The service
What home energy audit is, what a visit covers and where the line is.
The short answer
A home energy audit is a walkthrough by a trained pro who looks at how the building holds heat and cool air. Home Energy Audit in Los Altos Hills is booked through pros who cover its 1 ZIP codes, in neighborhoods such as Fremont Hills, Country Club, and Page Mill. In Los Altos Hills, the dry season from late spring to fall is the easiest time for outside work, and the fall calendar fills before the first big rain. The audit identifies and ranks problems and does not do the fixes.
What a home energy audit visit includes
What is included depends on the jobs you pick and on how each pro sets up their visit and timing. You see the exact scope with each pro's price before you book.
- Whole-home walkthrough

What shapes a home energy audit job
These are the things that make one job different from another. Mention them in your notes so each pro can scope your job properly.
What you receive
A home energy audit normally ends with a written report and a prioritized list of improvements. Each pro sets what they provide, including which tests are part of the visit.
- A written summary of the building shell, insulation, windows, ducts and equipment
- Thermal images that show heat loss and missing insulation, where the pro takes them
- Air leakage results, if a blower door or similar test is part of the visit
- A ranked list of improvements, with general notes on expected benefit
- Safety notes on combustion appliances, ventilation or moisture seen during the visit
- Suggestions on who to hire for each improvement, without doing the work
What is not part of home energy audit
Knowing where the line is keeps the visit on track and keeps you safe. When a job belongs to a specialist, NorTech tells you before you book.
- Installing insulation, sealing air leaks, replacing windows or repairing ducts. Those are separate services for the right pro.
- HVAC replacement or refrigerant work, and electrical upgrades. Pros who hold the matching license do that regulated trade work.
- Any job where labor and materials together reach $1,000. A licensed contractor takes that work on, and you are told before you book.
- Guaranteed savings on your bills. Estimates are informed but depend on usage, weather and how upgrades are done.
- Permit applications, rebate paperwork or program enrollment, unless the pro offers it.
- Opening walls or ceilings to see inside. The auditor reports what is visible and what imaging shows.

Before you book home energy audit
Quick things that save a trip. Tick them off as you go; none of it is required to book.
Collect your recent energy bills
Gather 12 months of electric and gas bills, or download them from your utility. Seeing winter and summer use side by side helps the auditor check the findings against real consumption.
List the rooms that feel wrong
Note rooms that are too hot, too cold, drafty or stuffy, and when it happens. Comfort complaints point the auditor straight to problems like missing insulation or duct leaks.
Clear access to attic and utility areas
Make sure the attic hatch, crawlspace door, furnace closet and water heater can be reached. Move stored items away from walls and ceilings the auditor needs to scan.
Keep the house at a normal temperature
Run heating or cooling as you normally do on the day before and the day of the audit. Thermal imaging is easier to read when there is a steady temperature difference across the walls.
Photograph problems you have noticed
Take pictures of frost on windows, ice at the roof edge, drafty outlets or damp spots, with the date. They give the auditor clues that may not show during the visit.
Ask what tests are included
Thermal imaging, a blower door test and duct testing are not always part of the base visit. Ask each pro what they offer so quotes compare equal scopes.
Say where in Los Altos Hills you are
Add your neighborhood, for example Fremont Hills, Country Club, and Page Mill, or your ZIP code to your notes. Pros choose the neighborhoods they cover, and it tells them how far they have to travel.

Best time to book home energy audit
