Bottini Fuel Gives Reasons Your Air Conditioner Might Not Work


When your central air conditioning fails during a heat spell, you may have to wait a few days for an HVAC repair technician or an air conditioner contractor to arrive, and you’ll possibly pay at least several hundred dollars for the repair. On the other hand, if you’re relaxed working around electricity and are prepared to spend about 50 bucks on parts, you can possibly repair your air conditioning by yourself in around two hours and save more than $200 on parts that are marked-up and labor. Bottini Fuel has talked to local HVAC repair specialists to get their best do-it-yourself air conditioner fan repair and upkeep tips. These tips will likely help you with the most common “low cooling” and “no cooling” glitches. All You will need in the way of equipment is an inexpensive multimeter, a voltage sniffer, an assortment of screwdrivers, and a socket set. If these repairs don’t work, at least you have covered the most common issues, and your service guy can focus on locating the elusive problems. Additionally, with the new parts, you’ll likely add more years of breakdown-free air conditioning.


To start, you are going to want to check the following things first.

  1. Furnace – Make sure the problem isn’t the furnace, as this is the number one reason. Adjust your thermostat to AC mode and reduce the temperature setting. If the furnace fan starts up, the problem is not in the furnace. If the fan does not run, try resetting the furnace circuit’s breaker in the unit itself, not at the fuse box. If the fan still fails to start, call in the professionals — there is nothing you can do beyond that.
  2. Fuses – If you are still with us, the next step you are going to take is checking the fuses. Start off by setting your multimeter to the lowest Ohms scale and touch the red and black leads to opposite ends of each fuse your unit has. If you get a numerical reading, the fuse is good, and you can move on. If, however, a zero, a minus symbol or an infinity symbol (∞) is on the read-out, the fuse is blown, and you need to replace it.
  3. Capacitor – A capacitor is the part of the unit that stores and dispenses energy. If this is not functioning properly, you are going to need to replace it. Simply test the unit in the same fashion that you tested the fuses. The read-out values described in step two will be the same for each result. If you get that bad result, you are going to need to replace the unit. As a side note, you need to be extra careful with capacitors, as they do store electricity and there is a mild risk of shock.


If all the things above have failed to produce the desired results, it is time to seek a professional. Bottini Fuel hopes that you have enjoyed this article and have found it to be useful. On a final note, make sure you have electricity to the unit closed at all times.
