When it comes to keeping your home comfortable year-round, few things matter more than your HVAC system. Yet many homeowners don’t realize just how much regular maintenance affects their system’s performance and their wallet.
At John Padilla Plumbing, Heating & Air, our San Diego-based team of HVAC professionals has spent decades helping homeowners stay cool in the summer, warm in the winter, and stress-free all year long. Whether you’re wondering how often HVAC should be serviced, or when is it time to replace your AC, we’re here to clear the air, literally.
What Is HVAC?
HVAC stands for Heating, Ventilation, and Air Conditioning. It’s the system responsible for circulating clean, comfortable air throughout your home. A properly maintained HVAC system doesn’t just keep you cozy; it improves indoor air quality, lowers energy bills, and extends equipment life.
For homes in San Diego’s warm climate, your AC works overtime. That’s why regular HVAC service isn’t just a good idea, it’s essential.
How Often Should HVAC Be Serviced?
- Air Conditioners: Service at least once every year before summer.
- Mini Split Heat Pumps: Service twice a year since they provide both heating and cooling.
- Full HVAC Systems: Inspect and maintain every 6 months to ensure efficiency and longevity.
Skipping service might save you a few bucks today but could cost you thousands of repairs or energy waste later.
Why Regular HVAC Maintenance Matters
Think of HVAC maintenance like changing your car’s oil. You wouldn’t drive for years without a tune-up, and the same logic applies to your home’s comfort system.
Routine service helps:
- Catch small problems early before they become major repairs.
- Improve efficiency and lower energy bills.
- Maintain your warranty (most manufacturers require regular service).
- Extend system lifespan; a well-maintained unit can last 15 years or more.
Our San Diego HVAC technicians at John Padilla Plumbing check refrigerant levels, clean coils, inspect ductwork, tighten electrical connections, and ensure everything runs safely and efficiently.
When to Replace Your HVAC System
Wondering how often should you get your AC replaced? On average, most air conditioners last 10–15 years, sometimes longer with consistent maintenance.
You might need to replace your system if:
- It’s 10+ years old and breaks down frequently.
- You’ve noticed rising energy bills despite routine tune-ups.
- Your home has uneven cooling or poor airflow.
- It still uses R-22 refrigerant, which has been phased out.
New high-efficiency systems, especially mini split heat pumps, can dramatically cut your utility costs and give you better control over comfort in every room.
