An HVAC system is quite an investment; hence, it’s worth taking the time to understand its basics before welcoming a new one into your home. Critical factors like choosing the right size, understanding energy efficiency ratings, selecting between different types of systems, and knowing the importance of professional installation should be at the forefront of your thoughts.

We’ll delve into the important factors to consider, the advantages of different types of systems, and the basics of professional installation. So whether you’re ready to replace a decades-old system, or you’re moving into a new home and starting with a blank slate, this guide will help you make an informed decision about what might be one of your home’s most crucial systems.

Navigating the Basics of HVAC System Installation

Choosing the Right Size for Your HVAC System

One of the most critical factors to consider when installing a new HVAC system is selecting the correct size for your home. An improperly sized system can lead to a multitude of issues, including poor temperature regulation, decreased energy efficiency, increased wear and tear on the unit, and a shortened lifespan.

When determining the right size for your new HVAC system, you should consider the square footage of your home, as well as factors like insulation, climate, and the number of windows. A qualified HVAC professional, like those at Fortis Heating, can perform a load calculation to help you choose the correct size system that will meet your home’s heating and cooling needs efficiently.

Understanding Energy Efficiency Ratings

Energy efficiency ratings are critical when selecting a new HVAC system. These ratings indicate how efficiently the system uses energy to heat or cool your home. For air conditioners, you will see a Seasonal Energy Efficiency Ratio (SEER) rating, while furnaces have an Annual Fuel Utilization Efficiency (AFUE) rating.

A higher SEER or AFUE rating signifies a more energy-efficient system, which can translate to substantial energy savings and reduced operating costs over the system’s life. Choosing an HVAC system with a high efficiency rating is not only a responsible decision for the environment but also a smart choice for your wallet in the long run.

Exploring Different Types of HVAC Systems

There are various types of HVAC systems available, each offering unique advantages for specific situations or homeowner preferences. Three common types include:

1. Central Air and Split Systems: A central air system cools your home using a duct system to distribute cold air throughout the house. A split system is the most common central air setup, consisting of an outdoor condenser unit and an indoor evaporator coil connected to your furnace. Split systems are popular choices due to their efficiency and ability to maintain even temperatures.

2. Ductless Mini-Split Systems: These systems consist of an outdoor compressor/condenser unit and one or more indoor air handler units. Ductless mini-splits are ideal for homes without existing ductwork or for additions to your home that don’t have access to the existing duct system. They offer the benefits of individual room temperature control and increased energy efficiency.

3. Heat Pumps: Heat pumps are versatile HVAC systems that can provide both heating and cooling by extracting heat from the air outside and transferring it indoors. They are energy-efficient options for moderate climates, like those in the Durham Region. However, they might require a supplementary heating source during extreme cold snaps.

Discussing your unique needs and preferences with an experienced professional, such as those at Fortis Heating, can help you choose the ideal system for your home.

The Importance of Professional Installation

Professional HVAC system installation is essential to ensure your new unit operates efficiently and safely. An experienced technician will perform crucial steps such as proper refrigerant charging, precise ductwork design, and accurate system sizing, all of which contribute to the system’s performance and your home’s comfort.

Attempting to install an HVAC system yourself or relying on an inexperienced technician can potentially lead to unsatisfactory results, costing you more money and causing potential damage to your system down the road. Trusting a qualified professional like Fortis Heating for your HVAC installation guarantees that your system operates at peak performance, providing maximum comfort and energy savings.


Navigating the basics of HVAC system installation can be challenging, but with a little guidance and the support of experienced professionals like our team at Fortis Heating, you can make an informed decision that benefits your home and family. Understanding the importance of system sizing, energy efficiency ratings, available system types, and professional installation will pave the way for a successful HVAC installation experience.
