I had a great experience with Gene's appliance! They came to replace my hot water heater. The install was quick and it looks great (and works great, of course). Thanks again!

We have used Gene’s Heating & Cooling since we bought our first home 40 years ago!! ( both of our parents used Gens’s also) We use them for our Annual maintenance every spring and fall! Using this service we have rarely had a break down, additionally it added years to the life of our system! When it did come time to replace our system with a new high efficient system, we chose Gene’s once again! They have always delivered on the services they promised, for the price quoted!

We were in the process of selling my mom's house after she had passed away and the a/c quit working. I called Gene's the next morning and they came out that afternoon and it was a quick fix. So thankful they could get to us quickly and did a great job.

My parents did business with Gene’s Appliance. I feel honored to still be able to business with them. Furthermore, as an adult, to be able to do this business with Gene’s adult children makes me feel confident in *all* of our futures. (People: There really is something special about a family business that serves a community for this many years. Quality, price, and service will always the value.)

They’ve ALWAYS been incredible to us. They earned our business one Christmas Eve and we weren’t even existing customers. Our furnace went out, it was cold as all get out and they were here within an hour to get us up and going. They installed our new system for us. There’s no way we would have gone with anyone else. They were here within an hour this past Valentine’s Day. Record cold morning. Snow had blocked our intake pipe. Rick got us up and going. They are always, always, so very quick to respond to ANY call if it’s after hours or during regular business hours. This morning we had a power interruption giving us an error code on our screen. They rescued us over the phone…immediately! I couldn’t possibly recommend these folks more highly!!!
