Frequently asked questions about air conditioning equipment.
How long will my air conditioner last?
Quality air conditioners can last as long as 15 years if they’re properly maintained. However, average air conditioners are expected to develop problems after seven to ten years if they’re not maintained. If you want to get the most out of your AC system, check your filters monthly and replace them as needed, keep your outdoor unit clean and free of debris, and have your system serviced by a trained HVAC technician at least once a year. By performing maintenance, you can greatly extend the life of your air conditioner and keep it working at its best.
What temperature should I set my thermostat to?
The best temperature for your thermostat is the highest temperature your family is comfortable at. For most people it is between 75 and 80 degrees.
How often should I change my air filters?
Check your air filters monthly. If there is any discoloration or visible layers of dust, you should change your air filter. Air filters need to be changed every 30 days on average and sometimes every two weeks during summer months when your air conditioning is more frequently used.
How do I know if my air conditioning isn't working right?
Air conditioners that suddenly start making new noises or produce new smells should be checked right away. Other signs that your unit is having problems include its running constantly despite temperatures under 100 degrees Fahrenheit, blowing warm air into the room, or utility bills that increase dramatically despite normal usage.
Why is there water around my indoor air handler?
Indoor air handlers do double duty, removing heat and moisture from the air. They are designed with a small pan to catch the moisture, but occasionally the drain line from the pan may become plugged. If you see water around your indoor air handler, remove the drain line and give it a good cleaning by running vinegar water through it to help clear out any build-up.
What does it mean if my air conditioner freezes up?
Usually, an air conditioner that has frozen is suffering from restricted air flow. Turn the unit off as soon as you notice a problem and check the air filter. If the air filter is clean, you may have blocked the air return. If not, you may have a freon leak and need to schedule a service call.
How do I know it's time for a new air conditioner?
Once your air conditioner has passed its seventh year, it’s likely that any major repair is going to be more expensive than replacing the unit. An older unit that’s showing signs of trouble and needs frequent visits from the repairman, that cools poorly, or suddenly creates much higher energy bills than in years past is probably ready to be replaced.
Can I replace my outdoor unit without replacing the indoor unit?
In some cases, you can replace your outdoor unit and leave the indoor unit intact if the components are available to match your existing indoor unit. However, you’re always better off replacing all the parts of your air conditioner at the same time for maximum efficiency and performance.
Will a new air conditioner save me money?
Absolutely! An air conditioner that’s just 10 years old may be as much as 60 percent less efficient than a brand new baseline unit. Today’s energy efficient models cool your home using less electricity thus keeping operating costs low.
Should I buy a bigger unit than the one I am replacing?
No. Bigger isn’t always better. Don’t be tempted to up-size your unit unless your old unit was incorrectly sized to begin with. A oversized unit will run in frequent short cycles, preventing it from removing humidity properly from your home and shortening its lifespan.
