"I contacted Greg after I turned on the heater for the first time and noticed a burning smell coming from the ducts. While they were booked out three days in the future, Greg found a way to work us into the schedule the same day. Within hours, they had the problem diagnosed and had located the parts needed to fix it--all at a fair and reasonable cost. Additionally, they offered advice on how best to maintain our air conditioning unit. I would highly recommend them and will be calling them again with future work."

"As female investor seeking to hiring contractors that are transparent and have high integrity. I hit the jackpot with MIDPOINT COOL TEMP. Robert is passionate and genuine in his assessment and recommends "options to repair" vs immediately replacing a unit. Provided him a key to the vacant home, he got the heating system functioning, cleaned his area, and updated us promptly. FIVE STAR SERVICE all around!!"

"Zack came in to give me quote as was the only guy who was not a sales person. Value for money wise his company is excellent. He installed Tempstar furnace and Media filter. We pulled the permit . The mechanical inspector came in and said whoever did this job did it professional. Particularly he liked how the media filter cabinet was installed. We couldn't get the CWire to the thermostat. He will be coming in this week to install it. Every electrical connection were clamped to the duct properly. He also put in new drain for the humidifier. Awesome guy. Normally I would wait for atleast 6 months to a year to leave a review. In this case, because of the exceptional installation and because of the comment that inspector made i am leaving 5 star review. Will update in future if any new issues crop up. I don't expect that to be case."

"This company went above and beyond. From the estimate to the install of both a new furnace and air conditioning unit quickly after the estimate. We had been without heat for 4 days in December in Michigan. Glad to sleep in a home with heat again."
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.
