"Dave did a great job, he explained what caused our Heat pump to stop working. We bought this unit last June 2019 . So we were very upset when the unit stopped working, it was so hot and Dave had to go up into our attic / crawl space. That was super hot, but he was able to find the problem and get our unit to work. We are very thankful for having Dave as our technician. Thank you Dave and Rohrer's One Hour Heating and Air Conditioning. We have been with them for 35 years."

"When I turned my A/C on for the season, the system wasn?t cooling. I had a tech come out and I was told that the system had a leak. Because the age of my system, I decided to replace it with a new one. The team at Green Air Concepts were prompt, neat, and they were very nice people. They did an amazing job, and my house is now cooling beautifully."

"They were absolutely wonderful. They are great people to deal with. It's a husband and wife company and they've just hired two new people. Everybody is well trained. They are very good. I have a gas heater and they even put a humidifier on it. They give you a quote before they do any work. They answer all your questions and explain the contract. I ran into them in a grocery store and they immediately recognized me; they are very personable."

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.
