I already knew W.B.Steward & Son had a well-established reputation for excellence…. In 2015 Company owner Don and his crew provided first rate service before, during, and after their installation of our brand new heating and air-conditioning system. They went the extra mile and made sure I was 100 ...continue reading

W.B. Steward and Son knocked it out of the park with my oil to gas conversion. Right from the start while in the bidding stages of this project I knew Don Steward and his team were going to be the ones I went with. The honesty and integrity that Don puts forth upon meeting him put your mind at ease. ...continue reading

I recently replaced an older heating system with an air conditioning/heating system with W.B. Steward and Son. The existing heating system was loud and did not heat the whole house properly.

Comprehensive Furnace Repair Services

Your furnace represents one of your home’s most critical systems, especially during Gloucester County‘s cold months. We diagnose and repair all furnace types, including natural gas, oil, and electric models. Our technicians carry advanced diagnostic equipment that measures combustion efficiency, carbon monoxide levels, heat exchanger integrity, and electrical system performance. This thorough approach helps us identify issues like cracked heat exchangers, faulty ignition systems, blocked venting, or deteriorating blower motors before they become dangerous or cause complete system failure.

Modern furnaces contain sophisticated control boards and safety devices that require expert knowledge to troubleshoot effectively. We maintain extensive inventories of replacement parts for major brands, allowing us to complete most repairs during the initial service call. Our emergency service means you’re never left without heat when temperatures drop. Whether your furnace produces strange noises, cycles frequently, distributes heat unevenly, or won’t start at all, we have the expertise to restore proper operation quickly.

Professional AC Repair and Cooling Solutions

Air conditioning systems involve complex refrigeration cycles, electrical components, and airflow dynamics that demand professional expertise when problems arise. We service all cooling system types, from traditional split systems to heat pumps and ductless mini-splits. Our technicians use precision instruments to measure refrigerant pressures, superheat, subcooling, and temperature differentials across evaporator coils. These measurements reveal issues like refrigerant leaks, compressor problems, expansion valve failures, or airflow restrictions that reduce cooling capacity and efficiency.

Indoor air quality concerns often stem from AC system problems. Frozen evaporator coils, clogged condensate drains, or microbial growth in drain pans can affect both comfort and health. We address these issues comprehensively, cleaning coils, treating drain systems, and verifying proper humidity control. Our team also evaluates ductwork integrity, as leaky or poorly insulated ducts can waste significant energy and reduce comfort levels throughout your home.

This is NOT a precise estimate for pricing. As professional installers, we will need to inspect and conduct load calculations on your home to provide a price estimate designed for your specific space.
