As summer’s last gasp continues, it may find seem like your HVAC settings are set to heat rather than the cool air you still need. Sometimes the problem is mechanical and requires a pro to fix it. There are some problems you can solve yourself by cleaning a few components.
- It may be that the air handler’s fan is set to “on.”If it is, it will run nonstop, even when the air conditioner has shut off. As the fan continues to run, the air will get warmer and warmer until the A/C kicks on again. Avoid this situation by setting the fan to “auto.”
- The outside unit is clogged.Check the condition of the condensing coil in the outside unit. If it’s overly dirty, the refrigerant won’t cool as much, and your home will be warmer. Hose off the coil. If the dirt won’t loosen, use coil cleaner found at home improvement centers.
- There’s a major leak in the ductwork.Chances are, the ducts run through the attic and when there is a large leak, hot air will enter the ducts and warm your home.
