Always Hire A Licensed HVAC Contractor

Why hire a licensed HVAC contractor?

Licensed HVAC contractors are required to obtain the necessary building and work permits from the local government office, depending on the type of work they are doing in your home. Most unlicensed contractors don’t bother with this paperwork. But many homeowners don’t realize that skipping an important permit means there will be a fine.

Licensed HVAC companies are also required to have some form of insurance to cover injuries to workers and damage to your home. Few unlicensed contractors have this kind of insurance. 

If an unlicensed contractor, or one of its employees, is injured while working on your HVAC system, as a homeowner you can be held legally responsible for the worker’s medical expenses, lost wages and the cost of pain and suffering. You will also have to pay for any damages to your home, or to the company equipment.

Sometimes your homeowner’s insurance won’t cover damages to your home that are performed by an unlicensed contractor – especially if you haven’t signed a written contract.

It can even be difficult to take an unlicensed contractor to court since they typically won’t sign a contract with you and it can be difficult to prove to a judge that any problems in your home were a result of the contractor’s work. Many are fly-by-night operators who disappear as soon as the work is done, making them tough to track down.

While a licensed contractor may seem more expensive, they can save you significant amounts of money in the long run, by filing the proper paperwork, having the right insurance coverage, and having the necessary knowledge and experience do safely install the best HVAC system for your home.


Now that you know all the proper steps to take to get your commercial HVAC license, there is no reason that you cannot go get qualified today and start taking large commercial jobs in the heating and air industry.
