New HVAC units are expensive, so if your unit is getting older, there are things you can do to make it last longer. This will also ensure your air conditioning continues running to keep the inside of your home cool during the hot summer months. Below are three tips to get you started.
Check the Outside Unit
Go outside and look at the unit. If you see any type of debris around the unit then you need to remove it. This is because debris will block the vents, which will prevent airflow into your home. This will also eventually cause problems inside the unit.
Many things can get built up against the unit. For example, when you mow, grass will blow up against it. During the fall months, leaves can easily build up against the unit also. If you have bushes planted close to the unit, consider moving them further away. This is because leaves or flowers can drop from the bushes too close to your unit.
Check the Fan Blades
While you are outside look at the fan, which is inside where the vent is located. The fan has blades that need to be completely straight. If the blades are bent at all this will also cause less airflow into your home. The fan is also important as it keeps the inside of your unit cool, such as the condenser and evaporator coils.
If you do see bent blades, you can straighten them on your own. You can do this by purchasing a fan comb, which you can find at home improvement stores.
Have the Unit Maintained
One of the most important things you can do is to hire an HVAC contractor to maintain the air conditioning unit. This will ensure that everything is done properly. The contractor will check the inside components. These components include the evaporator coils, the fan, the condenser unit, and more. The contractor will also check the wiring inside the unit. If they notice any wiring that is loose, they will tighten it up. If they see any wiring that looks like it is deteriorating, they will replace the wiring.
The contractor will also check the thermometer inside your home. If you have an older thermometer the contractor will likely suggest that you replace it with a new one.
Talk to your air conditioning maintenance contractor about this information and they can give you many more details. The contractor can also give you tips to help your air conditioning unit to last longer.
