Did you know that the average lifespan of an HVAC unit is 12 to 15 years? As much as we wish it weren’t true, we occasionally need to decide whether it’s worth making costly repairs over purchasing a brand-new unit. Replacing an old, out-of-date heating or cooling system reduces your energy costs and gives you peace of mind. Make your residence more comfortable by switching to a new energy-efficient system that will save you money! Design Mechanical Inc. can help change your air conditioner or heating system to a reliable new one. We serve the Clayton, Garner, and Fuquay Varina, NC area.
