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…

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!
Regular check up
See above
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.

Every technician that has ever come to the house has been courteous and knowledgeable. Most recently Dan took the time to walk me through the maintenance he was doing…
Larry was excellent at diagnosing the problem, explaining the problem to me, and suggesting a recommendation. He is also very professional and prompt.
Dan F. has been coming to my house for several years (at my request) for my spring and fall tune-ups. As always, he did a very thorough job today with my A/C and even cleaned the sides of the unit which were very dirty.
Really like James M. their technician. He’s been twice to my place & always explains things at a level I’m able to understand, while not being pushy or feel like he’s trying to upse me on things I don’t need.
Great experience. Dan was exceptional. Thank you so much!!!!!
We have needed Howald for 3 separate jobs and I've been impressed each time with workers, their knowledge base, and efficiency. All job estimates have also been accurate.
James MIller was very good, and we would be glad to have him again. He took all the time necessary to answer our questions and explain what he was doing. He was also friendly and approachable.
On time, professional, excellent quality at a reasonable price.
They came out immediately and got me back up and running
Frank is always a pleasure to work with. He has serviced our units for years and has caught issues early to keep them from becoming problems.
I have only 38 years of experience with the company, but this is my opinion. Larry Howard and company are dedicated to providing superior service . The technicians are qualified professionals who have been in the business for years and like what they do. Not a chain or conglomerate focusing on revenue, but a small,…
They were very professional and polite and knowledgeable
Incredible service as always - Frank is an A+ professional- got everything serviced and the humidifier’s running again
Nice guy, on time and efficient. Thank you!
Arman did a very good job installing a new sink and faucet, as I knew he would because I trust Howald to always deliver fine services. It's so comforting to know I can call on Howald and their skilled professionals to complete a project to my satisfaction.
Very professional and friendly service.
Josh got everything fixed quickly! Thanks!
I am very pleased with the service. David was very professional and courteous, explained everything. I highly recommend Howald Heating.

Maintenance was completed satisfactorily...Larry was thorough and took the time to answer all our questions! Thank You!
We have used Howald for many years and they have always delivered great service with professional, courteous and knowledgeable people. Frank Kanz who performed our most recent service continued that excellence. Frank arrived on time, introduced himself and outlined the work he would perform. He was knowledgable and…
We have used Howald since they started. We were Broadripple Heating and Air customers when the Howard’s owned that. Customer service, professionalism and willingness to be creative in addressing and solving problems are why we continue to do work with them.
Tech James was very informative and thorough in his service. I will request him in all future services.
Nelson was prompt, professional, and pleasant. He did the yearly maintenance on my A/C, answered my questions, and renewed my service agreement. He was neat and thorough. I have used Howald Heating for many years and have always been happy with their company.
I love Dan! I have been using him for several years and he is professional, nice, and trustworthy!
Greg was very skillful and conscientious. Enjoyed our discourse. Not a calm person; super high energy (and that can be a good thing!).
Great service from Howald, as usual. Can't stress that enough: AS USUAL. Dan Flickinger was our tech for the last visit. Thorough, knowledgeable, professional.
Larry is great. He's pleasant and helpful. He clearly knows what he is doing. Thanks!

First time I've used Howald. Josh was great, checked out my boiler and gave me suggestions for maintenance plan. On time, and nice guy.
Very good service. Switched to them in 2018 and have been very happy.
James the boiler man got right to the heart of the problem and fixed my 18 year old gas boiler system for $106, and showed me how to take care of it myself if it should break again in the future. I gave them my HVAC maintenance business going forward. Two other "corporate" outfits had previously quoted exorbitant…

My second stage heat wouldn’t come on! I’m am so glad Dan found this before it was needed! He also fixed a small problem I have had for years. Thank You!! Howald is the best!!!
Josh Thompson was courteous, safe and tenacious. This was a very good experience.
Cannot speak more highly of Kevin who came out to do the maintenance check on our AC and furnace. We bought our house a year ago and noticed some issues with the cooling and heating being off. He came in, was very friendly, not only checked the AC and furnace (and identified issues and fixed them quickly), but also…
