Common Issues Affecting HVAC Systems




While today’s HVAC systems are designed to deliver years of dependable service, there are so many things that could go wrong in your HVAC system.

Here are some of the most common HVAC issues homeowners encounter.

Malfunctioning thermostat

If the air conditioning isn’t cooling your house even though it’s running, it’s easy to assume that the issue is with your actual HVAC system. But most of the time, it’s just due to thermostat problems. Try resetting the thermostat to see if this will resolve the problem.

Leaking or low refrigerant

Refrigerant is the chemical that cools the air within your air conditioning system. Low or leaking refrigerant means that your unit will no longer be able to cool the air. The A/C blows air, but the air it produces is not cold.

It is important to address this issue as soon as possible as it causes the condenser to work harder and can lead to bigger, more complicated problems.

Busted fuse

Fuses are designed to protect your unit’s compressor and motor from overheating. The breaker is usually the first thing HVAC professionals check when the HVAC unit shuts off unexpectedly.

Clogged drain

The drain line routes excess water away from the system. Over time, these drain lines collect dirt and become clogged. If this happens, water can back up into the drain pan. This can affect your system’s overall function.

Call a professional and have the drainage system checked and cleaned. This may seem like a minor issue, but if left unchecked, it can cause severe water damage to your home.

Unusual noises

An HVAC unit will make minimal noises when it’s running. But if it started making some unexplained noises, this could be a sign that your HVAC system is failing. There could be an issue within the unit such loose hardware, broken fan etc.
