Having a good and trustworthy Heating, Ventilation, and Air Conditioning (HVAC) company is an important part of owning a home. Your home is supposed to be safe and comfortable, and making sure that your heating is operating correctly and efficiently is a key part of that comfort. However, finding a company to do this job can be daunting, so let this guide point you in the right direction.

1. Ask Friends for Recommendations

• Personal recommendations from friends are an excellent way to start building a list of potential HVAC companies.
• Friends can provide trusted opinions about which companies to consider or avoid, and you can ask follow-up questions about their experience.

2. Verify Active Home Improvement Contractor License

• Each state has its own rules for this.
• To find yours, Google "Home improvement contractor license" and then your state, and look for a web address that ends in .gov.
• The point of this license is to show that you are a reputable business and so it is easier for the state to track and take action against any attempted scam.
• In Massachusetts, the license lasts for two years before it must be renewed.

3. Look for In-House Installation Crews

• An in-house installation crew is a fancy way of saying that the company that sells you the heating or cooling unit is also the one installing and checking on the system.
• You don't want to be juggling several different companies to keep your unit in working condition.

4. Ensure In-House Electricians

• Similar to installation crews, having in-house electricians ensures coordinated service for your system's electrical components.
• All modern heating and cooling systems are advanced pieces of technology, so having experts all working together will result in better service and an easier time for you.

5. On the Mass Save Approved Contractors List

• Mass Save is a program created by the Inflation Reduction Act that helps improve the heating and cooling industry by offering rebates on environmentally friendly systems.
• In addition, they also created and tracked their own list of contractors who are experts in the HVAC industry.

6. Check Google Reviews and the Better Business Bureau

• While online reviews cannot always be trusted, they can still be very helpful.
• Look through all of the reviews and look for overlapping complaints or compliments and consider your own life.
• If you are forgetful or annoyed by phone calls then maybe avoid a company that has consistent complaints about customer service.
