HVAC Permits — Free Consultation & Quote

New System? Old Install That Was Never Permitted?

Heating and cooling work is one of the most common permit requests we get. A new AC condenser, a split unit, a heat pump or an oil-to-gas boiler conversion usually needs a permit from your town, city or village, and so does moving a boiler. Just as often, homeowners find out an older system was installed without a permit, or the permit was never closed.


We handle HVAC permits across the Towns of Hempstead, North Hempstead and Oyster Bay, the Cities of Glen Cove and Long Beach, and the villages.

HVAC & Mechanical Jobs We Handle

  • AC condensers and central air
  • Ductless split units
  • Heat pumps
  • Oil-to-gas boiler conversions
  • Boiler relocations (often with a plumbing permit)
  • Legalizing AC and HVAC work done without a permit
  • Closing out open mechanical permits
  • AC and HVAC violations: we review the notice and handle the permits and inspections needed to cure it

What an HVAC Permit Usually Involves

Every municipality handles mechanical permits its own way, and some list central A/C as its own permit type in their online portal. Depending on the job, your town may want drawings, a survey, and electrical or plumbing sign-offs. We tell you exactly what applies in your free consultation, coordinate the sign-offs, and handle the filing.


If your HVAC work is part of a bigger project, like a finished basement, an addition or a garage conversion, we fold it into the same permit process so nothing gets missed.

Why Open HVAC Permits Matter

An AC or boiler permit that was opened and never signed off stays on your property's record. It often turns up when a buyer's attorney orders a search before a sale. Closing it out ahead of time keeps your sale or refinance on track.

How It Works

  1. Free consultation. Call or text 516-399-0139, or send your name and phone number, then the property address and the equipment.
  2. Records review. We check your property's permit history.
  3. Paperwork and filing. We line up what the town needs and file with your town, city or village.
  4. Comments. We answer reviewer comments and resubmit.
  5. Inspections and close-out. We coordinate sign-offs and inspections until the permit is closed.


Timing: simple jobs typically take 2–4 weeks; more complicated or mixed jobs typically take 4–8 weeks. It varies by town and scope and is never guaranteed.

HVAC Permit Questions

Does a new AC condenser need a permit?

AC condensers are one of the most common permit jobs we file. Rules vary by town, city and village, so we confirm what applies to your property.


Can you legalize a split unit or heat pump that was installed without a permit?

Yes. Legalizing AC and HVAC work is part of what we do.


Do you install HVAC equipment?

No. We're permit expediters. We handle the permits and town process; your HVAC contractor does the installation.


I'm a contractor. Can you file for my customers?

Yes. We work with contractors and handle filing, town comments and inspections.
