HVAC Installation
Professional hvac installation from the team Northeast Indiana trusts. Serving Spencerville, Auburn, Garrett, and surrounding communities.
When it comes to HVAC installation, getting it right the first time is everything. An improperly sized or poorly installed system will cost you more in energy bills, break down sooner, and never quite keep your home comfortable. At Graves Plumbing, Heating and A/C, we take the time to do a thorough load calculation for your home, accounting for square footage, insulation levels, window placement, ductwork condition, and the specific climate challenges we face here in Northeast Indiana. Whether you live in Spencerville, Auburn, Garrett, or anywhere across DeKalb and Allen counties, we design every installation around your home — not a one-size-fits-all formula.
We install high-efficiency furnaces, central air conditioning systems, heat pumps, and complete HVAC packages from trusted manufacturers including GE Appliances Air and Water. Every installation includes professional ductwork evaluation, proper refrigerant charging, electrical connections tested to manufacturer specifications, and a full system commissioning to verify everything is running at peak performance before we leave your home. We also walk you through your new system so you know exactly how to operate it and get the most out of your investment.
Financing is available through FTL Finance, making it easy to upgrade to a modern, energy-efficient system with affordable monthly payments. We provide free in-home estimates with transparent, upfront pricing — no hidden fees, no surprise charges. From the first phone call to the final walkthrough, the Graves team treats your home with the same care and respect we would give our own.
