11 Common Air Conditioning Mistakes to Avoid This Summer
Table of Contents
Most homes rely on cooling systems during the warmer months, but many homeowners unknowingly fall into habits that reduce efficiency and increase costs. In this guide, Prime Genius Heating & Air highlights the most common air conditioning mistakes and what you can do to keep your system working properly.
Common Air Conditioning Mistake: Installing the Wrong Size System
One of the biggest mistakes is installing an AC unit that’s either too big or too small. A system that’s too large cools the home quickly but doesn’t remove humidity, making the space feel clammy. A system that’s too small will run non-stop trying to keep up and wear itself out faster.
To avoid this, it’s important to properly calculate your home’s cooling needs based on room size, insulation, and how the space is used. A professional assessment can help ensure you get the right system.
Running the AC When No One’s Home
Letting your air conditioner run while no one’s home wastes energy and puts unnecessary strain on the system. Many people leave the AC running all day just to come back to a cool house.
Instead, set the temperature a bit higher before leaving or use a programmable thermostat to control cooling schedules. Keeping unused rooms closed off can also help your system work more efficiently.
Installing the Outdoor Unit in the Wrong Spot
The placement of the outdoor AC unit has a big impact on performance. If it’s in direct sunlight all day, the system will have a harder time releasing heat and cooling your home.
Ideally, place it in a shaded area with plenty of open space around it. Avoid planting bushes or building walls too close to the unit since these can trap heat and block airflow.
Placing Thermostats or Vents Poorly
Thermostats placed near windows, lamps, or appliances can get false readings. This causes the air conditioner to run longer than necessary. Similarly, vents blocked by furniture or curtains disrupt airflow and reduce efficiency.
Keep thermostats away from heat sources and ensure all vents are open and unobstructed for balanced cooling throughout your home.
Not Using Fans to Help Move Air
Fans are a great way to improve air circulation and make rooms feel cooler. This lets you keep the thermostat set a few degrees higher while still staying comfortable.
Set ceiling fans to spin counterclockwise in summer to push cool air downward. Floor fans and box fans can also help move air through the home.
Leaving Windows or Doors Open
Leaving a window or door open while your AC is running lets cool air escape and brings hot, humid air inside. This forces your system to work harder and longer.
Always keep windows and doors closed during cooling. Check for drafts and seal gaps around doors and windows to prevent energy loss.
Ignoring the Air Filter
A clogged air filter restricts airflow, reduces cooling power, and increases energy use. It also adds stress to your system, potentially leading to breakdowns.
During summer, check your filter every month and replace it when dirty. Homes with pets or heavy dust may need more frequent changes.
Letting the Coils Get Dirty
The condenser and evaporator coils play a key role in removing heat from your home. When covered in dirt, they can’t work efficiently.
Keep the area around your outdoor unit clean and clear of leaves, grass, and debris. A little attention to coil maintenance goes a long way in preserving system performance.
Skipping Routine Maintenance
Like any appliance, your air conditioner needs regular upkeep to run at its best. Ignoring maintenance can lead to poor performance or expensive repairs.
Inspect seals, check for wear and tear on moving parts, and make sure drainage is working properly at the start of each season. These small checks can help avoid big problems later.
Putting Off Professional Service
Some AC problems like refrigerant issues or electrical faults aren’t easy to detect on your own. That’s where a trained HVAC technician comes in.
Annual tune-ups can help catch small problems early and keep your system running efficiently. Regular professional service is usually much cheaper than emergency repairs.
Expecting the AC to Do It All
Your air conditioner is just one part of keeping your home cool. Without extra support, it has to work harder than necessary.
Use blinds or curtains to block out heat from the sun. Avoid using ovens during the hottest parts of the day. Seal air leaks and consider adding insulation to help maintain cooler indoor temperatures.
Final Thoughts
Taking care of your air conditioning system doesn’t need to be complicated. By avoiding these common mistakes, you can save money on energy bills and help your AC run better and last longer.
