Implementation Tactics: Common HVAC Issues in Van Nuys and How to Fix Them

1. Clogged or Dirty Air Filters

This is the most overlooked issue and also one of the easiest to fix. Dirty filters reduce airflow, force your system to work harder, and spike energy bills. In extreme cases, they can even cause your system to freeze up or overheat.

Solution: Replace your filters every 1–3 months, especially during peak usage. Zodiac offers routine maintenance plans that include filter checks and replacement, keeping your system breathing freely.

2. Refrigerant Leaks

When your AC isn’t cooling well—especially during those 100-degree Van Nuys days—a refrigerant leak could be the culprit. Low refrigerant levels mean your system can’t absorb heat effectively, leading to longer run times and higher bills.

Solution: Have a professional technician inspect and recharge your system. Leaks should be fixed immediately to avoid compressor damage, which is one of the most expensive HVAC repairs.

3. Thermostat Malfunctions

A thermostat that misreads temperatures or loses connectivity can leave your home too hot or too cold. Older models may also lack the precision of newer, programmable thermostats, resulting in inefficient heating and cooling.

Solution: Test your thermostat settings and consider upgrading to a smart model. Zodiac’s heating services and cooling solutions often include thermostat calibration and replacements.

4. Uneven Cooling or Heating

Are some rooms freezing while others feel like a sauna? Uneven temperatures often stem from ductwork issues, blocked vents, or improper system sizing—common in older Van Nuys homes with retrofitted systems.

Solution: A professional HVAC inspection can identify duct leaks, insulation gaps, or zoning issues. Balancing airflow and optimizing duct design can improve comfort across your home.

5. Strange Noises or Constant Cycling

Clanking, banging, or constant cycling is your HVAC’s way of asking for help. These noises could signal a loose part, dirty blower motor, or electrical issue—and ignoring them can lead to system failure.

Solution: Don’t wait. Call a licensed technician for diagnostics and repairs. The team at Zodiac Heating & Air Conditioning, Inc. specializes in identifying unusual noises and restoring quiet, efficient operation.

FAQs

How often should I service my HVAC system in Van Nuys?

Given the heavy year-round usage in Van Nuys, HVAC systems should be serviced at least once a year—twice is better if you use both heating and cooling. Regular service helps prevent wear and keeps your system efficient. A professional tune-up can spot issues before they lead to breakdowns.

Why is my AC running but not cooling my house?

If your system is running but your home stays warm, it could be due to low refrigerant, a dirty condenser coil, or thermostat miscalibration. These issues reduce the system’s ability to remove heat effectively. A quick inspection by a certified technician can pinpoint the problem.

Is it normal for different rooms to have different temperatures?

No, significant temperature differences between rooms usually mean there’s an airflow or ductwork problem. It could also be caused by poor system zoning or a clogged air filter. Balancing your HVAC system can restore even comfort.

What’s the average HVAC lifespan in Van Nuys?

Most HVAC systems last between 10–15 years with proper maintenance. However, Van Nuys’ climate can accelerate wear if systems aren’t serviced regularly. Investing in annual maintenance helps extend equipment life and efficiency.
