Customer service was great, labor is not ridiculous like other places and my furnace was fixed within a hour after arrival. Will be calling them in the further if needed and recommend to anything needing emergency assistance. The tech that came to my house was nice, respectful and showed me pictures and explained everything.

Owning a manufactured home makes repair & replacement for home maintenance a real challenge without the right resource. Our central air went out in early summer on our 20 year old home. We struggled all summer trialing used units until we found Capitol so reasonably priced we could afford NEW & warranted equipment & service. The guys were qualified, courteous & we're comfortable for the 1st time all summer!! So satisfied! Thanks Capitol!!
