Furnace Icon

Furnace died on a Sunday. Temps below zero. Technician came out and did a temporary fix. Checked in later to see if it was still ok. Salesman out next morning and installers day after that. Explained everything thoroughly and gave me options. Respectful of my home and cleaned up afterwards. Very positive experience. Also replaced air conditioner. Note-also received senior discount

Great team with excellent customer service. We couldn’t be happier with our latest install. Fast and efficient from start to finish. I highly recommend the HVAC crew who came out for our install and Mike Collier, our rep, is a great guy and super knowledgeable. A+ start to finish!

I was qualified for the Focus on Energy credit to have a new furnace/heat pump system installed in my house for reduced cost. D&J walked me through the entire process, very professional from initial estimate to the install days. The team that installed also kept me informed of their progress. They were able to install the furnace, heat pump, and new ventilation in two days. I was very impressed. And, they left my basement cleaner than they found it! Great crew and polite all-around from the office, to the sales team, to the install team. Highly recommend them for any kind of heating/air conditioning projects!

I met Joe in Florida which I believe is president of the company. With small talk started, I explained to him that I have had boiler issues for 8 years and several companies come and look at my situation. Joe said call me when you’re back in Wisconsin, so I gave him a call and he sent Chad that does a lot of the boiler service. After a few hours Chad had figured out the entire system what needed to be done. So I indicated to move forward with what he recommended. Chad had replaced a lot of the parts that needed to be replaced and after 8 years of screwing around with other companies that had no idea what to do, Chad took care of the issue and now we have heat in all the rooms correctly and balanced. I would highly recommend this organization for anything relating to boiler work or other HVAC work that you might have to have fixed. In the past I had paid thousand and got nothing fixed. As a realtor, I will definitely send all my business and recommendations to Donovan Jorgensen.

I thought their pricing was extremely fair compared to what I paid in the past.

Thank you again Chad and Joe!!

This the eighteenth year we have used DJ for our heating and cooling needs. Yesterday they installed a new furnace, and as always the pricing was fair, the techs friendly and competent and the sale contact (Steve) was helpful and engaged. EVERY contact I have with anyone from DJ is outstanding. They hire, well, train well and build a great culture. I recommend them highly!! Scott
