Air Conditioning Units For Condos: What You Need To Know

Air conditioning is essential to comfortable living, especially in hot and humid climates. However, choosing a suitable air conditioning unit for a condo can be challenging, given the unique layout and size of these units.

This article will discuss the different types of air conditioning units available for condos, the factors to consider when selecting one, and other considerations for air conditioning in condos.

Types Of Air Conditioning Units For Condos

Central Air Conditioning Systems

Central air conditioning systems are installed in the entire building and cool the air using a network of ducts. These systems are controlled using a thermostat, and the temperature can be set to the desired level.

Central air conditioning is convenient and efficient, as it can cool the entire condo evenly. However, it requires installation in the whole building, which can be costly and time-consuming.

Window Air Conditioning Units

Window air conditioning units are installed in a single window or through a hole in the wall. These units are relatively inexpensive and easy to install, making them a popular choice for condos. However, they are only capable of cooling a single room and can be noisy and not aesthetically pleasing.

Ductless Mini-Split Systems

Ductless mini-split systems consist of an outdoor unit connected to one or more indoor units through a small hole in the wall. These systems are more expensive than window units, but they can cool multiple rooms and are relatively energy efficient and quiet. However, they require installation in each room, which can be more expensive than installing a single window unit.

Factors To Consider

Size And Layout Of The Condo

The size and layout of the condo will determine the type and capacity of the air conditioning unit required. A larger unit will be needed for a larger condo, and a higher BTU (British Thermal Unit) rating will be needed for a condo with many windows or poor insulation.

Noise Level

If you are sensitive to noise or live in a condo with thin walls, choosing an air conditioning unit that operates quietly is essential. Central air conditioning and ductless mini-split systems are the quietest options.

Energy Efficiency

Air conditioning units can be a significant source of energy consumption, so it is essential to consider the energy efficiency of the unit you choose. Units with a high energy efficiency ratio (EER) will use less energy to cool the same amount of space.

Cost

The cost of the air conditioning unit is an important consideration, as it can vary significantly depending on the type and size of the unit. Central air conditioning systems are the most expensive, followed by ductless mini-split systems and window units.

Maintenance And Repair Requirements

Air conditioning units require regular maintenance and may need repairs from time to time. It is essential to consider the maintenance and repair requirements of the unit you choose and the availability of technicians to perform these services.

Pros And Cons Of Different Types Of Air Conditioning Units

Central Air Conditioning

Pros:

Even cooling can be controlled remotely, relatively quiet

Cons:

Requires installation in the entire building, it can be expensive to install and maintain

Window air conditioning units

Pros:

Relatively inexpensive and easy to install.

Cons:

Limited to cooling a single room, it can be noisy and may need to be more aesthetically pleasing.

Ductless Mini-Split Systems

Pros:

It can cool multiple rooms, is relatively energy efficient, and is relatively quiet.

Cons:

More expensive than window units requires installation in each room.

Other Considerations For Air Conditioning In Condos

Hoa Rules And Regulations

It is essential to check with your homeowners association (HOA) to see if there are any rules or regulations regarding the installation and use of air conditioning units in your condo. Some HOAs may have restrictions on the type or location of the unit or may require approval before installation.

Energy Usage And Cost

As mentioned earlier, air conditioning units can be a significant source of energy consumption. It is essential to consider the energy usage and cost of the unit you choose and any energy-saving features it may have.

Environmental Impact

The energy usage and emissions of air conditioning units can impact the environment. Consider choosing an energy-efficient unit with a low carbon footprint to minimize your environmental impact.

Conclusion

Air conditioning is essential to living in condos, and choosing a suitable unit is crucial for ensuring comfort and energy efficiency. Three main types of air conditioning units are available for condos: central air conditioning, window units, and ductless mini-split systems.

Each type has its pros and cons, and it is essential to consider the size and layout of the condo, noise level, energy efficiency, cost, and maintenance and repair requirements when selecting a unit.

Other considerations for air conditioning in condos include HOA rules and regulations, energy usage and cost, and environmental impact. By taking the time to research and consider these factors, you can find the perfect air conditioning unit for your condo.

