AJ Heating & Cooling - Hayward's Licensed HVAC Services

Our $65 service fee covers the initial diagnostic visit to your Hayward home. One of our NATE-certified technicians will come out, assess your HVAC issue—whether it's a furnace not heating, an AC not cooling, or a specific component like an air handler fan—and provide you with a clear, detailed estimate for the repair work. This upfront approach ensures you know exactly what's needed and what it will cost before any work begins.

Absolutely. Smart thermostat issues are a common frustration for Hayward homeowners, often stemming from wiring compatibility, Wi-Fi settings, or firmware glitches. During our service call, our technicians don't just replace thermostats; we troubleshoot the root cause. We'll ensure your new or existing smart thermostat is correctly installed and configured for your specific HVAC system, helping you regain reliable control over your home's temperature and efficiency.

For the Hayward climate, we often recommend heat pumps and ductless mini-split systems, which provide efficient both heating and cooling—a great fit for our milder winters and warm summers. As part of our service, we can perform a building energy audit to identify the best solution for your home's layout and insulation. We offer financing through GoGreen Financing to make these upgrades more manageable, helping you improve comfort while potentially lowering your energy bills.
