I called this company when my furnace went out. Actually, I called the company whose sticker was on my furnace, and apparently Linksys had bought that business so the cal went to them. The long and short of it is that Linksys said they would install a new furnace for $ 3500, a cheaper version for $ 2500, or replace my existing furnace for $ 1500. I still have the written estimate. I was suspicious that they were trying to rip me off, and checked around further. I called Gary’s Furnace of Mountain View(650−967−8171), and Gary fixed my furnace(turns out I didn’t need a new one) for $ 365, including labor. Run, don’t walk, from Linksys. These guys are out to get your money. Call Gary instead.
