Customer Reviews
Janine Loyd
We got great service from Will, the owner. He listened to what we need and our budget concerns and responded with options that suit our situation. No up-sell, no nonsense.
Douglas Booth
We have been using JW Hanson for nearly ten years. One of the first projects was to address problems with a new furnace installed by another contractor. Hanson made the fix seem simple. Since then they have converted all our HVAC and hot water systems to heat pumps, installed an emergency backup generator and performed on going service on all these systems. Now they are installing a leak detection system. Will and his team are the best and always my first choice.
Meg Hurt
Nicest and most efficient young man I have ever had work on my furnace or air conditioner or any other appliance. The company office staff is very sweet. I highly recommend this company Hanson. I quit with another company (Moore) I had been with for 15 years because their timeframe was totally unreliable, phone calls were not returned, they changed who I had an appointment with for their convenience, they changed the date and on and on and on I definitely will go with Hanson and will recommend them to my friends.
Rich Vitali
Will and his team are the best. I have used JW Hanson for our rental property and our main home. Will designed our new system for our home rebuild after our original home burned down in a wild fire. He always listen carefully to our concerns and comes up with great solutions. All their employees are highly professional and friendly. I highly recommend JW Hanson. You can trust them to get the job done right and to treat you fairly.
