1. Choosing the Cheapest Installer
Selecting an air conditioning installer based solely on price can lead to costly consequences. Budget installers often cut corners by:
- Using low-quality components
- Skipping essential safety checks
- Not sizing systems correctly, resulting in poor performance and comfort
- Not following best practice installation procedures, resulting in higher chances of long term issues
- Installing mismatched system components
Quality installation from certified professionals like Smarter Air and Electrical may cost slightly more upfront but delivers significant benefits:
- Proper system configuration for optimal performance
- Extended equipment lifespan through correct installation
- Lower energy bills from correct sizing
- Valid warranty coverage maintained
- Top after sales support
- Compliance with safety regulations
A professional installation prevents common issues such as refrigerant leaks, electrical faults, and poor drainage setup. These problems can lead to system failures, requiring expensive repairs or complete replacement – costs that far exceed the initial savings from choosing a budget installer who may not honour any after sales issues.
2. Incorrect Unit Sizing
Selecting the wrong air conditioning unit size can lead to significant performance issues and unnecessary costs. An undersized unit will:
- Struggle to reach desired temperatures
- Run continuously, increasing energy bills
- Experience excessive wear and tear
- Have a shorter lifespan
An oversized unit creates its own problems:
- Short cycling (frequent on/off)
- Inadequate dehumidification, causing it to be cool, but less comfortable inside
- Higher energy consumption
- Uneven cooling throughout spaces
To determine the right size for your space, you need to consider:
- Room dimensions (length, width, height)
- Window sizes and orientation
- Insulation quality
- Number of occupants
- Heat-generating appliances
- Local climate conditions
At Smarter Air and Electrical, we calculate the precise cooling requirements using industry-standard load calculations to ensure optimal unit sizing for your Brisbane home.
Your outdoor unit needs proper ventilation to function efficiently. Installing it in confined spaces or areas with poor air circulation forces the system to work harder, leading to increased energy costs and potential system damage. Smarter Air and Electrical‘s technicians assess your property’s layout to determine the most effective placement for optimal airflow and system performance.
3. Inadequate Insulation
Proper duct sealing and insulation plays a critical role in your air conditioning system’s performance. Poorly sealed and insulated ductwork can leak up to 30% of conditioned air, resulting in significant energy waste and higher electricity bills.
Inadequate sealing and insulation can lead to:
- Heat Transfer: Unprotected ducts absorb heat from surrounding spaces, warming up your cooled air before it reaches your rooms
- Condensation Issues: Poor insulation leads to moisture buildup, creating ideal conditions for mold growth
- Energy Wastage: Your system works harder to maintain desired temperatures, increasing wear and tear
Smarter Air and Electrical supplies R1.0 insulated duct to suit the Australian Standards and also offers R1.5 and R2.0 duct upgrades for improved efficiency and performance. This specification ensures optimal thermal protection and prevents energy loss through your ductwork system.
A professional inspection can identify insulation gaps and deterioration points in your ductwork, helping maintain your system’s efficiency and reduce operating costs.
4. Neglecting Maintenance
Regular maintenance is crucial for the performance of your air conditioning system. To ensure optimal efficiency, you should schedule professional servicing with Smarter Air and Electrical at least once a year.
Essential maintenance tasks you can perform:
- Clean return air filters every 2-3 months
- Keep outdoor units free from debris and vegetation
- Monitor unusual sounds or odors
Professional maintenance includes:
- Performance & temperature checks
- Electrical connections inspected & tightened
- Inspection inside indoor unit
- Filter cleaning and disinfecting
- Drain cleaning and caustic tablet application
- Airflow check & balancing
A well-maintained system can use as much as 15-20% less energy than a neglected one. With proper care, your air conditioner can last for up to 15 years or more, while without regular maintenance it may only last 5-10 years.
5. Not Considering Electrical Requirements
The electrical specifications of your air conditioning unit are crucial for its performance and safety. If the power demands of your new AC system exceed what the circuit or mains can handle, you may experience:
- Frequent circuit breaker trips
- System damage
- Fire hazards
- Power issues for the household
To avoid these issues, it’s important to have a dedicated circuit with the appropriate amperage rating for your AC unit. Here’s a general guideline for the circuit requirements of split systems:
- 20 amp circuit for smaller units
- 32-40 amp circuit for larger systems
At Smarter Air and Electrical, our professional electricians understand the significance of assessing your home’s electrical capacity before installing an air conditioning system. We will thoroughly evaluate your switchboard and incoming mains to ensure it can support the additional load imposed by the AC unit.
By having a proper electrical setup in place, you can prevent system failures and guarantee that your AC unit operates at its highest efficiency during Brisbane’s scorching summers.
6. Post-Installation Checks That Can Affect Performance
Your new air conditioning system needs to be commissioned correctly to ensure optimal performance. Here’s what you need to verify:
- Static Pressure adjustment: Many makes and models are imported with static pressure settings that are too low to suit Queensland’s tropical weather. If these settings aren’t adjusted on the unit during commissioning, it can lead to significant sweating and condensation issues due to the air in the system being too cold for our high dew point summers.
- Airflow Assessment: Checking each vent and return air grille for proper airflow.
- Sound Level Testing: Checking for unusual noises during operation that might indicate installation issues.
- Drainage System: Verify the condensate drain line is properly connected and flowing
- Control Functions: Test all remote control and app features are working as expected.
At Smarter Air and Electrical, we perform a comprehensive post-installation checklist that includes airflow testing, electrical safety checks, and performance verification. Your system’s efficiency depends on these critical post-installation assessments – skipping them can lead to reduced performance and potential system failures.
7. Setting Temperature Too Low
Setting your target temperature too low can significantly impact your energy bills and system efficiency. The ideal temperature setting for Brisbane homes is 22-24 degrees Celsius during summer.
Here’s what happens when you set your thermostat too low:
- Your AC unit works harder, consuming up to 10% more energy for each degree below 24°C
- System components experience increased wear and tear
- Higher electricity bills due to excessive power consumption
- Potential system breakdowns from constant strain
Smart Temperature Management Tips:
- Maintain 24°C with a high fan speed during peak heat and humidity conditions
- Adjust 1-2 degrees higher when away
- Use timer or remote management settings for pre-cooling areas, particularly if solar power is available to reduce thermal load in the house before you get home.
- Consider a smart ducted controller for automated temperature control
Sensible temperature settings not only save money but also extends your AC unit’s lifespan. Smarter Air and Electrical can help you optimise your thermostat settings for maximum comfort and efficiency.
