California Winter Heating Tips

You can avoid overspending on your winter energy usage by making an effort to improve your system’s efficiency. While these aren’t difficult steps to take, it’s easy to forget them while you’re winterizing the rest of your home. Use this checklist to keep the most important California winter heating tips close at hand.


Get a Professional Inspection and Tune-Up

Expert HVAC maintenance is essential for effective heating that won’t waste energy through the coldest days of winter. A tune-up addresses the wear and tear of the previous year’s use. The unit will perform more efficiently, and it will heat your home thoroughly. An annual tune-up will go a long way toward eliminating cold spots and ineffective heating in your home.


Check the Air Filter Regularly

Air filter changes rank high on lists of California winter heating tips. That’s because running a heat pump or furnace with a dirty filter will impede airflow. The system will have to work harder to meet your heating requirements, and this will lead to rising energy costs.


Additionally, a dirty filter forces the system to recirculate contaminants through your living spaces. This adversely affects your indoor air quality. Change your filter every 30 days for the best results.


Start the Season With Thermostat Maintenance

This is a good time of the year to install fresh batteries in your thermostat. You can test the unit by setting it to heat and adjusting the temperature higher. If the system doesn't start a heating cycle, your HVAC technician might need to calibrate the unit.


If you have an older model, consider upgrading to a smart thermostat. A mobile app will give you tighter control over your indoor climate and energy usage.


Decide Whether It’s Time for Duct Cleaning

If it has been three years since your most recent duct cleaning, it’s time to have a professional service your ducts. They will remove physical debris and unseen contaminants to ensure you’ll have cleaner indoor air throughout the winter. Additionally, you can use a damp cloth to wipe dust and cobwebs off the vents and registers.
