Clean Air Heating & Air Conditioning Co., Inc.

Clean Air Heating & Air Conditioning Co., Inc. has served Baltimore since 1972, making it one of the longest-operating family-owned HVAC contractors in the metropolitan area. With a 4.7-star rating across 92 reviews, the company holds a Maryland HVAC license and employs certified technicians who install and service residential and light commercial equipment across Baltimore City, Anne Arundel County, Harford County, and Howard County. The office sits at 1911 Portal Street in Dundalk, with separate phone lines for sales and service and a toll-free number for outlying callers.

What distinguishes this contractor from regional competitors is its breadth of specialized systems. Clean Air installs and services ductless mini-split setups for homes where running ductwork is impractical, and it is a certified Aprilaire installer for whole-house steam humidifiers and air-filtration units. The company also handles geothermal heat-pump installations, which leverage stable ground temperatures for year-round efficiency. Financing options are available for qualified buyers, and current seasonal specials and rebate programs are posted on the website.

Customer reviews repeatedly name technicians who went beyond the scope of a single repair visit. Technicians Mitchell and Marvin spent several hours replacing both primary and secondary heat exchangers on a furnace, cleaning the water trap, burners, and coils while walking the homeowner through what the old exchangers looked like and answering every question. Technician Mike installed an Aprilaire Series 800 steam humidifier to replace a failing bypass unit, correctly handling mounting height, condensation angle, and ductwork-only second-floor distribution, then followed up with the manufacturer to resolve a hammering noise in the copper feed tube at no extra charge.
