Some states want contractors to pass tests or have work experience. Others need them to finish an apprenticeship or get special bonds. Some places only need local licenses, not state ones. Here’s a simple table to show what you might find:

License Levels | States may have different license levels like journeyman or master (like in Maryland, Florida, Virginia). |
Local vs State Licensing | Some states only need local licenses, not state ones (like Illinois, Indiana, Kansas, Missouri). |

EPA Certification | All contractors must pass a test for refrigerant handling (EPA Section 608 certification). |

Commercial Auto Insurance
Umbrella Insurance
Equipment Insurance
Commercial Property Insurance
Cyber Liability Insurance
If a contractor has these insurances, it shows they care about safety and their business.

Home Evaluation
A good hvac repair contractor will always check your home before giving advice. This step is important if you want to know how to choose a heating and air conditioning contractor. During a home evaluation, a technician looks at your heating, cooling, and ventilation systems. They check for wear, leaks, blockages, and things that make your system work less well. They also clean and tune your system so it works better.
Here is what happens during a professional home evaluation:
The technician checks your furnace, heat pump, air conditioner, and other equipment for damage or wear.
They look at your ductwork for leaks, blockages, or insulation problems.
They test indoor air quality by checking filters, humidity, and ventilation.
You get a report with ideas for repairs or upgrades.
This process helps you avoid expensive repairs later. It also keeps your home safe and comfortable. A special hvac evaluation finds hidden problems and safety risks, like gas leaks or carbon monoxide, that a basic home inspection might miss.
When you pick NEWEX, you get a home evaluation that leads to custom solutions. The technician uses special tools to find airflow problems and leaks. You get advice about upgrades, like high-efficiency units or smart thermostats. These custom ideas help you save energy, lower your bills, and have better indoor air quality.
