Expert Air Conditioner Replacement​

Every heating and air system has a finite lifetime. Even with diligent maintenance, after 12+ years, your system just won’t perform like it used to. If your current system has had multiple parts replaced over its lifetime, and has just broken down, it might be time to consider calling in the pros for an AC system replacement.

Save Money With a New HVAC System

Save on Air Conditioning in North Augusta, Columbia & Beyond!

One of the most significant reasons new air conditioners help save money is through increased energy efficiency.

If your system has reached an advanced age, it’s possible that it has a SEER as low as 9. SEER measures the energy efficiency of a heating and air unit. Today, the lowest SEER systems sold in Georgia are SEER 14. This means that even with the most affordable system on the market, you’ll save significant amounts of money on your energy bill every month.

The other reason a complete replacement might be the right choice is when the cost of repairs has become too high. Just like an old car, at a certain point, the cost of replacement parts is higher than the value of the whole system. As a general rule of thumb, if a replacement costs 50% or more of the value of the entire unit, you should consider replacing it instead.

Not Sure if It’s Time for a Replacement? Give us a Call!

If you are experiencing issues with the performance, safety, or reliability of your air conditioner and are facing yet another repair, you may need to decide whether to repair or replace your AC. Our highly qualified, certified technicians can help you determine the best course of action, with a free, no-obligation evaluation of your current system. Signs you may need to consider an air conditioning replacement include:

Lack of Comfort

If your AC is no longer able to maintain the desired temperature in your home or control humidity, you may need an AC replacement. Once your system approaches the end of its life, it may struggle to keep your home cool and comfortable as components begin to fail due to age and use. 

Increased Energy Costs 

An unexplained rise in the cost of energy is a sign your AC may be working harder than necessary to cool your home and may need to be replaced. 

Weak or No Airflow

A lack of sufficient airflow may signal an issue with your ductwork, or you may be overdue for a filter change. It may also be a sign that your AC is no longer functioning as it should or is incorrectly sized, and may need to be replaced. 

Old Age

With an average lifespan of 15 to 18 years, you should consider thinking about a replacement somewhere around the 12-year mark. 

Frequent or Costly Repairs

If you find yourself calling for air conditioner repair once or more each season, or you are facing a repair that is more than 50% of the cost of replacement, it may be more cost-effective to purchase a new unit. 

Strange Odors or Sounds

Odd noises such as grinding, squeaking, or banging are signs that something is amiss with your AC, while a musty odor may mean you have mold in your ductwork or on system components. 


Water or coolant leaks are cause for concern and may cause damage to your home or the environment. 


Frequent on-and-off cycling is a sign that your AC is improperly sized for your home and may need to be replaced, or that your refrigerant levels are low due to an improper charge or leakage.

Air Conditioning Installation Services FAQ

If you need a new or replacement HVAC unit, Sig Cox’s professionals will recommend the best makes and models to suit your specific needs. We have years of experience in installing any HVAC system in a safe and timely manner.

If you explore around, you’ll find dozens of different AC equipment brands, each offering the same promise of quality heating and cooling. With the sheer amount of products on the market, it’s difficult to make a decision. To help you navigate the world of heating and air, we’ve compiled some of the most Frequently Asked Questions about HVAC equipment.

Q: How Much Does it cost to install a new Air Conditioning Unit?

A: Installation of a central air conditioning unit varies with the brand and fluctuates some with the market, though most equipment and their installations cost between $3,000 to $7,000.

What are the Types of Air Conditioning Units I Can Install?

A: Homeowners have many options for air conditioning equipment. The most common type of equipment is a central air system, but some homes require other types of HVAC equipment like ductless mini-split systems or window units.

Are There Any DIY Installation Guides?

A: We do not recommend you attempt to install an HVAC unit yourself. To conduct an installation safely, special tools, training and education are necessary. A professional installer will guarantee the quality of the job. If you’re not careful, you can damage the equipment and injure yourself.

How Long Does an AC Installation Take?

A: A standard installation can usually take between 4 to 10 hours. The complete air conditioner and furnace system installation project ranges from 8 to 14 hours. We aim to complete entire installations in one day.

When Do I need to Install a New Air Conditioning System?

A: You should have maintenance inspections scheduled, from which your service provider may recommend a replacement. If you notice any strange noises, smells, or the unit simply doesn’t heat or cool as efficiently as it used to, these may be red flags that you need a replacement unit. If your system is over 12 years old, it’s usually time to think about a replacement.
