Should I Fix My existing Air Conditioner or Get a New Air Conditioner?
Equipment Age
Air conditioning systems generally work for about 10–15 years. After 10 years you might consider replacing the unit instead of investing in a costly repair.
Frequent Breakdowns
You should consider air conditioner replacement if yours requires expensive or regular repairs.
More Expensive Utility Bills
Out-of-date AC equipment isn’t as efficient. If you don’t schedule yearly air conditioner maintenance, there’s a chance you’ll have a less efficient system and more expensive energy bills.
Uneven Cooling
An out-of-date AC unit may run more regularly and have trouble cooling your house. New models are designed to start less frequently to help you save more on electricity costs.
3 Benefits of an Updated Air Conditioner
Up-to-date central air conditioning systems offer advantages over older systems, and you can feel confident you’ll have equipment that will run for many years. A new AC unit can offer:
1. Enhanced Energy Savings
Updated AC systems provide superior efficiency ratings compared to older equipment. A new air conditioner could help you save as much as 50% on your cooling bills, according to the U.S. Department of Energy.
You can potentially save even more with an ENERGY STAR® unit with a great SEER or SEER2 rating. This rank tests an AC unit’s cooling performance.2. Quieter Comfort
A modern air conditioner contains cutting-edge technology to assist it in cooling your residence more quietly.
3. Hassle-Free Cooling
The latest air conditioning technology ensures your air conditioner will last longer and provide comfort more efficiently. When you include your modern unit with a service agreement, you’ll never miss your annual AC service appointment again.
