Understanding Your HVAC System
Understanding your HVAC (heating, ventilation, and air conditioning) system is essential for ensuring home comfort and efficiency.
Components of an HVAC System
Heating Unit – The heating unit, often a furnace or heat pump, warms your home. Furnaces generate heat through fuel combustion (natural gas, oil, or electricity), distributing it throughout the house. Heat pumps transfer heat from the outside air or ground into your home, offering an energy-efficient heating solution.
Cooling Unit – The cooling unit, typically an air conditioner, cools your home by removing heat from the indoor air. This involves refrigerant cycling through coils, absorbing heat from inside and releasing it outside, resulting in a cooler indoor environment during hot weather.
Air Ducts – Air ducts distribute heated or cooled air throughout your home. Properly maintained ducts ensure efficient airflow and good indoor air quality, preventing energy loss and uneven heating or cooling.
How HVAC Systems Work
HVAC systems balance heating, cooling, and ventilation to ensure a comfortable indoor climate. In heating mode, the system’s thermostat detects the need for warmth and activates the heating unit. Warm air is then circulated through the air ducts. In cooling mode, the thermostat signals the cooling unit to start, and the air conditioner removes heat from the indoor air, distributing cooled air via the ductwork. Ventilation, an ongoing process, ensures a continuous supply of fresh air, reducing indoor pollutants and maintaining air quality.

As the weather cools in the fall, inspect the heat exchanger for cracks or damage, which can lead to carbon monoxide leaks. It’s also a good time to test carbon monoxide detectors to ensure they are working correctly and can alert you to any dangerous gas buildup.
Winter Maintenance
Check your home’s insulation in winter to help your HVAC system maintain a consistent indoor temperature without overworking. Test the ignition system to ensure your heating unit starts reliably during the coldest months.
DIY Troubleshooting Tips
When your HVAC system isn’t performing as expected, you can try several DIY troubleshooting tips before calling an HVAC technician. If your HVAC isn’t cooling, check the thermostat settings to ensure it’s set to “cool” and the temperature is lower than the current room temperature. Also, inspect the air filter for dirt and debris, which can block airflow and reduce cooling efficiency.
If your AC unit isn’t heating, make sure the thermostat is set to “heat” and the temperature is higher than the room temperature. Check the pilot light or ignition system for issues and ensure the circuit breaker hasn’t tripped.
If you’re hearing unusual noises, such as banging, clanging, or squealing, it could indicate loose or worn-out components. Inspect the fan blades, belts, and motors for any signs of damage or looseness. Poor airflow can result from dirty air filters, blocked vents, or issues within the ductwork.
