Joe Welch did an excellent job replacing my water heater. He was very friendly, knowledgeable, and went the extra mile to help. He arrived on time, completed the work neatly, and left the area spotless.
John was an expert. We had a tight fit and what looked like a tricky installation, but John and apprentice Tariq did a first rate job.
John from Heil plumbing provided amazing service replacing my gas water heater. He answered all my questions and informed of everything I needed to know during the process. I highly recommend them for your plumbing needs.
The entire experience with Heil was easy and the staff throughout the process were courteous and helpful. Erik was patient in explaining everything before and after the job. He and his apprentice were efficient and clean and the workmanship looks top notch.
Seth and his apprentice did a great job replacing a water heater for us today. They were polite, answered all our questions, and did a very good clean up job. I really appreciate the attention to detail, and I would use Heil plumbing again.
Joe did a great job replacing the water heater. Highly recommended.
We call Heil for all our plumbing needs — and there have been a LOT in our new old home. Jake is always meticulous, reliable, knowledgeable, professional, courteous and friendly. We request him every time. Thanks for being a service provider we can trust our house to!
Erik and his partner were extremely professional and knowledgeable. Erik diagnosed the problem with my water heater and provided recommendations. I decided to replace the heater and they were swift with getting the equipment and installing.
Great experience! the technician, Eric Brown, was very thorough and answered all my questions throughout the process of getting my water heater replaced. He quoted me the best price out of all the companies I looked into. When he came to do the work, it was done very well! Thank you for all your hard work. I Highly recommend Heil Plumbing & HVAC.
Erik Young did an expert job at replacing our water heater. The job was done carefully and quickly, and he went through our options and answered all of our questions prior to purchase and install. Same-day service, and the new water heater has been working perfectly for the last few months. Highly recommend Erik and…
Great service provider with solid customer service and service.
Extremely professional and very prompt service. Others in my neighborhood use these guys. I will absolutely call them if I have further needs
Great guys! Explained everything clearly. Worked quickly and not pushy, cleaned up afterwards. Would use them again.
Eddie Heil and Heil Plumbing are incredible! I have used Heil plumbing for over 10 years on multiple jobs and they are responsive, experts at what they do, and always professional. I give Heil Plumbing my highest recommendation!
We are so appreciative of Jeff’s work and his professionalism. We will recommend Heil plumbing 100%
Robert and Chase did an excellent job. I needed a new water heater and wanted to change out my toilets. They explained the options and then installed everything that I asked for. They were very professional and cleaned everything up before they left.
High quality professional service
Very professional people. Did nice work. Did water heater evaluation.
We had a washer and dryer delivered at O'Dark30 and when they removed the old ones, we found that our water heater (purchased in 2002) was leaking. Sure enough, we called Heil for help and they were able to deliver and install a new water heater all before noon. They went the extra mile and connected up our new…
Quality service and a professional crew. The guys that installed our water heater were very helpful and supportive.
I wanted to have my water heater diagnosed due to some rusting water coming from the panels. Heil was able to send over a technician in 2 days. They even sent a text with the name and picture of the technician! Dave arrived on time and immediately started diagnosing the issue. He clearly explained to me what was…
Their price for an emergency replacement was much lower than a competitor! Excellent work, fast, we’ll done.
Brandon B. Of Heil Plumbing was absolutely phenomenal. He was extremely efficient and made sure that all of the previous work (done by a former homeowner) was redone properly during the installation. Heil gave me the best price they could on a new water heater, and their answering service/office staff was super…
Great work knowledgeable come in placed floor runners cleaned up after work was completed replaced water pressure valve and water heater in an reasonable time and brings system up to new county codes
I typically don’t write reviews, but we were so happy with the service we received that we wanted to make sure it was recognized. While on vacation out of town we learned from our house sitter there had been a gas leak to our home generator, and the fire department shut everything off until a licensed plumber could…
Jacob came out to do an estimate a week ago and I was very impressed with how thorough he was in both evaluating the setup and explaining to me what he needed to do. He was polite and easy to talk to. When he left I felt very confident in booking a water heater replacement. The replacement was also fantastic. He…
Great service …thank you!!!
Great experience using Heil Plumbing DMV. Mr. Marvin Chaney reinstalled my water heater that had been botched by another company. He explained what needed to be done, was pleasant, and cleaned up after the job. This company is my choice for all future plumbing.
Jacob took pride in his work. He answered all of my questions and made sure I was happy.
Marvin installed a new water heater for me. He answered all of my questions and provided excellent service from the project quote to cleanup. Very professional. So generous with his knowledge and advice. Will definitely use Heil Plumbing again!
I wasted several days calling plumbers listed in the Washington Consumers Checkbook who despite great reviews either did not answer phones, or were slow to respond to emails. Then I started a web search and found Heil. They had great on line reviews, answered the phone promptly, were quick to understand what I…
Excellent service in a timely manner. Very impressed with Jacob’s knowledge and demeanor. He was terrific!!
Marvin went above and beyond to get our water heater fixed, really appreciate it!
Fantastic. We woke up to a leaky water heater- they were there in a matter of a couple hours and had the unit replaced by the end of day. Professional, prompt, communicative, couldn't have asked for a better experience, especially under the stressful context.
Removed my outdated oil heat boiler and water tank; installed a new electric water heater. Marvin is a skilled tradesman and good guy. Easy to work with. Communicates everything clearly up front, delivered exactly what he said during the estimate on a job that few others would take. He has earned my business for the…
Prompt response, detailed discussion of the issue, clear quote and job details, and completion of the job on time. Plus recommendation of related non plumbing issues.
The entire Heil Plumbing DMV team were amazing and extremely professional. Following the scheduling of the hot water heater replacement, we received a call in less than 24 hours and got our water heater replaced a day later. Marvin was on time, very patient, knowledgable and professional. Our 20 year old hot water…
Appreciate the curteousness of my technician. He came in, did his job, and came and left within the estimated time-frames I was given. The estimate I was given was also very true to what I was charged. Very satisfied!
At last! A good plumbing experience after several bad ones in 1 month. Heil Plumbing DMV was just what I needed: reasonable cost, quick response to my need for a new water heater, a professional plumber who listened & responded to my specific needs, & he solved problems for me. I didn't feel pressured for…
It was wonderful working with Ryan O'Connell. He installed a water treatment system for acidic water in my house, repaired a poorly installed UV filter and added a proper sediment filter to protect the devices, he also did some preventative maintenance on some worn out parts on my well pressure tank tee. He then…
