It is also a good idea to hire an HVAC company to inspect and do any needed maintenance on your system every all and spring. The technician will inspect and clean the wiring mechanism of the HVAC system, which is a little more than the average homeowner should complete by themselves. This article will discuss tips for preventative maintenance on your HVAC system. It is important to keep in mind that you should always take precautionary measures when working with machinery and make sure you are safe when you complete any of these tasks. And remember to leave any of the more complicated jobs to the professionals.


There are certain steps you need to take immediately to insure your HVAC system continues to stay fit and run efficiently. The first thing to do is to buy a better filter for your system. A high-efficiency pleated filter has an electrostatic charge that works like a magnet to grab at the tiniest of particles, including those particles that carry bacteria. A reliable air filter will keep your HVAC system clean and working effectively.

Next, you should check to make sure that there is at least two feet of clearance around your outdoor air conditioning unit and heat pump. This will include removing shrubs that hang over the unit, fallen branches and leaves, etc. It is also important to remember to clear the unit area on a weekly basis during the summer, spring, and fall. Also remember never to close more than 20% of your home’s registers in order to avoid placing unnecessary strains on the HVAC system.


There are also certain tasks you will need to complete on a monthly basis. While most air filters only need replacing every ninety days, you should check it on a monthly basis. If the air filter looks too dark or too clogged, you should go ahead and replace the filter and change it out. Also, if you have pets you should more than likely change the filter every month.

Another monthly task you should keep in mind is to inspect the insulation on the refrigerant lines that lead into the house. If you notice anything out of the ordinary or not working properly and make any repairs that are needed.


There are also annual tasks to complete to keep your HVAC system fit. You should always have a routine maintenance check on your HVAC system. This will insure that your system is running smoothly and any issues are taken care of before they turn into bigger issues. You should also make sure that the outdoor air conditioning unit is on firm or level ground so that they work properly.

You should also pour a mixture of bleach and water down the air conditioner condensate drain in order to prevent any buildup of mold and other debris that can cause damage to your system. Another annual task is to replace the battery in your home’s carbon monoxide detector to insure it is working properly and will detect the proper levels of carbon monoxide.   Some seasonal tasks include turning off the water supply to the furnace humidifier in the summer, replacing the humidifier wick filter, setting the humidistat to 35%-40% relative humidity, and turning on the water supply in the fall.
