"A great experience from a terrific team. After we were told by our (now past) HVAC company that we needed a new furnace, I called Design by Comfort for a second opinion. When I called their office, the woman I spoke to understood my situation immediately and had their team on my doorstep at 8:00 the next morning, on the dot as scheduled. Their service specialist took apart the furnace inspected it and showed me by video the heat exchanger that our original contractor told me was bad.
Based on his very thorough examination, we knew that the furnace did not need replacement.
Obviously, the first company did not tell us the truth about the condition of our furnace so as to sell us a new one even though it was not needed.
The Design by Comfort team was honest, professional, and highly responsive. They saved me thousands of dollars. When the time comes, and it always does, for us to get a new furnace, they will certainly get our business.

"Riley was the technician who serviced my air conditioner yesterday. Riley always kept me informed on the progress of the work he was doing and before leaving THOROUGHLY explained the condition of my air conditioner and what I can do to extend its life. Fortunately my air conditioner, even though it’s 11 years old, is in great condition and I plan on doing things to prolong its life. Overall I would give Riley a rating of 10. He is an exceptional technician, knows his job, explains things well, and personable. The cost today was $17 for a replacement filter."

"They retrofit a central air conditioner in our 1920s house with radiant heat (no existing duct work) and it looks great. It is February so the AC canâ  t be run yet, but I expect it to work great. They worked quickly and left with the house just as clean as when they arrived! Thank you Hero!"

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.
