While San Diego is known for its mild, year-round climate, the winter months still bring cooler temperatures, especially in the evenings and at night. Properly preparing your heating, ventilation, and air conditioning (HVAC) system will help ensure comfort in your home and avoid unexpected breakdowns at the worst possible time.
In short, to prepare your HVAC system for the cold, you need to check the filters, ensure the thermostat is working correctly, and inspect the outdoor unit. If you want the system to operate efficiently and safely all winter, you’ll need professional maintenance. This will help avoid unexpected breakdowns, save you money on bills, and ensure there are no issues with leaks.
Now, let’s look at the details.
Start with the basics:
checks you can do yourself
The transition from cool to warm isn’t just about pressing a button. If you want your heating system to work without issues, you should perform a few simple checks.
- Replace the filter:
A filter clogged with dust and dirt is the main reason for a drop in efficiency. It obstructs airflow, forcing the system to work harder. Regular filter replacement is the simplest and most effective way to cut heating costs and extend the life of your equipment. - Check the thermostat:
Make sure your thermostat is switched to “Heat” mode and is working correctly. Try setting the temperature a few degrees above the current room temperature to ensure the system turns on. - Inspect the outdoor unit:
If you have a heat pump, make sure the outdoor unit is free of leaves, twigs, and other debris. Good air circulation is critically important for its efficient operation. - Listen to your system:
Pay attention to any unusual sounds when it turns on, whether it’s scraping, knocking, or humming. This could be an early sign of a furnace malfunction or a heat pump issue.

Energy saving in a mild climate
