Do you find it difficult to remain comfortable during the hot summer months due to an air conditioning issue? Many people experience the same difficulty as you do. Luckily, we at ND Cooling perform a lot of work each year helping service many AC system cooling problems for numerous business and home owners. The first step towards getting comfortable again in your space is to know what causes issues with your cooling systems. Let’s look at some of the most common reasons why your air conditioning will not work properly, and how we at ND Cooling can assist in getting you back to enjoying a comfortable space indoors again.
1. Dirty Air Filters: The #1 Culprit
A clogged or dirty air filter is by far the most common reason AC systems do not cool properly. When dust, fur (from pets) and other debris build up in your filter, it restricts the airflow through your unit, causing it to use more energy, and less efficient cooling. Higher energy bills and reduced cooling performance are two outcomes of having a dirty or clogged filter. You should check your filter on a monthly basis, and replace it every 1 to 3 months depending on usage and household conditions. Regularly checking your filters can be responsible for resolving around 50% of the cooling complaints that we at ND Cooling receive. Keeping your filters in good shape is a good investment in the long-term operation of your system, and in your comfort around your home.
2. Low Refrigerant: A Silent System Killer
Refrigerant is the lifeblood of your cooling system. If your AC is leaking refrigerant, it cannot absorb heat from your indoor air, resulting in warm airflow or complete system failure. Signs include hissing sounds, ice buildup on coils, or the unit cycling on and off frequently without cooling. At ND Cooling, our certified technicians use advanced leak detection tools to identify and repair the source, then recharge your system to manufacturer specifications. Refrigerant leaks are serious issues that require professional attention immediately.
3. Frozen Evaporator Coils
If the evaporator coils become frozen or iced over, the AC unit will not be able to absorb the heat effectively. This is normally caused when there is a blockage of air flow through the evaporator coil by a dirty filter, low levels of refrigerant or the wrong setting on the thermostat. If you have iced over your indoor unit or there is water pooling around the indoor unit, please turn off the system and call ND Cooling for assistance. Continuing to run your AC system may cause irreversible damage to the compressor (one of the most expensive repairs). Taking prompt action can help prevent thousands in potential damage costs.
4. Outdoor Unit Blockages
Your outdoor condenser unit releases heat absorbed from your home. If it’s caked with dirt, leaves, grass clippings, or other debris, it cannot expel heat properly, causing your system to overheat and fail. We recommend keeping at least 2 feet of clearance around your unit and scheduling annual professional cleaning to maintain peak performance. A clean condenser can improve efficiency by up to 15%, reducing your cooling costs significantly.
5. Thermostat Problems
Sometimes the issue isn’t with your AC unit—it’s the thermostat. A faulty thermostat may not communicate properly with your system, preventing it from cooling even when needed. Dead batteries, incorrect settings, or damaged wiring are common culprits. Our team at ND Cooling can diagnose thermostat issues and recommend upgrades to smart thermostats for better control, efficiency, and convenience.
