Dedicated Home Energy Audits & Insulation Contractors in Fairfax County, VA

Our patented product, Tight 'N True duct encapsulation system, provides airtight insulation coverage. It provides extra sealing to the existing duct wrap, delivering airtight protection and heat resistance. It enhances the effects of your insulation, optimizes your energy usage, and lowers utility bills. 

Some benefits of duct encapsulation include: 

- Superior R-value per inch

- Recovers insulation value from existing duct insulation

- Highly efficient with performance enhancing add-ons

To maximize the insulation performance, the Tight 'N True system can be combined with our TruSoft blown-in cellulose insulation. The cellulose insulation heavily guards and covers the ducts, resulting in even more energy-saving and home performance capabilities. 

A radiant barrier should always be a part of a home's insulation system. It functions to reduce temperatures in the attic by reflecting heat away. Radiant barriers are installed around the joists, roof beams, and wall studs - when combined with other insulation services, your attic can become a conditioned space. 

Besides comfort, installing a radiant barrier can allow you to use your attic for storage, because the heat will no longer damage your belongings. Radiant barriers can lower attic temperatures by up to 30 degrees. An insulated attic will also keep humidity lower, preventing moisture or mold damage to your things as well.

I just wanted to let you know that the work that was done in my house made a WORLD of difference!!!  My upstairs bedroom is perfectly comfortable now – the heat comes blasting out of the vent.  The main floor is also more comfortable in the front room (over the storage room that had the exposed floor). Overall, the temperature is very even throughout the home.  I think that duct cleaning and sealing may have been the key to making this change.  While the insulation needed to be done (for sure), the vents upstairs now blow air much more strongly. Also, adding the return register and sound-lining the return ducts cut down on the noise. I don’t even notice the heat when it’s on.  I am waiting to see how things sound with the AC – that was always a lot noisier.

Just wanted you to know!

Thanks for everything,

This Herndon VA homeowner was experiencing home comfort issues due to having different rooms in their home have different temperatures year round.  they call Comfenergy to ask for a home performance inspection.  Our sales professional Jason went out to visit and performed a free whole home assessment.  He was able to find the issue causing the comfort issues but while speaking to the homeowners they also mentioned that their home was very noisy and that they were interested in finding a way to reduce the sound that travelled through the home in hopes to have a much quieter nursery room.  Jason was able to offer our wall dense packing solution using Rock Wool insulation.  This would not only help to reduce the sound in and around the home but it would also serve to better insulate each room that was treated.   Dense packing involves cutting strategic locations in the drywall and then filling the space inside of the wall from top to bottom with Rock Wool insulation.  This is a fire safe material that greatly reduces the ability for noise and sound to travel through the walls of the home.  This home will now be quieter, more energy efficient and most of all, more comfortable.  

This Springfield VA home had comfort issues that were bothering the homeowners.  The top floor of the home was too hot i the summer and the air inside the home felt humid.  The homeowners called Comfenergy asking for help and had our Home Performance Sales Expert Eric come out to do a no cost inspection.  Eric checked the home from top to bottom and found out what was leading to the problems.  Eric identified an insufficient amount of insulation in the attic and a lack of an air seal for the space.  This meant that conditioned air from the HVAC system was not able to stay in the rooms it was being pumped into because it was able to escape via light fixtures, air vents and cracks or gaps in the structure of the home and drywall.  Additionally Eric noticed that several bathroom exhaust ducts had become disconnected and were venting air directly into the attic, rather than out of the home.  An HVAC duct was also found to have a loose joint where the set up turned and was leaking conditioned air.  This all made the HVAC less effective and added humidity to the uncontrolled attic air.  Our Production Team started the project by removing all of the old insulation in the attic, then used Zyp Foam to seal up the cracks, light fixtures and vent edges making a better air seal for the space.  They reset the loose ducts and replaced several of them with insulated new material that would better serve to deliver vented air where it needed to go.
