Understanding When Professional Furnace Repair Is Needed
A furnace may run for years without trouble, but eventually, it will need professional attention. Knowing which furnace problems call for a technician, and which ones can be handled with a quick check, can save time and money. This post covers the signs that furnace repair is needed, troubleshooting steps to try before calling for repair, and how to know when furnace replacement makes the most sense.
Signs Furnace Repair Is Needed
Grinding, booming, or whistling noises are unusual sounds that may signal furnace issues that need repair, since they may mean a part is loose, worn, or failing. Unusual smells like burning are another warning sign of furnace problems and the need for professional heating repair. If the smell resembles rotten eggs, it may indicate a gas leak, so leave the home and contact the gas company immediately.
Inadequate heating can also signal the need for furnace repair. This may show up as weak or cold air coming from the vents or a furnace that can't keep the home at the set temperature. Short cycling, where the furnace runs for only a few minutes at a time before turning off, is another sign of furnace problems. A sudden spike in heating costs with no change in use can mean the furnace is losing efficiency and needs to be inspected.
Things to Check Before Calling for Repair
A few basic checks may solve the problem before a technician is needed. A dirty furnace filter is a common cause of poor heating, so check the filter and replace it if it looks clogged. Then make sure the thermostat is on the heat setting, is set higher than the room temperature, and has working batteries.
Walk through the home to confirm that air vents and registers are open and unblocked. It's also a good idea to check the circuit breaker panel and the furnace power switch, since a tripped breaker or a switch that was turned off will stop the furnace from running. If none of these steps help, call a professional for furnace repair. Avoid opening the furnace or attempting repairs on internal parts, since this can be unsafe and may cause more damage.
When Is Furnace Replacement the Better Option?
Sometimes, a furnace replacement is a more practical option than repair. The age of the furnace is one factor to consider. A furnace older than 15 years is more likely to keep breaking down, and the money spent on repairs may be better put toward a new system.
A furnace that requires frequent repairs or increasingly expensive repairs is also a strong candidate for a new furnace installation. Safety is another concern. A furnace with problems that pose safety risks, such as a cracked heat exchanger, should be replaced rather than repaired. A trusted technician can weigh the condition of the furnace and the cost of heater repair to recommend the best option.
