Indoor Air Quality

Indoor Air Quality in Santa Clarita, CA

─ If you notice your family or pets are getting sick more often, or your house smells funny, these are indications you have compromised indoor air quality.

You’re not alone – the U.S. Environmental Protection Agency estimates some homes may have air more than five times more polluted than the air outside.


Don’t fret – the professionals at Rays Heating and Cooling can help with air purification and improved air quality. There are some easy upgrades that can help everyone in your home breathe easier. A Rays Heating and Cooling technician will review your needs and provide you with options on what can be done to improve your indoor air quality.

  • Whole House Fans

    Whole house fans are a great compliment to your A/C system. Whole house fans are ceiling/attic mounted fans that work to push hot air out of the house and attic while pulling in cool air from outside. This allows you to take full advantage of cooler outside temperatures and saving you from running the A/C. We’d love to help you determine if a whole house fan would be helpful for you—go ahead and give us a call, and we’d be happy to discuss!

  • Thermostat

  • Zoning

    The biggest complaint we get from customers is the temperature difference in their homes. Whether it is an upstairs, downstairs or bedroom vs living area problem. The way to fix these degree differentials is by zoning the heating and air conditioning system. You will have multiple thermostats and motorized dampers that will adjust the flow of air to different areas of the home, creating the ultimate in home comfort. We can provide a free estimate to add a zoning system, or schedule you for a service call to adjust your current set up. If you want to get into the nitty gritty of the air flow we can set up an air flow diagnostic where we will measure the output in each register and providing a recommendation on how to better move your air.

    The iWave is a new technology that purifies the air you breathe! It works by using ions to break down pathogens and pollutants into harmless compounds (like water vapor).

Dust, pet dander, and debris inside the home, and pollen and pollution from the outside all contribute to poor indoor air quality. Your home’s HVAC system circulates air inside your house and some outside air, cooling it and pumping it through your house. It is important to have better filtration and/or air purification set up inside your duct system to trap and prevent these contaminants from continuing to circulate throughout the home.


An air purification system works in two ways:


  • Removes solid debris like dust, pollen, and pet dander from the air, trapping it in a strong filter.
  • Purifies the air by sterilizing the air, killing airborne viruses and bacteria.



We use advanced technology to make your home’s air breathably pure. When your indoor air quality is better, your house is more comfortable.
