Installing Your New AC: 4 Common Mistakes Technicians Make

Whether you’re buying your first AC unit or replacing an old one, it’s essential to be extra cautious about your purchase. This is because complications with its installation can lead to expensive headaches in the future. Additionally, you won’t enjoy the benefits of a more advanced cooling system if its parts aren’t working properly. This is why you need to be on the lookout for installation mistakes.

Monitoring Your AC Technician’s Installation Procedures

Hiring an HVAC technician is necessary to rig your new AC unit to your home. This is because an AC unit requires the technical expertise of connecting your AC system’s different interior and exterior components. While you should typically trust the contractors you hire, that doesn’t mean they will give you their guaranteed quality service.

Complications in your unit’s performance should be shouldered and repaired by your AC technician if they’re the ones at fault for it. For this reason, you shouldn’t be liable for their installation mistakes. Thankfully, you can monitor their performance to see if they’re giving you the right value of service for your money.

Before handing your new AC unit over to your technician, here are four installation mistakes you should watch out for:

1. Improper Placement of Air Conditioner

An air conditioner needs to be installed in the right position to optimize energy efficiency. Otherwise, your unit will be at risk of bringing out faster just to achieve minimal input. Besides its placements, check your technician if they’re installing it slightly backward. This will ensure that drainage and ventilation will flow properly.

Keep in mind that the best placement of your air conditioner will depend on its type. Because of this, consult with your technician if you bought the right unit for your room’s needs.

2. Improper Placement of Thermostat

Besides the air conditioner itself, the thermostat must be in the right location for accurate temperature regulation. If it’s anywhere near heat-generating devices like other appliances or lighting fixtures, you’ll have an improper reading of indoor temperatures. This is why it’s necessary to check the proper location of your thermostat to follow the adequate temperature adjustments through your AC unit.

3. Lack of Insulation

For a window AC unit, it’s vital to add padding to the open areas between the top and bottom window panes with insulating foam. On the other hand, split air conditioners need to connect with the right size ducts for proper load circulation of indoor air quality. Without the right insulation in these areas, your AC unit can experience early equipment failure.

4. Lack of Unit Inspection

Before installing your AC unit, the technicians should first detect potential leaks in its ducts and other components. The risk of a coolant leak won’t just minimize performance but also compromise your household’s safety. Even if you’re installing a brand new unit, your technicians should still give it a thorough inspection to see if you’ll need a replacement.


The root of all these potential mistakes during installation is an unreliable HVAC contractor. If you hire the wrong AC unit technician to install your unit, you’re more likely to be on the lookout for errors. For this reason, it’s important to trust only the best of the best when it comes to your important purchases, especially for a brand new HVAC system.
