HVAC Heat Pump & Blower: How They Function & What Can Be Done When They Malfunction

Posted on: 10 December 2014

There are a few parts of a heating, ventilation and air conditioning (HVAC) system that are vital for energy efficiency. The heat pump and blower must be in a functional condition or you can end up with air that is not true to the temperature on the thermostat circulating in your house. Below, you will learn about the function of a heat pump and blower to an HVAC system and what can be done when they malfunction.

How Does a Heat Pump & Blower Function in an HVAC System?

The heat pump works in an HVAC system to exchange heat within the interior and exterior of your home. The pump is able to help either heat or cool your home based on the temperature you want. If the heater is running, the pump removes cool air in your home and brings in warm air from outside, if available. If you want cold air, the pump removes warm air from the interior and brings in cool air from outside.

The blower is the main part of your HVAC system because no air will flow through the ventilation system without the blower being functional. When you turn the thermostat on, the blower releases air into the ventilation system based on the temperature you set. Dirt can prevent the blower from working completely, or it may simply interfere with how much air it is putting out.

What Can be Done When a Heat Pump & Blower Malfunctions?

If a heat pump fails to remove or bring in air when the HVAC system is running, there may be several things wrong. One problem may be that dirt is covering the pump and it is in need of a professional cleaning. The other problem may be that ice is covering the pump, especially if it has rained or snowed. A specialist can defrost the ice in such a case.

If the HVAC blower is not functioning as it should, the problem is usually due to dirt accumulating. Dirt can cover the blower motor and stall air production until it is cleaned off. Leave the cleaning to a professional because accessing the blower is a complicated task without the right kind of skills.

As soon as you notice a change in the efficiency of your HVAC system, get the heat pump and blower inspected by a specialist to avoid high energy bills. Timely repairs can prevent costly replacements! Contact a company like Nebraska Heating & Air for more information.
