7 Common HVAC Problems That Homeowners Deal With

VWB Blog 1 year ago 15

When your HVAC system is acting up, it’s not a matter of simply replacing a part. Not only is it time-consuming, but it gets to be very expensive.

We all have to take care of our heating and cooling systems. Learning common HVAC problems leads us to solve them quickly before they escalate.

If you’re wondering how to keep your home heating system in good condition, keep reading to know what problems to address.

1. Signs of Insufficient Maintenance

Insufficient maintenance is one of the common HVAC problems that homeowners face. Dust and other particles get inside the air vents, reducing their efficacy, and this can cause the system to fail prematurely. The compressor and blower fan can become overly dirty, leading to an inefficient HVAC system.

Other problems include clogged filters, loose connections, and valve leaks. Homeowners should have their HVAC system regularly serviced and make sure to keep the filters, fins, and other components clean.

This will allow the air conditioner to operate more efficiently, prolonging its life span and increasing home comfort. An HVAC system that is regularly maintained will run more effectively and efficiently, ensuring the comfort of a home while reducing wasteful energy usage.

2. Thermostat Malfunction

If the thermostat malfunctions, the heating and cooling system won’t turn on, or it won’t turn off when it’s supposed to. The thermostat may be faulty or not correctly calibrated, making it difficult to get the right temperature. Other thermostat issues could be a power supply problem or the thermostat may get stuck on one setting or go haywire, changing the settings constantly.

In addition, if the thermostat is old it may be time to upgrade which can help keep the right temperature and easily adjust the settings. Homeowners should be aware of these common malfunctions and keep an eye on the thermostat at all times. If there are any issues, repair or replacement of the thermostat should be done promptly to avoid further damage or cost.

3. Airflow Issues

HVAC systems are often subject to a variety of issues over the years, especially if they are not serviced regularly. Common HVAC problems related to airflow issues can include:

  • an unclean air filter
  • blocked vents or air ducts
  • an overworked blower motor

Air Filters

Clogs in the air filter can reduce the flow of air, resulting in poor air quality due to dust, dirt, and other contaminants. Blocked air ducts can cause restricted airflow, resulting in uneven cooling or heating throughout the home.

Air Ducts

Leaking air ducts on the other hand can lead to HVAC malfunction. That is why it helps for you to learn more about air duct sealing.

Blower Motors

Overworked blower motors can cause reduced airflow due to the lack of air pressure needed to properly distribute cool or warm air. It is important to have an HVAC technician address airflow issues quickly.

4. Refrigerant Leaks

Refrigerant leaks can cause HVAC systems to malfunction and result in decreased energy efficiency. It can also cause wear and tear on components and can lead to further damage if not addressed quickly. Several signs may indicate a refrigerant leak, including:

  • weak airflow
  • higher energy bills
  • warmer air than normal
  • unusual noises

To identify and repair a refrigerant leak, homeowners should contact a certified technician to inspect and repair the system. The technician will use tools such as HVAC leak detectors to detect and repair the leak.

If the refrigerant is simply low, the technician may be able to add more refrigerant and restore the system to working order. If the refrigerant is leaking, a technician may have to replace components or perform repairs to ensure the system is operating properly.

5. Noisy Operation

Noisy operation is a common HVAC problem that homeowners deal with, and it can be caused by several different issues. One potential cause is insufficient maintenance; when air filters get clogged, or when other components are not properly cleaned or replaced, they can create rattling and buzzing noises.

Loose nuts and bolts and worn fan belts can also cause excessive noise, as can vibrating and poorly installed ductwork. If the system age is getting to be over 15 years then deterioration can be the cause of the noise.

If the unit is not the correct size for the home, airflow can become obstructed, leading to a noisy operation. Depending on the cause, noise levels can vary, so it’s important to consult an HVAC professional to diagnose and resolve the issue.

6. Electrical Problems

If the HVAC system is wired improperly, it may result in utility line overloads or system damage, leading to major repair bills. Broken circuit breakers or blown fuses, non-functioning contactors, wiring problems such as exposed or frayed electrical wiring, and voltage or current imbalances are the most common electrical issues seen in HVAC systems.

Homeowners may also experience frequent copper corrosion or rusting in the electrical components of their HVAC system, which may lead to poor operation and loss of efficiency. These problems must be taken seriously to prevent further damage and costly repairs. Regular servicing of the HVAC system can help mitigate the effects of electrical issues.

7. Uneven Heating or Cooling

Uneven heating or cooling is a common problem faced by homeowners when it comes to HVAC systems. This issue is typically due to a disproportionate distribution of energy to certain rooms or floors of a dwelling. It can be caused by a range of factors, including:

  • blocked airflow
  • individual room temperature settings
  • window and door placement
  • insulation issues

To resolve the issue, homeowners should ensure that vents are free of debris, windows, and doors are properly sealed, and any insulation is in good condition. For further help, homeowners should ask a professional to assess these areas and to help locate any hidden leaks or blockages that may be impeding the flow of air. In some cases, a complete reconfiguration of the HVAC system may be necessary to ensure even heating and cooling throughout the entire home.

Be Prepared for Common HVAC Problems

Common HVAC problems can be expensive and disruptive. Therefore, it is important for homeowners to be familiar with signs of problems with their system and to schedule routine maintenance to head off potential problems.

If you are facing HVAC issues, contact a professional to help you address the problem and get your HVAC unit running efficiently.
