Just because a HVAC contractor is in demand doesn't mean they are the best choice for you. HVAC contractors will always enjoy a high demand, considering almost everyone has an HVAC system to maintain.
The Air Conditioning Contractors of America (ACCA) can help you find quality prospects. They have over 10,000 professionals and companies offering HVAC indoor environment field and energy services. Another option you have is checking consumer review and rating websites, where you can see whether a certain company or contractor is trustworthy and competent. Otherwise just ask people around you - relatives, friends, coworkers, etc. - for referrals.
If you want to look at an HVAC contractor's consumer ratings, go to the Better Business Bureau (BBB) and look them up. On the BB B website, you can check whether a company has been the subject of consumer complaints in the past.

Worker's Compensation Insurance.
It's required in case a worker gets hurt on the job.
Even the most reputable HVAC experts commit errors that can lead to accidental property damage. Liability insurance will make sure you are protected against the financial consequences.
A license and surety bond are the main requirements, but also need your contractor to have all the required permits to perform the job. If you're thinking of a new system installation, research which contractors are specialists in your specific brand or model.
Right from your first inquiry, you should have all correspondence with the contractor in writing. It's often best to send an email rather than calling the company. This allows you to keep a tab on what the contractor has said or promised. But don't depend on promises either. Make sure all quotes or bids are given to you in official writing. Ask for client references and talk to them. Finally, get quotes from at least three different contractors so you can make comparisons before deciding to hire someone.
