How to Choose a Good HVAC Company

Your HVAC equipment is at the core of a complex system that contributes to your home’s ventilation and air quality. Choosing the right HVAC service provider assures you that your heating and cooling needs will be fully satisfied.

HVAC Contractor State Requirements

Every state has its own rules regarding licensing, insurance, bonding and continuing education of HVAC contractors. There are general requirements, however, such as contractors having a minimum of two years experience with HVAC systems, and passing a written test. With the rapid advancements in the world of technology, contractors may also have to take ongoing courses related to their trade as a requirement for keeping their license.

Your Needs

Before hiring an HVAC company, consider the brand and model of your equipment, along with its maintenance background. Also see which rooms in your home feel uncomfortable to you (too warm or too cold). This allows you to see clearly whether a prospective contractor knows enough about your system and can provide the solutions you need.


Ask for referrals and spend time calling these people, asking them what they think of the HVAC provider. After all, nothing’s better than first-hand information.


HVAC contractors with a license will have a state Construction Contractors Board number or something similar, and it must be found on their website. If not, don’t hesitate to ask them about it. When you have the number, contact the state board to know if their license is active. You should also ask the company to provide proof of their liability coverage. Don’t hesitate to ask for this information. Good HVAC contractors will gladly oblige.

Client References

Before you actually hire an HVAC company, ask them to provide three client references at least. Then call these people and ask them how satisfied they were with the contractor’s performance.
Also ask them if they will consider hiring the same company for a future need.

Written Estimates

If you need to replace your old HVAC system, expect the contractor to take measurements of your home, as well as inspect your ductwork, windows and insulation. Make sure the bid is itemized, includes details such as warranties, and presented in writing.


It’s good read reviews of your prospective contractor, if only to know its general reputation. However, it’s important to stick to independent consumer websites that feature authentic and credible reviews. Marketing websites are often full of fabricated reviews which can be highly misleading.


Finally, don’t just consider one prospective HVAC provider. Instead, consider at least two or three options so you can compare them and make a wiser choice in the end.
