"Fabulous service. The employee who checked our air conditioner was personable and knowledgeable. He replaced a small part, cleaned both of our air conditioners and now the noise that one of them was making is gone. We were pleasantly surprised by his friendly manner and we felt him to be extremely trustworthy which is a rarity these days."

"Always stayed in contact by phone before, during, and after install. They worked until after dark because we had no heat during this unusually cold spell. Salesman Chris stopped by during install."

"The installer found that we needed another part, other than just the compressor, that he didn't have (this was for an air-conditioning unit and we live in Arizona so its vital to have this work) so he called around until he found one then drove to pick it up and stayed late to be sure we had a working unit before he left. Also, Clayda is an associate who I dealt with at Mechanical Brothers and she too was amazing! I highly recommend Mechanical Brothers!!"

"Arrived within 2 hours of my desperate plea for help, my ac was blowing HOT air. He found a wire burnt from it being loose. He explained that today's service call and diagnostic time would be about 290 dollars ( Sunday afternoon) He explained to me that his company offers a maintenance thing where he checks and cleans my unit twice a year. I bought the maintenance plan and he didn't charge me a Nicole for a service on a Sunday. Call him and you can fix tour ac before it stops working"

A standard blower door test takes between 30 minutes and one hour to complete. The process involves setting up specialized equipment in your doorway, running the fan to create pressure differences, and taking measurements throughout your home. Additional services like thermal imaging or detailed leak detection will extend this timeframe. The technician will also spend time explaining the results and making recommendations based on their findings.
Preparation involves turning off all combustion appliances, such as gas furnaces and water heaters, for safety. Secure all exterior doors and windows, but leave interior doors open to allow airflow throughout the house. Close fireplace dampers and cover any ashes to prevent them from being drawn into living spaces. Clear access to potential inspection areas like attics and crawlspaces, and inform everyone in the household about the test to prevent accidental door openings during the process.
Older homes often benefit most from blower door testing because they have more air leakage points than newer construction. The test can pinpoint specific areas where relatively inexpensive improvements will yield significant energy savings.
Many homeowners of vintage properties report noticeable reductions in drafts and more consistent indoor temperatures after addressing issues identified during testing. The potential utility savings often recover the testing cost within a reasonable timeframe.
New construction must meet increasingly stringent energy codes that specify maximum allowable air leakage rates. Meeting these standards requires careful attention to air sealing details during construction.
Success depends largely on properly installing air barriers, thoroughly sealing around penetrations, and quality control throughout the building process. While achieving code compliance is challenging, builders who implement systematic air sealing protocols succeed in meeting required standards.
It's best to schedule a follow-up test after completing all recommended air sealing and insulation work. This allows you to verify the effectiveness of your improvements as a complete package. Allow sufficient time for all sealing materials to cure properly—often a few weeks after completion. The verification test provides documentation of your home's improved performance and confirms you've addressed the issues identified in the initial assessment.
