Most Expensive Appliance

Fixing ac unit

Your HVAC system is the most expensive appliance in your home and works to keep you comfortable day in and day out. Let’s face it…we all take it for granted. We expect that our cooling system will work while never giving it much thought. However, should it break down or malfunction it creates a huge disruption to our lifestyle. Think of it in terms of your car. Without maintenance, aka a tune-up, your car would quit running. The same applies to your HVAC system and yet many homeowners neglect regular maintenance. Maintenance is critical to keeping both your car and your HVAC system working reliably and efficiently while ensuring optimum longevity.


A tune-up for your car ensures that it will continue to get you from place to place every day while reducing the chances of any unplanned repairs. Annual maintenance in terms of your HVAC system ensures that it continues to operate reliably day after day, providing indoor comfort for you and your family, while helping to prevent any future problems and unexpected costs.

Example: As part of a yearly inspection, your HVAC technician will lubricate all moving parts. A lack of lubrication causes resistance in motors and increases your use of electricity. This resistance causes extra wear and tear on your system, requiring more frequent repairs, and reducing the reliability of your system.


According to ENERGY STAR®1, as much as half of the energy used in your home goes to cooling (and heating). Just as a tune-up for your car can improve your gas mileage, a yearly tune-up of your heating and cooling system can improve efficiency.2

Example: As mentioned above, lubricating moving parts will improve the efficiency of your system. Also, as part of your tune-up, your technician will inspect your blower components, cleaning and adjusting them. Airflow problems can reduce your system’s efficiency by up to 15 percent.2 A reduction in the efficiency of your system means higher monthly utility costs.


If you were to quit having the oil changed in your car, it will cause engine components to warp and wear out. Eventually, the entire engine will shut down and need to be replaced. Your HVAC system is no different. Without proper maintenance, your system’s components will wear out quicker and fail years earlier than necessary, leading to premature replacement.

Example: During an A/C system tune-up, your technician will inspect, clean or change air filters. A dirty filter can increase energy costs and damage equipment, resulting in premature failure, which leads to an expensive early replacement of your system.

Regular maintenance, whether for your car or your HVAC system, ensures reliable, efficient, and long-term satisfaction.
