Air conditioning is essential for comfort in Van Nuys, especially during the peak summer months. While routine maintenance can keep your system running smoothly, homeowners sometimes make avoidable mistakes when attempting repairs or basic upkeep. These missteps can lead to reduced efficiency, costly breakdowns, or even voided warranties.
In this article, you’ll learn practical tips for AC repair—and just as importantly, what not to do if you want to keep your cooling system operating efficiently and safely.
1. Don’t Ignore Unusual Sounds or Smells
One of the biggest mistakes homeowners make is brushing off strange noises or odors coming from the AC unit. A buzzing sound might mean electrical issues, while rattling could point to loose parts. Musty smells might indicate mold in the ductwork or condensate lines.
Tip: Don’t assume the issue will go away on its own. Address these warning signs early to prevent further damage.
2. Don’t Block Air Vents
It may seem harmless to place furniture or curtains near vents, but blocked airflow forces the system to work harder, increasing wear and tear.
Tip: Keep all supply and return vents unobstructed to allow for even cooling and better system performance.
3. Don’t Skip Filter Changes
Neglecting to replace your air filter regularly is a common mistake that reduces airflow and causes the system to overheat or freeze. This small component has a big impact on system health.
Tip: Replace filters every 1 to 3 months, especially during periods of heavy use or if you have pets or allergies.
4. Don’t Attempt Complex Repairs Yourself
Trying to fix electrical components, refrigerant lines, or internal parts without proper training can be dangerous and cause permanent system damage. DIY repairs often void warranties and could lead to injury or costly replacement.
Tip: Always call a licensed technician for complex or technical issues. For fast and dependable service, reach out to an expert in AC repair in Van Nuys for a professional evaluation and repair.
5. Don’t Overwork Your System
Setting your thermostat extremely low to cool the house faster doesn’t work and strains the compressor. The system will cool at the same rate regardless of the set temperature.
Tip: Set your thermostat to a moderate temperature (around 76–78°F) for efficient cooling. Use ceiling fans to help circulate air more evenly.
6. Don’t Forget the Outdoor Unit
Homeowners often focus only on the indoor components, forgetting that the outdoor condenser needs care too. Leaves, dirt, and debris can clog coils and reduce heat release, leading to poor performance.
Tip: Keep a 2-foot clearance around the outdoor unit and clean it gently with a hose every few months (with the power off).
7. Don’t Delay Necessary Repairs
Small issues like inconsistent cooling or short cycling can quickly turn into larger problems if ignored. Waiting too long can lead to compressor failure or high repair costs.
Tip: Schedule repairs as soon as you notice performance changes. Preventative action saves money and ensures uninterrupted comfort.
Final Thoughts
Maintaining your AC system involves more than just knowing what to do—it also means avoiding the most common mistakes that lead to breakdowns and inefficiencies. From ignoring warning signs to attempting DIY fixes on complex components, these missteps can shorten your system’s lifespan and cost you more over time.
For homeowners in Van Nuys, staying cool and comfortable during the summer begins with smart decisions. Avoid these common repair pitfalls and rely on experienced professionals to keep your AC running at peak performance.
