Several problems can cause an AC system to run without cooling properly, including a dirty filter, airflow restriction, failed capacitor or contactor, refrigerant issue, frozen evaporator coil, outdoor fan problem, thermostat issue or compressor failure. A professional diagnosis can determine the actual cause before repairs are recommended.
That depends on the age and condition of the system, repair history, comfort problems and the cost of the needed repair. If a dependable repair makes sense, we’ll explain that option. If the system is aging or requires a major repair, we can also discuss replacement options so you can make an informed decision.
An AC system can freeze because of restricted airflow, a dirty filter or evaporator coil, blower problems, refrigerant issues or other operating conditions. Continuing to run a frozen system can lead to additional problems, so turn the cooling off and have the cause diagnosed.
Refrigerant leaks can develop from vibration, corrosion, damaged tubing, leaking coils, fittings or other components in the sealed refrigeration system. Refrigerant is not normally “used up,” so a low charge may indicate a leak that should be located and evaluated rather than simply adding refrigerant.
We recommend having the cooling system professionally inspected and maintained at least once each year, ideally before the cooling season. Heat-pump systems benefit from seasonal maintenance because the same equipment operates during both heating and cooling seasons.
Many residential air conditioning systems operate for roughly 12–15 years or longer, but actual service life depends on installation quality, maintenance, operating conditions, usage and the environment. As equipment ages, repair history and overall condition become important when deciding whether continued repairs or replacement makes more sense.
Whether your AC isn’t cooling, needs maintenance, or you’re considering a system replacement, L & J Cooling and Heating is ready to help.
