"Our AC went out yesterday evening and this morning at 7:30am my sister called an AC repairmen, Legacy Air Heating & Cooling, they answered the phone right away, made the appt for 10-12 today! Repairman showed up on time, fixed the clogged drain, checked the unit over, and told us a price, then finished fixing the problem, unit was low on freon, and then went into the attic to see if any ductwork was loose or off of the ceiling vents. Josh is a very professional serviceman. Best AC Repair experience I have ever had!"

"I had been experiencing uneven heating and cooling and high electrical bills for many years. My unit was also almost 20 yrs old and not working very well anymore. I did my homework and decided I wanted a Trane. I contacted several companies for estimates. Air Network as the only company who contacted me in the time frame promised as well as coming out to see what my needs really were. It turned out my duct work was done improperly by the previous owner resulting in my uneven cooling. Air Network answered all my questions honestly and gave me several bids on different brands and sizes before the day was done. I still insisted on the Trane which by brand names is not the least expensive but was still at a very good price. His crew showed up on time during a day where it rained all day. They put mats on my floors and began dismantling my system. Chris the owner drove 2 hours to north Austin to pick up the unit I requested since there were no local Trane outlets and then 2 hours back to Hallettsville. They worked so efficiently I actually fell asleep in my recliner while they worked. By the end of the day I was more comfortable in my home than at anytime since I bought it. His crew were neat and courteous and left my home cleaner than when they arrived. I was so impressed by Air Networks that I will not allow any other company to service my system in the future. There were no extra or hidden costs. The job was done for exactly what the estimate was. I HIGHLY recommend Air Network. This is the first 5 star rating I've ever given a business, but Air Network truly deserves it."

"Excellent job! When our AC went down, the owner Donny came out the next day, arrived on time and replaced the entire unit. He was professional and considerate. We have built 2 houses so have dealt with a lot of contractors..I’m usually mad by the end of the job..but couldn’t be happier with Wolfe City Heating & Air! We found our guy!"

"The technician that fixed my air conditioning unit was very professional and informative he answered all my questions and knew what he was talking about I would definitely want this technician back to my house to work on any of my issues on my air conditioning unit"
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.
