In Van Nuys, where temperatures often climb well into the 90s, air conditioning is not just about comfort—it’s about necessity. A properly functioning AC system keeps indoor environments cool, reduces humidity, and protects both health and property during long summer months. But like any machine, air conditioners require care, attention, and the occasional repair.
In this article, you’ll learn essential facts about AC repair, including how systems work, what can go wrong, and when it’s time to call in a professional. Whether you’re a new homeowner or just looking to better understand your cooling system, these insights can help you make smarter, more cost-effective decisions.
Learn How Your AC System Works
Understanding how your air conditioner operates is the first step in recognizing problems and avoiding unnecessary repairs. A standard central AC system has several key parts:
- Evaporator coil (indoor): Absorbs heat from inside the home
- Compressor (outdoor): Pressurizes refrigerant to circulate it
- Condenser coil (outdoor): Releases heat outdoors
- Thermostat: Signals the system to turn on or off
- Blower and ducts: Distribute cooled air through your home
When these components work together smoothly, your home stays cool. However, even one malfunctioning part can throw off the entire system.
Learn the Most Common AC Problems
Over time, wear and tear can affect your air conditioner’s performance. Here are the most common issues homeowners in Van Nuys encounter:
- Low refrigerant: Causes the unit to blow warm air or run continuously
- Dirty filters: Reduce airflow, increase energy use, and lead to coil freezing
- Thermostat issues: Result in uneven temperatures or no cooling
- Electrical problems: Cause the system to short-cycle or not turn on
- Drainage blockages: Lead to water leaks and moisture damage
Addressing these problems early can help prevent larger, more expensive repairs.
Learn the Warning Signs of a Failing System
Your AC system often gives signs that something isn’t right. Ignoring them may lead to complete system failure.
Watch out for these red flags:
- Strange noises like buzzing, rattling, or grinding
- Warm air coming from the vents
- Poor airflow in certain rooms
- Rising utility bills with no increase in usage
- Water or condensation near the indoor unit
If you notice any of these issues, it’s best to schedule service before the problem escalates.
Learn Why Professional AC Repair Matters
