Anthony was very professional and knowledgeable.
Punctual, professional and thorough. Kept me informed on what he was doing. Did an inspection and tune up on my boiler. Ready for the cold weather!
Prompt and reliable. Good communicator. Clearly stated what he was going to do and later recapped the results of his work.
The technician, Anthony, was very pleasant and thorough.
Great service! Mr. Powers always does a great job!
So appreciate their professionalism and attention to detail.
Daniel was very kind and courteous, he explained in detail the job that he performed today. Very professional young man.
Matt and Josh have been fantastic to work with! They helped to remove a radiator during construction and also serviced our boiler system. Josh was very thorough and detailed. I will continue to use Howald for our boiler system needs!
Very pleasant, competent man.
We use Larry Wright every time because of his friendly and excellent service! Still true as of Fall of 2026.
Joe was at our house 15 minutes after we smelled gas. He was very thorough in his work as well as his explanations to us. He fixed the problem to our satisfaction and, because of him, we feel safe in our home.
Excellent technician with up-to-date knowledge and skills!
Every time I have had problems with my furnace or air conditioner I call Howald. They do an excellent job! They explain what is wrong and always fix the problem. If you have an issue they come out that day and fix it. I definitely would recommend Howald Heating and Air Conditioning.
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 was great, explained some things about our whole-house humidifier I hadn’t known before. Really appreciate the care and time he took, was very thorough. I will be requesting him next time we schedule service.
Howald technicians are always professional. We’ve used them for about 8 years for a new HVAC and then semi-annual maintenance, which has been so helpful. Tonight, during one of those visits, a technician fixed a clog in the water line from the humidifier and it was no additional cost. It was important to us to get…
Educational, professional, and efficient service.
Been with this company for over 45 years.
Larry asked about and listened to my concerns. He gave me advice on how to best maintain my system. He is the BEST!
Joe conducted an annual furnace inspection and humidifier repair. He was very professional and personable. Joe explained his work and answered all of my questions thoroughly. I am very pleased with his work.
Daniel Core always does an excellent job. This is the 3rd time he has been here for different service calls. Today he came to service my furnace. While we were chatting I mentioned I need a new thermostat so he installed one while he was here. He is always polite, pleasant and clearly explains what he is doing. He…
Dan serviced my homes HVAC last year and was extremely courteous and professional. He appeared very knowledgeable and was able to explain things in a clear manner that a non-skilled person can understand. I specifically requested him again this year. I had to incur a bit of a wait but it was well worth it. Once…

Very nice and knowledgeable service technician.
Sam was efficient and explained the work performed and his recommendations.
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.
I’ve used Howald HVAC and plumbing for 50+ years and they have been great.
Dan is excellent. Knowledgeable, courteous, timely. Definitely my go-to. Howald is the best!

Daniel did a great job!
Our malfunction was hard to figure out. James clearly knew his stuff and dug deep to try to find a simple and inexpensive solution. In the end though we’ll have to spend some money on a motor replacement. But we can do that confident that had it been something simple, James would have found it. We do not worry that…
Dan did a wonderful job. He is professional and very efficient in his work.
Noticed dampness around the base of the furnace and called Howald. Tech was able to get here in a couple of hours and took care of the problem. Always satisfied with Howald’s service.
Larry White, technician, checked the AC for the summer. Explained about a device that would prolong the life of the AC compressor. Professional, knowledgeable and honest.
