Recommended Customer Reviews

I just want to thank Nick for all his help. I had sewer backup into my yard. He got everything fixed up fast. He was friendly. He made sure everything worked and even got everything sprayed down and cleaned up before he left. I highly recommend!

Our AC stopped running, (no cold air). Jarrett came out with a great attitude and informative answers to all of our questions. He is a valuable asset to the company and we'll ask for him by name if ever we call again!

UPDATE
I did receive a call back towards the end of the business day the following Wednesday from the office staff regardingy my initial inquiry into the labor fee. They had just completed their investigation and wanted us to know they would only be charging us for 1 of the trips and not both ways as originally calculated. The net result was a check in the mail for approximately $50 meaning we were now being billed for 1 hour 15 minutes rather than the previous 1 hour and 45 minutes on a 1 hour job (53 minutes). I'm still not completely satisfied given the misrepresentation of fees during the initial call and will keep this experience in mind, both good and bad, for future HVAC needs.

We had worked with this company for years. Unfortunately, their customer service and work has declined. We finally found a company that stands by their work.

DO NOT USE THIS COMPANY. They are a freaking joke.
Our Carrier Cor thermostats upstairs and downstairs gave out a month ago and we had to call these people because they're supposed to be specialists at fixing these newer systems. Not!
They sent one guy out who said that the control board was messed up so they had to order a new one but meanwhile he would just hook up the upstairs thermostat until another tech comes out to install it. The new guy comes out a week later and says that there were wire problems???? We tried to contact his boss but I am sure they knew they fucked up so nobody called me back because they werent trying to own up to their faults. the guy ended up installing some cheap thermostat downstairs for us and said that we'd have to call and have another person come out to fix the wire problem. Wtf?
In the end, nothing was fixed!!!! so how are they gonna try and collect when the job wasnt even done at all??!???
they are literally a waste of money!!!! I found someone who is much more reliable and knowledgeable!!! Screw these people!

I've been a Thorsen's customer for years, even before I was a home owner. I called to schedule and was told the maintenance is not 67.00 that it would be 75.00. Ok. Then because they weren't going to have anyone in Denair area (5 miles from business) on Friday they would have to charge me mileage fee.
You may want to rethink using Thorsen/Norquist as being a customer for 20 plus yrs and another 10 yrs from apartment management doesn't seem to matter. Only the upcharges. Thorsens use to be great!
By the way, I wasn't having an issue just doing a maintenance of AC unit. Any ideas who is in customer care and servicing business?

We've relied on Norquist (now Thorsens-Norquist) on and off for years. We do the biannual servicing for our air conditioner and heating units. Technicians are friendly and professional. Price is reasonable. They are quick and efficient and keep our old units working nicely. Thank you!

Thank You Gabe Miranda and crew.....knowledge and professionalism!......got us out of a big bind......fixing other service peoples mistakes......stayed on it until the issues were resolved!!!!

Very expensive. They will only make an estimate and when job is completed they will not give you a breakdown of parts and labor. Bill was exactly the estimate.

I was in a bind on a very hot day. I called around for prices and availability. Bottom line Thorsen's came out and got the job done for a great price. The service technician was extremely helpful and explained everything he was doing. Within a hour my AC was humming right along. I would recommend them and will call again if needed.
