Best Questions to Ask a HVAC Technician Contractor

Does the HVAC job require permits? If so, will you be pulling them yourself?

Many jobs in Illinois 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 Lake Bluff HVAC permits are required makes you appear to be a well informed customer.

How long have you been in HVAC business for/How long have been serving the Lake Bluff area?

You'll always want to ask how long the company has been in business in Lake Bluff. 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 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 Lake Bluff HVAC 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.

What guarantees and/or warranties can you give me? Are you a warranty agent for any brands?

These first two questions should only relate to services or good purchased directly from the service provider. Many products carry their own warranties, like roofing shingles or siding. It's useful to know what these warranties cover as well as how long they last. The "warranty agent" question is important, because often warranty agents work with the manufacturer to get you repairs under warranty at a much lower price.
