When your air conditioner isn’t performing its job in keeping your home cool and comfortable, you’ll want to find the source of the problem and work out a solution. There are several root causes to look for, such as undercharged refrigerant, a leak in the coil, or a short-circuit possibly caused by a nearby lightning strike. Also consider simpler maintenance issues, such as changing a dirty air filter and checking for air leaks. Every little detail contributes to the overall performance and should be looked at.
If your AC unit is over 10 years old and you find the repair will be costly, you may want to consider buying a new, more energy-efficient system. Minimum SEER (Seasonal Energy Efficiency Ratio) ratings have risen from 6 to 13 and higher in the past decade, which is a good thing as higher SEER ratings mean better energy efficiency. Increased efficiency equates to less costly electric bills. Consider this: a new AC unit will save you between 20 and 40 percent on energy expenses over the 10-year-old unit you are still debating about repairing.
