8 Signs Of HVAC System Failure

You depend on your heating system to maintain safety and comfort in your home throughout the cold months of winter. Regardless of whether you have installed a heat pump or gas furnace, it is important to have a healthy and working system. This will ensure that you continue to enjoy efficient heating and good quality indoor air, something that is good for your health.

Heating systems can develop problems without warning and inconvenience. Timely repair or replacement of the system is determined by how soon you realize that the unit has a problem. Therefore, ensure that your system is in top-notch condition to avoid going through the coldest months of the year without heat.

In this article, we have listed 8 signs of heating system failure, therefore, helping you identify them and contact a professional HVAC contractor on time.

1. Abnormal Sounds

Your heating system runs with minimal noise when in good shape. But when you notice a spike in the noise, or you hear an unfamiliar one, don’t waste time and contact a heating system professional to come over and have a look. He or she will investigate the source of the abnormal noise and advise on the next course of action.

Broken components and build-up of dirt and debris are some of the common causes of noise changes. If left unchecked, they may lead to major problems that are expensive to remedy. Therefore, it is vital that you have the noise checked and addressed as soon as possible.


2. Constant Cycling

Modern heating units are designed to automatically switch on and off depending on temperature changes. The unit should stop blowing hot air once your home reaches the right temperature and automatically resume blowing the air when the temperature shifts.

A system turning on and off continuously without any break in between is a sign that it is becoming inefficient. This may indicate that the unit is undersized, it has a damaged compressor, or it needs professional cleaning.

3. Excessive Condensation on Windows

Other than blowing warm air in your home, the heating system also helps in regulating moisture in the air. However, it does this to a small degree. But if you notice high levels of condensation on your glass doors or windows, contact your HVAC contractor because this indicates a problem.

4. Frequent Need to Adjust Settings

You should be able to change the temperature settings on your system at the beginning of the day and at night, without changing it multiple times in between, if you have a good heating unit.

Your system has an efficiency problem if you have to change its settings constantly to achieve a comfortable, and you should have it checked and repaired.

5. High Power Bills

Heating systems are likely to become ineffective as they age. As a result of the declining efficiency, the system will have to work harder to achieve the same level of efficiency in producing heat it did before. You will begin to notice increased need to constantly adjust the temperature settings, extra cycling, and an increase in your energy bills.

To confirm whether or not your bill has spiked, compare your current bill with those of previous years. After confirming this, the only reasonable thing to do is to upgrade your heating system.

6. History of Frequent Repairs

If the frequency of your heating system’s repairs has increased, it is an indication that the unit is about to fail. Even though these repairs will take care of small issues, you have to start thinking about replacing the system with a new one if they become too much. There are many replacement options and your contractor will help you make a good choice. The cost of buying a replacement unit might be scary, but you will come to notice that installing the new unit is a smarter investment than continuously covering repair costs.

7. Poor Indoor Air Quality

Many problems that heating systems develop are a product of these systems sitting idle for a huge chunk of the year. During this period, these machines gather a lot of dirt, dust, and debris. Consider cleaning your unit when you notice an increase in dustiness or dust blowing through your home. You might also need to do some repairs to the system if it has been sitting dormant for a long time as some of its internal components may have corroded due to grime.

8. Room-to-Room Temperature Changes

You should experience consistency in each room’s temperature, with minimal fluctuations around doors and windows in your home, unless the system you are using is a zoned one. But if you notice inconsistent temperature in different rooms in your home, then the heating system you are using might be too small to efficiently provide heated air throughout your home. Another sign that the system is not suitable for your home is significant drafts and sudden changes in temperature in the house. A good HVAC contractor will recommend a suitable replacement based on the measurements he or she takes from your home.
