Fan motor went out on a very warm day. Larry Wright went above and beyond to get it fixed on a Saturday.
Always a great experience. The technicians are always knowledgeable, friendly, and efficient.
Dan was very knowledgeable and helped me understand how to best use my AC system. I'll request his service for my winter checkup.
Josh was prompt, friendly and professional. He explained what he was doing. We have used Howald for years and appreciate the professionalism and helpfulness of all their employees.
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.

Daniel Core was very professional and thoroughly explained everything he was doing and what it would cost. He also always made sure not to track anything into the house from the garage. Daniel just as good again as a above!
My wife said David did a wonderful job...A++

We enjoy having…
We've been customers for 10 years now, and every single tech we've worked with has been so great to work with. Nice, professional, and knowledgeable.
Josh arrived when expected, was respectful of the property and completed the tasks efficiently. Josh answered all my questions, gave me good advice on my unit. I felt confident in Josh's ability and skills!
Nelson was extremely personable and did a very thorough job! I’d be pleased to have as our technician again.
Excellent service. He spent at least 2 hrs servicing and cleaning air conditioner. Lots of cottonwood!!!!
Dan was excellent, very quick and efficient.
We continue to be happy with the service provided by Howald, in good part because we know the technician, Daniel, well by now as he has consistently been our provider for the past 5 visits. He is professional as well as pleasant and takes time to explain all that he is doing and why.
Brandon Whitehead was great. Thanks.
So professional, prompt, helpful, reasonably priced. Great communication. Thank you!
A/C tune up was performed by Nelson. On time, checked everything, cleaned the units and replaced a failing part before it broke for good under warranty.
Mike was thorough and gave us suggestions for extend the life of our equipment. As usual we received great service.
I’ve used Howald HVAC and plumbing for 50+ years and they have been great.
Great service!!
