Buying a new air conditioner is an important decision that affects your comfort, energy bills, and indoor air quality for years to come. Whether your old AC is failing or you’re upgrading to a more efficient system, choosing the right unit can save you money and prevent future headaches.
At NS Heating & Cooling, we help homeowners choose the right air conditioning systems based on their home size, cooling needs, and long-term comfort goals. Before you make your decision, here are five essential questions you should always ask when purchasing a new air conditioner.
1. What Size Air Conditioner Does My Home Really Need?
Size is one of the most important factors when buying a new AC and many homeowners get this wrong.
If the AC is too small, it will:
- Struggle to cool your home
- Run constantly
- Increase energy bills
- Wear out faster
If the AC is too large, it will:
- Cool too quickly without removing humidity
- Cause moisture problems
- Turn on and off repeatedly
- Lose efficiency
This is why a proper home evaluation and load calculation is essential. A professional will measure:
- Home square footage
- Insulation levels
- Window size and direction
- Room layout
- Heat load
2. What Is the System’s Energy Efficiency (SEER Rating)?
The energy efficiency of your AC affects your monthly electricity costs. Modern air conditioners come with a SEER (Seasonal Energy Efficiency Ratio) rating that tells you how efficiently the unit runs.
Higher SEER = Lower Energy Bills
While a higher SEER system may cost more initially, the long-term savings can be significant. Efficient units also offer:
- Quieter operation
- Better temperature control
- Improved durability
If you want a more energy-efficient home, the right SEER rating can make a big difference.

3. Does the AC Unit Come With a Good Warranty?
A new air conditioner is a long-term investment, so the warranty matters. A strong warranty protects you from unexpected repair costs and ensures long-term reliability.
You should always ask:
- How long is the manufacturer’s warranty?
- Does it cover the compressor?
- Is there a parts warranty?
- Does the installer offer a labor warranty?
- Are extended warranties available?
Purchasing from a reputable HVAC company ensures that your warranty is honored and properly registered.
4. What Maintenance Will the New AC Require?
Every air conditioner needs regular maintenance to run efficiently. Without routine service, even the best system can develop issues such as:
- Higher energy bills
- Reduced cooling efficiency
- Increased humidity
- Shortened lifespan
- Unexpected breakdowns
Professional maintenance includes:
- Cleaning the evaporator and condenser coils
- Checking refrigerant levels
- Testing electrical components
- Replacing air filters
- Ensuring proper airflow
- Inspecting the thermostat
A well-maintained system can reduce cooling expenses significantly and improve overall comfort.
