HVAC FAQs for Ontario, CA Homeowners
How often should I schedule HVAC maintenance?
We recommend having your system serviced twice a year, once in the spring for cooling and once in the fall for heating. Regular maintenance improves performance and helps prevent costly breakdowns.
What’s the average lifespan of an HVAC system in Ontario, CA?
Most systems last 12–15 years, but proper maintenance can extend their life. If your unit is more than a decade old and experiencing frequent issues, replacement might be the most cost-effective option.
What size HVAC system does my Ontario, CA home need?
The right HVAC system size isn’t one-size-fits-all. It depends on key factors like the size of your home, how well it’s insulated, how many windows it has, and the weather patterns in Ontario, CA. With scorching summers and cooler winter months, choosing an appropriately sized unit is essential to avoid energy waste and uneven temperatures. At Year Round Heating & Air, we conduct a detailed load assessment to ensure your new system is perfectly matched to your home’s specific needs.
Do I need to replace my thermostat when I upgrade my HVAC system?
Not always, but in many cases, a new thermostat can improve efficiency and give you more control over your indoor environment. Smart thermostats are especially helpful for optimizing comfort and reducing energy use.
What are signs my HVAC system needs repair?
Strange noises, uneven temperatures, poor airflow, frequent cycling, and rising utility bills are all signs that your HVAC system is in need of professional attention.
