Furnace Services in San Gabriel Valley, CA

Don’t let the cold take over—your furnace keeps your home warm and comfortable. Call Cypress Heating at 626-963-9810 for appointments in San Gabriel Valley and nearby service areas.

Central heating is a system that warms your entire home by distributing heated air through ducts and vents. It uses a central furnace to generate heat, keeping your indoor space cozy and comfortable during cold weather.

These systems are more efficient than space heaters because they maintain even temperatures throughout the home. They also support better air quality by filtering out dust, allergens, and other pollutants.

The last thing you want on a freezing morning is for your furnace to stop working. If your heat goes out and you need fast, reliable repair service, Cypress Heating is here to help.

Furnaces are complex, and one issue can affect the whole system. Our trained technicians quickly find the problem and fix it fast—so your home stays warm and safe.

Here are common warning signs your furnace may need professional repair:

  • The furnace won’t turn on
  • The pilot light is out
  • Loud or strange noises during startup or operation
  • The main burner won’t light or stay lit
  • The blower won’t turn on after the burners are lit
  • The blower runs constantly without shutting off

If you notice any of these issues, don’t wait—call Cypress for expert heating repair.

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.

  • 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.
