The Importance Of HVAC System Efficiency

Having the right heating and cooling system in a home or business can have a huge impact on the energy costs associated with HVAC systems. Units that are too large or too small are unable to properly heat or cool a building at maximum efficiency.

What To Do When Temperatures Are Spiking And Your Air Conditioner Isn't Blowing Cold Air

Your home's air conditioning system is your savior when temperatures are miserably hot outside. However, when you turn down the thermostat and the system refuses to blow any cold air, then the HVAC system quickly becomes your most hated home appliance and becomes a potentially expensive problem you now need to fix.

Though a licensed HVAC technician may ultimately be required to repair your system's current issue, there are a few things you can check before you make that call, including the following.

Check the Thermostat

When your home's heating or air conditioning system isn't performing as you expect, then it's important to start the troubleshooting process at the thermostat. This simple device's job is to tell the system when to turn on and off and in what mode to do so—heating or cooling. When it malfunctions or something isn't set correctly, the thermostat is the most likely cause of cooling and heating problems.

If the air conditioning system won't turn on at all, check to make sure the thermostat isn't indicating its battery needs replacement. Sometimes a simple battery replacement will solve a lot of HVAC problems.

If the battery indicator isn't on, then ensure the fan is set to "auto" and the temperature setting is lower than the current temperature in the room.

Check the Electrical Breaker

If the thermostat is set as required but the system still doesn't blow any air, hot or cold, then it's possible it doesn't have any electricity flowing to it. To determine if this is the problem, check the electrical breaker in the panel and make sure it hasn't turned itself off. If it did, then simply flip it back to the "on" position and see if that solves the current issue.

Check the Furnace Filter

If the thermostat and power appear fine, then you should check the condition of the furnace filter. Dirty or clogged filters restrict the airflow into the HVAC system and can cause the air conditioner's coils to freeze. When this happens, the air coming out of your registers will no longer feel cold. Simply swapping the dirty filter for a clean one and letting the coils defrost will solve this problem.

For Additional Assistance

Finally, many air conditioning problems require professional repair. Residential systems are prone to problems with evaporator coil leaks and compressor failures that aren't a DIY repair. So, if you have taken the steps above and the system still won't blow cold air, then it's time to call in an air conditioning repair professional.