The Best Air Conditioning Units for Homes in London, Ontario

By kevin Wu • May 20, 2025

As climate patterns shift and summers grow hotter across Canada, homeowners are increasingly turning to air conditioning as a necessary part of daily comfort. But with that comfort comes a cost—both financially and environmentally. If you're tired of soaring electricity bills or want to reduce your household's energy use, investing in the best energy-efficient air conditioners in Canada is a smart move. This guide is here to help you understand what makes an air conditioner energy-efficient, what types are most suitable for Canadian homes, and which models top the charts in 2025. We'll also look at common misconceptions and practical insights to help you make an informed decision without relying on guesswork—or risky DIY installations. Key Takeaways Energy-efficient AC units can significantly lower electricity costs and reduce your carbon footprint. In Canada, features like Energy Star certification and high SEER ratings matter most. Choosing the right AC isn’t just about the unit—it's also about correct installation and expert servicing. Carver Sheet Metal in London, Ontario offers expert advice and trusted installation services for the best air conditioning units Canada has to offer. What Makes an Air Conditioner Energy-Efficient? Understanding SEER and Energy Star Ratings When evaluating energy-efficient air conditioner , the Seasonal Energy Efficiency Ratio (SEER) is a crucial metric. This number indicates how much cooling a system delivers per unit of energy consumed. In Canada, a SEER rating of 14 or higher is generally considered efficient. Many of the best air conditioning units Canada homeowners trust have SEER ratings well above 18. Energy Star certification is another key indicator. These models meet government-backed standards for efficiency without sacrificing performance. According to Natural Resources Canada, switching to an Energy Star-certified AC can reduce cooling costs by up to 30% annually. Central vs. Ductless vs. Portable Units There’s no one-size-fits-all solution. Central air systems are ideal for larger homes, especially those with existing ductwork. Ductless mini-splits offer more flexibility and room-by-room control, making them perfect for renovations or homes without ducts. Portable units, while convenient, often lag in energy efficiency. If you’re in a city like London, Ontario, with its mix of older and newer homes, it’s critical to match the type of unit to your home’s structure and insulation level. That’s why professional consultation is key—something Carver Sheet Metal excels at. Why Energy Efficiency Matters More in Canada Our Unique Climate Demands Better Tech Canadian summers can swing from mild to sweltering, depending on the region. While a basic unit might suffice for coastal areas, inland cities like London, Ontario often face sharp temperature spikes. An energy-efficient air conditioner adapts better to these fluctuations while keeping consumption low. Furthermore, Canada's electricity prices vary by province, with Ontario typically ranking among the higher cost zones. Investing in a high-efficiency AC helps mitigate those long-term costs. Environmental Impact The environmental benefit of using an energy-efficient system cannot be overstated. Less power usage means fewer emissions. With Canada targeting net-zero emissions by 2050, every household can contribute by upgrading their cooling systems. Features to Look For in 2025 Smart Thermostat Compatibility More units now pair with smart thermostats, allowing better temperature control and scheduling. This minimizes energy waste and improves comfort. Variable-Speed Compressors Unlike traditional systems that switch on and off, variable-speed compressors adjust gradually. This reduces energy spikes and prolongs the unit’s lifespan. Quiet Operation & Compact Design Noise may not be the first thing that comes to mind, but it affects your living space significantly. Modern energy-efficient models are quieter and better suited for family or multi-use spaces. Top 5 Energy-Efficient Air Conditioners in Canada (2025) While we’re not naming specific brands to stay focused on your needs rather than promotion, here's what the top-rated units on the market share: SEER Ratings of 18–26 These are among the highest on the market and ideal for long-term savings. Energy Star Certified Every top pick meets or exceeds government standards. Wi-Fi Connectivity Control via smartphone apps for better energy management. Multi-Stage Cooling Offers customizable comfort while using less electricity. Trusted Warranty Longer coverage usually signals quality parts and engineering. Each of these features contributes to lower operational costs and a reduced carbon footprint—goals every homeowner in Canada should prioritize. Why DIY Isn’t the Answer for Installation Energy-efficient systems are only as good as their installation. A poorly installed AC unit, no matter how advanced, can leak air, short cycle, or draw too much power—completely offsetting any potential savings. In fact, government and utility providers recommend professional installation not just for efficiency but also for safety and warranty compliance.

These certifications mean the product meets national standards for energy performance. Q: Is it worth the higher cost of an energy-efficient air conditioner? A: Yes. While the upfront price may be higher, the long-term savings on electricity bills and reduced maintenance usually pay off within a few years. Q: How much can I save annually with an efficient air conditioner? A: Estimates vary, but Canadian homeowners often save 20–30% on cooling costs when upgrading from older systems. Q: Do energy-efficient ACs work well in older homes? A: Absolutely. Many ductless models are designed for retrofit applications and can be installed without major renovations. Q: Should I size the unit myself? A: No. Proper sizing requires a load calculation that factors in your home’s size, insulation, windows, and more. Always consult a professional.
