Very courteous gentlemen came to our house and cleaned the vents and ducts. We were told they had never seen ducts that bad. My husband said he was sorry that this was turning into a nightmare. One of the gentlemen said he liked having to work harder, some times the ducts didn’t need much cleaning. It did take some time, they were at the house for over 6 hours. Left us with clear instructions for the next few days. I would definitely recommend this company.

During the MN heat, my AC went out. I called Ahrens at 10:30 a.m. and I had someone at my house by 3pm. The service tech was very pleasant and highly knowledgeable. He had things up and running by 3:30. To me, that was spectacular service, especially when company is 40 miles from my house.

Amazing service! The team was prompt and thorough which is why we continue to call Ahren’s. Our AC went out during a week of 90 degree temps and Ahren’s came to service as soon as possible. They’re informative and are accommodating. 100% recommend!
