John was very professional and courteous.
Andrew did a great job fixing a leaky toilet the same day I called.
I had my problem diagnosed and today was the day they replaced the plumbing under my sink. They were on time, friendly and efficient. I’m very pleased with the work that was done. I would definitely use them again and I thought the price was extremely reasonable.
Brandon W was very thorough, sought out the problem, and then replaced the outside spigot at our request. A year ago Brandon replaced our water heater that was leaking and replaced a poorly installed bladder done by another company. He has also replaced bathroom faucets and drains for us. He’s a great guy and does a…
Big job this week with replacing some old cast-iron pipe with PVC in a second floor drainage system down to the basement. They did a great job Cleanne efficient got done before their estimated time and then came back and serviced our hot water heater. Andrew was on both jobs and is always pleasant, polite,…
Great neighborhood firm. Prompt, professional service.
Another great job by Howald. John arrived in a timely manner, assessed the plumbing problem, and made prompt repairs, all for a reasonable price. I don’t call anyone but Howald because I know it will be a superior experience. Thank you!
John is a great person to have working on your plumbing issues - he explains everything clearly and is very friendly.
Fast. Professional. Price always reasonable.
Sam did a very professional job! We were pleased with the quick service from Howald and plan on using them more in the future!
I will always use Howald until I'm worm food, and maybe even then to make my eternal resting place more comfortable.
Outstanding as always
Sam showed up on time, was extremely knowledgeable, courteous and professional. Concluded work in a timely manner, and the result was better than expected.
The tech was friendly, professional, courteous, and and answered all of our questions. The work looks quality and he even gave us pointers on how to prevent additional issues in the future - five stars
Howald to the rescue once again! They got a plumber out within a few hours of calling to fix a water leak. As always, they're were beyond prompt and professional.
Update to my previous review: January 2026: Still very pleased with the excellent service provided by Howald. Today they fixed our leaky kitchen faucet & replaced our old water filtration system with a new one we had bought elsewhere. The technician was on time & worked hard to finish the job efficiently. Highly…
Howald always does an excellent job at a fair price. The plumber, John, was professional, knowledgeable, and fixed our issues in good time without rush or delay.
Knowledgeable and experienced
I was without heat and the same day service was very much appreciated. The service was exceptional starting with the call. The woman I spoke with was courteous and professional. She too, needs kudos as that first impression is so important! Dan Powers was courteous, respected my home and thorough. He was pleasant,…
Andrew came out to do some plumbing and was amazing to work with! Their quote was less than other plumbers. They are privately family owned (not owned by private equity) and have done a few jobs for us in the last 5 years. They’ve always done the job well and I’ve never needed someone to come back out and fix their work.
I am quite pleased with the service from Holwald HVAC. They have taken care of my home and business for the over 30 years. They have installed, repaired and maintained my HVAC system for my home and company. My furnace stopped working at my house on New Years Eve. I wrote about my misfortune of the internet. I…
Sam on the plumbing team is always amazing! We have an older home and he manages to find a solution to any problem! Highly recommend!
Great to see a family owned / managed business as an alternative to larger and more unresponsive companies. Sam was superb - great service and a pleasure to have in our home.
Professional, knowledgeable, and friendly too. Love these guys!!!!
Professional, timely and service with a smile. Fair pricing and quality service. Thank you Brandon.
Another great job, and timely also
Sam is a pleasure to work with. His attention to detail and the pursuit of the right solution for the job at hand while considering the constraints of cost, capability, and fit, are outstanding.
All-around excellent service. Next day service was scheduled when I called. Plumber arrived on time. A complicated problem was fixed efficiently and effectively. Arman was pleasant, knowledgeable and clever. The checking out and payment process was by tablet and quite simple to use. I will certainly call Howald next…
Ricky is so helpful. He has come to our home multiple times and is always timely, professional, and knowledgeable in his solutions.
I heard some drips but couldn’t tell where they were coming from. Howald sent John out in less than 2 hours. Detecting the origin of the leak was not an easy job! John worked on it and called for backup from 2 additional plumbers—all were excellent! They were pleasant and diligent and finished the job in one day!…
We love our Howald team! Dan F keeps our old crummy furnace working. (Unfortunately, it was installed during the Howald Hiatus). That short time without the Howald group really made us appreciate the great work they do. So glad they returned to our community. I hope we never have to call another heating and plumbing…
Always the best service for HVAC and Plumbing !! Andrew, Steve, Arman, John, and Sam are leaders in “Plumbing” = GOATs !!!!!!
Another satisfied customer!
Always on time, courteous and explain if problems. Pleasure to do business with. Larry is always pleasant and helpful.
Always excellent. Have used them in many homes for years. Nelson was great today. Very thorough in his trouble shooting
Always excellent!! Larry and Joe were on at the house after hours within minutes. Fast and accurate repair w fair price
My water heater is in a walk-in attic with a slanted ceiling. We needed to replace the existing water heater and decided because of the close quarters we would replace it with a tankless water heater. It took all day because of plumbing and wiring changes required. They worked diligently and continuously and it is…
Knowledgable and delightful.
Replaced a faulty PRV. Solved issue created by a prior plumber. Explained work needed and why and explained features of new PRV. Would recommend.
Good service and a very thorough explanation of the work that needed to be done and why which was very helpful. Took the time to answer all of our questions.
