DIY Furnace Troubleshooting & Repairs
If your home is heated with a forced-air heating system, a furnace or a heat pump is the heater at the heart of it. Here we look at how to handle furnace problems from a furnace working poorly to a heater not working at all. For heat pump problems, see Heat Pump Troubleshooting & Repairs.
Though forced-air furnaces are normally quite reliable, they can break down. To avoid break downs, it pays to know how to maintain your furnace and fix it when something goes wrong.
Inevitably, a furnace stops working when you need it most. Consequently, fixing becomes urgent very quickly.
The following instructions will help you do the fixing—or at least figure out what needs to be fixed. With a little do-it-yourself experience and the proper guidance, you can troubleshoot and repair a variety of furnace problems yourself.
General Furnace Maintenance
If possible, also slide out the fan unit, clean each fan blade with a toothbrush, and then vacuum with a brush attachment on a vacuum cleaner.
While you’re at it, look for oil ports on the motor, normally located near the motor shaft. If the motor has these, apply two to three drops of non-detergent motor oil into each port (you may have to remove a cover plate to do this). Though most contemporary motors don’t require lubrication, motors with oil ports should be lubricated once a year. For more about maintenance, see Maintenance Checklist for Central Heating Systems.
Gas Leak
If you suspect a furnace gas leak, deal with this immediately!
First, if you smell natural gas in your home or near the furnace, do not light any matches or turn off or on any switches. If the gas odor is strong, immediately evacuate your house, leaving the door open.
Hand and wrench turning off a home's gas supply valve.
To shut off the gas supply to your home, turn the valve until it rests perpendicular to the supply pipe (here the gas is on).
Turn off the gas supply valve, typically located by your gas meter on the gas inlet pipe.
Turn off the gas by rotating the valve one quarter turn with an adjustable wrench.
When the gas is off, the valve’s oblong stem points perpendicular to the inlet pipe. Then call your gas utility or the fire department from a remote location. Do not return to your home until you know it is safe.
Ways To Avoid High Heating Repair Costs
There are many ways to maintain your heating system. Odds are, during winter months your heater is on all day attempting to keep the home warm. Actually, it is usually on more than it must be because it is unable to maintain an operable environment. When trouble shooting and optimizingyour heating segment of your heating system, there are several areas to examine.
The Air Filter
This is what you usually hear people speaking about most often, but so few people take the recommendation and check it. If there is a obstruction, you either run the chance of not circulating heat adequately or possibly igniting a fire.When the air filter is dirty air will not flow through either which means the unit must work overtime and will also mean a risk of fire. When your system works too much, it costs more to run. The fire situation is self-explanatory. In each case it is not good for peace of mind or your finances.
Look At The Blower
Have a look at the blower blades to ensure they are clean. A dirty fan will work harder to blow air around and of course use more energy to maintain the thermostat level you choose it at. This means the system is overworking and costing extra money to run.
Fire Damper Function
Next, focus on the fire damper to make sure it is running acceptably. The fire damper is self-explanatory so pay attention to this aspect.
Look For Holes In The Flex Duct
It is feasible that your ducts have become impaired over the years for a variety of reasons. If there are obstructions or if the duct has collapsed anywhere the heating system will think the correct temperature has been achieved, which will be wrong. When this will happen the system works harder to do its job but is going to be incapable to attain the right temperature range.
Band Insulation
Insulation is often overlooked but is among the most frequent reasons why an heating system malfunctions. Be sure to check the insulation and verify it has never become loose and resulted in gaps involving the ductwork and of course the outside. When this happens furnace works more than wanted while trying to reach the best temperature.
Air Ducts Need To Be Sealed
See that your ductwork does not become detached from the next section. These detachments may cause gaps in the circulation and cause a loss of hot air in your home, since it is going to be getting out through the gaps.
Return Air Inlets
Ensure that return air intakes are free of the dust and dirt so air can flow easliy.
The Zone Dampers
Look at the zone dampers to check if they are in the right place. Throughout the year we could change the positioning of the damper for many reasons (i.e. getting in a tight space or arranging for storage). Check to see that the dampers are in the correct position too. If you need a professional to look at your furnace click here furnace repair
