Whole-House Air Purifier Service in San Gabriel Valley, CA

Make your home’s air cleaner, safer, and healthier—with a whole-house air purification system. Call Cypress Air at 626-963-9810 for appointments in San Gabriel Valley and nearby service areas.

A whole-house air purifier, integrated with your HVAC system, actively senses and cleans the air throughout your home using powerful filtration. This process not only removes dust and particles but also neutralizes household odors and harmful volatile organic compounds (VOCs) by utilizing activated carbon.

Transform the air in every room with a whole-house air purifier and breathe easier knowing cleaner, healthier air circulates throughout your entire home.

Whole-house air purification systems are designed to work alongside your home’s HVAC setup, filtering indoor air as it moves through your ductwork. These systems capture dust, allergens, and other airborne particles to help create a cleaner, healthier living environment all year round.

We install and service two main types of whole-house air purifiers, each offering a different method of cleaning the air—but both are focused on improving air quality and protecting your home from airborne pollutants.

  • Mechanical Filtration (Media Filters) – This is the most common type and uses physical barriers to trap particles. These filters are rated by their MERV (Minimum Efficiency Reporting Value), which indicates their ability to capture particles of different sizes. For example, Lennox offers a range of media air cleaners in their Healthy Climate® line that use MERV 16, 13, or 11 filters.
  • Electronic Air Cleaners – These systems use an electrical charge to attract and trap airborne particles, offering a high level of filtration without restricting airflow. Lennox’s PureAir® system is one example of an advanced electronic air cleaner that combines multiple technologies to filter indoor air and reduce odors, chemicals, and airborne particles

Air purification, whether through air purifiers or other cleaning methods, offers significant benefits beyond just reducing dust. These benefits include cutting down on allergens, improving HVAC efficiency, and helping protect both your home’s surfaces and your family’s health.

As a leading Lennox Premier dealer in Southern California, Cypress Air specializes in the installation and service of Lennox whole-home air filtration systems. We also work with other leading brands like Carrier and AprilAire to provide top-quality air cleaning solutions for your home.

Our skilled technicians make sure your air purifier integrates smoothly with your current HVAC setup, helping to reduce airborne particles and improve indoor air quality throughout your entire house. Whether you’re tackling seasonal allergies or looking to remove dust and pollutants, we’ll guide you in choosing the ideal purification system for your household’s air quality needs. Here’s how we can help:

  • Leading Brands – We install and service high-performance whole-home air filters from manufacturers known for long-lasting quality and efficiency.

Customer Reviews

Our Customers Love Our Service . . Here’s Why

  • The job was promptly done

    Cypress Heating & Air texted that the technician was on his way, including a photo of him. Joshua arrived on time and replaced the filter for the furnace; necessary after the big Eaton fire. He inspected the system and used the blue booties over his shoes.
    MG in Pasadena, CA

  • Professional and on time

    Just had service from Joshua for my annual maintenance. He was very professional and did an excellent job. Would highly recommend him and Cypress. I have been a customer for over three years.
    Deborah in Glendora, CA

  • The technicians are great

    We have used Cypress for a few years now. We had an issue with our A/C and Joshua did a thorough inspection, was able to troubleshoot the issue and our A/C was up and going in no time. Great experience and service!
    James in Los Angeles, CA

  • Fast and efficient

    I had called the company that originally installed my mini-split system and they told me that I would have to wait for a month for an appointment. I called Cypress heating and they were here in two days. They took care of my issue and now I’m a loyal maintenance member.
    Luz in Arcadia

  • Made everything easy

    Got my second service from Cypress so they could check my heater as the winter cold sets in. Joshua did an excellent job. Came right in the time window agreed upon, gave me some good practical information on my unit, replaced the filter, and was able to make sure the system was running correctly.
    Pat in Monrovia, CA

  • Reliable and long-lasting

    Cypress Heating & Air has grown since I first meet Bob in 1994 and I see their trucks and vans everywhere. I still receive the same great service and look forward to continuing using Cypress Heating & Air for years to come.
