Blower Door Tests Usually Cost A Few Hundred Dollars.

The exact cost of a blower door test will vary by technician. Few companies seem to offer transparent pricing on their websites. Those with pricing available may charge as low as $250, but there may be additional travel fees.

At South Central Services, we charge between $300 and $500 for a blower door test.

A Blower Door Test May Be Part Of A Larger Home Energy Audit.

As you request quotes from certified blower door technicians, you may find the prices to be much higher. In these cases, you may be inquiring about a home energy audit.

A home energy audit is more comprehensive than a blower door test alone. In these audits, a blower door test is one of many pieces of the inspection. You will likely pay more if you opt for a more extensive audit.

A detailed home energy audit could cost between $600 and $900, including thermal imaging and advanced diagnostic tests.

Why Do Professionals Charge That Much For Blower Door Tests?

Does $500 feel like a lot for your blower door test? Let's examine some of the factors that influence the price of blower door testing.

1. The Price Includes Travel Costs To Your Home Or Building.

At South Central Services, the cost of your blower door test includes travel. Other technicians may charge additional fees for travel.

Transporting both the technician and equipment to your job site requires gasoline and the use of a vehicle.

2. The Price Helps Cover The Cost Of Specialized Equipment.

Blower door testing must be performed with carefully calibrated equipment. Technicians maintain this equipment, but the equipment sometimes needs to be replaced.

3. The Price Accounts For The Technician's Time.

While blower door testing can easily be accomplished in a morning or afternoon, you will pay for the technician's time through the price of the test.

Should I Invest In A Blower Door Test?

If you're building a new home, you likely need to invest in a blower door test. This testing is required by the International Energy Conservation Code (IECC) in most areas. Once your home is essentially completed, one of the final steps is passing a blower door test.

If you're living in an older home, you may want to consider a blower door test. Blower door tests quantify the air leakage and pinpoint where air is leaking from. While $500 may feel expensive for a diagnostic test, you'll know better where to start with energy efficiency upgrades afterward.

If you have the budget for insulation or HVAC upgrades, it's best to know which upgrade will deliver the most improvements to your energy costs and comfort.

The Bottom Line About How Much Blower Door Testing Costs

Blower door tests can cost anywhere between $250 and $500. Some companies may charge additional fees for travel. Blower door tests can also be a part of a home energy audit package. Home energy audits can be more expensive than a blower door test alone.
