When To Replace Your Air Conditioner
One of the hardest parts of this decision is knowing when it is truly time to stop repairing an older unit. Many homeowners contact us after dealing with several breakdowns in a short time or noticing that some rooms never feel as cool as they used to. They want an informed opinion about whether replacement is the smarter long-term choice.
- Age is often a major factor. If your central air system is approaching 15 years or more, it may be less efficient than current models, especially in our humid summers. Frequent repairs, rising energy bills, or loud operation can signal that the system is working harder than it should just to keep your home livable.
