HVAC Repair & Maintenance
Professional hvac repair & maintenance from the team Northeast Indiana trusts. Serving Spencerville, Auburn, Garrett, and surrounding communities.
Your HVAC system works hard to keep your family comfortable through Indiana's hot summers and frigid winters. Like any mechanical system, it needs regular attention to perform at its best — and occasional repairs when something goes wrong. At Graves Plumbing, Heating and A/C, we provide comprehensive HVAC repair and preventive maintenance services to homeowners across Spencerville, Auburn, Garrett, Waterloo, Butler, and the greater DeKalb and Allen county areas.
When your furnace will not ignite, your AC is blowing warm air, or your system is making a noise it should not be making, we respond quickly with same-day service whenever possible. Our technicians arrive with fully stocked service vehicles, diagnose the problem accurately, and explain your options clearly before any work begins. We service all major brands — GE, Carrier, Lennox, Trane, Rheem, Goodman, and more — so no matter what equipment you have, we can help.
Preventive maintenance is where you get the most value for your dollar. Our seasonal tune-ups catch small problems before they become expensive breakdowns, keep your system running efficiently to lower energy bills, and extend the lifespan of your equipment by years. The Department of Energy estimates that regular HVAC maintenance can reduce energy consumption by 5-15% and add 5-10 years to your system's life. We recommend scheduling a heating tune-up in the fall and a cooling tune-up in the spring to stay ahead of the seasons.

Frequently Asked Questions
We recommend twice per year: a heating tune-up in September or October before winter, and a cooling tune-up in April or May before summer. Regular maintenance keeps your system efficient, extends its lifespan, and catches problems before they become expensive emergencies.
It depends on the noise. A low, steady hum is normal operation. Banging, screeching, rattling, or clicking sounds indicate a problem that should be inspected promptly. A bang when the furnace ignites could mean delayed ignition, which can damage the heat exchanger over time. Call us at (260) 927-6910 and describe the sound — we can often give you initial guidance over the phone.
A good rule of thumb: multiply the age of the unit in years by the cost of the repair. If the result exceeds $5,000, replacement usually makes more sense. We will always give you an honest recommendation based on the condition of your equipment, not on what generates the biggest sale.
Yes. We provide 24/7 emergency service for heating and cooling failures. If your system goes down outside of normal business hours, call us at (260) 927-6910 and a technician will respond as quickly as possible.
