This is a work in progress
Always top notch service. Mike, our technician, is terrific. And the rest of the staff is also excellent. Larry came out today and was excellent.
Josh was very professional and discussed the problem and suggested solutions. Polite, courteous and quick to respond to the problem.
My AC went out on the hottest of Aug days… Howald was able to squeeze me in the very next morning. Nelson was thorough and explained everything clearly.. and he even had to get up into a very tight small attic access with no complaints. We’ll definitely be looking into their services for our future needs.
Josh was friendly and knowledgeable. No pressure at all / just factual. Would 100% recommend.
Larry was knowledgeable and very thorough as he performed annual service on our A/C.
Luke was great! Had a blown furnace fuse and he diagnosed and fixed it very quickly. Nice and personable service.
Always a great experience. The technicians are always knowledgeable, friendly, and efficient.
I called for service and was very satisfied with the results. I ended up with a solution and a fix immediately. It was appreciated on a weekend when the air conditioning was not working. Having a service plan really helps!
David was great! He came out on a Sunday to get my AC running again. Good communication, figured out the problem and took care of it!
Dan Powers with Howald did a fantastic job! We were initially quoted $10-11k for the work that One-Hour Heating & AC reccomended, but Dan was able to get everything fixed within in an hour for about $550 instead. The office staff were super helpful and were able to get us scheduled quickly - oh and btw, no AI, all…
Great customer service. Dan our service technician was great! Very friendly and helpful. Explained everything
Great and timely service work.
Always do a great job
So impressed with how quickly they came out and they were able to repair the problem on the spot.
Prompt; efficient; explained problem and provided a solution.
Air conditioner was not cooling.Dan arrived very friendly and looked at furnace and thermostat and went to ac. Explained what he was looking for, and ran test. Showed me the problem quote a price . Installed new item and checked rest of ac. He was very professional and friendly. Would recommend to my friends and in family.
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…
David did a good job with the repair. Very professional service.
Things always go smoothly and there is good communication in advance, during and after the job.
Josh is the HVAC champ; does careful, detailed work, explains options well. Really happy he was able to adjust his schedule to come before COB.
Howald came out to fix a non-working, 6 year old AC unit at our house. They got everything working, and then a couple days later, a different component unrelated to the first repair, failed. They came back out in the same week (the day after I called to report the issue) and fixed it at no charge. Dan and Dave were…
Dan did a fantastic job. Got everything diagnosed and repaired quickly. Appreciate his professionalism and attention to detail.
Competent and fairly priced.
This review is long overdue, meant to send it a while back. My AC had stopped working one night during a heat spell we had and I’m kind of new to this city so I wasn’t sure who to call. Some neighbors on NextDoor recommended Howald Heating and A/C, so I gave them a call after being told by Peterman Bros that the…
Professional. Knew his craft!
Sam Byrd was very knowledgeable. They only fixed the issue but made it better
Larry was great!!!
I’ve used Howald HVAC and plumbing for 50+ years and they have been great.
David was wonderful during both visits. Very professional and attentive.
Fast service. Dan was fantastic! They had my AC up and running that day! Thank you!
Josh was great, he was on time and answered all questions. Very easy to work with.
Dan is excellent. Knowledgeable, courteous, timely. Definitely my go-to. Howald is the best!
I love Howald. They do a professional job and take good care of their customers.
We have had Howald as our provider for all of our HVAC needs since shortly after moving into the area 6 years ago. We did try another place first, but were not satisfied. I find them to be dependable, responsible, efficient, and fairly priced. The tech is always conscientious and explains everything, answering…
Frank was efficient, conscientious and easy to work with. Howald is the only company I’ll use for HVAC. Just had them repair a broken pipe in my heating system, a delicate repair, and they did an excellent job, as always. Good to have a company I can trust!
We are very pleased with the service we always receive from Howald and from Larry Wright and Mike Patterson! They are a trusted resource for our family! Thank you very much!!
I cannot use enough superlatives to describe Josh - suffice is to say he is my hero!
Ive used Howald for 10 years. They have always provided professional quality service. I depend on them to make sure my home is comfortable and well maintained so I have peace of mind about the things I don’t understand. They’ve made sure I have top quality products that are well maintained and last. Their staff have…
Dan was fantastic and the entire Howald team was so helpful in the process. Highly Recommend!
