Expert Guide: Diagnosing and Fixing Heating System Problems in Bakersfield, CA

December 27, 2023

With the cold months approaching in Bakersfield, CA, many families are turning on their heating systems for the first time this season. 

However, many are noticing a faulty system. That’s nothing short of frustrating. Heating systems are complex systems, and there are many components. From the thermostat to the ductwork, each component is essential. If one piece is not working, then the whole system malfunctions. That’s why regular maintenance is necessary. 

We understand that it can be overwhelming if it breaks down or faults, but Grogan Mechanical is here to help!  

There are many reasons why your heating system may malfunction. Sometimes it is an easy fix, but sometimes it is time to call a professional. Grogan Mechanical is ready to help you diagnose your issue at hand and figure out the next steps.

Below are six reasons why your heating system may not be working properly: 


  • Low Refrigerant 
  • Mechanical Wear-And-Tear 
  • Lack Of Maintenance
  • Thermostat Issues 
  • Clogged Air Filter 
  • Cracked Heat Exchanger 


Low Refrigerant 

Some heating systems, such as heat pumps, use refrigerants to cool your home. This is done by transferring energy from one place to another. 

When there is low refrigerant, your heating system will not work correctly. It will seem like you can’t keep your home cool enough. It is usually caused by leaks in your heating system.

Six signs that you may be low on refrigerant include: 


  • Poor Cooling  
  • Short-Cycling
  • High Electric Bills
  • Ice Buildup On Refrigerant Lines 
  • Water Leaks
  • Hissing or Bubbling Noises 

Low refrigerant can cause long-term effects on your overall heating system, such as broken compressors and frozen evaporator coils. 

Remember, refrigerant is a toxic chemical and should only be handled by professionals. If you notice any of these signs at your home in Bakersfield, CA, give us a call and we will help you out! 



Like anything else you own, your heating system can wear and tear. When one component of your heating system is heavily worn, this can cause a faulty heating system overall. It may lead to overheating, poor heating and cooling, and airflow complications. 

The most common components in heating systems that experience wear and tear are belts, bearings, compressors, and motors. It is important to keep up with proper maintenance of your heating system to avoid such issues.   


Lack Of Maintenance 

To avoid unexpected problems and breakdowns, it is important to regularly maintain your heating system. Heating maintenance is essential to making sure your heating system is operating safely and efficiently all year round. 

At Grogan Mechanical, we offer both gas furnace and heat pump maintenance. We have a great team of technicians ready to help. 


Blower Motor Issues 

A faulty blower motor could be the reason why your heating system is not working properly.  The blower motor is responsible for blowing the heated air throughout the home.  If it malfunctions, it will cause uneven cooling.  


Thermostat Issues 

The thermostat is at the core of your heating system and is responsible for keeping your home at your desired temperature. When it malfunctions, it may send signals to the heating system to set the temperature too high or too low. The most common reason for a faulty thermostat is dead batteries, which is a quick fix. 

But, sometimes, it is more than that.  It could be an issue within the electrical hardware, such as poor wiring or a blown fuse. Luckily, a Grogan Mechanical technician can easily handle these issues and get your thermostat running smoothly again.  


Clogged Air Filter 

An air filter is essential to keeping the air throughout your home clean. The air filter is responsible for collecting everything from dirt to debris. Sometimes you will find that the filter gets clogged and will cause your heating system to fail. 

Some signs of a clogged air filter include excessive dust or high energy bills. At Grogan Mechanical, we recommend that you change your filter every 90 days, sometimes sooner, to avoid a clogged air filter.  


Cracked Heat Exchanger 

The heat exchanger is used in heating systems to transfer thermal energy from one medium to another. When they are overheated, they can crack. They can also crack when there is low airflow due to heat stress. 

Even a simple crack can cause your entire heating system to malfunction.  

These are several signs that you might be experiencing if you have a cracked heat exchanger: 

  • Strange Smells.  If your heat exchange is broken, it will create an unpleasant odor. 
  • Change in Flame Color.  If your gas furnace produces a yellow flame, rather than a blue flame, this may be a sign you have a damaged heat exchanger. 
  • Carbon Monoxide Leak.  A cracked heat exchanger could cause your carbon monoxide detector to go off. 
  • Soot Build Up. Take notice if there is soot buildup around your furnace. 

When it comes to a damaged heat exchanger, the best option is to either replace the furnace or the heat exchanger.  If you think you may have a cracked heat exchanger, give Grogan Mechanical a call. 


How To Prevent Breakdown 

There is nothing worse than an unexpected breakdown of your heating system. 

Below are several ways to prevent your heating system from not working: 


  • Regular Heating Maintenance. We recommend getting your heating system inspected at least once a year to ensure it is working properly and to avoid potential issues.  At Grogan Mechanical, we offer gas furnace maintenance and heat pump maintenance to homeowners in Bakersfield, CA. 
  • Change Air Filters. It takes less than five minutes to replace your filters. We recommend changing them every 90 days to avoid a clogged air filter.
  • Keep Air Vents Open. Avoid putting furniture, curtains, or other items in front of air vents for optimal airflow. 
  • Regularly Clean Unit. A clean HVAC unit is essential for consistent performance and reduced repair costs.
