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.
