5 HVAC Troubleshooting Tips Every Homeowner Should Know

Whether it’s for your own comfort or to reduce your energy bills, HVAC troubleshooting should be on every homeowner’s radar. You can save serious money by addressing problems before they get out of control, and a little advanced knowledge can help you avoid costly repairs that don’t stop the problem.


Here are five essential HVAC troubleshooting tips every homeowner should know:

1) Check that your filters are clean/replaced as needed

A dirty air filter can increase your home’s indoor temperature. Cleaning it can give you an idea of any other problems that may be affecting your air conditioning or heating system. Dirty filters can also lead to high energy bills because they reduce the amount of energy that goes through the AC or heat pumps.

The whole HVAC system needs to be cleaned at least once a year. But if you’re noticing changing air quality or a strange smell, then it’s time to consider replacing the filter. Before you buy a new filter, check the manufacturer’s instructions to see what size your HVAC system needs.

2) Checking the Thermostat

If your thermostat appears to be inaccurate, it might only be that you’re not using it properly. Follow the manufacturer’s instructions for changing the thermostat settings and make sure it is working properly. If you are experiencing a problem with the thermostat, there are a couple of things that can go wrong.

For instance, there could be an issue with the wiring or a problem with the throw-over switch (it could be defective). The whole idea of a thermostat is to keep your home comfortable by controlling heating and cooling. If the thermostat isn’t working correctly, the system won’t output adequate heat or air conditioning to keep your home at the temperature you set it to.

3) Cleaning Indoor Vents, Ducts, and Registers

These are the places where air meets your body. Unfortunately, dust and debris can build up in these openings, which can make them too small for proper airflow. For example, your vents could be sucking in larger particles that should be filtered out.

If you notice any changes in the way your HVAC system works, it might be time to clean. Dust gets trapped inside ducts and registers and creates a damper air flow; when this happens, the system doesn’t work properly. Air leaks can create drafts that make it difficult to maintain the right temperature or humidity level; these leaks mean that your heating or cooling system isn’t working as efficiently as it should.

Call a professional to help you keep your heating and cooling system in good working order.

4) Check the Circuit Breakers and Power Supply

If you’re not using your AC or heater, then the circuit breakers are in place to shut it off. But if the breaker gets tripped accidentally, it can stress out your system and cause it to malfunction. This can be especially dangerous to your home’s wiring system.

If you’re experiencing any frequent trips on your breaker box, check for loose wires and other devices where dirt and moisture can hide from the airflow of the HVAC system. In addition, have a pro come check for any electrical problems.

5) Clearing Debris from the Outdoor Unit

Air needs to make its way in and out of the outdoor unit. If you find that your outdoor unit is clogged with debris, it’s time to take some cleanup action. You can check for debris by removing the panels or taking a peek through one of the air holes. If you see anything other than air circulating, give it a good cleaning.

Whether you’re getting ready for a heating and cooling system installation or have to troubleshoot an existing system, the best way to keep your HVAC running smoothly is by keeping the indoor and outdoor units clean.

This article highlights five HVAC troubleshooting tips that every homeowner should know.
