Your home’s cooling system can last up to 15 years, at least when it’s properly cared for. Whether you have a traditional air conditioner or a ductless mini split heat pump, your system needs consistent TLC. At CARJON, we are a local, family-owned Rhode Island business, not a private equity firm. Our long-tenured technicians treat your home like their own, using their expertise to catch the small problems that other companies miss, before they turn into expensive failures. We want you to live in a world of total comfort, so we’ve put together these AC maintenance tips to ensure your system remains healthy and efficient for years to come.

1. Change Your Air Filters

Your AC’s air filter has a crucial function: to keep dust and other debris from getting into the air you breathe. Air filters should be changed every 30-90 days; otherwise, the accumulation of debris can clog airflow, impacting your system’s efficiency and your energy bills. Some air conditioners have reusable air filters that should be regularly cleaned as often as you would normally change a disposable air filter.

2. Keep Your Windows Closed 

It’s recommended to keep your windows closed when your air conditioner is running, to avoid excess pollutants and moisture getting circulated into your duct system that can affect your indoor air quality. Additionally, your air conditioner’s main job is to maintain a comfortable temperature in your home, and keeping your windows open will just result in wasted electricity as it cycles to do this task.

3. Check Your Outdoor Unit

As the heart of your cooling system, the outdoor compressor is responsible for converting heat into cool, conditioned air. This essential part of your AC or heat pump is also left out with the elements all year long, making it susceptible to damage from landscaping and other debris. A malfunctioning compressor is one of the most expensive air conditioning repairs that often requires a full system replacement, making it an important component to maintain.  

4. Install a Programmable Thermostat

Zoned systems and programmable thermostats allow you to maximize the efficiency of your HVAC system. These technologies give you room-by-room temperature control and often allow you to adjust your settings from an app. At CARJON, we offer several options for zoned HVAC systems throughout Rhode Island and can help find the right one for your specific needs.

5. Call CARJON For Cooling Maintenance

Spending the time and money to have your AC professionally tuned up annually is one of the most important AC maintenance tips to keep your cooling system running smoothly.
