Keep It Cool: 5 Undeniable Signs that You Need a New HVAC Unit

You depend on your AC unit to keep things comfortable inside during hot days. As average temperatures keep rising, that function only becomes more important.

That means you must keep a sharp eye on your HVAC unit. While any machine can have the occasional problem, there are some signs that tell you your HVAC unit's days are numbered.

Keep reading for five signs it's time for a new HVAC unit.

1. Poor Air Cooling

One of the most significant signs that you're due for an HVAC unit replacement is poor air cooling. While it might only mean you need a refrigerant top off, it's just as likely that a major component will fail soon. With major component problems, repair costs can often run as much as an entire replacement unit.

2. Noisy Performance

Another main sign that you'll need HVAC replacement services is noisy performance. This doesn't mean the regular noise of the unit, but new or abnormal sounds. A few you should listen for include: 

  • Grinding
  • Banging
  • Rattling
  • Scraping
  • Squealing

All of these noises can indicate a part failure or one approaching failure. At a minimum, you should get a professional out to look at the unit.

3. Numerous Repairs

Most HVAC units will need some level of maintenance or repair over time. When you find yourself calling the repair guys out every few months or every few weeks, read that as a sign that you need a new AC unit.

Constant repairs often mean that the unit will suffer a catastrophic failure in the near future.

4. Rising Utility Costs

One of the less obvious signs of a problem in your HVAC unit is a steady or abrupt rise in your utility bills you can't account for. A steady rise in the bill often means a steady decline in the unit's efficiency. An abrupt rise often means a significant failure in the unit that hasn't caused one of the other signs.

5. Your AC Unit Is Older

A typical AC unit will give around 15-20 years of service barring a major part failure. Once a unit crosses the decade mark, though, you can expect an increasing number of repairs and a persistent loss of efficiency. Basic usage wears the machine down over time.

Buying a new HVAC unit lets you avoid those ongoing repairs and efficiency losses. As an added bonus, newer units often provide vastly improved efficiency over older units.

Deciding on a New HVAC Unit

Deciding that it's time for a new HVAC unit often stems from noticing one of the above signs. Performance decline, rising costs, and simple age can drive the decision.

Simple quality of life concerns can also drive the decision. A major repair can leave you worrying about whether the unit will stay reliable. In those cases, replacing the HVAC unit can improve your well-being and quality of life.
