"Mamayek Heating was very proficient with their installation of whole house central air-conditioning in our 1896 year-old home which never had a unit in place. From start to finish, they accommodated our needs and schedule as well as leaving behind a nicely done project in working order. Thank you to the 3 Bobs for all their help!"

"Swimmingly. I interviewed quite a number of HVAC companies for this job by sending out an RPF (Request for Proposal), and Bob Mamayek was unquestionably the most thorough in his on-site evaluation. Installation crew was fantastic. This is a small shop, and it was a true pleasure to have a team of regular guys just getting the job done. I recommend them without reservation. I almost gave them a B for responsiveness because Bob doesn't do a lot of email, but I realized while typing that this would be completely unfair, for two reasons. A) Bob might not respond to email with email, but he did always respond with a phone call. Frankly, that is better on many counts. B) This ignores the amazing response to my RPF, which was both timely and thorough. So, really, this says more about my email-centric life than Mamayek's responsiveness."

"One Hour Heating & Conditioning was prompt arriving at the scheduled appointment time. My wife and I also appreciated receiving a message that the techs were on their way. Our techs Kyle and Jacob were friendly, professional, and knowledgeable. Arguably one of the most thorough annual checkups I have had since being in the home for 7 years and using some other services in the past. While both furnaces are well beyond their expected life, neither tried to "oversell" me and offered objective pros/cons to some repair options vs. replacement. I would highly recommend One Hour Heating & Conditioning."

"Customer service was excellent. Everyone from the person who first answered the phone to the guys who did the cleaning were friendly, professional, courteous, and thorough. We can tell the difference in the air quality already and our furnace sounds quieter too."

"Shane was able to schedule a prompt appointment. He arrived on time and performed a thorough diagnostic on the furnace. He identified an issue I was unaware of and corrected the problem with the air conditioner using parts that were still under warranty. I will gladly use his services 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.
