Do I need a permit to replace my furnace or AC in Visalia, CA?

Yes. The California Energy Commission's 2025 Energy Code guidance states that installing a space-conditioning appliance other than a plug-in room unit requires a building permit, and in Visalia that permit comes from the City of Visalia Building Division (559-713-4300). This applies to a like-for-like changeout, not just a brand-new system.

Who pulls the HVAC permit — me or the contractor?

Normally the licensed C-20 contractor doing the work pulls it, and the quote should say so as a line item. If a contractor asks you to pull an owner-builder permit for work they are performing, or suggests skipping the permit altogether, treat it as a reason to get another quote.

Why is there a duct test on my HVAC quote?

Because the Energy Code requires it for most changeouts. The Energy Commission says field verification and diagnostic testing is prescriptively required for most HVAC alterations, that replacing only the outdoor or indoor unit of a split system by itself triggers duct sealing and verification, and that existing ducts must test to no more than 10% total leakage or 7% leakage to outside. The test is done by the installer and an independent rater and is listed on the CF1R compliance form.

What is an ultra-low-NOx furnace and why does Visalia require one?

Visalia is in the San Joaquin Valley Air Basin, where the air district's Rule 4905 says a natural-gas fan-type central furnace under 175,000 Btu/hr may only be sold or installed if it is certified to a 14 nanograms-per-joule NOx limit — the standard the trade calls ultra-low-NOx. The rule has no exemption for replacements, so the model number on a Visalia furnace quote should be a certified unit.

Can I use California's $1,000 minor-work exemption to skip the permit?

No. The exemption (CA-007, AB 2622) applies only when all three conditions hold — the whole job is $1,000 or less, it needs no permit, and no one else is employed on it. An HVAC changeout needs a permit by itself, so the exemption never reaches it regardless of price, and the work is CSLB C-20 contractor work.

Q: How much does an HVAC permit cost in Visalia?

The city's fee schedule isn't reproduced here. For scale, permits run $50–$300 nationally for a furnace replacement, and the Visalia full-system permit figure this site cites from local project data is around $225 — ask the Building Division at 559-713-4300 or have the contractor itemize it on the quote.

Short answer: as of October 2026, replacing a furnace, air conditioner or heat pump in Visalia, CA requires a building permit from the City of Visalia Building Division (559-713-4300) — the California Energy Commission's guidance is that installing any space-conditioning appliance other than a plug-in room unit "requires a building permit." Expect the Energy Code's field verification testing on your ducts, and for a gas furnace expect a model certified to the San Joaquin Valley air district's ultra-low-NOx limit. None of this is optional, and all of it belongs on the written quote. Call (559) 555-0142 to get matched with a licensed local C-20 contractor who handles it as a matter of course.

1. The permit: yes, even for a like-for-like swap

Homeowners often assume a permit is for new construction and a straight replacement slides under it. In California it doesn't. The Energy Commission's own support page for the 2025 Energy Code states that "installation of a space conditioning appliance (other than a plug-in room appliance) requires a building permit," and that rule is what makes the statewide $1,000 minor-work exemption irrelevant here: the exemption (CA-007, AB 2622, effective January 1, 2025) applies only when a job is $1,000 or less and needs no permit and involves no one else on the payroll. An HVAC changeout fails the second test on its own, whatever it costs — which is also why it is CSLB C-20 contractor work rather than a handyman job (see how we match licensed C-20 contractors).

Inside Visalia city limits the permit is issued by the City of Visalia Building Division, 559-713-4300. Outside the city — Tulare, Exeter, Porterville, Hanford, or an unincorporated parcel — the permit comes from that city or from the county, and this guide doesn't try to speak for those offices; your contractor should name the right one on the quote. The contractor normally pulls the permit and schedules the inspection, and the quote should show both as line items.

2. The Energy Code: why there's a duct test on your quote

California's building energy code (Title 24, Part 6 — the "Energy Code") treats a replacement as an alteration, and alterations carry their own requirements. From the Energy Commission's 2025 guidance:

Field verification and diagnostic testing "is prescriptively required for most HVAC additions and alterations." An independent rater — the Commission's term is ECC-Rater; the trade still says HERS rater — verifies the work, in addition to the city inspector.
Replacing only part of a split system still triggers it. "Replacing the outdoor unit (or indoor unit) of a split system by itself will trigger the duct sealing" and field-verification requirements. Swapping just the condenser does not avoid the duct test.
Existing ducts have to pass a leakage test — "no greater than 10% total leakage or 7% leakage to outside," tested by the installer and the rater. If an older duct system can't meet it, the Commission describes a smoke-test-and-visual-verification fallback; in practice that is the point at which a quote grows a duct-sealing or duct-repair line.
Refrigerant charge verification is required "in all climate zones for heat pumps and in climate zones 2 and 8 through 15 for air conditioners." Which climate zone your address is in is shown on the compliance form — ask the contractor rather than guessing.
The paperwork is the CF1R. "Any FV&DT that is required for a project will be specified on the Certificate of Compliance (CF1R)." If you want to know exactly which tests your job carries, that form is the answer.
Refrigerant recovery from the old system "requires refrigerant recovery by a technician that holds an EPA 608 Type II or Universal certificate" — it cannot simply be vented.

