There are many ways to make your HVAC system more efficient—AC repair is one of them. That’s why it’s best to call a professional to fix issues as soon as possible. Wear and tear or a faulty component can strain the unit and cause it to use more energy. Also, more costly problems can occur and the system’s life expectancy may be reduced.

However, your HVAC system should be more energy efficient and reliable after an AC repair company addresses the following issues:

• Dirty Filters: The air filter is the first place to look if your AC is working less efficiently. A clogged filter can reduce airflow so much it causes the coil to freeze. Replacing the filter is the easiest task; you don’t need a professional to do it. However, a technician will check the filter and replace it if necessary while servicing the unit. 
• Frozen Evaporator Coil: When an evaporator coil freezes, it cannot remove heat effectively. Reduced heat transfer forces the system to work harder and use more energy. While addressing other issues can prevent the coil from freezing again, the evaporator coil must be thoroughly evaluated. Melting the ice is just one step. The coil may need to be repaired or replaced to eliminate issues that affect efficiency, such as a refrigerant leak, corrosion, or a stubborn layer of dirt.
• Damaged Fan Motor: A malfunctioning or broken fan motor can cause the fan to turn too slowly or stop working. The blower fan moves air over the evaporator coil and allows it to be distributed throughout your home. Therefore, a fan motor issue will significantly impact energy efficiency. An AC repair technician can replace the part to restore normal airflow and the system’s peak efficiency.
• Faulty Thermostat: The thermostat controls your AC system by sending the right signals at the right times. If it malfunctions or has faulty wiring, the air conditioner may short cycle, which can reduce energy efficiency. Your home may never reach the right temperature, so comfort will also be affected. An HVAC technician can repair the wiring or suggest installing a digital, programmable, or smart thermostat with features geared toward improving efficiency.
• Leaking Air Ducts: Central AC systems use ductwork to distribute conditioned air properly. If an air duct has a hole, crack, tear, loose connection, or other issue causing air to leak, the unit will not run efficiently. An HVAC professional can provide duct sealing and repair to address the issue. 
• Clean and Repair Vents: Vents are an important part of your air conditioning system. If they’re covered by clothing, furniture, or artwork, airflow is restricted. You can resolve the issue by unblocking vents and making sure they’re open. Cleaning them is important too. If you have trouble cleaning a vent, it has a significant amount of mold, or it’s stuck in a closed position, call a professional for help. Also, don’t close vents in rooms that aren’t being used.

Other Ways to Improve HVAC Efficiency

Even if your AC doesn’t need repairs, some issues can reduce its efficiency. You can help improve energy efficiency with the following steps:

• Raise the thermostat a few degrees when you’re not home.
• Avoid resetting the thermostat often; it causes the AC to cycle more frequently.
• Add or improve insulation and install weatherstripping around doors and windows.
• Install the condenser in a cool, shaded area and maintain clearance on all sides.
• Clean leaves, dirt, and debris from the condenser unit to maintain airflow.
• Consider setting up a zoning system for temperature control in each room.
• Turn off heat-generating electronics when not using them.

Schedule Regular AC Maintenance

The spring is the best time to schedule annual AC maintenance. A technician will perform an inspection and tune-up. Routine service can prevent expensive repairs, but it goes a long way in saving on energy costs over the long term. Cleaning the inside of units, tightening belts and electrical connections, and lubricating moving parts are just a few tasks that can allow the system to cool your home more effectively while using less power.
