Service tech Joe was friendly, knowledgeable, and took care of items that needed attention.
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…
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.
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,…

Josh was friendly and knowledgeable. No pressure at all / just factual. Would 100% recommend.
AC check up. Nelson was very nice
Howald always does a good job . He installed a furnace filter we needed and was very nice.
Yay
Showed up right on time, gave our system a thorough review and took the time to thoughtfully and clearly answer all our questions!
Anthony Alcaraz was great! Prompt, courteous and knowledgeable. We always recommend Howald!
Nelson came out this morning for my HVAC system maintenance. He was professional, kind, efficient, and knowledgeable. He took the time to check over the whole system and explain each checkpoint as he went. I signed up for the yearly maintenance contract for a single year but I will be extending that indefinitely, no…
Always a great experience. The technicians are always knowledgeable, friendly, and efficient.
Prompt. Helpful. Professional.
I will always use Howald until I'm worm food, and maybe even then to make my eternal resting place more comfortable.
Dan was very knowledgeable and helped me understand how to best use my AC system. I'll request his service for my winter checkup.
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…
Anthony Alcaraz did a great job today on our pro-active heat pump checkup. He's great. Highly recommend.
Josh always gets five stars!!
Very knowledgeable and efficient. I highly recommend Howald
Larry was great. Highly recommend Howald.
Frank tuned up my AC and cleaned the unit thoroughly. He did an excellent job and was very professional and neat. I feel confident that my AC is ready for summer now.
Technicians from Howalt are punctual, knowledgeable and efficient. I recommend Howalt highly.
Andrew Merrell definitely exceeded our expectations!! . He was very professional and courteous, and he was able to put in a new sink in the proper place and way, for the water. From that new sink, he put in a water line (and that he had to make two holes for the water lines). -ONE SIDE of One Wall from the sink,…
Wow. Just wow. We’ve worked with several service crews over the years in various home maintenance areas, and Howald has never, ever disappointed. They seem to be one of the last remaining honest professional groups out there. We had an annual maintenance for our AC unit today, and our almost 10-year unit looks brand…
David always does a great job. Highly recommend Howald Heating and A/C.
Knowledgeable, Efficient and very respectful! Took Care of everything in a timely fashion. Highly recommend! Serviced three air-conditioning units and changed all the furnace filters.
James Miller did a great job! He was thorough, informative, on time and efficient.
Anthony again provided excellent service. He opened the outside unit and tried to hose out all the debris. Most of it was too large to drain through the small holes so we used our grabber to take the debris out the top. He said he needed to get one for his truck. He is very professional and polite. We enjoy having…

Always have a good experience with Howald for the last 11 years. They're quick and efficient, and Greg Kessler, our most recent service person, was highly personable and knowledgeable. It's now a year later and we've had yet another good experience with their service person, Nelson Veirs. It pays to stay with the…

As usual Howald did a great maintenance call for the AC. They are always within the time range they give you when setting up the appointment and if not they will call you to let you know if they are running late.
Did a great job. PAUL CORSON
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.

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…
On time. Very knowledgeable and personable

He was actually early. He explained everything to me. I will request him again.
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…
Josh Thompson came out to perform our biannual service on the furnace. He does great work and is very knowledgeable. Howald has great people working for them and you won’t regret choosing them to be your heating, cooling, and plumbing service provider.
James was great will use again
We have had great service from Howald Heating and Air for many years. Senior Technican Josh is always professional and knowledgeable and takes great care of our system.
I have been a customer for over 10 years. Howald is the easiest and best contractor I have worked with since moving to Indiana.
Howald’s has been taking care of my furnace/air conditioner and plumbing for around 10 years. They are great and I love their work ethic and friendly professionalism!! Thanks everyone!!!

After receiving excellent emergency A/C service/repair from Howald some time ago, we signed up for their maintenance program. Today, the technician provided our annual service. Nelson was prompt, professional and extremely capable. He did a thorough inspection and left our home immaculate. I recommend Howald 100%!
Greg came right on time and did a super job with AC maintenance. Just as before, he was personable and polite, explained everything and took care of a problem I had with the furnace fan. He obviously knows what he is doing. It is reassuring to have a professional take care of things for me.
Luke was very pleasant, professional, and worked hard in the 90 degree heat! I’ve always been very pleased with Howald’s service and expertise.
Larry did a thorough service of our A/C units and explained areas where there could be future problems.
Josh, as always, was professional, knowledgeable, and pleasant!
Larry W. came in to troubleshoot a water issue in the crawlspace from the ducts. Turned out to be a clogged drain that he took care of quickly and efficiently. I really enjoyed my conversation with Larry and appreciate his hard work. As always, Howald does not disappoint - and they are reasonably priced. You can’t go wrong with Howald!
very nice and helpful.
Called Howald to get a second opinion on some AC repair work. Able to do the same work for one third of the price I had been previously quoted at. James was extremely helpful and thorough. Explained everything and did a full assessment of the work required. Would use them again!
Howald has replaced both my gas furnace and a/c systems and has done the annual maintenance on both for years. They are professional and responsive. 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…
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.
Professional, knowledgeable, answered my questions, personable.

Tomorrow I am having Howald Heating, A/C and Plumbing replace my equipment. I will write a second review following he installation.

Outstanding service - on time and very courteous.
The technician, Dan Power was knowledgeable, informative, and personable. The service he provided seemed very thorough.
The technicians come by the time scheduled and are respectful and courteous. Mike called to see if he could be a little early, which was fine, and then worked very quickly doing the spring maintenance on my A/C.
Regulat maintenance of A/C.
Great people, showed up on time, did awesome work, very friendly!
Now Howald has serviced me over time with a new AC, a new furnace, and a new toilet! I'm so grateful for your prompt, careful, polite and excellent-quality service! I live alone and don't always understand a problem or know what to do. You came out on a Saturday night when my furnace went out and got it going…
HOWALD HEATING & AIR is the best....everyone should use this company. I personally know these folks and they are honest and skilled...use them...or don't... at your own peril.
