“What are some of the more com­mon prob­lems that units have in the hot sum­mer weather?”

Northwest Arkansas Democrat-Gazette - - VOICES -

An­swer: Sum­mer­time is al­ways fraught with prob­lems. Three of the most com­mon prob­lems are con­den­sa­tion leaks, in­suf­fi­cient re­frig­er­ant and faulty ca­pac­i­tors. Con­den­sa­tion leaks are caused by lint and dust that passes through the fil­ter and col­lects in the con­den­sate line. When it clogs up, it spills over and makes a real mess. In­suf­fi­cient re­frig­er­ant is com­mon with the huge push for higher ef­fi­ciency coils. To that end, coils are be­com­ing thin­ner and thin­ner, caus­ing them to leak oc­ca­sion­ally. And now, with R-22 Freon be­ing phased out, this has be­come quite ex­pen­sive.

Oc­ca­sion­ally, you will find a 30-year-old air con­di­tioner still sport­ing its orig­i­nal run ca­pac­i­tor. This is be­cause back then, the units were built with Printed Cir­cuit Board’s (PCB’s) in them and they would al­most never go bad. But now, they go bad more of­ten than they should. I try to stay with Amer­i­can made PCB’s be­cause one sum­mer, I had to re­place ev­ery one that had been pur­chased from out­side the coun­try.

Run ca­pac­i­tors are in­ex­pen­sive, but the dam­age a bad run ca­pac­i­tor can cause to your unit can be­come costly to repair. A bad run ca­pac­i­tor can dam­age your com­pres­sor, blower mo­tor or the fan mo­tor, and these can be very ex­pen­sive to re­place.

The good news is that all three of these prob­lems can be avoided with a sea­sonal checkup. Please call Bella Vista Heat­ing and Air at 479-273-9640 to sched­ule your ap­point­ment and avoid these costly re­pairs!
