Bel-O Cooling & Heating Insists on Quality

At Bel-O Cooling & Heating in Belleville, we stand behind our work, which means we have to stand behind the products and equipment that we use. Whether you call us for air conditioning, heating, indoor air quality, or plumbing services, you can be sure that we only use high-quality products that we would be happy to install in our own homes. We are also authorized dealers for many of these products, so you can buy them directly from us for maximum convenience. Be sure to also ask about our warranties for certain parts and labor!

We carry these industry-leading products and more:

Daikin: One of the country’s most reputable HVAC companies, Daikin HVAC systems include gas furnaces, air handlers, fit systems, Aurora heat pumps, split system heat pumps, and more.

Carrier: Carrier is an American staple for heating, ventilation, and air conditioning systems, including specialized HVAC systems known for being “ultra-quiet.”

Navien: Tankless water heaters are Navien’s specialty. Navien products are available in both gas and electric models, so there is sure to be one that works for your property.

Halo: A Halo Water Heater System helps keep the operating costs of your water heater low by preventing hard water build-up and removing existing scale.
