On cold winter days, only a few things can disappoint you more than a heating system that’s blowing cold air. At times, the blower of your heater will switch on immediately to cause the vents to emit cold air before the air is fully heated by the furnace. If this cold air does not warm up even after an hour of switching the heater, then you may have a serious problem at hand. This is one of those problems that can only be fixed by a someone who can professionally perform heating and air conditioning repair in Rockwall, TX.
From ductwork that has not been maintained properly to a thermostat that hasn’t been set appropriately, several different things can cause your heater to blow cold air. While you should let a heating and air condition service in Rockwall, TX handle the problem, you have all the right to know what’s causing your heater to blow cold air. Here are some potential causes of the above problem with your heater.
Problems with Your Thermostat
If your heater is blowing cold air, then you may want to check your thermostat. Programmable, modern day thermostats can have multiple settings. The thermostat is often the cause of your heater blowing cold air. For this, reason, you should verify the temperature and ensure your system is set to heat. Regardless of the type of HVAC system you have, you should check your thermostat if your heater starts to blow cold air. So, if the thermostat has been set appropriately but your heater still blows cold air, then you may have to call in a service that performs heating and ac repair in Rockwall, TX. Since warm air does not come out immediately after you turn on the heater, ensure that you wait a few minutes before making any conclusions.
Problems with The Ductwork
Heat exchange won’t occur instantly whether you have a gas or electric heater. After you turn on the heater, it will take some time for the heated air to move throughout your home. After collecting and compressing the air in your home, your heater will heat it and then it will evict the cold air. To ensure that your HVAC expels the cold air outside, heating systems operate by heat exchange. Before the heater can warm up home successfully, this process must be completed a few times.
Your heater’s initial heating time is likely to extend if its ductwork has poor insulation. As they push the air throughout your home, the airways via which the heat travels should be able to maintain the temperature of the air. Ensure that hot air is flowing in your home within a few minutes. If that does not happen, call in a heating and air condition service in Rockwall, TX.
Problems with Your Electric Panel
Regardless of the type of HVAC system you have, there is a good chance that your heater requires electricity to run. Several issues in your heater can be caused by just the tripping of a breaker insider your electrical panel including the heater blowing cold air. Your furnace may not turn on at all if a circuit breaker has tripped. Additionally, this can cause your pilot light to remain switched off. Either of these situations can cause your heater to blow cold air. If you’re faced with any of these problems with your electric panel, then you should not try to fix it yourself. Instead, take help from a service that performs heating and air conditioning repair in Rockwall, TX.
You switch on your heater and your furnace starts to blow hot air, then cold air, but after a while it stops blowing air completely. So, what’s causing this problem with your heater? It is likely that your furnace has overheated. When this happens, a furnace safety device called the limit switch has probably turned the furnace burners off. And, to cool the furnace down to a safe level, the blower keeps blowing.
Now, many things can cause the furnace to overheat and one of them is a dirty furnace air filter. By blocking the flow of air and causing your air filter to take longer to heat your home, the dirty air filter will cause your furnace to overheat. While, there are a few DIY solutions to this problem, it is in your best interest to deal with the problem by calling in a service that performs heating and air conditioning repair in Rockwall, TX.
Problem with the Valve
You probably have a malfunctioning gas valve if the pilot light refuses to switch on. Also, you could have a stuck valve caused by dirt and debris if you haven’t cleaned your system in a while. If you notice such a problem with your heater, then call in service that performs heating and ac repair in Rockwall, TX to overcome it.
Problem with the Heat Pumps
Compared to gas and electric furnaces, heat pumps blow colder air due to their design. If the temperature outside is extremely cold, then auxiliary heat strips will be used by the pumps. The heat pump will start to blow cold air if a problem develops in these strips. Similarly, in the warmer months, heat pumps require a certain level of refrigerant. If the level is lower than that, then the pump will not transfer heat efficiently. If your heat pump starts to blow cold air, call in a professional heating and air condition service in Rockwall, TX to have your refrigerant level and heat strips checked.
In addition to the six reasons given above, many other things can cause your heater to blow air. Regardless of what is causing your heater to blow air, you can solve this problem with your heater by getting in touch with K&S Heating and Air in Rockwall, TX today. This is in your own best interest!
