Air Conditioning Repair FAQs

Maintenance Questions

  • How long will my air conditioner last?

    • Good air conditioners can last as long as 15 years with regular maintenance; however, if neglected they can start having problems after seven years. For new units, check your filters monthly and replace them when needed. Keep the outdoor unit free of debris and if possible, shade the unit during the hottest parts for the day. By using proactive care, it is possible to extend the life of the air conditioner and keep it working in perfect condition.

  • What’s the best temperature to set my thermostat?

    • The best temperature to set a thermostat depends on what is comfortable for your family. For most, that would be between 75 and 80 degrees Fahrenheit and others it will be much lower. When summer starts try a higher setting and then lower to a more comfortable temperature.

  • How do I maximize my air conditioner’s energy efficiency

    • There are several ways to increase an air conditioner’s energy efficiency including: leaving all air vents unblocked, installing a programmable thermostat, performing preventative maintenance and using ceiling fans to help keep rooms feeling cooler, so you can turn the thermostat up.

Repair Questions

  • What are some signs my air conditioner isn’t working right?

    • Air conditioner units that suddenly make new noises or if new odors are present at any setting, then the unit should be checked out right away. Other issues include if air conditioning unit running constantly despite temperatures under 100 degrees Fahrenheit or blowing warm air. And utility bills that increase dramatically despite normal usage.

  • When should I have my air conditioner charged?

    • Air Conditioners are a closed system just like the radiator of a car. Regular chargers are necessary and you only need to charge a system if a leak is present. If a leak is present, hire a professional right away.

  • Why is there water around my indoor air handler?

    • Indoor air handlers do double duty, removing heat and moisture from the air in one go. Designed with a small pan to catch the moisture, but occasionally the drain pan gets plugged from time to time. If you see water around or underneath the indoor air handler, remove the drain line and clean with bleach or vinegar water to clear out build-up.

  • What does it mean if my air conditioner freezes up?

    • Air Conditioners freeze up because of restricted air flow. Turn the unit off soon as you notice a problem and check the filter. If it’s new you may have accidently blocked the air return or have a refrigerant leak. Check your vents before you call a professional.

Replacement Questions

  • How do I know it’s time for a new air conditioner?

    • Once your air conditioner has passed its 7th year, most likely, any major repair is going to be more expensive than replacing the unit all together. An older unit is going to cost you more in maintenance and higher energy cost with each additional year.

  • Can I replace my outdoor unit without replacing the indoor unit?

    • A mismatched unit, a newer outdoor unit and an older indoor unit will end of costing you more money in long run. A hybrid system like this may not even be compatible by using completely different Freon, for example. It is better to replace all parts and units at the same time for maximum effectiveness.  

  • Will a new air conditioner save me money?

    • Definitely, modern units offer more cooling, less electricity while keeping energy costs low.

  • Should I buy a bigger unit than the one I’m replacing?

    • No. Do not be tempted to size up unless your old unit was incorrectly sized to begin with. A too large of unit will operate frequent short cycles, preventing it from removing humidity properly from your home and shortening its lifespan.
