How often should I replace my AC air filter in Salem?

You should check and replace your AC air filter every month during high-use seasons like summer, especially if you have pets or allergies.

Why is it important to clear debris around my outdoor AC unit?

Clearing a two-foot radius around your condenser helps prevent overheating, improves airflow, and allows your AC system to release heat efficiently.

What’s the ideal thermostat setting for summer comfort?

Setting your thermostat between 75-78°F is ideal for balancing comfort and energy efficiency during Salem's summer heat.

Salem's summers are getting hotter yearly, with average highs climbing into the mid-80s and heat waves pushing temperatures closer to 100 degrees. As the heat intensifies, your air conditioning system becomes more than a luxury; it’s necessary.

Neglected systems are more likely to break down, run inefficiently, and drive up your energy bills right when you need them most. Fortunately, proactive care can go a long way in keeping your home comfortable and your system running smoothly.

Below, we outline five steps you can take to keep your home cool and avoid expensive repairs, including:

Inspect and Replace Air Filters

Regularly replacing your air filter is one of the simplest yet most effective ways to improve your AC system's function. A clogged air filter restricts airflow, forcing your system to work harder and use more energy. This can cause unnecessary wear on the system, drive up utility bills, and reduce your home’s comfort.

To enjoy the best performance from your AC system, check and replace your air filter every month, especially if you have pets or seasonal allergies. Simply locate the return vent on your furnace, remove the old filter, and insert a new one.

A clogged air filter restricts airflow, forcing your AC to work harder and use more energy. A clean filter keeps your system running efficiently and ensures fresher indoor air quality.

Clear Debris Around the Outdoor Unit

Your condenser, or the part of your AC system that sits outside, needs space to release heat effectively. When surrounded by tall grass, weeds, or debris, the coils can quickly overheat, reducing their efficiency and increasing the risk of your system breaking down.

For optimal performance, maintain a clear two-foot radius around the condenser. Trim nearby plants, remove built-up debris, and gently rinse the exterior with a garden hose. This regular upkeep helps your system ventilate properly and cool more effectively, especially during Salem’s hottest summer days.

Check Thermostat Settings

Your thermostat plays a big role in your home’s energy use. If set incorrectly, your AC system could run longer than necessary or struggle to maintain the right temperature. Start by ensuring it’s set to “cool” mode and the target temperature is reasonable. Setting the thermostat between 75-78 degrees for most homes is ideal for balancing comfort with energy efficiency.

Your thermostat may need calibration or replacement if it isn’t responsive or accurate. Consider upgrading to a programmable or smart thermostat for better control, scheduling, and energy savings. This can help you manage your energy usage during peak summer months.

Examine Ductwork & Vents

Even a high-efficiency AC system can’t perform well if your ductwork is leaking or blocked. Cracks, gaps, or poorly sealed joints allow cool air to escape before it reaches your rooms, forcing your system to work overtime.

Make sure all vents are open and unobstructed by furniture, curtains, or clutter. A professional duct inspection can identify hidden leaks or insulation issues for a more thorough check. Keeping your ductwork in good shape ensures your cooled air gets where it’s needed without wasting energy.

Schedule a Professional Tune-Up

While basic upkeep helps, a full AC tune-up requires professional tools and expertise. Only trained technicians can safely check refrigerant levels, inspect electrical components, and deep-clean the evaporator and condenser coils. These tasks are essential to keep your system running safely and efficiently through the summer. A seasonal tune-up also helps catch minor issues before they become expensive repairs or mid-heatwave breakdowns.
