HVAC Troubleshooting Tips That Every Homeowner Must Know

It is essential to stay warm when temperatures outside are below freezing. Keeping your home cool in the summer is also important. Most people take their HVAC systems for granted until something goes wrong. Your heating and cooling system works tirelessly, no matter the season, to keep your home at a comfortable temperature.

If you fail to use your HVAC system correctly, it can lead to a lot of trouble. This is especially true during the summer when temperatures rise too high and in the winter when temperatures drop abnormally. You should know some basic troubleshooting techniques that you can use when your AC system develops faults.

Replace your HVAC filters.

Clogged filters, old or dirty filters, and unclean filters are all significant factors in leakage, as well as poor HVAC performance. The first step in troubleshooting is to replace and check air filters. Filters that are clogged up or blocked force the system to work more efficiently in order to achieve the desired results.

This causes the HVAC system to degrade and consume a large amount of energy, reducing its lifespan. Replace the filters after every 90 days. After a month, if the filters are ineffective and worn out most of the time, you should replace them.

Check for a loose connection on your thermostat.

The thermostat is often to blame for HVAC problems, even though it may seem like a simple fix. If your thermostat is battery-operated, check to see if the batteries are still working.

If your thermostat is electrical, check for loose connections. If your HVAC system does not turn on, always check the thermostat.

Check the unit from the outside.

You’ll likely miss the external unit when evaluating your HVAC. This component is important because it acts as a hub for airflow in your home.

Debris, such as branches and leaves, could get stuck in the unit and cause damage. Removing debris from the unit and the area around it will make the system run more efficiently.

Reset your Circuit Breaker

You may be lucky and only need to turn a knob to fix your HVAC problems. If your HVAC system is not working properly, you will need to reset the breaker.

To rule out electrical problems, reset your circuit breaker. Consider hiring a professional if your HVAC system refuses to turn on.

Clean all the ducts and vents.

When your air conditioner circulates the air in your home, dirt, dust, and other foreign particles can get stuck or clog up your vents, air ducts, and registers. This reduces air conditioner performance, lowers indoor air quality, and causes discomfort in your home.

Knowing when to clean vents, registers, and ducts is important. Because vent and duct cleaning is so complex, it’s also a good idea to consult a professional.

Check The Wiring

Wires can be damaged or disconnected at any time. This is more common with outdoor air conditioners because landscaping equipment can damage exposed cables.

Check your system if it won’t work or reboot. Be careful with any exposed or broken wires. They could cause an electric shock.

Clean your entire unit.

It could create a hazard if the area surrounding your unit isn’t cleaned and properly maintained. To avoid a fire, clear the area around the unit. To prevent a blockage, vacuum and clean the area around the unit.

Maintaining a minimum of two feet around the furnace and cleaning it regularly can extend its life. This reduces the risk of needing to replace your furnace and also safety hazards.

Look For Frozen Coils

If your air conditioner is running but not releasing cool air, check the coils for ice. Ice occurs when the condensation that normally forms in the drain pan condenses onto the coils.

Water on the coils can freeze, blocking heat transmission. This will stop the coils from cooling your home. Although frozen air conditioners can be easily repaired, you should call Heating Repair Henderson when this happens more than once.

Schedule maintenance visits

A professional can help you troubleshoot. Regular HVAC maintenance will prevent problems and prolong the life of your HVAC system.

A higher efficiency can result in lower electricity bills and less likelihood of an unplanned repair. Specialists can tell you if your furnace needs to be cleaned or repaired.


You can use a variety of strategies to maintain your HVAC system. These tips can also help you identify problems with your HVAC system. If you don’t know the cause of a problem or the solution is complicated, it is time to consult a professional.
