AC & Heat Pump Professional Exam Dates 2026: Testing Windows, Deadlines & Scheduling

Why There's No Fixed "Testing Window" for This Credential

If you've researched other certifications that also go by "AC & Heat Pump Professional," you may expect a published calendar of quarterly testing windows with hard registration cutoffs. That's not how the Building Performance Institute (BPI) runs its AC & Heat Pump Professional program. BPI administers this credential through a network of independent BPI Test Centers, and candidates schedule their online and field examinations directly with a center rather than waiting for a centralized testing cycle.

In practice, this means "exam dates" for 2026 are really a function of test center availability in your region, not a fixed BPI-wide schedule. Your real scheduling task is threefold: confirm your prerequisites, book a center with open slots for both the online exam and the separate field exam, and manage the 12-month clock that starts once you sit for your first attempt.

Two Scheduling Pathways for 2026

BPI's Core Certification Scheme Handbook, revised April 9, 2026, lays out two distinct routes to the AC & Heat Pump Professional credential, and which one applies to you changes how you should plan your calendar.

• New-candidate pathway: 100 multiple-choice online questions in a two-hour session, plus a separate two-hour field examination.
• Core-holder pathway: If you already hold a BPI Core certification, you take a shorter 50-question online exam in 90 minutes, plus the same field examination.

Because the online session length and question count differ so much between the two tracks, block out different amounts of preparation time depending on which pathway you're using. Candidates coming in fresh, without a Core credential, should treat the 100-question online exam as the larger of the two milestones and schedule accordingly.

For a full breakdown of what's actually tested and how the exam is structured domain by domain, see the AC & Heat Pump Professional Exam Domains 2026 guide, and for a difficulty-focused perspective on both pathways, review How Hard Is the AC & Heat Pump Professional Exam?.

Before You Book: Prerequisites to Confirm

Before you contact a BPI Test Center to reserve a date, confirm you meet the credential's core eligibility requirement: an active EPA Section 608 Type II or Universal certification. This is a hard requirement for the credential itself, separate from the exam content. Note that a specific training course is not mandatory to sit for the exam - you can self-study, take a course, or combine both, but the EPA 608 credential must be in place.

If you're still sorting out whether you meet all eligibility criteria, the AC & Heat Pump Professional Requirements guide walks through eligibility in more detail, and AC & Heat Pump Professional Certification covers how the credential fits into the broader BPI Core Certification Scheme.

Exam Day Format and Timing

Once you've booked a date, know exactly what the clock looks like on test day:

• Online exam: Closed book, except that BPI Standards are provided through the testing site itself - you don't need to memorize standard citations, but you do need to know how to navigate and apply them under time pressure.
• Field exam: Open book, but you may not receive assistance from another person. You can bring reference materials, but the two-hour clock still requires fluency, not page-flipping for every question.

Passing thresholds differ by component. The online exam requires a 70% score. The field exam requires 70% overall and at least 85% on the CAZ (combustion appliance zone) and CO (carbon monoxide) sections specifically - meaning you can't average your way past a weak combustion-safety performance. For a deeper look at exactly how these thresholds are calculated, see the AC & Heat Pump Professional Passing Score guide.

Domain Weighting You're Scheduling Around

The six domains below apply to the online examination, and their weights should directly influence how much study time you schedule for each before your booked date:

Domain 5 carries the most weight at 25%, followed closely by Domains 3 and 4 at 20% each. If your booked exam date is approaching and you have to prioritize, spend disproportionate time on optimization, measurement and verification, and standards application - together they account for 65% of the online exam. A domain-by-domain study plan is covered in the AC & Heat Pump Professional Study Guide.

Field Exam Scheduling Considerations

Don't assume the field exam happens automatically on the same day as your online session. Confirm with your BPI Test Center whether both components are scheduled together or on separate dates - this varies by location and availability. Because the field exam has its own two-hour time block and separate pass/fail criteria, plan your travel and preparation as if it were a distinct appointment, even if it's on the same calendar day.

The field exam uses its own weighting structure, separate from the online domains:

Optimization dominates the field weighting at 40%, echoing its prominence on the online exam. If you schedule your field exam for a later date than your online exam, use the gap to focus specifically on hands-on optimization tasks rather than re-reading standards material you've already covered.

The 12-Month Certification Completion Clock

Here's the scheduling detail that trips up the most candidates: you must complete certification - meaning both the online exam and the field exam - within 12 months of your first examination attempt. If you pass the online exam in February but delay the field exam past the 12-month mark, that clock matters. Build your field exam booking into your calendar the same week you book your online exam, not as an afterthought.

For candidates weighing whether the overall time and cost investment makes sense given this 12-month structure, the ROI analysis and certification cost breakdown are useful companion reads.

Building a 2026 Study Calendar Around Your Test Date

Once you've locked in dates with your BPI Test Center, work backward. The study timeline below assumes roughly six weeks of preparation for the new-candidate pathway, sequenced by domain weight and by which topics carry over most directly into the field exam.

You can run realistic timed practice sessions through our practice test platform to get comfortable with the 100-question, two-hour online format before your actual booked date, and cross-check your readiness against the AC & Heat Pump Professional Cheat Sheet in your final week.

Renewal Deadlines to Put on Your Calendar Now

Scheduling doesn't end once you pass. The AC & Heat Pump Professional credential lasts three years, so mark your renewal deadline on your 2026 calendar the moment you certify. Two waiver paths affect how much re-testing you'll need to schedule at renewal:

• Online exam waiver: 30 relevant continuing education units (CEUs) completed during the renewal period can waive the online examination entirely.
• Field exam waiver: 3,000 verified relevant work hours during the preceding three years can waive the field examination, but only for the first or second renewal.

The renewal application fee is $360 for a single certification when the field exam is waived; if you still need to sit for the online exam at renewal, that exam fee is charged separately and is distinct from an initial examination fee. Plan your CEU accumulation and documentation of work hours well before your three-year deadline arrives - waiting until the final month to gather CEU records is a common, avoidable scheduling mistake.

See the cost breakdown article for how renewal fees compare to initial certification expenses, and AC & Heat Pump Professional Jobs for how employers in the field typically view active versus lapsed credentials.
