3 Warning Signs of a Failing AC

To help you determine if you need a new cooling system, consider these indicators:

Old air conditioners are considerably less efficient compared to new models, which means they use more fuel to cool your home. If you notice a hike in your electricity bills without a comparable change in your cooling habits, an inefficient AC could be the culprit.

Old cooling systems experience the most issues during the last 2 years of their life, so, if you notice an increasing number of visits from your local AC technician, it may be time to switch to a new air conditioner.

If you notice some rooms are cooler than others, it means your existing air conditioner is no longer able to evenly distribute cool air. While it may be a duct issue, but you can’t negate the possibility that your AC is already deteriorating, especially if it’s more than a decade old.

Features of the Lennox SL18XC1 Air Conditioner

With a Seasonal Energy Efficiency Ratio (SEER) rating of up to 18.50, the Lennox SL18XC1 air conditioner can save you hundreds of dollars in cooling costs per year, compared to older air conditioners.

The condenser coil is the part of the air conditioner that draws hot air from inside your home and releases it outside. The Lennox Quantum™ coil handles the heat like no other. It’s constructed from aluminum alloy, helping it resist corrosion in harsh conditions like coastal environments.


Its iComfort-enabled technology allows the air conditioner, when installed with the easy-to-use programmable iComfort thermostats, to exchange information and make adjustments as needed to optimize performance and efficiency.
