Possible Reasons Why Your HVAC Unit Isn’t Working

A steady flow of cool air is essential when trying to keep your home’s interior at a comfortable temperature this summer. Your HVAC unit is responsible for cooling off the air it pumps through the vents in your home. Each year, millions of residential HVAC units break down for several different reasons. When faced with an HVAC unit that simply won’t function, getting it fixed quickly should be your main goal. 

Educating yourself about the various parts your HVAC system has can help you pinpoint the cause of unit malfunctions. Read below to find out about possible reasons why your HVAC unit has stopped working.

A Tripped Circuit Breaker Can Create Big Problems

One of the main things your HVAC unit needs to function is a consistent supply of electricity. Keeping an HVAC unit protected from the damage of an electrical surge is only possible with the help of circuit breakers. These breakers are designed to cut off the flow of electricity to your unit if a power surge occurs. This provides protection to the various electrical components the unit has. 

If your unit cuts off and you can’t get it to come back on, a tripped circuit breaker could be to blame. In some cases, a damaged circuit breaker will trip even when a power surge hasn’t occurred. Allowing professionals to check out the breaker in question is crucial when diagnosing and fixing this problem quickly. 

A Dirty Exterior Unit

Inexperienced homeowners fail to realize just how important the exterior portion of their HVAC unit is. This unit draws in warm air from the outside and then cools it down before it is dispersed through your vents. The metal fins on the outside portion of your unit will become very dirty over the years. Leaving dirt and debris on these metal fins can lead to your HVAC unit getting overworked

These dirty fins will block the flow of air coming into your unit. If a unit is overworked, it may shut down unexpectedly. The best way to prevent this problem is by having the outside portion of your unit cleaned by professionals routinely. 

Low Refrigerant Levels

When warm air is drawn in from the outside, the refrigerant in your HVAC unit is what cools it down. If there is not enough refrigerant in your HVAC unit, it will be nearly impossible to cool the inside of your home down. As soon as you start to notice a lack of cool air, you need to contact the team at KD Mechanical.
