    Unbelievable Customer Service

    Posted by Thomas Komoroski Jr on Jan 24th 2017

    I ordered this kit late Friday afternoon and When the mail arrived on Monday It was there. I didn't pay to have it shipped over night either. This company has gone out of it's way to answer any question I had about this upgrade kit. It installed fast and easily. The only trouble I had was with the green ground wires. The instructions are vague. I improvised and now this old P38 is running better than ever! Thank You Mountain View Hearth Products!

    Best price fast shipping

    Posted by Kenneth Larry on Oct 5th 2016

    I purchased this product off of this site due to the low price + free shipping. Ordered it on a Friday and it was on the door step Monday, also it was packed very securely (bubble wrap, packing peanuts, etc). It came with everything it says and everything worked, though the install instructions can be a bit vague. Over all I'm glad I upgraded and I'm happy with the product, I would definitely recommend it.

    NO Returns

    Posted by anonymous on Aug 29th 2013

    I think the no return policy is a gamble. No I have not ordered this product, so my review is not against this upgrade board. I have built computers and have received a bad board from time to time. Static electricity can damage the board before it arrives to the destination, or perhaps a board passed quality control, which was really bad. These boards have about 35.00 worth of material, and the markup prices are out of this world.
    Company response: The no return policy is in place to protect us and our customers from damage to a control board while in a customers possession. As you noted yourself something as small as static electricity can damage the boards. That is why these boards ship out in an anti-static bag. If you received a board and it was bad due to either shipping damage or failed quality control, then it would be covered by either the part warranty or by shipping insurance we put on our shipments making the risk to our customers extremely minimal. The price we sell our parts at is generally MSRP and is determined by the stove manufacturer with Harman control boards almost always being the least expensive control board of any brand we carry. -Sean Harmon, Office Manager.
