5 Common Causes for a Broken Heater and How To Fix It

1. Lack of Maintenance and Regular Cleaning

A dirty HVAC unit can lead to a broken heater quicker than most homeowners realize. Regular HVAC maintenance is about ensuring that all parts of your heater are operating correctly and are properly cleaned on a regular basis.

Over time, dust, debris, and other contaminants accumulate within the heater, slowly eroding its efficiency. Clogged filters, vents, and ducts restrict airflow, causing your heater to work harder which can lead to faster wear and tear and downtime. This can lead to a broken heater due to overworking, overheating, or a general lack of proper connections due to wear and tear.

Solution: Regular maintenance is the key to ensuring optimal heater performance year-round. You want to schedule professional inspections and cleanings at least once a year to remove built-up debris and address any potential issues before they escalate. Make it a habit to replace filters according to the manufacturer’s recommendations to maintain unrestricted airflow and enhance heating efficiency.

To troubleshoot this, check to see if your heater is dirty or dusty. Also check your air filters to see if they are clogged and around your air vents. Scheduling a quick heater inspection can remove the dirt and debris that is clogging the system and can often be fixed quickly and affordably.

2. Thermostat Issues

A malfunctioning thermostat causes more heater repair than people realize. Whether it’s a faulty sensor, inaccurate calibration, or wiring problems, thermostat issues can lead to erratic heating patterns or complete system shutdowns.

Before you go poking around your heater for heater repair, check your thermostat to see if that is why your heater isn’t working properly. This can lead to a quick and easy repair that doesn’t require an inspection from your local HVAC company.

Solution: Start by checking your thermostat settings to ensure they are correctly set for your desired temperature and haven’t been turned off schedule. If the thermostat appears unresponsive or fails to maintain consistent heating, try replacing the batteries or resetting the power on it.

A quick thermostat replacement can also help troubleshoot the issue to see if your old unit has died. Your local HVAC company can check your thermostat as part of their routine HVAC check.

3. Aged Heaters Due to General Wear and Tear

As heaters age, their heating elements deteriorate and develop faults, diminishing their ability to generate heat effectively. In electric heaters, worn-out heating coils or faulty components can lead to reduced warmth output and uneven heating throughout your home.

This lack of regular heat output can cause you to think your heater has stopped working entirely, especially if your primary living areas aren’t getting up to the recommended temperature.

Solution: If your heater exhibits signs of aging or malfunctioning heating elements, it may be time for a thorough inspection by a qualified technician. Look for old or rusted spots, uneven heating throughout the house, consistent on and off powering from the heater, and any odd odors or smells.

Depending on the extent of the damage, repairing or replacing the faulty components can restore your heater’s performance and efficiency. Call an HVAC company near you to replace the faulty part and you’ll be back up and running in no time.

4. Blocked Airflow or Ventilation Issues

Restricted airflow due to blocked vents, ductwork obstructions, or closed registers can hinder the efficiency of your heater. This leads to poor heating and uneven temperature readings throughout your home. It can cause your heater to work harder even though it’s not the cause for lack of proper heat output.

Solution: Take a look at your heating system’s vents, registers, and ductwork to identify any obstructions or blockages. Clear away any debris, furniture, or other objects that may be obstructing airflow and ensure that all vents and registers are open and unobstructed.

Sometimes the answer is as simple as clearing up as many home vents as possible that you didn’t realize were closed or blocked off. 

5. Fuel Supply or Ignition Problems

For heaters powered by gas or oil, issues with the fuel supply or ignition system can prevent the heater from generating heat efficiently. Common culprits include gas valve malfunctions, pilot light failures, or fuel delivery issues, all of which can disrupt the heating process in your home and cause temperatures to drop.

Solution: If you suspect a problem with the fuel supply or ignition system of your heater, it’s important to hire a qualified HVAC technician for diagnosis and repair. They can conduct a thorough assessment of the system, identify the root cause of the issue, and implement the necessary repair or adjustments to restore proper functionality and efficient heating.

When it comes to dealing with gas components or wiring, you don’t want to leave it to chance for mistakes. Most HVAC companies offer emergency HVAC services for heating repair, so you won’t be left waiting for long for a quick fix.
