Lennox HVAC Products for Your Northern VA Home

At M.E. Flow, we are passionate about home comfort. That’s why we install and service HVAC products from top names like Lennox. This innovative brand creates systems to keep your home cooler in the summer and warmer in the winter – all with quiet, energy-efficient operation.

As a Lennox dealer, M.E. Flow is well-equipped to repair, install, replace, and maintain today’s best Lennox systems. The Merit Series has the most affordable purchase price. We install Merit 17 systems and higher. Moving to the Elite Series grants a greater opportunity for energy savings, offsetting the higher upfront investment over time. Finally, the Signature Collection uses the best heating and cooling technology available to achieve up to 28 SEER air conditioning efficiency, 24 SEER/11.8 HSPF heat pump efficiency, and 99 AFUE furnace efficiency.
