In fact, so much has changed in A/C technology in recent years, almost any significant breakdown warrants replacement. - **You’re paying for frequent repairs.** This is a sign your system isn't running efficiently. Not only is it costing you money in inconvenient repairs, but also added money in energy dollars. If frequent breakdowns are common or your repair bill will add up to half the cost of a new system, it's time to replace the A/C. - **The system is noisy.** Noise is typically a sign of a system that's wearing out and struggling to keep up with cooling demands. - **You have uncomfortable warm and cold spots throughout the home.**  Equipment problems and poorly sealed ductwork can result in uneven cooling throughout your home. - **You frequently suffer humidity problems.** Poorly operating or inadequately sized equipment can cause your home to be too [humid](https://bc.rodenhiser.com/rodenhiser-blog/whole-house-dehumidifier.html) in the summer and too dry in the winter, leading to air quality issues. ## Other Factors Signaling A/C Replacement - **New refrigerant and the phase-out of old -** New, EPA-approved R-410A refrigerant is being used in all new systems built since 2010. This makes the cost of R-22 necessary to repair your old system much more expensive due to its [phaseout](https://bc.rodenhiser.com/rodenhiser-blog/r-22-refrigerant-phaseout-facts.html) by 2020. - **Increased SEER -** Since 2006, seasonal energy efficiency ratio (SEER) has been raised from a standard of 10 SEER to a minimum standard of 13 SEER, translating to a 30 percent reduction in electrical consumption and energy costs. Boost the SEER ratings and the savings are even greater. Are signs showing it’s time to replace the A/C?
