Thermostat Issues

One of the possible reasons why an AC will not turn on is an issue with the thermostat. If it has been set too low or the batteries have run out, this can prevent the unit from activating.

Blown Fuses

Electrical Issues

Check the Thermostat

The first step is to make sure your thermostat isn’t set too low or that the batteries in the unit haven’t run out. Additionally, check for any signs of damage to the wires and connections.

Check the Circuit Breaker

Your AC may shut off if the circuit breaker trips. To avoid this, inspect for obstructions that can cause damage to your unit, such as rodents or debris.

Warning Signs That Your AC Needs Repairs

To help avoid AC issues in the future, here are some warning signs to watch out for that may indicate your AC needs repairs:

Weak Airflow

If your AC is blowing weak or no air at all, this could be a sign of a problem. You should consider having it checked by a professional.

Warm Air 

If you notice the air coming from your vents isn’t as cold as usual, this could indicate issues with your compressor or even leaks in the ductwork.

Strange Noises

Strange sounds coming from your AC system could signify an issue that needs to be addressed immediately. 

Foul Odors

Your HVAC unit is designed to circulate fresh air throughout your home. But if you detect unpleasant odors, then there might be something wrong with the system. 

High Humidity

High humidity inside can lead to condensation problems, which can damage walls and other surfaces around the house when not dealt with promptly. 

High Energy Bills

Increased energy bills are often associated with an inefficient system caused by dirt build-up on filter screens or faulty parts that need attention.  

Short Cycling

This occurs when the system starts cooling down, then stops before it reaches its set temperature point and cycles back on again. It usually results in inadequate cooling power, especially if the system doesn’t receive regular maintenance services, such as coil cleaning and AC filter replacement. 

Leaks 

Leaks of any kind should never go unaddressed, especially those related to liquids entering into electrical components. If left unchecked, these can result in burning out motors and other expensive repair costs. 

The goal of troubleshooting these AC issues is to restore proper cooling and save you money. When attempting to identify the underlying source, it is essential to start with basic solutions, such as checking thermostat settings and ensuring that all connections are secure, before venturing into more complex repairs. Nevertheless, while it may be tempting to attempt a DIY fix, doing so could end up costing you dearly in terms of time, energy bills and repairs if done incorrectly.
