Winter may be mild in San Diego, but heating costs can still sneak up on homeowners, especially if your home is wasting energy without you realizing it. The good news? Many of the most common efficiency problems are simple to fix, and your HVAC system can play a big role in lowering bills and keeping your home comfortable.
1. Air Leaks Around Doors and Windows
Even small gaps let warm air escape and cold air creep in, forcing your heater to work harder.
Quick fix: Add weatherstripping or caulking to seal leaks. This small upgrade can make a big difference.
2. Old or Dirty Air Filters
A clogged filter restricts airflow and decreases efficiency, often causing higher energy bills and reduced heating performance.
Fix: Check and replace your filter every 1–3 months during the winter.
3. Thermostat Settings That Work Against You
Many homeowners accidentally waste energy by keeping the thermostat too high or frequently adjusting it.
Better option: A programmable or smart thermostat does the work for you, optimizing comfort and energy use, even when guests come and go during the holidays.
4. Poor Insulation
Older homes often have insulation that’s thin, aging, or missing entirely in key areas like attics or crawl spaces.
Why it matters: Without insulation, heat escapes quickly, and your HVAC system runs longer to keep up.
5. Skipping Seasonal Maintenance
Even a well-installed system becomes less efficient over time if it’s not cleaned and tuned regularly.
A professional tune-up can:
- Improve airflow
- Maximize heating efficiency
- Catch small issues before they turn into expensive repairs
Small Fixes That Add Up
When your home is sealed, insulated, and maintained properly, your HVAC system doesn’t have to work overtime, resulting in lower bills, better comfort, and a longer equipment lifespan. If you want to make sure your system is running at peak performance this winter, scheduling a seasonal checkup is a great place to start.
