"They installed a new boiler and central air conditioning in my DC rowhome and did a fantastic job. Joe answered all of my questions and they stayed on schedule with the project which was great because it was a larger project. I would highly recommend their services for the quality of workmanship and their prices were very reasonable as well. I will contact them again for future HVAC work in the DC area."

"Quickly diagnosed the central air conditioning system, and gave an estimate on the cost of recharging the refrigerant in the compressor. The system is a 14 year old Carrier unit. Albert also included some sealant that may plug up the slow leak of refrigerant that occurs every 2 years or so. Albert also, showed me how to adjust the damper to control the flow of air to the second and third floors of the house. The other company that arrived wanted to charge me $5,000 to repair the system or close to $7,000 to replace the AC system with new. I intend to call upon Magna Tech Temp Air, Inc when I'm ready to purchase a new HVAC system. Thanks again for taking the time to listen to my concerns. Well done!!!"

"This was for semiannual maintenance under contract. Danny performed an excellent job, he has many years of experience. I have used ARS for the heating/air conditioning maintenance for about 35 years. They replaced the equipment about six years ago. It has not failed since replacement."

"I have been a customer for a very long time and this scheduled maintenance and dryer vent cleaning was done by Cesar. I have to say he is one very thorough technician and I was very pleased with his inspection and vent cleaning. His service was so different than some of the ones I've had before. I even had one inspector tell me he didn't need to check in my attic which houses one of our two units. Let me tell you about Cesar, he even cleaned up behind my dryer for me. This is something that is rare in customer service. I have my HVAC seasonally maintenanced and never had a inspector be as thorough as him. The pictures he took and explained to me and the one problem he found that no other inspector had found in all this time. I tried to spare him from the attic heat for the repair and have him return on another day in the morning but he didn't mind going back in there to fix the problem for us although it was in the dead heat of the day. I just hope the company sees this review and knows what a good technician they have in Cesar."

"Terrific all around. Our air conditioning went out on Memorial Day weekend and Joe came out early in the morning on Sunday and diagnosed a simple thermostat issue. He fixed it and charged a very reasonable fee. He also provided solid professional advice regarding our aging HVAC system. We will definitely be calling him to replace the whole system in the near future. Highly recommend."

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.
