Your HVAC unit may stop circulating warm air for a variety of reasons. Some are simple to inspect and can be done by yourself, while others require the assistance of a professional.
Reasons why HVAC is not Blowing Hot Air
Dirty Air Filters
Air filters accumulate dirt over time and can eventually become clogged. Clogged Air filters can cause significant problems for HVAC units such as furnaces and heat pumps. Professionals recommend replacing air filters after three months. You can find the air filters in return air vents or your air ducts. Filters that are clogged make it impossible for your HVAC system to inhale and distribute air. Some furnaces even have a shutoff that activates when the filter becomes clogged, preventing the furnace from overheating. The furnace will then start blowing cold air. It works as a precautionary measure. Warm air will no longer circulate in your home as a result of this. Filters are inexpensive and simple to replace. If yours is mud-coloured, it’s a dead giveaway that it’s time to replace it. Contact HVAC Cleaning in Buford, GA, for assistance.
Problem with Refrigerant
Furnaces use gas to supply heat, whereas heat pumps use refrigerants. If you have a heat pump that is low on refrigerant, it will not be capable of providing heat to your home sufficiently. Heat pumps consume refrigerant to relocate cool air out of the home during winters. They also circulate warm air throughout the house.
If your heat pump isn’t blowing warm air, the refrigerant may be the issue. It’s possible that the unit is low on refrigerant and needs to be recharged. A refrigerant leak can cause it. It can also cause your home’s humidity to rise, making it feel colder than it should be.
Problem with the Thermostat
Make sure the thermostat is in working condition. The HVAC system will not switch on until the room temperature rises above the temperature you specify.
The first step is to double-check that the thermostat has not been adjusted. Check to see if it’s on auto or heat. Occasionally, a thermostat will be set to cool rather than heat, resulting in the issue. Your heater should turn on as soon as you set it to heat or auto.
Check the batteries in your thermostat if required. Low or dead batteries can also be an issue. Replace the batteries, if needed. If your thermostat is set correctly, but your heater still does not turn on, you may have a defective thermostat.
Ductwork Leaks or Poor Insulation
Poor insulation and a leak in the ductwork can also cause temperature issues in the winter. Heat will not circulate properly throughout the home if the ductwork has leaks in it.
Rooms can also feel colder due to an absence of insulation or poor insulation in the attic or walls. In this case, your heater will have to work harder to keep the room cozy.
If the register or vents of your unit become clogged, your HVAC system won’t be able to circulate warm air if it can’t get enough air.
It’s also important to remember that a vent can close by mistake. Inspect to see if the supply vent is completely open if one room is colder than the others.
When a specific vent is blocked, only the room with that particular vent may feel colder than other rooms in your house. It indicates that there could be a ventilation problem.
According to industry standards, you should perform maintenance twice per year.. For your HVAC unit, this should take place in the spring and fall. Before the weather turns cold, the technician can inspect your HVAC system and make any necessary adjustments or repairs.
It not only keeps your unit operating smoothly but also reduces the risks of future failures and more costly issues.
It will ultimately come to a point where your HVAC unit will be more and more expensive to repair. When this happens, it’s time to think about getting a new system.
Problem with the Condensate Line
The condensate is another part of your HVAC system that needs to be maintained regularly. When your HVAC system is running in the summer heat, the condensing unit regularly drips water into a drip pan. That water is eliminated through piping that leads directly to the outside of your home, where it is discharged. Those lines tend to become clogged with dirt and debris, especially if you don’t maintain them regularly.