What this means for the price: the rater's test is a real line item, and a duct system that fails it adds work. Nationally, a duct leak repair runs $200–$700 and the permit itself $50–$300; the Visalia full-system permit figure this site cites from local project data is around $225. A quote that is noticeably cheaper than the others is worth checking against this list before anything else — the common way to undercut on an HVAC changeout is to leave the permit and the testing out.

3. The air district: ultra-low-NOx furnaces only

Visalia sits in the San Joaquin Valley Air Basin, and the San Joaquin Valley Air Pollution Control District's Rule 4905 (amended March 19, 2026) says no one may "supply, sell, offer for sale, install, or solicit the installation" of a natural-gas fan-type central furnace under 175,000 Btu/hr in the basin unless the unit is certified to the rule's NOx limit — 14 nanograms per joule for every residential category, in force for condensing and non-condensing units since 2015. The rule contains no exemption for replacing an existing furnace.

Practically, every furnace a Visalia C-20 contractor quotes should already be a certified "ultra-low-NOx" model, and this rarely causes trouble. Where it matters is comparison shopping: a furnace price found online, or quoted by a company based outside the valley, may be for a unit that cannot legally be installed in Tulare County, so it isn't a like-for-like number. Ask that the model number on your quote be a Rule 4905-certified unit; the furnace replacement cost guide covers what the rest of a furnace quote should contain.

What each kind of changeout runs into

The same three layers — city permit, Energy Code testing, air-district rule — land differently depending on what's being replaced. Using only what the Energy Commission and the air district actually state:

Gas furnace only. Permit; the Rule 4905 ultra-low-NOx certification; and, because a furnace swap is an HVAC alteration on an existing duct system, expect the duct-leakage test to be on the CF1R. Pricing is on the furnace replacement cost guide.
Outdoor AC unit only. Permit, and — the one that surprises people — the duct test anyway: replacing "the outdoor unit (or indoor unit) of a split system by itself" triggers duct sealing and verification. Refrigerant-charge verification applies in the Commission's listed climate zones; check which zone your address is in.
Full system (furnace + AC). Everything above at once, which is why the permit and testing lines on a full replacement quote are larger than on a single-component job — but you pay them once instead of twice.
Heat pump. Permit, duct test on existing ducts, and refrigerant-charge verification "in all climate zones for heat pumps." No gas furnace means Rule 4905 doesn't apply to the heat pump itself. See heat pump repair and replacement.
Repairs. This page is about replacement. A component repair on an existing system is a different question that this site doesn't answer with a blanket rule — ask the contractor whether the specific repair is permitted work, and see the AC repair guide for what repairs cost.

Timing: the rater's testing happens after the equipment is in and before the city's final inspection, so a changeout that is "done" the day the crew leaves isn't closed out until both have happened. Ask what date the final is scheduled for.

4. What happens at inspection

The city's inspection is separate from the rater's testing. In general terms the inspector is confirming that the installed equipment matches the permit, that the installation is complete and safe to operate, and that the required compliance paperwork is in order; the rater's job is the energy-performance measurements described above. The contractor schedules the inspection, and the job isn't finished until it passes — a permit that is pulled but never finaled is a loose end that can resurface when the house is sold. This page deliberately doesn't list a city inspection checklist, because the City of Visalia's own HVAC handout wasn't available to us when it was written; the Building Division at 559-713-4300 can tell you exactly what its inspectors look for.

5. How to confirm your changeout is permitted and tested

Check the license first. Look up the contractor's CSLB C-20 status at cslb.ca.gov ("Check a License") before signing anything.
Find the permit on the quote. It should be a named line item that says who pulls it. If it isn't there, ask — and notice how the question is answered.
Find the testing on the quote. Ask whether the duct-leakage test and any other field verification is included and who the independent rater is. The CF1R lists what's required.
Check the furnace model. For gas heat, confirm the quoted model is certified under Rule 4905.
Confirm with the city afterward. Ask the contractor for the permit number and the final inspection result, or confirm with the Building Division at 559-713-4300.

Who's licensed to do this work

Furnace, AC and heat pump replacement in California is CSLB C-20 (Warm-Air Heating, Ventilating and Air-Conditioning Contractor) work (claude_FACTS_CA_STATE.md CA-006). The permit, the Energy Code testing and the air-district rule all assume a licensed contractor is doing the job; none of them is a reason to attempt the work unlicensed, and the $1,000 exemption doesn't apply. Verify any contractor yourself at cslb.ca.gov before hiring.
