Do You Need a Permit to Replace an AC or Furnace in Amarillo, TX?

If a contractor tells you a like-for-like AC change-out in Amarillo “doesn’t need a permit,” this page is the one to read before you agree. The City of Amarillo publishes exactly which work is exempt from a permit, and a new condenser, air handler, heat pump or furnace is not on the list. This guide walks through what the city’s exempt-work page says, who issues the permit depending on where the house actually sits — Amarillo, Canyon, or unincorporated Potter and Randall County — how the permit gets pulled, and what the permit does and does not tell you about the company doing the work.

Palo Duro Air Repair is an independent referral service, not an HVAC contractor. We explain the rules; the Building Safety Division applies them to your address, and a call to 806-378-3041 settles any question this page leaves open.

What the city’s own exempt-work list says

The City of Amarillo’s Building Safety Division publishes a page titled Work Exempt – From Permit. It opens by saying that most construction projects require a permit from the city as described in International Residential Code Section 105, and that any owner or authorized agent who intends to construct, enlarge, alter, repair, move or demolish — the list continues through the code’s standard verbs — shall first make application to the building official and obtain the required permit. Then it lists what does not need one. Under Mechanical, the exempt items are:

1. Portable heating appliances.
2. Portable ventilation appliances.
3. Portable cooling units.
4. Steam, hot or chilled water piping within any heating or cooling equipment regulated by the code.
5. Replacement of any part that does not alter its approval or make it unsafe.
6. Portable evaporative coolers.
7. Self-contained refrigeration systems containing 10 pounds or less of refrigerant and actuated by motors of 1 horsepower or less.
8. Portable fuel-cell appliances that are not connected to a fixed piping system and are not interconnected to a power grid.

Nothing on that list is a central air conditioner, a heat pump, a furnace, an air handler or a split-system replacement. A window unit or a plug-in portable is exempt; a new condenser on a pad is not. The page does not use the words condenser, air conditioner, furnace, heat pump or change-out anywhere — it does not need to, because the exempt list is the exception and the permit requirement is the rule.

That is also the honest limit of what we can tell you. We read the city’s exempt list and the city’s statement of the general rule; we did not read a city sentence that says “AC replacements require a permit” in those words. The conclusion follows from the list, and it is the same reading every Texas city working from the International Residential Code applies — but the office that applies it in Amarillo is the Building Safety Division, and it will confirm your specific project in a two-minute call.

The “part” line, and where it gets stretched

Item 5 is the one contractors reach for. It covers the replacement of a part that does not alter the equipment’s approval or make it unsafe — a capacitor, a contactor, a blower motor, a thermostat, a control board. Components inside equipment that stays in place. Replacing the equipment itself is not a part replacement, and a contractor who describes a full condenser swap as “just swapping a part” is describing it to you, not to the inspector.

The genuinely gray cases — an evaporator coil, a compressor replaced inside an existing condenser — are calls the building official makes, and this guide does not make them for you. Ask Building Safety how it classifies the job before the work is scheduled, not after.

The page also carries a sentence worth quoting: exemptions from the permit requirements shall not be deemed to grant authorization for any work to be done in any manner in violation of the code or any other laws or ordinances of the city. Exempt does not mean unregulated. A portable unit still has to be plugged into a circuit that can carry it.

Who issues the permit depends on where the house is

An Amarillo mailing address does not tell you which building department you are dealing with. Three answers are possible.

Inside Amarillo city limits — City of Amarillo Building Safety Division. Residential work is administered under the 2021 International Residential Code with city amendments. The division issues permits electronically through its MGO Connect portal, with in-person help at the Simms Municipal Building, 808 S Buchanan St, Suite 104, Amarillo, TX 79101, Monday to Friday 8:00 am to 5:00 pm. Phone 806-378-3041 or 806-378-3085; email [email protected]. The current permit fee is on the city’s Building Safety Fees page; we do not reproduce it here because fee schedules change and the number is the city’s to quote.

