How to Use Air Conditioner Effectively

Whether you have installed a brand new high-efficiency air conditioner, or are running your current model, how you use your air conditioner during hot summer months can change its efficacy and efficiency.

When it becomes too hot and humid outdoors, we are thankful for home air conditioning. With the push of a few buttons, we have cooled air circulating through the home.

But did you know air conditioning was originally invented to remove humidity from indoor air? Cool air was a happy by-product. But since air conditioning doesn’t actually produce cold air, it simply removes warm air and humidity, there are many factors that will contribute to it working too hard, or not at all.

Using your home’s air conditioner and setting the temperature thermostat to ideal settings are great ways to ensure it will last for years to come and create incredible indoor comfort.

Here are some tips on how you can maximize home comfort even in the hottest summer months.

Leave the Air Conditioner Running

The U.S. Department of Energy recommends keeping indoor temperature as close to outdoor temperature as possible. When the thermostat soars to the high 80’s and 90’s, that is not always ideal. However, homeowners can keep the air conditioner running at higher temperatures while away from the home.

It actually takes much longer to remove warm air and “cool” the house down from extreme temperatures. This causes the AC unit to work harder and can lead to leaks, repairs, and early replacement. By setting the thermostat 10 degrees higher when you leave the home, it will help maintain energy efficiency and save on utility cooling costs, while not letting the home become too hot to effectively cool when you need it most.

With a programmable thermostat, you can even set the indoor temperature to begin cooling prior to your return so it will always be comfortable.

Use Fans to Help Circulate Air and Open Windows on Cool Nights

Instead of constantly running the fan on your air conditioning unit, place the fan setting to “auto” and use ceiling fans, or box fans, to circulate and move air throughout the home. Giving the air conditioner fans a rest can extend the life of the system and save it from wear and tear.

Another way to help out your air conditioner is by opening windows in the cooler evenings to give the AC unit a rest. In San Diego, we are lucky that the humidity level is relatively low even in our summer months. Take advantage of cooler evenings so when the heat is unbearable, the A/C will be working perfectly.

Install a Smart Programmable Thermostat

Using a smart programmable thermostat provides control to ensure the air conditioner is always at its most energy efficient setting. With smart thermostats, homeowners can control settings from anywhere with wifi. Imagine being able to adjust the temperature based on real time weather conditions at any time. Before you arrive home, you can lower it to your desired setting, set it higher while you are away, and keep an eye on utility energy costs at all times.

Most programmable thermostats have the capability to create  a complex schedule and can be set and forgotten. But, with a smart thermostat that connects to a smartphone and app, you can adjust at any time. Keep your home cooling efficient, pets and family comfortable, while still controlling the settings, and make adjustments at any time.

Perform Regular Maintenance and Clean the Air Filter

Dirty air filters are one of the most damaging elements in any HVAC system. Clogged air filters cause the unit to work harder, can block airflow, and lead to failures in the motor, compressor, or other components.  

Annual air conditioner tune-ups are important to clean the unit and perform safety checks, as well as ensuring the air filter is changed at least once per year. If you have pets in the home, live in dustier areas such as cities, or near freeways, it is wise to change, or clean them, them every quarter.

Set the Thermostat at the Right Temperature

Home air conditioners remove warm air and humidity creating a “cool” air effect circulating through the home. Efficient systems will provide year-round comfort without affecting the utility bills too greatly. However, homeowners should also be careful at how cool they attempt to set the thermostat.

Air conditioning systems are only designed to “cool” a space by about 20 degrees. If it is 90 degrees outside, a high SEER system can effectively cool the home to about 70, but at a price.

The best way to create home comfort without harming the unit and breaking the bank with high energy bills, is by setting it at a comfortable, but not cold, temperature. According to the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE), the perfect setting lands between 73 and 79 degrees. Our expert specialists say the perfect number is 78.

With the use of indoor fans moving conditioned air throughout the home, and summer clothing, 78 will feel much lower.

Although 78 degrees might seem high, compared to outdoor temperature during summer heatwaves, and natural body temperature, it is the perfect setting.

Additional ways to keep your air conditioning working effectively and remain comfortable include:

– Find ways to introduce shade to the home. Awnings, window coverings, trees, and other shade over windows can help reduce indoor heat.

– Install high-efficiency windows to further help in preventing air loss from escaping and heat from getting inside.

– Ensure the home is properly insulated to keep conditioned air from escaping through poor seals and wasting money on inefficient cooling costs.

– Avoid using stoves and other appliances that produce heat until after the sun goes down.

– Install ceiling fans and ensure they are on the summer settings.

– Replace inefficient air conditioners with high-efficiency systems.

Air conditioners may have been invented for a purpose other than cool cold air, but they are definitely meant to help us maintain indoor air comfort all summer long. But understanding how to use the air conditioning system efficiently is important to saving on energy bills, maintaining perfect temperatures and not causing the unit to work harder than it has to.

The best first step in any efficient system begins with expert preventative maintenance.

Very Satisfied. Michael is always on time, Michael has been doing all of the plumbing related to our remodel. He always does exactly what he commits to do within the estimated cost. He keeps me informed if any wrinkles pop up, and his plumbing skills are excellent as we have had no problems or issues arise after he has left. Very professional! Highly recommend.

What Rick M says about us

We had other companies come out for estimates on what was considered a major job with jackhammers and replacing cast iron pipes under the house… having been stung before, we wanted another estimate just to make sure we were making an informed decision. The prior estimates went up to $21,000!
Bill Howe sent us an amazing veteran plumber, Dashawn and his co- worker Anthony. Dashawn did a thorough check of the problem, explained what he thought was needed … he did a final check and we were able to see for ourselves what was the problem. He recommended a complete cleaning to de-scale the pipes, and not the major work we dreaded. Thanks to his solid analysis and patience in making sure we saw what he saw, the issue was resolved completely, and saved us thousands of unnecessary work. None of the other estimates included the cleaning; only the major repairs. Thanks to Dashawn’s knowledge, professionalism and honesty, we’re Bill Howe customers.

What Carolyn Housman says about us

This was our second excellent experience with Bill Howe. We had a blocked kitchen sink drain 8/5. I was able to get a same day appointment which is AMAZING. Person on phone was very courteous and set me up right away. Tony arrived at the house (called me 30 minutes out so I was able to be ready). He diagnosed the issue (blocked drain, not the garbage compactor) and was able to snake it and ran the water for 10 minutes to be sure the drains were clear. He cleaned up everything and you would not have known he was even there. Thank-you Tony and Bill Howe, you always know how.

Cory was our technician on this job. We had a time sensitive repair issue and Bill Howe understood and assisted with getting the job done quickly.
Cory was on time to start the job and finished it quickly. Upon his leaving our home he’s was courteous, very knowledgeable, explaining what the problem was and how he fixed it. Very good communication and this is the way it’s has always been when we use Bill Howe plumbing.
Great company to work with.
Thanks Cory.

What Bridgett says about us

I am extremely happy with the service we received from Bill Howe Plumbing. We were given an incorrect diagnosis of our main sewer line from another vendor, but Bill Howe’s servicemen came out for a second opinion, correctly diagnosed our problem and resolved our back up issues. We will continue to use Bill Howe for all our future plumbing needs!

Thank you Bill Howe Plumbing.
