Like other machines, most HVAC systems develop technical problems in their lifetime.

However, not every problem with your HVAC system requires your bank account to take a hit.

Your HVAC is bound to develop problems once in a while, but not all problems are major ones.

Before contacting a professional, here are a few troubleshooting tips to try out.

Troubleshooting Tips

Check the thermostat for a loose connection

Often, the thermostat is the cause of most HVAC-related issues as much as it might seem like a very simple fix.

If the thermostat uses batteries, ensure the batteries are not dead and if it is an electric thermostat, check the thermostat for a loose connection.

In any situation where your HVAC system fails to turn on or run, you should check out the thermostat first using the above tips.

The air filter needs a change

Where your air conditioner develops trouble in keeping up with its workload effectively, the root of the problem might be a clogged air filter. 

When you do not change the air filter of your air conditioner for a long while, dust and dirt begin to accumulate and clog the air filter and prevent clean air from blowing through.

This not only pressures the air conditioner to work extra hard for the air to break, but it also traps in pollutants that push through the filter and reduce the air quality indoors.

To prevent the air conditioner from damage and protect your health, change the air filter regularly.

Try resetting your circuit breaker

Sometimes, the solution to your HVAC problems could be as simple as flipping a switch.

If your breaker trips, it would require you to do a minor reset before the HVAC system can function again. 

If this happens to your system, try resetting the circuit breaker to ensure the problem is not an electrical one.

If you don’t have the manual, you can search for them online using the system’s model number.

Consider calling a professional if it doesn’t come on after trying out the above hacks.

Check your ducts for damages

A faulty duct is often the root of the problems of a malfunctioning HVAC system.

On some occasions, you might need to call a professional to repair the ducts, but it depends on the extent of the damage to the ducts.

However, where the damages are small holes and cracks or dirt in ducts, the remedy is as simple as a little taping or vent cleaning. 

Turn off the AC

During summer, if your air conditioner has been turned on for a long time, it is no doubt that some components might freeze in and clog the ventilation.

If the AC does not come on, try turning it off and turning on the fan for a while to dislodge unwanted particles before turning the AC back on.

Make sure your furnace door is closed

Most furnaces have a switch that stops them from operating when the service door is open.

Try opening the service door of the furnace and shut it again.

If you notice your furnace is not producing any heat, ensure everything else is tightly shut before turning on the heater again.

Check the wires

One of the problems of malfunctioning HVAC systems could be wires that have gotten damaged or disconnected.

This can cause the system not to function properly.

In this situation, you can check the wires and protect them from the risk of total damage.

However, make sure not to handle or change open wires by yourself.

Ensure you have power

If you notice your HVAC system is not functioning properly, the next thing to try is to check if the power supply to the unit is intact.

If there’s no power going into the unit, it won’t work.

To do this, check the breaker or fuse panel to be sure nothing is tripped, or turn the thermostat up and down.

Check for frozen coils

If your air conditioner is turned on and is not releasing cool air, check the coils inside for frozen water or ice.

When the water on the coils freeze, it clogs heat transmission, which obstructs the coils from cooling the air.

So, clean out the coils occasionally.
