When Do You Need an HVAC Inspection? 5 Warning Signs

Demand for air conditioning continues to increase in Canada, with the demand tripling in British Columbia alone. But finding an efficient HVAC system is not the end of your worries. You also need to maintain your HVAC system and know when to arrange an HVAC inspection. 

HVAC systems provide the welcome heating and cooling relief households need across Canada and other countries. The global market size continues to increase, last valued at $225 billion to $275 billion due to increasing demand. You can find HVAC systems in different locations, from households to commercial spaces. 

But to maintain your system, you need to know when to schedule HVAC inspections. Read on for the top five HVAC problems that indicate you need to arrange an inspection. 

What Is an HVAC Inspection? 

An HVAC inspection is an evaluation of your system. It helps maintain the efficiency of your heating and cooling system. You want to ensure everything is running efficiently before Canada’s winter and summer seasons hit. You can arrange regular seasonal inspections or book one when you experience HVAC problems.

The inspector will see whether preventive maintenance is needed during an HVAC system inspection, such as replacing the air filter. The inspector will also evaluate the system to make sure it is operating properly, and look for the root causes of any issues you may be experiencing. 

They will bring the equipment and expertise needed to address HVAC problems. The inspection can also identify when you need to replace your system.

The HVAC inspection cost can vary depending on several factors, such as the size of your system, your home, and the HVAC problems. It can range from $150 to $500. 

Warning Signs of HVAC Problems 

HVAC systems can experience a variety of issues. It can be tempting to ignore HVAC problems initially, especially if they seem to be minor, but problems can quickly worsen. If you notice any of these warning signs, it is time to schedule an HVAC inspection. 

1. Unexplained Energy Bill Increases

Some HVAC problems are hard to detect, but your energy bill can give you a clue you need to take action. If you are noticing a steadily increasing energy bill each month or a bill that is much higher than average, it could be due to the HVAC system.

If your HVAC system is switching on and off, it uses more energy. You will also not get the home comfort levels you need.

While there are many reasons why utility bills can increase, if you cannot find another cause, arrange an inspection. 

Regular HVAC inspections also help you reduce utility bills, as they make sure your system will always be running efficiently. Many HVAC problems will cause increased energy bills, including reduced airflow or decreased efficiency due to the age of the system.  

2. Unusual Noises and Smells 

Have you noticed a strange odour around your home? Or is your HVAC system being noisier than usual? Unusual odours are not just an annoyance but can also indicate a problem with your heating and cooling system.

You might hear sounds like rattling, banging, or screeching. There could be loose parts, an issue with the motor, a leak, or another issue that needs fixing.

Smells can also be an indication you need to call a professional. Smells will be unusual, such as a stale or musty smell. This could indicate problems with the condensate drain system. If you smell an electrical or burning smell, shut your system off immediately, as it could be a fire risk.  

3. Change in Airflow 

The airflow is how much air enters and exits your HVAC system. It should be balanced if it is working efficiently, but problems can sometimes change the airflow. Some common air conditioning airflow problems include:

• Buildup of debris on the cooling coils
• Clogged filter 
• Air leaks or disconnected ducts
• Imbalance between ducts sizes due to poor design

Do not ignore this warning sign. Sometimes airflow changes are due to filters needing to be cleaned. However, there could also be a severe blockage due to buildup of dust and dirt on the coils that could cause more damage to your system and higher utility costs if you do not address it. 

Ducts can leak due to various reasons. Animals can damage ducts, creating holes. Joints in ducts can separate, leaving openings where air can escape. Some of these leaks can be hard to find, so you’ll need a professional to evaluate the airflow and see if leaks are a problem.

If your system was poorly designed, there can be airflow issues that will prevent the system from operating with maximum efficiency. If this is found to be the case, it should be corrected so you can get the most out of your investment.

4. Old Age 

How old is your HVAC system? If your system is over eight years old, or you are unsure of its age, ask for an HVAC inspection. Most HVAC units last around ten years or longer if there is regular maintenance.

However, the system is more prone to problems as it ages, so be sure to start scheduling HVAC inspections to make sure you are maintaining it properly to increase its lifespan. 

5. Excess Moisture or Dust

Have you noticed more dust in your living space? You may also be experiencing more allergy symptoms and not know why. More dust in your living space can be due to a dirty HVAC system. 

There are a few reasons why your HVAC system is producing dust. Usually, changing a clogged filter which is not working properly can resolve the problem.

However, other causes such as faulty ductwork or inadequate filtration could also be to blame. It is best to schedule an HVAC inspection, so they can find the root cause of dust before it causes more health issues and dirt in your home.

It is also time to schedule an HVAC inspection if you notice excessive humidity in your home. A system that is not working properly will begin to lose control of humidity levels in your home. There could be several reasons for this, which are causing your system to have reduced efficiency. Your inspection will figure out what the problem is and how to correct it.
