Answers to Some of the Most Frequently Asked Air Conditioning Questions

small_5397530925We’re well into summer, which means Jerry Kelly’s technicians and installers have already visited many, many homes here in the St. Louis area. During our visits, homeowners ask a number of great questions about their air conditioning systems. Some of these questions get asked more often than others, so we thought it would be a good idea to answer some of the most frequently asked air conditioning questions here on our blog!


Answers to frequently asked air conditioning questions


Q: How often do I need to change my filter?


A: This depends on the type of filter that you use. Most filters should be changed every month, but some are designed to last 3 months or longer. Even if your filter is designed to last longer than a month, it’s still a good idea to check on the condition of it single every month.


Q: How often should refrigerant be added to my A/C?


A: Never! This is one of the most common misconceptions about air conditioners. The only times that you’ll need to have refrigerant added to your A/C are when you have a refrigerant leak or when a contractor didn’t add enough refrigerant to begin with.


Q: I already had a furnace tune-up, do I need an A/C tune-up as well?


A: Yes! Although furnaces and air conditioners share some of the same components, they use many of their own components as well. You should schedule two tune-ups per year, one for your furnace and one for your air conditioner.


Q: What size air conditioner do I need?


A: This depends on the specifications of your home. Keep in mind that the “bigger is better” philosophy is not true for air conditioning systems, and a well-qualified contractor will need to take detailed measurements of your home before choosing the right sized air conditioner.


Q: Should I close the air registers in unused rooms?


A: No! Your air conditioner is designed to cool a space of a specific square footage, and your system will experience pressure, performance and efficiency problems if you close off vents in individual rooms.


Q: How should I take care of my air conditioner during summer?


A: The two most important things you should do to take care of your A/C are: 1. Schedule an annual tune-up and 2. Check/change your air filter every month. These two tasks alone will greatly improve the performance and efficiency of your system. It’s also a good idea to keep an eye out on your air conditioner’s outdoor unit and remove any visible debris within a few feet of it.


Q: What temperature should I set my thermostat at?


A: This depends on your family’s particular preferences. For maximum energy-savings, your at-home temperature should be somewhere between 75-78 degrees. If that’s too warm for your family, lower it by one degree at a time until you find a temperature that everyone’s happy with. You can also save energy by raising your thermostat by about 5 degrees when you’re away from home and/or sleeping. A programmable thermostat makes this simple!


Q: How long does an air conditioner last?


A: A well-maintained air conditioner should last somewhere around 15 years. A poorly-maintained air conditioner, however, will probably last a number of years less than that. Take great care of your system to ensure you get the longest possible operating life out of it!
