As seasons change, it becomes increasingly important to maintain the health of your HVAC (Heating, Ventilation, and Air Conditioning) system. Regular checks help prevent major faults, thus avoiding pricey repairs or replacements. Learning how to perform a DIY home HVAC health check helps you to identify minor issues before they become dire situations. Here’s a guide on how to carry out this essential home maintenance operation.
1. Filter Inspection and Replacement:
Start by inspecting the HVAC filter. It’s usually found in the blower compartment of the furnace, but it can also be in return air ducts or in the unit itself. A clogged or dirty filter will restrict the airflow, making your system work harder than necessary and therefore leading to a decrease in its lifespan and efficiency. Consider changing your filter every 30-60 days depending on the usage. If you use a washable filter, ensure to clean it regularly.
2. Air Duct Inspection:
Next, look at the air ducts. Dust and debris can build up in the air ducts over time, reducing the quality of air that circulates around your home. Make sure there are no major blockages. If the ducts seem too dirty, it’s best to hire a professional service to clean them thoroughly to avoid reducing your system’s efficiency and the quality of your indoor air.
3. Outdoor Unit Inspection:
HVAC units typically have an outdoor unit, which can be a heat pump or an air conditioner. Check for any obvious signs of wear or damage. Clear any vegetation or debris from around the unit to ensure it has at least 2 feet clearance for proper airflow. It’s also important to check and straighten the fins on the outdoor unit, as bent fins can restrict airflow.
4. Thermostat Checking:
Check your thermostat to make sure it’s working properly. If it’s a digital one, ensure its batteries are still good. Your HVAC should kick on when you set the temperature lower and should turn off when the home reaches the pre-set temperature. If there are discrepancies, you may need a professional assessment.
5. Checking the Condensate Drain:
Air conditioners create some level of condensation, which is deposed away via a condensate drain. If the drain is blocked, water can back up into your home, potentially causing damage. Therefore, make sure the condensate drain line is clear and clean.
6. Listen and Observe the System:
Finally, simply running your system can reveal potential issues. Listen for unusual sounds when the unit is running, like banging or rattling, which might mean there’s a problem that needs professional attention. Also, look out for any unusual odors that could indicate a mold issue, or even a failed motor.
Remember, these simple checks do not replace professional maintenance work. It is important to schedule annual HVAC maintenance visits from a reliable HVAC company. The professionals can help assess the condition of your system and carry out necessary servicing tasks. However, regular DIY HVAC health checks certainly help you maintain an efficient and robust system while keeping your living environment comfortable and healthy.
By performing these simple checks regularly, you can enhance the lifespan of your HVAC system, improve your home’s air quality, and avoid the inconvenience and expense of major repair or replacement. Therefore, DIY HVAC home health checks are undeniably a must-do part of your home maintenance routine.
