DIY Air Conditioning Service Maintenance
If you central air conditioner system ceases working during some sort of brutal summer warmth wave, you could be waiting days, or even weeks, for an visit with a maintenance technician to correct it, and it also? t probably going to cost a few hundred dollars. Even so, if you? re comfortable working close to electricity and ready to spend below $100 on parts, you can probably repair your air conditioner yourself on about two hours.
We talked in order to local HVAC repair technicians to get their own best do-it-yourself AC fan repair plus maintenance tips. These tips will support you with the most frequent? low cooling? and even? no cooling? difficulties.
You? ll need a few basic tools: multimeter, some sort of voltage detector, selection of insulated screwdrivers along with a socket set.
If these AC maintenance don? t job, at least an individual? ve covered the particular most common problems, and your services guy can concentrate on seeking the more elusive problem. Additionally, with the fresh parts, you? lmost all likely add years of breakdown-free air conditioning. Here? s how to start.

Set your thermostat to AIR CONDITIONING mode and reduced the temperature setting. If the furnace fan kicks in, the problem isn? t in the particular furnace. If the fan doesn? t work, try resetting the particular furnace circuit breaker. If the lover still won? big t start, call a pro? the fixes displayed here won? big t work.
Next, examine the outside condensing product. The compressor (which sounds like some sort of refrigerator) and lover should be running. When not, stick to the servicing and repair treatments shown here.
Extreme caution: Turn Off the ability
Turn off typically the A/C and furnace breakers in the particular main electrical screen before pulling the particular outdoor disconnect or perhaps removing the distilling unit? s access panel. Then work with a voltage tester within the wires coming straight into the contactor to be able to make sure the ability is really off.
AIR CONDITIONING Doesn? t Work? Buy Parts
The AC contactor (relay) and start/run capacitor(s) (see illustration below) fail most usually and are also inexpensive. As a result it? s some sort of safe bet to buy and install these parts right aside, particularly if your weather conditioning service product is older than five years. The condenser fan motor can also fail, but it really runs about $150? hold off purchasing that unless an individual? re sure? s i9000 the culprit.
To buy replacement parts, get the nameplate upon the condensing product (not your furnace). Jot down the particular make, model in addition to serial number (or take a photo). Get the parts from an appliance store, furnace dealer or even online.
