Is It Time to Replace Your Air Conditioner?
With time and regular use, even the most well-maintained air conditioners will eventually reach a point where replacement is a more viable option than repair. One key indicator that it may be time to replace your air conditioner is its age. Generally, air conditioning units have a life expectancy of 10 to 15 years and even up to 25 years with lighter use and proper maintenance. However, if your system is approaching or exceeding this range, it becomes increasingly likely that you'll experience frequent breakdowns and reduced energy efficiency.
Some signs that you may need to replace your air conditioner include:
- Frequent breakdowns (especially for the same problem)
- Your unit needs an extremely expensive repair
- Rising energy bills
- Inconsistent temperatures throughout your home
- Excessive noise while running
Additionally, older systems often use outdated refrigerants like R-22, which is being phased out due to environmental regulations and can be costly to replace or recharge. R-22 can harm the environment, so modern systems utilize new, energy-efficient refrigerants that are better at transferring heat and not as harmful to the planet.
Enjoy Efficient Cooling with AC Maintenance!
Regular air conditioning maintenance can help protect your cooling system from costly breakdowns and even help you save money on your energy bills! For this reason, we strongly recommend having your air conditioner maintained at least once a year. The best time to schedule an air conditioning maintenance service is during the spring, before the onset of the hot summer months, but you can and should schedule at any time, particularly if it has been some time since you last had your air conditioner professionally serviced.
During a maintenance visit, a trained technician will perform a comprehensive inspection and cleaning of your unit. This typically includes checking and cleaning filters, inspecting electrical connections, measuring refrigerant and pressure levels, and examining components for wear and tear. Additionally, the technician will lubricate moving parts, test the system's functionality, and identify any potential issues before they escalate into significant problems. This proactive approach helps maintain optimal performance, reduces the likelihood of unexpected breakdowns, and can ultimately save you money on costly repairs. Likewise, by addressing any minor issues beforehand, you can avoid the inconvenience of a malfunctioning unit during a heatwave.
Make your comfort a priority by scheduling an annual check-up for your air conditioning system well in advance of the summer season. Schedule yours by contacting Dunn Heating and Air Conditioning today with our online contact form.
