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 ponder 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 relaxing day at home. As lunchtime nears, you notice that it’s beginning to feel awfully warm inside. You check the thermostat and all appears to be well with the settings, but the temperature says 85 degrees. It’s likely that you rode it out as much as you could, but now it’s time to call in a pro and discover what’s wrong. So what does that mean for you as a homeowner? Well, there are a few reasons that you could be facing air conditioner replacement. And considering the weather in Tucson, you don’t want to be caught without what could be the single most significant 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 recognize a change in air flow, check for a blocked return-air or supply-air grille. Be sure all of these grilles are not covered 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 professionals at Ambient Air in Tucson 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 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 surrounded by shrubbery or other potential obstructions, there could be a concern with enough 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. Make sure your system is free from obstructions and is cleaned regularly to potentially lessen your chances of needing air conditioner replacement. Dirty filters. One of the most common issues that Ambient Air sees is improperly cared for filters. Dirty filters not only decrease airflow, they can also effect your system’s efficiency and can drive up your monthly energy costs. They also affect air quality and when allergy season is in full-swing, a dirty filter can have a great 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 Ambient Air at 520-201-3871.
