In between professional furnace tune-ups, follow these tips to keep your furnace running strong. Keep your blower motor bearings lubricated throughout the season. If your
heating
system uses oil cups, you should add about 3 drops of oil per year to ensure lubrication. (however, a lot of new motors have permanently sealed bearings and do not need oiling.
)check your blower unit regularly and free it of any dirt. You can do this by vacuuming the furnace periodically. When you do this, make sure you shut off the circuit breaker beforehand. Along with cleaning your furnace, you can also test any exposed ductwork joints for air leaks.
While furnaces can make your home warm and toasty, a system that won’t shut off is a problem, too. If it seems like your furnace is always running, here are a few issues that could be to blame for this common heating problem: thermostat problems. If your heating system isn’t turning off, your thermostat may not be communicating properly with your furnace or heat pump, causing the system to stay engaged in a heating cycle. Thermostat wiring may need to be repaired, or the system may need to be replaced. Limit switch issues. Furnace limit switches may be stuck which makes the blower motor to run around the clock.
4. Inspect your air ducts
Ensuring the vents are open, clean, and clear of obstructions is necessary for even, efficient cooling throughout the home.
However, even with clean vents the airflow can be restricted if the ducts are too dirty. Inspect the air ducts for signs of significant dust, hair, dirt, and debris build-up. You can typically vacuum a short stretch of air ducts , but for longer runs it's recommended to call an hvac maintenance professional to clean the ducts throughout the entire home.
If your heater is unevenly distributing heat throughout your home, your issue could be attributed to two primary things: dirty air filters and inadequate ductwork. Check your air filters for dust and debris and change them accordingly. If your air filters are clean, or if replacing them doesn’t resolve the issue, you may need to inspect your ducts for leaks. Should you find that your ducts need additional work, contact an hvac professional for further inspection.
5. Make sure the gas valve is open
First and foremost, verify that the gas is turned on. You can check this by examining the shut-off valve which is outside. Another easy way to tell if the gas is on and working properly is by starting another gas-burning appliance, like the stove. If it seems like the gas line is not the issue and the gas is flowing to other appliances, check to make sure the gas supply to the furnace itself is open and clear. If the gas supply to the furnace is disrupted, your furnace could potentially be lacking the amount of fuel necessary to ignite.
If your furnace is heated using a pilot light, contact an hvac repair professional to complete the home furnace repair as it could have a number of causes: faulty thermocouple, blocked pilot opening, low flame heat, or even a faulty safety switch—which would require immediate expert attention. An important note: always wait a couple of minutes after turning off the gas valve before relighting the pilot light so a dangerous gas build-up doesn’t occur. The flame sensor of an electric ignition system will shut down your system every time it cannot detect flames, even if it’s just dirty. If your sensor could use a cleanse, turn off the unit power or flip your circuit breaker, shut off the gas, remove the flame sensor or thin metal rod at the burner assembly, carefully rub it on a rough surface, and wipe the sensor before reattaching.
Contents your furnace’s age is undoubtedly a factor, but it is not the only reason you need repair. Relatively new systems can also suffer from neglect and damages. A few of the usual signs that your furnace needs repairs are listed below: gas leaks: turn off your furnace the moment you smell gas permeating around it. The slightest spark can ignite a fire, so do not keep it running. Get in touch with your trusted hvac tech immediately. Inefficient system: an inefficient furnace consumes more energy. Therefore, it is no longer cost-effective. You will notice a gradual or sudden increase in your energy bill when this happens.
