When we had a problem with our AC we called Dayco, because it's the first name that came to mind and we had some acquaintences that worked there. We were told we would need to upgrade to a whole new system, that ours was not repairable- when in reality when we shopped around we just needed Freon. They were helpful about giving us information on budgeting our upgrade through the city which we didn't know about prior. They do have 24 hr. emergency service you need it.
