Air Conditioner Replacement: what to do when your air conditioner stops working Posted May 28, 2015 Summer and comfort go well together, but when you’re dealing with an air conditioner that isn’t giving the comfort you want, you may need to think about air conditioner replacement. Take a few moments and think about this scenario: it’s only a few weeks in to the summer and you’re enjoying an easy day at home. As lunchtime nears, you recognize that it’s starting to feel awfully warm inside. You check the thermostat and all seems to be well with the settings, but the temperature is reading 85 degrees. It’s a possibility that you rode it out as much as you could, but now it’s time to call in an expert and discover what’s wrong. So what does that mean for you as a homeowner? Well, there are a number of reasons that you might be facing air conditioner replacement. And considering the weather in Grand Prairie, you don’t want to be caught without what might be the single most important piece of home comfort equipment you own. Here are a few things you should be on the lookout for if you think your air conditioner has stopped working: Insufficient air flow. If you sense a change in air flow, check for a blocked return-air or supply-air grille. Be sure all of these grilles are not blocked by furniture or other items. Non-working outdoor fan. If you go outside to inspect your air conditioner’s outdoor fan and it doesn’t run, you’ll want to give the pros at Mustang Mechanical in Grand Prairie a call. That fan is in charge of the transferring of heat from your home to the outdoors. If it doesn’t run, that heat transfer isn’t happening and can cause a number of issues, including overheating of the compressor and other potential internal damage. Outside obstructions. If your air conditioner is currently bordered by shrubbery or other potential obstructions, there could be a concern with proper air flow to the unit. Over time this could also mean that dirt and debris end up clogging your system and hurting its cooling abilities. Ensure your system is free from obstructions and is cleaned routinely to potentially decrease your chances of needing air conditioner replacement. Dirty filters. One of the most common concerns that Mustang Mechanical sees is improperly cared for filters. Dirty filters not only lessen airflow, they can also hurt your system’s efficiency and can drive up your energy bills. They also affect air quality and when allergy season is in full-swing, a dirty filter can have a large impact on your home comfort. If you have checked all of these and your air conditioner still isn’t running, follow these step-by-step instructions, only going to the next step if the system doesn’t start. Check that the thermostat temperature set-point is set below indoor temperature, and the system switch is in the COOL position. Is the outdoor unit power supply switch "on"? Is the furnace/air handler power supply "on"? Check the house fuse box/breaker box for a blown fuse or tripped circuit breaker. If the system still does not operate, call Mustang Mechanical at 972-445-9504. Having a non-working air conditioner and dealing with air conditioner replacement doesn’t have to be a headache.
