Common Questions and Answers

What are the best practices for maintaining Lennox equipment to minimize downtime?

There are many ways you can keep your Lennox equipment well-maintained in order to minimize any downtime. First, regular cleanings are a must. Whether it's daily, weekly, or monthly, you should always follow an OEM-recommended cleaning schedule. Next, it's vital to regularly check parts and components that wear faster than others-such as gaskets and o-rings-in order to replace them before any related problems arise. You should also train staff on how to properly operate the equipment to avoid any risk of damage. Finally, having your unit inspected by an Authorized service technician will catch any potential issues before they become big problems.

What is SEER?

SEER stands for “Seasonal Energy Efficiency Ratio,” and it’s a measurement used to determine an HVAC unit’s energy efficiency. A unit, like an Air conditioner, with a higher SEER rating uses less energy during operation, thus making it more energy-efficient. The rating scale ranges from 8-21+, with a standard rating range being between 13-16.
