Diagnosis and Solutions for AC Not Reaching Set Temperature

Diagnosis and Solutions for AC Not Reaching Set Temperature
Updated: March 7, 2024

Getting your home comfortable should be as easy as setting the thermostat to your desired temperature and relaxing. However, it can be more complicated. If your thermostat is not reaching the set temperature and not cooling your home correctly, there could be a few different reasons. As a full-service HVAC company, AccuTemp is experienced in diagnosing and repairing air conditioning problems, so let’s explore some of the issues you could be facing. 

Why Does My Thermostat Setting Not Match My Home’s Temperature?

If you’ve noticed that the temperature in your home isn’t reaching the thermostat setting you have set, there could be many potential causes. This can be an issue for both comfort levels and energy efficiency. From a faulty thermostat to a dirty air filter, these are the most common reasons why your AC may not reach its set temperature.

Not Calibrated Correctly

Your thermostat needs to be calibrated, and if it is incorrectly calibrated, it could cause a difference in temperature between its setting and the actual home temperature. The thermostat may need to be calibrated if it is new, if you have experienced a recent power outage, or if a digital thermostat setting is incorrect. 

Dirty Thermostat

One possible reason your AC is not reaching the set temperature is that the thermostat could be dirty. If dirt, dust, or other debris has accumulated within the thermostat box, it can cause the wires to heat up or other issues. Thermostats are cleaned during routine HVAC maintenance to help prevent this from happening. 

Dirty Air Filter

Air intake is essential for an air conditioner to cycle correctly, so you will run into different issues if an air filter is dirty or clogged. For instance, reduced airflow makes it difficult for the system to run efficiently and cool the air. 

Old, Broken, or Misaligned Thermostat

Sometimes the thermostat not reaching the set temperature results from wear and tear or age. If the thermostat has become misaligned or crooked over the years or has broken components, it can cause 

Exposed to the Sun

Thermostats located in sunlight or near another heat source will be affected because the localized temperature around it is higher than other areas of the room or the home. Heat sources can be particularly problematic if your thermostat was calibrated when it was dark or cloudy and the sun was not shining, affecting the temperature. 

HVAC System is too Small

If your HVAC system is not the right size for your home, it can run perfectly but not have enough output to cool your home adequately. The unit’s size could be the issue if your AC is running continuously but not cooling the house, especially on hot days. Another problem is that it will cause your electricity bill to rise as you use more energy. Discussing your situation and assessing the HVAC unit and your home by a professional can help determine if you need a new unit. 

Circuit Breaker Tripped

If your AC unit has tripped the circuit breaker, try resetting it. However, if the breaker trips again, do not turn it back on, as there is a chance you could cause damage to the AC system. Electrical problems like these should be addressed by trusted professionals.

The Secret to a Cool Home: Hiring an HVAC Technician for A/C Issues

If you’re someone who values the comfort of their home, you know how important it is to keep your air conditioning system running smoothly. The key to achieving this is by hiring a professional HVAC technician who can diagnose and resolve any issues that arise. Rather than attempting to fix problems yourself, which can lead to further complications, seeking the services of a professional ensures that you get the right diagnosis and safe and effective resolutions.
