Whole-House Dehumidifier Service in San Gabriel Valley, CA

Feel the difference a drier, fresher home can make. Call Cypress Air at 626-963-9810 for whole-house dehumidifier sales and service in San Gabriel Valley and nearby service areas.

A whole-house dehumidifier quietly pulls excess moisture from the air in every room, helping your home stay cool, clean, and comfortable. Say goodbye to musty smells, sticky rooms, and mold worries—especially during our humid spring and summer seasons in the San Gabriel Valley.

Breathe easier and enjoy a healthier, more balanced home environment with the power of whole-home moisture control!

Built-in dehumidifier systems are designed to work seamlessly with your home’s HVAC system, pulling excess moisture from the air as it circulates through your ductwork. This keeps humidity levels in check throughout your home, helping to create a cooler, drier, and more comfortable living space—especially during warm, humid months.

We install and service two types of whole-house dehumidifiers. Each type has a unique way of removing moisture from the air, but they all work toward the same goal: protecting your home from high humidity and improving indoor air quality.

  • Refrigerant-Based Dehumidifiers – Similar to how an air conditioner works, these systems use coils to cool and condense moisture from the air, which is then drained away. They’re effective and energy-efficient for whole-home use.
  • Ventilating Dehumidifiers – These units bring in fresh outdoor air, filter it, and remove excess moisture before sending it through your home. They’re great for improving both humidity control and air freshness.

Managing indoor humidity isn’t just about comfort—it helps reduce mold growth, musty odors, and allergens, while also protecting furniture, flooring, and your HVAC system itself.

As a trusted Lennox Premier dealer, Cypress Air specializes in the installation and service of Lennox whole-house dehumidifiers—and we also work with other top brands like Carrier and AprilAire to bring you the best in indoor moisture control.

Our experienced technicians ensure your dehumidifier works seamlessly with your existing HVAC system for balanced humidity and cleaner, drier air throughout your home. Whether you’re dealing with muggy summers or hidden moisture issues, we’ll help you choose the right dehumidification system for your space. Here’s what we offer:

  • Trusted Brands – We install and maintain whole-house dehumidifiers from proven manufacturers known for performance and durability.
  • Expert Recommendations – Our team will help you select the right system based on your home’s size, layout, and existing moisture challenges.
  • Tailored Solutions – We assess your indoor humidity levels and customize a system that promotes comfort, protects against mold, and improves air quality.
  • Professional Installation & Support – From initial setup to fine-tuning system performance, we ensure your dehumidifier is installed right and ready to go.
  • Ongoing Maintenance – Regular service keeps your system running efficiently, extending its life and ensuring it continues to keep humidity in check year-round.

Your comfort is our priority. If something doesn’t feel right after we’ve installed your whole-house dehumidifier, contact us—we’ll make it right. Our service manager will follow up promptly to ensure you’re satisfied with the results.

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.
