Coming home to find your air conditioner blowing warm air can be more than just uncomfortable—it can be downright distressing. While this common air conditioning problem can stem from various issues, understanding the causes can help you determine whether it’s a simple fix or time to call in the professionals.
It’s helpful to understand how your air conditioning system works before going over the problems. Your AC unit operates on a relatively simple principle: it uses refrigerant to absorb heat from inside your home and release it outside. The process begins when liquid refrigerant passes through indoor evaporator coils, absorbing heat from your home’s air and transforming into a cold gas. A fan then blows across these refrigerant-cooled coils, pushing cold air through your ductwork. The gaseous refrigerant carries the absorbed heat to your outdoor unit, where it releases the heat and returns to liquid form, continuing the cycle.
Refrigerant Issues: A Common Culprit
One of the most frequent causes of poor cooling performance is refrigerant-related problems. Your AC system relies on a specific amount of refrigerant to function properly. When refrigerant levels drop due to leaks, your system loses its ability to effectively cool your home. You might notice not only reduced cooling but also increased humidity levels inside your house, which make it feel even warmer than it actually is.
Refrigerant leaks require professional attention. They can be difficult to locate and repair, and only certified HVAC technicians can legally handle refrigerant. If you suspect a leak, it’s important to have it looked at quickly, as running your system with low refrigerant can cause additional damage to other components.
The Critical Role of Air Filters
What many homeowners don’t realize is that something as simple as a dirty air filter can cause their AC to stop cooling effectively. Your air filter works continuously throughout the year as it traps everything from dust and pollen to pet hair and lint. When these filters become clogged, they restrict airflow to your system, which can cause several problems such as:
Reduced cooling efficiency
Increased energy consumption
Potential system shutdowns
Accelerated wear on AC components
Possible damage to evaporator coils
The good news is that filter maintenance is something most homeowners can handle themselves. For optimal performance, change your filters every three months, or more frequently if you have pets or live in a particularly dusty area.
Evaporator and Condenser Coil Problems
Even with regular filter changes, your system’s coils can develop issues over time. The evaporator coil, located inside your home, is particularly susceptible to mold and mildew growth due to constant moisture exposure. When coils become dirty or damaged, they can’t efficiently transfer heat, which leads to poor cooling performance.
Frozen coils are another common issue, often resulting from low refrigerant levels or airflow problems. If you notice ice building up on your indoor unit, turn off your system immediately and contact a professional to prevent further damage.
Ventilation and Airflow Obstacles
Sometimes the problem isn’t with your AC unit itself but with the path the air takes through your home. Several ventilation issues can prevent proper cooling, including:
Blocked or closed supply vents
Clogged return air registers
Damaged or leaking ductwork
Improperly sized ductwork
Pest damage to ventilation systems
Take a moment to inspect all visible vents in your home. Ensure they’re open and unobstructed by furniture, curtains, or other items. If you notice certain rooms aren’t cooling properly while others are fine, this could indicate a ductwork problem requiring professional inspection.
Thermostat Troubles
Before assuming your AC has a major problem, always check your thermostat first. Sometimes the solution is as simple as:
Verifying the system is set to “Cool” instead of “Heat”
Ensuring the temperature setting is correct
Checking/replacing thermostat batteries
Confirming the thermostat is properly calibrated
If your thermostat isn’t functioning correctly, your AC won’t know when to turn on or off. This will lead to comfort issues throughout your home.
The Value of Preventive Maintenance
Many AC problems can be prevented through regular maintenance. Scheduling professional tune-ups twice yearly—ideally in spring and fall—can help:
Identify potential problems before they become serious
Maintain optimal system efficiency
Extend your AC’s lifespan
Prevent unexpected breakdowns
Save money on energy bills
Ensure proper cooling when you need it most
During these maintenance visits, technicians can clean coils, check refrigerant levels, inspect electrical connections, and ensure all components are functioning properly.

What Affects the Cost of Air Conditioning Installation?
