Common questions
Where should I start if I'm deciding whether to replace my system?
Start with the repair-or-replace guide. It walks through the factors we weigh, the questions to ask, and why age alone doesn't decide it.
Are heat pumps a good fit for Portland and Vancouver?
Many homes here use heat pumps for both heating and cooling. The heat pump guide explains how they work in cold snaps, what defrost and auxiliary heat mean, and what to ask before you choose one.
Is the federal heat pump tax credit still available?
No. The federal Energy Efficient Home Improvement Credit (25C) ended for equipment placed in service after December 31, 2025. Local utility programs may still apply — see the incentives guide.
How often are these guides updated?
Each guide shows its last-updated date. Incentive and program details are rechecked against the program's own page before we rely on them.
