Home Energy Essentials’ Home Performance and Efficiency Testing will show you where your utility dollars go each month. Improvements made to a home comfort system can be measured again after alterations are completed to validate the increased efficiency.
Testing your duct system for leaks will determine if duct sealing needs to be performed or if a new duct system should be installed. On average a duct system over 10 years old leaks 35% of the total available conditioned air moving through a house. Duct leakage standards are 5% or less for new ducts and no more than 15% total duct leakage allowed for existing ducts
Airflow / Fan Watt Draw
Airflow is everything in terms of air conditioning. Manufacturers design their systems to deliver 400 CFM per ton of air conditioning. Your HVAC system is losing efficiency If your air filter is too restrictive, or there is inadequate ducting to handle the size of HVAC system you have. By measuring system airflow we can determine how much air we have to heat or cool your home.
The Fan Watt Draw measurement tells us how efficiently the main circulating blower is running, electrically speaking.
Air Conditioning systems are a closed loop system. The refrigerant charge is application specific. Refrigerant line sets vary in size and length, requiring adjustments over, or under the manufacturers factory charge. Every Air Conditioner should have the correct refrigerant charge in order to deliver the designed cooling capacity and to protect the compressor.
An over charged A/C is going to have higher operating pressures, will be louder and less efficient than a properly charged system. A system that is under charged can have the same effect on the equipment, plus not cool properly in extreme heat.
Our Refrigerant Charge verification follows Title 24 guidelines and manufactures procedures. This is to ensure the system is delivering the capacity and operating temperatures needed to provide ideal comfort settings all Summer long.
Homes are getting tighter and tighter these days. Builders used to say that a home should breathe. Building scientists conclude that when we tighten a building envelope, make up fresh air needs to be introduced. A leaky home loses efficiency through leaky windows, doors and ductwork.
Adequate exhaust systems for bathrooms and kitchens are essential. But, there are other ways to bring fresh air into the house without giving up energy efficiency.
Blower Door Testing
A Blower Door is used to test the tightness of a structures envelope. It’s also helpful in identifying where these leaks are coming from. Imagine a 30 MPH wind blowing out of a light switch. That’s what a Blower Door can help us find. This test also shows how much duct leakage is to the outside of the conditioned space.
Utility Savings Assessment
Assessing your utility bills is a big step to identifying wasteful appliances and realizing energy savings. This is critical step to justify upgrades or not.
Our technicians will inspect the type and levels of insulation in your home. There is a huge benefit to adding insulation in the attic space. First, you may be able to down-size an air conditioning and heating system. Ultimately You keep more of the heated or cooled air in your home longer. Remember, when your HVAC equipment is turned off, it is 100% efficient.
