Air Filter Service in San Gabriel Valley, CA

For AC and furnace filter replacements or installations in San Gabriel Valley and nearby service areas, call Cypress Air at 626-963-9810.

Clean air filters are key for good air and efficient HVAC. While DIY is an option, using a professional service like Cypress Air for regular changes has advantages. Our technicians will get the right filter installed correctly and can identify other system or air quality problems you might miss.

Letting Cypress Air handle your air filters is a smart move for peace of mind and protecting your system. Consistent professional service from us means filters are changed properly based on your needs. This helps keep your air healthier, your energy bills lower, and your furnace/AC lasting longer by preventing issues from dirty filters.

Your air filters play a vital role in keeping your home’s air clean and your HVAC system running efficiently. Knowing when to change them can save you money and improve your indoor air quality. While the general recommendation is every 1-3 months for standard filters, your system might be telling you it’s time for a change sooner. Keep an eye out for these warning signs:

  • A noticeable decrease in air coming from your registers.
  • More frequent dusting needed or a rise in allergy symptoms.
  • An unexpected jump in costs or strange sounds like whistling or straining.
  • The filter is clearly coated in dust and debris.
  • Your home isn’t reaching or maintaining the set temperature.
  • You can’t recall the last you last change.

Regularly changing your air filters offers a multitude of advantages for your home, your health, and your HVAC system. Make this simple maintenance task a priority to enjoy these key benefits:

  • Improved Indoor Air Quality – Fresh filters trap dust, pollen, pet dander, and other airborne irritants, leading to cleaner and healthier air for you and your family.
  • Enhanced HVAC System Efficiency – Clean filters allow for optimal airflow, reducing strain on your furnace and air conditioner, which can lower your energy bills.
  • Extended HVAC System Lifespan – By preventing dust and debris buildup, clean filters help your system run more smoothly and can prolong its overall lifespan, saving you money on costly repairs or replacements.
  • Reduced Allergy and Asthma Symptoms – Removing airborne allergens can significantly alleviate symptoms for those with respiratory sensitivities.
  • Prevention of Costly Repairs – Restricted airflow from dirty filters can cause overheating, frozen coils, and other system malfunctions, leading to expensive repairs.

Your comfort is our priority. If something doesn’t feel right after we’ve replaced and installed new air filters, 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.