During the warmer months, many homeowners in Salem, Oregon, and surrounding areas consider installing or upgrading their air conditioning systems. While the comfort provided by a reliable air conditioning unit is undeniable, it’s important to understand the factors that influence the cost of installation. Our team at Melton’s Heating & Air Conditioning lists these factors below to help you make a decision that balances your comfort needs with your budget constraints.
The Impact of Unit Size and Capacity
One of the main factors affecting air conditioning installation costs is the size and capacity of the unit. In the HVAC industry, size refers to the cooling capacity rather than physical dimensions. Residential air conditioning units usually range from 1.5 to 5 tons.
However, bigger isn’t always better when it comes to air conditioning. The concept of “right-sizing” is important as an oversized unit can lead to frequent system cycling, increased humidity levels, and uneven cooling with hot and cold spots. Proper sizing ensures optimal performance and energy efficiency which can help you save money in the long run.
Energy Efficiency Ratings: Understanding SEER
The Seasonal Energy Efficiency Ratio (SEER) is a critical factor in determining both the initial cost and long-term savings of your AC unit. SEER measures the total heat removed from a space during a typical cooling season divided by the total energy consumed.
While units with higher SEER ratings are more expensive up front, they offer greater energy efficiency, translating to lower utility bills over time. When considering AC installation costs, it’s important to factor in these long-term savings.
Installation Complexity
The complexity of the installation process can impact the total cost. Several factors can increase installation complexity, including:
Removing an older unit before installing the new one.
Difficult-to-access areas like cramped basements or attics.
The need for new ductwork or electrical rewiring.
The Importance of Choosing the Right Contractor
While it might be tempting to choose the lowest price, the HVAC contractor you choose can greatly affect both the initial cost and long-term performance of your AC system. Here’s why investing in an experienced, reputable contractor is crucial:
Proper installation ensures optimal efficiency and performance.
Experienced technicians can navigate complex installations more effectively.
Reputable contractors often offer warranties and guarantees on their work.
Long-Term Value vs. Initial Cost
When considering air conditioner installation, a high-quality and energy-efficient system installed by experienced professionals may cost more upfront but can offer major benefits, such as lower monthly energy bills, improved home comfort, and a longer system lifespan with fewer repairs.
Financing Options
If the upfront cost of AC installation is a concern, many reputable HVAC companies offer financing options. These can help you invest in a high-quality system without straining your immediate budget.

Save on Air Conditioning Costs This Summer with These Tips
Managing your home’s air conditioning becomes crucial as the summer temperatures increase. There’s a common belief that leaving the air conditioner on all day might be cheaper, even when you’re not home. While somewhat true, it’s essential to manage it wisely to avoid excessive energy use and increase your system’s lifespan.
The key to effective air conditioning is maintaining a consistent and moderate setting rather than drastically changing the temperature. Instead of turning off your AC when you leave and overloading it upon return, you should use it gradually; if you prefer a cooler temperature of 72 degrees Fahrenheit while at home, adjust the thermostat to about 79 degrees when you’re away. This keeps it from turning on and off excessively, which can use more energy and lead to quicker wear.
Cost-Saving Tips
Studies suggest significant annual savings on cooling by setting your thermostat 7 to 10 degrees higher for 8 hours each day. Use this strategy during the workday or at night to maximize efficiency. Additionally, take advantage of cooler evenings by opening windows to reduce air conditioner use and enjoy natural ventilation. Using a programmable thermostat can increase savings by ensuring that your air conditioner only runs when necessary.
Why Consistent Air Conditioner Operation is Preferable
Turning your air conditioner off might seem like a good way to save energy, but it can backfire. When your house warms up during the day, reintroducing cool air requires more energy as your system works harder to combat heat buildup and humidity. Keeping your air conditioner running at a moderated higher temperature when you’re away can prevent these extreme fluctuations.
When Temperature Control is Critical
While keeping your AC on throughout the day is cheaper, it’s only cost-effective if managed correctly. It’s recommended to maintain a higher indoor temperature that is close to outdoor conditions but still comfortable. Avoid drastically low settings like 60 or 65 degrees, as trying to maintain such a low temperature against high outdoor heat will overwork your AC and inflate your energy bills.
