Trust in Welzig Heating and Air for dual fuel system services!

Welzig Heating and Air specializes in Hybrid Heat dual fuel systems, which combine the efficiency of an electric heat pump with the strength of a gas furnace.  These systems provide an ideal solution to the extreme weather fluctuations across Boulder, CO and surrounding areas.  Some of the numerous benefits of a dual fuel system include:

• Efficiency – A two-in-one heating system takes advantages of the superior energy efficiency of an electric heating pump, and when the heat pump begins to drop in performance due to weather extremes, the gas furnace takes over.  The combination significantly decreases the cost of operating either of these systems on their own.
• Comfort – For every type of weather, you have the perfect answer, which delivers ideal year-round comfort.  Because the air compressor is placed outside the house, noise levels are kept at a minimum, and your heat pump effectively handles humidity in the summer and won’t overly dry the air in the winter.
• Versatile – Automatically switching between the electric heat pump and the gas furnace, efficiency and comfort are always maintained at the optimum level.  While the heat pump is the best choice when temperatures remain above freezing, the gas furnace will take over during severe cold, so that you always enjoy maximum rewards.
• Cost-effective – The ongoing cost savings of a dual fuel unit increases the value of your home and works to pay for itself.  You’ll save on maintenance and on those monthly energy bills, as you utilize the electric heat pump for the majority of your temperature control requirements.
• Environmentally Responsible – Safe and clean, a dual fuel system relies on electricity about 85% of the time, helping to reduce greenhouse gas emissions.  The electric heat pump also takes advantage of non-ozone depleting Puron refrigerant.
