AC Doesn’t Start After a Reset- What to Do?

If your air conditioner fails to start after a reset, there may be an underlying problem that requires further attention. In such cases, consider the following troubleshooting steps before calling a professional:

  1. Check Power Supply: Ensure that the power switch or circuit breaker is on, and there are no issues with the electrical outlet.
  2. Inspect Filters: Dirty or clogged filters can prevent airflow and cause the AC to malfunction. Clean or replace them if necessary.
  3. Examine Wiring Connections: Loose or damaged wiring connections can disrupt the AC’s operation. Inspect the wiring and make sure all connections are secure.
  4. Inspect Outdoor Unit: Look for any obstructions or debris around the outdoor unit. Clear away any items that could restrict proper airflow.

If the above steps don’t resolve the issue, it’s best to call a professional HVAC technician to diagnose and repair the problem.

Signs Your AC Unit Needs Repairs

While resetting your air conditioner can address some minor issues, certain signs indicate a need for professional repairs. Look out for the following signs:

  1. Frequent Breakdowns: If your AC frequently malfunctions or requires resetting, it may have underlying issues that need professional attention.
  2. Inadequate Cooling: If your air conditioner is unable to cool your space effectively or maintains inconsistent temperatures, it may require repairs.
  3. Unusual Noises or Odors: Strange noises or odors coming from your air conditioner could be a sign of mechanical problems that necessitate repairs.
  4. Increasing Energy Bills: If you notice a sudden increase in your energy bills without any obvious explanation, your air conditioner might be functioning inefficiently.

When you encounter any of these signs, it’s advisable to contact an experienced HVAC professional to assess and repair your air conditioner.

Other Recommended Maintenance

Now that you know about resetting an air conditioner unit, let’s take a look at a few other areas of recommended maintenance.

One of those is how long an HVAC lasts. Most HVACs last between 10-15 years depending on maintenance but also the climate and chemicals that are used in the home.

Another is water dripping from the AC unit. This is not dangerous, but does mean that something is wrong so it is a good idea to get it checked out before it gets too late.

Lastly, is using exterior paint. Make sure that you only use exterior paint on the outside of the home. If you use it the inside of the home, this can ruin not only your HVAC system because of the chemicals but can also harm you and your family.

When Do I Call a Professional

While resetting your air conditioner can resolve some issues, certain situations call for professional assistance. You should consider calling a professional when:

  1. Lack of Experience: If you are unsure about how to reset your air conditioner or lack experience in handling such tasks, it’s best to seek professional help to avoid causing further damage.
  2. Complex Issues: If troubleshooting steps and resets do not resolve the problem, it indicates a more complex issue that requires professional expertise.
  3. Safety Concerns: If you suspect electrical or mechanical problems that could pose safety risks, it’s crucial to have a professional technician inspect and repair your air conditioner.

Professional HVAC technicians have the knowledge, skills, and equipment to diagnose and fix various air conditioning problems effectively and safely.


Knowing how to reset your air conditioner can be a useful skill when faced with minor issues or performance inefficiencies. However, it is important to recognize the limits of self-maintenance and seek professional assistance when needed.

By understanding the signs that indicate the need for repairs and knowing when to call a professional, you can ensure the long-term functionality and efficiency of your air conditioning system. If you are having issues with your air conditioner, it is a good time to have it looked at and to have a home inspection for other areas that are not functioning well.
