What are the Frequent Problems of HVAC Units During Spring

When the weather heats up, and you switch on your air conditioner for the first time this year, you may have several surprise problems. While periodic service visits and tune-ups may prevent many of these issues, you should be on the lookout for any symptoms your HVAC system is failing or approaching the end of its useful life.

What Problems HVAC Units Have During Spring

1. Reversing Valve Problems

The reversing valve is a complex piece of equipment that regulates your home’s temperature by reversing the flow of refrigerants.

If your reversing valve has failed, you may be unable to turn on your heat or air conditioner. Depending on the age of your system, the valve may need to be replaced instead of repaired.

2. Refrigerant Leaks

A refrigerant leak in an HVAC system may not cause you to experience any symptoms. Eventually, it could increase your energy bills or even present an explosion risk. See to it if refrigerant levels are within the appropriate range.

3. Faulty Thermostat

Spring can bring warmer temperatures to your home, changing how your HVAC unit performs. It may be harder to keep a pleasant temperature.

If your thermostat is set correctly, but your HVAC unit cannot reach optimum temperature, you may have an issue with your thermostat.

4. Clogged Air Filters

If you notice that your HVAC is emitting an unpleasant smell or that your system isn’t working as efficiently as it should, it is because the filter is dirty or damaged.

You’ll know when the filter needs to be replaced when the system becomes louder than usual.

5. Fan Motor Failure

If your fan motor cannot extract any air from your home, you will probably notice that your utility bills are higher than they should be. If your HVAC unit is still trying to cool your home, the motor could burn out and need to be changed.

These symptoms could mean that your system is approaching the end of its lifespan.

How To Prepare HVAC Unit Before Spring

1. Replace the Filter

Suppose you do not have a program to check and replace the filter. Ensure that you change it every month during the spring and summer. The filter helps to keep your system running efficiently and clean.

2. Check the Refrigerant Level

You should check the refrigerant levels at least once a year. Remember, if they are too low, your HVAC unit would not be able to pull a suction. If they are too high, there might be a leak, which could mean a possible risk of an explosion.

3. Consider Getting Your Unit Serviced

It is always good to get your HVAC unit serviced before the spring. Make sure that a professional has a look at it. They will check if there are any leaks and if the unit is running efficiently. They will also be able to suggest what you can do to keep your system running well.


As you can see, spring brings several challenges to your home’s HVAC system. If you know what to look for and are proactive about your system’s maintenance, you can keep its lifespan long.

To have a comfortable spring, you should prepare your HVAC system before the season.
