Signs You Need to Replace Your Ductless Air Conditioner
High Energy Costs
Old mini-splits work harder and use more power. A new ductless air conditioner installation with an inverter compressor can cut energy use dramatically.
Frequent Breakdowns
If you're calling for service multiple times a year, a ductless AC replacement will save you money and eliminate stress.
Uneven Room Temperatures
Hot spots or undercooled rooms signal airflow or compressor issues. Multi-zone systems offer precise comfort in every zone.
Noisy Operation
Buzzing or rattling noises often point to compressor or motor failure. New systems operate whisper-quiet.
Old or Outdated System
If your system is 10–15 years old, you're missing out on newer tech like smart features, better air filtration, and higher SEER ratings.
Lack of Wi-Fi or Smart Features
Modern ductless air conditioning systems let you control everything from your phone. Upgrade for better usability and control.

Frequently Asked Questions
How long does it take to install a ductless AC system?
Most single-zone ductless AC installations are completed in one day. Multi-zone or larger setups may take 1–2 days, depending on layout and access.
How much does a ductless air conditioner cost to install?
In Mississauga, ductless AC installation typically costs between $3,500 and $7,000, depending on the number of indoor units, BTU size, and smart features.
What is the disadvantage of ductless AC?
The main downside is the higher upfront cost compared to window units or portable ACs. Also, wall-mounted indoor units may not suit every interior design.
What is the life expectancy of a ductless air conditioner?
With regular maintenance, most ductless air conditioning systems last 15 to 20 years. Inverter models often last longer due to smoother operation.
How many mini splits do I need for a 1500 square foot house?
It depends on your layout, insulation, and number of rooms. Most homes this size need a multi-zone system with 2 to 3 indoor heads.
Do you have to put a mini split in every room?
Not necessarily. You can cool multiple areas with strategically placed indoor units, especially in open-concept layouts. Zoned planning helps minimize the number of heads needed.

A 12,000 BTU mini split typically cools a 450 to 550 square foot room, depending on ceiling height, insulation, and sun exposure.
What is the rule of thumb for ductless mini splits?
A general rule is 20 BTUs per square foot of space. However, we always recommend a professional load calculation for the most accurate sizing.
Will a ductless air conditioner cool a whole house?
Yes, with a multi-zone ductless system, you can cool an entire home. It’s ideal for properties without ductwork or where zoned control is preferred.
Is it worth installing a ductless air conditioner?
Definitely. Ductless systems offer energy savings, quieter operation, easier installation, and zoned control—making them a smart investment in comfort.
