What To Expect From A Furnace Repair Service
Many homeowners wonder where to start when they need to find a furnace repair service. They can often get an idea of what to expect by talking with friends, family members, neighbors and coworkers who have had to use the services of a repair company themselves. It also helps to do a little research on your own, checking the websites of various repair companies and finding out what they charge for.
Many heating system problems are easy to identify and fix, but some require professional attention. We talked to repair technicians to learn which issues generate the most service calls and which can be dealt with by DIYers. We found that most problems stem from clogged furnace filters, or any of three easy-to-fix parts: the igniter, flame sensor and high-limit switch.
The blower motor controls airflow throughout the home both for heating and cooling. If it becomes noisy or ineffective, you may need to clean the blower wheel, indoor coils and secondary heat exchanger. Cleaning these parts reduces friction, preventing overheating and improving efficiency.
Inspecting and adjusting the thermostat is an essential part of any HVAC maintenance plan. Adjusting the thermostat setting allows your furnace to run more efficiently, and will save you money.
When you turn on your furnace, it should begin to circulate warm air through the ductwork and into each room in your house. It is important to make sure the ducts are open and free of obstructions like curtains, furniture, rugs or clothing. If the ducts are blocked, the system won't distribute evenly or work efficiently.
Furnaces depend on electricity to operate, and even natural gas furnaces need a power source to spark combustion and light the flame. If your furnace isn't working, check to make sure the power switch is on and that the circuit breaker isn't tripped.
Most furnaces come equipped with a pilot light. However, sometimes this light can become clogged or otherwise damaged, which will cause the unit to stop functioning. A clogged pilot light can be caused by a number of issues, including dirt, pet hair and other contaminants. You can clean a clogged pilot light with a wire brush or vacuum cleaner attachment, but it's best to call in a professional for any other problems.
Every forced-air duct system requires a filter. The filter should be replaced regularly to prevent impediments that restrict airflow and shorten the life of the equipment. If you're unsure which type of filter to buy, look for one with an arrow on the label that indicates which direction it must face in the ductwork.
During routine maintenance, a technician will examine the heat exchanger for cracks or other irregularities. These problems should be spotted early, as they can be a fire hazard and result in carbon monoxide leaks. While you can do your part to maintain a safe, efficient furnace, a yearly inspection by a professional is the best way to catch any problems early and avoid costly repairs later.
