Ducane currently offers five AC models ranging from 13 up to 16 SEER.

Ducane was founded in 1946 in New Jersey as the ‘Ducane Brothers Metal Fabricating’ company. Now, Ducane is a subsidiary of Lennox International Inc (Lennox also owns Armstrong Air and others). We repair most major HVAC brands, including these and many others.
We recommend annual maintenance from an HVAC professional for your Ducane heating system. Regular cleaning, inspection and preventive furnace maintenance can go a long way in keeping efficiency up and extending the service life of your equipment.
Seasonal tune-ups and professional air conditioner maintenance can help you control energy bills in summer and reduce the risk of breakdowns during heat waves. We offer maintenance services for all Ducane AC models.
Members of our service plan enjoy spring and fall tune-up services, plus a discount on additional products and services.
Is it time to replace your Ducane furnace or air conditioner? Making the call can be tricky – your new HVAC system is big investment and not an everyday purchase. In general, if repair costs add up to more than half the cost of a new unit, upgrading to a newer and more efficient model is usually called for. The best way to feel confident about replacing your furnace or air conditioner is getting a recommendation from an HVAC professional. We’ll take a look at your current setup and give you our honest opinion. If we can help you get more practical service out of your furnace or AC, we will!
