We talked to neighborhood HVAC restore technicians to get
their excellent do-it-yourself AC fan to restore and maintenance suggestions.
These recommendations will help you with the maximum commonplace “low cooling”
and “no cooling” troubles. You’ll want an inexpensive multimeter, a voltage
sniffer, an assortment of insulated screwdrivers, and a socket set.
If that AC Repair doesn’t work, at a minimum you’ve blanketed the maximum
common disasters, and your provider man can focus on finding the more elusive
problem. Plus, with the new elements, you’ll probably upload years of
breakdown-unfastened air conditioning. Here’s the way to begin.
Why Is My Air Conditioner Not Cooling the House?
Make Sure the Problem Isn’t the Furnace
Set your thermostat to AC mode and lower the temperature
setting. If the furnace fan kicks in, the trouble isn’t within the furnace. If
the fan doesn’t run, attempt resetting the furnace circuit breaker. If the fan
nevertheless won’t begin, call a seasoned — the fixes proved right here
gained’t work.
Next, test the outside condensing unit. The compressor
(which feels like a refrigerator) and fan ought to be strolling. If not, follow
the troubleshooting and restore techniques proven here.
Caution: Turn Off the Power
Turn off the A/C and furnace breakers within the important
electric panel earlier than pulling the outside disconnect or putting off the
condensing unit’s get entry to the panel. Then use a voltage tester on the
wires entering the contactor to ensure the strength is surely off.
AC Doesn’t Work? Buy Parts
The AC contactor (relay) and begin/run capacitor(s) (see
illustration below) fail most customarily and are less expensive. So it’s a
secure bet to shop for and deploy those components proper away, in particular,
if your air conditioning service unit is older than 5 years. The condenser fan
motor also can fail, but it runs about $one hundred fifty — preserve off buying
that until you’re certain that’s the culprit.
To buy substitute components, find the nameplate on the
condensing unit (no longer your furnace). Jot down the make, model and serial
number (or take a photo). Get the parts at an equipment keep, furnace provider,
or online.
