Aardgasservice Noord B.V.

Gave a terrific arrival time within a period of 4 hours in the afternoon, and still decided to come 30 minutes late. Worker said nothing during the whole "checkup", and sneezed two times on my floor which is very nice.

The representative came to my home. He has promised everything to come up with a plan for a new heating system. Heard nothing more. Called after a month and was told they would call me back that same day. It has now been 3 months and we have never heard from this company again. And they don't answer the phone anymore now that they recognize my number. Stay away from this company because they will never be heard from again. Luckily I hadn't invested any money yet.

Heat pump purchase, installation and aftercare went perfectly. Agreements were kept and even proactive contact was made after commissioning about comfort and operation.

I had a great experience with this company. I had a solar panel system installed last April, which was neatly delivered and finished, with good explanations and very skilled, experienced technicians. There was a small initial setback due to the meter box, but the technician quickly resolved it. Last Friday, the correct inverter/3-phase meter connection was completed. Another great experience. I highly recommend this company.

Wow, wow, wow. I was a customer of another company for years and this year I had an ASN technician visit for the first time. What a world of difference. This technician did not first have coffee, but immediately went to work. I believe my boiler has really had a good overhaul for the first time in years. The lady who scheduled the appointment also did her best, since I never open my email. She kept calling until she got a hold of me. IASN is truly a company where they sincerely do their best for the customer. What a relief! Highly recommended!
