Make sure you check the filters in your air conditioning unit. This is important because checking your filters could make the difference between inexpensive repairs and more expensive ones down the line. Try to put it into your monthly schedule so that you don’t forget to check the filters regularly.

One of the most important things to consider when purchasing a new heating and cooling system is the manufacturer’s warranty. Units come with a variety of warranties. Choose one with a long warranty for maximum long term savings. Generally, it is advised that homeowners should purchase the extended warranty if one is offered.

If you have a fan condenser with oil ports, it needs to be lubricated every year. Such ports tend to have coverings made of rubber or metal. Get an oil that is SAE 20 and put about 10 drops into each port, but don’t overfill it.

Be sure to check your evaporator coil drains frequently when your air conditioner is running. If this tube backs up, you can find water damage to your walls, ceilings and floors. If you end up with mold just use a solution of bleach and water to clean out the tube.

If you want to seriously extend the life of your HVAC system, as well as cut down your overall power bill, install ceiling fans in commonly used warm season rooms. Energy-star certified ceiling fans can sometimes cut your HVAC use in half. However, you won’t physically notice a difference in temperature.

If you want to cool your home in the summer without using your air conditioning on full, consider installing fans in your home. An attic fan can blow hot air out while sucking in cool air into your basement, and ceiling fans help distribute the air in your rooms evenly.

If you currently have a manual thermostat, consider installing a programmable one. You can set your system for different temperatures depending on time of day and if anyone is home. Also, you can set upper and lower temperature settings to allow for a comfortable range of temperatures so that heating and cooling don’t kick in when not needed.

Never allow your home to get dangerously hot inside. Air conditioners really can only cool a home down about 20 degrees Fahrenheit within a reasonable amount of time. If your home become 100F or more, it will only cool off to about 80F. While it depends on the humidity, this is not safe for a human to sleep in to recover from the heat of the summer.

It is tough to deny the fact that a failed HVAC system can wreak havoc in the life of any homeowner, particularly during times of extreme weather. Fortunately, there are things that can be done to mitigate the frustration experienced during such events. Using the advice presented above is a great way to stay prepared.
