No Cool Air? Try These A/C Troubleshooting Tips

Here are five common reasons your air conditioning isn’t working.

air conditioning repair Caroline County, MD We’re approaching the time of the year when families in Central Delmarva need to run their central air conditioning virtually every day — and often all day. Having a cooling system that won’t deliver cold air on a sweltering afternoon can significantly harm your quality of life.

At Poore’s Propane and Oil, we have a skilled and experienced HVAC team that’s committed to being there for customers when they need an emergency air conditioning repair. But if you’re dealing with a central A/C issue at your home, you might be able to fix it yourself and avoid a service appointment. Here are five standard causes for a non-responsive A/C that you can troubleshoot on your own.

1. Your Thermostat Settings

The issue here could be as simple as a thermostat that isn’t set to “cool” or “air conditioning” mode. Ensure your settings are correct and also that your thermostat’s temperature is 5 degrees cooler than your current room temperature. If not, your A/C equipment is likely working fine, but it isn’t getting a signal to come on. Fix the settings, and you could be good to go.

Does your battery-powered thermostat have a totally blank screen? Try inserting a fresh set of batteries and see if this gets the A/C running again.

2. A Blocked Vent

Even if your central cooling system is circulating cold air, it can’t reach your living spaces if area rugs, houseplants, furniture or other obstructions block your vents. The same is true if your rooms’ vents are closed. Take a walk through your home and make sure that your vents are open and clear of obstructions.

3. An A/C Power Issue

Your cooling equipment may not be receiving the electrical power it needs. Check the following potential problems:

  1. Look at the power switches of your indoor and outdoor A/C equipment and confirm that they’re set to ON.
  2. Look at the breaker box in your home. Has the circuit breaker supplying power to your A/C tripped?
  3. If your home has a fuse box, ensure a fuse hasn’t blown, cutting off power to your cooling system.

4. A Dirty Air Filter

The air filter in your forced air HVAC system prevents airborne pollutants like dust, mold, pollen and other toxins from circulating into your home. This filter can become clogged with debris in a relatively short period. The result is blocked airflow. Luckily, addressing a dirty air filter is easy.

You can typically locate your filter in your furnace’s blower compartment or a return duct. If you have a dirty reusable filter, wash it off, let it dry and return it to its slot. Disposable filters must be replaced when they become dirty. Don’t worry, though; these air filters are available at most home stores and don’t cost much money.

We recommend you check your air filter at least once a month in the summer and winter.

5. A Clogged Outdoor A/C Unit

Airflow to your cooling system can also become obstructed if your outdoor A/C unit is clogged with vegetation or debris. Please take a look at this unit and clear away 18 to 30 inches of clear space around it. If there are grass clippings stuck to it, hose it off for a minute. Also, never stack anything on top of this piece of equipment.
