Today’s modern HVAC systems offer more advanced features than ever before. That in itself is a good reason why many homeowners have their HVAC system replaced. With innovations such as eco-friendly refrigerant, programmable thermostats, variable-speed air circulation, and modulating technology, these elaborate devices function at a higher level than older systems.

There are many other reasons why you should replace your HVAC system. The less common ones are:

  1. You have a carbon monoxide leak.
  2. The compressor fails.
  3. Your unit is more than 12 years old.

1. Is There a Carbon Monoxide Gas Leak in Your House?

Because carbon monoxide (CO) is odorless, it is nearly impossible to detect. CO poisoning can occur without your knowledge. Breathing in low levels of carbon monoxide may cause critical heart issues. Physical symptoms such headaches, dizziness, lethargy, nausea, and vomiting indicate a possible CO leak in your home. If you suspect a carbon monoxide leak, open the windows and doors of the house and call a CO leak detection company immediately.

2. Signs Your AC Compressor Is Going Bad

Compressors typically last between 10-15 years before they start giving you problems. If the AC condenser (the outdoor unit) seems to be running but warm air is coming from the vents, the compressor is probably to blame.

Other signs your AC compressor has failed or is about to fail include:

  • The condensing unit vibrates every time it turns on
  • Clicking or rattling noise
  • Puddling around the unit
  • The outside condensing unit keeps tripping the breaker.

3. It’s Getting Old


One of the reasons why people have their HVAC system replaced is age. If your HVAC system requires frequent repairs, maybe it’s time for a new one. Older HVAC systems need repairs often. If it is more than 12 years old, consider replacing it.

Does it cycle on and off repeatedly? Is there too much humidity inside? Do you spend too much on energy bills? These are all indications that you have an old HVAC unit. Call Total Comfort Heating, Air & Plumbing today at (540) 373-9780.
