3 Easy Fixes for Your AC this Summer

Is your air conditioner blowing warm air or making strange noises? Don’t sweat it! Before you call a professional HVAC technician, there are a few simple fixes you can try at home to get your AC back on track. At Probus, we’re here to help you stay cool and comfortable. In this post, we’ll share three easy DIY fixes for common AC problems. If these don’t solve the issue, our expert team is just a call away for fast, reliable service!

1. Check and Replace Your Air Filter

The Problem: A clogged air filter is one of the most common reasons your AC isn’t cooling properly. When the filter is dirty, it restricts airflow, making your system work harder and less efficiently.

The Fix:

• Locate the filter: Find your air filter, typically located in the return air duct or near the air handler.

• Inspect it: Hold the filter up to a light—if you can’t see through it, it’s time to replace it.

• Replace it: Swap out the old filter for a new one. Filters are affordable and available at hardware stores.

  
  

  Pro Tip: Replace your filter every 1–3 months, especially during Greensboro's hot summer months, to keep your AC running smoothly and save on energy bills.

Why It Works: A clean filter improves airflow, boosts efficiency, and can resolve issues like weak cooling or frequent cycling.

2. Clear the Condenser Unit

The Problem: Your outdoor AC condenser unit can get blocked by debris like leaves, grass, or dirt, especially after Greensboro’s windy storms. This reduces the unit’s ability to release heat, causing your AC to struggle.

The Fix:

• Turn off the power: For safety, switch off the AC unit at the breaker or disconnect switch.

• Clear debris: Remove leaves, twigs, and dirt from around the condenser (usually outside your home). Use a garden hose to gently rinse off dust, but avoid high-pressure settings.

• Check for obstructions: Ensure there’s at least 2 feet of clear space around the unit for proper airflow. Trim back any overgrown plants or bushes.

  
  

  Pro Tip: Schedule a professional cleaning with Probus: Heating & Cooling for a thorough condenser check, especially before Greensboro’s peak summer heat.

Why It Works: A clean condenser allows your AC to expel heat efficiently, improving cooling performance and preventing system strain.

3. Reset Your Thermostat

The Problem: Sometimes, your AC isn’t the issue—your thermostat might be! A misconfigured or malfunctioning thermostat can prevent your AC from turning on or cooling properly.

The Fix:

• Check the settings: Ensure your thermostat is set to “Cool” and the temperature is lower than the current room temperature.

• Replace batteries: If your thermostat uses batteries, swap them out for fresh ones (available at any Greensboro hardware store).

• Reset it: Turn off the thermostat, wait 5 minutes, and turn it back on. For smart thermostats, check the app for error messages or connectivity issues.

  
  

  Pro Tip: Upgrading to a smart thermostat can save energy and make your home more comfortable. Ask Probus about our thermostat installation services!

Why It Works: A properly functioning thermostat ensures your AC receives the right signals to cool your home effectively.
