7 Telltale Signs That an HVAC Unit Needs Professional Repairs

Professional HVAC repairs are vital to keeping your home comfortable during the hot summer or cold winter. And while it might seem like an easy job, a few signs may indicate that you need help.

An HVAC unit is one of the most essential and cost-effective pieces of equipment in any home or office. It provides heating and cooling simultaneously, providing that constant comfort to keep you healthy when working or at home. For an HVAC system to function correctly, it needs regular maintenance from a professional.

1: The System is Not Turning On or Off Properly

All HVAC systems will run smoothly and efficiently for a specific time. But then, over time, they are prone to malfunctions. If your HVAC unit does not turn on or off as it should, that’s a sign that you need professional help. The unit may not be able to turn off properly due to a failure with the thermostat, or it may not turn on at all. The most common reason for this problem is when someone in your home has bumped into the thermostat and turned it to a temperature that is too low or too high. That can cause the system to shut down entirely, but it should kick back once it reaches its preset temperature.

2: Improper Air Distribution

At times, homeowners come to me with issues about the air distribution throughout their homes or office. It could be warm in one area of the house but cool in another part. A common cause of this is a clogged return-air filter. It could also be a problem with the ductwork. Whatever it is, it is best to have an HVAC contractor come and inspect your system thoroughly.

3: Low Air Flow

The airflow needs to be sufficient for air to pass through your system and make the home comfortable. If your HVAC unit is not efficient enough, you will experience excessive hot or cold spots in your home or office. It’s essential to check your HVAC unit during the summer and winter (or anytime during hot or cold temperatures).

4: Excessive Noise

Any noises coming from the unit are not typical, especially if they sound like rattling or wind power that causes vibration and noise. It means that something needs fixing or the team needs to be updated. It’s best to call the HVAC company and talk about the noise problem.

5: Your System is Not Efficient Enough

Your system should operate efficiently and create heat evenly throughout your home or office. If your system needs to be more efficient, you may experience low air flow and excessive noise that will affect your quality of life.

6: Your System is Old and Not Having Upgrades

If your HVAC unit is outdated and has yet to have any upgrades, it needs to be more efficient and robust enough to maintain the temperature in your home. You will have to pay for the unit’s repairs and higher energy costs because the system is inefficient.

7: The Air Delivery System is Blowing Dirt

The air delivery system is one of the biggest causes of Dirt and dust entering your system. That’s why you need to check on your ducts, filters, and blower fans – especially if they’re old.
These signs are vital to take note of and deal with before a costly storm arrives. Getting your HVAC unit serviced by a professional is not only for your sake but for the sake of your comfort and health too. It will be easy to find a good HVAC technician; look for reputable ones in your area.
