How to Troubleshoot Your HVAC System: Tips and Most Common Problems

Customers often report that there were signs that something was wrong before their HVAC unit suffered a total breakdown. It is important for homeowners to recognize these issues with their HVAC systems before this extensive damage occurs.

Many HVAC issues may only require a simple fix, while others require a professional technician to perform an evaluation, diagnosis, and repair.

The following informational guide will examine the most common HVAC problems reported by Florida homeowners. It will also reveal tips to help home homeowners troubleshoot their HVAC systems and prevent a total breakdown.

A/C Not Turning On

If the temperature setting on the thermostat indicates that the system should be on, but the unit still refuses to engage, there may be an issue with the thermostat or electrical wiring.

Check the circuit breakers to make sure that it is not a simple power issue. Contact an HVAC technician if resetting the breaker does not correct the issue.

Blowing Hot Air

There are a number of reasons that your system could be blowing hot air or air that doesn’t feel as cool as it should. This may be an issue with the refrigerant levels or a belt that needs to be replaced.

Examine the area around your unit to check to see if any leaks are present. A bigger issue may exist if the unit is leaking refrigerant or water. Contact a technician to identify the cause of this issue before extensive damage occurs.

Refrigerant Leaks

 

Excessive water and/refrigerant around the HVAC unit may indicate an issue with the drainage pipes or a damaged pump. This can cause severe damage to the unit.

Turn off the unit and contact a professional immediately to avoid costly repairs, including a system replacement.

Tripping Circuit Breaker

An A/C unit that is improperly installed may repeatedly trip the circuit breaker. This may indicate the home was not properly wired for the unit’s energy requirements.

Homeowners should never attempt to solve electrical issues on their own. Always contact a trained professional to evaluate, diagnose, and correct this issue.

Constant Running

Should I turn my ac off?

Even in warmer weather, the unit should turn off periodically. An HVAC unit that runs constantly never gets the opportunity to rest, overworking, and potentially damaging important system components.

Check the vents and air filters to make sure that they are not clogged. If these issues are not the cause, the thermostat or an electrical problem may be present. A professional technician will need to investigate and determine the issue.

Frozen Coils

Frozen coils indicate the HVAC system is working harder than it should be to keep the home cool. This may be an issue with the fan, air ducts, or unit components.

A professional will need to diagnosis the cause of this issue.

Noise

why is my AC making noise?

Odd noises, including screeching or grinding, may warn homeowners that an issue is present. These issues may indicate that a simple repair, such as a belt replacement, is needed. If grinding is present, there may be a more serious issue to blame, including issues with motor, bearings, or another system part.

Odd noises coming from the unit can indicate serious issues that require immediate professional assistance. Contact an HVAC technician immediately before the system is irreparable.

Importance of Air Filter Replacement

Should I change my AC filter ?

Replacing all air filters is the first thing homeowners should do if their system is not operating correctly. Many of these common A/C issues can be a result of a dirty air filter. Filters should be examined on a monthly basis and replaced as needed. Neglecting to replace air filters causes the HVAC system to overwork, underperform, and increase the risk of costly repairs.

Avoid Costly Repairs

How to Troubleshoot Your HVAC System

It is imperative that you contact an experienced, reputable HVAC technician if your system is not operating properly. Continuing to operate an ill-functioning system can overwork the unit and result in a total system breakdown.

A yearly inspection and tune-up may also prevent many of these issues from occurring. A trained HVAC technician can evaluate the unit, check for leaks, loose screws, clogs, etc. This preventative maintenance is a crucial element in ensuring that an HVAC unit continues to operate at its optimal performance capabilities.
