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 leaving you with the comfort you desire, you may need to consider air conditioner replacement. Take a few seconds and think about this scenario: it’s only a few weeks in to the summer and you’re enjoying a stress-free day at home. As lunchtime nears, you realize that it’s starting to feel awfully warm inside. You check the thermostat and all appears to be well with the settings, but the temperature is reading 85 degrees. It’s quite possible that you rode it out as much as you could, but now it’s time to call in an expert and find out 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 Florissant, you don’t want to be stuck without what could be the single most important piece of home comfort equipment you own. Here are a few things you should be watching for if you think your air conditioner has stopped working: Insufficient air flow. If you recognize 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 view your air conditioner’s outdoor fan and it doesn’t run, you’ll want to give the experts at B & B Heating & Cooling in Florissant a call. That fan is responsible for the transferring of heat from your home to the outdoors. If it doesn’t run, that heat transfer isn’t occurring and can cause various issues, including overheating of the compressor and other potential internal problems. Outside obstructions. If your air conditioner is currently surrounded by shrubbery or other potential obstructions, there could be a concern with good air flow to the unit. Over time this could also mean that dirt and debris end up clogging your system and damaging its cooling abilities. Make certain your system is free from obstructions and is cleaned regularly to potentially reduce your chances of needing air conditioner replacement. Dirty filters. One of the most common problems that B & B Heating & Cooling sees is improperly cared for filters. Dirty filters not only reduce airflow, they can also impact your system’s efficiency and can drive up your 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 moving 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 B & B Heating & Cooling at 314-325-7552. Having a broken air conditioner and dealing with air conditioner replacement doesn’t have to be a headache.
