Here’s How to Troubleshoot Your A/C

Here's How to Troubleshoot Your A/CYour air conditioner is a complex system of motorized parts, electrical components, refrigerant, fans, and more. If one part is too dirty, out of whack, or has simply gone kaput, your A/C won’t operate efficiently or, perhaps, it won’t work at all. Try these troubleshooting tips before you call your HVAC contractor.

Unit Doesn’t Run

The first component to check if your A/C isn’t running at all is the thermostat. Make sure it hasn’t been turned to HEAT accidentally. Adjust the temperature five degrees below the displayed temperature. If your A/C still doesn’t turn on, look inside the circuit box to see if a breaker has tripped.

Unit Runs but Not Cooling

It can be frustrating and perplexing when your A/C is running but it’s not blowing out cool air from the vents. There may be dirty components or obstructions that are making your A/C work too hard and unable to keep up with the cooling load.

Journey outdoors and take a look at the unit next to your home (i.e. in a split-system A/C). Remove any obstructions to airflow, such as tall grass and debris. If the condenser coil inside the unit doesn’t receive ample airflow, it won’t be able to cool.

The condenser itself could be dirty enough to block heat transfer — especially if you haven’t scheduled professional maintenance this year. Use a can of spray-on foaming cleaner. Let it soak in according to the instructions and spray off with a garden hose. Make sure power is turned off at the thermostat and circuit breaker.

Professional preventive maintenance is essential for keeping your A/C running efficiently. This saves you energy, reduces system wear, and keeps your San Marcos home comfortable until summer’s end. Moreover, regular service helps prevent expensive and unnecessary malfunctions, which always seem to occur at the hottest and most inopportune times of the year.

Dealing with Common Furnace Issues? Use these Tips

Dealing with Common Furnace Issues? Use these TipsNow that you’re using your furnace on a regular basis, there’s a small chance that you may run into a few trouble spots during its operation. Fortunately, it’s easy to troubleshoot many of these issues on your own. The following highlights a few of these common furnace issues and how you can successfully troubleshoot and even repair them.

  • If it produces no heat – Make sure the thermostat is actually set to “heat.” If that doesn’t work, try moving the thermostat setting up or down a few degrees. Don’t forget to check the circuit breaker and the pilot, as well as the control valve for the furnace’s fuel supply.
  • If it doesn’t produce enough heat – Check the air filter and if it’s clogged, replace it with a fresh one. If that doesn’t work, have your HVAC technician check and readjust the burners.
  • If it turns on and off too frequently – Check and adjust the thermostat heat anticipator, if necessary. You might also want to check the blower motor for proper lubrication and belt tension.
  • If the blower fan does not turn off – Make sure the fan isn’t set to run continuously. If the thermostat has no fan setting, check for a faulty fan limit control switch.
  • If the pilot light goes out – There are many causes that could result in a blown-out pilot light. Check the immediate area for strong drafts. Also, check the gas tube for signs of dirt and debris. You’ll also want to make sure the thermocouple is working properly.
