Why Your AC Is Struggling to Keep Up With the Heat

When the heat of summer is beating down on your house, you’ll want to know you can depend on your central AC to keep everything cool indoors. But you might discover this summer that your air conditioner isn’t keeping up with the heat the way it should: cold is coming from the vents, but the indoors feels hotter and stuffier, or there are hot spots around the house.

What’s happening? There are several major possibilities, which we’re going to discuss below. You can call us for any air conditioning repair in Junction City, OR you may need to get your cooling system back to peak condition.

Dirty Air Filters

A common reason an air conditioner may be underperforming is a dirty air filter. Air filters trap dust, dirt, and other airborne particles, preventing them from entering your AC system. Over time, these filters can become clogged, restricting airflow and reducing the system’s efficiency. A dirty filter makes your AC work harder, which can lead to overheating and eventual breakdowns. Thankfully, the fix is simple: put in a clean filter! (And keep up with regular changes.)

Refrigerant Leaks

Refrigerant is essential for your AC to cool the air. If there’s a leak in the refrigerant line, your AC won’t be able to cool your home effectively. Low refrigerant levels can cause the evaporator coil to freeze, leading to further inefficiencies and potential damage to the system. You must have HVAC pros handle leak repairs.

Blocked Condenser Unit

The condenser unit, usually located outside, is vital for expelling the heat absorbed from your home. If the condenser unit is blocked by debris such as leaves, dirt, or grass clippings, it can’t release heat effectively, causing your AC to struggle.

Improperly Sized AC Unit

An AC unit that’s too small for your home will struggle to cool the space, especially during extreme heat. On the other hand, an oversized unit will cycle on and off too frequently, not staying on long enough to cool the house. Our technicians can find out if your AC is the wrong size. If it is, the only option is to have it replaced.

Lack of Maintenance

Regular maintenance is key to keeping your AC running smoothly. Without it, minor issues can turn into major problems, reducing the efficiency and lifespan of your system. It’s not too late to have our team maintain your AC for the season.

Thermostat Issues

Sometimes, the problem isn’t with your AC unit but with your thermostat. An incorrectly calibrated or malfunctioning thermostat can cause your AC to run inefficiently or not at all.

Aging System

If your AC is more than 10–15 years old, it might be nearing the end of its useful life. Older systems are less efficient and more prone to breakdowns, especially during peak usage periods. We can consult with you about your AC’s future and if it’s more cost-effective to replace the unit or continue with repairs.
