It is never good news when your air conditioner goes out and many things could be causing the failure. Some of them are easy for you to check out and even correct before calling a professional. Start with the basics and work through this list of tips to determine if there is a simple solution to your lack of cool air.
The Circuit Breaker
Your HVAC system needs electricity to function. Check your breaker panel to see if the breaker is tripped. When you open the panel, you should find one or two breakers labeled for the AC unit or units. The switches on these breakers should be in the active position or pointed toward the box’s center. If the switch is pointed to the outside of the box, slide it in the other direction to reset the breaker. If the breaker is functioning properly it should restore power to your AC units.
If you have a digital thermostat that requires batteries, check the display for the LOW indicator. That lets you know that it needs a new battery. If there is no display, replace the battery and reset the thermostat to activate the air conditioner.
If your thermostat is hard wired to power but has no digital display, it has likely failed. You can replace the thermostat or contact your Blue Ox pro for assistance.
Old Dial Thermostat
If you are still using a dial thermostat, it could be showing signs of wearing out and not be as sensitive as it once was. Turn the temperature setting down a few degrees to see if it activated the AC. Even if this works, it is a short-term fix, and the thermostat should be replaced.
Ice On The Outside Unit
If you find that the outdoor equipment is covered in ice, it is likely to be low refrigerant. Shut the unit down until the ice melts, and it should begin to work again. But this is also just a temporary fix until you can get a Blue Ox Heating And Cooling pro out to check the refrigerant level and correct any issues.
No Air Flow
Your air conditioner needs proper airflow to function. And when it is not getting enough air circulation, a fail-safe will shut the unit off to prevent damage. First, check the outdoor equipment to ensure that it is not covered in leaves, grass, and other debris. If the fins are covered, remove the debris and clean the area before turning the unit back on. The other airflow issue could be as simple as a clogged air filter. Replace the filter and try the unit again.
