Robert L from Kirkland

Just had Richard out here to take a look with my furnace which was making quite a bit of noise. Had it apart, cleaned and resealed in 30 minutes. It's perfectly silent now, he also explained the situation to me in detail as he worked on it. Offered suggestions for the future of my furnace which I will heed. Awesome experience, I've used Cardinal for several years now and never once had the slightest issue with them.
