What You Need to Winterize Your San Jose Home's HVAC System


Even here in sunny San Jose, we sometimes get chilly weather and frosts. And, hey, it's even been known (very rarely, admittedly) to snow. So when the temperatures plunge, it's good to know you've got a reliable furnace, heat pump or other type of heating system to keep you warm.

Of course, as your HVAC ages, wear and tear on parts may cause the occasional breakdown, but the best way to ensure that doesn't happen when you need it most is to practice good maintenance habits -- among them, winterizing your HVAC.

Here are some tips on what to do before the season changes and you're having to turn up the heat:


We're not going to say it might not be warm enough to turn the air conditioner back on during the winter, but if you're fairly certain you won't be using it, take a few steps to "put it to bed." Clean up around the outdoor condenser unit, trimming grass and weeds, raking up leaves and clearing debris. Also trim limbs and branches that might damage the unit if they were to break in a storm.

If you're concerned about debris or dirt blowing into the unit, wrap it with a vinyl cover, but make sure it's not airtight. Be aware that rodents and vermin may be attracted to covered HVAC units as winter nesting places.


A clean filter is your best bet for ensuring your heating system runs efficiently throughout the winter, and that chances of breaking down are minimized. So keep the filter changed according to the manufacturer's instructions.


Call your HVAC technician to check out your heating system before fall arrives. You'll want him to look at the controls, thermostat, electric connections, condensate drain and blower, and to measure motor voltage and current. Gas lines, burners and heat exchanger should also be inspected.
