Purchasing a new air conditioner is a significant investment, and making the wrong choice can lead to inefficiencies, high energy costs, and frequent maintenance issues.
Whether you’re debating between central AC and split AC, choosing the right AC efficiency rating, or considering inverter ac vs non inverter, avoiding common mistakes can help you find the best home cooling solutions for your needs.
This guide will walk you through the top mistakes to avoid when you buy air conditioner and help you make an informed decision.
1. Choosing the Wrong Type of Air Conditioner
One of the biggest mistakes homeowners make is selecting the wrong type of AC for their space. Understanding the differences between ducted vs ductless AC and central AC vs split AC is crucial.
- Split AC systems are best for cooling individual rooms and are more energy-efficient.
- Central AC provides whole-home cooling but requires existing ductwork.
- Ductless systems (multi-split ACs) allow flexible room-by-room cooling without ducts.
- Ducted AC is ideal for large homes with multiple rooms but can be expensive to install.
Before purchasing, evaluate your home size, cooling needs, and installation feasibility.
2. Ignoring Efficiency Rating of AC
Many buyers focus only on price and cooling capacity while ignoring the efficiency rating. A low-efficiency AC may have a lower upfront cost but will result in higher electricity bills.
- Look for models with a high star rating and Seasonal Energy Efficiency Ratio (SEER) above 16 for better long-term savings.
- Inverter AC vs non-inverter: Inverter ACs adjust their speed based on cooling demand, saving up to 30-50% on energy compared to non-inverter models.
Choosing an energy-efficient model ensures cost-effective cooling over the years.
3. Buying the Wrong Size Air Conditioner
Size matters when you buy air conditioner. An AC that’s too small will struggle to cool your home, while an oversized unit will cycle on and off too frequently, wasting energy.
- Small spaces (up to 20m²): 2.5kW to 3.5kW AC
- Medium spaces (20m² - 40m²): 3.5kW to 5kW AC
- Large spaces (40m² - 60m²): 5kW to 7kW AC
Always consult with an HVAC expert before finalizing your purchase.
4. Overlooking Installation Costs and Requirements
Many buyers focus solely on the AC unit’s price without considering installation costs. Improper installation can lead to reduced efficiency, frequent breakdowns, and higher energy bills.
- Ducted AC systems require professional installation and may involve additional ductwork expenses.
- Split ACs need proper wall placement and clearance for optimal performance.
- Ensure the AC is installed with correct insulation, wiring, and placement for maximum efficiency.
Skipping proper installation can cost you more in the long run.
5. Ignoring Smart and Advanced Features
Modern ACs come with smart features that enhance efficiency and convenience, but many buyers overlook them.
- Wi-Fi-enabled ACs allow remote control via smartphone apps.
- Smart thermostats help optimize temperature settings for energy savings.
- Auto-clean functions prevent dust buildup and improve air quality.
Investing in an AC with smart technology ensures better long-term performance.
6. Not Checking Warranty and After-Sales Service
ACs require maintenance, and a poor warranty can lead to costly repairs.
- Always check warranty periods for parts and labour.
- Ensure after-sales service availability in your area before purchasing.
- Choose a brand with a strong reputation for customer support.
A good warranty ensures peace of mind for your investment.
7. Buying at the Wrong Time
AC prices fluctuate throughout the year, and buying during peak seasons can be expensive.
- The best time to buy air conditioner is during off-seasons like autumn or winter when demand is low.
- Look for seasonal sales and discounts from retailers.
Timing your purchase right can help you save significantly.
8. Neglecting Air Quality and Filtration Features
Many people buy air conditioner without considering its impact on indoor air quality. Poor air filtration can lead to respiratory issues and allergies.
- Choose ACs with HEPA or antibacterial filters to reduce pollutants.
- Consider dehumidifier functions in humid areas.
- Ensure regular filter cleaning to maintain air quality.
Prioritizing air filtration helps create a healthier living environment.
9. Not Researching Rebates and Incentives
In Australia, government rebates are available for energy-efficient home cooling systems.
- Energy Savings Scheme (NSW) and VEEC (VIC) offer rebates for high-efficiency air conditioners.
- Research local rebates before purchasing to maximize savings.
Checking for incentives helps reduce the upfront cost of your AC.
Conclusion
Avoiding these common mistakes when buying an AC can help you choose the best home cooling solutions while saving money and energy in the long run.
Whether deciding between central AC vs split AC, checking the AC efficiency rating, or choosing between inverter AC vs non-inverter, making an informed decision ensures long-lasting comfort and efficiency.
FAQs
The best time to buy an AC is during off-peak seasons (autumn or winter) when demand is low, and discounts are available.
Central AC is best for large homes needing whole-house cooling, while split AC is more energy-efficient for individual rooms.
Inverter ACs adjust cooling output based on temperature needs, reducing energy use, while non-inverter ACs run at a fixed speed and consume more power.
Look for a high SEER (Seasonal Energy Efficiency Ratio) rating and energy star labels. ACs with higher star ratings are more energy efficient.
Consider size, efficiency rating, installation cost, smart features, air filtration, and warranty before making a purchase.
