We provide free estimates so you can make informed decisions without any financial pressure upfront.

Our AC Installation Process

A proper AC installation begins long before any equipment arrives at your property. Our process starts with a comprehensive in-home assessment where one of our licensed and insured technicians evaluates your space, existing ductwork, insulation levels, and overall layout. We perform a Manual J load calculation, which is the industry-standard method for determining the precise cooling capacity your home requires. This calculation takes into account factors such as square footage, ceiling height, window orientation, insulation R-values, and even the number of occupants in your household.

Sizing the system correctly is one of the most critical steps in any AC installation. An oversized unit will short-cycle, meaning it turns on and off too frequently, which leads to uneven temperatures, excess humidity, and accelerated wear on components. An undersized unit will run continuously without adequately cooling your space, resulting in higher energy bills and reduced comfort. Our team takes the time to get this step right because it directly impacts every aspect of your system’s performance for its entire lifespan.

Once we have determined the appropriate system size and discussed your preferences regarding brand, efficiency rating, and budget, we schedule the installation at a time that works for you. On installation day, our technicians arrive with all necessary equipment and materials. We handle the complete setup, including mounting the outdoor condenser unit on a proper pad, installing the indoor evaporator coil, connecting refrigerant lines, wiring the thermostat, and testing the entire system for proper airflow and temperature output. We also verify refrigerant charge levels using digital gauges to ensure your system operates at manufacturer specifications.

Choosing the Right System for Your Newmarket Home

The AC market offers a wide range of options, and selecting the right system depends on several factors unique to your property and lifestyle. Central air conditioning remains the most popular choice for homes with existing ductwork. These systems use a split design with an outdoor compressor unit and an indoor air handler or furnace-mounted evaporator coil. Modern central AC units are available with SEER2 ratings ranging from 14 to over 26, with higher ratings translating directly into lower operating costs.

For homes without ductwork, ductless mini-split systems offer an excellent alternative. These systems consist of a compact outdoor unit connected to one or more indoor wall-mounted air handlers via small refrigerant lines. Mini-splits are highly efficient, allow for zone-based temperature control, and require minimal structural modification during installation. They are particularly well-suited for additions, converted garages, or older Newmarket homes where installing traditional ductwork would be impractical or cost-prohibitive.

• Central air conditioning systems are ideal for whole-home cooling with existing ductwork and provide consistent temperatures throughout every room
• Ductless mini-split systems offer flexible zone control without the need for ductwork and are perfect for targeted cooling in specific areas
• Heat pump systems provide both cooling and heating capabilities in a single unit, making them a versatile year-round solution that can reduce overall energy consumption

Energy Efficiency and Long-Term Savings

Energy efficiency is a top priority for most homeowners considering AC installation, and for good reason. According to Natural Resources Canada, space cooling accounts for a significant portion of residential energy use during summer months, and that percentage continues to grow as average summer temperatures increase. Installing a high-efficiency system can reduce your cooling costs by 20 to 40 percent compared to older units rated at SEER 10 or below.

We help our customers understand the long-term value of investing in higher-efficiency equipment. While a unit with a SEER2 rating of 20 carries a higher upfront cost than a base model, the energy savings accumulate year after year. Over the typical 15 to 20 year lifespan of a well-maintained air conditioner, those savings often exceed the initial price difference. Additionally, many high-efficiency models qualify for manufacturer rebates and utility incentive programs that can further offset costs.

Why Proper Installation Matters

Even the most advanced air conditioning equipment will underperform if it is not installed correctly. Industry studies consistently show that improper installation can reduce a system’s efficiency by as much as 30 percent. Common installation errors include incorrect refrigerant charge, poorly sealed duct connections, inadequate airflow across the evaporator coil, and improper electrical connections. These issues not only diminish comfort and increase energy bills but can also void manufacturer warranties and shorten equipment lifespan.

Our team of experienced technicians undergoes continuous training to stay at the forefront of industry advancements, ensuring that we can offer the latest in HVAC technology and best practices. Every installation we complete follows manufacturer guidelines and local building codes.
