or the service is free." read more

I just called and they will have someone out to assist me this afternoon. The phone call was very polite and professional. So far so good!

Had a lot of work done by Hiller and I am a happy customer. My Ac was not cooling as well (not an emergency by any means) as it should and they came out on a Sunday to look at it. It was covered under my warranty so there was no cost for me. They filled up the coolant and told me that there might be a minor leak. We are members of the hiller club so they came out recently to do their annual inspection and maintenance work. Matt was very kind and was very considerate of my sleeping baby. I didn't even tell him; he heard her stirring in her bed and he whispered and moved around the house as quietly as he could. Bruce came and inspected the plumbing. He was friendly and went through the house with me and told me to watch for this and if that happens, do this. He told me to think about replacing the current plastic hoses for steel ones. We had our duct work cleaned today and Danny and Terry did a great job also. My child was settling down for a nap when they came and they waited to do her room last out of all the rooms so she could get some rest. Danny did a great job of explaining what he was doing. All workers showed up on the time. Someone always called ahead of them coming out to notify they would be at my home shortly. They all wore shoe booties to ensure my house stayed clean too. read more

Hiller's HVAC team was out to my house and installed my parts within minutes and the heat was on once again. We went through Hiller and they expedited my parts and had everything installed within 48 hours. Matt and his colleague were very knowledgeable and explained everything in detail. They took care of the problem and gave heat back to our home. As a Hiller Member I am starting to see the results of being a member though the cost was kind of high the warranty on the parts will be worth it. Job well done Hiller, thank you. read more

Hiller has outstanding customer service and very talented technicians. Stephen hunted down a complicated problem and fixed my heat pump on an emergency call this evening. I appreciated his efforts in keeping the costs down also. Overall great experience & I definitely recommend Hiller! read more

Got a $300 electric bill after seeing aux heat on the pad. Called Hiller they came out very quickly, charged us $90 to look at it. Charged us $200+ to "fix it". Kept saying aux heat so we had them come back out again they said they fixed something else. Aux heat is still showing and we just got another $300 bill. They are trying to charge us another $90 to come out and refuse to refund our money so we can actually get the issue fixed. We will not be using Hiller again for anything. And we will let everyone know how our experience has been. read more

If you need any refrigerant replaced in your heat pump Hiller will charge you 10 times what it cost. That's right, they have a 1000% markup on Freon. So if your unit has leaked out 6 lbs. of Freon like mine did you will pay $100 per lb X 6 = $600. On top of that they will charge a service charge. And to top it off, if you get the same technician I did he won't even attempt to check for where it is leaking claiming his detector is broke. They are the worst rip off you will ever encounter if you make the mistake of using them. read more

After being a Happy Hiller Club member for many years, now cancelled, I realized that their tune up visits was all about finding something, anything, wrong and then charging you excessive amount to fix. Their motto, Happy you will be, or the service is free" is a joke. I didn't rate them a 1, because when I did in the past, they had it taken down immediately. Plus I am unable to respond to their lying response. read more

I'm so disappointed. I called over a week ago. Had to wait do to being busy. Then they didn't show on the date they gave me so when I called the office about my air for the 2nd time they sent an electrical guy. He tried to help too. The person who makes appointments was supposed to call me right back. To date-nothing.utterly rediculous. I need an entire unit replaced but this company wont be touching it. read more
