In recent times, Heating, Ventilation, and Air Conditioning (HVAC) systems have become a necessity. We need them to stay cool during summers and warm during winters. They keep us comfortable throughout the year by adjusting the temperature of our homes as per our requirements.
However, sometimes, the sudden temperature changes take a toll on them and they malfunction in the midst of raging summer or freezing winter.
Has this happened with you as well? Has your HVAC in Charleston, SC malfunctioned during the dropping temperatures of winter?
If yes, then, you have chosen the correct source to gather information. Below we have provided the common reasons behind the sudden malfunction of your HVAC in Charleston, SC during winter:
Insufficient Warm Airflow
If your HVAC is not providing the required amount of heat or is unsuccessful in attaining your required temperature, then, this means that your air filter has become dirty. As the name suggests, this component filters the air passing through the HVAC system and entering your home. It removes dust, dirt, pollen, microbes and other contaminants that degrade the indoor air quality of your house. As these particles are stopped by the filter, they accumulate there and obstruct airflow which forces your HVAC to work harder to warm your house.
You can avoid or solve this issue by cleaning or changing the air filter. It only requires a few minutes but, it will save your HVAC in Charleston, SC from further damage to other internal components and enhances the life of your system.
Improper Thermostat Functioning
Thermostats are the major component of an HVAC system. They are responsible to turn your heater unit on and off. If something malfunctions in them, then, you will be devoid of warm air in the freezing winter.
There are a number of things that can go wrong with your thermostat of HVAC in Charleston, SC such as wrong calibration, faulty wiring or dead battery in case of a battery-powered thermostat. The first step that you can take to solve this issue is to change the battery. However, if the problem pertains, then, this means that your HVAC thermostat either requires calibration or there is an issue with the wiring. In both these cases, you should avoid repair attempts on your own and call a professional for help.
Heat Pump Malfunctions
One of the major issues that technicians have noticed in HVAC in Charleston, SC is that the heat pumps don’t turn on during winter. This is because the freezing cold weathers accompanied with snow and chilly winds have a negative impact on the outside component of your system. The fans and coils present inside it freeze and thus, fail to function. The wind carrying the snow deposits it on the various components and as a result, a blockage forms for the fan or a coil.
However, you can avoid these issues by conducting maintenance by an HVAC professional prior to the cold season. He/she will inspect the whole system and identify any glitches that are already present or might arise during the functioning.
Carbon Monoxide Leakage
Carbon monoxide is an odorless and colorless gas and exposure to it can result in death. Studies have shown that every year 400 Americans become a victim of this deadly gas. It can enter and cause havoc in your house as well if you don’t pay proper attention to your HVAC in Charleston, SC.
Carbon monoxide enters a house due to ventilation blockages, rusted or cracked parts in the gas lines or heater and cracked heat exchanger. This can happen if your HVAC system is old and requires replacement. In case of a carbon monoxide gas leakage, you should immediately evacuate the place to avoid poisoning.
Faulty Pilot Light
In some heaters, the full ignition is dependable on the pilot switch. It provides easy access to heat by staying lit at all times. However, if it doesn’t burn brightly or fails to burn at all, then, your heater won’t be able to maintain your required temperature and your house’s environment will be uncomfortable and cold.
This happens because, sometimes, the flame sensor gets dirty and damaged. As a result, the pilot switch misbehaves and, the heater doesn’t fully ignite. You can solve or avoid this issue by properly cleaning the sensor. However, if the problem pertains, then, contact a professional for repair service of HVAC in Charleston, CS.
Sudden Shutdown of Heat
Sometimes during winter, the HVAC system suddenly shuts down even though the power is still on. This happens due to multiple reasons. The first thing that you should check in such a case is a tripped circuit breaker. If that is not an issue, then, it means that either there is an electrical or a thermostat problem. Sometimes, this can also happen because of the pilot switch. In all these cases, you should consult a technician for repair service of HVAC in Charleston, SC to avoid a freezing home during winter.
Continuous On and Off Cycles of Heat
Sometimes, the furnace continuously turns on and off. This can be due to two reasons, either the furnace has malfunctioned or the thermostat requires replacement. In both these issues, you should avoid attempting repairs on your own and call a technical expert for HVAC repair to avoid any further damage.
This issue can also arise due to a clogged air filter. The accumulated dirt and other debris make it difficult for the heater to provide the necessary warm air and the system works harder to attain the required temperature. You can solve this problem by changing the air filter.
