Is your air conditioner switched on, but doesn’t appear to be heating? Well, there are a few reasons why this problem may occur. Most of them can be dealt with by contacting an air conditioner repair team.

1. Faulty Thermostat

This is probably the main reason why a system isn’t heating up a home or business. Thermostats need to be calibrated every so often. If the thermostat is not calibrated, or simply doesn’t work, then the air conditioner will be heating up the property to an incorrect temperature. Most of the time, having an air conditioner repair team fix the thermostat will fix the problem. Just make sure that you have the system calibrated in an air conditioner service at least once per year to stop the problem from returning.

2. Faulty Temperature Sensors

Throughout the system, there will be various temperature sensors that will be checking the temperature of the rooms against the thermostat settings. If these are faulty, then the system may respond as though the rooms have already reached temperature and thus require no more heat. An expert technician can check the sensors for you.

3. Broken Fans

In an air conditioning system, it is the job of the fans to blow the warm air. If the fans are broken, they will not be able to blow the air around as effectively, which can cause inconsistent heating.

Most broken fans are broken due to a lack of proper service. They get clogged with dust and debris, and the bearings eventually fail. If your fans are broken, then they will need to be replaced.

4. The Ducts Are Broken

Over time, the ducts of the system can get damaged. This means that they may become misaligned, or they will have small tears. This can cause warm air to escape. If the problem is particularly serious, then warm air may not be able to reach certain rooms in your property. This will either stop them from heating up, or they will not heat up as effectively as other rooms.

5. Clogged Air Ducts

This may not completely stop heating your home, but clogged air ducts can cause heating issues. If you do not have your system regularly serviced, then the dust will clog up the air filters around your property, and this can cause inconsistent heating. It can also increase your energy bills. Most of the time, cleaning the clogged ducts and filters will deal with the problem.

6. Broken Heating Elements

This is a rare problem, but it can happen. The air conditioners have a heating element that will heat up the air. If this heating element is broken, the system may continue to run, but it will not be producing warm air. If cold air is blowing into a room, despite the thermostat working correctly, then a broken heating element could be the problem.
