Purchased a new furnace this summer. They offered the same product as another company in the area but for a much better price on both product and installation. The installation was very well done -- quick, clean. The technician was great. Now that the cold weather is here, the furnace is living up to all the promises. It's keeping our house evenly heated, something our old furnace couldn't do, and it's very quiet. I like Glendale because there's no hype -- just honest, direct information and quality work and products.
