Having a broken HVAC system on a cold or hot day can be frustrating. An HVAC system that does not work well may also give you high energy and repair costs. Unfortunately, most homeowners do not realize their HVAC system doesn’t work well until a slight problem results in bigger concern.

Identifying and fixing an HVAC problem on time can help prevent HVAC failure at unexpected times. Find out about common HVAC problems. 

Dirty Filters

Over time, dust and other contamination may accumulate on the filters in your HVAC system. Failure to replace dirty filters will have blockages restricting airflow in your HVAC system. Blockages can strain your HVAC system’s blower and cause uneven heating and cooling in your home. Eventually, your entire HVAC system may fail.

Thermostat Failures

Issues such as a misaligned sensor or batteries that have run out of power may cause thermostat malfunctions. A common sign of thermostat malfunction is when you have to reset the thermostat constantly to regulate temperatures in your home. Having an HVAC technician inspect your thermostat can help identify and resolve the causes of thermostat failure. 

Unusual Noises

HVAC systems produce noises while operating. However, some noises may indicate an HVAC problem. For instance, screeching sounds may indicate a motor fan malfunction, while rattling sounds may indicate loose mechanical components. On the other hand, a damaged blower may produce a squealing sound. 

Uneven Heating and Cooling 

Uneven temperatures mean some parts of the home don’t get the heat or cold air they need. Uneven heating and cooling may result from a lack of proper insulation in the house, airflow blockage in your HVAC system, or low fan speed. Consider installing dampers in your HVAC system to regulate airflow. 

Drain Line Clogs

Drain lines drain condensate from your HVAC system to prevent flooding the system and water leaks. Poor HVAC maintenance may result in drain clogs as dust and debris build up in the HVAC system. When an HVAC drain line has a clog, the condensate formed as your air conditioner runs will not drain properly, resulting in further HVAC damage.

Some signs of a drain clog include water leaks, a musty odor from your HVAC system, and signs of water damage near your HVAC unit.

Water Leaks 

As mentioned, water leaks may result from a clogged drain line. You may also observe water leaks from your HVAC system if you have not mounted it at a leveled position.

Constant Operation

Your HVAC system may constantly cycle if its sensor is misaligned. The sensor measures the temperatures coming out of your HVAC system’s evaporator coils. If it touches the coil, it will misread the temperature, causing your HVAC system to run without stopping. The constant operation may also mean that your HVAC system is too small to cater to your home’s volume of heating and cooling. 

Electric Malfunctions

If you have an old HVAC system, the wires and terminals in its electric system may wear out. When this happens, your HVAC system may experience electrical failures. Some parts that electric malfunctions may affect include the HVAC compressor and fans. Damages to these parts will hinder an HVAC system’s functionality.

Refrigerant Leaks

Low refrigerant levels on an HVAC system may indicate a refrigerant leak. If your HVAC system has a refrigerant leak, replenishing its refrigerant is not an adequate solution since it will eventually leak. An HVAC technician can identify and repair a refrigerant leak and add refrigerant to your HVAC system to restore acceptable refrigerant levels. 

You can resolve most of the above HVAC problems by regular maintenance service. Preventative maintenance will also help keep your HVAC system running efficiently. If you have observed any of the above HVAC problems in your system, contact us today for HVAC repairs and maintenance in Colorado.
