Signs You Need A New HVAC Unit

Signs You Need A New HVAC Unit

Summer is quickly approaching, and if you haven’t already, it’s time to turn on your home’s air conditioning. One of the most valuable appliances in any home is the HVAC unit. While you want to keep it running for as long as possible, it’s critical to know when to upgrade and contact AC Service in Garland, TX, for HVAC services.

We’ll go over some red flags that indicate it’s time to replace your home’s HVAC system.

Your Utility Bills Continue To Rise

While spending more on utilities in the summer is normal to keep your place cool, your bill shouldn’t be considerably higher than it was the previous month. Rising utility bills can indicate that your HVAC system needs to be replaced. The system’s efficiency deteriorates over time due to normal wear and tear. The greatest loss of efficiency is caused by a buildup of dirt and rust on the inside.

You Haven't Replaced It In More Than Ten Years

When was the last time you replaced a unit in your home? If it’s been more than ten years, your unit is probably due for a replacement. Every 10-15 years, your HVAC system must be replaced. HVAC units are built with long-lasting components, but they begin to deteriorate after ten years.

The system’s upkeep and frequency of use will determine when it’s time to replace it, but the 10-15 year window is a good starting point. By this point, replacing it with a new unit will reduce your carbon footprint and your monthly energy costs.

Loud Noises

It is normal for older HVAC systems to become noisier as they age. However, if you notice the following noises, it may be a sign that you require a replacement:

  • The blower is humming more loudly.
  • The outdoor unit is becoming more audible.
  • The furnace is banging and groaning.

Some of these noises can be explained by a loose or broken part. Others could be caused by issues with fans, motors, blowers, and other moving parts. However, if the strange noises persist or worsen after repair, it’s time to replace your system.

Multiple Repairs

Many of the individual components of an HVAC system are repairable or replaceable. However, all HVAC systems will eventually wear out and need to be replaced. When a compressor, motor, or coil fails, replacing it is far more cost-effective than repairing it.

While the initial cost of a completely new system may appear high, the cost of ongoing repairs when one of these components fails is not worth it in the long run. That money would be better spent on a completely new system.


Keep an eye out for any problems as you start up your air conditioning this summer. Finding problems sooner rather than later will save you money and keep you from having to replace your entire system.
