HVAC stands for heating, ventilation, and air conditioning. These systems allow homeowners to control the temperature of their homes through a thermostat, regardless of what the weather is like outside their homes. As a result, you can create a custom, comfortable living space for you and your family while ensuring the air quality of your interior is clean. All in all, your HVAC system is essential to any home, just like the standard appliances you would find.

There are several factors a homeowner should look for in an HVAC system, including: 

  • The cost 
  • Its lifespan
  • The Seasonal Energy Efficiency Ratio (SEER) rating
  • Maintenance requirements 
  • Its capacity, which is measured in British Thermal Units (BTUs) depending on the size of your home
  • How well the HVAC system will perform in your home depends on the type of comfort you are looking for 
  • The system’s ability to improve your indoor air quality

Sometimes, it can be difficult for homeowners to know when their HVAC system may require maintenance as the signs aren’t always obvious. However, to ensure that your HVAC system runs optimally throughout the years, it’s vital that homeowners book a yearly proactive maintenance appointment. By doing so, you can have a professional technician diagnose potential problems before they become more severe.

Therefore, take a look at some of the signs that indicate something wrong with your HVAC system. If you begin to notice any of these around your home, it may be time to call a team member at Dunn Heating and Air Conditioning for assistance.

  • Strange odors originating from your HVAC system
  • Weird noises such as hissing, rattling, clanking, and grinding coming from your system when it is on
  • Trouble regulating a steady temperature in your house
  • Your system won’t turn on or turns off and on at random times throughout the day
  • The thermostat is inaccurate in comparison to the actual temperature in your home
  • Your HVAC system is leaking water.
  • There is low air pressure coming from your ventilation system.
  • Your experiencing unexplained allergies or cold-like symptoms
  • such as sore throats, itchy eyes, and skin

When it comes to installing a new HVAC system into your home in Ancaster, the cost of the installation will vary on several factors. These factors can include:

  • 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 select to partner with for the installation job
  • The efficiency rating of your HVAC system and its SEER rating requirement for your home

Therefore, to find out more about the cost of installing an HVAC in Ancaster, it’s always best to book a free consultation with a professional HVAC company that can provide you with suggestions and more information on your installation costs.

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.
