Full-Service HVAC, One Call Away
Michigan weather doesn't mess around — sub-zero January nights and humid 90-degree Julys. Your heating and cooling system has to handle both. Tri-County HVAC Pros keeps tri-county homes comfortable year-round with honest diagnostics, upfront pricing, and workmanship we stand behind.

Common Questions
How fast can you get a technician to my home?
We offer same-day service throughout Oakland, Macomb, and Wayne Counties. Call before noon and we'll usually have a tech out the same day. During heat waves and cold snaps we prioritize no-heat and no-cool calls.
Do you really give free estimates?
Yes. For replacements and installations, estimates are always free — a tech visits, evaluates your home and ductwork, and gives you an upfront written price. Diagnostic visits for repairs carry a flat fee that we waive if you approve the repair.
Are your technicians licensed and insured?
Yes. Every technician is licensed, background-checked, and our work is fully insured. We pull permits where required and our installations meet Michigan mechanical code.
Do you offer financing?
Yes — financing options are available for system replacements and larger repairs, with approved credit. Many homeowners finance a new furnace or AC for less per month than the energy savings.
What brands do you service?
We service all major brands — Carrier, Trane, Lennox, Rheem, Goodman, Amana, York, Bryant, and more. For installations we recommend high-efficiency equipment matched to your home's size and ductwork.
Which areas do you serve?
All of Oakland, Macomb, and Wayne Counties, including Warren, Sterling Heights, Livonia, Troy, Dearborn, Southfield, Royal Oak, Taylor, and surrounding communities.
