Check for a Dirty Air Filter

Common AC Problems Caused by a Dirty Filter

A dirty or clogged air filter is one of the leading causes of many air conditioning issues. If the filter is full of dirt and dust, your system might experience the following problems:

• Low airflow from the vents
• Ice forming on the refrigerant lines
• A frozen evaporator coil
• Water leakage from the air conditioner
• Hot or cold spots and difficulty maintaining set temperatures
• Higher energy bills than usual
• Equipment malfunction or failure

What to do: Take a look at your air filter. If it appears dirty or clogged, replace it with a new one. A dirty filter acts like a barrier, restricting the airflow into your system and causing your AC to struggle. This lack of airflow can trigger several issues and might eventually lead to a complete system breakdown.

How Often Should You Replace Your Air Filter?

The frequency of replacing your air filter depends on various factors like the type of filter, your home’s environment, and your HVAC usage. In general, it’s recommended to replace standard filters every one to three months. Homes with pets, smokers, or family members with allergies may require more frequent changes.

There are several types of air filters to consider, including HEPA filters, which capture small particles like dust and allergens, pleated filters for longer life and better filtration, and fiberglass filters, which are budget-friendly but less effective for fine particles. Washable filters can be cleaned and reused but need regular maintenance.

Consistently changing your air filter not only improves the air quality in your home, reducing the risk of respiratory issues, but also helps your central AC system run efficiently, extending its lifespan. Regular filter replacement is a small but significant step in maintaining a healthy and comfortable living environment.

Check Your Thermostat Settings

Common AC Problems Caused by Incorrect Thermostat Settings

Something as simple as an incorrect thermostat setting can also cause a lot of confusion. Here are some issues you might encounter if the thermostat isn’t set properly:

• Warm air blowing from the vents
• The air conditioner won’t turn on

What to do: Head over to your thermostat and double-check that it’s set to “COOL” mode rather than “HEAT.” It’s easy to overlook, especially during seasonal transitions when temperatures fluctuate. Many service calls have been made only to find that the thermostat wasn’t set correctly.

How to Choose the Right Thermostat for Your Home?

Selecting the right thermostat is key to optimizing your home’s comfort and energy efficiency. There are three main types to consider: manual, programmable, and smart thermostats. Manual thermostats are basic and reliable but require manual adjustments, making them less efficient. Programmable thermostats allow you to schedule temperature changes throughout the day, helping you save energy when you’re not home.

However, for the most control and convenience, smart thermostats are a top choice. These devices learn your preferences, allow remote access via smartphone apps, and integrate with home automation systems. When choosing a thermostat, consider factors like your HVAC system compatibility, the size of your home, and your budget. Upgrading to a smart thermostat can lead to significant energy savings and improved comfort, especially in hot climates like Las Vegas, where efficient cooling is essential.

Check Your Air Conditioner Circuit Breakers

Common Central AC Problems Caused by Tripped Breakers

When your AC won’t start, it might be due to a tripped circuit breaker. A tripped breaker interrupts the electrical flow, causing your AC system to lose power.

What to do: Go to the main electrical panel of your home and look for breakers that aren’t in the “ON” position. If the circuit breakers are labeled, find the one that controls the air conditioner. Flip any tripped breakers back to the “ON” position. If the breaker immediately trips again, avoid repeatedly resetting it, as this indicates a more significant electrical issue requiring a professional inspection from URBN Home Services.

What Are the Common Signs of Electrical Issues in an AC Unit?

Electrical issues in your air conditioning unit can lead to serious problems if not addressed promptly. Common warning signs include frequently tripped circuit breakers, which indicate that your central AC is drawing more power than the system can handle. Additionally, burning smells from the unit could point to overheating wires or a failing motor, while unusual buzzing or humming noises often signal electrical component failure.

The underlying causes can range from faulty or loose wiring, overloaded circuits, to aging or failing electrical components. While you may be able to reset a tripped breaker, persistent electrical issues require professional intervention. Attempting to repair wiring or electrical problems without proper training can be dangerous and lead to further damage. In these cases, contacting a licensed technician from URBN Home Services is the safest course of action to avoid potential safety hazards and ensure your AC operates smoothly.

Check Your Outdoor Unit

Common central AC Problems Caused by a Dirty Outdoor Unit

The outdoor unit, or condenser, is essential for releasing heat from your home. When dirt, leaves, or other debris accumulate on or around the unit, it can lead to problems such as:

• Higher energy bills
• Warm air blowing through the vents
• Poor cooling performance
• Frequent breakdowns or repairs

What to do: Step outside and examine the exterior of your outdoor AC unit. If you notice a buildup of dirt, gently rinse it off with a garden hose using a low-pressure setting. Keep an eye out for any foliage or fencing within two to three feet of the unit and clear away any obstructions to maintain proper airflow.

Why Regular Outdoor Unit Maintenance is Essential for Energy Efficiency

Maintaining your outdoor AC unit is crucial for optimizing energy efficiency and avoiding unexpected breakdowns. Over time, dirt, leaves, and other debris can accumulate on and around your outdoor condenser. This buildup restricts airflow and forces your system to work harder, leading to higher energy bills and increased wear and tear.

To keep your unit running efficiently, start by turning off the power. Use a garden hose with a gentle spray to carefully wash away dirt from the condenser coils—avoid using high pressure, as it can damage the fins. Additionally, keep at least 2-3 feet of clearance around the unit by trimming plants and removing obstacles.

Consider using gravel or mulch around the condenser base to prevent dirt accumulation. This simple, regular upkeep will help your central AC function effectively and reduce energy consumption, making it a valuable practice for homeowners in hot climates like Las Vegas.

Check All Air Vents

Common AC Problems Caused by Blocked Air Vents

Blocked or closed air vents disrupt airflow, creating various problems that impact your AC’s performance:

• The AC struggles to cool your home evenly
• Ice forms on refrigerant lines
• The evaporator coil freezes
• Water leaks from the air conditioner
• Compressor damage
• Blower motor issues
• Increased duct leakage, resulting in higher energy bills

What to do: Walk through each room in your home and make sure that all return and supply vents are open and unblocked. Even in rooms that are rarely used, keeping vents open is crucial for balanced airflow. Common culprits like rugs, curtains, or furniture can easily obstruct these vents, so inspect carefully.

Homeowners sometimes intentionally close vents in unused rooms, hoping to save on energy costs. However, this can actually increase your bills and put unnecessary stress on your air conditioning system.

How Can Closing Vents Affect Your HVAC System?

It’s a common misconception that closing vents in unused rooms saves energy and money. In reality, closing vents can create pressure imbalances in your HVAC system, leading to several issues. When vents are closed, air is forced to find alternate paths, causing increased pressure within your ductwork. This added pressure can lead to duct leaks, uneven temperature distribution, and additional strain on your system, which ultimately reduces energy efficiency.

Moreover, a strained HVAC system must work harder to maintain desired temperatures, leading to higher energy bills and potential damage to key components like the blower motor and compressor. Instead of closing vents, consider alternative solutions such as zone control HVAC systems. These systems allow you to regulate temperatures independently in different areas of your home without causing strain on the overall system. Balancing airflow is crucial for achieving energy efficiency and extending the lifespan of your HVAC system.
