Choosing an HVAC contractor can sometimes seem like a daunting task, and even more so if your cooling or heating system has gone out and you need a fix immediately! Stash this list away for a rainy day, or even better, establish a relationship with an HVAC company now when you don’t have a problem so there is no question who to call when you need service! These questions to ask your HVAC contractor will help you find the right company for you!

Are you licensed?

If you are dealing with an un-licensed HVAC contractor, you are asking for trouble. Your legal options are more limited if something goes wrong. Also, most homeowner insurance policies will not cover damage from work done by un-licensed professionals. Most importantly, you will not receive the best work. Licensing requires continuing education to keep up with the most current technology and service techniques. You want someone with that extra knowledge working on your HVAC system.

Are you insured? Can you show me the certificates?

Will your HVAC contractor guarantee satisfaction?

Reputable and trustworthy contractors will carry workers compensation and general liability insurance. This protects the contractor and their employees, but it also protects you. If property is damaged or someone is injured on the job at your property, you do not want to foot the bill. Proof of insurance is not an unreasonable request from any kind of contractors working on your property.

How long have you been doing business under the same name?

If a particular HVAC contractor has a bad reputation, it is a common tactic to start a new company with a new name to avoid detection. Therefore, look for a company who has operated under the same name for more than five years. If they have still maintained a great reputation , you will have more reassurance in their stability and true work ethic.

Do you provide a warranty for your labor? How long?

Providing a good warranty for labor shows that a contractor stands behind his or her work, and that of their employees. A 30-day warranty on labor does not show pride in the work that a contractor performs. A one-year warranty shows that a contractor strives for the best work and stands behind it.

In conclusion, assuring the professionalism and expertise of an HVAC contractor is essential in protecting your home investment. By asking a prospective HVAC contractor these questions, you will know whether it is the right contractor to work in your home or business.
