Q: How much should I expect to pay for a home blower door test?

Blower door test cost

Blower door test is a method used by professional energy auditors and raters to measure a building’s “air tightness”. This test is a proven way to identify air leaks to and from your house through floors, walls, ceilings, windows and doors. A typical blower door test will take 1.5 – 2 hours to complete.

Blower doors come in a calibrated or uncalibrated variety. Make sure that your energy auditor uses a calibrated blower door as this type of blower door can allow the auditor to quantify the amount of air leakage and thus estimate the success of the air-sealing job.

Expect to pay anywhere between $175 to a couple hundreds of dollars for a home blower door test. There are several factors that the actual cost will depend on such as the complexity and size of your home. Sometimes,  factors such as distance to your home and perceived travel time are factored in too.

Some companies may lower the rate if you are a regular customer.
