All About the Lennox Merit Series ML16XP1 Heat Pump

Buying a brand-new heat pump, or any other household appliance for that matter involves certain adjustments. You’d want to make the most of your recent purchase and what better way to achieve this than making sure you know the best practices.

Four Seasons Air Specialists is your leading HVAC company in Grant MN. In this article, we offer tips on how to maximize your new heat pump.

Using the Auto Mode

Setting the heat pump to AUTO mode may seem like an efficient way to operate your HVAC system. However, using this mode can cause your heat pump to switch between heating and cooling when it doesn’t have to. Therefore, instead of using the AUTO mode, set it to “HEAT” in winter and “COOL” in summer.

Setting the Fan

While higher fan speeds make louder sounds, but a heat pump is most efficient when it’s set to a high fan speed. So, set it on the highest fan speed you’re comfortable with, then, select your desired temperature.
