How to Troubleshoot Common HVAC Issues: A Garrett Heating and Cooling Guide Nov 29, 2025

When your HVAC system is on the fritz, it can feel like the world is collapsing in a sweltering heap or a chilly void. As leaders in climate control solutions, Garrett Heating and Cooling understands the frustration that accompanies these all-too-common scenarios. While a call to the professionals is often your best bet, there are a few troubleshooting steps you can undertake first.

Start by assessing the power source. Ensure that your HVAC unit is plugged in and the circuit breaker hasn’t tripped. It might seem too basic, but in many cases, power supply issues are the culprit. Once you've confirmed the system is receiving power, check your thermostat settings. Make sure it's set to "cool" or "heat" depending on your needs, and ensure the target temperature is set correctly. Sometimes, the simplest solutions are overlooked.

Next, consider the air filter. A clogged air filter might seem innocuous, but it can severely impede your system's efficiency. An obstructed airflow can cause your HVAC system to work overtime, leading to potential system shutdowns or uneven heating and cooling. It's recommended to replace or clean your air filter every one to three months, depending on usage and the environment. Keeping filters fresh not only ensures efficient operation but also improves air quality in your home.

If your system is running but not effectively heating or cooling, inspect the air vents. Blocked or closed vents can disrupt airflow, leading to discomfort in your home and unnecessary strain on the unit. Ensure all vents are open and unobstructed. Additionally, check for signs of leaks or damage to your ductwork, as these can dissipate the conditioned air before it reaches its destination.

Still experiencing HVAC issues? Consider inspecting the outdoor unit. Debris, such as leaves or twigs, can accumulate around your exterior unit, obstructing airflow and hindering performance. Gently clear away any debris and ensure the area surrounding the unit is free from clutter. Be cautious, though; if the outdoor unit is caked with grime or ice, it might require professional cleaning or servicing.

For systems struggling to maintain consistent temperatures, a refrigerant problem could be at play. If you notice the unit is not cooling effectively or there's icing on or around the coils, the refrigerant levels might be low. This isn't a fix you can tackle on your own, so reaching out to Garrett Heating and Cooling is crucial. Our technicians are equipped to safely assess and fix refrigerant issues, ensuring your system’s longevity and efficiency.

If none of these common troubleshooting measures resolves the issue, it's wise to enlist professional help. At Garrett Heating and Cooling, we offer comprehensive service checks and maintenance plans to keep your system running smoothly. Regular maintenance not only extends the life of your unit but also helps avoid unexpected breakdowns.

Concluding, while some HVAC issues can be resolved with a little elbow grease and know-how, others require the expertise of a seasoned technician. Proper maintenance and timely intervention are the keys to a comfortable home.
