24/7 peace of mind for Cambridge homeowners.

Situated on the scenic Grand River, living in Cambridge offers so many unique experiences, from strolling along the many trails and parks along the Grand and Speed Rivers, to exploring the trendy Gaslight District or quaint shops in Hespeler Village.

You want the experience in your home to be just as enjoyable, but if it’s too cold in winter or too hot in summer, it’s hard to enjoy much of anything.

That’s why your home comfort is our priority 24/7/365, and Dunn Heating has the solutions.


Often, we as homeowners won’t pay attention to our home appliances and systems until something is wrong. Therefore, it can be difficult to indicate whether our HVAC unit is, in fact, working as optimally as it should be in your home, regardless of what time of year it is –especially if you aren’t sure if there are any signs you should be looking out for in the first place. 

However, there are ways to know if your HVAC system is working correctly. Here is a closer look at how you can do so in your own home: 

  • Your HVAC filter will be clean
  • Your monthly energy bill will remain low and consistent throughout the year
  • No odd odors are coming from your unit or inside your home
  • Your HVAC unit is quiet, even when it is functioning 
  • You can control the temperature of your home easily 
  • The temperature on your thermostat is consistent with how you feel in your home
  • Your home is not dusty nor stuffy 
  • You are not experiencing any allergy or cold-like symptoms such as itchy skin, eyes, sore throats, or other respiratory symptoms 
  • You clean or replace your HVAC filter every 1 to 3 months to ensure that it is not clogged with any dust, dirt, hair, or other debris
  • You stay on top of your yearly HVAC maintenance 

Ensure your HVAC system is working correctly with the professional help of Dunn Heating and Air Conditioning! Remember, maintenance is key to preventing problems from occurring, saving you money in the long run!

Most of the time, your HVAC system doesn’t receive the level of care it needs to function optimally. However, committing to a proactive HVAC maintenance schedule is one of the best ways to extend the longevity of your unit, save money on your monthly energy bill, and avoid unexpected, costly repairs that could have otherwise been prevented. Therefore, we suggest getting your HVAC system maintenance at least once a year. 

Preferably, homeowners will want to do this in the early fall to ensure their heating unit is working optimally without any problems. At the same time, if you do have central air conditioning installed in your home, homeowners may also want to service their HVAC unit in the spring. Hence, they can diagnose any potential problems before the weather begins to heat up. On the other hand, if you live in a home with pets and a larger family, you may wish to service your HVAC system more often as the level of airborne debris such as dust, dirt, hair, and other contaminants can get into your system at a higher rate which may cause problems

HVAC units come in all shapes and sizes. With that being said, average HVAC units tend to last anywhere from 10 to 20 years before needing to be replaced entirely. However, like any home appliance, your HVAC system is likely to need repairs and maintenance throughout its lifetime to operate optimally for you and your home. Therefore, we suggest that homeowners stay up to date with an HVAC maintenance plan. 

Not only will frequent maintenance help diagnose potential problems early, but it will also help homeowners extend the longevity of their unit and ensure that their energy efficiency is optimized to ensure they are not paying through the roof on their monthly energy bill. Again, staying on top of yearly maintenance for your HVAC in Cambridge can help prevent unexpected repairs that can be costly. However, it doesn’t necessarily mean that you won’t experience any issues with your HVAC system when you have had it. Therefore, take note of the following signs that could indicate there is something potentially wrong with your home’s HVAC system:

  • There is an odd smell coming from your HVAC system as it functions, such as a burning smell of mold and mildew.
  • You hear odd noises, including rattling, hissing, and clicking from your HVAC system or throughout your ductwork. 
  • Significant increases in your monthly energy bill 
  • You are having trouble regulating a consistent temperature in your home. 
  • Your thermostat is inaccurate.
  • There is water leaking and pooling out of your HVAC system when it is turned on. 
  • You cannot turn your HVAC system on.
  • There is low air pressure coming from your vents, leading to patches of heated and cooled air in each room. 
  • You and your family are experiencing unexplained allergies and cold-like systems that can make living in your home uncomfortable. 
  • Your home is exceptionally dusty regardless of how often you clean it. 

At the same time, if you have never changed your HVAC system when you have lived in your home, then chances are it is not working as optimally as it should and will likely need to be replaced. The best way to know is to book a free consultation with Dunn Heating and Air Conditioning for a thorough and accurate inspection.

For over 55 years, the professional technician team at Dunn Heating and Cooling has proudly helped homeowners install their HVAC in Cambridge. We’ve recognized that not every home or homeowner is the same during this time. In other words, HVAC installation is not a one-size-fits-all solution. 

For this reason, to determine the cost of installing a new HVAC unit in your home, a licensed and certified technician would need to first come to your property and conduct a thorough inspection of various factors before they can provide suggestions on what type and size HVAC system will function optimally based on your unique needs and requirements. Until then, we can provide you with a list of some of the factors that will ultimately affect the installation cost for your unit. Here is a closer look at these factors: 

  • The SEER rating, also known as the Seasonal Energy Efficiency Ratio, of the unit required to efficiently control your home’s temperature throughout the year while saving you as much money on your energy bill as possible. 
  • The type of HVAC system you want to install if they are different compared to the HVAC system you presently have installed in your home. 

Another critical factor determining the cost of your HVAC in Cambridge is the size and power of the system you choose. This is determined by how many British Thermal Units (BTUs) are required to heat and cool your home efficiently. Therefore, some factors that determine how many energy units you need will include: 

  • The total square footage of your home 
  • The age of your home
  • The height of your ceilings 
  • The style, type, and quality of ductwork you currently have installed in your home. 
  • The layout of the rooms and floors in your home 
  • The quality of your home’s insulation 

Choosing and installing an HVAC unit in your home isn’t easy. However, with the professional help and guidance of Dunn Heating and Air Conditioning, homeowners can have a stress-free experience that is efficient, friendly, and reliable.

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.
