Out past the Austin Energy line — through Dripping Springs, Spicewood, Marble Falls, Liberty Hill, and most of the Hill Country's fastest-growing corridors — the pole at the end of your driveway probably belongs to Pedernales Electric Cooperative. PEC is the largest distribution co-op in Texas, and being a member rather than a customer comes with an under-used perk: the co-op runs its own rebate programs, and its members leave a startling share of that money unclaimed every year.
Part of the reason is visibility — co-op programs get a fraction of the marketing that big-utility programs do. Part is geography: Hill Country contractors span multiple utility territories, and not all of them bother tracking which co-op pays what. And part is the familiar paperwork gap between 'heard about a rebate once' and 'filed the form with the AHRI number attached.'
This guide closes that gap for the HVAC side: how PEC's programs are typically structured, what Hill Country homes tend to qualify for, the sequence that gets the money, and how it stacks with the federal 25C credit — which applies identically whether your meter says PEC, Bluebonnet, or Austin Energy.
The standing caveat, same as every rebate guide in this series: co-op program details — amounts, tiers, budgets — are living documents that change between program years. Use this as the map, then verify current numbers on PEC's official program pages or through a contractor who quotes co-op incentives in writing. The strategy is durable; the dollar figures are perishable.
Why PEC actively wants to pay you: Hill Country growth has the co-op adding load faster than almost any utility in Texas, and peak-day demand is expensive. Every high-efficiency heat pump replacing resistance heat or a dying builder-grade AC shaves the co-op's costliest hours. Member rebates are cheaper than new generation — your efficient equipment is, again, somebody's cheapest power plant.

Here's how to be that power plant, profitably.
PEC's residential incentive menu has historically centered on electrification and efficiency: rebates for qualifying heat pump installations (the flagship — the co-op has strong reasons to prefer heat pumps over resistance heat, and the rebates say so), plus programs in various years covering heat pump water heaters, smart thermostats, weatherization measures, and occasionally EV charging infrastructure — a co-op priority as Hill Country driveways electrify.
Magnitudes in recent program years have typically run from modest checks on thermostats to hundreds-to-four-figures on qualifying heat pump systems — with equipment tiers keyed to efficiency ratings in the same SEER2/HSPF2 language as everything else in this series. As always: current-year tables live on the co-op's site; contractors active in PEC territory quote from them directly.
Distinct co-op flavor worth knowing: member programs sometimes include bill-credit structures or financing options rather than pure checks, and the co-op's energy advisors will genuinely talk through a project by phone — a small-utility perk big-city customers don't get. Use it; it's your co-op.
The basics: active PEC membership on the service address, residential account, equipment meeting the program's current efficiency tiers, and filed paperwork with the standard supporting cast — invoice, AHRI certificate, model and serial numbers. Some programs require licensed-contractor installation documentation; all of them go smoother when the installer has done PEC paperwork before.
The Hill Country wrinkle that actually matters: many PEC-territory homes are all-electric — no gas line for miles — which makes the heat-pump-vs-resistance question the co-op's favorite subject. If your current system pairs an AC with electric strip heat (extremely common in 1990s–2000s Hill Country builds), a heat pump replacement is the single most rebate-favored, bill-favored move available: the strips demote from primary heat to backup, winter bills drop hard, and both the co-op program and the federal $2,000 credit aim squarely at the swap.
Well-and-septic acreage properties — Dripping Springs, Spicewood, Driftwood territory — should also flag the water heater: heat pump water heaters earn co-op attention and federal credit simultaneously, and garages out here have all the air volume the technology wants.
Quote stage: tell every bidder you're a PEC member and ask two questions — 'which equipment tiers clear PEC's current program,' and 'who files, you or me?' (Co-op programs are more often member-filed than Austin Energy's contractor-filed structure — knowing which is your job prevents the classic dropped baton.) Get qualifying model numbers and expected rebate amounts as written lines in the quote.
Purchase stage: build the same folder as the federal checklist — itemized invoice, AHRI certificate, manufacturer certification, serial numbers photographed at install. One folder feeds both applications.
Filing stage: submit the co-op paperwork inside any stated deadline window (post-install deadlines exist in some programs and are unforgiving), then claim 25C on Form 5695 at tax time. Stacked result on a qualifying heat pump: co-op money + $2,000 federal + off-season pricing — routinely a four-figure total reduction, out here where equipment quotes already run higher for drive-time reasons.
And if the contractor-search part is the friction: the network matches PEC-territory homeowners with licensed pros who work the Hill Country weekly and quote co-op incentives without being asked — which is, frankly, the tell you're hiring the right one.
PEC's structure rewards engagement in ways investor-owned utilities structurally can't, and rebate-hunting is the natural gateway to the rest. Capital credits: co-ops return margins to members over time — keep your address current with the co-op even after moving, because unclaimed capital credit checks are a genuine small-fortune category statewide. The annual meeting and board elections: rebate budgets and program priorities get set by a board you literally vote for; the five minutes of ballot participation is your program menu's upstream. Energy advisors: the co-op staffs humans who will discuss your specific project by phone without a sales agenda — validating a contractor's rebate claims against current program terms in one call. Outage and demand programs: beyond HVAC, PEC's various program years have included water heater timers, EV rate plans, and demand-response options that stack modest ongoing credits onto the equipment you just upgraded. None of this is glamorous; all of it compounds for the member who treats the co-op as theirs, which — uniquely in the utility world — it is.
One practical note peculiar to PEC territory: contractor coverage thins with the oak trees. Metro-based companies charge real trip premiums past Bee Cave, some decline far-out addresses entirely in peak season, and the contractors who genuinely work Spicewood, Marble Falls, and the acreage belts weekly are a smaller, more valuable roster — which affects rebate capture directly, because the installer who knows PEC's paperwork is disproportionately from that roster. When quotes seem scarce or padded out here, that's the geography talking, and the answer is matching into the local bench rather than dialing metro ads: the network's Hill Country pros price without the where-is-this-address premium and quote co-op incentives as routine. Combine the member-owner homework above with an installer who's filed PEC paperwork before, and the territory's rebate disadvantage inverts into an advantage: less competition for the money, and a co-op that answers its phone.
Final Hill Country footnote: co-op territory rewards planning ahead more than the metro does — contractor calendars run longer, parts ride further, and rebate paperwork adds its own clock. The acreage household that starts its heat pump conversation in September collects every layer without friction; the one that starts in the first freeze week joins a queue. Same equipment, same co-op, different experience — out here, the calendar is the concierge.
The whole guide in one sentence for the member in a hurry: confirm the logo on your bill, ask the co-op's energy advisors what the current heat pump program pays, make your contractor put qualifying model numbers and filing responsibility in writing, stack the federal credit at tax time — and let being a member-owner mean what it's supposed to mean: the utility working for you, visibly, in the project's bottom line.
