The short answer
Pennsylvania has no statewide HVAC license. To check an HVAC contractor, look up their Home Improvement Contractor registration with the Attorney General, ask for a current liability insurance certificate, confirm EPA Section 608 certification for refrigerant work, and ask who pulls the municipal permit. The registration number should appear on the contract.
Pennsylvania has no statewide HVAC license, so there is no single license number to look up. Instead, check four things: the contractor's Home Improvement Contractor registration with the Attorney General, proof of liability insurance, EPA Section 608 certification for anyone handling refrigerant, and who is pulling the municipal permit. Then make sure the written contract meets state rules. This is general information, not legal advice.
Why there is no state HVAC license to look up
Many states license HVAC contractors through a trade board. Pennsylvania does not. A few cities, including Philadelphia and Pittsburgh, issue their own HVAC or mechanical licenses, but Lancaster County boroughs such as Mount Joy, Lititz, Elizabethtown and Manheim generally do not. When an ad around here says "licensed," ask exactly which license it means and who issued it.
Electrical and plumbing work tied to an HVAC job, such as a new circuit for a heat pump or gas piping for a furnace, may fall under local rules and inspections. The permit process covers most of that, as described below.
HIC registration under HICPA
Pennsylvania's Home Improvement Consumer Protection Act, usually called HICPA, requires most contractors who do home improvement work to register with the Office of Attorney General. Registered contractors must show their Pennsylvania registration number in their advertising and on their contracts, so look for a number that starts with "PA" in ads, on the website and on the paperwork.
You can check that number with the Attorney General's online lookup at hicsearch.attorneygeneral.gov. Confirm the business name matches the name on your contract exactly. Keep in mind what registration is and is not: it is a consumer protection measure, not a skills test, so it tells you the business is on record with the state, not that its technicians are good at diagnosing a cracked heat exchanger.
What HICPA says a contract should include
For home improvement jobs above a small dollar threshold, HICPA requires a written contract signed by both parties. Among other items, the contract should include:
- The contractor's name, address and HIC registration number.
- A description of the work and the equipment, ideally with model numbers.
- The total price, plus any deposit and payment schedule.
- The approximate start and completion dates.
- A notice of your right to cancel within three business days of signing.
- Any change-order terms, signed by both parties.
If a replacement quote is a single line with a total, ask for more. A complete quote also names the efficiency rating, states whether a Manual J load calculation was done, and lists permits, removal, the condensate drain and any duct or electrical changes.
Warning signs during a sales visit
- No registration number on the estimate, or a number that belongs to a different business name.
- Pressure to sign the same day, or a claim that a price disappears if you take the weekend to think.
- A request for a large cash deposit before any equipment is ordered.
- An offer to skip the permit to save time, or a suggestion that you pull it yourself as the homeowner.
- Sizing based only on the old unit's label or the square footage, with no measurements taken in the house.
None of these alone proves a contractor is dishonest, but each one is worth a direct question. A good contractor will answer it plainly and put the answer in writing.
Proof of liability insurance
HIC registration requires contractors to carry liability insurance, but coverage can lapse after registration. Ask for a current certificate of insurance, and if the job is large, ask the contractor's insurance agent to send it to you directly. If the contractor has employees, ask about workers' compensation as well. A ladder fall or a fire caused by a bad gas connection should land on the contractor's policy, not yours.
EPA Section 608 for refrigerant work
Federal law requires anyone who opens a refrigerant circuit to hold EPA Section 608 certification. That covers recharging an AC, replacing a compressor, brazing a line set or recovering refrigerant from an old unit. Home split systems fall under Type II, and many technicians hold Universal certification. It is a card the technician carries, so ask to see it.
This matters more now. R-22 production ended on January 1, 2020, and new equipment since 2025 uses A2L refrigerants such as R-454B and R-32, which call for updated handling practices. Anyone topping off an old R-22 system or installing new A2L equipment without certification is breaking the rules.
| Credential | Who issues it | How to check |
|---|---|---|
| HIC registration | PA Office of Attorney General | Online lookup by number or name |
| Liability insurance | Contractor's insurer | Current certificate of insurance |
| EPA Section 608 | EPA-approved certifying organization | Ask to see the technician's card |
| Building or mechanical permit | Your municipality or its code agency | Ask who pulls it; call the code office |
Permits under the Uniform Construction Code
Pennsylvania's Uniform Construction Code is enforced locally. Each borough or township has a code official, and some use a third-party inspection agency. Replacing a furnace, adding a heat pump, running a new gas line or converting an oil boiler usually needs a permit and an inspection. A typical call from an older Lititz house involves a steam boiler repair that turns into a replacement; the new boiler's venting and chimney liner are exactly what an inspector checks. The contractor normally pulls the permit, so ask who is responsible and whether the price includes it.
How Your Comfort Air Pros fits into this
We are not the contractor on your job. We answer the phone 24/7 and connect callers with independent local HVAC contractors who do the work. Every HVAC technician we send is licensed where Pennsylvania requires it, and insured. The contractor performing the work should give you its own HIC registration number on the written contract, and you can verify it with the Attorney General. You can read more about how we work on our about page.

Reading an HVAC contract before you sign
Most problems with HVAC jobs can be spotted in the paperwork. Under the Home Improvement Consumer Protection Act, a written contract should carry specific details, and a few others protect you even where the law is silent. Before signing, check that it shows:
- The contractor's PA HIC registration number, matching the name on the Attorney General's lookup.
- The names of any subcontractors known at signing. If one company sells the job and another installs it, both should be clear to you.
- Start and completion dates that are realistic, not left blank.
- A deposit that respects the law. For larger jobs, HICPA limits the down payment to one-third of the contract price plus the cost of special-order equipment. A demand for more, especially in cash, is a warning sign.
- Model numbers and the AHRI match for new equipment, so the system installed is the one you priced.
- The three-business-day cancellation notice for contracts signed in your home.
None of this is legal advice, and the Attorney General's office is the authority on HICPA. But a contractor who resists putting these details in writing is telling you something. Our AC and furnace installation page lists what the quote itself should itemize.
When to call and what to ask on the first visit
If you are planning a furnace or AC installation or need a repair now, call (321) 478-0693. Calls are answered 24/7, and you get a price before any work starts. When the technician arrives, ask for the contractor's HIC number, the certificate of insurance and the EPA 608 card. If you are deciding between fixing and replacing an older system, our repair or replace guide is a good next read.
Quick answers
Does a handyman need HIC registration to replace my thermostat?
Registration rules depend on the business and the size of the work, with some exemptions. For anything beyond a simple swap, especially work on a furnace, heat pump or gas line, hire a registered contractor and check the number online. A thermostat on a heat pump with auxiliary heat is easy to wire wrong, so experience matters too.
What if the contractor's registration number doesn't show up in the lookup?
First check for typos and try searching by business name. Registration can lapse, and some businesses operate under a different legal name than the one on their truck. If you still cannot find it, ask the contractor to explain before you sign or pay a deposit. You can also contact the Attorney General's consumer protection office with questions.
Do I need a permit to replace an AC with the same size unit?
Often yes. Many Lancaster County municipalities require a permit for replacing HVAC equipment, even a like-for-like swap, because it involves electrical connections and sometimes refrigerant lines. Requirements vary by borough and township, so ask the contractor or call your local code office before work begins.
