Recommended Customer Reviews

Thankful for Thorsen's! My $800 water heater began giving me problems within 2 weeks of purchase. A few months later and I was tired of getting error codes and coming home to a completely cold tank of water. I called the manufacturer (last Thursday) who called in service to Thorsen's. Jason came to my home (Tuesday) and was very friendly and worked with me to diagnose the problem(s) with the WH. He took over calling the manufacturer and explaining what was needed. The parts arrived this morning (Thursday) and within 4 minutes of receipt, Suzette from Thorsen's called to confirm receipt and schedule Jason's return. He was available to come immediately! Fifteen minutes later Jason was at my home and working on the unit. He quickly had the parts replaced and the unit fired up immediately without issue. Jason was professional, cordial and even friendly to my dog. I appreciated Thorsen's availability, friendly communication and expertise. I will confidently look to them with future needs. Thank you Jason, Suzette and the Thorsen's gang!

We love doing business with Thorsens! They set us up with the perfect ac/heating unit for our game room. It's perfect! This morning we had a plumbing issue and they took care of us again. Fast, professional and friendly. Doesn't get any better than that!

My family has been using Thorsen's for years. They're always professional and friendly. Their techs know their stuff and their prices are reasonable for what you get. They also have this buyback guarantee....You get to try the unit out for 365 days and if you don't like it, they'll buy it back. WHAT THE HECK!?! Who does that?! Just awesome!

I have had great service from Thorsen's. They are always timely, polite, and professional.

We used Thorsens years ago and they were great. Not anymore. Their customer service is terrible! I just got off the phone with a guy from Thorsens and he was condascending and sarcastic. His attitude throughout the whole conversation was that their screwup was my problem.
Our AC failed a couple days ago so yesterday morning I called to schedule an appointment and they told me it would be tonight between 7 and 8pm overtime. I was willing to pay the extra for an earlier appointment. Today I got home at 5 and found that Thorsens had left a message. I called back and someone picked up from their emergency hotline. As soon as I started asking about the call the person on the other line hung up on me. I called back and got a woman that said I shouldn't have received the call and that everything was fine and someone will be by at the scheduled time.
8pm rolls by and nobody shows up. I call back to see what happened and was told that they don't schedule calls after 4pm. I'm transferred to the sarcastic guy and he says since we never answered the phone when they called at 4 nobody would be coming out ""like normal"". He proceeds to argue with me about how I don't understand their protocol etc. I asked when someone could come out and he replies in an irritaded and sarcastic tone ""I have 6 calls tomorrow would you like me to make you my 7th?"" At this point I was done with talking and done with Thorsens... forever.
This experience was so bad it compelled me to make my first Yelp post.

All those that save me money get 5 stars for sure. Other companies recommended a 5K unit be trashed while Thorsen's cleaned it up and got it working right for a fraction of cost of replacement. Thank you Thorsen's for doing a great job!!

I've been using Thorsen's for about 20 years for plumbing repairs (old house, lots of problems!). They always are able to schedule me quickly, do good work and are professional. Highly recommended!

They are simply the best! I have used them for years!! We use them for our home and for my business at Planet Beach Contempo Spa in Turlock. They come out and clean out my dryer ducting at the shop every year. We do tons of towels at the shop and we have a ton of lint after they come clean our ducts the dryer works awesome! LOL! We use them for plumbing issues also! Great service at a great price! Thank you Thorsen's!

Grant from Thorsen's was able to get the air conditioning up and running when another company failed to after several visits. Thank you for keeping us from ""dying from the heat"" this summer.

3 trips and my water heater still isn't working. Seems they are trying to encourage me buy a new one. But the one I have is fairly new. Looking for a different repair guy now.
