Spring is on the way, and with it comes that familiar Michigan tease–cool mornings, warm afternoons, and the promise that real heat isn’t far behind. When it flips from pleasant to sweltering, will your cooling system be ready?
Mechanical Extremes gets the call when it’s not. The air conditioner runs, but the house still feels humid. The airflow is lukewarm instead of crisp and cool. Or worse, the system won’t start at all.
Because HVAC systems are complex, there can be several causes. One common issue? Low refrigerant. When levels drop, performance drops with it. But refrigerant doesn’t just “get used up.” If it’s low, there’s a leak, and that creates a decision. Adding refrigerant may restore cooling for the moment, but it’s only a temporary fix. Without repairing the leak, the problem will return.
As Mechanical Extremes’ founder Harold Wilkes explains, “No system should leak and ever require topping off the refrigerant—it’s not like oil or antifreeze in your car.”
That’s why Mechanical Extremes takes a careful diagnostic approach when leakage is suspected. Sometimes the solution is as straightforward as tightening or refreshing fittings. In other cases, particularly with older equipment, EPA regulations have made certain refrigerants expensive and harder to source. Add in age-related wear or declining efficiency, and investing in repeated repairs may not make financial sense.
When replacement becomes the smarter move, there’s good news. Today’s systems are significantly more efficient, delivering stronger performance, better humidity control, and meaningful relief on monthly utility bills.
