When is it Time to Replace Your AC Unit? A Comprehensive Guide from an HVAC Expert

As an expert in the field of heating, ventilation, and air conditioning, I am often asked about the lifespan of AC units and when it's time to replace them. The average lifespan of an air conditioning system is 10 to 15 years, but there are several factors that can affect this timeline. If your unit is approaching the 10-year mark, it's important to start considering a replacement rather than investing in costly repairs. Even if your AC unit appears to be working, it may be costing you more money than necessary. As units age, they become less efficient, resulting in higher energy bills.

So how can you determine if it's time to replace your AC unit or if you can squeeze a few more years out of it? Here are some questions to ask yourself:

• Is my unit more than 10 years old?
• Is my home not as energy efficient or comfortable as I'd like it to be?
• Have I noticed any strange noises or issues with my AC unit?

If you answered yes to any of these questions, it's time to have an HVAC professional inspect your unit. While some issues may be fixable with repairs, most of the time, strange noises are a sign of larger problems that require a full replacement. When it comes to choosing a new AC unit, it's important to work with a reputable company that installs systems from trusted manufacturers. At King, we exclusively install units from Carrier, a company that has spent years perfecting their products for long-lasting reliability. Another factor to consider when replacing your AC unit is the type of coolant used. Older models may still use R-22 coolant, which has become increasingly expensive.

In contrast, newer units use the more affordable and environmentally friendly R410-A coolant. Let's take a look at an example to see the difference in cost over 15 years:

• Older unit with R-22 coolant: $1000 for initial installation + $500 for annual maintenance = $8500 over 15 years
• Newer unit with R410-A coolant: $2000 for initial installation + $200 for annual maintenance = $5000 over 15 years

As you can see, investing in a newer unit can save you a significant amount of money in the long run. It's also important to note that regular maintenance is crucial for extending the lifespan of your AC unit. This includes changing filters, cleaning coils, and having annual inspections by a professional. Not only will this help your unit last longer, but it will also ensure that it runs efficiently and saves you money on energy bills. When it comes to replacing your AC unit, it's best to leave it to the experts.

By working with a reputable company and keeping up with regular maintenance, you can ensure that your new AC unit will last for many years to come.
