At Perennial DC Heat Pumps we built two free planning tools for ducted heat pump projects in Washington, DC. Use the estimator when your question is what a job like yours costs with us. Use the assessment when you aren’t sure what system you have, who has to approve the work or what to ask next. Neither tool asks for contact details to show a result, and neither replaces our site visit or written estimate.
Start with the question on your mind
Wondering what it will cost and wondering what you actually have are two different questions. You may know you want a replacement and still need a price, or know you want a warmer upstairs without knowing what equipment the house uses. Start with the tool that matches what you don’t know. If both are open, start with the assessment so the system and approvals are sorted first. “I don’t know” is always a valid answer; we would rather you leave it blank than guess. The tools don’t diagnose faults, size equipment or certify that an installation is safe. They turn your answers into a plain planning result and tell you what we still need to find out.
See what a job like yours costs
Our heat pump cost estimator shows our typical range for a whole-home ducted job when your project fits it. We don’t price by the square foot or add a premium for your neighborhood. Electrical service changes, major duct work and hard access sit outside the range, and we price them from the site visit. If someone has already given you a written allowance for an extra item, you can enter it and see the math separately. Where you pick extra work with no allowance, we leave the upper total open. An honest open total is more useful to you than a tidy number that quietly assumes the extra work is free.
Find out what your house needs first
Our heat pump assessment asks ten questions about the property, the current system, the ducts, why you’re starting the project, comfort, keeping the furnace, the electrical side, permissions and timing. We built its results on simple rules you can read. A shared or uncertain system points to a scope review; an approval you don’t have yet points to building or board review first. Wanting to keep a good furnace can lead to a dual-fuel review, and an existing ducted heat pump leads toward replacement. The result doesn’t mean we’ve accepted the job or that the route is right for your house. It tells you what to gather before anyone picks equipment.
What the tools assume, and where they stop
You confirm the property is in DC before the estimator shows our range. If the address is outside the District, we don’t show local prices or rebate information. A house with no ducts, a commercial space, a shared building system or a single-component job doesn’t get the whole-home range. Your equipment preference and house size give us context; they don’t change the number. Neither tool takes a rebate off for you, and we don’t calculate a yearly running cost without your real bills and rates. Our cost guide and incentive guide explain what sits inside and outside the range. Your result is a planning aid built on your answers; we measure the house on the visit.
Bring your result when you ask for an estimate
Keep the result with what backs it up: model numbers you can read, building permissions you know about, a note on the rooms involved and any written allowance you already have. Don’t open equipment or electrical panels to answer a question you’re unsure of. Our survey preparation article explains what you can safely gather, and our quote checklist turns your result into questions for any estimate. When you’re ready, request an estimate with the property and what you want to change. Your timing tells us what you’d like; it doesn’t book a date or fix a finish date.
Share only your project choices
The estimator can make a link that carries your selected, non-personal choices, such as confirming the property is in DC, the project type and the access category. It never puts your name, phone, email, street address or message in that link. Any written allowance amounts you typed stay on your screen and stay out of the link. Check the choices before you share it, because anyone with the link can see them. Our privacy notice explains how we handle what you send through the inquiry form. Sharing a planning result is not the same as sending us a request.
Keep your answers with the result
A saved result is only as good as the answers behind it. If your project grows from a replacement into a conversion, or new access or electrical work turns up, run the tool again with the new answers. Don’t reuse an old upper amount once the work has grown. A written allowance from someone else is not the same as our typical range, and a technical question you couldn’t answer stays open even when the tool shows a category. Keep our project worksheet with any written estimates so you can line up the budget, the assessment and the final agreement side by side.
