5 Most Common HVAC Problems in the Home

As a homeowner, you always want to make sure you’re keeping your family comfortable inside the house. Unfortunately, things go wrong and common HVAC problems can always arise. 

Thankfully, none of these issues are too serious and you can resolve many of them on your own. Here are five of the most common HVAC problems you’ll encounter as a homeowner. 

1. Noticeable Reduction in Efficiency

One of the most common HVAC problems is a noticeable reduction in efficiency. This can manifest in a number of ways, including higher energy bills, longer run times, and reduced heating or cooling capacity. 

Some possible causes of reduced efficiency include dirty air filters, blocked ducts, refrigerant leaks, and a malfunctioning compressor. 

To fix this problem, you can start by checking and replacing your air filter regularly, cleaning your ducts, and scheduling regular maintenance for your HVAC system

A lot of homeowners don’t realize they’re supposed to get their HVAC system serviced every year. This is what leads to long-term damage and reduced efficiency. An HVAC tune-up is a great way to keep your system running smoothly.

2. Malfunctioning Thermostat

Another common HVAC problem is a malfunctioning thermostat. If your thermostat isn’t working properly, it can result in inconsistent temperatures throughout your home. This can be caused by a faulty sensor, dead batteries, or wiring issues.

The best way to fix this is by first checking the batteries, then resetting it. If the problem continues, this is an issue where it might be best to call in a professional.

3. Uneven Temperature Distribution

If you’re noticing that certain rooms in the house are always warm while other areas are always cold, this could be the result of uneven heating throughout the home. 

A number of factors including a bad thermostat, blocked vents, and poor insulation can cause this. 

You’ll want to start by checking the vents and air filters yourself. In many cases, however, you’ll need to hire a professional to inspect the ductwork and provide more complex solutions.

4. Squealing and Screeching

If you hear unusual sounds coming from your HVAC system, such as squealing or screeching, as American Home Shield explains, it may be a sign of a more serious problem. This could indicate a damaged fan belt, malfunctioning motor, or a failing compressor. 

To fix this problem, you should immediately turn off your system and call in a professional to diagnose and repair your HVAC.

5. Blown Fuse/Tripped Breakers

If your HVAC system has suddenly stopped and is not coming back on, you’ll want to check your breakers. This will occur when the system is overloaded or if there is an electrical issue with the wiring that is causing the breaker to trip. 

You can try resetting the breaker. If the issue continues to happen, you’ll want to call a professional immediately to look at it.

What Causes an HVAC Thermostat to Fail?

One of the most common HVAC problems is a failing thermostat. There are several reasons why this can happen:

  • Age: The age of your thermostat will obviously impact its performance. A thermostat will last around 10 years. If yours is approaching that age, it might be time for a replacement.
  • Electrical Issues: Faulty wiring, short circuits, and power surges can cause damage to the thermostat’s electrical components, leading to failure.
  • Dirty or Clogged Components: Accumulation of dust, debris, or dirt on the thermostat components, especially the sensor, can affect its performance and cause it to fail.
  • Incorrect Installation: If the thermostat or wiring isn’t properly installed, it can lead to damage to thermostat components or improper function. If the thermostat was recently installed and isn’t working at all, this is likely the issue. 
  • Battery Issues: If your thermostat is battery-operated and not hardwired, you’ll have the check the batteries every few months. If the batteries are dead or worn down, it can cause the HVAC system to malfunction or not turn on when it should.

What Are The Five Factors That Affect HVAC Comfort?

If you know how to diagnose HVAC problems, you’re less likely to have to suffer through HVAC issues. Here are five of the most important factors that impact the performance of your HVAC system:

  • Temperature: Temperature is obvious. Without a comfortable temperature in your home, you can’t enjoy yourself. If the HVAC system isn’t working properly, you won’t be able to have a comfortable temperature. 
  • Humidity: The amount of moisture in the air will impact your comfort. High humidity causes a warmer and more muggy environment while low humidity causes dryness. 
  • Airflow: Your HVAC system should ensure proper air circulation throughout the home to maintain consistent temperatures. 
  • Air Quality: Many HVAC systems help to filter contaminants and keep them out of the house. 
  • Noise: HVAC systems that are loud or produce annoying sounds can be distracting and impact comfort levels. Quiet and unobtrusive HVAC systems are ideal for creating a comfortable environment.
