How to Prep Your HVAC System for a Southern California Heatwave

California heatwaves can take a heavy toll on your home’s HVAC system, especially if you (and it) aren’t prepared. Your system will have to run harder to keep up, and that could mean increased wear and tear. Thankfully, you can take the following steps to HVAC heatwave prep in Whittier, CA, and keep your home comfortable no matter how hot it gets:


Replace Your Air Filter

One simple step you can take in response to an upcoming heatwave is to replace your HVAC system’s air filter. It is recommended to do so every three months in general, but either way, doing so will keep dust out of your home and protect your unit. If your air filter is clogged, it will put more strain on your system and can lead to a breakdown when temperatures rise.


Schedule an AC Tune-Up

You should schedule an AC tune-up every year to ensure efficient and reliable performance. An HVAC technician will carefully clean your system and fine-tune it for maximum cooling. They’ll also be able to spot and repair any potential issues that could lead to damage and reduce performance when you need your AC most.


Clean Your Air Ducts

Your air ducts play a key role in distributing cooled air throughout your home. But when dust and other debris build up, it can impede air flow and make cooling more difficult. Professional cleaning makes quick work of that dirt, letting your system work more efficiently while also improving your home’s indoor air quality.


Check Your Thermostat Settings

Ensure that your thermostat is accurately calibrated so you know that your system isn’t overworking itself to reach its set temperature. A smart thermostat is a great investment if you do not yet have one, as it will minimize your energy use while you’re away or as you sleep, all without compromising comfort.
