What Lennox HVAC System Do You Need?

Lennox Air Conditioners

Known for their energy efficiency and their exceptionally quiet performance, Lennox AC systems are designed to save you money and reduce normal AC noise. Lennox air conditioners can cool any size home with ease, and some of their air conditioner units can lower your monthly utility bills by up to 60%.

Lennox Furnaces

The first HVAC system that Lennox sold back in the late 19th and early 20th centuries was a furnace—so you know Lennox offers some of the best furnaces around! If you’re thinking about replacing your heating system, there’s nothing better than a high-efficiency furnace from Lennox. Their furnaces range from 80 to an incredible 98.7 AFUE, so trust that there’s a system to meet your needs and your budget. Most Lennox furnaces come with multi-speed or variable speed blowers and are air filter- and humidifier-compatible, so you can customize them to fit your family’s needs.

Lennox Heat Pumps

Ready to ditch your separate AC and heating systems and install a Lennox heat pump for year-round energy-efficiency? Lennox heat pumps are ranked among the quietest and highest-quality heating and air conditioning products in the industry and can help maintain a comfortable temperature throughout your home. Whether it’s the XP25 Heat Pump or the SL18XP1 Heat Pump, Lennox has the heat pump for your DC or Maryland home.

If you’re in the market for a new air conditioner, heat pump, or furnace, or if you want to improve the indoor air quality within your home, call the experts at Michael Bonsby Heating & Air Conditioning today! We can help you choose the Lennox equipment that’s right for you so you can live comfortably.
