You may find yourself surprised by the fact that your heating and cooling bills suddenly comprise half or even more of your utility expenses. If so, it might be best that you check your air conditioning’s efficiency. And if ever you notice that it is no longer cost-effective, worry not, since there are various simple, zero-cost methods that you can apply to make it more efficient.

#1: Clear the Drain Line

Check the indoor cooling coil, and you’ll find a drain mounted above a furnace in your basement. If you would like to clear it, just flush a cup of chlorine bleach down the drain, then rinse with a gallon of water. By doing so, it stays clear for at least a season. Ultimately, clearing the drain will prevent your basement, if the drain is blocked, from taking on water.

#2: Clean the Outdoor Condenser Unit

The outdoor unit of your AC will become more efficient if it is clean and free of debris. All you should be doing is surface cleaning, and you can leave any in-depth cleaning to a professional. Maybe you would like to find skilled technicians such as those from theĀ air conditioning service in Los Angeles.

#3: Increase the Thermostat

You can move up the temperature by about three to five degrees, which can help reduce your expenses. As an example, you can keep it down during the winter or up when it’s summer. It is much better if you have a programmable thermostat since it would adjust the temperature automatically, at different times every day and even when you are not at home.

#4: Keep Curtains and Blinds Closed

Keeping curtains and blinds closed, particularly in the day can help block out direct sun rays from hitting the windows in your home. By doing so, you can minimize the heat that warms your home, which reduces the output provided by the air conditioning system. Although it is quite a simple solution, it helps you save up on those utility bills.

#5: Keep Heat-Producing Appliances Away From the Thermostat

Heat is given off by appliances, which may trick the thermostat into increasing the cooling output, leading to increased energy costs. Thus, you should keep any heat-producing appliances away from the thermostat, so that the system will not work harder than it has to.

#6: Vacuum Indoor Vents

To maintain steady airflow, you should vacuum dust and debris that might block the indoor supply vents. It also helps to keep away items such as blinds, furniture, and other objects from blocking your vents. It is quite simple, yet people often forget to do this, so remind yourself to vacuum the indoor vents regularly.


There are at list six things you can do to make your air conditioning more cost-efficient. These include clearing the drain line, cleaning the outdoor condenser unit, increasing the thermostat, keeping curtains and blinds closed, keeping heat-producing appliances away from the thermostat, and vacuuming indoor vents. You should perform them regularly so that you can spare yourself from unnecessary costs.
