If your home’s heater repair system suddenly stops working, you may feel like you have a major problem. But that doesn’t mean you have to live in an uncomfortably cold house, especially if it could be easily fixed.

What are 4 examples of heat?

The most common cause of a malfunctioning heater is improper maintenance. A yearly inspection and tune-up can help prevent problems from happening in the first place.

You’ll also find that a regularly-scheduled furnace repair service saves you money. A properly maintained heating system can last for 10 to 20 years, depending on the type of unit.

Some homeowners don’t realize that regular inspections can increase energy efficiency and extend a unit’s lifespan. They can also improve indoor air quality.

A lack of proper air flow can be a sign that your ductwork is blocked or the ducts are not correctly sized. A professional HVAC technician will inspect the duct work to ensure that it is free of damage or obstructions.

Low or stale odors are another sign that your heater needs to be repaired. These odors could be a result of biological growth inside the furnace, which is a good reason to get it inspected by an experienced HVAC pro.

Bad smells can also indicate a problem with your ductwork or air filter. If you have children or pets, a stale odor isn’t only unpleasant but can also cause respiratory illnesses.

A clunking, screeching or banging noise is also a sign that you need to call a heating repair company. These sounds can be caused by a loose motor bearing, a broken fan or even an improperly fitted air filter.
