How to Improve Your Air Conditioner’s Efficiency During Excessive Heat

We all know that the primary aim of an air conditioning system is to control the temperature of the indoor environment. These environments include our homes, offices, or recreational facilities such as restaurants and gyms. The coordination between the furnace, the thermostat, and the AC needs to be seamless for it to be effective.


However, changes in environmental conditions, such as increased heat, can influence the system’s effectiveness, especially when talking about the heat in Southern California. But there are guidelines that you can observe and increase the efficiency of the AC immensely.

AC Unit Inspection & Repair

Clean Outdoor Condenser Unit

The quality of the air reaching the indoor environment highly depends on your AC unit’s status located outside. This is because the air that is blown to the furnace must pass through it. Therefore, to ensure that you are getting clean air in your home, make efforts to clean the air conditioner’s condenser coil. California is very susceptible to a lot of dust and sand blowing into our homes.


Washing the unit is straightforward. You will need a hose with sufficient water, a scrubbing brush, and maybe some detergent. Another critical thing to keep in mind is cleaning it from the inside out and not vice versa.

Vacuum Indoor Vents and Keep them Unblocked

Dust trapped in the vents can add toxins and harmful fumigants to the quality of air being blown inside the house. Thus, to ensure clean air from the conditioning unit, you need to keep the vents clean.

This can be done by vacuuming the indoor vents or using brushes for areas the vacuum can’t reach. Additionally, cleaning the ducts might not be an effective strategy when using the same old furnace filter. That’s why it’s advisable to replace it over time.

Increase Your Thermostat By A Few Degrees

Your thermostat is responsible for signaling the entire conditioning system when it is time to cool or heat the air. When heat spikes up here in California, you want to ensure that your thermostat reading is high enough to account for the high temperatures. You need to ensure that the thermostat readings are in a similar range (10-20 degrees) as the temperature outside, or the system will work too hard to regulate the temperature.

Keep Heat Producing Appliances Away from Your Thermostat

Since the thermostat is set to detect heat changes, it will tend to signal that air needs to be cooled down when appliances are close to it. This act will force the system to work hard then it’s meant to, and in return, cost you money. Ensure those heat appliances such as lamps are kept away from the thermostat. It is recommended to install the thermostat at least 4 feet above the floor.

Keep Curtains and Blinds Closed During the Day

Remember, all we are trying to accomplish here is to make the system consume less energy and work efficiently, even during extreme heat conditions. Curtains and blinds are an excellent way to ensure that direct heat from the sun does not overheat the indoor environment. In effect, this will prevent the thermostat from signaling cooling.

Clear Your Drain Line

The condensates from the air conditioner go through a piping system called the drain line to the disposal unit. The drain line will get clogged from time to time due to factors such as water impurities and debris. This clogging will cause ineffective disposal of the condensate, which can lead to AC cuts offs. Washing the drain is easy and quick. All you do is separate the PVC pipes and use a garden hose pipe to blast whatever is blocking it out.

There are several ways to increase the efficiency of your home’s air conditioner and, in return, prolong the life of your unit. One of our expert HVAC technicians can go over your options with you.

Customer Reviews

Called Absolute for my 81 year old landlord in the height of Summer heat. Scott came out to inspect the old beast of an AC and found many issues. He took the time to educate us, note everything, photograph it and provide several recommendations...and my stubborn landlord has done nothing LOL. A couple months later we asked that Scott come back out and he was there that same day.

I contacted Absolute Airflow to check my mother's AC, as it was not getting cold. The tech (Scott) arrived earlier than his scheduled time, and was very knowledgeable, professional, and most of very personable with my mother in letting her know that the issue was. Superb customer service Scott and thank you Absolute Airflow! I highly recommend Absolute Airflow.
