This will be answered when you ask if all employees are licensed. The only way to obtain a legitimate tradesman's license is to be a legal or naturalized citizen of the US. The company may employ people in positions that don't require a license, however, so it's wise to inquire.

Many jobs in California will require municipal permits in order to be approved by the town's inspector. It's always good to ask who will be responsible for pulling those permits, and if you'll be expected to do it. You'll almost never be told to pull your own, but knowing that Corona Del Mar Cooling permits are required makes you appear to be a well informed customer.

The question is great for some industries and non-applicable for others. A general contractor, for example, will by definition employ subcontractors. Most Corona Del Mar Cooling companies do not, but there are exceptions. You should always ask this question to your service providers. If they do use subcontractors, ask if they're all licensed and insured independently.

Some companies may require a 10% deposit, some may not require any. For larger projects, you'll almost always need to give a deposit, and it's good to ask how much the deposit will be before going forward with a project. The Corona Del Mar contractor will know how much they need for a deposit when they've given you the estimate, so ask early.

Always ask for references, and always check them. Keep in mind though that the only references you'll get are people who the contractor is certain will give him a good review. You'd also be well advised to check online review sources in Corona Del Mar as well, which will give you a broader view of customer satisfaction for a given company.