Inside Canyon — City of Canyon Planning & Development Department, 301 16th St., Canyon, TX 79015, (806) 655-5014. Canyon requires a permit to construct, enlarge, alter or repair a building. Whether Canyon treats an HVAC-only replacement the way Amarillo does is a question we have not verified against a Canyon mechanical rule, so ask that office directly. Our Canyon service-area page covers the practical differences for homeowners there.

Unincorporated Potter or Randall County, including Bushland — no city building department. Texas counties have only the limited permitting authority state law grants them (floodplain, subdivision, on-site sewage), not a general residential building-permit program. That means two things for a Bushland homeowner: do not accept a contractor’s claim of an “Amarillo permit” for an address outside the city, because the city has no jurisdiction there; and do not read “no permit” as “no standards” — the state license, the manufacturer’s installation instructions and your own written contract are doing the inspector’s job, so read the bid harder.

Not sure which side of a line a parcel is on? The county appraisal district’s record for the address will say, and so will the question “who pulled the last permit on this house?”

How the permit actually gets pulled

1. Work out the jurisdiction. City of Amarillo, City of Canyon, or unincorporated county, as above.
2. Put permit responsibility in the written bid. The normal arrangement is that the TDLR-licensed contractor applies for the permit under its own name and shows the fee as a line item. Get that in writing. A contractor who wants you to apply yourself so their name stays off the record is telling you something.
3. Have the equipment details ready. Tonnage and model of each new piece, refrigerant type, whether the disconnect, breaker or gas line changes, whether any ductwork is replaced. The inspector and the application both work from the same facts a complete bid already contains.
4. Apply through Building Safety — MGO Connect online, or the Suite 104 counter.
5. Schedule the inspection and keep the record. The permit holder or their agent must notify the building official when the work is ready; the city says it schedules inspections for the next business day. Keep the permit number with the invoice and the warranty registration.

Permit, license and insurance are three different pieces of paper

The permit says the city will inspect the installation. It says nothing about who is doing it.

The license is the state’s business. Texas requires an Air Conditioning and Refrigeration Contractor license from the Texas Department of Licensing and Regulation for HVAC contracting work — there is no city or county contractor license that substitutes for it — and the license, not the permit, is what makes a company legally able to take the job. Check the licensed name against the bid and the permit application; our TDLR license lookup guide walks through the search field by field.

Insurance is the company’s. The license requires liability coverage to be in force, but it does not tell you the policy is current this month or what it excludes. Ask for the certificate and call the agent on it.

Why the inspection matters more in Amarillo than it sounds

A replacement system here spends its first summer running through July highs in the low nineties and its first spring sitting under a hail season that peaks in April and early May, with a second, smaller one in September and October. The failures that surface in those first two years — a condenser sized for the floor plan rather than the house, a line set reused when it should have been flushed, a disconnect or breaker that does not match the new nameplate, a condensate drain that was never tested — are exactly what an inspector looks at and a homeowner cannot see from the driveway. The permit does not make a bad installer good, but it puts a second set of eyes on the work before the attic hatch closes. And when a hailstorm takes out that condenser two springs from now, the insurer’s adjuster will ask when it was installed and by whom; a permit record answers both.

A bid that skips the permit is not a discount. It is a line that reappears as your problem at resale, at claim time, or at the warranty desk.

What this page deliberately doesn’t tell you

The permit fee and the late-fee amount, plan-review turnaround, the exact inspection sequence for a change-out, whether a homeowner may pull their own mechanical permit, whether a coil or compressor swap counts as “a part” in the building official’s reading, and Canyon’s mechanical-specific rule are all calls the issuing office makes, and none is stated here because none could be read from an official document for this guide. The Building Safety Division (806-378-3041) and Canyon Planning & Development ((806) 655-5014) will each answer in a few minutes. Treat any contractor’s version of those answers as a claim to check.

Want a pro who pulls the permit for you?

Ask any company you are matched with to pull the permit as part of the replacement and show it on the bid. Send one request through Palo Duro Air Repair and it goes to an independent, TDLR-licensed HVAC contractor serving Amarillo, Canyon and Bushland; then run the license lookup and the permit question past them yourself before you sign. For what the job should cost first, start with the AC replacement cost guide.
