AC System Maintenance

AC system maintenance isn’t a luxury or optional service. It is essential for optimal performance of your heating and cooling unit.

The system consists of multiple moving parts and electrical components that require periodic checks to ensure that they’re working properly. An inspection isn’t expensive, especially when you compare it to the cost of an extensive repair or replacement.

Let’s go over what’s it entails and why it is necessary.


What Is Involved?

The extent of the AC system maintenance required depends on the type of unit and its features. Newer models are more efficient with parts that will likely last longer than older ones.

Your HVAC system is not unlike a car in which components wear out or need readjustment to keep them running with the maximum output.

Some tasks are simple in that the homeowner or DIY’er can do such as cleaning accessible ducts or changing the air filter. Other things require professional service because of federal regulations like handling refrigerants.


Why Regular Checks Matter

The two most important reasons to perform AC system maintenance are improved energy efficiency and longer lifespan of the system. Both can affect your bottom line.

An inspection can identify problems that impact the unit’s performance. They can range from minor issues such as a dirty filter to more significant ones like a faulty compressor. A trouble with a component will cause it to run longer and harder which will drive up your utility bill.

The second reason can have a direct impact on your budget. Often, a technician can do a small repair before it affects the operation of the entire system. The preventive measures you take can go a long way toward saving you money on the cost of a replacement. It’s like insurance for your HVAC system.

Also, most warranties on AC equipment require regular maintenance as part of the conditions. Penguin Cooling and Heating is an authorized warranty dealer for Trane, York, Lennox, and most major brands.

Finally, there is the safety factor. A professional check of the AC unit includes an inspection of the electrical controls. A service call can give you the peace of mind you deserve.



Penguin Cooling and Heating offers a complete inspection service that will thoroughly check your AC system from top to bottom. Our technicians will do the necessary seasonal maintenance to ensure it works at its peak efficiency.

We recommend getting AC system maintenance in the spring before the beginning of the summer season. After all, it’s more convenient to deal with a repair before you need it than when the hot weather starts.

Likewise, we recommend your heating system maintenance in the fall before the colder weather is upon us.

By doing so, you can ensure that your home stays comfortable when the temperature and humidity rise or fall. It’s also an excellent way to improve the indoor air quality of your living space.
