6 Signs You Need a New HVAC System

A home’s heating, ventilation, and air conditioning (HVAC) system is one of the most important parts of your home. However, even the best HVAC system can only last for so long.

Most modern HVAC systems are made to last, especially for newer homes. But unfortunately, when an HVAC system reaches the end of its lifespan, you may have no other choice but to replace it.

Here are the signs it’s time to replace your HVAC system:

1. Your system is too old

Calling for residential or commercial HVAC repair service in Utah or any other state to maintain your system can help maximize its lifespan. However, an HVAC system can only last for so long.

The Department of Energy recommends replacing HVAC systems every 10 to 15 years in order to maintain efficiency and comfort. That said, if any part of your HVAC system is already more than 10 or 15 years old, it might be time to replace it.

2. Increased repairs

If you find yourself having to call in a repair service to fix your HVAC system, then you might be better off just replacing it entirely. Although a whole new HVAC system does not come cheap, it will be much better making the investment than spending endlessly on repairs.

3. Discomfort

Does your house have uneven heating or cooling? Or does your air quality suffer because of the HVAC system? If these problems arise and refuse to go away no matter what you do, you might be better off replacing your HVAC system.


4. Loud and unusual noises

It’s normal for the system to create relatively quiet sounds like humming or groaning. However, when the sounds start becoming louder or more bizarre (e.g. screeching, grinding, squealing, banging), there might be a problem with your HVAC system or its parts.

Call a professional to find the source of the sounds and see if they can stop the noise. If the strange noises persist after repairs, a replacement is likely in order.

5. Strange odors

Strange smells coming from your HVAC system can be caused by a multitude of reasons, such as melting wiring, mold growth, or pest infestation. Here are common odors that come from HVAC systems and what they might mean:

  • Musty smell – mold growth
  • Burning smell – melting wiring, overheating, electrical or mechanical issues
  • Pungent smell – clogs, accumulated dirt
  • Sulfuric smell – gas leaks

When you smell a strange odor coming from your vents, contact a professional immediately. If you smell gas, get out of the house after you call for help.

6. Respiratory problems

Having an old or poorly-maintained HVAC system can lead to poor indoor air quality, which, in turn, causes respiratory problems for the house’s occupants. Don’t wait for a family member’s asthma to get worse or your allergies to strike; have your HVAC system checked and replace it if needed.

Most homeowners don’t want to replace their HVAC system because it’s can be costly. However, if you have a faulty system, you might be spending more on increased utility bills and repairs in the long run. If you see these signs in your house, call an HVAC maintenance company to see what your best options are.
