A few days of warm weather is a welcome relief after a cold Michigan winter.  It’s a time to open the windows, and let the outdoors, indoors.  That works until rising temperature and humidity motivate turning on the AC.  Mechanical Extremes knows exactly when that happens.  That’s when the team hears from people who are clearly dissatisfied with the results.  The AC runs, but out comes moist, warm air — or only moderately cool air.

What could be the problem?

As with any complex electro-mechanical device, more than one culprit could be the cause.  Here’s one.  Less than adequate refrigerant will certainly degrade performance.  That points to a leak, and a dilemma.  Refrigerant can be added, but is only a temporary cure.  If the leak is not repaired, then the problem will reoccur.

Bottom line?  Mechanical Extremes’ Harold Wilkes says “no system should leak and ever require topping off the refrigerant – it’s not like oil or anti-freeze in your car.”

Mechanical Extremes carefully diagnoses situations where leakage is suspected.  Refreshing the fittings could be an answer, and may be the proper solution.  But it can be different for older systems.  Because of EPA regulations, replacing refrigerant in older systems is increasingly costly.  And other deficiencies could mean investing in repairs may not pay off.  That’s when replacing the system could put you ahead.  If so, is there an upside?  Two major pluses: the efficiency of a new system will deliver improved performance and can be a relief to your utility bill.
