HVAC Troubleshooting: When To DIY vs. Call a Professional

Maintaining a comfortable environment at home means having a fully functioning HVAC system you can rely on to deliver consistent comfort. But what happens when your heater and air conditioner start acting up? Do you roll up your sleeves and fix the problem yourself, or do you call a professional?

In this HVAC troubleshooting guide, the air conditioning and heating experts at Iceberg Home Services explain when it’s best to handle issues yourself and when to seek professional help. This will help you save time and money on your comfort needs.

DIY HVAC Troubleshooting Tips

Before calling a professional, there are a few simple checks and adjustments you can make to potentially resolve minor issues with your HVAC equipment. Some DIY HVAC maintenance and troubleshooting tips include:

Checking the Thermostat

Many common HVAC issues that homeowners run into are actually caused by the thermostat. Ensure that it is set to the correct setting — cooling in the summer and heating in the winter. Also, check the batteries and replace them as needed as dead batteries are a frequent source of HVAC problems. Sometimes simply resetting the thermostat or making sure it is properly programmed can resolve the issue.

Changing the Air Filters

Dirty air filters can significantly hinder the performance of your HVAC system. Filters should be checked every few months and replaced if they are dirty. This easy DIY HVAC repair not only helps in maintaining the efficiency of your equipment but also improves the air quality in your home.

Check Circuit Breakers & Power Supply

Sometimes the problem might be as simple as a tripped circuit breaker or a switched-off power supply. Check your home’s main electrical panel and any secondary circuit panels to ensure there are no tripped breakers. Also, ensure the external unit’s switch hasn’t been accidentally turned off.

Cleaning the Condenser Unit

Leaves, dirt, and other debris can clog the external condenser unit and impede the HVAC system’s efficiency. Cleaning the area around the condenser unit and removing any debris can help improve performance. Ensure the unit is off before you start cleaning.


When To Call an HVAC Technician

Some HVAC issues are complex and require the knowledge and expertise that only a trained professional can provide. Examples of times when it is best to contact an HVAC technician include:

Complex or Persistent Issues

If you’ve tried all the basic troubleshooting steps and the problem persists, or if the system shows complex error codes, it’s time to call a professional. Issues like refrigerant leaks, motor problems, or unusual noises can indicate more serious problems that require professional attention.

Aging Systems

Older systems often need more frequent repairs, which can be complicated and require specific knowledge about outdated technologies and parts. If your system is more than 15 years old and frequently needs repairs, a professional can provide advice on whether it’s more cost-effective to repair or replace it.

HVAC Safety Concerns

HVAC systems involve complex electrical components and, in some cases, natural gas or refrigerant, which can be hazardous. If you suspect a gas leak or encounter electrical malfunctions, it’s important to stop all work and call a professional immediately. Safety should always be the number one priority.

Annual Maintenance

Even if there are no visible issues, having an HVAC technician perform annual maintenance on your system can prevent future problems and ensure efficient operation. This regular checkup can extend the life of your system and save money in the long run.
