Best Questions to Ask an Air Conditioning Contractor Contractor

Do you work with subcontractors?

The question is great for some industries and non-applicable for others. A general contractor, for example, will by definition employ subcontractors. Most Frederick 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.

How long have you been in Cooling business for/How long have been serving the Frederick area?

You'll always want to ask how long the company has been in business in Frederick. While this isn't a guarantee that the company will do good work, companies with longevity on their side must be doing something right. That being said, there are newer companies that do great work. If the company is under three years old, ask where the owner was employed before and for how long. If he/she has a long history of employment, it's reasonable to infer that he or she decided to go into business for themselves after so many years of experience.

Do you hire properly documented Cooling workers?

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.

Are you insured and/or bonded for Cooling?

You'll certainly want to ask them this. Steer clear of any company that is not insured in Maryland, because that means that any incidental damage they may do on your property will be a real hassle to recover compensation for. It is never wise to work with uninsured tradesmen of any kind. Most states also require that someone have insurance in order to be issued a trade license. If they say they're licensed but not insured, they're being less than truthful.
