Summers in Kansas can be extremely hot. When your air conditioner fails to cool your home, your frustration can rise. Homeowners across the region deal with this issue more than they would like. In many cases, the solution is relatively straightforward. It’s essential to understand what can cause your AC to run inefficiently or blow out warm air instead of cool air.
At Everest Heating & Cooling, Plumbing & Rooter in Lansing, KS, we want you to know about the most common reasons why your AC may not cool effectively. Regardless of the cause, we provide prompt air conditioning repairs.
Dirty or Clogged Air Filters
One of the most common causes of air conditioners running but not cooling is a dirty air filter. Filters that become clogged with dust and debris restrict airflow. Your air conditioner may struggle to cool, and ice can build up on the coils.
It’s essential to check your air filter often. If it looks dirty, you need a new one. Most systems require a new filter every one to three months. Changing your filters regularly is one of the easiest ways to ensure your AC runs efficiently and keeps your electric bills as low as possible.
Thermostat Issues
A faulty thermostat can easily throw your system off. If your thermostat is set to the wrong temperature or is malfunctioning, the AC may continue to run without producing cool air.
Ensure your thermostat is on the correct cooling setting. If the screen is blank or unresponsive, you may need to change the batteries. Your thermostat could also need an update or a replacement. We can inspect your thermostat and determine if it needs repair or replacement.
Refrigerant Leaks
Low refrigerant is a more serious repair problem that requires professional intervention. Your air conditioner uses coolant to absorb heat from the air. If there is a leak, your system can no longer cool, even if it runs correctly.
The following are common signs you may notice if you have a refrigerant leak:
- Warm air blowing from the vents
- Hissing or bubbling noises coming from the unit
- Ice on the refrigerant line or evaporator coil
Refilling the refrigerant is never a DIY option. Handling refrigerants requires proper certification and tools. If you suspect a leak, we can schedule an inspection to find the source of the leak, repair it, and recharge your system.
Blocked Condenser Unit
Your outdoor condenser unit plays a critical role in removing heat from your home. When it gets clogged with grass, dirt, or debris, it cannot release heat effectively.
To help air circulate, keep your outdoor unit clean and free from debris. Always turn it off before doing any cleaning. Be careful not to bend the fins or cause any damage during cleaning. It is also essential to keep weeds, grass, and plants trimmed around your outdoor unit to allow proper airflow.
Frozen Evaporator Coils
Frozen coils prevent your air conditioner from functioning correctly. When airflow becomes constricted or refrigerant levels drop, the evaporator coil may get too cold, causing freezing. The frozen coil blocks heat absorption.
Shut off the AC, and allow the coils to thaw completely. A professional inspection can determine why the coils keep freezing, allowing us to make the necessary repairs.
Improperly Sized or Aging System
If your AC is running constantly but never cooling, the system may be too small for your home. It could also be wearing out if it’s over 10 to 15 years old. Older systems gradually lose efficiency as they age and may struggle to meet cooling demands.
If your system is nearing the end of its life span, it’s time to start shopping for a replacement. Upgrading to a new energy-efficient system can save you up to 40% on your cooling costs, according to the U.S. Environmental Protection Agency (EPA).
Ductwork Problems
Leaks or blockages in the ductwork can prevent cool air from reaching certain areas of your home. Even if the air conditioner works fine, damaged ducts waste cooled air and strain your system.
We can inspect your ductwork to identify signs of leaks resulting from wear and tear or damage. Sealing leaks and insulating your ductwork can protect against energy loss and keep your home cooler.
