EXISTING HOME – TESTING SERVICES
If you have an existing home, these testing services may apply:

Combustion Appliance Safety Testing:
The focus of this testing is to find out whether an appliance is creating unacceptable levels of carbon monoxide and whether it can spill into your home.

Carbon Monoxide:
This test looks at how much carbon monoxide is being created by heating appliances and how much is in the air of your home.

Spill/Draft – Worst Case Depressurization:
These tests evaluate the risk of combustion gases getting pulled back down into your home from the chimney(s) because of large negative air pressures. The testing finds out why the negative air pressures are created and the test data helps in designing a system that will work.

Cracked Heat Exchanger Testing:
Furnace heat exchangers should be airtight and only let heat through. This test checks for the ability of combustion gases to leak into the air that the occupants breathe.

Building Shell & Air Leakage Testing:
After the combustion safety of the occupants, this is the primary focus of a whole house assessment because leaking air is at the heart of most building performance issues. Stopping air from leaking has been the single most neglected component of upgrades, rehabs, and the building of new homes.

Blower Door Testing/Air Changes Per Hour:
This test measures the air leakage rate of your home. How often does the air change in your home? This test includes locating the large hidden holes that need air sealing. These holes allow unintentional air leakage either to or from our homes to attics, floors, walls, and garages, which typically has a huge impact on building performance problems.

Rating:
A Rating provides an “Improvement Analysis,” a computerized savings vs. investment analysis that helps you decide which energy conservation measures are the most cost effective.

Multi-zonal Pressure Diagnostics:
This test determines what portion of building shell leakage is associated with adjacent unconditioned spaces (i.e. attics, garage, three season rooms, crawl spaces, etc.). The data collected is used to verify whether the work specified in the scope of work was completed successfully.

Infrared Camera:
This inspection can visually show missing insulation and air leakage pathways.

Indoor Air Ventilation & Moisture Source Analysis:
Controlling airflow in and out of the home can help eliminate air quality problems.

Fan Flow Testing & Design Assessment:
Flows are measured and balanced by design while considering the whole house.

Locate Moisture Sources:
Identify areas and offer remedies about how to control moisture buildup that contributes to mold growth. Measure relative humidity of various areas of the home.

Air Distribution System Testing:
The lack of air movement through the furnace’s distribution system can significantly affect the comfort and efficiency of your heating and/or cooling system.

Furnace Air Duct Leakage:
This test measures the air leakage rate of the ductwork of your home’s heating system.

Furnace Air Flow Balancing:
This test is designed to balance the air moving through the furnace duct system to the various locations in the house.


NEW HOME – SITE VISITS, CONSULTATION, & TESTING SERVICES
If you’re building a new house, these testing services may apply:

I. Plan Consultation:
Assesses the proposed home while considering how to enhance the design to achieve a high performance structure.

Building Science Consultation:
How will air leakage flow, heat flow, and moisture flow happen with the current design and be best changed to enhance this home design?

Mechanical Consultation (Ventilation & Electric Efficiency):
How can Indoor Air Quality and Electrical Efficiency best be achieved with the major mechanical systems in the house?

Home Energy Rating System (HERS):
A computer analysis of the energy efficiency of the structure (based on plans) offers code compliant heating and cooling calculations which help you decide what size equipment will keep your home comfortable.

Radon Consultation:
Radon in the ground can not be checked before the house is built. What cost effective changes can be made with the design so that, if found in the house post construction, it can be remedied with a minimum cost?

I
I. Site Visits & Continued Consultation:
Footings, foundation, windows, roof flashing

Moisture Flow – Footings, foundation, windows and doors, roof flashing:
These field site visits make sure that the below-grade drainage plane, the above-grade rain screen, the window and door flashings, and the roof flashing are installed as specified.

Air Flow & Sealing – After framing/rough-ins are complete:
These field site visits during construction make sure that all building shell air leakage areas are sealed. Uncontrolled airflow in and out of the home through the shell can be the cause of comfort, durability, air quality, and energy efficiency problems.

Heat Flow and Thermal shell – During insulation installation:
These field site visits during construction make sure that insulation is installed with no gaps, voids, misalignments, or compressions.

III. Site Visit: Post-construction Testing:

Combustion Safety Testing:
This test identifies how much carbon monoxide is being created by heating appliances and evaluates the risk of combustion gases getting pulled back down the chimney into your home because of large negative air pressures. The test data analysis allows for the determination of why the negative air pressures are created and helps in designing the lowest cost remedy that will work.

Blower Door Testing:
This test measures the air leakage rate of your home and how often the air changes in your home. This information is important for fan design with reference to air changes of the home.

Fan Flow / Ventilation Air Measuring:
Flows are designed and measured for the whole house.

Heat & Cooling Air Distribution Testing:
These tests either measure the air leakage rate of the ductwork or help in balancing the air moving through the furnace duct system, or both.


NEW HOME – PROBLEMS WITH NEWLY-CONSTRUCTED HOMES
If you’re experiencing problems in a newly-constructed house, then these tests may apply:

Site visit: Newly Constructed House Diagnostic Testing

Combustion Safety Testing:
This test identifies how much carbon monoxide is being created by heating appliances and evaluates the risk of combustion gases getting pulled back down the chimney into your home because of large negative air pressures. The test data analysis allows for the determination of why the negative air pressures are created and helps in designing the lowest cost remedy that will work.

Mold – Finding the Source of the Moisture:
Identify areas and offer remedies about how to control moisture buildup and the start of mold growth. Measure moisture in materials and relative humidity in various areas of the home.

Multi-zonal Air Leakage Diagnostic Measuring:
This test includes locating large hidden holes that need air sealing. These holes allow unintentional air leakage either to or from our homes to attics, floors, walls, and garages, which typically have a huge impact on building performance problems such as comfort, durability, indoor air quality, and energy efficiency.

Air Handler (Dominant Door) Pressure Testing:
This test can be helpful in analyzing the need for further Furnace Air Flow measuring.

Furnace Air Flow Testing (Balancing):
This test evaluates the ductwork design and how well air is moving through the furnace duct system. The lack of air movement through your furnace can significantly affect the comfort and efficiency of your heating and/or cooling system.

Forced Air Duct Leakage Testing:
This test measures the air leakage rate of the ductwork of your home’s heating system. If ductwork runs through unconditioned areas of the building it is important to know that air is not leaking into or out of the ductwork. Solving these problems will affect the comfort, durability, indoor air quality, and energy efficiency of the home.

Infrared Camera:
This inspection can visually show missing insulation and air leakage pathways. It is a cost effective tool because it allows for immediate feedback as to the location of these problems.
