Water Heater Service in San Gabriel Valley, CA

Is your water heater acting up? Call Cypress Air at 626-963-9810 to service or replace your water heater in San Gabriel Valley and nearby service areas.

Hot water isn’t a luxury—it’s a daily necessity. Whether you’re taking a shower, doing laundry, or washing dishes, your water heater works hard to keep your household running. When it fails, everything grinds to a halt. That’s where we come in.

Don’t put up with lukewarm water or odd noises from your water heater any longer. We’re here to resolve any issue, offering everything from speedy repairs to brand-new installations to ensure your hot water is always reliable.

Your water heater works hard every day. Over time, minerals build up, parts wear down, and small issues can turn into costly repairs. That’s why routine maintenance is important.

With regular service, you can:

  • Extend the life of your water heater
  • Improve energy efficiency
  • Reduce the risk of leaks
  • Catch problems early
  • Lower your monthly utility bills

Whether you have a traditional tank or a tankless system, our trained technicians know how to keep it running at its best.

While tankless technology gains popularity, the traditional tank-style water heater remains the workhorse for countless homes in Southern California, reliably providing hot water for everyday needs.

At Cypress Air, our technicians possess extensive experience with all major brands and models of traditional water heaters, ensuring they operate safely and efficiently for years to come.

Our specialized services for traditional tank water heaters include:

  • Routine Tank Flushing – We thoroughly flush your tank to remove sediment buildup, improving efficiency and extending its lifespan.
  • Anode Rod Inspection – We check and replace the anode rod as needed to prevent internal tank corrosion and protect your investment.
  • Pressure Relief Valve Testing – This crucial safety device is tested to ensure it’s working correctly and preventing dangerous pressure buildup.
  • Thermostat & Element Diagnostics – We accurately diagnose and repair issues with your thermostat or heating elements to restore proper hot water.
  • Leak Detection & Repair – We swiftly identify and fix any leaks to prevent water damage and ensure your tank’s integrity.

Embracing the future of home comfort, tankless water heaters are rapidly gaining popularity in San Gabriel Valley and surrounding areas for their remarkable efficiency and ability to provide a continuous supply of hot water on demand.

Unlike traditional tanks, these compact units heat water instantly as it flows through, eliminating standby energy loss and ensuring you never run out of hot water.

Regardless of its age, or brand name, our specialized services for tankless water heaters include:

  • Annual Descaling & Flushing – We perform critical descaling to remove mineral buildup inside the heat exchanger, a common issue that can reduce efficiency and flow.
  • Combustion & Venting System Checks – We inspect the combustion system and venting to ensure safe and efficient operation, preventing harmful exhaust issues.
  • Inlet Water Filter Cleaning/Replacement – We clean or replace the vital inlet water filter, protecting the unit’s internal components from sediment and debris.
  • Gas Pressure & Flow Rate Calibration – We fine-tune gas pressure and water flow rates to optimize heating efficiency.
  • Error Code Diagnostics & Sensor Testing – We quickly interpret error codes and test crucial sensors to pinpoint specific repair issues.

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.

    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.

    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.
