Avoid Costly HVAC Repair with Preventative Maintenance

There are many reasons our HVAC system mail fail, but many of the most common issues can be avoided by conducting regular preventative maintenance. Even if you do everything right, extreme heat, humidity and cold can stress your heating and cooling system. Purchasing a warranty to protect your system from a well-respected and professional company like American Home Shield (AHS) can help protect your investment from the unforeseen.

The Importance of an Annual Inspection

While you should have an HVAC company on call to check your unit at the beginning of each new season, there are also some basic procedures you should be completing on your own. Regular tune-ups are essential for ensuring that your system runs properly. Even a single annual inspection can reveal issues early on and ensure that your system remains operational for years.

Regular Maintenance Reduces Energy Costs

During an annual inspection, the technician should check a few key points. If you’re technician isn’t checking for these basic issues, then you need to find another technician to maintain your system.

  • Check refrigerant levels
  • Check gas connections
  • Check air filters
  • Tighten all electrical connections
  • Clean condenser coils
  • Lubricate and clean moving parts
  • Check and test all thermostats


Common Mistakes Homeowner’s Make

Once you’ve had your checkup, it’s important to keep up with your own monthly cleaning routine. Filters should be replaced according to the manufacturer’s guidelines. In most cases, you should replace or clean your air filters every one to three months. Some filters are designed to be cleaned with a simple garden hose, while disposable filters require you to purchase a new filter. Also, check to make sure that all the vents in the house are open. Shutting the vents to a room that you never use may seem like a good way to save money on your energy bill, but it can cause the unit to work harder since the intended airflow is blocked. Adjust the vents throughout your home to ensure that air flows freely between rooms, and when possible keep the doors in your home open to encourage free airflow throughout your house.

Fixing Issues with Weak Airflow

Weak airflow may be the result of many issues that don’t require the assistance of a technician. Before calling for a repair, try a few simple steps to see if you can troubleshoot the issue on your own.

  • Check for a dirty air filter. A dirty air filter can block the flow of air and reduce the strength.
  • Make sure all the vents in the home are at least halfway open.
  • Check to ensure that the appropriate filter for your unit is installed. A filter that is too dense can cause problems with smaller units.
  • Check the power source. Go to the circuit breaker and turn the unit off and on. Sometimes this can correct an issue with airflow.
  • Clean the vents and make sure dust is blocking the flow of air.


Proper maintenance can reduce repair costs by up to 40 percent and increase the lifespan of your unit by 30 percent or more. Additionally, an increase of up to 30 percent in energy efficiency can be obtains by fixing any issues before they become problematic. Avoid costly repairs by performing regular maintenance, and get a warranty to protect your system to avoid costly repairs when your system eventually breaks down.
