Clearing the Air: Tips for Choosing The Right Type of Air Conditioner System For Your Home
1. Determine the Right Size for Your Space
Choosing the correct size for your air conditioning unit is crucial. A unit that’s too small will struggle to keep up, leaving you in a sweaty mess, while one that’s too large can lead to unnecessary energy consumption and inconsistent cooling. To find the perfect balance, consider your space’s square footage, ceiling height, insulation levels, and window placement.
A quick rule of thumb? Match the horsepower (HP) of your new air conditioner unit to your room size:
- 0.5 HP – Up to 150 sq. ft. (small bedrooms, offices)
- 1.0 HP – 150-300 sq. ft. (standard bedrooms, small living rooms)
- 1.5 HP – 300-500 sq. ft. (larger bedrooms, medium-sized living rooms)
- 2.0 HP – 500-750 sq. ft. (large living rooms, open-concept spaces)
- 2.5 HP+ – 750+ sq. ft. (spaces with high ceilings and poor insulation)
Choosing an AC unit with the right horsepower ensures efficient cooling without overworking the system. If you’re unsure, an experienced air conditioning company, like Crystal Waters, can perform a load calculation to determine the perfect fit for your home.
2. Explore Different Types of Air Conditioning Systems
There are various air conditioning systems available, each catering to different needs and home layouts:
- Central Air Conditioning – Ideal for whole-home cooling, a central AC uses ductwork to distribute cool air evenly.
- Ductless Air Conditioner – A ductless system is a great choice for homes without ducts, offering zoned cooling with wall-mounted units.
- Portable Air Conditioner & Window Units – Cost-effective solutions for smaller spaces, though they may not be as efficient as built-in systems.
Crystal Waters provides top-quality air conditioning solutions in Calgary for various types—count on us to service all makes and models to ensure long-term efficiency and comfort.

3. Check Energy Efficiency Ratings
A high-efficiency air conditioning unit can significantly reduce your energy costs. Look for systems with a high SEER (Seasonal Energy Efficiency Ratio) rating and ENERGY STAR certification. These units consume less electricity while keeping your home cool, making them an environmentally friendly and cost-effective choice.
4. Consider Smart Features and Controls
Modern air conditioning systems come with advanced features that enhance convenience and efficiency. Some key features to look for include:
- Smart Thermostats – Allow you to control temperature remotely via smartphone apps.
- Programmable Settings – Let you set cooling schedules to save energy.
- Air Purification Filters – Improve indoor air quality by reducing allergens and dust.
- Quiet Operation Modes – Perfect for bedrooms or home offices where noise is a concern.
Crystal Waters offers expert recommendations on air conditioning systems with these advanced features to maximize comfort.
5. Factor in Installation Requirements
Air conditioning installation is not a one-size-fits-all process. Factors such as existing ductwork, available space, and electrical compatibility can influence installation costs and complexity. Crystal Waters’ HVAC specialists handle installations efficiently, ensuring your system is set up for optimal performance and longevity. If you’re looking for new construction plumbing & HVAC, we also provide rough-in installations for a seamless, high-performance setup.
6. Plan for Future Maintenance and Repairs
Regular air conditioning maintenance keeps your system running efficiently and prolongs its lifespan. Some key maintenance tasks include:
- Cleaning or replacing air filters regularly
- Checking refrigerant levels
- Inspecting and cleaning coils
- Ensuring proper airflow through vents
When it comes to comprehensive air conditioning service—including preventative maintenance and air conditioning repair—Crystal Waters is here to ensure your unit stays in peak condition year-round.
7. Don’t Overlook Rough-Ins and Pre-Installation Considerations
If you’re building a new home or undergoing renovations, planning ahead for your air conditioning system is vital. Crystal Waters specializes in new construction HVAC solutions, offering expert rough-in services, custom system design, and efficient installations at the foundational stages of construction. Partnering with a trusted provider early in your project can help avoid costly changes later.
8. Understand Warranty and Service Agreements
Before purchasing an air conditioning unit, review the manufacturer’s warranty and any additional service agreements offered by your air conditioning company. A good warranty can protect against unexpected repairs and ensure peace of mind.
Many companies also provide maintenance plans that cover annual inspections and priority service in case of breakdowns.
9. Consider Local Climate and Seasonal Needs
For homeowners in Calgary, it’s important to choose a system that can handle both hot summers and chilly winters. Some air conditioners come with heat pump functionality, providing cooling in summer and heating in winter. With our heating and air conditioning experts, you’ll find a unit that’s perfectly suited to Calgary’s fluctuating temperatures in no time.
10. Work with a Trusted Air Conditioning Service Provider
Keep in mind that choosing the right air conditioning service company is just as important as selecting the unit itself. Look for a provider with:
- A strong reputation and customer reviews
- Certified technicians
- Comprehensive air conditioning service and repair options
- Transparent pricing and warranties
