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…
I’ve used Howald HVAC and plumbing for 50+ years and they have been great.
Technician was prompt. The work was done to perfection and my basement was clean when job was completed. Larry hires the best people. That’s why I have been a loyal customer for years. Thank you very much.
We are very pleased with the service we always receive from Howald and from Larry Wright and Mike Patterson! They are a trusted resource for our family! Thank you very much!!
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.

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…

Our salesperson, Don, went above and beyond to help us replace these units quickly and within a budget we could afford. Installation is always on time and professional. Can’t thank this company enough for their help.
Howald installed a completely new system: heat pump, air handler and thermostat. The installation was problematic as the existing wire between the A.H. and heat pump was causing connection problems. They found a frayed wire, confirmed everything was working and left. 2 days later the system was heating & cooling…
