New Jersey’s recent record-breaking heatwaves highlight the need for an air conditioning system you can rely on to keep you comfortable and cool. Sometimes, your AC may just need a simple repair, but some problems can be signs that you need a new air conditioner.
Sam’s Air Control Heating and Cooling provides comprehensive AC maintenance, repair, and installation to help you get the most out of your home comfort system. Look for these common signs that your HVAC needs to be replaced to know when to call our team for professional installation and energy-efficient upgrades.
Replacing an air conditioner can reduce energy and repair costs and boost long-term savings. Common signs your air conditioner needs replacement include the following:
1. Your AC is more than 10–15 years old
The average lifespan of an air conditioner is 10 to 15 years. If your AC is more than 10 to 15 years old, it’s probably due for replacement. Even with proper maintenance, air conditioning systems experience gradual wear and tear as they approach the end of their average lifespans, and components eventually deteriorate.
2. You’re paying for frequent repairs
Air conditioners require routine maintenance and prompt repairs when problems occur. If you’re paying for frequent repairs, your costs may have diminishing returns, and it’s one of the biggest and most urgent signs you need a new AC unit. Paying for repairs repeatedly will eventually rival the cost of upgrading to a new unit.
Weigh the costs of frequent repairs against a new air conditioner to determine which is most practical. Sam’s Air Control has flexible financing options available to make paying for a new system easy, affordable, and convenient.
3. Your energy bills keep climbing
If your energy bills keep climbing without a change in AC usage, it could be time to upgrade. Rising energy bills cost you more money each month, and they often indicate reduced AC efficiency.
A reduction in energy efficiency affects both your wallet and the environment. Upgrading to an energy-efficient system with a higher SEER rating can reduce your carbon footprint and is an environmentally sustainable choice. Contact Sam’s for a professional AC inspection and diagnosis to determine the cause behind your climbing energy bills.
4. Your AC no longer cools your home effectively
If your AC no longer cools your home effectively, whether producing warm air or cooling unevenly, it could be due to something as simple as a dirty air filter. However, air conditioners that can’t keep up with cooling needs may have more serious problems.
Poor cooling performance may occur due to a refrigerant leak or low refrigerant charge, a malfunctioning compressor, frozen evaporator coil, damaged blower motor, or other problems that are more complex and costly to fix. After getting a professional AC diagnosis, consider whether it’s best to install a new AC rather than pay for repairs.
5. Your AC uses R-22 refrigerant (now phased out)
Many older air conditioners use R-22 refrigerant. In 2020, the Environmental Protection Agency (EPA) officially phased out the production and import of R-22 as part of the transition to more efficient refrigerants with significantly lower environmental impacts.
As domestic components and supplies for R-22 air conditioning units deplete, it’ll become more difficult and prohibitively expensive to source parts needed for continued repairs or recharging. While it’s possible to convert an AC that uses R-22, it’s impractical in most cases, and replacements are more cost-effective and beneficial overall.
Systems installed or manufactured prior to 2010 may use R-22. To verify if your air conditioner uses R-22, check the user manual, inspect the nameplate on the outdoor unit, or call Sam’s Air Control for help.
Signs Your Whole HVAC System Needs to Be Replaced
In addition to your AC, look for other signs that your whole HVAC system needs to be replaced, including heating equipment, ductwork, and thermostats:
- Incorrect sizing: Many homes have outdated or undersized HVAC systems that can’t evenly regulate temperature and humidity. Multi-story homes with undersized air conditioning and heating systems often find upstairs levels too warm in the summer and too cold in the winter.
- System compatibility: Mismatching HVAC components can compromise efficiency and longevity. Some homes have old or retrofitted ductwork that can’t properly balance airflow.
- High energy bills: Efficiency declines as your HVAC system nears the end of its lifespan, increasing your energy bills throughout the year. Replacing your HVAC with a modern system featuring variable-speed technology, optimized ductwork, and other energy-efficient upgrades can provide significant year-round savings.
Why You Shouldn’t Delay AC Replacement
Consider these reasons that you shouldn’t delay AC replacement when it’s approaching the end of its operating life.
Repair cost savings
The longer you wait to get an AC replacement, the more likely your current system will break down. Constant malfunctions result in frequent repair costs that quickly add up. Upgrading your air conditioner may be a higher upfront investment, but you’ll save in the long term by avoiding breakdowns.
Peace of mind
As the summer temperatures climb, you rely on your air conditioner more to keep you comfortable and cool. An air conditioner upgrade provides peace of mind in knowing you can rely on it for consistent cooling. Upgrading your system early, before the summer begins, is the best way to make sure your home is cool when temperatures start to rise.
Warranty coverage
Manufacturer warranty periods vary, but they leave you responsible for repair costs when they eventually expire. With a new air conditioner, you’ll also have new warranty coverage that usually covers breakdowns related to manufacturer defects. A new system gives you reliable cooling and protection for your wallet if something goes wrong.
Parts availability
The home comfort industry continually changes products and updates key components. If you have an older system, it might become more difficult for your HVAC company to obtain the parts required for repairs. New air conditioners are easier to repair, since their parts are more likely to be widely available.
Reduced environmental impact
Compared to modern systems, older air conditioners require a lot of energy and can have a significant impact on the environment. The sooner you upgrade to a heat pump or central air conditioner with high SEER2 ratings, the sooner you’ll help reduce emissions.
