Overview

Williams Comfort Products Made In America Since 1916!

For over 100 years, Williams has designed and manufactured quality heating, ventilation, and air conditioning products for both the home and business. It all started in 1916, when Jesse Williams began building gas steam radiators in Los Angeles under the banner Williams Radiator Company. Williams’ commitment to quality was clear from the start, and the company’s product line expanded over the next few decades to include gas-fired heating, gravity wall heating and counterflow furnaces. By 1954, Williams had expanded to a nationwide player, with a distribution and sales network that reached customers throughout the United States.

Williams reputation for quality products only increased, and in 1958 they were acquired by Continental Materials Corporation, an AMEX-listed company whose notoriety brought new levels of prestige to the firm, now called Williams Furnace Company. The company acquired Hydro-Aire/LANCO in 1986, a major manufacturer of fan coils and air handlers. As a result, Williams now offers more fan coil sizes and configurations than any other HVAC company in all of the United States. Finally, the product line was expanded in 1996 to include room console heaters.

Jesse Williams understood that his company had to adapt to grow, and so do we. Today, numerically controlled machinery is used to ensure both precision and quality. All Williams products are tested to the highest standards according to specifications set by the National Bureau of Standards. Engineering, R&D, testing and manufacturing take place at our factory in Colton, California.

Above all, we aim to treat the customer with respect and integrity to ensure that our customers come to expect the same quality from us that they will from our fine line of products.

  • 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.
