AC Not Blowing Cold Air? Here's What to Do
Is your AC not blowing cold air?
During summer, heat waves are common anywhere in Canada. A recent report forecasted a massive heat wave in Kingston, Ontario. The heat can not only be uncomfortable but can also be a huge health hazard for you and your family.
Your AC may not be completely broken, but blowing warm air isn't any better. If you're having AC problems, you need to diagnose the problem immediately.
Here are some reasons why your AC may not be doing its job right and what you can do to beat the heat. Read on to discover more!
1. Problem With Your Evaporator Coil
If you have an AC that is not blowing cold air, you may be dealing with a frozen evaporator coil. The purpose of an evaporator coil is to remove humidity and heat energy, pumping cool air into your house.
A clogged air filter results in insufficient airflow, freezing the evaporator coil. If left alone, the external refrigerant tubing can start to frost over. You can't access the evaporator coil by yourself, so it's best to get an AC repair specialist.
Fixing this can also help reduce AC costs.
2. Rattling Sounds
Your AC compressor is in charge of managing refrigerant flow. If an AC blows hot air and hears rattling sounds, you may have a damaged compressor.
To fix this, you need to replace your dysfunctional engine.
3. Your Refrigerant is Leaking
If your AC isn't blowing cold air, it can be due to a refrigerant leak. A refrigerant is a critical component in keeping an air conditioner in motion. A refrigerant leak can cause the system to run slower or shut down.
An extended exposure can also lead to refrigerant poisoning. Watch out for signs such as ice build-up. Once you confirm or suspect leaks, switch it off and call for air conditioner repair.
4. Clogged Filter or Registers
The best way to prevent AC problems is proper maintenance. However, not everyone has the liberty of free time to take care of everything in the house. The air filter is one part of an AC unit that faces the most neglect.
The air filter accumulates dust, pollen, and lint all year long. If you fail to change this, your AC will start struggling.
Clogged registers can also affect your AC's ventilation system. It can make a room feel warmer than it should.
5. Fan Blades Rotate Slowly
Slow-rotating fan blades result from a faulty motor. The evaporator coils pump cool air inside and need functioning blades.
Check your motor to see if it's working or look for damages. If you have electrical knowledge and experience, you can DIY the problem. However, it's best to ask for expert help to avoid severe damage or accidents.
