These guys were the highest estimate of 3, but went with them cuz of their 24 hour service and decent referral from a friend. Get new furnace. 1 month after warranty, water pump breaks. Floods furnace room. Dylan comes. Says "ya, those pumps are not very good. Installs a new, better one. Says no charge. Gives bill stating that. Then i find out I AM BILLED! So, why does J&S install crappy pumps? What else will break down on my furnace? Will let all my clients and family/friends know. A disgrace.
