10 Commonest Heating System Problems & How to Fix
Most of us wish to be comfortable within our homes if the temperatures dip. Despite you not requiring to run your heating system too frequently you must ensure that it’s running efficiently and in good condition with the approach of the winter months.
That’s why it’s necessary to get your heating maintenance in California before the weather turns chilly. Let’s analyze 10 of the commonest issues you could experience with your heating system and the ideal methods to fix them.
The Heating System Won’t Switch Off
Once your heating system continues to run and blow hot air, you initially have to check whether it’s set on “auto,” instead of “on.” By being on “auto,” your heating system will go off as it reaches its set temperature.
If it continues to run after this step, your thermostat might be broken or wired inappropriately. It could be a problem too with your heating system’s blower. Ensure the wiring is plugged in properly in the thermostat and then reset it to the manufacturer’s settings to observe the system running. If this doesn’t work, you may require heating replacement in California.
Parts of Your Property Not Heating Adequately
If your house is not being uniformly heated throughout, it may lead to a dirty air filter or issues with your ductwork or the fan motor of the heating system, bearings, or belts. Replacement of your air filter is a simple solution. However, if there are issues with your ductwork or system, contact a technician.
Cool Air Discharging Out of the Vents
If you have a heat pump or furnace, the central heating system in your home distributes heat throughout your home through a chain of linked air ducts. Despite the possibility of leaky ducts affecting the temperature of the air releasing from your vents, there are a few quick solutions that need to be addressed.
Thermostat — Check if the thermostat is set at the right temperature. See the temperature difference. The thermostat should be set on “auto,” instead of “fan on,” as the fan will simply blow non-heated air.
Air Filter — Air filters must be replaced every one to three months as they accumulate lots of dirt and debris.
Pilot Light — Check the heating system’s pilot light to find if it’s lit. If not, there might not be gas flowing to it. If the gas valve is off, that could be the issue.
Fuel — Irrespective of whether you have an electric, gas, or oil heating system, it must have enough juice to run well and will be more useless if it doesn’t.
Air Ducts — A simple way to check leaky ducts is by turning on your fan and then going up to your crawl space or attic. Walk along your ductwork to feel some blowing air. If you don’t observe anything, you can cautiously light a piece of incense and hold it close to one of the junction points joints to notice if the smoke blows away from the ductwork, establishing a leak.
The Heating System Doesn’t Light Or Stay Lit
If your heater is new, it most possibly applies electronic ignition and features an intermittent pilot light, instead of a conventional pilot light. Often the sensors that ensure that gas isn’t flowing while the heater isn’t on become dirty and must be cleaned or replaced.
The Thermostat Controls Aren’t Functioning
If you face issues setting the temperature or changing the system controls, your thermostat could be the issue again. If you own a digital thermostat, attempt replacing the batteries. If it doesn’t work, you can again try resetting it to the manufacturer’s settings.
Check if there’s a tripped circuit. Finally, you can check the wiring again.
The Heating System’s Fan Isn’t Functioning
If your heating system’s fan isn’t functioning, you should first check the thermostat if it’s on the correct setting. Then, check your air filter so that it’s not dirty. Often an extremely dirty air filter can prevent your fan from working.
Do check whether your circuit breakers are on. If not, switch them on, but refrain from switching them on and off repeatedly as that could lead to an electrical fire.
Mold in the Heating System
Moisture accumulation within your home’s heating system can be a challenge, especially due to low-quality insulation or faulty ductwork. In such a scenario, mold can grow in your heating system.
Also, it’ll be a good idea to replace your air filters every one to three months and get your air ducts professionally cleaned every few years.
A Burning Smell Coming from the Heating System
Once you switch your heat on for the first time in winter, there could be a burning smell as the heating system is burning away all accumulated dust and dirt since the last time you used it.
Also, it could be due to a dirty air filter. But it could be a more serious problem if the smell persists. Switch off your heating system and unplug it quickly. After unplugging, clean any dust or dirt that has piled up and change your air filter if required.
Your Energy Bills Are High
Many houses have heat pumps, instead of furnaces, and often energy bills can rise during the winter due to any number of minor issues, including a dirty air filter or tripped breaker. The problem could be due to a damaged compressor or refrigerant leak.
Lack of Maintenance
If you don’t regularly maintain your heating system, problems like higher energy bills and premature repairs can arise. Scheduling a heating repair service in California will eradicate any minor issues before they become big problems.
Ensure that everything is in proper running condition before winter. You may require repair or replacement of your heating system if you ignore it.
