Should You Replace Your Old Air Conditioner Or Repair It?

Repair or Replace AC?

If your central air conditioner is more than 10 years old, you may be considering whether it's best to keep repairing the unit, or invest in a new AC system. The old saying "if it ain't broken... don't fix it." makes sense for many appliances around the home, but for your home's heating and cooling system, delaying the purchase of a new system can cost you more in the long run both in higher utility bills and potentially expensive repairs.

The EPA recommends that homeowners consider replacing their air conditioner if it's older than 10 years old. This is because new air conditioners are far more efficient that system installed just a decade ago. How much can you expect to save on your energy bill with a new air conditioner? The most efficient systems you could save up to 56% on your cooling bill.

Here are a few reasons to consider replacing your old air conditioner.

1. The air conditioner is not operating reliably and is in need of frequent repairs
2. Your utility bill for cooling your home is rising as the unit has become older and less efficient.
3. It's LOUD! Today's air conditioners operate at variable-speeds to cool your home more quietly in most situations.
4. It's more than 10 years old. Newer, high efficiency AC systems can pay for themselves in just a few years in lower cooling costs.

Air Conditioner Noises
Most new air conditioners built within the last few years are designed to operate very quietly. When you hear an unusual sounds it's often a sign of inadequate maintenance, or a sign that a part has worn out and is about to fail. By being aware of the different types of AC noises you better determine if there's a problems and have a professional fix the small problems before they lead to an unexpected breakdown.

When an air conditioner is operating normally it will make some familiar sounds. These may include hissing and whirring sounds that are normal and are a result of the unit's blower and compressor operating.

The Sounds of a Malfunctioning Air Conditioner

Air conditioners have many parts; there are fans, hoses, belts, compressor motors, coils and other components that work together to move cool air throughout your home. As air conditioner units age, belts often become loose, leading to thumping sounds. A clogged air filter can reduce air flow and can cause the unit to whine loudly as it cycles on and off. Loose hardware on compressor parts can lead to rattling noises.

If you are hearing unusual sounds from you AC or furnace, it's best to have a qualified technician inspect the unit to ensure it's operating safely and reliably.

The Importance of Regular Maintenance

Preventative maintenance is the best way to minimize the likelihood of air conditioner repairs. An AC tune-up includes the following steps that keep your air conditioner operating quietly and reliably:
  • Inspection and lubrication of all moving parts
  • Inspection and replacement of worn belts and hoses
  • Replacement of dirty air filters
  • Ensuring that the unit cycles on and off properly
  • Inspection of electrical connections
  • Inspection of refrigerant levels

5 Furnace Filter Tips

Written by

Keep Your Heating and Cooling System Working Efficiently and Your Air Healthier

5 Furnace Filter Tips

A common question we hear from our customers is, "How often should I change my furnace air filter?" The answer is usually once a month. Check with the filter packaging for details.  There are a few other things to consider as well:

1. Buy filters in bulk and keep them next to the furnace.

Having filters always ready next to the furnace will reduce procrastination and the tendency to wait too long between filter changes. Also, buying filters in bulk is usually less expensive than buying them individually.

2. Use the correct size filter.

An poor-fitting filter lets dirt and debris escape around the filter, contaminate the air in your home and the parts inside the furnace, leading to reduced efficiency of the unit which can shorten the lifespan of the compressor and other components.

3. Install the filter in the right direction.

Most filters have arrows indicating the direction of air flow. Putting a filter in backwards can cause the filter to work less efficently and in some cases may cause the filter to bend, allowing dirty air around the filter.

4. Always turn of the power at the breaker rather than the thermostat when changing the filter.

This will ensure that if you come in contact with any wiring inside or near the filter you won't get shocked.

5. Furnace filters are not designed as air cleaners.

While most furnace filters will keep a lot of dirt and debris out of the air, they are not going to keep the air free of smaller contaminates and allergens. If your home has excessive dust, pet dander, smoke or other pollutants, consider using a separate, high quality home air filtration system. A HEPA rated filter is designed to capture the smallest particles that can easily pass through most common furnace air filters.
