Researched and ordered my fireplace from US FIreplace Store. Pricing was a fair value however, the customer service was EXCELLENT! I had an issue with the direct vent venting. I called US Fireplace and the correct items were sent out the next day AND Janessa stayed on top of my return authorization and sent me the permissions and documents I needed to return the incorrect item and no cost to me, including return shipping. Overall, I am a very satisfied customer and my fireplace looks and operates flawlessly. I am glad that I selected US FIreplace to source my direct vent fireplace. Thank you for the great service.

I had placed an order, through Lowe's Home Improvement, for an Electric Firebox: Revillusion RBF42. Ordered 1st part of January. Was told I would have it in 3 weeks. When checking to see is it came in, was told it was delayed to 3/15. Was then told is was delayed until 4/25. Waited until 4/27 to check on it. Was then told it was now delayed until August. This firebox was going in a new Sun Room addition. I could not get my final inspection until the Firebox was installed. I went on line and googled for this same product. US Fireplace Store web site was given to me. This was on a Saturday. I call and reached a very nice man. Explain what I was look for. He checked and told me they had 30 of them in stock. I almost fell out of my chair. I clarified with him the product I was wanting. I ask how soon could I get it. He told me it would ship today. Again, was amazed. It arrived on the following Monday. What a pleasure and a relief working with US Fireplace Store and their employees. Exceed my expectations.

Great prices, quick delivery and fast hassle free services on the issue I encountered. I had purchased an electric fireplace unit that would not fit into the existing fireplace space. With one email I was able to get the wrong fireplace refunded and picked up at my home at no extra cost and the new one I purchased and delivered free of charge. Great company.
