I've used Accredited many times over the years.
They come on time and are always knowledgeable about the service needed (most recently they came to try to fix my ancient dryer).
Sadly after the parts were ordered and installed it became clear my dryer was past the point where it was repairable. I just needed to buy a new dryer.
They stood by their warranty and came through with a full refund despite making 3 attempts to fix it.
Great reputable service company.
