Duct Cleaning, Testing, Repair and Replacement


Central air conditioning and heating are the top energy consumers in most California homes, so ensuring the efficiency of your entire HVAC system can yield big improvements in energy efficiency. When we think about saving energy, we usually focus on the furnace and air conditioner units, but a leaky duct system can reduce your climate control system’s efficiency 20% to 30%. These leaks can bring unwanted dust, unconditioned outdoor air and humidity into your living space – and take money straight out of your wallet.

Duct Testing

Ongaro & Sons recommends, if your home is over seven years old, have your ducts professionally tested by a certified Home Energy Rating System (HERS) technician via an energy audit. If it is determined you have leaky ducts we are happy to give you a quote to repair or replace. Duct testing is also advisable whenever heating and air conditioning units undergo a diagnostic tune-up. Duct testing is recommended for any building where a forced air heating or air conditioning system is used.

Duct Cleaning

According to the U.S. Department of Energy, 25 to 40 percent of the energy used for heating or cooling a home is wasted. Contaminants in the heating and cooling system cause it to work harder and shorten the life of your system. Although filters are used, the heating and cooling system still gets dirty through normal use.

When an HVAC system is clean, it doesn’t have to work as hard to maintain the temperature you desire. As a result, less energy is used, leading to improved cost-effectiveness.
Indoor air quality is one concern that homeowners have when they decide to investigate air duct cleaning. In a typical six-room home, up to 40 pounds of dust is created annually through everyday living. Your heating and cooling system is the lungs of your home. The system taken air in and breathes air out.

Through normal occupation in a home, we generate a great deal of contaminants and air pollutants, such as dander, dust, and chemicals. These contaminants are pulled into the HVAC system and re-circulated 5 to 7 times per day, on average. Over time, this re-circulation causes a build-up of contaminants in the duct work.

While dirty ducts don’t necessarily mean unhealthy air in your home, school or workplace, they may be contributing to larger health issues or harboring contaminants that could cause serious problems for people with respiratory health conditions, autoimmune disorders or some environmental allergies.

How to choose the right Air Filter for you

Clean air delivery rate measures the effectiveness of air cleaning appliances. The higher the clean air delivery rate, the more effective the unit is at cleaning the room or home of airborne particles and allergens. The clean air delivery rate is recognized by the Federal Trade Commission (FTC) and the Environmental Protection Agency (EPA) as a fair and objective measure of various air cleaner technologies.


Why is it important to choose the right Air Filter?

Air filters and air cleaners control the quality of the air in your home by removing particles and allergens. In combination with the right air handler (your furnace) and the right controls (your thermostat) you can manage the indoor air quality of your home. Air filters and air cleaners should be programmed to remove particles from your home year-round, not only when you’re heating or air conditioning system is running.


Heating and air conditioning controls mean so much more than just a thermostat. With today’s modern controls it’s easy to integrate indoor air quality, zoning, ventilation, as well as remote temperature sensing, and portable comfort control. You can even monitor and control your heating, and air Conditioning system while away from home, using your iPhone. Call today to find out more.
