HVAC compliance includes EPA Section 608 technician certification, state or local mechanical or HVAC licensing, permits and inspections for installations, and rules on refrigerant recovery and disposal. Some areas require separate gas licensing.

Who to ask and what to ask
| Office | Question |
|---|---|
| State licensing board | Which HVAC or mechanical license do I need to contract? |
| EPA Section 608 | Which certification type covers my work? |
| County and city building departments | Do equipment changeouts need permits and inspections? |
| Utility or energy office | Are there rebate programs and installer requirements? |
| Insurance agent | What coverage do builders and property managers require? |
Sample changeout permit flow
For a typical furnace and air conditioner replacement, the contractor pulls the mechanical permit before work, installs equipment to the manufacturer's instructions and local code, performs startup and records readings, and schedules the inspection. The inspector may check clearances, venting, gas connections, electrical disconnects and condensate disposal. Keep the permit number and readings in the job file; future buyers and warranty claims may need them.
Refrigerant rules in plain terms
Under EPA's Section 608 program, technicians must be certified for the type of equipment they service, must use certified recovery equipment, and may not knowingly vent refrigerants. Businesses that dispose of appliances follow rules on refrigerant recovery before disposal. Rules have changed over the years as refrigerants are phased down, so check EPA's current guidance for the refrigerants you handle and keep records the rules require.
Rules owners often miss
Some states require HVAC contractors to carry specific insurance limits; check before bidding builder work.

Common questions
What is EPA 608?
Certification for refrigerant handling.
Do replacements need permits?
Often yes.
Can I vent refrigerant?
Intentional venting is prohibited under EPA rules.
Can I recover refrigerant without certification?
No. EPA requires Section 608 certification for technicians who maintain, service, repair or dispose of equipment that could release refrigerants.
Do I need a separate license for gas piping?
In many places, gas piping work requires specific licensing or permits. Ask your building department.
Do I need a separate license for refrigeration?
Commercial refrigeration may have separate licensing in some states.
Do I need a license to sell maintenance plans?
Usually not beyond your contractor license, but check consumer contract rules in your state.
