In 2019, the market size for HVAC systems was $240.8 billion globally. And in turn, that means countless homes have HVAC systems installed. 

And with so many people placing these systems in their homes, they are sure to run into some sort of HVAC problems at one time or another. 

However, if they’re aware of the most common problems that need air condition service and repair, they’ll be more prepared from the start. 

So if you’re interested in the most common problems to expect from your HVAC unit, keep reading! 

1. Water Leaks

Water leaks are one of the most common reasons an HVAC company needs to be called for repairs. If not treated the proper way, it can cause other serious problems to your home or unit. 

These water leaks usually come from the drain pan or drain line. This happens when they become clogged and result in the water finding another place to escape. Usually, they become clogged from dirt, mold, or mildew due to the system’s moisture. 

So checking these lines often is a great way to keep up with maintenance and prevent harmful clogs. If a clog does occur, your technician will vacuum the lines to clear them. 

2. Tripping Breakers

When your HVAC system stops working completely, a good first thing to check is your breaker. If you can see that it tripped its breaker, start looking for mechanical issues. 

This usually means that your unit was working in overdrive to try to maintain the temperature. Usually meaning, that the blower was working harder than it was supposed to. 

Most likely this is due to dirty air filters. So clean the filters and then reset the breaker and see how your unit reacts. If it still trips the breaker, look for other airflow blockages that may hinder its performance. 

If the problem still occurs, you may need to contact your HVAC repairmen. 

3. Refrigerant Leaks

In your HVAC system, you have a chemical that cools the air, otherwise known as refrigerant. This is an essential part of your cooling system that absorbs the heat and transfers it to cool air.  

So when you notice that your home is not cooling properly or fluctuates between temperatures often, you most likely have a refrigerant leak. 

Most people think adding more to the system will fix the problem. However, it will leak out again soon. Therefore, it’s imperative to find the leak and fix it before refilling. 

Always make sure your repairmen find the leak first. Because refrigerant is expensive and can be a waste when it is only topped off. 

4. Faulty Thermostat

Faulty thermostats are a cause of many problems. If you ever notice your heating and cooling system is running weirdly, check your thermostat. And remember, always replace old and outdated thermostats to avoid any future problems. 

A good sign that your thermostat is not working properly is if your system keeps running after the desired temperature is reached. Be sure to monitor this often. 

But, before you replace it, be sure to consult your HVAC company to make sure that is the problem. If it is, they will then recommend a good replacement that will work with your system. 

5. Furnace Ignition

Other than cooling, your HVAC system also contains a furnace. And of course, heating problems can arise during the winter. One of the most common problems deals with the ignition. 

Meaning that your furnace has a hard time starting overall or staying on. Checking your ignitor or burners for dirt is a great place to start. 

Once you find the source of the problem, don’t forget to perform regular maintenance and cleaning to avoid these problems again. 

But, be sure to consult your HVAC experts first since you’ll be dealing with natural gas or electricity. 

6. Dirty Coils 

Your evaporator coils are an essential part of your HVAC system. When they can’t transfer heat efficiently, you’ll notice problems within your HVAC unit. Usually, you’ll notice poor overall performance or higher bills. 

A huge reason these coils often have problems is from being dirty. Once buildup starts forming, they don’t work as well. Plus, depending on what the buildup is made from, they can affect indoor air quality (IAQ) as well. 

For example, if your coils are contaminated with mold and mildew, it can cause breathing problems for those inside the home. However, regular maintenance and cleaning can prevent bigger or harmful problems in the long run. 

7. Running Fan 

If you notice your fan is always running, this can indicate a problem. Your HVAC system will shut off when the desired temperature is reached. Unless you have the fan switched on. 

However, if it’s on “auto” and never shuts off, this means a malfunction has taken place. Most likely, a switch or relay has stopped working and needs to be replaced. Or it could mean your fan is close to reaching the end of its lifespan and needs replacement. 

Your HVAC company can do these repairs for you fairly easily with the necessary equipment.
