  • Always work with a reputable contractor. The air conditioning contractor that you choose to work with can have a big impact on how long your system lasts. If you work with a low-cost, low-quality contractor for your installation, your system might have operational problems from day one that plague the system for the rest of its life. In addition, a low-quality contractor might rush through maintenance and repair calls or even misdiagnose your system and make unnecessary and expensive repairs. By working with a high-quality and reputable contractor like Aurora’s, you can be sure your system is in good hands throughout its entire operating life, including during its installation, annual tune-ups and repairs.

  • Schedule a tune-up every year. Speaking of tune-ups, it’s essential that you schedule a tune-up for your air conditioner every year if you want your system to last as long as possible. Air conditioners are like cars in the sense that they work better and last longer if they are well-maintained. In the same way that you need to periodically change the oil, rotate the tires and add fluids to your car, your air conditioner requires maintenance tasks that should be taken care of during professional tune-ups every year. In fact, many air conditioner manufacturers will void the warranty on your system if you neglect to schedule annual maintenance.

  • Change your air filter regularly. The single most important maintenance task that you are responsible for when it comes to your air conditioner is to change the air filter. Dirty filters are responsible for many of the most common short- and long-term problems that develop with air conditioners, which is why keeping a clean filter installed is one of the best ways to make your air conditioner last longer. Many air filters only last for 30 days, while others can last a few months. Either way, we suggest that you at least check on your filter every month and change it when it’s dirty.

  • Use your thermostat wisely. Anything you can do to limit your air conditioner’s workload will lead to less wear and tear and a longer operating life for your system. One of the best ways to do that is to use energy-saving thermostat settings. When you’re at home, use the highest temperature setting that your family is comfortable with. When you leave the house for the day, raise your thermostat by 3-5 degrees to save energy while your home is empty. Over time, settings like these will save you energy and help keep your air conditioner in good shape. To make your life easier, install a programmable thermostat that will change your home’s temperature levels automatically based on your family’s schedule.

  • Ensure your system has good airflow. In order to keep your home cool while exerting a minimum amount of effort, your air conditioner must have good airflow. If something is blocking airflow through your system, or if air is escaping your ducts, your air conditioner will have to work much harder and longer than usual during every cooling cycle. This added effort will add up to a lot of extra wear and tear over time, which will shorten your system’s operating life. In order to help ensure good airflow, keep all of your home’s vents open and clear of obstructions, clear away plants and debris within a few feet of your outside unit, check and/or change your air filter every month and have your ducts inspected for leaks by Aurora’s HVAC technicians.

Have you run your air conditioner yet this year?  Believe it or not, the temps will be heating up and we are going to need to run our AC units.

If your AC has developed any issues over the winter, the best thing you can do is refrain from using it until you’ve had it tuned-up. Instead of waiting just before the summer returns, however, you can get that maintenance check out of the way anytime before summer.

A few reasons to service your AC unit:


Check your air vents. If you can see dust there, just imagine how much could have formed inside the ducts and in the sensitive components of your air conditioner. Turning on your AC for the first time in several months, some of that dust might even come out and leave a bit of an odor.

The U.S. Department of Energy has found that nearly 25 to 40 percent of the energy used by your AC is wasted due to excessive dust in the system. The dust that can build up on the air conditioning coils and other parts of the system can reduce the AC’s cooling potential.

While air filters are put in place to help prevent this problem in the first place, dust manages to find its way inside the system through other entry points. Plus, if the filter gets too dirty for a prolonged period of time, it will be less effective in filtering out dust.

A little maintenance now saves time and money in the long run

There will come a time when you start running your air conditioner consistently. Soon after that, there will come days so hot that you’ll be very thankful to have a fully-operational air conditioner. The worst possible thing that could happen at that time? The AC breaks down and it’s likely to happen during the hottest part of the season, especially if the unit hasn’t received any maintenance since the year prior.

The most common issues that can cause a malfunction include refrigerant leaks, frozen evaporator coil, dirty condenser coil, broken blower motor or fan. Luckily those issues can be prevented with a quick tune-up.  Give us a call at Aurora Plumbing, Heating, and Cooling. We’d be happy to make sure you’re AC unit is ready when the temps start to rise.
