Measured Performance Testing

How Comfortable Are You (in your home)?

- Are your energy bills higher than your neighbors?
- Is your home just not comfortable? ?Cool in the winter? ?Warm in the summer?
- Is your indoor air quality less than you would like it to be?
- Could it be that there is nothing wrong with your heating and AC system?
- Do you know that a heating and air conditioning system replacement is imminent?

In the past, air leaks have been ignored unless they were significant enough to feel or see. ?Building scientists have had the tools for assessing air leaks for years, but how many building scientists do you know? ?I predict that since our building codes are getting tighter and the cost of energy will continue to increase, the tools for accessing air leakage will become more prevalent. ?I obtained the tools because I think I can significantly improve the service that we offer. ?I think consumers are unaware of how much they could benefit if someone utilized the tools to identify and quantify the amount of air leakage that is occurring in their homes.

The benefits that you should expect from air leakage testing implementation of improvement measures are:
1. ?KNOWING where the opportunities ?exist for improvement and which ones to attack first.
2. ?Significantly (and possibly, surprisingly) REDUCED ENERGY COST
3. ?Greatly improved COMFORT
4. ?Greatly improved AIR QUALITY
5. ?Minimization of SOUND LEVELS inside your home.?

The quantified results of performance testing remove the mystery of discomfort and high energy bills from an evaluation. ?A benefit assessment of the recommended measures helps you rank the order in which measures should be pursued. ?If you were to receive a strategic plan that provides the peace of mind of ranking the measures that provide the most benefit to you, wouldn?t that be valuable? ?Because I am a heating and air conditioning contractor with many years of experience in energy conservation issues from previous employment with an electric utility, I feel that I am qualified to provide this service. ?And yes, my primary interest is in issues that impact indoor air quality and heating and air conditioning systems.

We can perform a test on your duct system to measure how much duct leakage is occurring.? Did you note that we didn?t say ?IF your duct system is leaking??

All duct systems leak.? The new energy code for new homes that is now in effect (in NC) limits duct leakage to a total of 6% of total air flow.? And the only way to achieve such a low leak rate is to test the duct system immediately after construction and seal the leaks.? If you are not aware that your duct system has been tested?expect at least a 20-30% leak rate, even if you have a newly constructed duct system!?? It is highly probable that 20 ? 30% of the air you are paying to condition (heat or cool) is being wasted in ?outside spaces? ? the attic or the crawl space.? I think it?s evident that sealing duct leaks would be an opportunity for significant energy cost reduction.? We can measure the performance of your duct system (called a ?duct blaster? test) and make the corrections to improve the performance of duct systems.? And we will continue re-testing after corrections are performed so that we will achieve a satisfactory duct leakage rate is (hopefully 10% or less).? Our goal is to reduce duct leaks without?unnecessarily?replacing your existing duct system. ?And it seems to me that if you were considering the replacement of a heating and air conditioning system, having the duct system tested would be required before a replacement occurred!

A blower door provides the capability to measure how much air from outside your home is entering from undesired areas.? If the door(s) are not open and the windows are closed, outside air entering from the crawl space, garage, or attic could be the sources of concern.? These types of sources are identified as unwanted infiltration.? Don?t get me wrong, for air quality reasons houses need to breathe and some infiltration is a good thing, as long as it is not excessive and is not entering from contaminated spaces like attics, crawl spaces, or garages.? Do you suspect that you live in a house that is not constructed as tightly as it could be?? A whole house, measured, air leakage test is known as a ?blower door? test and can be very revealing when the amount of air entering you home is measured and then compared to the amount of air entering a well-constructed home.? And there are ways to determine where leaks (if they do exist) occur.? And we will show you where they exist.? I encourage you to think about how these reductions would impact your energy bills, improve indoor air quality, and make your home a quieter place to live in if those leaks were prevented.

If you have read this far, I think it?s fair to assume you ARE interested in this service. ?If you should call another heating and air conditioning contractor for heating and AC service, ask ?if air leak testing is provided and if provided, what tools are used to provide the service.
? If you do not hear ?Blower Door? or ?Duct Blaster?, they are not equipped to provide the service.
? If you hear ?Duct Blaster? only, they can only test for duct leaks.
? If you hear ?Blower Door? only, they can only provide an estimate of duct leakage. ?Only with a ?Duct Blaster? can identification of air leaks be properly identified.

I think it will be unlikely that you find a heating and air conditioning contractor that provides the service that we can. ?Of course you could call a building scientist, if you know one?Calling to receive this service after you come home for work is OK with us (DARK air can be measured too). ?Call us at 910-5749-8866. ?We pledge to present test results that would comply with Jack Webb?s (of the Dragnet TV show from years gone by) criteria ? ?Just the Facts?.
