"We have been waiting for a call back for over 2 weeks. We had a 4k job to ground our above round pool a month ago. We need the inspection certificate to pass the village inspection. It failed after the first try so the company sent someone else to fix the issue in order to be complaint with our village. We waited from 12p-9p for someone to show up. We received a call late that night that they couldn't come and would come the following day. The electrician finally came 7 days ago. He "fixed the issue". He stated we would receive the inspection shortly. The inspection company just "needed a picture" of the change to approve it. My husband has called Universe several times. Left several messages for the DOO with no response. He just got off the phone with a "Chris S" who says he is a project coordinator. He argued with my husband stating, "we are at the mercy of the inspection company". Universe chose this inspection company! We paid for it! Our village inspector is coming tomorrow (appointment made three weeks ago thinking this would be resolved) and we still have no electrical inspection. My husband had surgery Monday and is supposed to be healing. I NEVER write bad reviews..i try to resolve first but I have nowhere else to go. All I need is the inspection certificate! My next step will be to stop payment. UGH..what is so difficult here?"

FAQs for air conditioning projects in Wantagh, NY

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.
