Heater Repair in Frederick, MD

Your heater is vital to keeping you warm during cold weather, but if it doesn’t turn off, the problem can be incredibly frustrating and inconvenient. Typically, your heater should have normal cycles of turning on and turning off. If your furnace keeps on running continuously, it will end up consuming a lot of energy and lead to exorbitantly high-utility bills. Additionally, the temperature in your home may rise too high, threatening your comfort and health.

Issues Affecting Your Heater

Various reasons can cause your furnace to run continuously. Here are some issues that can affect your heater and lower its efficiency:

  • Clogged air filter
  • Leaking ductwork
  • Damaged blower motor
  • Wrong thermostat setting
  • Damaged thermostat

Proper heater maintenance can help to prevent these problems and avoid costly repairs. You can schedule an annual tune-up to increase the efficiency of your furnace and prolong its service lifespan. During the tune-up, the HVAC technician will inspect your system to check for any lurking issues. The technician will also adjust your thermostat correctly. This helps avoid overworking the furnace and unnecessarily increasing your energy bills.

You can also rely on a professional HVAC technician to diagnose the cause of your heater running incessantly. Let’s more closely examine the issues outlined above.

Air Filters

Air filters prevent air pollutants from entering your indoor air by trapping debris, dirt and pollen. These contaminants can accumulate over time, clogging your filters. Clogged air filters can decrease airflow in your home, causing your heater to run continually.

It’s important to change your air filters regularly, preferably once every three months. Various factors affect how long you should wait before changing your filters. House pets like cats and dogs shed fur that is trapped by the air filters. If you have pets, you may have to replace your filters more frequently. Smoking also increases the level of contaminants in your indoor air, which could clog your filters.

Keeping your doors and windows open will introduce pollutants from the outdoors and increase the amount of dust in your indoor air. This means that your filters are more likely to get clogged faster than usual.

The type of filter you are using in your house will also determine how frequently you should replace them. Washable filters do not need to be replaced often, but they do need to be cleaned to remove pollutants. Filters with high MERV values capture more particles and require more frequent replacement.


Setting the temperature too high means your heater will work harder to try to achieve that setting and consequently run longer. If your fan switch is in the “ON” mode, the furnace’s fan won’t stop running.

A faulty thermostat can affect your heater and cause it to run continuously. Your thermostat can also have faulty wiring. This can prevent the thermostat from sending or receiving signals to the heater. Electrical issues with your thermostat require a professional HVAC technician to fix them.

Damaged Blower Motor

The blower is responsible for blowing heated or cooled air throughout your home. It is composed of various parts that need to be serviced from time to time. A fault in your blower motor can cause it to keep running, or it could also cause the motor to stop working altogether. If your blower has issues, you need a licensed HVAC technician to check it out and isolate the problem. Dealing with electricity can be dangerous, and it’s better to leave a task like this to qualified technicians.

Ductwork Leaks

Air ducts circulate conditioned air throughout your home. However, they can have issues that affect their efficiency and undermine your air supply. If the ducts have leaks, conditioned air will be lost, and your heater will have to work harder to warm your house. Ducts can suffer damage due to poor installation, pests, mechanical injury or simple old age. When the airflow is constricted, your heater has to overwork in the attempt to warm your home evenly.

Proper insulation and duct repair can help to fix these issues. If your ducts are outdated, you may have to replace them entirely to improve efficiency. Professional technicians can do repair and duct installation.

Keep your heater serviced yearly. This will reduce your energy bills and improve your indoor air quality. Ensure that you have experienced HVAC technicians maintain and repair your system.
