With the nearing end of the summer season and coming winter how do families protect their cooling system and make sure it is ready for next year? With the rising costs of fuel and the uncharacteristically hot summers throughout the US it is more important than ever to extend the life of your home’s air conditioning unit. A high-quality heating ventilation and air conditioning system can last up to 20 years if properly installed and maintained. However, the cheapest models or poorly maintained systems can fail in as little as 5. Here are 10 tips to make sure your air conditioner is ready for next year.
1. Make sure all weather stripping around doors and windows is properly sealed. As time goes by the caulking and weather stripping become compromised with use and temperature changes and the loss of the conditioned air can cause the air conditioner and heater to work longer to achieve the desired temperature.
2. Screening AC installers for professional credentials, experience and proper training is extremely important. If the unit has been installed improperly, the system may have leaky ducts or low air flow. Often, the level of refrigerant does not match the manufacturer’s specifications, which can affect efficiency and performance. Improper installation can lower a system’s efficiency by up to 30 percent.
3. Changing or cleaning the air filter is one of the most important maintenance tasks. Clogged, filthy filters obstruct air flow and can even impair the evaporator coil’s ability to absorb heat. Filters should be attended to every month or two, depending on how much dust or pet fur a home has. A good contractor will show homeowners how to do this simple task themselves.
4. It is important to keep an eye out for warning signs of a failing system, such as: loud or strange noises, a system that turns on and off a lot, longer run times, strange smells emanating from the unit, or higher than normal energy bills.
5. Installing and using a programmable thermostat is a great way to improve the longevity of central air. This enables homeowners to pre-program the unit to turn off while they are away from the home or increase in temperature. Energy Star studies say a programmable thermostat can save homeowners about $180 a year in energy costs.
6. Sealing and insulating ducts can improve a cooling system’s efficiency by 20 percent or more. Often ducts that run through attic crawl spaces, basements and garages become extremely hot during the day, which causes the air conditioner to work harder to cool these surfaces. Also, poorly sealed ducts can leak cool air outside of the home and waste energy.
7. Buying high-performance AC units with Energy Star labels and high SEER numbers will not only ensure greater longevity for the system, but can also decrease cooling costs by nearly $500 a year. Upfront cost should not be the only consideration in choosing a system for the home.
8. Getting adequate airflow through the outdoor condenser coils is important as well. Homeowners should periodically check outside to ensure there are no weeds, shrubs or other obstructions. One can also turn off the circuit breaker to the unit, remove the outdoor cabinet and clean out debris that has accumulated inside. Many people hose down the unit after every lawn mowing to keep grass clippings out.
9. Keep pets away from the condenser. It may sound crazy, but it’s not at all uncommon for a system to fail in 5 years due to a pet using the bathroom on the unit and corroding the cooling coil fins’ metal.
10. Annual maintenance scheduled regularly is the best way to ensure the whole system is operating properly. A technician will top off fluids, check electrical connections for safety, clean and lubricate all moving parts, change the filter, adjust blower components for comfort, and inspect the system for signs of wear and tear. According to Houston air conditioning company, Air Depot, many families fail to have routine maintenance and as a result have to replace systems or parts that can cost in the thousands of dollars.
