HVAC stands for heating, ventilation, and air conditioning systems. These indoor and outdoor systems allow homeowners to control the temperature throughout their home, regardless of what the weather is like outside. HVAC systems are highly complex and include products such as ductwork, heat pumps, air conditioners, thermostats, furnaces, and other systems that can help create comfortable living quarters.

When it comes to purchasing an HVAC system for your home, homeowners can easily feel overwhelmed as there are numerous types of systems available. Therefore, to make your search more efficient, here are some factors you should look for in an HVAC system for your home:

  • Its Seasonal Energy Efficiency Ratio (SEER) rating
  • The system’s capacity, measured in British Thermal Units (BTUs)
  • The maintenance requirements
  • Its average lifespan
  • What sound does it make, if any, when it is operating
  • The price of the system
  • How well it will perform to provide you with the comfort you’re looking for
  • Its ability to improve and maintain the indoor air quality of your home

By taking these factors into consideration, you’ll be able to choose an HVAC system that works for your specific needs so you can enjoy the comforts of your home throughout the year.

Numerous signs can help owners notice when something is wrong with their HVAC system. However, not all of them are common knowledge. Therefore, to ensure you catch potential issues with your HVAC system before it causes further damage, here is what you should look for:

  • Weird odors coming from your HVAC system
  • Odd noises such as clicking, hissing, or rattling
  • Difficulty maintaining a steady temperature throughout your home
  • Your HVAC system won’t turn on at all or will turn on and off at random times
  • The thermostat is inaccurate
  • Your HVAC system is leaking water
  • There is low air pressure coming from your ventilation system
  • You are experiencing allergies or cold-like symptoms

The cost of your HVAC installation in Dundas will be calculated based on several factors, including:

  • The type of HVAC system  
  • The size of your home
  • The type of ductwork you have installed in your home and its current quality 
  • The company you choose to partner with for the installation job
  • The efficiency rating of your HVAC system and its SEER rating requirement for your home.

What Homeowners Say About Us

“After a weekend away we arrived home Sunday night with no AC. I called Dunn first thing Monday morning and had a technician here within the hour! He explained that the unit could either be repaired or replaced and gave us a quote. We decided to replace the unit and that same morning they had a crew here installing it! The installers were friendly, neat, professional and skilled.
Very happy with Dunn and would recommend.
