7 Common AC Installation Mistakes and How to Avoid Them

Almost 90% of American homes have an air conditioning system fitted in them. These systems are vital for keeping your home cool and comfortable in the summer months. They also help to improve the air quality in your home all year round. 

However, installing and maintaining your HVAC unit is essential if it is going to run efficiently. In fact, outdated or inefficient systems and AC installation mistakes can increase your energy bills by 20-40%.

Want to know how to install an air conditioner system in your home without making mistakes? Well, you're in the right place! Read on to find out seven common AC installation mistakes and our tips for troubleshooting them.

1. Choosing the Wrong Sized AC Unit

Choosing the right size of air conditioning unit for your house is crucial if it's going to run efficiently. Units that are too big run the risk of short-cycling. However, units that are too small will have to overwork in order to keep your home cool. 

This depends on the size of the area you are planning on cooling. To do this, multiply the width of the room in feet by the length of the room in feet.

Then multiply this number by 25 as you need 25 BTU per square foot for effective cooling. This will leave you with the minimum cooling capacity you need.

2. Using a Poor Quality Drainage System

While your AC unit is running, it generates a lot of moisture and this needs to filter away properly. If it doesn't it can lead to leaks and serious water damage to your home. 

This is why have a good drainage system in place for your AC system is vital. This requires: 

  • A well-positioned tray to catch condensation below the coil
  • A clear condensation drain
  • A condensation pump

These three elements also need to be maintained to ensure they work effectively.

3. Not Sealing the Ductwork Properly

Poor sealing can also lead to leakage problems and not just of water. Poorly sealed ducts can allow air to escape your conditioner unit.

To avoid this, make sure you seal your ducts up using a proper sealant. Tape can work as a temporary solution if you notice a gap but small amounts of air can still escape this. If your unit is going to keep running efficiently, you should seal this up using the proper equipment as soon as possible.

4. Installing Your Thermostat in the Wrong Place

Whether you're using a standard thermostat or smart thermostats, its position matters. This is because your AC unit uses the thermostat to determine how hard it needs to work.

To keep it running smoothly, you should position your thermostat in a well-regulated spot away from any air vents. Ideally, try to position it out of the sun. Putting it in direct sunlight will make it read a higher temperature so your unit will start working harder to counterbalance this.

5. Putting Your Condenser in the Wrong Place

In a similar way, positioning your condenser out of the sun will reduce how hard it has to work. This will reduce how much energy it uses and extend the lifespan of the condenser itself. 

Your condenser also needs plenty of space around it if it is going to take in air easily. Ideally, it should have a two-foot clearance area on all sides. So if you are thinking of putting it in a storage area, think again!

6. Putting Your Vents in the Wrong Place

Proper ventilation is extremely important for your AC unit's efficiency. This allows air to flow steadily through the unit and your vents play a role in this. They draw air in from the room and pass it through your AC unit. 

Placing all of your vents close together will make this less efficient. It is much better for your system, to spread your vents out around a room and throughout your home. That way they draw air in evenly. 

Covering up vents also reduces how much air they are able to pull in. Because of this, make sure that you put them in places where they won't be obstructed by furniture and other objects.

7. Using Too Much Refrigerant

Once you have installed your AC system, your refrigerant is the last thing you need to add.

This helps to cool the temperature of the air in your home by absorbing the warm air. The refrigerant is then cooled as a liquid before turning back into a low-pressure gas. This allows your system to cool the air in your home as a liquid before releasing it back out as a cooler gas.

However, putting too much refrigerant in your air conditioning system can cause serious issues. This can cause your entire system to malfunction and is a very expensive mistake to correct. 

To avoid doing this, it is important that you familiarize yourself with the instructions for your specific AC unit. These will outline exactly how much refrigerant you should add and when you need to top this up. Follow these instructions to the letter and you can't go wrong!

Avoid These AC Installation Mistakes

Setting up your own air conditioner system can save you a lot of money provided you know what you're doing. It is important to familiarize yourself with the best system for your home to avoid common AC installation mistakes.
