Comparing Atlanta crawl-space duct-sealing quotes? Ask for a named HVAC system, a documented starting condition, the exact repairs, and a way to check the finished work. If the project also includes encapsulation, agree on the testing and installation sequence before either crew starts. A quote for a ground liner does not tell you what will happen to the ducts above it.
For Georgia Power customers, there is another practical checkpoint: the utility’s duct-sealing program has its own testing, installer and existing-space conditions. Confirm those with the program before counting on an incentive or changing the crawl space. This guide connects that local check to the questions worth asking both contractors.
First, define what “seal the crawl space” means
Ask each bidder to separate three kinds of work:
- Duct sealing: repairing the air-carrying system’s leaking joints, connections or damaged sections.
- Duct insulation: specifying the insulation and its outer covering around the ducts.
- Crawl-space work: controlling ground moisture, water entry and the surrounding environment, with an appropriate plan for the space.
These can belong in one project, but they are different deliverables. DOE’s metal-duct guidance distinguishes the sealed duct connections from insulation and its jacket. It also explains why sealing and insulation remain useful when ducts are within conditioned space. Ask for the assembly-specific details rather than assuming that encapsulation makes duct repairs unnecessary.
If the original complaint is wet ductwork, start with our duct-condensation guide. Water on a duct is a reason to investigate its source, not a complete duct-leakage test. UGA Extension’s moisture guidance identifies several possible contributors, including plumbing leaks, drainage problems and air-conditioning faults. A proposal should explain which observed problem its work addresses.
Check Georgia Power’s program before setting the work order
Georgia Power’s linked 2026 single-family requirements, effective August 1, describe duct repair and sealing for residential customers with most ducts in unconditioned space. They call for duct-system testing and a reduction of at least 30% in CFM25, or an equivalent measurement. A Program Installer or Duct and Envelope Tightness verifier may perform the improvement.
That makes a combined duct-and-encapsulation project worth discussing with the program in advance. Ask how it treats the existing crawl space, a planned conversion, and the order of measurements. Do not assume that either completing encapsulation first or simply calling the area “sealed” establishes eligibility.
The program page provides an installer finder and application guidance. Its displayed bundle amounts and the linked requirements were not fully aligned when checked on October 15, 2026. Confirm the applicable offer, deadline and paperwork directly; this guide does not quote a rebate amount or determine eligibility. An Atlanta address alone does not establish that the property’s electric service is with Georgia Power.
Request a starting record you can compare with the result
Before approving the scope, ask the evaluator to identify the system serving the affected rooms. In a house with multiple systems, “the ducts” is too vague. A useful report labels the air handler and the supply and return runs included in the inspection. Ask it to identify inaccessible sections as well.
ENERGY STAR’s contractor checklist recommends inspecting the whole duct system, evaluating supply and return balance, repairing damaged connections and checking airflow after repairs. Use that as a discussion framework, not evidence that a particular bidder has performed those checks.
For your project file, request:
- System identification: a label or photo that connects the report, quote and invoice to the same equipment.
- Observed defects: marked photos showing what needs repair and which findings remain uncertain.
- Measurements: the test name, method, units, date and result, with an explanation a homeowner can understand.
- Boundaries: whether the report covers one system or several, and which sections could not be reached.
- Retest plan: who will perform it, what it costs, and which records you will receive.
Ask the tester whether the before-and-after methods are comparable. A number without a system label or test description is hard to use when two contractors disagree. Also ask what happens if the crew finds damage that was hidden during the estimate: which work pauses, who documents it, and how you review a revised scope.
Put the two crews’ responsibilities on one page
A shared work-order sheet is useful even if one business coordinates the whole project. Fill in a company or person’s name beside each task. This is a planning aid, not a substitute for the actual agreements.
- Inspect and document. Identify water sources, duct condition, access limits and the proposed crawl-space design.
- Resolve the test sequence. Record who handles the initial duct measurements and any utility-program questions before work changes the space.
- Complete the identified repairs. Name who handles duct damage, insulation, plumbing or equipment issues, and crawl-space water management.
- Protect access and finished work. Agree how later trades reach the air handler and ducts without damaging the liner or blocking service areas.
- Check and hand over. Collect test results, photographs, operating instructions and the contact for unresolved findings.
For example, ask the encapsulation bidder whether its price includes moving any ducts or only working around them. Then ask the HVAC bidder whether the proposed duct route leaves room for liner seams and future maintenance. A sketch with a few labeled access points can expose conflicting assumptions before installation day.
Where fuel-burning equipment is present, name the professional responsible for evaluating combustion safety. ENERGY STAR specifically includes a combustion-safety test after duct sealing in its contractor guidance. Do not have a crew close appliance air openings merely because they look like unwanted gaps.
Compare the quote lines that change the actual job
Use the same questions for every bidder, and keep unanswered items visible rather than filling them in yourself:
- Repair or replacement? Which specific runs or components are included, and what finding supports replacing them?
- Included system? Does the price cover the identified supply and return system, or only accessible portions beneath the house?
- Insulation and covering? What materials, coverage and finished details will be provided? Ask the installer to explain requirements for this assembly.
- Other work? Are equipment service, drain repairs, removal of damaged material and crawl-space moisture work separately identified?
- Testing? Are the initial test, final test and written report separate charges or included?
- Completion? Who returns if a promised check cannot be completed that day, and when will the missing record be delivered?
Consider two hypothetical proposals. One includes duct repairs and documented testing. The other includes a liner and humidity-control equipment while leaving the HVAC system unchanged. Their totals do not compare like-for-like, even if both are presented as answers to the same crawl-space complaint. Request a common scope or an explanation of why the recommended work differs. The crawl-space quote-comparison guide offers a broader worksheet for that conversation.
Find the crawl-space side of the Atlanta project
Two existing directory profiles offer starting points for discussing the surrounding crawl-space work:
- Atlanta Crawl Space: its company site lists encapsulation, insulation and drainage or waterproofing services. Ask which of those are supported by your inspection and who handles any separate duct testing.
- Crawlspaces and More: its company site describes metro Atlanta encapsulation and waterproofing work. Ask how its proposed installation coordinates with an HVAC visit and preserves equipment access.
These are service-scope examples, not a ranking or confirmation of HVAC qualifications, utility-program participation or availability. Confirm your address and exact work directly. You can also browse the Atlanta contractor archive. Use Georgia Power’s own installer finder for program participation checks.
Frequently asked questions
Does a crawl-space quote automatically include duct sealing?
No. Ask for the duct work and its verification to be written into the scope. Photos of a completed liner show the liner; they do not document the condition of every duct connection.
Should duct work happen before encapsulation?
Agree on a project-specific sequence after the initial inspection. Access, needed repairs and any program testing can affect the order. Have both crews acknowledge the plan rather than relying on a verbal assumption.
Will a successful leakage test prove that wet ducts are fixed?
It answers the question covered by that test. If moisture was part of the complaint, ask for a separate follow-up on the identified water source and affected materials. Keep those results alongside the duct report.
What should I keep after the job?
Save the agreed scope, identified system, before-and-after reports, repair photos, invoice and maintenance instructions. Record any excluded areas or unfinished checks so the next service visit starts with the same information.
