Signs You Need A New HVAC Heating System Installed
When the temperatures drop, your first inclination is to turn on the heat. Perhaps you grab a sweater or a blanket and wait for your home to warm up, and when you notice that the temperature isn't budging, you turn it up again.
Normally, turning up the heat will work, but, when your thermostat says it is warm and your house remains chilly, that’s a sign that something is up and you need to call an HVAC professional.
Heaters that aren’t properly heating could be a sign of a necessary major repair or replacement. But what if you could have prevented this issue?
If you could fend off your HVAC system's damage or disrepair, you could save yourself money and ensure that your heating system runs efficiently.
There are several reasons that your heating system may stop working, and we will explain them below.
There are various reasons why your furnace or heat pump might stop working. Here are the ones you might come across most frequently:
Preventative Maintenance For Your HVAC Heating System
Neglecting your HVAC system is probably the most common of all reasons for your heater breaking down. It is typically the reason your heater isn't turning on. Or, if it is turning on, it’s the reason it is not getting warm enough.
Unfortunately, a few dirty components can lead to a heating system failing to start up, either one element on its own or as a part of a whole.
Usually, all that is required is a cleaning. If you aren't sure how to properly maintain your furnace or heater, or you have just forgotten (it happens), your heating system might be dirty:
Air filters: A dirty air filter limits airflow and causes your HVAC to work harder to push air through the filters. A dirty air filter not only causes damage, but it can also cause low air quality in your home.
The design of air filters will stop many airborne particles from circulating through your ventilation system. It is essential to change your filters every three months to keep your furnace working at its best capacity and to keep your air quality safe.
Blower motor: A dirty blower motor is caused when pollutants, dust, and debris in the air settle on the blower motor. The buildup negatively impacts your heater's efficiency and can lead to expensive repairs.
When the blower motor is dirty, the heat exchanger does not get enough cool air to stop overheating. A dirty blower will also amplify wear and tear on your furnace, causing complete motor failure. Cleaning a blower is a more complicated task than changing your air filter and should always be done by a professional HVAC technician.
Dirty flame sensor: A dirty flame sensor means your heating system cannot light the burners to heat your home. After some time, a flame sensor can get covered in a thick layer of grime.
Your flame sensor will turn off as soon as it is turned on because it needs to do as its name implies—sense the flame—and when it cannot perceive it due to dirt, it malfunctions.
Signs You Need a New HVAC System
If your HVAC system is out of date or working inefficiently, your home may be colder than is comfortable, or you may be exposing your home to dangers in the air.
Keep an eye out for the following signs that your HVAC system is not working properly:
1. Dead Blower Capacitor
When your blower capacitor is not working, you will be able to tell because the blower fan no longer works. You may hear your furnace switch on, but you will not hear the fans running, and there will be no air coming through your vents.
The capacitor is essential to the HVAC system function because it starts your furnace when it gets the signal from your thermostat. Sometimes, a dead blower capacitor won't turn the blower on; a dead blower capacitor can also lead to your blower malfunctioning, which is an expensive repair.
Your HVAC professional will check your capacitor and may catch a failing capacitor before it leads to a costly repair with a maintenance plan.
2. You Are Burning Through Fuel
Upon installing your furnace, your HVAC technician calibrates it to ensure that it will go through an appropriate amount of fuel when turned on. If this is done improperly, a furnace can burn through too much fuel and stop working. This usually happens when you need it most!
Two signs that your furnace has not been appropriately calibrated:
your furnace overheats, causing it to shut off frequently
you have above-average fuel bills. Your furnace may overheat more frequently during frigid temperatures because it can't keep up.
3. Refrigerant Levels are Low
If you heat your home with a heat pump, your refrigerant level can get too low. At this time, your heat strips will turn on more frequently than necessary, leading to high heating bills. If this is something that you have noticed, you will need more refrigerant.
Leaving the refrigerant level for an extended period can cause your compressor to overheat, and replacing refrigerant is less expensive than replacing your compressor.
4. Draft Inducer is Not Working
A draft inducer motor helps eliminate excess fuel in the heat exchanger from the previous heating cycle. It also vents the gases that occur as part of the furnace combusting.
The draft inducer motor can eventually burn out if it is malfunctioning, and it also needs to be cleaned periodically.
5. Your Ductwork is Installed Incorrectly
If your ductwork was installed incorrectly or has any damage due to shifting or general disrepair, it could cause your heating system to become inefficient.
Your heating system will need to work harder to keep your home at a reasonable level of warmth, which means you will have to spend more money to heat your house, and you are putting more wear and tear on your furnace—potentially cutting its lifespan.
6. Dead Heat Pump
Your heat pump failing can stop your blower from starting. Your system, in turn, will not produce heat to keep your home warm and comfortable.
With a maintenance check by your HVAC professional, they may identify heat pump issues before becoming a larger issue, and therefore, you can avoid more expensive repairs.
Is Your Heating System Working?
Issues with your heating system can cause mold growth, dust and debris buildup in your home, and dangerous carbon monoxide.
