Are you lost as to why your heating, ventilation and air conditioning (HVAC) system has stopped reaching the temperature on the thermostat? When there are both heating and cooling problems from an HVAC system, there are a few different parts that can be the cause. Discover in this article why the HVAC system is not heating or cooling your house efficiently anymore.

There is a Problem with the Air Duct System

When there is inefficiency experienced with heating and cooling your home at the same time, it can mean that there is a problem with air flowing through the duct system. The problem can be as simple as you needing to hire a contractor to clean the air ducts out, especially if you have never had it done before. There might be a lot of dirt or rodent droppings in the air ducts that is creating a blockage and preventing air from flowing to the fullest extent. Rodent carcasses can also be in the ducts if you have a problem with them infesting your house. In the worst case scenario, it is possible that the air ducts are cracked and need to be replaced instead of cleaned.

The Thermostat is Not Working Correctly

If the thermostat to your HVAC system is damaged, it can easily interfere with the efficiency of heating and cooling your home. No matter how good of a condition other parts of the HVAC system are, nothing will work unless the thermostat works. There might be something wrong with the needle in the thermostat, which can cause you to set the temperature inaccurately. A broken thermostat needle can be replaced with a new one if it is the problem. If the entire thermostat is damaged, a contractor can install a new one for you. Your HVAC system should then begin being more efficient.

The System Heat Pump Doesn't Work Right

Although it may seem like a heat pump is only used for warming up your house, it is also used for the air conditioning part of the HVAC system as well. Basically, a heat pump is the part of the system that exchanges warm air between the interior and exterior of your house. The pump is able to bring in warm air from outside when the heater is on (if it's not too cold outside), and can pull warm air out of your house when the air conditioner is on. You might need to get the pump cleaned or replaced. Talk to an HVAC contractor (like Drew Green Heating & Cooling) to find out why your system is so inefficient!
