Why You Should Replace Your Air Conditioner

While replacing any appliance in your home isn't always a welcome proposition, replacing your air conditioning unit can have many benefits that make the investment worth it. Replacing an air conditioning unit, especially one that is older than 10 years old, will run at a higher efficiency rate, reducing your monthly electric costs, and also eliminating any future repair bills that you would have to budget in if you kept your old unit. Every second that they run smoothly and efficiently saves you money on utility bills and money on costly repairs, providing you with a return on your investment.

In addition to saving you money, an upgraded and efficient air conditioner helps the environment. Air conditioners that were manufactured before 2010 use a refrigerant known as R-22, a chemical that has been found to be contributing to the depletion of the Earth’s ozone layer. A gradual reduction of this harmful chemical has therefore been initiated, and manufacturers have been banned from making any new air conditioner that uses R-22 refrigerant moving forward. That means that if your old air conditioner isn't working properly, you may no longer be able to get any new R-22 refrigerant at an affordable cost, or at all.

When to Replace Your AC Unit

Part of being a homeowner is deciding when you need to maintain, repair, or simply replace an inefficient air conditioning system. While repairs are great for preventing damage and repairing minor faults, replacement might be a good idea if your air conditioner is old, outdated, or operating inefficiently. Often, an air conditioner that needs to be replaced is costing you more money than simply opting for a new one, which is a long-term investment. If you’re not sure if your old air conditioning system needs to be replaced, then contact John Stevenson Plumbing, Heating & Air Conditioning, Inc., and we will be more than happy to discuss it with you.

Be on the lookout for the following signs that AC replacement is imminent:

Frequent Repairs & Increased Energy Bills 
If your air conditioner needs frequent repairs, or your electric bill is skyrocketing, then it might be time to consider getting a new AC unit. In addition to considering the insulation in your home, consider the performance of your HVAC system. Energy bills reflect any changes in your air conditioner and indicate a usually larger problem, like an inefficient air conditioner or heat pump. Further, air conditioners older than 10 years old need to be replaced, as newer air conditioners are more efficient, and can save you up to 20% on your cooling costs, reducing your electric bills.

Lack of Cool Air or Limited Airflow 
Probably the most obvious sign of an air conditioning unit that needs to be replaced is a lack of airflow coming from the unit itself. If it takes a few minutes to begin producing cold air, that is proof that your AC unit is not performing properly. The issue could be from clogged pipes, which restricts airflow, but no matter what the is, you should call John Stevenson Plumbing, Heating & Air Conditioning, Inc. to have the problem assessed and a plan of action created and put into effect.

Strange Noises 
If your AC unit is louder than it used to be, making noises like grinding, squeaking, or chattering, don’t accept it as white noise to help you fall asleep. A noisy air conditioner that draws attention to itself means that your air conditioner is aging. It is true that some air conditioners operate on a certain noise level, but one that is constantly making you ask the question “Did it always make that sound?” should probably be replaced.

Strange Smells 
In addition to producing strange noises, an air conditioner that needs to be replaced will also produce an unusual smell. Air conditioners should put out clean air that has no scent. If there is a bad smell, you could have a couple of different problems on your hands, including:

  • Standing water from an AC that is not draining properly, which can cause a stale "dirty socks" smell
  • Fungal growth in or near your air conditioner or a dirty air filter that needs to be replaced, which can cause a mildewy smell
  • Leaking fluids from the engine (if your AC is gas-powered), which can cause an exhaust fume odor
  • A gas leak (if your AC is gas-powered), which can cause a rotten egg or rotten cabbage smell

Frequently Asked Questions
  • Should I replace or repair my AC unit?
    A:

    Many customers ask if they should repair a broken air conditioning unit versus a full replacement. Often, a well-maintained and newer AC unit will be able to be repaired depending on the issue. If it is a part under warranty, replacement of the part is a simple fix. However, if the AC is more than 10 years old, has not been regularly serviced, or is in need of a major repair, replacement is the best option. Our team will provide all available options for homeowners to consider.

  • What's a Pre-Installation Evaluation? Does My New A/C Need One?
    A:

    In short, yes. A first step is conducting an energy audit to determine the energy load for your home. Calculating the load tells the experts at John Stevenson Plumbing, Heating & Air how much heat your house gains throughout the day & what size air conditioner will work best to keep it cool. This is critical as most A/C installation issues stem from an improperly-sized air conditioning unit.

  • Is Your Home's Ductwork & Design Able to Handle a New A/C System?
    A:

    Often your old, existing ducts can’t handle the airflow of a newly installed air conditioner. Any upgrades to accommodate a new system will likely increase the cost to install an A/C unit, but will ultimately help you avoid costly, high energy bills & hot rooms in the future.

  • What Type of Central A/C Unit Should I Install?
    A:

    Here’s where the load calculation comes into play, as you want to pick the right size A/C unit to install – either too big or too small of an A/C unit can lead to costly repair or replacement down the road. Call the HVAC professionals at John Stevenson Plumbing, Heating & Air, they’ll know which A/C unit is perfect to install in your home at the lowest price.
