Common Issues Detected During an HVAC Inspection

When we think of getting our home inspected, it’s easy to overlook our HVAC system. While it’s true that the heating, ventilation, and air conditioning system is a major expense to maintain and repair, an HVAC inspection can help you avoid future and costly repairs. A comprehensive HVAC inspection by an experienced and certified inspector will save you money and energy costs in the long run!

When it comes to home inspections, the HVAC system is often one of the last things people think about. After all, it’s not like other parts of the house don’t have issues. Things like electrical concerns, plumbing issues, and structural integrity are all important topics in a regular home inspection. But the HVAC system is just as important because it affects the overall comfort of your home.

A thorough HVAC inspection can detect a wide range of potential issues. Some of the most common issues that can be found during an HVAC inspection include:

1. Unpleasant Odors

Unpleasant odors can indicate there is an air quality issue in your home. If you've noticed an unpleasant smell coming from the vents or around the HVAC system, it could be a sign of a larger problem.

2. Clogged Air Filter

Dirty and clogged air filters can decrease the efficiency of your HVAC system, leading to higher energy and cooling costs. If left unchecked, a clogged air filter can also cause the system to overheat and ultimately lead to a breakdown.

3. Poor Airflow

Poor airflow is often caused by a dirty air filter or clogged air ducts, and this can have several negative effects. For one, when airflow is limited, the efficiency of a home's air conditioning and heating system is diminished, meaning the system will have to run longer and operate at a higher capacity in order to heat or cool the home. 

4. Inefficient Blowers 

The blower fan is responsible for pushing hot and cold air throughout your home, so it’s essential that it’s working as it should. During the inspection, the technician will check to make sure the blower fan is running at the right speed and pressure and make sure there aren’t any small pieces of debris obstructing the fan. 

5. Weak or Inadequate Insulation

If your insulation isn't properly maintained, you'll lose energy and money due to wasted energy. Poor insulation also causes your HVAC system to work harder to maintain the desired temperature, leading to higher energy costs.

6. Loud Noises

Loud noises from your HVAC system can indicate there is a mechanical issue or something is amiss. If you hear strange rattling, buzzing, hammering noises, or other odd sounds it’s important to have a certified HVAC inspector take a look.

7. Electrical Issues

Electrical problems can be dangerous, especially when it comes to your HVAC system. Electrical issues like old wiring, frayed cords, and blown fuses can all be found during an HVAC inspection and addressed before they lead to a potential disaster.

8. Refrigerant Leaks 

Another common issue that can be detected during an HVAC inspection is a refrigerant leak. Refrigerant is what helps to cool the air, so when there is a leak, your HVAC system won’t be able to cool the air properly. The technician will look for any signs of a refrigerant leak, such as acid deposits near the evaporator coils or hissing noises near the line. 

9. Malfunctioning Compressor 

The compressor is the heart of your HVAC system and is responsible for pumping refrigerant throughout the system. If the compressor is malfunctioning, it can cause issues such as inadequate cooling and an increase in your energy bills. The technician will check the compressor and make sure it is functioning properly and has the right levels of refrigerant.

These are just a few of the potential issues that can be detected during an HVAC inspection. A thorough inspection by a certified HVAC inspector can also reveal issues such as faulty or aging components or damaged air ducts that may be letting in outside air.

No matter what type of HVAC system you have, it is important to have it inspected regularly. A certified home inspector will be able to spot potential issues before they become more serious, costly problems. Preventative maintenance and regular inspections are the best way to ensure your HVAC system is running efficiently and safely.
