Air Conditioner Maintenance

When you schedule preventative maintenance from Level 9 Heating & Cooling, we protect your investment and ensure long-lasting comfort. Annual service is critical for performance and continued operation of your cooling system. By cleaning, tightening and troubleshooting, our certified technicians will eliminate the majority of potential repairs, maximize efficiency, and keep your system running safely.

Replacing Your Air Conditioner Will Lower Your Energy Bills

Without annual inspection, dirt and debris can build up at numerous points, concealed within your system. Organic matter such as pollen, mold spores, colonies of insects and even decomposing rodents can result in bacteria, which is then infused into your home when summer heat prompts the use of your air conditioner. Dirt can also significantly decrease your system’s energy efficiency. As dust, mold, and mildew accumulate, coils are insulated, preventing heat absorption. As airflow is restricted, condensate may possibly even freeze, completely blocking the coil. Overworked motors and greater wear and tear add up to costly repairs. In some cases, the lack of preventative maintenance can cause you to have to replace your air conditioning unit entirely.

The Solution Is Simple, Cost-Effective And Extremely Beneficial

Through annual maintenance, Level 9 Heating & Cooling will restore your air conditioner to the manufacturer’s expectations for efficiency, lowering your monthly energy bills. By cleaning, tightening and lubricating, we’ll significantly extend the lifespan of your system. Simple troubleshooting will make sure you’re never left waiting for replacement parts on the hottest day of summer.
