How to Extend Your Air Conditioner’s Life and Improve Efficiency with Annual Maintenance

Air Conditioning Installation Some of the smartest advice about air conditioner maintenance comes from the renowned 18th century HVAC philosopher Benjamin Franklin: “An ounce of prevention is worth a pound of cure.”
Poorly maintained systems tend to break down when you need them most — when the weather outside is scorching. However, annual air conditioner maintenance can help reduce future breakdowns by as much as 95%, extend system life by up to 50% and lower your utility bill by up to 30%. Plus, most manufacturers require annual maintenance to stay current under your warranty. Our comprehensive air conditioner tune-ups are designed to save you money and unexpected summertime headaches.

Top Reasons to Get Annual AC Maintenance

Save money
Failure to treat your air conditioning system to recommended routine maintenance greatly increases the risk of unexpected problems that can be a real pain in your wallet. Plus, signing up for a preventive maintenance plan can give you access to significant cash-saving discounts and incentives that can include priority response, lifetime workmanship guarantees and waiving of after-hours and emergency fees.

Improve comfort and safety
Having your air conditioning break down in the middle of summer is not only uncomfortable it could be unhealthy, especially for those at risk of exposure to extreme heat. Air quality is also a consideration; regular tune-ups help eliminate dust and debris, mold and germs, while protecting family members who suffer from allergy or respiratory issues.

Extend the life of your system
Regular annual maintenance will make your air conditioner last years longer, saving you the costs of replacement and installation by extending the life of your system. Also, manufacturers require documentation of regular maintenance in order to honor your warranty.

Frequently Asked Questions

Q: What is the most important maintenance task can I do on my own?
A: Change the filter regularly. This helps your cooling system operate at peak levels while improving indoor air quality. The U.S. Department of Energy reports that changing your HVAC filter can lower your air conditioner’s energy consumption by 5% to 15%. High-quality 4-inch-thick filters should be changed every 6-9 months, while cheaper 1-inch filters may need to be replaced every 30 days.

Q: Do I need to have my AC system serviced every year?
A: Yes. Annual air conditioner maintenance is important for the health of your system and the comfort of your family, and necessary to stay protected under the terms of your warranty.

Q: What are some of the issues AC maintenance will detect or prevent?
A: Having air conditioning maintenance performed annually will help uncover potential problems and prevent performance issues, including: low refrigerant levels, refrigerant leaks, frozen coils, broken thermostats, faulty wiring issues, defective sensors, system rupture or explosion, electrical shorts, even rodent or snake infestation.

Q: How important is my indoor air quality?
A: Incredibly important. The EPA reports that indoor levels of airborne pollutants may be 2-5 times higher (in extreme cases more than 100 times higher) than outdoor levels. That means allergens, mildew, dust and pollutants can be circulating in your home and affecting your family’s health.

Q: What is the most efficient thermostat setting for air conditioning?
A: The ideal setting is the highest temperature at which you feel comfortable. For many people this ranges from about 75 to 78 degrees. As a general rule of thumb, raising the thermostat setting by 2 degrees can reduce cooling costs by 5 percent.

Q: How does my air conditioner work?
A: Heat is extracted from the home by passing indoor air across a refrigerant coil. Refrigerant lines carry the heat from your home to the outdoor unit, where it is released into the outside air. A fan blows air across the chilled coils into your home. The cooling cycle continues until the indoor temperature reaches the thermostat setting. The process is explained in this video from How Stuff Works. And you can find a more detailed explanation (along with more helpful information and tips) in this Energy Saver 101 infographic from the U.S. Department of Energy.
