Major Causes Of Broken HVAC Units

One of the worst feelings in the world is when you go to turn on your HVAC unit on a hot summer day and nothing happens.

A broken HVAC unit can have many causes, and here are five of the most common you should watch out for.

Maintenance Breakdown

Not keeping your Seattle HVAC unit maintained is one of the most common causes of breakdowns.

This could be caused by a failure to change the filter or a failure to have the unit serviced regularly.

Having a certified HVAC tech inspect and service your unit each year can ensure any problems are caught and fixed before they cause the entire unit to fail.

Refrigerant Leak

Your HVAC unit uses a chemical refrigerant that allows it to cool the air it pumps into your home. If this refrigerant runs too low or runs out altogether due to a leak or some other problem, your unit will push out air that isn’t cooled enough or at all, which will make it unable to do its job properly.

Broken Thermostat

Your home’s thermostat is what tells it when to kick in and how long to work until your home is cooled to the right temperature. If the thermostat is not functioning properly, your unit won’t work correctly.

If the thermostat doesn’t work at all, your unit won’t turn on. If it is malfunctioning, your unit might kick on at the wrong temperature and then run too long or not long enough.

Sensor Issues

In addition to the thermostat, your Seattle home also has an HVAC sensor. If the sensor is not working properly or at all, your HVAC unit may not know when to come on or when to turn off, which can mean it doesn’t cool your house properly.

Condenser Coil Problems

The part of your HVAC unit that sits outside your home contains your unit’s condenser coil, which deals with the hot air your HVAC unit circulates out of your home.

If it gets clogged with dirt or debris, it won’t work properly and your home won’t cool down the way it should. You can fix the problem by spraying down the unit with a hose. If conditions don’t improve after you do that, then you may have a bigger problem that needs the attention of an HVAC technician.
