Boiler and steam heat specialists
Given how many Newark buildings still run on steam or hot-water heat, some local companies focus heavily on boiler service, radiator repair, and steam system balancing. These companies tend to have more experience with older cast-iron piping and multi-family heating loops.
Full-service HVAC contractors
Many Newark-area companies handle both heating and cooling, including furnace and central AC installs for the smaller share of homes with ductwork, alongside boiler work. These generalists are often a good fit if you need multiple systems serviced.
Ductless and mini-split installers
As more Newark landlords retrofit cooling into older buildings, several local contractors have built expertise specifically in ductless mini-split design and installation, which requires different planning than a central AC job.
What to check before choosing a company
Confirm the company's technicians hold current licensing with the New Jersey State Board of Examiners of Master HVACR Contractors, and ask whether they pull permits through Newark's Division of Construction Code Enforcement for larger jobs.
It's also worth asking directly about experience with your specific system type, since a company skilled at central AC installs isn't necessarily the best fit for a steam boiler repair.

Common questions
Should I hire a boiler specialist or a general HVAC company?
If your main issue is steam or hot-water heat, a company with specific boiler experience is often a better fit than a generalist focused mainly on central air.
Do Newark HVAC companies handle multi-family properties?
Many do, and it's worth confirming a company has experience coordinating work across occupied units before hiring for a multi-family job.
How do I know if a company is licensed in New Jersey?
You can confirm license status through the New Jersey State Board of Examiners of Master HVACR Contractors before signing any contract.
Are there companies in Newark that specialize in ductless systems?
Yes, given the number of retrofits needed in older buildings without ductwork, several local contractors focus specifically on ductless mini-split design and installation.
