Your HVAC system is important for creating a comfortable and cool environment inside your home as summer temperatures rise. Routine maintenance of your unit is necessary to prolong the life of your HVAC system and improve efficiency. There are a few things you can due to ensure your unit is running safely and efficiently, but annual maintenance from a professional HVAC technician may uncover faulty equipment and safety hazards you may overlook.


Here are a few simple things you can do to ensure your unit is 
running efficiently: 

Check Your Thermostat:
Set your thermostat to 78°F in the summer to stay cool and lower your energy bill. For every degree you increase your thermostat setting during the summer, you can save up to 5% on your energy bill. 

Change Your Air Filters:
Dirty air filters can decrease the life of your unit and increase your energy bill. Change your air filters at the frequency recommended by the filter packaging, which usually suggests every 4-6 weeks. An added bonus: a clean air filter means less dust in your house and less time cleaning!

Keep Your Unit Clear:
Remove debris from the unit. Be sure to trim back plants and foliage to at least 18 inches from the unit. Hose down the outdoor unit if it begins to accumulate dirt. Be sure all indoor vents are not blocked by curtains, rugs or furniture so that air can efficiently cool the home. (11010001)


Below are a few things you can expect to see in a maintenance check of your HVAC system from a professional technician: 

Check Refrigerant Charge:  
Too much or too little refrigerant can cause the system to run less efficiently at a higher cost to you. 

Check Evaporator and Condenser Coils:  
Dirty coils can decrease efficiency and cause your system to run longer, shortening the life of the unit.

Clean and Adjust the Blower:  
As dirt accumulates on the blower fans, airflow is reduced. This can reduce the efficiency of your unit by 15%. Making annual adjustments ensures airflow and comfort.

Tighten Electrical Connections: 
Loose connections can be dangerous and shorten the unit’s life span. The technician will also check to see the unit is using proper voltage and current. 

Lubricate Moving Parts:  
Lack of lubrication on the moving parts can cause the unit to overheat and break down while increasing your energy bill.

Check System Controls:  
The start cycle, operation and shut off of a system should occur in a particular order to operate safely and efficiently.

Inspect the Condensation Drain: 
Properly functioning cooling units will condensate when they run. Typically, that water drains outside the unit and out of the home for indoor units. Over time, sludge and algae can block the pipe causing water damage to your unit and your home, particularly for units located in the attic.
